Carrier capable of climbing stairs

Abstract

The invention provides a carrier capable of climbing stairs. The carrier comprises a carrier frame, a control main body, a moving main body and a supporting main body, the carrier frame comprises a pair of frame rods, a rotating shaft and a bracket, the two ends of the rotating shaft are fixedly connected to the inner walls of the rear portions of the frame rods, and roller shafts are fixedly connected with the front ends of the frame rods; the lower end of the bracket is fixedly connected with the upper walls of the roller shafts, the frame rods, the rotating shaft, the bracket and the rollershafts are fixedly connected into a whole, the control main body comprises a first handle, a pair of cushion blocks and a sliding ring, the front end of the first handle is fixedly connected with theouter walls of the two ends of the connecting rod, the cushion blocks are symmetrically and fixedly connected with the outer walls, deviating from the first handle, of the two ends of the connectingrod, and the first handle, the cushion blocks and the connecting rod are fixedly connected into a whole. The resistance in flat ground movement can be reduced, a user can have a rest conveniently at any time, and the use requirement is better met.

Description

technical field [0001] The invention relates to the technical field of stair-climbing truck equipment, in particular to a stair-climbing truck. Background technique [0002] The moving wheels of common stair-climbing trucks are usually provided with three pairs, and a group of three forms triangular rollers. Four wheels need to be in contact with the ground at the same time, which increases its movement resistance and cannot be as light as a flat truck, which causes the problem of increased resistance. At the same time, most of the existing trucks that can climb stairs need to move the car body when resting on the spot Putting it down completely, it is inconvenient for the user to take a break halfway, so a device that can solve the above problems is urgently needed. Contents of the invention [0003] The purpose of the present invention is to provide a stair-climbing transport vehicle to solve the problems raised in the above-mentioned background technology. [0004] In...

AI Technical Summary

Problems solved by technology

[0002] Common stair-climbable trucks usually have three pairs of moving wheels, of which a group of three forms triangular rollers. When the device moves on flat ground, the two wheels make rolling contact with the ground. Four wheels need to be in contact with the ground at the same time, which increases its movement resistance
