Problems solved by technology

[0002] At present, most of the trolley cases on the market have a fixed volume, and the volume cannot be changed according to the number of items carried. If you carry a lot of items during travel, you cannot put them all into the box. If you carry less, it will waste space and is inconvenient to drag.
The usual solution is to set an extra layer on the box through a zipper. When there are fewer items to carry, the extra layer is in a retracted state. Once the amount of carried items exceeds the volume of the box, the extra layer is opened to increase the volume of the box. The extent to which this method can increase the volume is extremely limited, and the thickness of the

Abstract

The invention discloses a volume-adjustable luggage and belongs to the field of suitcases. Two luggage bodies with opened tops and opened bottoms are embedded mutually to form the containing space of the luggage, the upper luggage body can be telescopically pulled out or inserted in the lower luggage body through stretching and contracting of a telescopic type draw bar, and free changing of the volume of the luggage bodies is achieved. An object taking opening of the luggage is formed in the front sides of the luggage bodies through zippers, the containing space is formed by the two luggage bodies, and more objects can be contained; due to the fact that a groove is formed in the inner surface of the lower luggage body, the telescopic draw bar is arranged in the groove so that the space occupied by the draw bar can be reduced, and the layout of the whole luggage bodies is more reasonable; and due to the fact that the luggage bodies are provided with a rail groove and a rail matched with the rail groove, the upper luggage body can be pulled out or inserted in conveniently and rapidly, meanwhile, abrasion to the luggage bodies in the stretching and contracting process of the draw bar can be relieved, and the service life of the box bodies is prolonged.

Description

technical field [0001] The invention belongs to the field of suitcases, in particular to a volume-adjustable trolley case. Background technique [0002] At present, most of the trolley cases on the market have a fixed volume, and the volume cannot be changed according to the number of items carried. If you carry a lot of items during travel, you cannot put them all into the box. If you carry less, it will waste space and is inconvenient to drag. The usual solution is to set an extra layer on the box through a zipper. When there are fewer items to carry, the extra layer is in a retracted state. Once the amount of carried items exceeds the volume of the box, the extra layer is opened to increase the volume of the box. The extent to which this method can increase the volume is extremely limited, and the thickness of the box body increases after opening the extra layer, and the center of gravity is prone to instability when dragging, and it will also affect the appearance of the...
