Draw-bar box of being inflated to increase protection function

Abstract

The utility model discloses a draw-bar box capable of being inflated to increase a protection function and belongs to the technical field of travel draw-bar boxes. The draw-bar box is provided with aninflating device, an air bag and the control device by improving and adding structural parts and reasonably connecting and matching all the parts. The improved pull rod has an inflation function andcan inflate the air bag, a user can freely switch between an inflation mode and a pull rod mode through a series of control devices, and air in the air bag can be exhausted at any time according to needs. The user can inflate the draw-bar box according to needs, so that the draw-bar box can better fix and protect the contents of the box and the box body, the original functions of the draw-bar boxare not influenced, and the influence on the original functional characteristics of the draw-bar box, such as volume, space in the box, weight and the like, is very small. The invention solves the problems of fixation when the contents of the traditional draw-bar box are insufficient, the problem that some articles are not suitable for being fixed by an elastic buckle belt, and the problems of collision resistance and extrusion resistance of the box body when a spare space exists in the box body.

Description

【Technical field】 [0001] The invention belongs to the technical field of trolley cases, and in particular relates to a novel trolley case which can be inflated to increase the protection function of the contents of the case and the case body itself. 【Background technique】 [0002] With the continuous and rapid development of the social economy, various styles of trolley cases have almost become necessary items for people to travel. However, most of the trolley cases on the market today have a fixed internal volume. In space, the general solution is to use the compartments installed inside the box and the elastic buckle to fix the items, but the defects of this method include but are not limited to: 1.

[0002] With the continuous and rapid development of the social economy, various styles of trolley cases have almost become necessary items for people to travel. However, most of the trolley cases on the market today have a fixed internal volume. In space, the general solution is to use the compartments installed inside the box and the elastic buckle to fix the items, but the defects of this method include but are not limited to: 1. Some items such as high-end clothing are fixed by the elastic buckle, which will cause Wrinkles, which will reduce the use experience; 2. Some items may not be suitable for fastening with buckles or (and) compartments due to their shape and texture characteristics; 3. After being fixed with buckles or (and) compartments, there are many The space that comes out is still empty, and if it is impacted and squeezed by external force during transportation or storage, the box body is more likely to be damaged
