Wear-resistant backpack

Technical Field

The utility model discloses an article for daily use, and particularly relates to a wear-resistant backpack.

Background

A backpack is a bag carried on the back, the materials of the backpack are diversified, and fashionable trends are led by suitcases with the textures of genuine leather, plastic materials, terylene, canvas, nylon, cotton, hemp and the like. In the period of more and more listing the personality, various styles such as conciseness, vintage, cartoon and the like also meet the requirement of fashion people for developing the personality from different sides, and the style is also expanded from the traditional business bag, schoolbag and traveling bag to the pen bag, the change purse, the small perfume bag and the like.

When going out in daily life, valuables such as purses and the like can be put into the backpack, because the traditional backpack is not equipped with anti-theft performance, and the thieves can steal the belongings in the backpack only by unzipping the zipper, the zipper is easily unzipped by the thieves when the thieves are not noticed on public places such as buses, and the thieves can steal the valuables

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to solve the above mentioned problems and to provide a wear resistant backpack.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a wear-resisting knapsack, includes knapsack body, baldric and back panel, the zip fastener has been sewed up to the knapsack body, the zip fastener passes through the pull head and seals, the knapsack body is equipped with the stay cord with pull head fixed connection, the inside rubber tube that holds the stay cord and pass that is equipped with of knapsack body, back panel internal rotation is connected with the rotation piece of taut stay cord, be equipped with the restriction on the rotation piece and rotate the stop gear that the piece revolved.

Through adopting above-mentioned technical scheme, when the user went on a journey and carries this knapsack, with pull head and zip fastener with the knapsack body closure back, and will rotate the piece and rotate and drive the stay cord winding then tighten up the stay cord and make the stay cord be in the state of straining this moment after rotating the piece, then can't stimulate the pull head to open the zip fastener because of the fixed of stay cord this moment, then can avoid the thief to open the zip fastener and steal this internal article of knapsack this moment when carrying on the back the backpack.

Preferably, the limiting mechanism comprises a pressing part fixedly connected with the rotating part, the rotating part is sleeved with a fixing part, the fixing part is provided with a limiting block abutted against the pressing part, and a spring is arranged between the limiting block and the fixing part.

Through adopting above-mentioned technical scheme, change a corotation and can will make the holding-on part promote stopper and compression spring, and rotate a gyration stopper and reset then can restrict the holding-on part gyration and play the restriction and rotate a state that can only one-way pivoted, and then can avoid rotating the piece and lead to the gyration condition because of the pulling force of stay cord.

Preferably, the limiting block is provided with a pressing surface which is abutted against the pressing piece and presses the limiting block to move downwards, and one side of the limiting block, which is far away from the pressing surface, is provided with a limiting surface which limits the rotation of the pressing piece.

By adopting the technical scheme, the pressing piece can push the limiting block along the inclined plane when the rotating piece rotates forwards due to the fact that the pressing surface is the inclined plane, and the limiting surface is the vertical surface when the rotating piece rotates, so that the limiting block and the pressing piece are limited mutually along the limiting surface to avoid the effect of rotating the rotating piece.
