[0049] As shown in FIG. 1 to FIG. 6, this embodiment provides a pole mechanism, including: upright post 1 with a hollow structure, a pole assembly, and a locking assembly. The pole assembly includes slider 2 and gripping housing 3 disposed on the slider 2. The gripping housing 3 is connected to the slider 2 by a bolt. The slider 2 is slidably connected to the upright post 1. The locking assembly includes second limiting member 4, unlocking member 7, and first limiting member 5 disposed on the upright post 1. The unlocking member 7 is at least partially located outside the gripping housing 3. The second limiting member 4 is at least partially disposed inside the gripping housing 3. The second limiting member 4 cooperates with the first limiting member 5 to limit the slider 2 at a desired position on the upright post 1. The unlocking member 7 is disposed on the second limiting member 4 to unlock the second limiting member 4 and the first limiting member 5. Through unlocking by the unlocking member 7, the slider 2 is slidable up and down along the upright post 1. The pole mechanism has a simple structure, facilitating processing, maintenance, transportation, and carrying.

[0050] Furthermore, a side of the upright post 1 is provided with first groove 6. The first groove 6 is disposed along a length direction of the upright post 1. The first limiting member 5 is disposed at a bottom of the first groove 6. The slider 2 is disposed in the first groove 6. Spring 13 is disposed between the second limiting member 4 and the gripping housing 3, and the spring 13 is configured to reset the second limiting member 4.

[0051] As shown in FIG. 13, in some embodiments, connecting rod 25 is sleeved outside the upright post 1, and the gripping housing 3 is disposed outside the connecting rod 25.

[0052] In some embodiments, the second limiting member 4 includes integrally formed annular member 11 and cylindrical member 12. The cylindrical member 12 is disposed on the annular member 11. The annular member 11 is sleeved outside the upright post 1. The gripping housing 3 is disposed outside the annular member 11. The slider 2 is provided with a limiting hole. The cylindrical member 12 is at least partially located in the limiting hole. The first limiting member 5 includes multiple first through-holes disposed along the length direction of the upright post 1. One end of the cylindrical member 12 is inserted into the first through-hole to limit the pole assembly at a desired position (desired height) on the upright post 1. The unlocking member 7 is disposed on a side of the annular member 11 away from the cylindrical member 12. When the unlocking member 7 is pressed, the cylindrical member 12 is disengaged from the first through-hole. Specifically, the annular member 11 is a closed structure formed by an irregular arc. The gripping housing 3 is disposed outside the annular member 11, and its shape corresponds to the shape of the annular member 11. The gripping housing 3 is provided with grip portion 10. A gap is provided between the grip portion 10 and the upright post 1. The gap is provided to facilitate operation by a human hand. The unlocking member 7 is disposed outside the grip portion 10. When a user presses the unlocking member 7, the palm of the user faces the unlocking member 7, that is, force is applied by the palm to press the unlocking member 7. This facilitates exertion of force by the user's hand, allowing the user to adjust the position of the slider 2 in an effort-saving and convenient manner. A side of the gripping housing 3 away from the grip portion 10 is substantially fitted to the upright post 1. A mounting groove is provided on an outer side of the grip portion 10, and the unlocking member 7 is at least partially exposed from the mounting groove. A portion of the unlocking member 7 located in the mounting groove is connected to the annular member 11. When the unlocking member 7 is pressed, the unlocking member 7 drives the annular member 11 and the cylindrical member 12 to move in a direction away from the grip portion 10, thereby disengaging the cylindrical member 12 from the first through-hole. When the cylindrical member 12 is disengaged from the first through-hole, the pole assembly is movable up or down along the upright post 1. Preferably, the unlocking member 7 is a plate-shaped structure made of plastic.

[0053] As shown in FIG. 6, to further facilitate operation, an inner side of the grip portion 10 is provided with multiple indentations, preferably four indentations. The shape of the indentations fits four human fingers (excluding the thumb), facilitating the user to hold the grip portion 10. Preferably, an anti-slip texture structure can be disposed above the grip portion 10 to enhance friction between the human hand and the grip portion 10, thereby preventing the hand from slipping off during operation of the grip portion 10.

[0054] As shown in FIG. 8 and FIG. 9, particularly, the cylindrical member 12 includes integrally formed first segment and second segment. A diameter of the first segment is smaller than a diameter of the second segment. The second segment includes one end connected to the first segment and the other end connected to the annular member 11. The first segment is inserted into the first through-hole to limit the pole assembly at a desired position on the upright post 1. When the unlocking member 7 is pressed, the first segment is disengaged from the first through-hole, but the first segment is still located in the limiting hole. The limiting hole serves a guiding and limiting function, facilitating the cylindrical member 12 to quickly enter the first through-hole.

[0055] As shown in FIG. 7 and FIG. 10, the second segment has a hollow structure. An end of the second segment close to the first segment is provided with an cover plate. The spring 13 is disposed in the second segment. The spring 13 includes one end abutting against the cover plate and the other end abutting against the gripping housing 3. The spring 13 is configured to reset the second limiting member 4. Specifically, the gripping housing 3 includes a first portion and a second portion. The first portion is the grip portion 10, and the second portion is substantially an inverted U-shaped structure. Two ends of the grip portion 10 are connected to the second portion by bolts. An inner side of the inverted U-shaped structure is substantially fitted to the upright post 1. The second portion is internally provided with strip-shaped accommodating groove 8. The shape of the strip-shaped accommodating groove 8 corresponds to the shape of the second limiting member 4. When the unlocking member 7 is pressed, the second limiting member 4 moves together in a direction away from the grip portion 10. Therefore, due to the strip-shaped accommodating groove 8, the gripping housing 3 expands the accommodating space for the second limiting member 4 without increasing its volume. When the unlocking member 7 is not pressed, the second limiting member 4 does not enter or does not completely enter the strip-shaped accommodating groove 8. When the unlocking member 7 is pressed, a side of the second limiting member 4 close to the strip-shaped accommodating groove 8 enters the strip-shaped accommodating groove 8. The second portion is further provided with two opposite arc-shaped grooves 9. The two arc-shaped grooves 9 enclose a space for accommodating the cylindrical member 12. One end of the spring 13 abuts against the cover plate, and the other end thereof is located in the space enclosed by the two arc-shaped grooves 9.

[0056] In some embodiments, the first limiting member 5 is a rack disposed along the length direction of the upright post 1, and the second limiting member 4 is a tooth-shaped structure. The rack cooperates with the tooth-shaped structure to limit the slider 2 at a desired position on the upright post 1.

[0057] As shown in FIG. 11, FIG. 12, and FIG. 15, to facilitate smooth sliding of the slider 2, two inner walls of the first groove 6 are respectively provided with a first sliding groove and a second sliding groove. The first sliding groove is internally provided with multiple first sliding rollers 14, and the second sliding groove is internally provided with multiple second sliding rollers 15. The number of the first sliding rollers 14 is equal to the number of the second sliding rollers 15, and the first sliding roller 14 and the second sliding roller 15 are disposed opposite to each other. The slider 2 is disposed between the first sliding roller 14 and the second sliding roller 15. The slider 2 is not in direct contact with the first groove 6. When the slider 2 slides, the first sliding rollers 14 and the second sliding rollers 15 slide in the first sliding groove and the second sliding groove, respectively, thereby reducing friction between the slider 2 and the upright post 1. The first sliding roller 14 is provided with a first connecting hole, the second sliding roller 15 is provided with a second connecting hole, and the slider 2 is provided with multiple third connecting holes. The third connecting hole transversely passes through the slider 2. The number of the third connecting holes is equal to the number of the first sliding rollers 14. A bolt passes through the first connecting hole, the second connecting hole, and the third connecting hole to connect the first sliding roller 14, the second sliding roller 15, and the slider 2. That is, the first sliding roller 14 and the second sliding roller 15 are respectively located at two sides of the third connecting hole. The bolt passes through the first connecting hole, the second connecting hole, and the third connecting hole respectively to connect each group of the first sliding roller 14 and the second sliding roller 15 to the slider 2.

[0058] As shown in FIG. 13 and FIG. 14, in an embodiment of the present disclosure, limiting piece 17 is disposed in the first groove 6. The bottom of the first groove 6 is provided with a first mounting hole. The limiting piece 17 is provided with a second mounting hole. A bolt passes through the first mounting hole and the second mounting hole to connect the limiting piece 17 to the upright post 1. The first mounting hole is disposed above the first limiting member 5. The limiting piece 17 is configured to limit the slider 2. Specifically, the limiting piece 17 is disposed at an upper portion of the upright post 1. When the pole assembly slides upward along the upright post 1 to the limiting piece 17, the pole assembly cannot continue sliding upward. The limiting piece 17 prevents the pole assembly from sliding excessively upward along the upright post 1 to damage rib assembly 20.

[0059] Furthermore, limiting ring 16 is sleeved outside the upright post 1. The limiting ring 16 is disposed below the first limiting member 5. The limiting ring 16 is configured to limit the slider 2. When the pole assembly slides downward along the upright post 1 to the limiting ring 16, the pole assembly cannot continue sliding downward. The limiting ring 16 prevents the pole assembly from sliding excessively downward along the upright post 1 to damage the rib assembly 20.

[0060] As shown in FIG. 16 to FIG. 18, another embodiment of the present disclosure provides an outdoor umbrella, including a pull rod assembly, rib assembly 20, and the pole mechanism in the above embodiment. The pull rod assembly includes first pull rod 18 and second pull rod 19. The slider 2 is provided with connecting piece 22. The first pull rod 18 includes one end connected to the rib assembly 20 and the other end connected to the connecting piece 22. The second pull rod 19 includes one end hinged to the first pull rod 18 and the other end hinged to the upright post 1. Specifically, the connecting piece 22 is connected to the slider 2 by a bolt, and the connecting piece 22 moves together with the slider 2 on the upright post 1. The specific structures of the pull rod assembly and the rib assembly 20 are similar to those in the prior art, and will not be detailed in the present disclosure.

[0061] Furthermore, an end of the first pull rod 18 close to the connecting piece 22 is provided with cord reel assembly 24 and crank handle 23. The crank handle 23 is configured to drive the cord reel assembly to rotate. The cord reel assembly 24 rotates to retract or release an umbrella cord. The cord reel assembly 24 and the crank handle 23 are disposed on the first pull rod 18, rather than on the upright post 1, thereby preventing the umbrella cord from knotting or tangling at the connection between the upright post 1 and the first pull rod 18. The design also greatly simplifies the structure of the pole assembly, facilitating the forming process of the gripping housing 3 and subsequent maintenance. Furthermore, since the cord reel assembly 24 and the crank handle 23 are disposed on the first pull rod 18, the gripping housing 3 does not need to reserve mounting sites for the cord reel assembly 24 and the crank handle 23. Therefore, the gripping housing 3 is lighter and more compact, facilitating transportation and carrying of the outdoor umbrella. Besides, since the cord reel assembly 24 and the crank handle 23 are disposed on the first pull rod 18, the mounting space of the pole assembly is freed. Because the first pull rod 18 is rod-shaped, the first pull rod 18 has a relatively simple structure, preventing its storage from being affected by the cord reel assembly 24 and the crank handle 23.

[0062] To make the outdoor umbrella more stable during use, base 21 is disposed below the upright post 1. Specifically, the base 21 includes a cross-shaped skeleton. Due to the base 21, the outdoor umbrella can adapt to severe weather conditions, such as strong winds or rainstorms, and the outdoor umbrella will not tip over due to severe weather.

[0063] The present disclosure is described in detail above. Specific cases are used herein to illustrate the principle and implementation of the present disclosure, and the description of the above embodiments is only intended to help understand the core idea of the present disclosure. It should be noted that several improvements and modifications may also be made by those of ordinary skill in the art without departing from the principles of the present disclosure, which also fall within the protection scope of the claims of the present disclosure.
