In the figure: 1. the lifting device comprises a bottom plate, 2, a lifter, 201, a motor, 202, screws, 203, a sleeve plate, 204, a telescopic bracket, 3, a chute, 301, a slideway, 4, a top plate, 5, a long groove, 6, a straight plate, 7 and a telescopic ladder.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

please refer to fig. 1-4: the lifter 2 can adopt the scissor lift, motor 201 selects for servo motor model according to the user demand, motor 201's output and screw rod 202's left side looks rigid coupling, screw rod 202's outer wall threaded connection bushing 203, bushing 203's outside rotates with telescopic bracket 204's inboard bottom right-hand member and links to each other, telescopic bracket 204 inboard bottom atress rotates through bushing 203 outside round pin axle, telescopic bracket 204's outer wall bottom is laminated with spout 3's inner wall mutually, telescopic bracket 204's bottom left side rotates with spout 3's inner wall and links to each other, telescopic bracket 204 bottom left side atress rotates through spout 3 inner wall round pin axle. The motor 201 and the screw 202 can be detachably connected, and the extension of the telescopic ladder 7 can be realized by rotating the screw 202 by external equipment without power supply.

The upper plate 4 is provided with a long groove 5 at the lower part of the front side and the rear side, the inner wall of the long groove 5 is connected with the top of the telescopic bracket 204 in a sliding manner, the top of the telescopic bracket 204 is stressed to slide left and right through the inner wall of the long groove 5, the front side and the rear side of the top of the bottom plate 1 are provided with a sliding groove 3 respectively, the bottom of the outer wall of the telescopic ladder 7 is rotationally connected with the right side slot of the bottom plate 1, and the bottom of the outer wall of the telescopic ladder 7 is stressed to rotate through a pin shaft in the right side slot of the bottom plate 1.
