DETAILED DESCRIPTION

[0034] The following is a combination of the appended examples of the present invention Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] When the pipe is in the closed position, the cam 3 is tightened to the end of the pipe 2, and the pipe 2 is tightened to the end of the pipe 2. When the pipe is in the closed position, the cam 3 is tightened to the end of the pipe 2, and the pipe 2 is tightened to the end of the pipe 2. When the pipe is in the closed position, the cam 3 is tightened to the end of the pipe 2, and the pipe 2 is tightened to the end of the pipe 2.

[0036] The groove joint 4 includes a first connection part 5 fixedly connected to the auxiliary pipe 2, the first connection part 5 is fixed with a second connection part 6, the second connection part 6 is fixed with a third connection part 7, the outer diameter of the third connection part 7 is equal to the outer diameter of the first connection part 5, and the outer diameter of the second connection part 6 is smaller than the outer diameter of the first connection part 5, so that the second connection part 6 is recessed between the first connection part 5 and the third connection part 7, wherein the second connection part 6 can be crimped into a recessed type by a crimping tool. Through this arrangement, when the external pipe passes through the groove joint 4, it will be firmly clamped by the inner wall of the second connection part 6, and of course it must be matched with a corresponding sealing ring. The arrangement of the groove joint 4 makes the installation of the pipeline convenient and quick, and also facilitates subsequent maintenance, saving costs while improving installation and maintenance efficiency.

[0037] A first transition section 8 is provided between the second connection part 6 and the first connection part 5. The first transition section 8 includes an arc-shaped convex section 9 fixedly connected to the first connection part 5. The arc-shaped convex section 9 is fixed with a vertical section 10. The vertical section 10 is fixed with a first arc-shaped concave section 11. The first arc-shaped concave section 11 is fixed with the second connection part 6. A second transition section 12 is provided between the second connection part 6 and the third connection part 7. The second transition section 12 is symmetrically arranged with the first transition section 8. Through the arrangement of the first transition section 8 and the second transition section 12 of this structure, the external pipe fittings can better enter the second connection part 6 with a relatively smaller diameter, thereby assisting extrusion.

[0038] The ring clamp joint 3 includes a first truncated cone portion 13 fixedly connected to the main pipe 1, the first truncated cone portion 13 is fixed with a first cylindrical portion 14, the first cylindrical portion 14 is fixed with an annular outer convex portion 15, the annular outer convex portion 15 is fixed with a second cylindrical portion 16, the second cylindrical portion 16 is fixed with a second truncated cone portion 17, and the second truncated cone portion 17 is fixed with a third cylindrical portion 18. The diameter of the end of the first truncated cone portion 13 connected to the main pipe 1 is smaller than the diameter of the end connected to the first cylindrical portion 14, and the diameter of the end of the second truncated cone portion 17 connected to the second cylindrical portion 16 is smaller than the diameter of the end connected to the third cylindrical portion 18. , wherein the outer diameters of the first cylindrical portion 14 and the second cylindrical portion 16 are equal, wherein the second conical portion 17 and the first conical portion 13 play a good role in limiting the caliber, and thus play a good role in squeezing and clamping the external pipe inserted into the ring clamp joint 3. The external pipe is clamped twice by the second conical portion 17 and the first conical portion 13, and the first conical portion 13 has a greater degree of squeezing and limiting the external pipe than the second conical portion 17, so that the external pipe has a good clamping and sealing effect. In addition, the second conical portion 17 and the first conical portion 13 also play a good guiding and connecting role. The annular outer protrusion 15 plays a good sealing role for the external pipe inserted therein, further improving the sealing performance. Therefore, through the setting of the ring clamp joint 3 with this structure, its structure with a larger left end and a smaller right end greatly facilitates the insertion and clamping of external pipes on the one hand, and greatly improves the sealing performance on the other hand.

[0039] The annular outer protrusion 15 includes an arc-shaped outer protrusion section 19 arranged in the middle position, and both ends of the arc-shaped outer protrusion section 19 are connected to the inclined section 20, and the lower end of the inclined section 20 is connected to the second arc-shaped recessed section 21. Through the setting of the annular outer protrusion 15, the annular outer protrusion 15 is relatively thick, which greatly improves the sealing effect on the external pipe inserted therein.

[0040] The annular outer convex portion 15 includes an annular outer convex wall body 22 and a sealing ring 23 fixed to the inner wall surface of the annular outer convex wall body 22. The inner wall surface of the sealing ring 23 extends out of the groove 24 of the annular outer convex portion 15. The annular outer convex portion 15 is configured to include an arcuate outer convex section 19, an inclined section 20, and a second arcuate recessed section 21. This configuration further secures the sealing ring 23 to the annular outer convex wall body 22. The inner wall surface of the sealing ring 23 extends out of the groove 24 of the annular outer convex portion 15. This squeezes the sealing ring 23 when the external pipe passes through it, ultimately causing the sealing ring 23 to be tightly pressed against the outer wall surface of the external pipe, thereby achieving a good sealing effect.

[0041] The inner wall diameter of the sealing ring 23 gradually decreases from left to right. This setting enables the external pipe to perform a gradual extrusion process on the sealing ring 23, which not only facilitates the passage of the external pipe, but also makes the extrusion force of the sealing ring 23 on the outer wall of the external pipe gradually increase from left to right, further improving the sealing and fixing effect of the external pipe.

[0042] The inner wall surface of the sealing ring 23 is set to be a continuous wave shape. Through this setting, on the one hand, when the external pipe passes through the sealing ring 23, the contact area between the outer wall surface of the external pipe and the inner wall surface of the sealing ring 23 is greatly reduced, thereby allowing the external pipe to pass through the sealing ring 23 more quickly. In addition, this setting forms a groove between two adjacent waves. After being squeezed, the groove is equivalent to a suction cup, which can have a good adsorption effect on the external pipe, thereby improving the sealing and fixing effect.

[0043] A plurality of rectangular grooves 25 are formed on the inner wall surface of one end of the first connecting portion 5 near the auxiliary pipe 2. A clamping mechanism 26 is provided in the rectangular groove 25. The clamping mechanism 26 includes a fixing rod 27 fixed between the two side walls of the rectangular groove 25. A clamping block 28 is rotatably connected to the fixing rod 27. A plurality of springs 29 are fixed between the top wall of the clamping block 28 and the bottom wall of the rectangular groove 25.

[0044] The clamping mechanism 26 provides a final position limiting and clamping effect on the external pipe. When the external pipe contacts the clamping block 28 during insertion into the annular outer protrusion 15, the clamping block 28 is squeezed until the spring 29 reaches its limit and the clamping block 28 cannot rotate. This further enhances the clamping and fixation of the external pipe and effectively limits the position of the external pipe, preventing unnecessary trouble caused by the insertion of the external pipe into the auxiliary pipe 2. The clamping block 26 partially extends outside the rectangular groove 25, and the bottom surface of the clamping block 28 is configured as an arc surface with the left side higher and the right side lower. The spring 29 is configured in an inclined shape, wherein the inclined shape of the spring 29 matches the direction of rotation of the clamping block 28 around the fixing rod 27, thereby better squeezing the spring 29 and preventing the spring 29 from twisting.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
