Abstract

The utility model relates to a portable air valve assembly which is designed for a special air charging connection of an air needle type valve of a tyre. The utility model comprises a separate type convex air charging cap, a key ring and an assembly body. The assembly body is provided with a hole, and the convex post of the separate type convex air charging cap is fixed in the hole. Therefore, the air charging cap and the assembly body are integration to carry. When portable air valve assembly is used, the valve can be conveniently taken off for inflation. The utility model can be widely used for air needle type valve of the tyre of an electric bicycle, a mountain biking, a motorcycle, etc.

Description

Portable gas is chewed assembly

The utility model relates to the air needle type charge valve of tire, is a kind of inflation interface specifically.

At present, the charging valve of vehicle tyre mainly contains two kinds of valve inside formula and air needle types.And the air needle type valve is because good sealing effect, long service life and being widely used on the tire of mountain bike, Electrical Bicycle, motor bike etc., but when using common Floor Pump to inflate, need connect and use special purpose interface, because its size is bigger, need during inflation to change at any time, make troubles to the user.My patent No. is the patent of 95235304.0 " a kind of novel tire charge valve ", interface is inflated in special use become a kind of split type convex inflation cap, it is made up of spool and pressure cap, spool is through in the pressure cap, there is groove both sides, spool lower end, packing seal is arranged in pressure cap at the spool bottom, and during use, pressure cap is rotatably connected in outside the valve pocket of air needle type valve.This inflation interface one is that inflation laborsaving two is that volume is little, still has many inconvenience but carry.

The purpose of this utility model is a kind of portable inflation cap assembly of design.

The purpose of this utility model is achieved like this, to be used for the gas filed split type convex inflation of air needle type valve cap is installed on gas and chews assembly, this assembly is made up of split type convex inflation cap, key bow, module body, key bow is connected with module body, porose on the module body, be provided with columnar projections in the hole, its diameter is identical with inflation cap pressure cap internal diameter, and split type convex inflation cap is satisfied with on the columnar projections with pressure cap.

Accompanying drawing is a scheme drawing of the present utility model.

Now in conjunction with the accompanying drawings the utility model is done to describe in detail.This assembly key bow can be made of metal, and module body 2 is made of plastics, make by organism glass with the transparent briquetting module body one or the iron chains embedding 3, but centre iron chains embedding trade mark or pattern.Porose 4 on the module body, hole 4 can be square hole, and the columnar projections 8 on it can have outside thread, and its pitch is identical with inflation cap pressure cap 7 negative thread pitch, is 8V ₁The inflation cap is by spool 5, and valve pad 6 and pressure cap 7 are formed.When need are pacified the inflation cap in the module body hole, earlier spool is pressed in the pressure cap, paperback is in the main body square hole, push pressure cap to columnar projections again, make the pressure cap inner hole sleeve on columnar projections, and eject spool, if on the columnar projections outside thread is arranged, then must be spun on the columnar projections with the pressure cap negative thread.When need with the inflation cap when assembly takes off, pressure cap is oppositely released (or back-outing) to the projection direction, spool is pressed in the pressure cap, laterally release again and get final product.This gas is chewed assembly and can be fixed in the inflation cap on the assembly, is convenient to carry, and both can take off the inflation that is used for the air needle type valve at any time, the both artistic and practical art work of can yet be regarded as again.

Claims

1. a portable gas is chewed assembly, it is characterized in that it is made up of split type convex inflation cap, key bow (1), module body (2), key bow is connected with module body, porose on the module body (4), be provided with columnar projections (8) in the hole, its diameter is identical with inflation cap pressure cap (7) internal diameter, and split type convex inflation cap is satisfied with on the columnar projections with pressure cap.
