Abstract
The utility model relates to a portable tyre pressure tester which is formed in a mode that a piston is embedded on the upper part of a cylinder body, a spring is arranged in the piston, the lower part of the cylinder body is connected with a thimble by screws, and an outer ring of the thimble is provided with a sealing ring. The utility model is characterized in that the middle of the thimble is provided with an air inlet, a plurality of sealing rings are arranged between the cylinder body and the piston, and the upper part of the cylinder body is connected with an upper cover by the screws. A shell of the cylinder body is provided with color strips. The size change of the internal gas pressure of a tyre does up-and-down movement by the elasticity of the piston in the cylinder body, which causes the up-and-down movement of the piston. The size of the spring can be changed according to different sizes of the internal gas pressure of each tyre. The shell of the cylinder is inlaid with colorful graduation strips, and the change of a specific tyre pressure value can be known directly, which is convenient for a driver to know the change of the tyre clearly and directly. The potential air leaking phenomenon and flat tyre phenomenon can be prevented according to the change of the tyre pressure of the tyre. A suitable tyre pressure value can be kept, and the utility model plays an important role in the security assurance of a whole vehicle. The utility model has the advantages of simple structure, small volume and convenient carryover.
Description
Technical field
The utility model relates to a kind of detected pressures indicator, especially a kind of portable tire voltage detector that is used for automobile.
Background technology
Along with the development of 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, and the major traffic accidents that take place on the domestic highway have 70% to be because tyre break causes approximately.Prior art mainly adopts range estimation and hand-held gas-pressure survey meter to detect, the latter needs regularly special in the detection of tyre service station, not only time-consuming, bothersome, and uneconomical, inconvenient, and have the vehicle of tire pressure automatic detection device, and the manufacturing cost height of this device, volume is big, and can not show at any time that concrete force value brought difficulty to driver safety, be difficult to guarantee the safety traffic of vehicle.
Summary of the invention
It is a kind of simple to operate, easy to carry that the utility model provides, and volume is little, compact conformation, a kind of portable tire voltage detector of display of tyre force value intuitively.
For finishing above-mentioned purpose, technical solution adopted in the utility model, a kind of portable tire voltage detector comprises the built-in piston in cylinder body top, and spring is set in the piston, inferior part of the cylinder block is by the thimble that is threaded, the thimble outer ring is equipped with O-ring seal, is characterized in, air admission hole is set in the middle of the thimble, be equipped with multiple-sealed circle between cylinder body and the piston, the cylinder body upper end is by the loam cake that is threaded.The cylinder body shell is provided with color bar.Loam cake is hexagon socket head cap screw or a word screw or a Philip's head screw.
The beneficial effects of the utility model are: tire is the automobile lifeline, and the air pressure in the tire will directly influence the safety traffic of automobile.Thereby the spring force of tire internal gas pressure size variation by the cylinder body inner carrier moves up and down piston moved up and down, and according to the sizes values difference of every kind of tire internal gas pressure, can change the size of spring.Be embedded with the color scale bar in the shell of cylinder, can recognize intuitively that concrete tire pressure value changes.Be convenient to the driver intuitively, clearly see tire clearly and change.At any time the tire pressure changed condition of tire, thus potential gas leakage, flat tire phenomenon prevented, keep suitable tire pressure value, guarantee that the security of car load plays crucial effects, the utility model is simple in structure, volume is little, be easy to carry.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1, a kind of portable tire voltage detector, comprise the built-in piston 5 in cylinder body 3 tops, spring 2 is set in the piston 5, and cylinder body 3 bottoms connect thimble 6 by screw thread 8, and the thimble outer ring is equipped with O-ring seal 7, be characterized in, in the middle of the thimble 6 air admission hole 10 is set, is equipped with multiple-sealed circle 9 between cylinder body 3 and the piston 5, cylinder body 3 upper ends connect loam cake 1 by screw thread 8.
Tire is the automobile lifeline, and the air pressure in the tire will directly influence the safety traffic of automobile.Thereby the spring force of tire internal gas pressure size variation by the cylinder body inner carrier moves up and down piston moved up and down, and according to the sizes values difference of every kind of tire internal gas pressure, can change the size of spring.Be embedded with the color scale bar in the shell of cylinder, can recognize intuitively that concrete tire pressure value changes.Be convenient to the driver intuitively, clearly see tire clearly and change.At any time the tire pressure changed condition of tire, thus potential gas leakage, flat tire phenomenon prevented, keep suitable tire pressure value, guarantee that the security of car load plays crucial effects, the utility model is simple in structure, volume is little, be easy to carry.
