Abstract

The utility model discloses an air duct, which can realize the human power inflation on the internal tire of the American air valve. The air duct is a plastic short pipe with a 4 to 5 mm external diameter, a 2.5 to 3 mm internal diameter, and the 6 to 9 mm length. Through making use of the air duct, the air valve of the internal tire and the conduit of the inflating pump are tightly connected, and the purpose of the human power inflation can be smoothly realized. The utility model has the advantages of simple structure, easy manufacture, low cost, and convenient usage. The air duct is suitable for all kinds of internal tires of the automobile, the motorcycle, the cross-country bicycle, the boby carrier, or the lifebuoy, etc. Under the condition of being provided with the electricity inflation, the air duct can fundamentally solve the problem of the American air valve that the inflation of the human power inflating pump is difficult.

Description

Airway

The utility model belongs to a kind of inflation accessory; The inflation accessory that particularly belongs to the inner tubes of a tyre such as automobile, motor bike.

The inner tubes of a tyre such as existing automobile, motor bike, mountain bike belong to American valve nozzle more.This valve nozzle does not have under the situation of electric inflatable appliance in the way of travelling, if during with the inflation of artificial Floor Pump, the normal external diameter of chewing because of inner tube valve can't be realized tight joint greater than the internal diameter of Floor Pump conduit, inflates to manpower and causes insurmountable difficulty.Thereby the urgent expectation of numerous driver and crew overcomes this technical barrier that is faced when manpower is inflated.

The purpose of this utility model is to fail the above-mentioned difficulties that overcomes so far at the various inner tubes of a tyre of American valve nozzle when manpower is inflated.Providing a kind of can chew inner tube valve and the tight ventilation flue who connects of Floor Pump conduit, to realize carrying out smoothly the purpose of manpower inflation.

Substance of the present utility model is: design with make a kind of plastic hollow short tube, its external diameter can insert inner tube valve just and chew internal diameter with the Floor Pump conduit, thereby makes the two constitute the tight connection that coincide, the unhelpful leakage when avoiding the manpower inflation.

Fig. 1 is a structural representation of the present utility model;

Ventilation flue shown in Figure 1 is a hollow short tube of selecting the vinyon die cast for use, perhaps select for use intensity, plasticity, resistance to aging all with cooresponding other plastic material die casts of polyethylene; Also can select performance, the satisfactory shaping catheter of specification for use, according to the direct excision forming of length requirement.The concrete specification of conduit is with external diameter 4～5mm, internal diameter 2.5～3mm, and long 6～9mm is advisable.

Using method of the present utility model is: with finger ventilation flue's a end is pushed in the hole that inner tube valve chews, push up on two arms of plunger, then the conduit of Floor Pump inserts on the ventilation flue, and holding screw (end hoop) pine to implementing manpower and inflate with till on the supravasal clamp folder of Floor Pump.

Characteristics of the present utility model are simple in structure, easy to manufacture, low price, the various inner tubes of a tyre such as automobile, motorcycle, mountain bike, perambulator or lifebuoy that are common to easy to use. Fundamentally having solved American valve nozzle is not having in the situation of electricity inflation, a difficult problem of inflating with manual inflator. And after manpower was inflated, wireway needn't take out, and did not affect electricity and inflate.

Claims (2)

1, a kind ofly on the American valve nozzle inner tube of a tyre, realizes the gas filed ventilation flue of manpower, it is characterized in that it is that a kind of external diameter is 4～5mm, internal diameter 2.5～3mm, the plasticity short tube of long 6～9mm.

2,, it is characterized in that this ventilation flue can select the vinyon die cast for use according to the said ventilation flue of claim 1; Also can select all satisfactory plastic pipe excision forming of specification and performance for use.
