Traveling wear resistance testing device for draw-bar box

Abstract

The invention discloses a draw-bar box walking wear resistance testing device. The device comprises a bottom plate, wherein limiting plates are fixedly connected to the front end and the rear end of the center of the top of the bottom plate, servo motors are fixedly connected to the two sides of the front face of each limiting plate, and output ends of the servo motors penetrate to the inner sides of the limiting plates and are fixedly connected with walking wear resistance testing rollers; and fixing plates are fixedly connected to the two sides of the top of the bottom plate. Through mutual cooperation of the fixed plate, the box body, the stepping motor, the threaded rod, the threaded block, a movable plate, a push rod, a U-shaped clamping plate, a rotating shaft, a first bearing, a second bearing, a sliding groove, a sliding block and a buffer pad, the advantage of clamping and fixing the draw-bar box is achieved, so the draw-bar box can be effectively clamped and fixed when a walking wear resistance test is performed on the draw-bar box, the draw-bar box is prevented from shaking and falling off, walking wear resistance test accuracy of the draw-bar box is improved, and the use requirement of a user can be met.

Description

technical field [0001] The invention relates to the technical field of trolley case processing, in particular to a walking wear-resistant test device for a trolley case. Background technique [0002] The trolley case refers to a suitcase with a trolley and a roller. It is widely used because of its convenience. It is divided into tubes to facilitate dragging when walking, which greatly reduces the burden. The trolley case can be carried or dragged. The wheels of the trolley case we usually use are basically located at the bottom of the case, and modern people have designed a new form. The trolley case is designed in the shape of a cylinder, and the wheels are completely outsourced on the outside of the case. This roller design makes this trolley case better adapt to different terrains, such as directly pulling the case to go up and down the stairs easily. [0003] When carrying out the wear resistance test of the trolley case, it is necessary to use the wear resistance test...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a walking wear-resistant testing device for a trolley case, which has the advantage of clamping and fixing the trolley case, and solves the problem that the existing wear-resistant testing device does not have the function of clamping and fixing the trolley case. During the walking wear resistance test of the trolley case, it is easy to shake and fall off, resulting in the problem of low accuracy of the walking wear resistance test of the trolley case
