Description

A kind of tire gauge detecting device

Technical field

The utility model belongs to the detection field of the instrument measuring hydrodynamic pressure.

Background technology

The general vehicle at road driving is after Long-Time Service, body part part there will be consume and need maintain repairing, wherein namely tire maintenance is a wherein ring of vehicle maintenance, it is utilize an inflating gun that the tire pressure of current tire maintenance detects, this inflating gun is established a switch, one tire pressure takes into account two openings, wherein one end open is via tubes connection cranked tire valve, other end opening is via tubes connection one air compressor, air compressor compressed air is sent to inflating gun, opening inflating gun switch makes pressurized air be sent in tire, current tire pressure value in tire can be observed by tire gauge while inflating, but the numerical value of this tire gauge measured by under Long-Time Service may have deviation, if do not correct and use in good time, though possible tire gauge display numerical value is normal, but in fact tire internal gas pressure and tire gauge measured value difference to some extent, action when utilizing the vehicle of this tire will travel because tire pressure is not enough, reaction becomes slow, vehicle becomes manipulation not easily, the situation that fuel oil use amount increases occurs, if tire pressure is greater than normal value, the dangerous situation probably can blown out when then travelling.

Utility model content

In order to check whether tire gauge measured value is normal, avoid the various problems that tire pressure is not enough or tire pressure is excessive produced whereby, the utility model provides a kind of tire gauge detecting device, and this tire gauge detecting device is not only scientific and reasonable for structure, and test accurately.

The utility model solves the technical scheme that its technical matters adopts: a kind of tire gauge detecting device, comprise one point of bearing, a test section, a linking part, a valve and a guide hole, its structure is: one point of bearing runs through an air flue, this air flue connects a valve and a linking part, is separately provided with the air flue that at least one test section is connected to point bearing; This test section is taken into account a connecting pipe by a pressure and is formed, and one end of this connecting pipe is connected on air flue, and the other end then establishes a rapid-acting coupling Bonding pressure meter; This linking part is a retaining valve, a pressure regulator valve and a guide hole sequentially connect to form, and can establish a support portion at a point rest base.

The beneficial effects of the utility model are that the pressurized air making to produce in air compressor is filled with into point bearing via conduit from inflating gun or guide hole direction, and pressurized air pours into in test section by the hole being connected air flue by end face, both measured values manometric of the pressure gauge of test section and inflating gun are compared, because this pressure is in respect of two, have double acknowledge function, test accurately.

Embodiment

Embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a kind of tire gauge detecting device, comprise: one point of bearing 10, this point of bearing 10 shape is strip, and provide a hole separately in two ends, left and right, run through an air flue between two holes, the relative position in the end face two ends of point bearing 10 runs through the hole that is communicated to air flue separately, and the hole inner edge of point bearing appearance is provided with a screw thread; One test section 20, comprises pressure gauge 21 and a connecting pipe 22, and run through a hole in the middle of this connecting pipe 22, wherein the outer rim of one end is provided with a screw thread, and the other end is provided with a rapid-acting coupling 23, utilizes rapid-acting coupling 23 pressure gauge 21 can be engaged fast or remove; One linking part 30, comprise retaining valve 31, pressure regulator valve 32 and a guide hole 33 sequentially connects to form, wherein this retaining valve 31 can limit gas unidirectional circulation, and pressure regulator valve 32 has adjusting gas flow magnitude function, and the other end connecting pressure regulator valve 32 at retaining valve 31 is provided with a screw thread; One valve 40, just can conducting when this valve 40 must have a tubes connection, and the other end outer rim that valve 40 is connected with guide hole is provided with a screw thread; One support portion 50, can fix point bearing 10; First combine bottom support portion 50 and point bearing 10 when this tire gauge detecting device 1 combines, the hole at point bearing about 10 two ends is spirally connected valve 40 and linking part 30 separately, and the end face two ends of point bearing 10 are spirally connected separately, the connecting pipe 22 of test section 20, so forms a tire gauge detecting device 1.

When this tire gauge detecting device 1 uses, retaining valve 31 due to this linking part 30 can only make gas unidirectional circulate, therefore an inflating gun A to be detected cannot be connected on the guide hole 33 of linking part 30, and can only be connected on the valve 40 of point bearing 10, and provide a compressed-air actuated air compressor B to have two kinds of connected modes, one is be connected to inflating gun A, and two is be connected on the guide hole 33 of linking part 30; This inflating gun A is a lever A1, and a tire gauge A2 is established in its front, and the back side is provided with a switch A3, and this lever rear end is provided with a connector A4.

If air compressor B is connected to inflating gun A, just as shown in Fig. 1, Fig. 2, the first pipeline T1 that this air compressor B extends is connected to the connector A4 of inflating gun A, and the second pipeline T2 that inflating gun A extends from another connector A4 is again connected to valve 40; By this mounting means, air compressor B compressed air is first sent to inflating gun A, now user open inflating gun A switch A3 by gas communication to tire gauge detecting device 1, the air pressure that two of test section 20 pressure gauge 21 and the tire gauge A2 three of inflating gun A detect can be compared, judge whether the tire gauge A2 of inflating gun A is normal thus.
