Abstract

The utility model relates to an air pipe device of an inflator carried on vehicle, which is characterized in that a butting and combining rubber ring is sheathed and hooped at the end head of a hollow core 2 which penetrates through an air nozzle spiral sleeve 3 and is combined with a connecting screw 4 in a screw mode. The other end of the connecting screw is screwed with a back spiral sleeve 9. A leak preventing ring 5, a tension spring 6, a jogged valve pipe 7 and a valve pipe rubber ring 8 are respectively clamped and sheathed between the connecting screw and the back spiral sleeve, and an air pipe 11 is sheathed on the back spiral sleeve 9 and is tightly hooped by a hooping ring 10. Air is filled and pressure is released through a same pipe body, and the utility model has air filling and exhaust functions. When a tire is inflated, or air pressure is beyond saturation, the air pipe does not need to be discharged, and the pressure can be quickly released to standard values. The utility model prevents an air nozzle core and an operator's fingernails being damaged, and accelerates the pressure relief speed.

Description

A kind of tracheae device with the car charging blower

The utility model relates to mechanical, particularly a kind of tracheae device with the car charging blower.

At present middle-size and small-size with the electric machine of car portable type, the tracheae assembly that is connected with, all with check configuration, shown in accompanying drawing 1 and accompanying drawing 2, its structural constituent mainly is by supporting rubber alloy circle (A1), hollow core (A2), valve swivel nut (A3), banding circle (A4) and tracheae elements such as (A5) constitute, wherein tracheae assembly (A10) is for being roughly when inflation in inflation of tire principle and the operation, earlier the cranked tire valve cap is taken off, be screwed together on the external thread sleeve of cranked tire valve with valve swivel nut (A3), at this moment, locking of valve swivel nut (A3) promptly passed hollow core (A2) forward simultaneously, directly be pressed on the gaseous core in the cranked tire valve, and support rubber alloy circle (A1) with the densification locate mode by the place ahead, the gaseous core pushing is produced the state of opening, and the pressurized air that the charging blower piston operation is caused, promptly, use for inflation of tire via the conveying of tracheae (A5); In gas replenishment process, might be because of external factor or carelessness arranged slightly, promptly cause inflation standard too high (charging blower all is furnished with compression indicator and can supplies to inspect), will recover the standard value of tire pressure this moment, the air of will releasing, have only tracheae assembly (A10) is pulled out from cranked tire valve, sting the mouth gaseous core of calming the anger with finger tip shape foreign matter, the tire compressed air is discharged, reduce tire pressure, this operation is not only required great effort, and at tracheae assembly (A10) after pulling out on the tire, the i.e. loss of pressure table function of inspecting simultaneously, thus can only be approximately disappointing in operation, certainly will cause the tire pressure too much or very few phenomenon of releasing, if lose heart too much, cause the tire pressure deficiency, need again inflation once more, if it is very few to lose heart, then tire pressure is still too high, necessity causes driving a vehicle dangerous, cause a hidden trouble, secondly easily cause cranked tire valve breakage or operator's finger nail injured, and the multiple puzzlement that causes temporal waste and implement.

The purpose of this utility model is exactly the shortcoming that exists with car portable type charging blower tracheae assembly at above-mentioned, a kind of tracheae device with the car charging blower is provided, it is a mode in simple operation, can reach inflation and the beidirectional function of losing heart, promptly need not pull out under the condition of unloading tracheae, can tire pressure reached and cause standard value.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of tracheae device with the car charging blower is provided, it is by one supporting rubber alloy circle, hollow core, valve swivel nut, accepting elements such as spiral shell, leak-stopping circle, tensile spring, embeded valve tube, rubber ring of valve tube, rear thread sleeve, banding circle and tracheae and constituted, wherein cooperatively interact down to accept elements such as spiral shell, tensile spring, embeded valve tube, rubber ring of valve tube and rear thread sleeve, constituting with spring power is the two way valve structure of characteristic; Under normal circumstances, this spring power valve is specialized in the inflation of tire operation and is implemented to use, when the need pressure release for being in closing state, then can impose the simplest and easy tracheae of passing forward, after making embeded valve tube displacement forward, promptly form opening, make the air of tool pressure, import rear thread sleeve via hollow core fast, and discharge by its uropore, reach the purpose of releasing, not only convenient, but also safely, fast and accurately.
