The fixing component 3 includes a supporting block 34, and the supporting block 34 is fixedly connected to the upper surface of the connecting ring 2. A threaded rod 33 is rotatably connected to the left surface of the supporting block 34. The threaded rod 33 is a prior art, which is a long strip object with a threaded structure, usually used to convert rotational motion into linear motion or transfer force from one point to another. The outer wall of the threaded rod 33 is threadedly connected to a fixing block 32, and the lower surface of the fixing block 32 is fixedly connected to a guide block 31, and the guide block 31 is slidably connected to the outer wall of the connecting ring 2.

[0033] Reference Figure 2 - Figure 3 The positioning assembly 4 includes a sealing block 41. The portion of the sealing block 41 that contacts the connecting ring 1 is made of rubber material, which can ensure the sealing of the connecting ring 1 and the connecting ring 2. The sealing block 41 is fixedly connected to the right surface of the connecting ring 2. The right surface of the sealing block 41 contacts the left surface of the connecting ring 1. The front surface of the sealing block 41 is fixedly connected with a positioning block 42. The positioning block 42 can ensure that the insertion rod 39 and the plug-in slot 5 are quickly positioned.

[0034] Reference Figure 1 - Figure 2A through groove 36 is provided on the front surface of the guide block 31, and the through groove 36 has a certain slope to ensure that when the guide block 31 is moved, the slide bar 35 will move upward or downward along the slope of the through groove 36, and the slide bar 35 is slidably connected to the inner wall of the through groove 36, and a through groove 2 37 is provided on the front surface of the connecting ring 2 2, and the slide bar 35 is slidably connected to the inner wall of the through groove 2 37.

[0035] Reference Figure 2 , Figure 4 - Figure 5 The fixing assembly 3 also includes an arc-shaped connecting block 38, which is adapted to the inner wall of the arc-shaped groove 7 to ensure an initial positioning and fixing function, thereby improving practicality. At the same time, the rear surface thereof is designed as an arc-shaped surface to ensure that the connection ring 1 and the connecting ring 2 2 can be quickly removed from the connection, thereby improving practicality. The arc-shaped connecting block 38 is slidably connected to the inner wall at the top of the connecting ring 2, and the rear surface of the sliding rod 35 is fixedly connected to the front surface of the arc-shaped connecting block 38. The lower surface of the arc-shaped connecting block 38 is fixedly connected with a plug rod 39, and the front surface of the plug rod 39 is fixedly connected with a rubber card block 310. The plug rod 39 contacts the inner wall of the plug-in groove 5, and the rubber card block 310 contacts the inner wall of the card-connecting groove 6. The rubber card block 310 is made of rubber material, and the rubber card block 310 has a certain elasticity. It will be deformed after being squeezed, and will immediately return to its original shape after the extrusion ends. At the same time, its upper and lower surfaces are arc-shaped surfaces, which can ensure that it can smoothly enter the inner wall of the plug-in groove 5 and be stuck in the inner wall of the card-connecting groove 6.

[0036] Reference Figure 3 The inner wall of the sealing block 41 is elastically connected to the arc block 43 through a spring 44. The spring 44 always pushes the arc block 43 backward by its own elasticity to ensure the stability of the connection of the arc block 43. The arc block 43 is slidably connected to the inner wall of the sealing block 41. One end of the spring 44 is fixedly connected to the inner wall of the sealing block 41, and the other end of the spring 44 is fixedly connected to the front surface of the arc block 43.

[0037] Reference Figure 3 An arc groove 7 is provided on the front surface of the left end of the connecting ring 1, adjacent to the right side of the plug-in groove 5, and a through groove 3 8 is provided on the left surface of the connecting ring 1. The positioning block 42 contacts the inner wall of the through groove 3 8, and the arc block 43 contacts the inner wall of the arc groove 7. The rear surface of the arc block 43 is set to an arc surface. The set arc surface ensures that the connecting ring 1 can be smoothly inserted into the inner wall of the connecting ring 2 2.

[0038] Working principle: When installing the pipeline, you only need to insert the connecting ring 1 into the inner wall of the connecting ring 2. During the insertion process, make sure that the positioning block 42 is inserted into the inner wall of the through groove 3 8. During this process, the arc block 43 will be squeezed into the inner wall of the sealing block 41, and the arc block 43 will squeeze the spring 44 to deform it until the arc block 43 and the arc groove 7 are completely overlapped. The spring 44 pushes the arc block 43 to move in the opposite direction through its own elasticity, so that the arc block 43 enters the inner wall of the arc groove 7. In this way, the plug-in groove 5 set on the upper surface of the left end of the connecting ring 1 and the plug rod 39 are completely overlapped to complete the positioning.

[0039] At this time, the threaded rod 33 can be rotated, and the fixed block 32 threadedly connected to the outer wall of the threaded rod 33 will move linearly on its outer wall, and the fixed block 32 will drive the outer wall of the guide block 31 to move. At this time, the sliding rod 35 will slide on the inner wall of the through groove 1 36 and move in the through groove 2 37 along the inclination of the through groove 1 36. The sliding rod 35 will drive the arc-shaped connecting block 38 to move, and the arc-shaped connecting block 38 will drive the plug rod 39 to move until the threaded rod 33 cannot rotate. At this time, the plug rod 39 will be completely inserted into the inner wall of the plug-in groove 5, so that the connecting ring 1 1 and the connecting ring 2 2 can be completely fixed together. In the process of the plug rod 39 inserting the inner wall of the plug-in groove 5, the rubber block 310 will be squeezed and deformed due to its own characteristics until the rubber block 310 overlaps with the card slot 6 set on the inner wall of the plug-in groove 5, and the rubber block 310 will restore its original state through its own characteristics and insert into the inner wall of the card slot 6.

[0040] When disassembling, just reverse the threaded rod 33, and the subsequent structural coordination method is the same as above, so that the insertion rod 39 and the rubber block 310 can be separated from the inner wall of the insertion groove 5, and then the connecting ring 1 or the connecting ring 2 2 can be directly pulled to separate them. When pulling, the arc block 43 will be separated from the inner wall of the arc groove 7 through its own arc surface, which is quick and convenient, and improves work efficiency.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
