Abstract
The utility model relates to a detecting pressure indicator, in particular to a tyre pressure detector used for the valve core of the automobile, comprising a cylinder body which is connected with an air inlet hole thimble through the screw. A sealing ring is provided between the thimble and the cylinder body. The utility model is characterized in that: a plunger with a spring is provided in a cylinder which is integrally formed with the cylinder body; a sealing ring is provided between the cylinder and the plunger. A transparent magnifier with the graduation is inserted in the middle of the outer shell of the cylinder. The chromatic marking lines are provided on the edge of the top of the plunger. The concrete tyre pressure value can be visually known through observing the transparent magnifier with the graduation which is inserted in the middle of the outer shell of the cylinder. Additionally, the tyre pressure values can be roughly known through observing the chromatic marking lines provided on the edge of the top of the plunger. The change of the size of the tyre pressure can be conveniently, visually and clearly observed by the driver.
Description
Technical field
The utility model relates to a kind of detected pressures indicating device, especially a kind of tire voltage detector that is used for the automobile valve inside.
Background technology
Development along with communications, at present the speed of a motor vehicle of travelling on than ground in the speed of a motor vehicle of running on expressway is fast several times, keep suitable tire pressure value, the safety of guaranteeing car load plays crucial effects, prior art mainly adopts range estimation and hand-held gas-pressure survey meter to detect, the former is rule of thumb often inaccurate, is difficult to guarantee the safety traffic of vehicle, and the latter needs regularly special in the detection of tyre service station, not only time-consuming, bothersome, and uneconomical convenience, and have the vehicle of tire pressure automatic checkout equipment, the manufacturing cost height of this device, volume is big, and can not show concrete force value at any time, has brought difficulty to driver's operation.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, a kind of tire voltage detector of display of tyre force value and pressure variation intuitively.
For finishing above-mentioned purpose, technical solution adopted in the utility model is, a kind of tire voltage detector, comprise that cylinder body has the induction opening thimble by being threaded, between thimble and cylinder body seal ring is set, be characterized in that the cylinder integrally formed with cylinder body is built-in with the piston that has spring, is equipped with seal ring between cylinder and piston.
Be embedded with the transparent eye gauge that has scale, piston head sideband the colorful one groove in the middle of the shell of cylinder.
The beneficial effects of the utility model are, piston is by the elastic force effect of spring, according to tire internal gas pressure size variation piston is moved up and down, be embedded with the transparent scale mark eye gauge that has in the middle of adopting the shell of observing cylinder, can recognize concrete tire pressure value intuitively, in addition, by observing piston head sideband the colorful one groove, can understand the tire pressure value roughly and change.Can replace the valve cap on the tire valve, be used for the variation of continuous uninterrupted indicator wheel air pressure, be convenient to chaufeur intuitively, the clear size of seeing the pressure variation in the tire clearly.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1, a kind of tire voltage detector comprises that cylinder body 1 has the thimble 3 of induction opening 4 by being threaded, between thimble 3 and the cylinder body 1 seal ring 5 is set, its characteristics, the cylinder 2 integrally formed with cylinder body 1 is built-in with the piston 6 that has spring 7, and 6 in cylinder 2 and piston are equipped with seal ring 5.
Be embedded with the transparent eye gauge that has scale 9 in the middle of the shell 8 of cylinder 2, piston 6 top sides have the groove 10 of color.
In use, cylinder body 1 is fixed on the tire valve, thimble 3 unseat the valve mouth plunger tips, gas in the tire moves up and down having spring 7 pistons in the cylinder 2 by the induction opening 4 of thimble 3, as shown in Figure 1, air pressure after the inflation moves to cylinder 2 opaque sections with the initial pressure that piston 6 overcomes spring 7, at this moment, display automobile tire internal gas pressure abundance, piston 6 inner springs 7 discharge elasticity when tire pressure reduces, and promote piston 6 readjustments, make piston 6 be positioned at cylinder 2 transparent positions, therefore, the centre of the shell 8 by observing cylinder 2 is embedded with the transparent scale eye gauge that has, and can recognize concrete tire pressure value intuitively, in addition, by observing piston head sideband the colorful one groove, can understand the tire pressure value roughly and change.Can replace the valve cap on the tire valve, be used for the variation of continuous uninterrupted indicator wheel air pressure.
