Ring the tire life-span.
Air pressure is the gate of vitality of tire, the too high and too low service life that can all shorten tire.Air pressure is too low to become carcass
Shape increases, and breach easily occurs in sidewall, while produces flexion motion, causes excessive heating, promotes ageing of rubber, and casing ply is tired
Labor, cord fracture, and can also increase tire-contact area, accelerate shoulder wear.Air pressure is too high, can make tyre cord by excessive
Extension deformation, carcass tension declines, and makes the load increase that automobile is subject under steam, in case of impact can produce implosion and quick-fried
It is broken, while air pressure is too high can also accelerate crown to wear, and make resistance to roll hydraulic performance decline.
The instrument of measurement tire pressure common are tire pressure monitoring system and hand-held tire pressure table.Tire pressure monitoring system be it is existing more
Product of the future, tire pressure can be monitored in real time, and data embodiment is very directly perceived, but its function is single, fault rate is high, and price
It is expensive；Hand-held tire pressure table is easy to use, cheap, and using reliable, but its function is still more single, can not accomplish in real time
Monitoring, such as when the pressure of tire is abnormal, it is necessary to which inflated for deflated regulation is repeated, regulation every time needs again afterwards
Measurement, until regulation is in place.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, a kind of cost of the utility model offer is cheap and service-strong has
The tire pressure gauge of decompression function.
The technical scheme in the invention for solving the technical problem is：A kind of tire pressure gauge with decompression function, bag
Joint is included, one end of the joint is provided with pressure gauge, and the other end of the joint is provided with measurement head, opened up in described measurement head
There is stomata, be provided with inlet channel in described joint, described stomata connects with described inlet channel；
The side wall of the joint is provided with relief valve, and described relief valve includes valve body, offers and let out in described valve body
Pressure passageway, described pressure release passage is interior to be provided with pressure release bar, and one end of the pressure release bar is provided with plug, and described plug stretches into described
Inlet channel in, be provided with sealing ring between described plug and described valve body, the other end of the pressure release bar, which is provided with, to be pressed
Button, the first spring is arranged with described pressure release bar, one end of first spring abuts with the valve body, first spring
The other end abutted with described button.
Further, regulating valve is provided with described inlet channel, the regulating valve is provided with second close to one end of pressure gauge
Spring, is additionally provided with the first sealing gasket between described second spring and described regulating valve, described regulating valve can be with air inlet
The forward and backward movement of change of channel inner pressure.
Further, described regulating valve and the inwall of the joint are directly provided with sealing ring.
Further, described second spring is pagoda spring.
Further, the second sealing gasket is provided with described measurement head, bedding core is provided with the second described sealing gasket, it is described
Stomata is arranged on described bedding core, and the guide pin bushing being adapted with valve cock on tire is additionally provided with described measurement head.
The beneficial effects of the utility model are：Decompression function is realized by the relief valve for being arranged on joint side, reached
Pressure release and the in real time function of monitoring tire pressure, it is simple to operate, the time of tire pressure regulation is greatlyd save, and cost is cheap.
