Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-6 This utility model provides an embodiment of a rotating desktop structure for an office desk, comprising a lifting platform 4, a rotating bolt 25 installed at the lower end of the desktop 3, a second threaded groove 24 opened at the lower end of the desktop 3, and a fixing sleeve 5. The upper end of the lifting platform 4 has a rotating groove 12, and the rotating bolt 25 is rotatably installed within the rotating groove 12. The outer wall of the lifting platform 4 is provided with a first external thread 13, the lower inner wall of the fixing sleeve 5 is provided with an internal thread 19, the upper outer wall of the fixing sleeve 5 is provided with a second external thread 20, and the rotating bolt 25 is fixedly connected to the center of the upper inner wall of the second threaded groove 24. The office desk also includes a hollow support column. 2. Threaded rod 10, lifting platform 4, fixed sleeve 5, table 3 and lifting block 16. The inner wall of the hollow support column 2 is rotatably installed with threaded rod 10. The lower end of threaded rod 10 is connected to a hexagonal bolt head 11 through the lower end of hollow support column 2. Four sets of support rods 15 are fixedly connected to the lower edge of the lifting platform 4, which are equidistantly distributed around the inner wall of the lifting platform 4. The lower end of the support rod 15 is fixedly connected with lifting block 16. The upper and lower ends of the lifting block 16 are provided with a first threaded groove 17 through the center. The lower edge of the table 3 is provided with a wrench groove 23. Magnetic blocks 22 are installed on the inner walls of both ends of the wrench groove 23.

[0019] The built-in hexagonal bolts allow the adjustment of the threaded rod 10, which drives the lifting block 16 and the lifting platform 4 to adjust the height of the table 3. At the same time, the table 3, which is rotatably connected to the lifting platform 4 via the rotating bolt 25, can be rotated. The threaded lifting adjustment fixing sleeve 5 can position and fix the table 3 after rotation adjustment. The two work together to ensure the lifting and orientation adjustment of the table 3 while making the structure compact and not taking up extra space.

[0020] Please see Figure 2 In this embodiment, a movable frame 1 is fixedly connected to the lower end of the hollow support column 2. Two sets of symmetrically distributed reinforcing ribs 8 are fixedly connected between the movable frame 1 and the hollow support column 2. A threaded rod 10 is rotatably installed inside the hollow support column 2. The lower end is driven by a hexagonal wrench 6 to form a hidden transmission structure, which not only ensures the support strength but also avoids safety hazards and aesthetic impact caused by exposed transmission components. Movable wheels 7 are installed at the four corners of the lower end of the movable frame 1. Four sets of equidistantly distributed support rods 15 connect the lifting platform 4 and the lifting block 16 to form a stable triangular support structure, which distributes the load of the table 3, improves the overall stability, and avoids tilting or deformation caused by single-point force.

[0021] Please see Figures 4-6 In this embodiment, the lifting block 16 is disposed inside the hollow support column 2, the fixing sleeve 5 is fitted onto the outer wall of the lifting platform 4, the hexagonal wrench 6 is disposed inside the wrench groove 23, the rotating bolt 25 is rotatably installed in the rotating groove 12, and the second screw groove 24 cooperates with the rotating bolt 25, which facilitates quick assembly and disassembly of the table 3 and the structure below, and allows the table 3 to be finely adjusted in the horizontal direction to adapt to different usage scenarios. The lower outer wall of the fixing sleeve 5 is fixedly connected to a rotating ring 18, and a hand grip groove 21 is provided through the lower edge of the table 3. The lower outer wall of the lifting platform 4 is fixedly connected to a limiting ring plate 14, and the wrench groove 23 at the edge has a built-in magnetic block 22 to store the wrench tool for adjustment and prevent loss.

[0022] Please see Figures 3-6In this embodiment, the hex wrench 6 is adapted to the hex bolt head 11, the outer wall of the lifting block 16 is in contact with the inner wall of the hollow support column 2, the outer wall of the support rod 15 is in contact with the inner wall of the limiting groove 9, the threaded rod 10 is adapted to the first threaded groove 17, and the lifting block 16 achieves vertical lifting by cooperating with the threaded rod 10 through the first threaded groove 17. The transmission accuracy is high, and the threaded structure has self-locking properties, which can stably maintain the height after adjustment. The first external thread 13 is adapted to the internal thread 19, the second external thread 20 is adapted to the second threaded groove 24, the hex wrench 6 is adapted to the wrench groove 23, the upper end of the lifting platform 4 is in contact with the lower end of the table 3, and the first external thread 13 on the outer wall of the lifting platform 4 is in contact with the internal thread 19 at the lower end of the fixing sleeve 5. The verticality of the lifting platform 4 can be adjusted by rotating the fixing sleeve 5, or further tightened after lifting to enhance the structural rigidity.

[0023] When it is necessary to adjust the height of the tabletop 3, first take the hex wrench 6 out of the wrench slot 23 at the bottom of the tabletop 3 and insert it into the hex bolt head 11 at the bottom of the hollow support column 2. Then rotate the hex wrench 6 to drive the threaded rod 10 inside the hollow support column 2 to rotate. Since the threaded rod 10 meshes with the lifting block 16, the lifting block 16 moves up and down along the inner wall of the hollow support column 2. The lifting block 16 drives the lifting platform 4 to move up and down synchronously through the support rod 15, and finally realizes the height adjustment of the tabletop 3. When it is necessary to adjust the placement angle of the table 3, first hold the rotating ring 18 to drive the fixed sleeve 5 to rotate, so that the fixed sleeve 5 moves downward along the outer wall of the lifting platform 4, thereby causing the second external thread 20 on the fixed sleeve 5 to move out of the second thread groove 24, so as to unlock the fixation between the table 3 and the lifting platform 4. Next, by rotating the tabletop 3 with the rotating bolt 25 at the bottom and the rotating slot 12 at the top of the lifting platform 4, the tabletop 3 can be directly pushed to rotate around the rotating bolt 25, thus adjusting the orientation of the desktop. After rotating to the target angle, no additional locking is required. The upper end of the lifting platform 4 fits tightly with the lower end of the table 3. By tightening the fixing sleeve 5, the thread is reset and installed into the second screw groove 24 to assist in fixing the table 3, so as to prevent the table 3 from rotating at will. After adjustment, put the hex wrench 6 back into the wrench slot 23. The magnetic block 22 in the slot will attract the wrench to prevent it from being lost. Holding the desk hand grip slot 21 at the bottom of the tabletop 3 will make it easier to push the tabletop 3. To fix the overall position, simply step on the locking mechanism of the moving wheel 7; to move it, unlock it and push the desk using the moving frame 1.

[0024] Through the above steps, by combining the threaded transmission lifting and the bolt groove rotation, the same lifting platform 4 not only bears the lifting power of the tabletop 3, but also provides rotation support. The structure is compact and does not take up extra space, which solves the problem that the height and orientation of the existing simple office desk are relatively fixed and difficult to adjust during daily use.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
