After the use length adjustment is completed, the state of the two telescopic plates 3 after extension is automatically limited through the transmission self-locking of the threaded rod 602 and the threaded sleeve 601, so as to facilitate the flexible operation and use of the wheelchair ramp.

[0026] The extrusion assembly includes a threaded sleeve 601 fixed on the support plate 101, a threaded rod 602 is threadedly engaged on the threaded sleeve 601, one end of the threaded rod 602 is rotatably connected to the upper end of the transmission plate 401, and a driving pin 603 is fixed to the other end of the threaded rod 602; the guide assembly includes a guide hole 701 opened on the transmission plate 401, a guide rod 702 is slidably connected to the guide hole 701, and the guide rod 702 is fixed to the mounting groove 2;

[0033] It should be noted here that the handle 10 facilitates the picking up and moving of the entire wheelchair ramp.

[0034] Working principle: When the wheelchair ramp is in use, the two groups of support plates 101 are spread apart from each other. After the spread is completed, the driving plate 401 is driven to slide inside the mounting groove 2 through the cooperation between the pushing assembly and the guide assembly. During the sliding process of the driving plate 401, the two inclined grooves 402 interact with the two driving pins 403 respectively, so as to drive the two telescopic plates 3 to move under force. During the movement of the two telescopic plates 3, the two telescopic plates 3 are extended outward on the support plate 101 through the sliding guide effect of the sliding assembly. The use length of the entire wheelchair ramp is adjusted through the extension of the two telescopic plates 3, so that the wheelchair ramp can be used to adapt to slopes of different heights.

[0035] In the process of extending and adjusting the two telescopic plates 3 on the wheelchair ramp, the transmission plate 401 is driven to move by the cooperation between the threaded rod 602 and the threaded sleeve 601 on the push assembly. In the process of the transmission plate 401 moving, the two telescopic plates 3 can be driven to move closer to or away from each other at the same time, so as to quickly and efficiently adjust the use length of the wheelchair ramp. After the use length adjustment is completed, the state of the two telescopic plates 3 after extension is automatically limited by the transmission self-locking of the threaded rod 602 and the threaded sleeve 601, so as to facilitate the flexible operation and use of the wheelchair ramp.

[0036] After the wheelchair ramp is used, the two telescopic plates 3 are driven to contract toward the inside of the mounting slot 2 through transmission. After the contraction is completed, the two support plates 101 are folded to facilitate the carrying and storage of the wheelchair ramp after use.
