Retractable universal wheel draw-bar box

Abstract

A retractable universal wheel draw-bar box comprises a box body and universal wheels, a mounting base is arranged at the bottom of the box body, symmetrical supporting legs and clamping grooves are arranged on the two sides of the bottom face of the mounting base, a containing cavity is formed between the supporting legs in the length direction of the mounting base, and clamping pins are arranged on the mounting base on the outer side of the containing cavity, deflection plates are arranged between the supporting legs in the width direction of the installation base, one side edge of each deflection plate is rotationally connected with the corresponding supporting leg, the two ends of the other side edge of each deflection plate are clamped with the clamping pins, the universal wheels are perpendicularly installed in the middle of the surface of one side of each deflection plate and matched with the containing cavity, and symmetrical elastic clamping jaws are arranged on the surface of the other side of each deflection plate and matched with the clamping grooves, the deflection plates rotate around the supporting feet, the universal wheels are fed into or rotated out of the containing cavities, the elastic clamping pins and the elastic clamping jaws are used for fixing, the box body is convenient to move, meanwhile, the size of the box body is reduced, the box body is convenient to place in a centralized mode, space is saved, potential safety hazards are reduced, and the trolley case can be used in different scenes.

Description

technical field [0001] The invention belongs to the field of leather goods and bags, in particular to a trolley case with drawable universal wheels. Background technique [0002] The trolley case refers to a suitcase with a pull rod and rollers. In daily life and work, the luggage is placed in the case, and the case can be moved conveniently and quickly through the pull rod without affecting people's travel, saving labor and worry. It has the characteristics of storage and portability, and is widely used. In the development process of luggage, there were wooden boxes and portable suitcases in the early days, and later developed into trolley-type fixed wheel boxes, and then to fixed multi-directional universal wheel trolley boxes that are widely used today. The wheeled trolley case can be dragged and pushed horizontally, and the direction can be adjusted at any time, so it is more popular with the general public and has a high market share.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the trolley case is placed on the way of travel, it is generally placed in a standing or flat manner in the car and high-speed rail. Because of the universal wheels fixed and installed vertically, it takes up a lot of space when placed standing and is prone to accidents. Rolling, causing potential safety hazards, the protruding universal wheels hinder each other when laying flat, which is not convenient for the centralized placement of trolley cases
