[0002] Chinese patent ZL2015206721244 discloses a shoulder bag with a built-in airbag invented by me. It can be quickly inflated for rescuing others or self-rescue, and can also protect valuables put in the bag from collisions. However, in practical applications When pulling down the slide plate to open the valve, due to the soft material of the valve, the friction between the slide plate and the valve is very large, the slide will drive the valve to move together, and the valve is difficult to open and eject. In addition, the upper part used to close the valve The cover is a one-piece structure, and the track on the side wall of the upper cover groove is difficult to process during injection molding, and the cost is high

Abstract

The invention discloses a backpack internally provided with an air bag. The backpack comprises a backpack body and the U-shaped air bag installed in a backpack interlayer. An air nozzle of the air bag extends out of the backpack and is located at the upper portion of the back face of the backpack body. An upper cover of an air nozzle closing device is composed of a shell and a separation board covered with the shell. A groove is located in the separation board. Gaps are reserved between the two sides of the top end of the groove and the inner surface of the shell, and two rails allowing a sliding board to slide are formed. A pressing board is further arranged above the groove. The two sides of one end of the pressing board are hinged to the side wall of the groove. The face, making contact with the air nozzle, of the pressing board is provided with at least one transverse protruding rib. When the air nozzle needs to be closed, the air nozzle is pressed through the pressing board firstly, then the sliding board is pushed upwards to press the pressing board, and therefore the air nozzle can be closed. When the air nozzle needs to be opened, the sliding board is pulled downwards, the air nozzle can automatically pop up, the pressing board is opened, and the air nozzle is quite easy to open.

Description

technical field [0001] The invention relates to a backpack with a built-in airbag. Background technique [0002] Chinese patent ZL2015206721244 discloses a shoulder bag with a built-in airbag invented by me, which can be quickly inflated for rescuing others or self-rescue, and can also protect valuables placed in the bag from collisions, but in practical applications When pulling down the slide plate to open the valve, due to the soft material of the valve, the friction between the slide and the valve is very large, the slide will drive the valve to move together, and the valve is difficult to open and eject. In addition, the upper part used to close the valve The cover is a one-piece structure, and the track on the side wall of the groove of the upper cover is difficult to process during injection molding, and the cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a backpack with a built-i...
