Detailed Description

Embodiments of the present utility model are described in detail below.

1-2, the backpack comprising a first portion having an opening at one end and a second portion connected to the first portion for closing the opening, the quick opening and closing structure being disposed between the first portion and the second portion; the combination assembly comprises a fixing piece and a combination piece, wherein the fixing piece is fixed on the first part, the combination piece is fixed on the second part through an elastic piece, the combination piece is connected with the fixing piece at a first position, the elastic piece is in a deformation state, and after the combination piece is disconnected with the fixing piece, the combination piece is dislocated with the fixing piece under the action of the elastic piece.

The fixing structure which is matched with each other is arranged between the combining piece and the fixing piece, so that the combining piece and the fixing piece can be kept connected with each other at the first position, and the fixing structure can be a hook structure, a buckle structure, a sticking buckle structure and the like. When the combining piece and the fixing piece are connected with each other, the elastic piece generates elastic deformation, after the combining piece and the fixing piece are separated from each other, the restoring force of the elastic piece drives the combining piece to leave the first position, and the fixing piece is kept unchanged at the position of the second part of the backpack, so that the combining piece and the fixing piece are misplaced with each other, and the combining piece and the fixing piece are ensured to be separated from each other to avoid the error combination of the combining piece and the fixing piece.

As a preferred scheme, the quick opening and closing structure comprises a hook component and an elastic piece, wherein the hook component comprises a hook 3 and a connecting buckle 4, the connecting buckle 4 is fixed on the first part, the hook 3 is fixed on the second part through the elastic piece, and the hook 3 is in hooking fit with the connecting buckle 4. The fixing structure between the hook and the connecting buckle is simple, and the connection state switching between the hook and the connecting buckle can be realized through one action, so that the switching of the opening and closing states of the backpack is realized.

In the structure, the connecting buckle 4 is connected with the first part of the knapsack, and the hook 3 is connected with the second part of the knapsack, so that the switching of the opening and closing states of the knapsack can be realized through the cooperation of the connecting buckle 4 and the hook 3. The hook 3 is connected with the elastic piece, the elastic piece enables the hook 3 to be in hooking connection with the connecting buckle 4, and the hook 3 is pulled to be separated from the connection with the connecting buckle 4, so that the switching of the opening and closing states of the backpack is realized. In the structure, as the hook 3 is connected with the elastic piece, the quick separation and combination of the hook 3 and the connecting buckle 4 serving as a hanging point are achieved by utilizing the elasticity of the elastic piece, and the operation is simple.

In other embodiments, the connection structure between the fixing member and the combining member may also have a fastening structure, a sticking buckle structure, or the like.

Preferably, the elastic member comprises an elastic webbing 1. One end of the hook 3 is provided with a hole for the penetration of the elastic braid 1, the elastic braid penetrates through the hole to be connected with the hook, and the other end of the hook 3 is bent to form a hooking part. The elastic braid is adopted as an elastic piece, and the fabric is soft and can avoid damaging the knapsack.

In a preferred embodiment, the elastic member further comprises a positioning webbing 2, the positioning webbing 2 being located between the elastic webbing 1 on both sides, the length of the positioning webbing 2 being greater than the length of the elastic webbing 1, the elongation length of the elastic webbing 1 being limited by the length of the positioning webbing 2. The above arrangement ensures the scalability of the whole structure of the elastic member by the elastic webbing 1, and the positioning webbing 2 is provided to prevent the excessive stretching of the hook 3.
