[0002] Automobile air-conditioning pipeline connectors are widely used in various parts of the automobile air-conditioning system, used to connect the air-conditioning compressor with other system components, such as condensers, evaporators, etc., to ensure the smooth circulation of the refrigerant in the system. In addition, they can also be used to connect the joints of different pipelines to achieve the overall connection of the air-conditioning system.
[0003] During the long-term operation of the automobile air-conditioning system, factors such as temperature changes and vibrations may cause the mating gap between the connector and the pipeline to increase, and then the connection may become loose. A loose connection may cause air leakage at the connection between the pipeline and the seal, and then cause refrigerant leakage. Refrigerant leakage will not only affect the refrigeration effect of the air-conditioning system, but also reduce the refrigeration performance of the air-conditioning. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an automobile air-conditioning pipeline connector to solve the problems raised in the above background art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] An automobile air-conditioning pipeline connector, comprising:
[0007] A connecting pipe, on the inner wall of which there is a first threaded port, on the outer wall of which there is a second threaded port, on which there is a fastening mechanism, and on which there is a sealing mechanism interlocked with the fastening mechanism;
[0008] The fastening mechanism is used to enhance the connection stability between the air-conditioning pipeline and the connecting pipe;
[0009] The sealing mechanism increases the sealing performance of the plugging component inside the connecting pipe against the pipeline when the fastening mechanism fastens between the air-conditioning pipeline and the connector.
[0010] Preferably, the first threaded port is threadedly connected to the air-conditioning pipeline, and the plugging component is located on the inner wall of the connecting pipe.
[0011] Preferably, the fastening mechanism includes a first sleeve, on the inner wall of which there is a third threaded port, and the third threaded port is threadedly connected to the second threaded port.
[0012] Preferably, the fastening mechanism further includes extrusion blocks, which are equidistantly arranged at the pipe orifice of the connecting pipe, and the side of the extrusion block away from the inner wall of the connecting pipe is an inclined curved surface.
[0013] Preferably, a cushion block is arranged on one side of the extrusion block close to the inner wall of the connecting pipe, and the cushion block is made of a material with a large friction coefficient such as rubber or silica gel.
[0014] Preferably, after the extrusion block is fixedly connected to the cushion block, the inner wall diameter thereof is adapted to the inner wall diameter of the connecting pipe.
[0015] Preferably, the sealing mechanism includes a second sleeve, the second sleeve is arranged on the side of the first sleeve away from the extrusion block, and the inner wall thereof slides on the outer surface of the connecting pipe.
[0016] Preferably, the second sleeve is fixedly connected to the pipe orifice on the side of the first sleeve away from the extrusion block, an opening is formed through one end of the second sleeve away from the first sleeve, and an extrusion ring is arranged in the opening.
[0017] Preferably, the plugging assembly includes a push pipe, and the push pipe is slidably connected to the inner wall of the connecting pipe.
[0018] Preferably, a sealing gasket is arranged on the side of the push pipe away from the opening, the size of the sealing gasket is adapted to the size of the push pipe and is clamped with the push pipe.
[0019] Compared with the prior art, the utility model has the following beneficial effects:
[0020] By rotating the first sleeve of the fastening mechanism to squeeze the extrusion block, the cushion block is urged to closely fit the air-conditioning pipeline, increasing the friction between the pipeline and the connector, so as to ensure that the connection between the pipeline and the air-conditioning connector is more stable. By firmly connecting the pipeline and the air-conditioning connector, the failure risk caused by insecure connection can be reduced. This helps to reduce the system downtime and improve the reliability and availability of the system.
[0021] When the first sleeve in the fastening mechanism moves linearly, it drives the second sleeve of the sealing mechanism, so that the extrusion ring at the opening of the second sleeve squeezes the push pipe. Furthermore, the sealing gasket arranged at the end of the push pipe gradually closely fits the pipe orifice of the air-conditioning pipeline. When the sealing gasket is further squeezed and fits the air-conditioning pipeline, the sealing performance will be significantly improved. This can effectively prevent the leakage of refrigerant, air or other fluids from the pipeline, ensuring the normal operation of the air-conditioning system. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Among them, when the fastening mechanism fastens the air-conditioning pipeline and the connector, the sealing mechanism increases the sealing performance of the pipeline by the plugging component inside the connecting pipe 1. The first threaded port 102 is threadedly connected with the air-conditioning pipeline, and the plugging component is located on the inner wall of the connecting pipe 1.
[0036] Furthermore, the fastening mechanism includes a first sleeve 2. The inner wall of the first sleeve 2 is provided with a third threaded port 201, and the third threaded port 201 is threadedly connected with the second threaded port 103. The fastening mechanism also includes an extrusion block 203, which is equidistantly arranged at the pipe orifice of the connecting pipe 1. The side of the extrusion block 203 away from the inner wall of the connecting pipe 1 is an inclined curved surface. A cushion block 204 is arranged on the side of the extrusion block 203 close to the inner wall of the connecting pipe 1.

After the extrusion block 203 and the cushion block 204 are fixedly connected, the inner diameter of the inner wall is adapted to the inner diameter of the connecting pipe 1.
[0037] Through the above embodiments, the effects achieved by the utility model are as follows: By rotating the first sleeve 2, the inner wall of the first sleeve 2 applies an extrusion force to the outer surface of the inclined extrusion block 203, thereby promoting the cushion block 204 to fit the air-conditioning pipeline and then fastening the pipeline, which can ensure a more stable connection between the pipeline and the air-conditioning connector. This stability can prevent the pipeline from loosening or shifting due to vibration or temperature changes during operation. Embodiment
[0038] Please refer to Figures 2 - 5 , an automotive air-conditioning pipeline connector, comprising:
[0039] Connecting pipe 1, the inner wall of the connecting pipe 1 is provided with a first threaded port 102, the outer wall of the connecting pipe 1 is provided with a second threaded port 103, a fastening mechanism is arranged on the connecting pipe 1, and a sealing mechanism interlocked with the fastening mechanism is arranged on the connecting pipe 1; the sealing mechanism increases the sealing performance of the pipeline by the plugging component inside the connecting pipe 1 when the fastening mechanism fastens the air-conditioning pipeline and the connector.
[0040] Among them, the sealing mechanism includes a second sleeve 3. The second sleeve 3 is arranged on the side of the first sleeve 2 away from the extrusion block 203, and the inner wall slides on the outer surface of the connecting pipe 1. The second sleeve 3 is fixedly connected to the pipe orifice on the side of the first sleeve 2 away from the extrusion block 203. An opening 301 is formed through the end of the second sleeve 3 away from the first sleeve 2, and an extrusion ring 302 is arranged in the opening 301.
[0041] Further, the plugging component includes a push tube 303 which is slidably connected to the inner wall of the connecting tube 1. A sealing gasket 304 is arranged on the side of the push tube 303 away from the opening 301. The size of the sealing gasket 304 is adapted to the size of the push tube 303 and is snap-connected to the push tube 303.
[0042] Through the above embodiments, the effects achieved by the utility model are as follows: By rotating the first sleeve 2, the second sleeve 3 moves linearly accordingly, and then the extrusion ring 302 squeezes the push tube 303, causing the sealing gasket 304 to further fit the air-conditioning pipeline. When the sealing gasket 304 is further squeezed and fits the air-conditioning pipeline, the sealing performance will be significantly improved. This can effectively prevent the leakage of refrigerants, air or other fluids from the pipeline, ensure the normal operation of the air-conditioning system. The tight fit of the sealing gasket 304 can fill the tiny gaps between the pipeline and the connector, further preventing leakage.
[0043] Through all the above embodiments, the working principle of the utility model is as follows:
[0044] The air-conditioning pipeline is rotated and threadedly connected to the first threaded port 102 of the connecting tube 1. Then the first sleeve 2 threadedly connected to the threaded port is rotated again. At this time, the inner wall of the first sleeve 2 presses against the outer surface of the inclined extrusion block 203. When the first sleeve 2 applies an extrusion force to the extrusion block 203, the cushion block 204 on the side of the extrusion block 203 close to the inner wall of the connecting tube 1 fits the air-conditioning pipeline and then fastens the pipeline, which can ensure a more stable connection between the pipeline and the air-conditioning connector. By ensuring the stable connection between the pipeline and the connector, the damage to the pipeline caused by vibration or stress concentration can be reduced, thereby extending the service life of the pipeline. Further, when the first sleeve 2 is rotated and moves towards the end of the extrusion block 203, the first sleeve 2 drives the head of the second sleeve 3 to move. At this time, the extrusion ring 302 inside the opening 301 of the second sleeve 3 will squeeze the push tube 303, causing the push tube 303 to drive the sealing gasket 304 to closely fit the air-conditioning pipeline. The tight connection can reduce the loosening or displacement of the pipeline caused by vibration or temperature change, thereby improving the stability of the entire air-conditioning system. The stable connection can also reduce the noise generated by pipeline vibration and enhance the user experience. The good sealing performance can reduce the leakage of refrigerants, thereby improving the energy efficiency of the air-conditioning system.
