Description

Technical Field

[0001] This utility model relates to the field of detection connector technology, specifically an air conditioning refrigerant temperature detection connector. Background Technology

[0002] The patent announcement number CN220136601U discloses an airtightness testing device for air conditioning refrigerant pipe joints, which includes a testing mechanism that is detachably and sealed on the pipe joint. The testing mechanism has an axial hole, and a flared tube is installed in the axial hole. One end of the flared tube is provided with a flared mouth. The pipe joint has a sealing surface. The testing mechanism fixes and presses the flared mouth onto the sealing surface of the pipe joint by threads to make the inner cavity of the pipe and the flared tube in a sealed communication. The other end of the flared tube is detachably and sealed to a pressure gauge. An annular cavity for containing liquid is formed between the inner wall of the axial hole and the outer wall of the flared tube.

[0003] By setting up a sealed horn tube that matches the existing air conditioning refrigerant high-pressure pipe joint, it can simultaneously determine whether there is a leak in the high-pressure pipe joint by observing the changes in the pressure gauge reading. It can also further determine whether a leak has occurred and the location of the leak by observing whether the liquid in the annular space is bubbling or overflowing.

[0004] However, when testing the refrigerant temperature of the air conditioner, the installation of the testing connector is inconvenient, and the connection between the testing connector and the air conditioner refrigerant temperature is not well sealed, resulting in poor accuracy of this solution for testing the air conditioner refrigerant temperature. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air conditioning refrigerant temperature detection connector, which solves the problems of inconvenient installation of the connector and poor sealing at the connection between the connector and the air conditioning refrigerant temperature sensor when detecting the refrigerant temperature.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning refrigerant temperature detection connector, comprising a detection connector, a limit ring being threadedly connected to the surface of the detection connector, a sealing ring being fixedly installed at one end of the limit ring, a guide tube being fixedly installed at the other end of the detection connector, a detector being fixedly installed at one end of the guide tube, and a limit component being fixedly installed at one end of the detection connector;

[0007] The limiting component includes a positioning block fixedly installed at one end of the detection connector. Telescopic rods are fixedly installed on both sides of the surface of the positioning block. Springs are sleeved on the surface of the telescopic rods. A limiting block is fixedly installed at one end of the telescopic rods.

[0008] In one specific embodiment, a resisting block is fixedly installed at one end of the telescopic rod, the diameter of the resisting block being larger than the diameter of the spring, and the back of the resisting block is fixedly installed at one end of the spring.

[0009] In one specific embodiment, the surface of the limiting block is provided with an embedding groove, and a limiting pad for improving stability is embedded inside the embedding groove.

[0010] In one specific embodiment, the diameter of the sealing ring is larger than the diameter of the detection connector, and the sealing ring seals the gaps in the detection connector.

[0011] In one specific embodiment, the surface of the detector is provided with an observation groove, and the interior of the observation groove is provided with observation glass.

[0012] In one specific embodiment, the detector has an internal rotating pointer, one end of which has a scale for observation.

[0013] Compared with the prior art, this utility model provides an air conditioning refrigerant temperature detection connector, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, by using a detection connector, a limiting ring, a sealing ring, a guide tube, a detector, and a limiting component, during use, the operator threaded the detection connector onto the surface of the air conditioning duct. Then, the operator rotates the limiting ring through the detection connector. When the limiting ring rotates, the sealing ring at one end seals one end of the detection connector. The detector at one end of the guide tube detects the gas temperature inside the air conditioning duct. The limiting component facilitates the operator's positioning of the detection connector, thus improving the efficiency of installing the detection connector.

[0015] With the limiting component set by this utility model, during use, the personnel insert the detection connector into the air conditioning pipe, and then the air conditioning pipe will squeeze the limiting block. After the limiting block is squeezed, it will squeeze the spring on the surface of the telescopic rod. After the spring is squeezed, it will move the limiting block to both sides synchronously through the positioning block rod. When the limiting block moves, the detection connector will be installed and positioned, which improves the efficiency of installing the detection connector. Attached Figure Description

[0024] The specific problem addressed in this embodiment is the inconvenience of installing the detection connector 1 and the poor sealing at the connection between the detection connector 1 and the air conditioning refrigerant temperature sensor when detecting the refrigerant temperature. This invention utilizes the configuration of the detection connector 1, limiting ring 2, sealing ring 3, guide tube 4, detector 5, and limiting component 6. During use, the operator threaded the detection connector 1 onto the surface of the air conditioning duct. Then, the operator rotates the limiting ring 2 through the detection connector 1. As the limiting ring 2 rotates, the sealing ring 3 at one end seals one end of the detection connector 1. The detector 5 at one end of the guide tube 4 detects the gas temperature inside the air conditioning duct. The limiting component 6 facilitates the positioning of the detection connector 1, improving the efficiency of its installation.

[0025] The limiting component 6 includes a positioning block 61 fixedly installed at one end of the detection connector 1. Telescopic rods 62 are fixedly installed on both sides of the surface of the positioning block 61. A spring 63 is sleeved on the surface of the telescopic rod 62. A limiting block 64 is fixedly installed at one end of the telescopic rod 62, and a resisting block is fixedly installed at the other end of the telescopic rod 62. The diameter of the resisting block is larger than the diameter of the spring 63. The back of the resisting block is fixedly installed at one end of the spring 63. An embedding groove is formed on the surface of the limiting block 64, and a limiting pad for improved stability is embedded inside the embedding groove. In this specific embodiment, during use, the personnel insert the detection connector 1 into the air conditioning duct. Subsequently, the air conditioning duct will squeeze the limiting block 64. After the limiting block 64 is squeezed, it will squeeze the spring 63 on the surface of the telescopic rod 62. After the spring 63 is squeezed, the limiting block 64 will move synchronously to both sides through the positioning block rod 1. When the limiting block 64 moves, the detection connector 1 will be installed and positioned, improving the efficiency of installing the detection connector 1.

[0026] In this specific embodiment, the diameter of the sealing ring 3 is larger than the diameter of the detection connector 1. The sealing ring 3 seals the gap of the detection connector 1. An observation groove is provided on the surface of the detector 5. An observation glass is provided inside the observation groove. A pointer is rotatably provided inside the detector 5. One end of the pointer is provided with a scale for observation.
