[0040] like Figures 1 to 4 As shown, in this embodiment, the table frame structure includes: a frame 10, a side panel structure 20, a first pin structure 30, a column 40, a second pin structure 50, and a locking mechanism 60. The frame 10 has a receiving space 11. The side panel structure 20 is disposed at the end of the frame 10. The first pin structure 30 is disposed between the frame 10 and the side panel structure 20 to allow for a detachable connection between the frame 10 and the side panel structure 20. A mounting portion 41 is provided at the top of the column 40, and at least a portion of the mounting portion 41 is located within the receiving space 11. The second pin structure 50 is disposed between the mounting portion 41 and the frame 10 to allow for a detachable connection between the mounting portion 41 and the frame 10. The locking mechanism 60 is disposed on the mounting portion 41 or on the frame 10, and has a locked position and an unlocked position. When the locking mechanism 60 is in the locked position, it locks the side panel structure 20 and the mounting portion 41 to the frame 10.

[0041] Applying the technical solution of this embodiment, the side plate structure 20 is disposed at the end of the frame 10, and the first pin structure 30 is disposed between the frame 10 and the side plate structure 20. A mounting part 41 is provided at the top of the column 40, and at least a portion of the mounting part 41 is located within the receiving space 11. A second pin structure 50 is disposed between the mounting part 41 and the frame 10. A locking mechanism 60 is disposed on the mounting part 41 or the frame 10, and the locking mechanism 60 can lock the side plate structure 20 and the mounting part 41 onto the frame 10. With the above arrangement, during assembly, the side plate structure 20 and the frame 10 are connected together by the first pin structure 30, and the mounting part 41 and the frame 10 are connected together by the second pin structure 50. Simultaneously, the locking mechanism 60 locks the side plate structure 20 and the mounting part 41 onto the frame 10, thus simplifying the overall assembly process and eliminating the need for complex operations. Therefore, the technical solution of this embodiment effectively solves the problem of complex connection between the column and the frame in related technologies.

[0042] like Figure 2 as well as Figures 5 to 8 As shown, in this embodiment, the side panel structure 20 has a plug-in portion 21, and the frame 10 includes a support beam 12. The plug-in portion 21 can be plugged into the support beam 12. The plug-in portion 21 is provided with a first locking hole 211, and the support beam 12 is provided with a second locking hole 121. The locking mechanism 60 has a locking block 61, and the first locking hole 211 and the second locking hole 121 are correspondingly provided. The locking block 61 can be inserted into the first locking hole 211 and the second locking hole 121. The cooperation between the plug-in portion 21 and the support beam 12 simplifies the installation process of the side panel structure 20. Under the drive of the locking mechanism 60, the locking block 61 is inserted into the first locking hole 211 and the second locking hole 121, realizing a stable connection between the side panel structure 20, the frame 10, and the column 40. This effectively improves the overall stability of the table frame structure and facilitates disassembly and maintenance.

[0043] like Figures 1 to 4 As shown, in this embodiment, the locking mechanism 60 is disposed on the side of the side plate structure 20 facing the mounting portion 41. This arrangement ensures the cooperation between the locking mechanism 60 and the support beam 12 and the insertion portion 21, and also reduces the length of the insertion portion 21, thus effectively reducing costs. The end of the support beam 12 is provided with a mounting hole 122 extending along the length of the support beam 12. The insertion portion 21 can be inserted into the mounting hole 122, and a first pin structure 30 is disposed between the insertion portion 21 and the support beam 12. The mounting hole 122 enables rapid assembly of the side plate structure 20 and the frame 10.

[0044] like Figure 2 as well as Figures 5 to 8As shown, in this embodiment, the top of the support beam 12 is provided with an opening 123. The opening 123 is located at the end of the support beam 12 facing the side plate structure 20 and is connected to the mounting hole 122. The first pin structure 30 is provided between the bottom surface of the support beam 12 and the insertion part 21. The opening 123 allows the insertion part 21 to enter the mounting hole 122 through the opening 123, thereby realizing the assembly of the side plate structure 20 and the support beam 12.

[0045] Specifically, the opening 123 is connected to the mounting hole 122, so that the first pin structure 30 can be smoothly inserted to achieve a stable connection between the side plate structure 20 and the frame 10. Moreover, this assembly method can avoid the first pin structure 30 from affecting the assembly process.

[0046] like Figures 1 to 8 As shown, in this embodiment, the first pin structure 30 includes a first insert 31 and a first slot 32, with the first insert 31 capable of being inserted into the first slot 32. The cooperation between the first insert 31 and the first slot 32 enables rapid assembly of the side plate structure 20 and the frame 10. The first insert 31 includes a column segment 311 and a limiting segment 312, with the column segment 311 positioned between the side plate structure 20 and the limiting segment 312. The first slot 32 includes a clearance hole 321 and a slotted hole 322, which are connected. The limiting segment 312 can be inserted into the clearance hole 321 and can also enter the slotted hole 322. The cooperation between the limiting segment 312 and the clearance hole 321 and the slotted hole 322 enables rapid assembly and stable connection of the side plate structure 20 and the frame 10. Specifically, the limiting segment 312 is inserted into the clearance hole 321, and then the side plate structure 20 is pushed so that the column segment 311 enters the strip hole 322. At this time, the limiting segment 312 is located outside the support beam 12, thereby achieving the limiting along the axial direction of the column segment 311.

[0047] Specifically, in this embodiment, the first insert 31 extends in the vertical direction, that is, under the action of the first pin structure 30, the side plate structure 20 and the support beam 12 are limited in the vertical direction.

[0048] like Figures 1 to 4 as well as Figures 6 to 10As shown, in this embodiment, the second pin structure 50 includes a second pin 51 and a second slot 52. The second pin 51 is disposed on the mounting part 41, and the second slot 52 is disposed on the support beam 12. A limiting groove 212 is provided on the insertion part 21, and the limiting groove 212 is correspondingly disposed with the second slot 52. The second pin 51 can be inserted into the second slot 52 and the limiting groove 212. The cooperation between the second pin 51 and the second slot 52 enables the connection between the mounting part 41 and the support beam 12, and enables the limiting along the length direction of the support beam 12, that is, it can prevent the mounting part 41 and the support beam 12 from moving along the length direction of the support beam 12. At the same time, since the second pin 51 can also cooperate with the limiting groove 212, the position of the side plate structure 20 and the mounting part 41 can be stabilized, that is, the movement of the side plate structure 20 and the mounting part 41 along the length direction of the support beam 12 is restricted. This arrangement can ensure the stability of the side plate structure 20, the support beam 12, and the mounting part 41 along the length direction of the support beam 12. The second pin structure 50 also includes a third pin 53 and a third slot 54. The third pin 53 is spaced apart on the mounting part 41 and spaced apart from the second pin 51. The third slot 54 is spaced apart on the support beam 12 and spaced apart from the second slot 52. The third pin 53 and the third slot 54 are inserted into each other. The third slot 54 is located on the side of the second slot 52 away from the side plate structure 20. The third slot 54 is bent toward the side away from the second slot 52.

[0049] The aforementioned third insert 53 is inserted into the third slot 54, working together with the second pin structure 50 to achieve a stable connection between the column 40 and the frame 10. Simultaneously, because the third slot 54 is bent away from the second slot 52, the third insert 53 can enter the bent section of the third slot 54, thus limiting the mounting part 41 and the support beam 12 along the height direction and preventing separation between them.

[0050] like Figures 1 to 6 as well as Figures 9 to 12As shown, in this embodiment, the locking mechanism 60 further includes a housing 62, a reset member 63, a moving member 64, and an operating member 65. The housing 62 has a first through hole 621 and a second through hole 622 located on adjacent surfaces. The locking block 61 and the operating member 65 are both connected to the moving member 64. The moving member 64 is movably disposed inside the housing 62 and cooperates with the reset member 63. The operating member 65 protrudes from the housing 62 through the first through hole 621. The locking block 61 is inserted into and extends out of the second through hole 622. Through the cooperation of the reset member 63 and the moving member 64, automatic locking and unlocking of the locking block 61 are achieved. The operating member 65 protrudes from the housing 62 through the first through hole 621. When the operating member 65 is operated, the moving member 64 moves, causing the locking block 61 to insert into or exit the second through hole 622, thereby locking or unlocking the side plate structure 20 and the frame 10. This design simplifies the operation of the locking mechanism 60 and improves the assembly efficiency of the table frame structure.

[0051] like Figures 1 to 4 As shown, the assembly process of the table frame structure in this embodiment is as follows: First, the insertion part 21 of the side panel structure 20 is inserted into the mounting hole 122 of the support beam 12. Specifically, the insertion part 21 is inserted into the mounting hole 122 through the opening 123. At this time, the first pin 31 of the first pin structure 30 is inserted into the first slot 32, realizing the initial connection between the side panel structure 20 and the frame 10. Then, the top mounting part 41 of the column 40 is tilted so that the third pin 53 is inserted into the third slot 54. The mounting part 41 is pushed so that the third pin 53 enters into the bent section of the third slot 54. Then, the mounting part 41 is swung to insert the second pin 51 into the second slot 52, that is, the column 40 and the frame 10 are initially connected through the second pin structure 50. Finally, the locking mechanism 60 is operated so that the locking block 61 is inserted into the first locking hole 211 and the second locking hole 121, realizing the stable locking of the side panel structure 20, the column 40 and the frame 10.

[0052] The assembly process described above requires no additional tools, is simple and quick to operate, and improves the assembly efficiency and stability of the table frame structure. During use, the locking mechanism 60 keeps the locking block 61 locked, ensuring the stability of the table frame structure. When it is necessary to disassemble or adjust the table frame structure, the operating part 65 of the locking mechanism 60 is operated in reverse to disengage the locking block 61 from the first locking hole 211 and the second locking hole 121, allowing for easy disassembly or adjustment of the table frame structure.

[0053] According to another aspect of this application, a height-adjustable desk is provided. This embodiment of the height-adjustable desk includes a table frame structure, which is the table frame structure described above. The table frame structure described above enables rapid assembly, and the assembly process is relatively simple. Therefore, the height-adjustable desk with the table frame structure described above also has the aforementioned advantages.

[0054] In the description of this utility model, it should be understood that "multiple" means a quantity of two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
