High-strength compression-resistant draw-bar box

Abstract

The invention discloses a high-strength compression-resistant draw-bar box, which comprises a box body, and a draw bar body is fixedly mounted at the top of the front surface of the box body. According to the invention, a shell, a buffer box, a first spring, a moving plate, a moving column, a buffer plate, moving wheels, a fixed plate, a second spring, a first sliding groove, a third spring, a first sliding block, a second sliding groove, a second sliding block, a high-strength compression-resistant layer, a polyphenylene sulfide plastic layer, a polyimide plastic layer, a waterproof layer, an acrylic resin coating layer and a vinyl resin coating layer are arranged and cooperate with each other; the draw-bar box has the advantages that the strength and compression resistance, the waterproof performance and the roller buffering performance of the draw-bar box are improved, so that when the draw-bar box is extruded, the strength and compression resistance of the draw-bar box can be effectively improved, the draw-bar box is prevented from being extruded and damaged, the waterproof performance of the draw-bar box can be improved, meanwhile, the rollers of the draw-bar box can be effectively subjected to elastic buffering and damping, so that the rollers of the draw-bar box are prevented from being damaged by vibration.

Description

technical field [0001] The invention relates to the technical field of trolley cases, in particular to a high-strength compression-resistant 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 adaptable to different terrains. For example, you can easily go up and down the stairs by directly pulling the case. The main materials are cloth boxes, ABS hard boxes, leather boxes, PC, etc., and the usability is divided into three c...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength compression-resistant trolley case, which has the advantages of improving the strength and compression resistance of the trolley case, waterproof performance and roller buffer performance, and solves the problem that the existing trolley case has poor strength and compression resistance. As a result, the trolley case is prone to extrusion damage when it is squeezed, and the waterproof performance of the trolley case is poor. At the same time, the cushioning performance of the rollers of the trolley case is poor, so that when the trolley case is pushed on uneven ground, the rollers are prone to vibration damage. question
