[0033] Referring to Figures 1 to 4 , according to the anti-detachment pipeline installation structure of the first aspect embodiment of the present utility model, it includes a first pipeline 100, a second pipeline 200, a seat body 300, a connecting member 400, and a limiting structure 500. The connecting member 400 is detachably installed on the seat body 300. The first pipeline 100 is slidably disposed in the connecting member 400. The second pipeline 200 is connected to the connecting member 400. The first pipeline 100 and the second pipeline 200 are communicated through the connecting member 400. The limiting structure 500 includes a plugging member 510. The plugging member 510 can be plugged into the seat body 300 and the connecting member 400, which can limit the connecting member 400 from detaching from the seat body 300, and the plugging member 510 can abut against the first pipeline 100 to limit the first pipeline 100 from detaching from the connecting member 400. An external connecting pipe is connected to the first pipeline 100. Connecting members 400 of different specifications can be adapted to different pipe diameters. The connecting member 400 can be detachably replaced and installed, and the first pipeline 100 can slide and adjust its position at the connecting member 400. When the external connecting pipe is in a fixed position, the position of the first pipeline 100 can be adjusted for docking. During use, first pre-assemble the connecting member 400, the seat body 300, and the first pipeline 100, and then the plugging member 510 can limit the connecting member 400 and the first pipeline 100 from detaching, which is convenient for installation on the heat exchanger.

[0034] Specifically, the first pipe 100 can be set as a copper pipe for connecting with an external connecting pipe. The second pipe 200 can be a heat exchange coil. The seat body 300 can be used for installing on a heat exchanger. The connector 400 can be respectively butted with the first pipe 100 and the second pipe 200 to achieve connection. And the connector 400 is detachably installed on the seat body 300. Therefore, the connector 400 can be replaced with different specifications to adapt to different external pipes. It can be understood that the pipe diameter at one end of the connector 400 can be processed into different sizes to adapt to the first pipe 100 with different sizes. Thus, the first pipe 100 can adapt to external connecting pipes with different sizes. And the first pipe 100 and the connector 400 can be slidably connected. The first pipe 100 can slide along its axial direction to adjust its position. When the position of the external connecting pipe is fixed, the first pipe 100 can be adjusted to be butted with it without adjusting the position of the entire heat exchanger, which can improve compatibility. The limiting structure 500 can prevent the first pipe 100 and the connector 400 from detaching from the seat body 300. By inserting the plug-in part 510 into the seat body 300 and the connector 400, the detachment of the connector 400 from the seat body 300 can be restricted. And the plug-in part 510 can abut against the first pipe 100 to prevent the first pipe 100 from detaching from the connector 400, which is convenient for assembly and not easy to fall off during use.

The first through hole 420 can communicate the first pipe 100 with the second pipe 200. Through the above structure, the first pipe 100 can telescopically slide to adjust the position, and the connector 400 can be replaced according to requirements, which can improve the compatibility of the connection.

[0036] Specifically, the first sliding groove 410 can be set to a cylindrical shape. The bottom wall of the first sliding groove 410 is provided with a first through hole 420 penetrating axially. The first through hole 420 can communicate the first pipeline 100 with the second pipeline 200. It can be understood that one end of the connecting piece 400 away from the first sliding groove 410 can be inserted into the second pipeline 200, while the first pipeline 100 can be inserted into the first sliding groove 410 and can slide along the first sliding groove 410 to adjust the position, so that the first pipeline 100 can telescopically connect with an external connecting pipe, can adjust the position, and has good compatibility. It can be understood that the first pipeline 100 and the first sliding groove 410 have a sealing structure, which can make it both slide and seal. The specific sealing structure will not be described in detail here. And the inner diameter of the first sliding groove 410 of the connecting piece 400 can be processed into different sizes to adapt to different pipelines, and the connecting piece 400 can be replaced according to needs to further improve the compatibility.

The first sealing ring 120 has elasticity and can both seal the gap between the first pipeline 100 and the first sliding groove 410 and enable the first pipeline 100 to slide relative to the first sliding groove 410.

[0038] It can be understood that an elastic member in the shape of a sleeve can also be provided to replace the first sealing ring 120.
