Abstract
The utility model discloses a hand-pull valve which comprises a valve body and handle, wherein the handle is connected with a needle inserted in the valve body, the valve body is provided with an air channel opposite the port of an air bottle, the needle is arranged in the air channel and sheathed by a spring, the front end of the needle is opposite the protective membrane of the bottle port, the air channel is opposite the one-way valve, the air outlet of the one-way valve is communicated with an air bubble, an indication sheet is mounted outside the valve body, a connecting groove is provided on the valve body, the indication sheet is connected with the valve body in the type of concave-convex connection, the end of the handle is arranged with a connecting convex at the portion opposite the valve body connecting groove. The utility model can confirm accurate return of handle without indication sheet, to confirm the accurate position of the needle and improve product reliability. And a seal structure is arranged between a suspension arm and the valve body at lower, to protect product structure from incorrect drawing direction.
Description
Technical field
The utility model relates to a kind of water survival articles for use, particularly life saving air bag is inflated the hand valve of usefulness.
Background technique
In survival equipment, the surface of hand valve is connected with the life saving air bag heat seal, drive pricker by handle and puncture gas cylinder, carbon dioxide in the gas cylinder is filled in people's life saving air bag, but existing hand valve is as Fig. 1, shown in 2, have one to connect draw-in groove 12 in valve body 1 outside, be convenient to install indicating piece (not marking among the figure), the rope of handle 2 and handle link passes in indicating piece, and indicating piece plays the role of positioning when using first, but after once finishing using, indicating piece is pulled off, because handle is connected with pricker, can not well locate the needle penetration of just influence thorn, influence the reliability that product uses, in addition, existing hand valve, the side in valve body 1 outside is provided with cantilever 14, and handle 2 is connected with valve body 1 from cantilever 14 downsides, between the valve body 1 of the cantilever 14 in handle 2 outsides and bottom is hollow structure, like this, cause the product high spot unsettled, intensity is too poor, use is easy to distortion, and influence is normally used.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to have overcome above-mentioned shortcoming, provides a kind of use reliability higher hand valve.
The technical scheme in the invention for solving the technical problem is: a kind of hand valve; it comprises valve body; handle; the described handle pricker interior with going deep into valve body is connected; be provided with the air flue relative at described valve inner with the bottleneck of gas cylinder; described pricker is arranged in the air flue; be with spring on the described pricker; the front end of pricker is relative with the protective film of bottleneck; air flue is simultaneously relative with one-way valve; the outlet side of one-way valve is communicated with air bag; in the outside of described valve body one indicating piece is installed; be provided with the connection draw-in groove on described valve body, described indicating piece is connected with described valve body by the convex-concave ways of connecting, and the position relative with valve body connection draw-in groove at the end of described handle is provided with connection bump.
Described hand valve, the side in described valve body outside is provided with cantilever, and described handle is connected with described valve body from described cantilever downside, is enclosed construction between the valve body of cantilever outside the described handle and bottom.
Hand valve of the present utility model, owing to be provided with connection bump in the end of the handle position relative with the valve body connecting groove, after hand valve uses for the first time, after indicating piece drops, the connection bump of handle directly connects with the draw-in groove that is connected of valve body, thereby guarantee that handle is not having proper reset under the situation of indicating piece, guarantee that pricker is in the tram when using next time, improve the use reliability of product.In addition, owing to be designed to enclosed construction between the valve body with cantilever and bottom, strengthen product strength, product is not yielding, and is not fragile, guarantees operational safety.

Embodiment
Shown in Fig. 3-6; hand valve of the present utility model; comprise valve body 1, handle 2; handle 2 is connected with pricker 3 in going deep into valve body 1; be provided with the air flue 11 relative in valve body 1 inside with the bottleneck of gas cylinder 7; pricker 3 is arranged in the air flue 11; be with spring 5 on the pricker 3; be provided with seal ring 4 between the inwall of the rear portion of pricker 3 and air flue 11; the front end of pricker 3 is relative with the protective film of bottleneck, and air flue 11 is simultaneously relative with one-way valve 9, and one-way valve 9 is provided with spring 10; valve body 1 outside is provided with catch 8, and the outlet side of one-way valve 9 is communicated with air bag by the gas transmission road.
One indicating piece 6 is installed in the outside of valve body 1, on valve body 6, be provided with and connect draw-in groove 12, indicating piece 6 is connected with valve body 1 by the convex-concave ways of connecting, at the end of handle 2, the position relative with valve body connecting groove 12 is provided with connection bump 13, after using indicating piece to drop for the first time, the connection bump 13 of handle directly connects with the draw-in groove 12 that is connected of valve body, thereby guarantee that handle 2 is not having proper reset under the situation of indicating piece, guarantee that pricker 3 is in the tram, improve the use reliability of product.
Side in valve body 1 outside is provided with cantilever 14, and handle 2 is connected with valve body 1 from cantilever 14 downsides, is enclosed construction between the top cantilever 14 in handle 2 outsides and lower body 1.This structure strengthens product strength, and product is not yielding, and difficult the damage because of direction of pull is improper guaranteed the product structure reliability.
