[0031] The sliding sleeve 9 is slidably connected to the surface of the sliding rod 8, one side surface of the sliding sleeve 9 is fixedly connected with the return spring 10, the side surface of the return spring 10 away from the sliding sleeve 9 is fixedly connected with the sliding groove 7, the return spring 10 is connected with the sliding rod 8 in a sleeved manner, and the top surface of the sliding sleeve 9 is fixedly connected with the connecting sleeve 2. Figure 5 As shown, when the first connecting pipe 1 and the second connecting pipe 5 need to be connected, the connecting sleeve 2 is pulled to drive the sliding sleeve 9 to slide on the sliding rod 8, the movement of the sliding sleeve 9 enables the return spring 10 to be pressed, so that the return spring 10 deforms, and after the connecting box 3 is driven by the connecting sleeve 2 to move to a certain position, the end of the first connecting pipe 1 is exposed, which can more conveniently and intuitively threadedly connect the second connecting pipe 5 with the first connecting pipe 1, so that the first connecting pipe 1 and the second connecting pipe 5 are tightly connected, after the first connecting pipe 1 and the second connecting pipe 5 are connected, the connecting sleeve 2 is loosened, the connecting sleeve 2 is restored to the original position under the action of the return spring 10, so that the connecting box 3 can cover the connection between the first connecting pipe 1 and the second connecting pipe 5, and then the pressing assembly 4 is rotated to clamp and press the first connecting pipe 1 and the second connecting pipe 5, so that the threaded connection part of the first connecting pipe 1 and the second connecting pipe 5 is more compact.

[0032] Working principle: Before using the interface sealing structure of the water inlet connecting pipe, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 5As shown, first by setting the pressing assembly 4, when connecting the first connecting pipe 1 and the second connecting pipe 5, the sealing ring 6 on the second connecting pipe 5 is tightly fitted with the first connecting pipe 1 after the second connecting pipe 5 is threadedly connected with the first connecting pipe 1, so that the sealing between the first connecting pipe 1 and the second connecting pipe 5 is improved. After the first connecting pipe 1 and the second connecting pipe 5 are connected, the screw rod 403 is rotated, and the screw rod 403 and the fixed block 402 are threadedly connected. This allows the screw rod 403 to move when it is rotated. The screw rod 403 and the sliding plate 404 are connected through a bearing seat, so that the screw rod 403 does not drive the sliding plate 404 to rotate when it is rotated. When the screw rod 403 descends, it can drive the sliding plate 404 to descend. The descent of the sliding plate 404 can drive the two pressing blocks 410 to descend. After the pressing blocks 410 descend to a certain extent, the pressing block 410 above the first connecting pipe 1 contacts the first connecting pipe 1, and the pressing block 410 above the second connecting pipe 5 does not contact the second connecting pipe 5. At this time, the screw rod 403 is continuously rotated to drive the sliding plate 404 to continuously descend. During the descent of the sliding plate 404, the pressing block 410 in contact with the first connecting pipe 1 rises under the interaction force. The pressing block 410 has a movable groove 411 on its surface, and a stable block 412 is slidably connected in the movable groove 411. This allows the pressing block 410 to rise. When the pressing block 410 in contact with the first connecting pipe 1 rises, it extrudes the sliding plate 404, so that the sliding plate 404 moves under the extrusion force of the pressing block 410 in contact with the first connecting pipe 1. When the sliding plate 404 moves, it extrudes the compression spring 406 on one side of the pressing block 410 above the second connecting pipe 5, so that the compression spring 406 deforms. After the sliding plate 404 moves, it extrudes the pressing block 410 above the second connecting pipe 5, so that the pressing block 410 above the second connecting pipe 5 descends under the extrusion force, and the pressing block 410 above the second connecting pipe 5 extrudes the second connecting pipe 5, so that the threaded connection part of the first connecting pipe 1 and the second connecting pipe 5 is more tightly connected, the connection loosening caused by factors such as pressure fluctuation and vibration in the pipe is reduced, and the reliability and overall strength of the connection are improved.

[0033] Secondly, by setting the chute 7, slide 8, slide 9 and return spring 10, when the first connecting pipe 1 and the second connecting pipe 5 need to be connected, by pulling the connecting sleeve 2, the connecting sleeve 2 can drive the slide 9 to slide on the slide 8, by the movement of the slide 9, the return spring 10 is extruded, so that the return spring 10 is deformed, and after the connecting sleeve 2 drives the connecting box 3 to move to a certain position, the end of the first connecting pipe 1 leaks out, which can more conveniently and intuitively thread the second connecting pipe 5 with the first connecting pipe 1, so that the first connecting pipe 1 and the second connecting pipe 5 are connected tightly, after the first connecting pipe 1 and the second connecting pipe 5 are connected, by loosening the connecting sleeve 2, the connecting sleeve 2 is restored to the original position under the action of the return spring 10, so that the connecting box 3 can cover the connecting part of the first connecting pipe 1 and the second connecting pipe 5, then by rotating the pressing assembly 4, the pressing assembly 4 can clamp and extrude the first connecting pipe 1 and the second connecting pipe 5, so as to ensure that the threaded connection part of the first connecting pipe 1 and the second connecting pipe 5 is more tightly.

[0034] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
