Abstract
The utility model relates to an air pressure gun for a tyre, relating to an air pressure measuring and air filling and discharging device inside various automobile tires. The utility model is composed of an inflation system, a deflating system, a gun body, a pressure meter, and a quick joint component. The operation of the air pressure gun for a tyre can be conveniently finished by a single hand. The utility model has the advantages of simple structure, high reliability, and convenient portability. When the air pressure gun for a tyre carries out measuring for the air pressure of a tyre, only the quick joint component is needed to be connected to the air valve of the tyre, and an air pressure value inside the tyre can be obtained from the pressure meter. When the air pressure value is above or below a standard value, the desired air pressure value can be obtained by controlling the press button of an air filling and discharging system.
Description
The utility model relates to that air pressure in a kind of all kinds of motor tire is measured, filled, bleeding device.
When whether the air pressure of people in measuring all kinds of motor tires reached required standard, the general method that kicks, bludgeons that adopts was evaluated with the experience of daily accumulation.When the air pressure in the necessary differentiation tire, have to the appendix joint is taken off, and load onto compression indicator at valve arrangement, when air pressure was not enough or too high, resetting upward again, the appendix joint put on the air or exits.Because by touch is evaluated air pressure in the tire and whether is reached very science not of standard simply, and measure required multinomial repetitive operation with compression indicator, make the air pressure in the tire be difficult to reach required standard, influence the service life of tire, brought many inconveniences also for simultaneously people's work or life.
The purpose of this utility model is: a kind of above-mentioned shortcoming that overcomes is provided, can measures the air pressure in the tire simultaneously, and the device that fills, exits.
The utility model is by the rifle body, fills, composition such as blow-off system, compression indicator, quick coupling assembly.Air inflator system, compression indicator all with rifle body thread connection; Blow-off system and rifle body adopt thread connection or close fit; Each connection place is all filled out with seal ring, quick coupling assembly and India rubber tube socket, and the other end of India rubber tube is socketed on the rifle body.When the air pressure of tire is measured, the quick coupling assembly need only be connected in the valve nozzle mouth of tire, can obtain the reading of the atmospheric pressure value in the tire from compression indicator.When this atmospheric pressure value is higher or lower than standard value, can obtain required atmospheric pressure value by handling the button of air inflator system or blow-off system.
Characteristics of the present utility model are: easy to operate, one hand can be finished, and is simple in structure, and switching is reliable, easy to carry rapidly.
Accompanying drawing is a main cutaway view of the present utility model, below in conjunction with accompanying drawing action of the present utility model is further described.
Air inflator system of the present utility model is by inflating button (1), charging valve (18), spring (2), seal ring (4), (19), pore plug screw (3) composition.Charging valve (18) can pass through pin or thread connection with inflation button (1).Pore plug screw (3) by thread connection in rifle body (10).Charging valve (18) is a running-fit with rifle body (10).Blow-off system is by venting button (6), threaded connection (21), and spring (8), seal ring (5), spring perch (7) are formed, and spring perch (7) is close fit or thread connection with rifle body (10).Venting button (6) connects or thread connection for pin with threaded connection (21).The quick coupling assembly is by quick coupling (11), valve thimble (17), adaptor union (20) is formed, and the quick coupling assembly is by India rubber tube (12) and rifle body (10) socket, valve thimble (17) and quick coupling (11) are running-fit, with adaptor union (20) be thread connection or close fit.
When on the valve nozzle that quick coupling (11) is screwed in tire, valve thimble (17) backs down the valve of tire, gas is through India rubber tube (12), air flue (15), (14), can on air-pressure gauge (9), demonstrate the numerical value of this air pressure, meanwhile, because the effect of air pressure makes seal ring (5) be pressured state under the boss effect on the threaded connection (21); Boss on charging valve (18) under the effect of spring (2) makes seal ring (19) be pressured state, makes this atmospheric pressure value keep constant.When shown atmospheric pressure value is higher than standard value, can be by pressing venting button (6), threaded connection (21) makes seal ring (5) be the state of not stressing, and unnecessary gas is released by deflation hole (13).When shown atmospheric pressure value is lower than standard value, can link by the India rubber tube of air flue (16) end and the current nipple of external air source, can get source of the gas from the pore on the pore screwed plug (3) whether gas is arranged, then, press inflation button (1), charging valve (18) compression spring (2), make seal ring (19) be free state, and the other end of charging valve (18) makes seal ring (4) be pressured state, the pore of sealing pore plug screw (3), make external air source pass through air flue (16), (15), India rubber tube (12) is added on the tire, can obtain required air pressure from compression indicator (9).
