[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a leveling mechanism for the frame leg provided by an embodiment of the present utility model includes a frame main body 1. A leveling component 2 is arranged on the lower side of the frame main body 1. The leveling component 2 includes a fixed plate 3, an adjusting plate 4, a threaded sleeve 6 and an adjusting screw 7. The adjusting plate 4 is arranged above the fixed plate 3. The adjusting plate 4 is fixedly connected to the bottom of the frame main body 1. The threaded sleeve 6 is fixedly installed above the adjusting plate 4. The adjusting screw 7 is arranged above the fixed plate 3. The adjusting screw 7 is in threaded connection with the threaded sleeve 6. A fixed sleeve 11 is fixedly installed above the fixed plate 3. One end of the adjusting screw 7 is arranged between the fixed sleeves 11. A limiting rotation plate 12 is arranged on the circumferential side of one end of the adjusting screw 7. A limiting rotation groove 13 is formed on the circumferential side of the inner wall of the fixed sleeve 11. The limiting rotation plate 12 is rotatably installed in the limiting rotation groove 13. A reinforcing plate 21 is arranged between the frame main body 1 and the adjusting plate 4.

[0025] Specifically, in this embodiment, when it is necessary to finely adjust the heights of the four legs of the frame main body 1, by rotating the corresponding adjusting screw 7, the adjusting screw 7 rotates stably through the limit rotating plate 12 and the fixed sleeve, and the rotation of the adjusting screw 7 can drive the movement of the threaded sleeve 6, so that the threaded sleeve 6 moves linearly along the adjusting screw 7. The linear movement of the threaded sleeve 6 can drive the linear movement of the adjusting plate 4, and the linear movement of the adjusting plate 4 can drive the legs of the frame main body 1 to move linearly. When the legs of the frame main body 1 are adjusted to the appropriate position, stop rotating the adjusting screw 7, and use the limiting mechanism 8 to fix and limit the adjusting screw. Among them, the fixing plate 3 is fixedly installed on the ground through the expansion bolt 5, which can improve the stability of the leveling assembly 2 and the frame main body 1 during use.

[0026] In a leveling mechanism for the legs of a frame provided by the present utility model, a limiting mechanism 8 is arranged on the upper side of the fixing plate 3. The limiting mechanism 8 corresponds to the adjusting screw 7. The limiting mechanism 8 includes a guiding cylinder 15, a limiting plate 17, a sliding rod 18, a connecting rod 19 and a limiting block 20. The guiding cylinder 15 is fixedly installed on the upper side of the fixing plate 3. A spring 16 is arranged at the bottom of the inner wall of the guiding cylinder 15. The limiting plate 17 is slidably installed in the guiding cylinder 15. The limiting plate 17 is fixedly connected to one end of the spring 16. The sliding rod 18 is arranged above the limiting plate 17. The connecting rod 19 is fixedly installed at the upper end of the sliding rod 18. The limiting block 20 is fixedly installed at the lower side of one end of the connecting rod 19. A limiting slot 14 is opened on the upper side of the adjusting screw 7, and the limiting block 20 is movably inserted into the limiting slot 14.

[0027] In another embodiment provided by the present utility model, when it is necessary to release the limit on the adjusting screw 7, by pulling up the sliding rod 18, the sliding rod 18 drives the connecting rod 19 to move. The movement of the connecting rod 19 can drive the limiting block 20 to move, so that the limiting block 20 disengages from the limiting slot 14 on the upper side of the adjusting screw 7, and thus the limit on the adjusting screw 7 can be released. When fixing, by relaxing the sliding rod 18, the sliding rod 18 drives the connecting rod 19 to move downward through the elastic force of the spring 16. The downward movement of the connecting rod 19 can drive the limiting block 20 to move downward, so that the limiting block 20 is inserted into the limiting slot 14 on the upper side of the adjusting screw 7, and thus the limit on the adjusting screw 7 is completed. Among them, when the sliding rod 18 moves, it will drive the limiting plate 17 to slide along the inner wall of the guiding cylinder 15. The limiting plate 17 can improve the smoothness of the sliding of the sliding rod 18 and can provide a limit to the moving stroke of the sliding rod 18.

[0028] In other embodiments, the sliding rod 18 and the limit plate 17 are rotatably connected via a bearing, so that after the sliding rod 18 drives the limit block 20 to disengage from the limit slot 14 on the upper side of the adjusting screw 7, the sliding rod 18 is rotated to drive the limit block 20 to rotate to one side, thereby preventing the sliding rod 18, the connecting rod 19 and the limit block 20 from obstructing the staff from rotating the adjusting screw 7.

[0029] The utility model provides a frame leg leveling mechanism, wherein nuts 9 are fixedly installed on the upper side of the adjustment plate 4, support bolts 10 are threadedly installed between the nuts 9, and one end of the support bolts 10 is in close contact with the upper side of the fixing plate 3.

[0030] In another embodiment provided by the utility model, the support bolt 10 is rotated so that the support bolt 10 moves along the nut 9, and the support bolt 10 can contact the fixing plate 3 when it moves. By tightly contacting the fixing plate 3 with one end of the support bolt 10, the support bolt 10 can relieve part of the pressure for the adjusting screw 7, and the number of the support bolts 10 is several.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
