Description

Technical Field

[0001] This utility model relates to a tire pressure detection device for vehicle inspection. Background Art

[0002] Vehicle inspection requires checking the tire pressure of all four tires. The current method involves using a tire pressure gun. If the tire pressure is insufficient, the trigger is pulled to inflate the tires; if the pressure is excessive, the bleed screws are opened to release the air. The current tire pressure gun requires a hose connected to the air compressor. Therefore, when checking the tire pressure of all four tires, the hose must be wrapped around the vehicle at least half a turn. After the tire pressure check is completed, the hose must be immediately rolled up, otherwise it is very easy for the vehicle to run over or snag it, making the operation quite cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a tire pressure testing device for vehicle inspection, which solves the problem that existing tire pressure testing requires the use of long hoses, making tire pressure testing inconvenient.

[0004] To solve the above problems, the technical solution of this utility model is as follows:

[0005] A tire pressure testing device for vehicle inspection includes a tire pressure gun, which includes a gun body, an air hose, a bleed screw, a trigger, and a tire pressure gauge. The air inlet of the tire pressure gun is connected to one end of a hose via a first quick connector, and the other end of the hose is connected to one end of a pressure regulating valve. The other end of the pressure regulating valve is connected to a compressed air cylinder via a connecting pipe.

[0006] The pipe is connected to a second quick connector and a safety valve.

[0007] A pressure gauge is installed on the compressed air cylinder.

[0008] The beneficial effects of this utility model are as follows: It replaces the air compressor with a compressed air bottle, allowing the compressed air bottle to move with the tire pressure gun to measure the pressure, eliminating the need for the hose to contact the vehicle and completely solving the problem of vehicle pressure hose or hose attachment. At the same time, this device has the functions of pressure measurement, deflation and inflation, greatly improving the convenience of vehicle tire pressure monitoring. Furthermore, the device has a simple structure and is easy to manufacture. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings:

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] like Figure 1 As shown, a tire pressure testing device for vehicle inspection includes a tire pressure gun. The tire pressure gun includes a gun body 14, an air hose 12, a bleed screw 13, a trigger 10, and a tire pressure gauge 11. The air inlet of the tire pressure gun is connected to one end of a flexible hose 5 via a first quick connector 9. The other end of the flexible hose 5 is connected to one end of a pressure regulating valve 4. The other end of the pressure regulating valve 4 is connected to a compressed air cylinder 1 via a connecting pipe 8. The pressure is adjusted to 2.3 bar by the pressure regulating valve 4. The pressure of the compressed air cylinder 1 is 8-9 bar, and its volume is 2 L.

[0014] When using this utility model: After connecting the air hose 12 to the vehicle tire, the tire pressure gauge 11 displays the tire pressure of the vehicle tire. If the tire pressure is too high, the air is released through the bleed screw 13. If the tire pressure is insufficient, the trigger 10 is pulled to replenish the tire pressure of the vehicle tire through the compressed air bottle 1.

[0015] This replaces the air compressor with compressed air cylinder 1, allowing compressed air cylinder 1 to move with the tire pressure gun to measure pressure, and also has the functions of pressure measurement, deflation and inflation, making operation simple and convenient.

[0016] The connecting pipe 8 is connected to a second quick connector 3 and a safety valve 7. The second quick connector 3 facilitates the inflation of the compressed air cylinder 1, while the safety valve 7 is used to limit the pressure of the compressed air cylinder 1 to prevent over-inflation.

[0017] A pressure gauge 6 is installed on the compressed air cylinder 1. The pressure gauge 6 allows for easy observation of the air pressure in the compressed air cylinder 1.

[0018] A U-shaped handle 2 is fixedly connected to the compressed air cylinder 1, with the end of the U-shaped handle 2 away from the compressed air cylinder 1 tilted upwards. The handle 2 serves two purposes: firstly, it allows the operator to easily carry the compressed air cylinder 1; secondly, it facilitates winding the hose 5 and placing the tire pressure gun.

[0019] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
