DESCRIPTION OF EMBODIMENTS

(8) Please refer to FIG. 1 to FIG. 6:

(9) The present disclosure provides a single-leg height-adjustable table with a with rotation and height-adjustment functions, which includes a table frame, on which a tabletop is mounted. The table frame includes a crossbar 1 at the uppermost end. The tabletop includes a side tabletop 2 and a turnover tabletop 3, the side tabletop 2 is fixed on the crossbar 1, and the turnover tabletop 3 is rotatably connected with the crossbar 1. The side tabletop 2 and the turnover tabletop 3 can be spliced and abutted to form a tabletop with a complete appearance for users to use.

(10) In this embodiment, as shown in FIGS. 1 and 2, the crossbar 1 is used to support the side tabletop 2 and the turnover tabletop 3, so as to maintain the horizontal alignment and stable connection between them when the table is in use, and form a coherent and seamless overall working plane. This method not only ensures the stability and structural strength of the tabletop in use, but also significantly improves the comfort of users by reducing the unevenness or shaking between tabletops. In addition, this supporting structure further optimizes the space utilization efficiency, makes the tabletop conversion more flexible and convenient, and meets the use requirements in different scenarios, thus improving the user experience as a whole.

(11) In order to improve the stability of splicing between the side tabletop 2 and the turnover tabletop 3, in other embodiments (not shown), locks such as snaps, buckles, plug-in locks, electronic latches and the like can also be disposed between the side tabletop 2 and the turnover tabletop 3. Therefore, when the side tabletop 2 and the turnover tabletop 3 are spliced into a whole tabletop, the side tabletop 2 and the turnover tabletop 3 are fixed through the locks, so that the splicing stability can be improved and the turnover tabletop 3 can be prevented from shaking or being jerky.

(12) In this embodiment, as shown in FIG. 3, an angle adjuster 4 is connected between the crossbar 1 and the turnover tabletop 3. The angle adjuster 4 includes a first base 41 and a gas spring 42 which is rotatably connected with the first base 41. The base is fixed at the bottom of the turnover tabletop 3, and one end of the gas spring 42 is rotatably connected with the crossbar 1. The gas spring 42 can expand and contract, and can be automatically maintained at the length after expansion or contraction when being applied with a load. The gas spring 42 is a well-known technology, and the principle of expansion and contraction of the gas spring 42 will not be described in detail in this application.

(13) Therefore, by disposing the telescopic gas spring 42, the turnover tabletop 3 can be pushed to overturn, so that the turnover tabletop 3 can be overturned in an inclined, vertical or horizontal state, as shown in FIGS. 5 and 6. Moreover, the unique rapid and accurate expansion and contraction performance of the gas spring 42 is utilized, which greatly promotes the fluency and efficiency of the folding and overturning operations of the tabletop, and is suitable for children, the elderly and the user groups who need to adjust the tabletop frequently, thus greatly improving the convenience. This method not only improves the traditional tabletop adjustment mode, but also improves the user's comfortable feeling and operating comfort by reducing the physical labor intensity. Moreover, the stability and safety of the tabletop in different states are ensured by the gas spring 42.

(14) In order to achieve the above object, in this embodiment, as shown in FIGS. 3 and 4, the connecting end of the turnover tabletop 3 and the crossbar 1 is a first rotation end joint 8, and the connecting end of the gas spring 42 and the crossbar 1 is a second rotation end joint 9. There is a distance between the first rotation end joint 8 and the second rotation end joint 9, and the first base 41 and the second rotation end joint 9 are spaced apart with an adjustable spacing. Therefore, when the gas spring 42 is extended, the turnover tabletop 3 rotates around the first rotation end joint 8, and the gas spring 42 rotates around the second rotation end joint 9. The turnover tabletop 3 is rotatably connected with the crossbar 1 by the hinges 31, and the side surface of the crossbar 1 and the bottom surface of the turnover tabletop 3 are configured to be flat for the hinges 31 to be installed. The turnover tabletop 3 can rotate around the crossbar 1 through the hinges 31, and the gas spring 42 can smoothly push the turnover tabletop 3 to turn over through the matched configuration of the first rotation end joint 8 and the second rotation end joint 9.

(15) The rotary connection between the turnover tabletop 3 and the crossbar 1 is not limited to the connection by hinges 31, and in other embodiments (not shown), advanced rotary connection modes such as hinge connection, pin shaft connection and rotating shaft connection can also be adopted. Hinge connection has excellent stability and durability, which is suitable for occasions that need to bear heavy load or rotate frequently. Pin connection is suitable for lightweight and reducing the cost-effectiveness of processing and manufacturing because of its simple structure and easy maintenance. Rotating shaft connection is smoother, which is suitable for occasions with higher requirements for rotation. By providing this diversified rotation connection mode, the rotation mode of the turnover tabletop 3 is more flexible and configurable, so that users can choose the most suitable rotation connection solution according to different use occasions, functional requirements and aesthetic preferences, thereby enhancing the universality and market competitiveness of products.

(16) Furthermore, it has been mentioned that the first rotation end joint 8 and the second rotation end joint 9 are space apart with a certain spacing, which refers to the diagonal length of the rectangular cross section of the crossbar 1. If the spacing is too short, the size of the gas spring 42 is required to be high, and it may be difficult to purchase the conventional gas spring 42 that meets the requirements. Therefore, an angle adjusting seat 10 is added to the crossbar 1, and one end of the gas spring 42 is hinged to the angle adjusting seat 10 so as to be rotationally connected with the crossbar 1. The angle adjusting seat 10 extends the spacing between the first rotation end joint 8 and the second rotation end joint 9, so that the size requirement for the gas spring 42 is reduced, which is in line with the actual use situation.

(17) In this embodiment, as shown in FIG. 3, the angle adjusting seat 10 is a groove structure, which not only provides great convenience for the installation of the gas spring 42, but also ensures the accuracy and stability of the installation. The groove structure enables the gas spring 42 to be easily embedded and fixed at a predetermined position, thus effectively supporting the multi-angle adjustment of the turnover tabletop 3 and meeting the needs of users in different usage scenarios.

(18) In other possible embodiments (not shown), the angle adjusting seat 10 may also be a connecting rod structure, and the connecting rod structure may also be set to be telescopic. With the telescopic connecting rod structure, the user is allowed to freely adjust the length of the angle adjusting seat 10 within a certain range, thus realizing fine adjustment of the height of the tabletop. This function meets the individual needs of users with different heights, and at the same time, the telescopic property of the connecting rod structure also enhances the adaptability and durability of the table, so that it can be better adapted for various complex use environments.

(19) Of course, the angle adjusting seat 10 can also be configured in other shapes (not shown), such as an L-shape or any other shape adapted for the installation or rotation of the gas spring 42.

(20) In this embodiment, the first base 41 includes a first adjusting handle 43, and the user can control the extension or shortening of the gas spring 42 by manipulating the first adjusting handle 43. The first base 41 has structures and components related to pneumatic control, which are in the prior art and will not be described here.

(21) In other embodiments (not shown), the gas spring 42 may also be replaced by other telescopic parts, such as an electric telescopic rod. The motor and transmission mechanism are integrated in the electric telescopic rod, and the fast and stable telescopic action can be realized by external power supply, so that the turnover tabletop 3 can be overturned in an electric way, which not only simplifies the operation flow of users, but also significantly improves the accuracy and stability of overturning. With the use of the electric telescopic rod, the overturning and folding process of the tabletop becomes more convenient and efficient. The user can control the expansion and contraction of the electric telescopic rod only by simple key operation to drive the turnover tabletop 3 for angle adjustment or to be completely folded. This method not only meets the user's demand for tabletop flexibility, but also improves the overall experience by reducing the complexity of manual operation.

(22) As shown in FIG. 1, FIG. 2 and FIG. 3, in this embodiment, the table frame further includes a telescopic table leg 5 and a table base 7. The table base 7 abuts against the ground, the telescopic table leg 5 is connected with the table base 7. The upper end of the telescopic table leg 5 is connected with the crossbar 1 through a second base 6, which includes a second adjusting handle 61 capable of controlling the extension or shortening of the telescopic table leg 5, thereby controlling the height of the tabletop.

(23) In this embodiment, the telescopic table legs 5 also extend and retract in a pneumatic way, and the second base 6 has structures and components related to pneumatic control, which are in the prior art and will not be described in detail here.

(24) In other embodiments (not shown), the telescopic table leg 5 can also be extended and retracted by electric means, or a lead screw extension mechanism can be used instead. In this way, the appropriate telescoping mode can be selected according to different application scenarios.

(25) In this embodiment, a hidden caster wheel 71 is connected with the lower end face of the table base 7. A blocking plate 32 is provided at the upper end of the side of the turnover tabletop 3 far from the first base 41.

(26) By disposing the hidden caster wheel 71, the appearance is beautiful and the caster wheel 71 can be prevented from being damaged by collision. By disposing the blocking plate 32, when the turnover tabletop 3 is overturned, articles on the tabletop are easy to slide down, therefore the blocking plate 32 is added to prevent articles from sliding down and falling to the ground.

(27) In this embodiment, as shown in FIG. 3, the blocking plate 32 is fixedly connected with the turnover tabletop 3 by bolts, so that the connection of the blocking plate 32 is more stable.

(28) In other possible embodiments of the blocking plate 32 (not shown), the blocking plate 32 and the turnover tabletop 3 can also be connected in a telescopic manner. For example, an accommodating slot is formed on the turnover tabletop 3, and the blocking plate 32 is inserted into the accommodating slot and slidably connected with the storage slot. When the blocking plate 32 needs to be used, a part of the blocking plate 32 can be pulled out of the accommodating slot to fold the edge of the turnover tabletop 3. When not in use, the blocking plate 32 can be retracted into the storage slot for accommodation. In this way, when the turnover tabletop 3 is folded, the blocking plate 32 will not affect the folding of the turnover tabletop 3, so that the space can be fully utilized and the tabletop of the table can be more beautiful.

(29) The working principle of the present disclosure is as follows: a rotatable turnover tabletop 3 is installed on a crossbar 1, and an angle adjuster 4 with a gas spring 42 is installed between the crossbar 1 and the side tabletop 2; wherein one end of the gas spring 42 is mounted on the crossbar 1 and is capable of rotation; when the gas spring 42 is extended, one end of the turnover tabletop 3 is lifted up, so that the purpose of rotating and accommodating the tabletop is realized; and the angle adjuster 4 is close to the lower end of the turnover tabletop 3 as a whole, so that the structure is compact and does not affect the placement of legs of users.
