[0032] like Figure 1 As shown, this utility model provides an adjustable tire mold repair frame, which has a support frame 1, wherein a lifting frame 2 is vertically slidably connected inside the support frame 1, and a horizontal plate 21 is fixedly installed at each of the four corners of the lifting frame 2.

[0033] A first transmission assembly 11 is fixedly installed on the inner bottom wall of the right side of the support frame 1, a second transmission assembly 12 is fixedly installed on the inner top wall of the right side of the support frame 1, and a third transmission assembly 13 is fixedly installed on the inner top wall of the left side of the support frame 1.

[0034] The lifting frame 2 is fixedly installed with a first square rod 31 and a second square rod 32. The first square rod 31 and the second square rod 32 are provided with a support plate 3 with a cross-section in the shape of the letter "L". The first square rod 31 and the support plate 3 are hinged together by a hinge 33, and the second square rod 32 and the support plate 3 are hinged together by a telescopic mechanism 34.

[0035] Optionally, in the above technical solution, the first transmission assembly 11, the second transmission assembly 12, and the third transmission assembly 13 have the same structure, each including two bearing seats 14 fixedly installed on the inner wall of the support frame 1. Each of the two bearing seats 14 is rotatably connected to a rotating shaft 15 through bearings. Two inner sprockets 16 and two outer sprockets 17 are symmetrically fixedly installed on the rotating shaft 15.

[0036] A drive motor 18 is fixedly installed on the outer wall of the bottom right side of the support frame 1. The output shaft of the drive motor 18 is connected to the rotating shaft 15 of the first transmission assembly 11 through a coupling.

[0037] Optionally, in the above technical solution, the three outer sprockets 17 on the front and rear sides of the first transmission assembly 11, the second transmission assembly 12, and the third transmission assembly 13 are connected to a long chain 22. One end of the long chain 22 is fixedly installed on the top wall of the left horizontal plate 21 through the chain link A23, and the other end of the long chain 22 is fixedly installed on the bottom wall of the right horizontal plate 21 through the chain link A23.

[0038] Optionally, in the above technical solution, short chains 24 are connected to the two inner sprockets 16 on the front and rear sides of the first transmission assembly 11 and the second transmission assembly 12. One end of each short chain 24 is fixedly installed on the top wall of the right side horizontal plate 21 through a chain link B25, and the other end of each short chain 24 is fixedly installed on the bottom wall of the right side horizontal plate 21 through a chain link B25.

[0039] Optionally, in the above technical solution, limit blocks 20 are fixedly installed on the front wall of the front side plate 21 and the rear wall of the rear side plate 21.

[0040] Optionally, in the above technical solution, a limiting plate 10 corresponding to the position of the horizontal plate 21 is fixedly installed on the front outer wall and the rear outer wall of the support frame 1. A sliding groove is vertically opened in the limiting plate 10, and the limiting block 20 is slidably connected in the corresponding limiting plate 10.

[0041] Furthermore, the telescopic mechanism 34 includes a telescopic cylinder 35 and two hinge seats 36. The hinge seats 36 are respectively hinged to both ends of the telescopic cylinder 35. The hinge seats 36 are respectively fixed to the upper end of the long side outer wall of the support plate 3 and the right wall of the second square rod 32. The hinges 33 are respectively fixed to the left wall of the first square rod 31 and the lower end of the short side outer wall of the support plate 3.

[0042] Among them, the drive motor 18 is a geared motor that can rotate in both directions. When the motor rotates in the forward direction, it drives the rotating shaft 15 to rotate clockwise, causing the lifting frame 2 to move down. When the motor rotates in the reverse direction, it drives the rotating shaft 15 to rotate counterclockwise, causing the lifting frame 2 to move up.

[0043] Working principle:

[0044] In the initial state, the lifting frame 2 is at the lowest end of the stroke. When in use, the tire mold is placed on the support plate 3 so that the outer circumference of the tire mold abuts against the short side of the support plate 3 and the bottom wall of the tire mold abuts against the long side of the support plate 3.

[0045] When workers need to process the tire mold, they can change the height of the tire mold by adjusting the height of the lifting frame 2 and change the angle of the tire mold by adjusting the angle of the support plate 3.

[0046] The height adjustment method of the lifting frame 2 is as follows: Start the drive motor 18 to drive the rotating shaft 15 of the first transmission component 11 to rotate along the bearing seat 14, and at the same time drive the inner sprocket 16 and the outer sprocket 17 to rotate in place. Under the action of the inner sprocket 16 and the outer sprocket 17 of the second transmission component 12 and the third transmission component 13, the long chain 22 and the short chain 24 on the first transmission component 11 cause the rotating shaft 15 of the second transmission component 12 and the third transmission component 13 to rotate in the same way. As a result, the long chain 22 drives the horizontal plate 21 at the left end to move upward through the chain link A23, and the short chain 24 drives the horizontal plate 21 at the right end to move upward through the chain link B25, so that the lifting frame 2 moves smoothly upward along the limit plate 10.

[0047] The angle adjustment method of the support plate 3 is as follows: start the telescopic cylinder 35 to extend its movable end and push the end connected to the support plate 3 to move upward, so that the support plate 3 rotates counterclockwise; start the telescopic cylinder 35 to retract its movable end and drive the end connected to the support plate 3 to move downward, so that the support plate 3 rotates clockwise.

[0048] 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, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
