DESCRIPTION OF EMBODIMENTS

[0022] The following describes the above and additional embodiments and advantages of the present invention clearly and completely with reference to the accompanying drawings. It is evident that the described embodiments are only some, but not all, of the embodiments of the present invention.

[0023] In one embodiment, as shown in FIGS. 1 to 6:

[0024] The present embodiment provides a push-type sunshade umbrella, comprising a tubular standing pole 1. A plug seat 2 is provided at the top of the standing pole 1. A hand-sliding sleeve 3 is slidably mounted on the standing pole 1. A scissor frame 4 is disposed beside the standing pole 1. The inner of one unit rod of the scissor frame 4 is hinged upward to the plug seat 2, while the inner of the other unit rod is hinged downward to the hand-sliding sleeve 3. A perforation 5 is formed on the side of the standing pole 1 back-facing the scissor frame 4, corresponding to the maximum ascending position of the hand-sliding sleeve 3. A first longitudinal reinforcement rod 6 and a second longitudinal reinforcement rod 7 are provided at the bottom of the plug seat 2 and extend into the standing pole 1. The second longitudinal reinforcement rod 7 is arranged on an opposite side of the perforation 5 relative to the first longitudinal reinforcement rod 6. A notch 8 is formed on the side of the second longitudinal reinforcement rod 7 facing the first longitudinal reinforcement rod 6. A transverse locking rod 10 is disposed at the bottom of the first longitudinal reinforcement rod 6. One end of the transverse locking rod 10 passes through the perforation 5 and is ejected into the hand-sliding sleeve 3, while the other end thereof is inserted into the notch 8. An elastic trigger rod 9 is provided between the notch 8 and the bottom of the second longitudinal reinforcement rod 7. The end of the elastic trigger rod 9 located within the notch 8 forms a compressive triggering relationship with the transverse locking rod 10, while the other end thereof abuts against the hand-sliding sleeve 3 to supply potential energy to the transverse locking rod 10.

[0025] The tubular standing pole 1 serves as the foundational support component of the overall structure. The plug seat 2 provided at its top is used to secure the upper hinge point of the scissor frame 4, thereby ensuring the stability of the scissor frame 4 during the unfolding process. The two unit rods of the scissor frame 4, an expansion mechanism, are connected to the plug seat 2 and the hand-sliding sleeve 3 via hinge points, respectively, thereby enabling the deployment and retraction functions of the umbrella ribs. The perforation 5, as part of the locking mechanism, must be precisely positioned to ensure alignment with the transverse locking rod 10 when the hand-sliding sleeve 3 reaches its maximum ascending position. The first longitudinal reinforcement rod 6 and the second longitudinal reinforcement rod 7 serve to enhance the overall strength of the standing pole 1. Among them, the first longitudinal reinforcement rod 6 may be configured as a round or rectangular tube, while the second longitudinal reinforcement rod 7 is provided with a notch 8 on one side to accommodate the transverse locking rod 10 and disperse stress. The transverse locking rod 10, as the core component of the locking mechanism, may incorporate a spring or other elastic component at one end to provide reset functionality, while the other end cooperates with the elastic trigger rod 9 via an inclined surface structure to achieve automatic locking. The elastic trigger rod 9 functions as an energy storage and release device, capable of storing potential energy through compression springs or other elastic materials and releasing it under specific conditions to drive the transverse locking rod 10 to complete the locking action.

[0026] Under the aforementioned structural conditions, the specific working principle of this embodiment is as follows: the hand-sliding sleeve 3 slides upward along the standing pole 1 and, through the hinge connection with the lower end unit rod of the scissor frame 4, interacts with the push rod to unfold the umbrella ribs. When the hand-sliding sleeve 3 ascends to its maximum position, the perforation 5 on the side of the standing pole 1 back-facing the scissor frame 4 aligns with the locking position on the hand-sliding sleeve 3, providing a path for the transverse locking rod 10. At this point, the internal structure of the hand-sliding sleeve 3 contacts the bottom of the elastic trigger rod 9 and applies an upward thrust to it. Under this thrust, the elastic trigger rod 9 moves upward along the cavity of the second longitudinal reinforcement rod 7, causing its end located in the notch 8 to contact the transverse locking rod 10. This drives the transverse locking rod 10 to sequentially pass through the perforation 5 and into the locking position on the hand-sliding sleeve 3 (e.g., a locking hole 32 opposite to the perforation 5 is formed on the hand-sliding sleeve 3), thereby quickly and simultaneously locking the hand-sliding sleeve 3.

[0027] In summary, in this embodiment, one end of the transverse locking rod 10 provided at the bottom of the first longitudinal reinforcement rod 6 passes through the perforation 5 into the hand-sliding sleeve 3 to achieve transverse locking, while the other end is inserted into the notch 8 of the second longitudinal reinforcement rod 7, forming a primary longitudinal force-bearing relationship. Through the secondary force-bearing relationship between the second longitudinal reinforcement rod 7 and the plug seat 2, the hand-sliding sleeve 3 forms at least one transverse and at least two dual longitudinal force-bearing structures on the tubular standing pole 1, thereby balancing the lateral tilting force exerted on the standing pole 1 by the scissor side. The elastic trigger rod 9 is positioned between the bottom of the second longitudinal reinforcement rod 7 and the notch 8. The end of the elastic trigger rod 9 located within the notch 8 forms a compressive triggering relationship with the transverse locking rod 10, while the other end presses against the hand-sliding sleeve 3 to store potential energy. When the hand-sliding sleeve 3 ascends to its maximum position, the elastic trigger rod 9 releases the potential energy, driving the transverse locking rod 10 to eject and complete the locking action, ensuring a smooth and reliable locking process. Thus, by redesigning the locking mechanism, this technical solution disperses the stress of traditional safety pins, which acts directly on the pinhole of the standing pole 1, into the longitudinal reinforcement rods and the notch 8 structure. This effectively resolves stress concentration and shear force problems caused by persistent lateral tilting forces generated by the unilateral arrangement of the scissor frame 4 and enhancing the safety of the sunshade umbrella during long-term use.

[0028] In another embodiment, the top of the plug seat 2 serves as a decorative section 22, while the bottom of the plug seat 2 is a metal connection section 21. The metal connection section 21 is connected inside the top of the standing pole 1 through screw threads. The first longitudinal reinforcement rod 6 and the second longitudinal reinforcement rod 7 are fixed on the metal connection section 21.

[0029] In this embodiment, the top of the plug seat 2 serves as the decorative section 22 to enhance aesthetic appeal. The bottom of the plug seat 2 is the metal connection section 21, which may be made from high-strength metallic materials such as stainless steel or aluminum alloy. This design aims to leverage the high rigidity and deformation resistance of metallic materials. The fixation of the first longitudinal reinforcement rod 6 and the second longitudinal reinforcement rod 7 onto the metal connection section 21 establishes a direct force transmission path, thereby increasing the locking strength between the first and second longitudinal reinforcement rods 6 and 7 and the transverse locking rod 10. This strength is further transmitted via the metal connection section 21 to the entire standing pole 1, serving to uniformly distribute the lateral tilting force from the scissor side and prevent structural damage due to partial stress concentration. The threaded connection of the metal connection section 21 inside the top of the standing pole 1 provides precisely adjustable fastening torque, ensuring a tight and gapless connection interface while facilitating installation and maintenance. The structural connection between the plug seat 2 and the two longitudinal reinforcement rods fundamentally enhances the bonding strength between the plug seat 2 and the standing pole 1, effectively addressing the risk of connection failure caused by lateral tilting forces, which in turn maintains the reliability and durability of the entire actuating mechanism.

[0030] In yet another embodiment, the side of the second longitudinal reinforcement rod 7 back-facing the first longitudinal reinforcement rod 6 is closely abutted against the cavity wall of the standing pole 1.

[0031] In this embodiment, closely abutted refers to a contact state without gaps between the second longitudinal reinforcement rod 7 and the cavity wall of the standing pole 1. The purpose is to eliminate stress non-uniformity caused by the unilateral arrangement of the scissor frame 4, while also transmitting lateral shear forces to the second longitudinal reinforcement rod 7, which in turn transfers them to the cavity of the standing pole 1 on the cavity wall closer to the shear force. This fundamentally enhances the structural rigidity and force uniformity inside the standing pole 1. As the scissor frame 4 of the sunshade umbrella is arranged only on one side of the standing pole 1, lateral tilting forces under the opened-umbrella state are continuously transmitted to the entire wall of the standing pole 1, preventing force accumulation in partial areas. This significantly improves the deformation resistance of the support structure under dynamic loads, further optimizes the stability of the locking mechanism, and ensures long-term reliability of the umbrella structure in the deployed state.

[0032] In yet another embodiment, the first longitudinal reinforcement rod 6 is inserted along the axis of the standing pole 1 into its tubular cavity. The top of the hand-sliding sleeve 3 is provided with an extension section 31, the inner side of which fits the outer wall surface of the standing pole 1 and extends upward along the standing pole 1. The extension section 31 is provided with a locking hole 32 corresponding to the perforation 5. For example, if the standing pole 1 is an elliptical tube, the inner side of the extension section 31 is an arc surface fitting the curved side surface of the elliptical tube, ensuring that the hand-sliding sleeve 3 does not rotate axially during ascent and that the locking hole 32 aligns with the perforation 5.

[0033] In this embodiment, the insertion of the first longitudinal reinforcement rod 6 along the axis of the standing pole 1 effectively enhances the torsional resistance of the standing pole 1 under unilateral forces, providing a uniform support foundation for the entire locking mechanism. The tight fit between the inner side of the extension section 31 of the hand-sliding sleeve 3 and the outer wall surface of the standing pole 1 eliminates gaps between them, significantly suppressing potential lateral shift or wobbling of the hand-sliding sleeve 3 during sliding. The upward-extending structure of the extension section 31 along the standing pole 1 prolongs the guiding path to ensure that the hand-sliding sleeve 3 maintains a straight-line trajectory throughout its ascent, thereby reducing alignment errors caused by cumulative path deviations. The position of the locking hole 32 is precisely matched so that when the hand-sliding sleeve 3 reaches its maximum ascending position, its ascending end contacts the elastic trigger rod 9 while simultaneously aligning the locking hole 32 with the perforation 5 on the standing pole 1. This ensures that the transverse locking rod 10 is driven by the elastic trigger rod 9 to pass through unobstructed, avoiding additional shear forces due to misalignment. The cooperation between the extension section 31 and the first longitudinal reinforcement rod 6 significantly improves the positioning accuracy and structural stability of the hand-sliding sleeve 3 under lateral tilting forces, effectively reduces stress concentration risks in the perforation 5 area, and extends the service life of the locking mechanism. Furthermore, this solution, in combination with the overall structure of the aforementioned push-type sunshade umbrella, further optimizes the reliability and safety of the locking mechanism, addressing safety hazards associated with stress concentration at pin holes in traditional sunshade umbrellas.

[0034] In yet another embodiment, a button 311 is fixed on the outer side of the extension section 31. The internal trigger end of the button 311 extends into the locking hole 32, while the external pressing end of the button matches the contour of a thumb.

[0035] The button provided on the outer side of the extension section 31 allows the user to simply press with the thumb to complete the unlocking action of the transverse locking rod 10 within the locking hole 32. This quickly releases the locking of the hand-sliding sleeve 3 on the standing pole 1, causing the hand-sliding sleeve 3 to slide downward along the standing pole 1. As the upper end of the sleeve moves away from the elastic trigger rod 9, the restraint at the bottom of the elastic trigger rod 9 is eliminated. Simultaneously, the top of the elastic trigger rod 9 disengages from the transverse locking rod 10, causing the transverse locking rod 10 to retract elastically. The hand-sliding sleeve continues to slide downward, causing the scissor frame 4 on the scissor side to fold inward, thereby closing the sunshade. The button 311 may be made with a spring-loaded pin from the prior art, and the button 311 itself, being well-known in the prior art, will not be elaborated further herein.

[0036] In yet another embodiment, the first longitudinal reinforcement rod 6 is a rectangular tube. A transverse mounting hole 61 is provided at the bottom end of the rod along the width direction of the standing pole 1. The transverse locking rod 10 is installed through the transverse mounting hole 61. A nut 101 is mounted on the transverse locking rod 10, and a first return spring 102 is sleeved over the transverse locking rod 10. Both ends of the first return spring 102 are elastically supported between the tubular cavity of the first longitudinal reinforcement rod 6 and the nut 101. The end of the transverse locking rod 10 extending into the notch 8 is provided with an inclined driving switching head 103. A stepped hole 71 is formed inside the bottom of the second longitudinal reinforcement rod 7, and the elastic trigger rod 9 is slidably inserted into the stepped hole 71. The top of the trigger rod extends into the notch 8 and abuts against the inclined surface of the driving switching head 103, while its bottom extends beyond the bottom of the second longitudinal reinforcement rod 7 and is provided with a driving connection section 91. A second return spring 92 is elastically supported between the driving connection section 91 and the step of the stepped hole 71, with the second return spring 92 being sleeved over the elastic trigger rod 9. The driving connection section 91 abuts against the hand-sliding sleeve 3.

[0037] In this embodiment, the first longitudinal reinforcement rod 6 serves as a key component for providing structural support and positioning functions. It may be implemented as a high-rigidity tubular structure using a metal rectangular tube. The purpose is to enhance overall rigidity and installation accuracy through the rectangular tube form, thereby addressing the stress concentration problem caused by lateral tilting forces. The transverse mounting hole 61 is a through-hole structure for installing the transverse locking rod 10, ensuring precise transverse positioning of the transverse locking rod 10 to avoid additional stress due to shaking.

[0038] In this embodiment, by designing the first longitudinal reinforcement rod 6 as a rectangular tube structure, the overall rigidity and installation accuracy are significantly enhanced. This ensures that the transverse mounting hole 61 bears forces uniformly, thereby effectively dispersing stress concentrations caused by lateral tilting forces. The transverse locking rod 10 is installed through the transverse mounting hole 61, with its travel limited by the nut 101. In conjunction with the first return spring 102, it absorbs and cushions impact forces, thereby reducing stress peaks at the perforation 5.The inclined driving switching head 103 provided at one end of the transverse locking rod 10 forms a compressive relationship with the top of the elastic trigger rod 9. When the top of the elastic trigger rod 9 ascends and presses against the inclined surface of the driving switching head 103 (during umbrella deployment), it drives the transverse locking rod 10 to move linearly toward the perforation 5. At this point, the nut 101 compresses the first return spring 102 and stores potential energy for return. Conversely, when the top of the elastic trigger rod 9 descends and disengages from the inclined surface of the driving switching head 103 (during umbrella retraction), the compressive force on the transverse locking rod 10 is eliminated. The first return spring 102 then releases the potential energy for return, pushing the nut 101 to retract the transverse locking rod 10 from the perforation 5, thereby releasing the locking mechanism.

[0039] In this embodiment, the stepped hole 71 inside the second longitudinal reinforcement rod 7 provides stable sliding guidance for the elastic trigger rod 9 and accommodates the installation of the second return spring 92. The driving connection section 91 extending from the bottom of the elastic trigger rod 9 directly contacts the add-on structure at the ascending end of the hand-sliding sleeve 3. When the driving connection section 91 pushes the elastic trigger rod 9 upward (during umbrella deployment), the driving connection section 91 compresses the second return spring 92 and stores potential energy for return. Conversely, when the add-on structure at the ascending end of the hand-sliding sleeve 3 disengages from the driving connection section 91 and descends (during umbrella retraction), the second return spring 92 releases the potential energy and pushes the driving connection section 91 to drive the elastic trigger rod 9 to descend and return.

[0040] In yet another embodiment, a channel 11 is formed on the side of the standing pole 1 facing the scissor frame 4. The add-on structure at the ascending end of the hand-sliding sleeve 3 refers to: a directional pushing section 33, which extends upward or protrudes upward from the inner top of the hand-sliding sleeve 3. The directional pushing section 33 enters the inside of the standing pole 1 via the channel 11, serving to proactively push the driving connection section 91.

[0041] In this embodiment, the directional pushing section 33 serves to ensure that when the hand-sliding sleeve 3 ascends to its maximum position, it can proactively provide an upward thrust to the driving connection section 91. The channel 11 functions as a guiding structure for the ascending and descending of the directional pushing section 33, while also preventing rotation of the hand-sliding sleeve 3. It constrains the directional pushing section 33 to move along a predetermined trajectory (the driving connection section 91), thereby avoiding lateral shift of the hand-sliding sleeve 3 during sliding. The directional pushing section 33 is integrated inside the hand-sliding sleeve 3 and moves synchronously with it, eliminating potential gaps that may arise from external add-on components. When the hand-sliding sleeve 3 slides upward, the directional pushing section 33 enters the inside of the standing pole 1 along the channel 11 and directly acts on the driving connection section 91, steadily transmitting the sliding potential energy of the hand-sliding sleeve 3 to the driving connection section 91. This ensures the accuracy and reliability of the triggering action, substantially enhancing the long-term reliability of the locking mechanism.

[0042] In still another embodiment, the locking hole 32 and the perforation 5 are long slots, the length of which is greater than the width of the transverse locking rod 10.

[0043] In this embodiment, the locking hole 32 refers to an opening structure with a specific geometric shape, which can be implemented by forming an elongated through-slot on the extension section 31 of the hand-sliding sleeve 3. Its purpose is to provide a greater tolerance space to accommodate positional deviations of the transverse locking rod 10 so that the transverse locking rod 10, after passing through the perforation 5, can effectively lock into the locking hole 32. Additionally, during button-based unlocking, it facilitates the withdrawal of the inside of the button from the locking hole 32.
