Draw-bar box

Abstract

The invention discloses a draw-bar box, and relates to the field of draw-bar boxes. The draw-bar box is provided with a box body and box wheels, the box wheels are distributed at the bottom of the box body, the box body is an integrated box body, the box wheels are all located within the range of the bottom of the integrated box body, the box body is provided with a box cover, the box cover is installed on the side face of the integrated box body in an openable and closable mode, the integrated box body replaces a front box body and a rear box body which are in flexible connection, and the box wheels are arranged at the bottom of the integrated box body, so that when the integrated box body passes through a sunken part of a road surface, the box wheels positioned above the sunken part are limited by the integrated box body and cannot sink into the sunken part, the probability that the box wheels sink into the sunken part is reduced, the dragging stability of the draw-bar box can be effectively improved, and the user experience is improved. As the integrated box body replaces the front box body and the rear box body which are flexibly connected, the problem of high-low dislocation is naturally avoided, and the problem that hinge pieces are damaged due to high-low dislocation of the box bodies is avoided.

Description

technical field [0001] The invention relates to the field of trolley cases, in particular to a trolley case. Background technique [0002] The trolley case is a common tool for people's daily travel, and it has the characteristics of a large number of items and convenient towing. [0003] Most of the trolley cases on the market are generally structured as described in the patent literature of Chinese Patent Publication No. CN206006276U. The case consists of a front case and a rear case, which are connected by hinges and slide fasteners. [0004] The problem with this type of trolley case is that the two pairs of wheels at the bottom of the case correspond to the front case and the rear case respectively. The front case and the rear case are softly connected by zippers and hinges, which causes the trolley case to move Once encountering a road surface with ups and downs in the process, the level of the front box and the rear box is prone to misalignment. For example, there is...

Problems solved by technology

[0004] The problem with this type of trolley case is that the two pairs of wheels at the bottom of the case correspond to the front case and the rear case respectively. The front case and the rear case are softly connected by zippers and hinges, which causes the trolley case to move Once encountering a road surface with ups and downs in the process, the level of the front box and the rear box is prone to misalignment. For example, there is a depression on the road that the trolley box passes. When the front box corresponds to the depression, the front box and the rear box are softly connected. , under the action of gravity, the corresponding box wheels of the front box body will sink into the depression, while the rear box body remains on the original level. In the depression, it increases the bumpy feeling when the trolley case is dragged, which is not conducive to the user experience
