[0003] In the existing technology, when using crimp fittings, because there are many crimping grooves on the crimp fittings, if the crimping grooves are not aligned accurately, it will result in low pipe connection stability and insufficient sealing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] like Figure 1-6As shown, connector 1 and connector 4 are detachably connected to clamping member 2; the two clamping members 2 are internally threaded to the rotating member 3; the clamping member 2 includes a locking internal thread 201, a clamping ring 202, a circumferential limiting groove 203, and a telescopic component 204; the front end of the clamping ring 202 is provided with an array of telescopic components 204 that are movably connected to connector 1, the gaps between the telescopic components 204 are provided with circumferential limiting grooves 203, and the rear end of the clamping ring 202 is provided with a locking internal thread 201 that is connected to one end of the rotating member 3;

[0032] The telescopic assembly 204 includes a telescopic spring 2041 and a telescopic limiting block 2042; the front end of the clamping ring 202 is provided with a telescopic groove; the telescopic spring 2041 is provided on the telescopic groove; the front end of the telescopic spring 2041 is provided with a telescopic limiting block 2042; the front end of the telescopic limiting block 2042 is a rectangular block and the rear end is a triangular block; the connecting member 1 and the connecting member 2 are respectively provided with clamping members 2 with the same pitch and opposite thread directions;

[0033] The connector 1 includes a horizontal limiting groove, a circumferential limiting block 102, a connector 103, and a pipe 104. The connector 103 is provided at the front end of the pipe 104, and the horizontal limiting groove is provided on the pipe 104. A plurality of circumferential limiting blocks 102 are arranged in an array on the horizontal limiting groove. The cross-section of the horizontal limiting groove is triangular and its size is the same as that of the rear end of the telescopic limiting block 2042. The size and number of the circumferential limiting blocks 102 are the same as those of the circumferential limiting groove 203.

[0034] The rotating component 3 includes a rotating cylinder 301, a locking external thread 302, and a sealing ring 303; both ends of the rotating cylinder 301 are provided with external threaded connection buckle rings 202, and the sealing ring 303 is provided in the middle of the interior of the rotating cylinder 301 to rotatably connect connector 1 and connector 2; the inner diameter of the rotating component 3 is slightly smaller than the outer diameter of connector 1, the outer diameter of the rotating component 3 is slightly smaller than the inner diameter of buckle 2, and the thickness of the rotating component 3 is the same as the length of the horizontal right angle side of the triangular block at the rear end of the telescopic limiting block 2042;

[0035] In this embodiment, when the device is in use, the two clamping parts 2 are connected to the rotating part 3 by threads, and the clamping parts 2 are respectively installed on the connector 1 and connector 4 at both ends. When the telescopic limiting block 2042 is aligned with the horizontal limiting groove, under the elastic reset action of the spring, the telescopic limiting block 2042 is pushed out and inserted into the horizontal limiting groove, thus completing the connection between the clamping part 2 and the connector. After the connection is completed, the rotating cylinder 301 is rotated, and the clamping parts 2 with the same thread pitch on both sides but opposite rotation directions are driven by the clamping parts 2 on both sides to bring the connector closer together, so that the connector 103 is connected and sealed by the sealing ring 303, thereby achieving the purpose of connecting the pipeline and solving the problems of low pipeline connection stability and insufficient sealing.

[0036] Meanwhile, the distance between the two clamping parts 2 can be adjusted by rotating the rotating cylinder 301, thereby adjusting the tightness of the pipe connection and preventing the connection from being too tight or too loose. This solves the problem in the prior art where the device is not adjustable, which leads to the pipe being damaged by being too tight or the connection being too loose.

[0037] In this embodiment, the device, through the design of the telescopic component 204 and the rotating component 3, allows the connectors to be fixed together more tightly, reducing leakage or damage caused by unstable connection. The design allows the tightness of the connection to be adjusted by simple rotation, making the installation and adjustment process faster and more convenient. The design of the rotating component 3 provides the adjustability of the connection, which can adjust the tightness of the pipe connection according to actual needs, preventing the problem of connection being too tight or too loose.

[0038] In this embodiment, after the connection is completed, both ends of the rotating cylinder 301 extend into the cavity of the telescopic limiting block 2042 inside the clamping ring 202. At this time, the inner surface of the rotating cylinder 301 is in contact with the vertical right-angle side of the triangular block at the rear end of the telescopic limiting block 2042, thereby limiting the telescopic limiting block 2042 and preventing the telescopic limiting block 2042 from retracting into the telescopic groove, thus causing the connection to become loose.

[0039] In summary, this utility model provides clamping elements 2 on connector 1 and connector 2 respectively. A telescopic spring 2041 compresses the telescopic limiting block 2042 into the horizontal limiting groove. Simultaneously, the circumferential limiting block 102 cooperates with the circumferential limiting groove 203 to restrict the circumferential rotation of the clamping ring 202. A rotating element 3 provides a threaded connection. By rotating the rotating element 3, since the locking internal threads 201 on both sides have the same pitch but opposite directions, the clamping elements 2 on both sides pull connector 1 and connector 2 relative to each other, connecting them through the connector head 103. This connects the pipeline, and the sealing ring 303 seals the connection, improving its stability and sealing performance. Simultaneously, rotating the rotating element 3 adjusts the tightness of the connection.
