The four telescopic plates 12 are all slidably equipped with inclined sliding rods 10, and the tops of the four inclined sliding rods 10 are welded with sliding blocks 20. The sliding blocks 20 are slidably connected to the inside of the moving grooves 21. The tops of the four support plates 7 are movably hinged with two telescopic shells 28, and the telescopic shells 28 are slidably equipped with triangular support rods 8. One end of the triangular support rod 8 is movably hinged to one side of the base 1. Through the arrangement of structures such as the support plate 7 and the triangular support rod 8, the rotation of the disc 24 drives the connecting rod 18 to do reciprocating motion, and the movement drives the telescopic plate 12 to do telescopic motion, so that the support plate 7 can extend out of the base 1, thereby supporting it on the ground, and then through the principle of stability of the triangular support rod 8, the support plate 7 is more stable when supporting the ground. The large-area support plate can significantly expand the support area of ​​the bottom of the lifting platform, increase the contact surface with the ground, and can effectively prevent the lifting platform from shaking or tilting during the lifting process, so that the elevator has better stability.

[0029] like Figure 2-Figure 5 As shown, a square groove 22 is formed on the top of the base 1 , and the connecting plate 4 is slidably connected inside the square groove 22 .

[0034] The specific implementation principle of this embodiment is as follows: the lifting frame 5 starts to rise through the start of the hydraulic rod, driving the sliding rod 3 to slide on the sliding plate 2, thereby driving the connecting plate 4 to start moving, and then the rack plate 15 starts to move, the rack plate 15 and the driven gear 16 are meshed, and the driven gear 16 and the driving gear 17 are meshed, so that the rack plate 15 drives the driven gear 16 to rotate, the driven gear 16 drives the driving gear 17 to rotate, and the driving gear 17 drives the driving shaft 13 to rotate, and the disk 24 on the outer circumference of the driving shaft 13 rotates accordingly, and the thrust of the rotation of the disk 24 drives the connecting rod 18 to move back and forth, thereby realizing the automatic extension and retraction of the support plate 7, and the movement of the telescopic plate 12 drives the inclined sliding rod 10 and the sliding block 20 to slide up and down in the inclined sliding block 9, so that the support plate 7 can fit the ground more closely, on the contrary, when the telescopic plate 12 is retracted, the inclined sliding rod 20 and the inclined sliding block 9 slide back, so that the support plate 7 is retracted to the base 1 and no longer fits the ground, thereby not affecting the free movement of the entire lift.

[0035] Example 2

Through the arrangement of structures such as the maintenance door 25 and the air permeable plate 27, when the lifting platform is in operation, heat will be generated inside the base 1, and the air permeable plate 27 can provide good heat dissipation and ventilation effects. The installation of the maintenance door 25 makes the lifting platform easier to maintain and service, and can promptly discover and solve potential problems, making maintenance and inspection more convenient.

[0037] The specific implementation principle of this embodiment is as follows: the operator can open the door lock and open the maintenance door 25 by rotating the pin shaft, thereby entering the interior of the elevator to perform maintenance, cleaning or replacement of parts. When the elevator is running, the heat generated by the internal components of the base 1 is discharged through the ventilation holes of the air permeable plate 27, achieving the effect of heat dissipation and ventilation.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
