Self-locking reinforced carrying handle for luggage and self-locking method of self-locking reinforced carrying handle

Abstract

The invention discloses a self-locking reinforced carrying handle for a luggage and a self-locking method thereof. The carrying handle comprises a carrying handle body, movable hook assemblies and a fixed hook assembly, the carrying handle body is arranged on the outer side of a first luggage shell of the luggage, the movable hook assemblies are arranged at the two ends of the carrying handle body respectively, and the movable hook assemblies extend into the inner side of the first luggage shell; two groups of fixed hook assemblies are arranged on the inner side of a second luggage shell of the luggage, and each group of movable hook assemblies is matched with one group of fixed hook assemblies. According to the self-locking method, when the carrying handle body is lifted and pulled, the distance between the two ends of the carrying handle body is shortened due to the fact that the carrying handle body arches towards the center, and the movable hook assemblies at the two ends are driven to be close to each other till the movable hook assemblies are meshed with the corresponding fixed hook assemblies to form a self-locking structure. Otherwise, the self-locking structure is released. A self-locking stress structure can be formed in the luggage shell, the stress of the luggage shell and the frame is reduced, the user operation is easy and convenient, the self-locking structure is arranged in the luggage shell, and the attractiveness of the overall structure of the luggage can be effectively improved.

Description

technical field [0001] The invention relates to the field of bags, in particular to a self-locking reinforced handle for bags and a self-locking method thereof. Background technique [0002] In the field of bags, in order to facilitate the use of bags, handles are generally provided on the top and sides of bags (especially trolley cases), such as figure 1 As shown, the handle body 1 is generally locked and installed together with the case shell and the frame. During the use of the case, the user often needs to lift or put down the case through the handle. It will be repeatedly pulled by the handle. In the manufacture of luggage, no matter whether the luggage is made of woven material, plastic material or metal material, due to the weight of the luggage and the limitation of manufacturing cost, it is generally not to choose a very thick material for the manufacture of the case shell, which makes the overall strength of the case shell relatively high. Weak, and the area that...

Problems solved by technology

However, this method is likely to have the following defects in practical application: (1) the cost of the case is high, because the lock part is a relatively precise part in each component of the case, its structure is more complicated, and the cost is also higher, so the cost of the case is increased. Manufacturing cost; at the same time, due to the relatively precise structure of the lock parts, repeated debugging is required during production and assembly to ensure its good functionality. Therefore, increasing the number of lock parts on the luggage will also increase the labor cost of luggage manufacturing; (2) Luggage When the number of locking parts is large, the user needs to repeatedly open and close each locking part in different positions during the use of the luggage, which is not convenient for the user to use the luggage and the user experience is poor; (3) multiple locking parts are exposed to the luggage On the outer wall of the bag, it is easy to cause the appearance of the bag to be not simple enough and affect the aesthetics of the bag
