[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] Reference Figure 1-4 As shown, a roller skate assembly for a lifting platform comprises a mounting frame 1, a spring damper 101 is installed at the middle of the top of the mounting frame 1, the other end of the spring damper 101 is fixedly connected to a mounting plate 102, a lower connecting plate 103 is symmetrically fixed to the top of the mounting frame 1, a support arm 104 is internally rotatably connected to the lower connecting plate 103, the other end of the support arm 104 is internally rotatably connected to an upper connecting plate 105, the bottom end of the mounting plate 102 is symmetrically fixed to an upper connecting plate 105, a large circular hole 106 is provided on the outer side of the support arm 104, a pulley 107 is internally rotatably connected to the mounting frame 1, mounting holes 108 are penetrated at the four corners of the top of the mounting plate 102, rectangular grooves 2 are symmetrically provided on the left and right sides of the mounting frame 1, a strip groove 201 is penetrated at the bottom end of the rectangular groove 2, a pressure dividing mechanism 3 is provided on the left and right sides of the mounting frame 1, and a limiting mechanism 4 is provided inside the rectangular groove 2;

[0027] Example 1

[0028] The mounting plate 102 is fixed to the bottom end of the lifting platform by bolts to realize the movement of the lifting platform and improve the applicability of the lifting platform. When the lifting platform transports heavy objects, the lifting platform squeezes the mounting plate 102, and the mounting plate 102 squeezes the spring damping 101. When the mounting plate 102 descends, the support arm 104 rotates downward. When the large circular hole 106 on the support arm 104 abuts against the fixed column 304, the support arm 104 squeezes the partition plate 301, and the limit block 403 is released from the square groove 303. The partition plate 301 drops down, and when the supporting foot 305 is flush with the pulley 107, the partition plate 301 stops sliding, and the two supporting feet 305 share the pressure of the pulley 107 to prevent the pulley 107 from deforming due to excessive pressure. The upper end of the square groove 303 is provided with a rounded corner to facilitate the separation of the partition plate 301 and the limit block 403. When the supporting foot 305 is flush with the pulley 107, the bottom end of the limit block 403 abuts against the top end of the connecting plate 302 to prevent the partition plate 301 from resetting.

[0029] Reference Figure 5 As shown, the pressure dividing mechanism 3 includes a partition plate 301, a connecting plate 302 and a square groove 303. The partition plate 301 is slidably connected to the outer side of the mounting frame 1, the connecting plate 302 is fixedly connected to the inner side of the partition plate 301, the connecting plate 302 is slidably connected to the inside of the rectangular groove 2, the square groove 303 is opened on the inner side of the connecting plate 302, a fixing column 304 is fixedly connected to the middle of the top end of the partition plate 301, and a supporting foot 305 is fixedly connected to the middle of the bottom end of the partition plate 301;

[0030] The connecting plate 302 is configured as an L-shaped structure. When the partition plate 301 slides downward, the connecting plate 302 is inserted into the strip groove 201 to prevent the partition plate 301 from being separated from the mounting frame 1 .

[0031] Reference Figure 6 As shown, the limiting mechanism 4 includes a receiving groove 401, a limiting spring 402 and a limiting block 403. The receiving groove 401 is opened inside the rectangular groove 2, one end of the limiting spring 402 is fixedly connected to the inside of the receiving groove 401, the inside of the receiving groove 401 is slidably connected to the limiting block 403, and the other end of the limiting spring 402 is fixedly connected to the inner side of the limiting block 403;

[0032] Example 2

[0033] When the partition plate 301 slides downward, the limit block 403 squeezes the limit spring 402. Since the upper end of the square groove 303 is provided with a rounded corner, the limit block 403 squeezes the limit spring 402 and then enters the accommodating groove 401. When the limit block 403 completely enters the accommodating groove 401, the partition plate 301 slides downward. When the bottom end of the supporting foot 305 is flush with the pulley 107, at this time, the top end of the connecting plate 302 is flush with the bottom end of the square groove 303. The limit block 403 is reset under the action of the limit spring 402. The limit block 403 jams the partition plate 301 to prevent the partition plate 301 from resetting, so that the supporting foot 305 shares the pressure for the pulley 107.
