The tire pressure sensor includes a quick-connect base and a sensor housing, with the sensor housing located at the other end of the quick-connect base. The other end of the first valve body is connected to the quick-connect base on its outer side. A spring is installed on the inner side of the quick-connect base, and a screw post is threaded onto the other end of the quick-connect base. A sliding groove is formed at the bottom inner side of the quick-connect base, allowing for sliding between the groove and the first valve body. A limiting groove is formed in the middle inner side of the quick-connect base. One end of the second valve body is connected to the quick-connect base.

[0008] Preferably, a valve core is disposed on the inner side of the first air nozzle body, and the valve core is threadedly connected to the first air nozzle body.

[0009] Preferably, the screw post is a headless screw structure.

[0010] Preferably, a dust cap is connected to one end of the first air nozzle body.

[0011] Preferably, the limiting groove is a blind groove structure.

[0012] Preferably, the first air nozzle body forms an elastic structure with a spring and a quick-connect seat.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up a sealing gasket, a first air nozzle body, a quick-connect seat, etc., a spring is manually placed in the quick-connect seat, and then a screw post is connected to it. Then, the first air nozzle body made of aluminum or the second air nozzle body made of copper rod and rubber is connected to it. Its end is inserted along the sliding groove, the spring is squeezed and rotated 90°. Under the elastic action of the spring, the end of the air nozzle body is locked into the limiting groove, completing the splicing work of the air nozzle body and the sensor.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 The tire pressure sensor quick-connect structure includes a first valve body 1, a second valve body 12, and a tire pressure sensor. A clamping cap 6 is fitted onto one side of the outer wall of the first valve body 1, and a sealing gasket 5 abuts against one side of the clamping cap 6. A valve core 4 is disposed on the inner side of the first valve body 1, and the valve core 4 is threadedly connected to the first valve body 1. A dust cap 7 is connected to one end of the first valve body 1, and a sealing ring is provided between the dust cap 7 and the clamping cap 6 for sealing. The tire pressure sensor includes a quick-connect base 8 and a sensor housing 2, and the other end of the quick-connect base 8 is injection-molded with the sensor housing 2. The other side of the air nozzle body 1 is connected to the quick-connect seat 8. A spring 9 is installed on the inner side of the quick-connect seat 8. A screw post 3 is threaded to the other end of the quick-connect seat 8. The screw post 3 is a headless screw structure. The screw post 3 serves as the support point of the spring 9 and is threaded to the quick-connect seat 8, so that the placement point of the spring 9 is fixed and will not be excessive. The first air nozzle body 1 forms an elastic structure with the quick-connect seat 8 through the spring 9. Through the push of the spring 9, it can abut and press the first air nozzle body 1 that slides into the limiting groove 11, and it is not easy to fall out of the limiting groove 11.

[0024] The quick-connecting seat 8 has a sliding groove 10 at its inner bottom end. The sliding groove 10 is slidably connected to the first air nozzle body 1. The sliding groove 10 is designed to facilitate the first air nozzle body 1 to slide along the sliding groove 10 and smoothly enter the limiting groove 11. The quick-connecting seat 8 has a limiting groove 11 in the middle of its inner side. The limiting groove 11 is a blind groove structure. The limiting groove 11 is designed to facilitate the limiting of the end of the first air nozzle body 1. One end of the second air nozzle body 12 is connected to the quick-connecting seat 8.

[0025] Example 1: The worker places the spring 9 into the quick connector 8, connects the screw post 3 to it, and then inserts the end of the first air nozzle body 1, which is made of aluminum, along the slide groove 10. The spring 9 is squeezed and rotated 90°. Under the elastic action of the spring 9, the end of the first air nozzle body 1 is engaged in the limiting groove 11, thus completing the splicing of the first air nozzle body 1 and the sensor.

[0026] Example 2: The worker places the spring 9 into the quick connector 8, connects the screw post 3 to it, and then inserts the end of the second air nozzle body 12, which is composed of a copper rod and a rubber nozzle, along the slide groove 10. The worker squeezes the spring 9 and rotates it 90°. Under the elastic action of the spring 9, the end of the second air nozzle body 12 is engaged in the limiting groove 11, thus completing the splicing of the second air nozzle body 12 and the sensor.

[0027] Working principle: In use, the operator first places the spring 9 into the quick-connect seat 8, then connects the screw post 3 to it, and then inserts the end of the air nozzle body along the slide groove 10, compresses the spring 9, and rotates it 90°. Under the elastic action of the spring 9, the end of the air nozzle body is locked into the limiting groove 11, completing the splicing of the air nozzle body and the sensor. (It should be noted that the specific model and specifications of the electrical parts involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.)

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
