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

A kind of backpack of internal airbag

Technical field

The present invention relates to the backpack of a kind of internal airbag.

Background technology

Chinese patent ZL2015206721244 discloses the both shoulders bag of a kind of internal airbag of my invention, and it can be fast Speed inflation, be used for suing and labouring other people or save oneself, it is also possible to the valuables putting into bag are played Anti-bumping protection effect, but actual should In with when valve opened by drop-down slide plate, due to valve soft material, the frictional force between slide plate and valve is very big, and slide plate can carry Mouth of taking offence moves together, and valve is difficult to open ejection, it addition, be integrative-structure for closing the upper cover of valve, and upper cover groove The track of sidewall is difficult to processing when injection, relatively costly.

Summary of the invention

The technical problem to be solved in the present invention is to provide the backpack of a kind of internal airbag, and it can make the valve of air bag Also being easy to when slide plate is drop-down eject, additionally the track of upper cover recess sidewall is easy to be processed to form.

For solving the problems referred to above, the backpack of a kind of internal airbag of the present invention, it includes knapsack body, is arranged on knapsack U-shaped air bag within interlayer, the valve of air bag stretches out the back side of knapsack body and is positioned at the top at the knapsack body back side, described gas Having one for opening and close the locking device of valve on mouth, described locking device includes that one is positioned at inside the knapsack body back side Base plate, the upper cover that is positioned at knapsack body exterior corresponding with base plate, upper cover is through the fabric at the knapsack body back side and base plate Connecting by screw is fixing, there is a longitudinal fluting on the surface of upper cover, and groove is stamped a slide plate, and two sidewalls of groove are respectively arranged with Article one, slideway, the dual-side of slide plate stretches into slideway can in slideway slidably, and a circular hole is arranged at the bottom of groove, the gas of air bag Mouth stretches out from bottom portion of groove circular hole, wherein, is provided above a block pressur plate, the both sides of pressing plate one end and the sidewall of groove at groove Hinged.

Use said structure, when valve closed by needs, first pass through pressing plate and push down valve and go up push skateboard again and push down pressing plate, i.e. Valve can be closed；When needing to open valve, owing to the friction between slide plate and pressing plate is less, pressing plate also and cuts with scissors between recess sidewall Connecing, so, when slide plate is drop-down, pressing plate will not slide together with slide plate, is therefore easy to slip off, after slide plate slips off from pressing plate Valve pressing plate of automatically upspringing is opened, and it is the easiest to open.

It is in the one side that pressing plate contacts, have at least one horizontal convex tendon with valve as improving further of invention.This Sample, can push down valve by convex tendon, and lifting surface area is little, only needs less pressure just can complete to seal.

As a further improvement on the present invention, described upper cover comprises a housing and a dividing plate covering in housing, described Groove is positioned on dividing plate, and the both sides of described groove top and the inner surface of housing leave gap, forms two for slide plate slides Track.

Use this structure, the track of upper cover recess sidewall to be surrounded by the dividing plate in housing and housing, process ten Partial volume is easy.

Detailed description of the invention

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, the backpack of a kind of internal airbag of the present invention, it includes knapsack Body 1, being arranged on the U-shaped air bag 2 within knapsack interlayer, the valve 3 of air bag 2 stretches out the back side of knapsack body 1 and is positioned at knapsack The top at body 1 back side, described valve 3 has one for opening and close the locking device of valve 3, and described locking device includes 4, upper cover of being positioned at knapsack body 1 outside corresponding with base plate 4 of one base plate being positioned within knapsack body 1 back side, upper cover Fabric through knapsack body 1 back side is connected by screw is fixing with base plate 4, and there are a longitudinal fluting 5, groove 5 in the surface of upper cover On be stamped a slide plate 6, two sidewalls of groove 5 are respectively arranged with a slideway 7, the dual-side of slide plate 6 stretches into slideway 7 can be at slideway In 7 slidably, a circular hole 12 is arranged at the bottom of groove 5, and the valve 3 of air bag 2 stretches out from groove 5 bottom circular aperture 12, wherein, every Being additionally provided with a block pressur plate 8 on the groove 5 of plate 11, the both sides of pressing plate 8 one end are side walls hinged with groove 5.

Use said structure, when valve 3 closed by needs, first pass through pressing plate 8 and push down valve 3 and go up push skateboard 6 again and push down pressure Plate 8, can close valve 3；When needing to open valve 3, owing to the friction between slide plate 6 and pressing plate 8 is less, pressing plate 8 is also with recessed Between groove 5 sidewall hinged, so, when slide plate 6 is drop-down, pressing plate 8 will not slide together with slide plate 6, is therefore easy to slip off, works as cunning Plate 6 slips off rear valve 3 pressing plate 8 of automatically upspringing from pressing plate 8 and opens, and it is very easy to open, and contacts with valve 3 at pressing plate 8 Having at least one horizontal convex tendon 9 on Yi Mian, as such, it is possible to push down valve 3 by convex tendon 9, lifting surface area is little, only needs less pressure Power just can complete to seal；Described upper cover comprises a housing 10 and a dividing plate covered in housing 10 11, described groove 5 On dividing plate 11, the described both sides on groove 5 top and the inner surface of housing 10 leave gap, form two for slide plate 6 slip Track 7, the track 7 of upper cover recess sidewall is surrounded by the dividing plate 11 in housing 10 and housing 10, and it is the easiest that processing is got up.
