[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A laboratory quick-connect temperature and pressure connector, such as Figures 1-2 As shown, it includes a connector body 1, and a head interface 2 is provided at the tail of the connector body 1. The head interface 2 is connected to the high and low pressure charging ports of the car air conditioning system. The car air conditioning pipe charging ports used by the head interface 2 have only two standard sizes, namely the high pressure charging port and the low pressure charging port. The connector is universal in all relevant experimental processes.

[0021] A pressure port 3 is provided on the side wall of the connector body 1. A pressure sensor is provided on the pressure port 3 and connected thereto. A pressure measuring tube connector 4 is provided on the pressure sensor and detachably connected to the pressure port 3. A sealing gasket 10 is fixedly connected to the opening of both the pressure measuring tube connector 4 and the pressure port 3.

[0022] A hollow cylindrical sealing clip 5 is fixedly connected to the inner wall of the pressure port 3. The diameter of the pressure measuring pipe connector 4 is smaller than the inner ring diameter of the sealing clip 5. A material guiding slope 9 is provided on the lower end face of the sealing clip 5.

[0023] The pressure interface 3 is provided with a limiting device for limiting the pressure measuring pipe connector 4. The limiting device includes a plurality of contact rods 6 arranged in a ring array. The plurality of contact rods 6 are fixedly connected to the inner wall of the pressure interface 3. An elastic plate 7 is fixedly connected to the opening of the pressure measuring pipe connector 4. The elastic plate 7 is hollow cylindrical and has a notch 8 at the opening.

[0024] The abutment rod 6 is arc-shaped. When the pressure measuring tube connector 4 is inserted into the pressure port 3, the abutment rod 6 will be inserted into the hollow part formed by the elastic sheet 7.

[0025] Working principle: When the pressure sensor needs to be installed together with the connector body 1, the pressure testing tube connector 4 is inserted into the pressure interface 3, so that it is inserted between the sealing clips 5. The sealing clips 5 are made of highly elastic rubber and their diameter is smaller than that of the pressure testing tube connector 4. Therefore, after the pressure testing tube connector 4 is inserted into the sealing clips 5, the sealing clips 5 will deform due to compression, and the elastic deformation force will clamp the pressure testing tube connector 4. The guide slope 9 below the sealing clips 5 can form a flare to facilitate the insertion of the pressure testing tube connector 4. When the pressure testing tube connector 4 is inserted until the abutment rod 6 extends into the pressure testing tube connector 4, the elastic plate 7... The pressure sensor will flip outward due to the pressure of the contact rod 6, forming an upward trumpet shape, which will be stuck between the contact rod 6 and the sealing clip 5, further limiting the pressure measuring tube connector 4 and enhancing the sealing during the testing process. The notch 8 allows the elastic plate 7 to flip outward and open, realizing the installation of the pressure sensor. When the pressure sensor needs to be disassembled after the test is completed, hold the pressure measuring tube connector 4 and pull it outward with force. The sealing clip 5 will drive the elastic plate 7 to flip back to the vertical position. Pull the pressure measuring tube connector 4 out with force to separate the two. Disassembly and assembly can be achieved by plugging and unplugging, making the operation more convenient.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
