[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a gas bellows pipe that is easy to install and connect, such as Figures 1 to 4 As shown, the device includes several corrugated pipe bodies 1. A connecting sleeve 2 is connected to two adjacent corrugated pipe bodies 1. The connecting sleeve 2 includes a first sleeve body 21 and a second sleeve body 22 that are hinged to each other. The first sleeve body 21 and the second sleeve body 22 are hollow semi-cylindrical structures. One end of the first sleeve body 21 is connected to a first positioning ring 4, and the other end is connected to a second positioning ring 5. The first positioning ring 4 and the second positioning ring 5 match the troughs 11 of the corrugated pipe bodies 1. The first positioning ring 4 and the second positioning ring 5 are respectively fitted into the troughs 11 of the two corrugated pipe bodies 1.

[0025] In the application of this invention, a gas corrugated pipe that is easy to install and connect is used by first aligning the ends of the two corrugated pipe bodies 1 that need to be spliced ​​together, and passing them between the first sleeve 21 and the second sleeve 22. Then, the first sleeve 21 is fitted onto the two corrugated pipe bodies 1 and locked. After that, the first positioning ring 4 and the second positioning ring 5 are respectively fitted into the troughs 11 of the two corrugated pipe bodies 1, thus completing the splicing of the two corrugated pipe bodies 1. Compared with the prior art, the gas corrugated pipe that is easy to install and connect is simple to operate, convenient to install, and the connection structure between the two corrugated pipe bodies 1 is more stable.

[0026] The middle part of the connecting sleeve 2 is provided with an annular boss 3, and the two bellows bodies 1 are connected on the two sides of the annular boss 3 respectively. The annular boss 3 comprises a first boss body 32 and a second boss body 33. The first boss body 32 is located in the first sleeve body 21, and the second boss body 33 is located in the second sleeve body 22. The first boss body 32 is connected to the second boss body 33. By arranging the annular boss 3 in the middle part of the connecting sleeve 2, the lengths of the two bellows bodies 1 arranged in the connecting sleeve 2 are as same as possible, so that the stability difference of the connecting structure of the two bellows bodies 1 and the connecting sleeve 2 is small, and the situation that one bellows body 1 falls off due to insufficient stability is not easy to occur.

[0027] The connecting sleeve 2 is provided with a convex pad 8 matched with the corrugation of the bellows body 1. The boss 3 is arranged on the convex pad 8 and forms two annular grooves 31 matched with the bellows body 1 with the convex pad 8. The two annular grooves 31 are arranged back to back. The convex pad 8 is a rubber pad for protecting the bellows body 1, so that the bellows body 1 is not easy to be damaged due to friction with the connecting sleeve 2, and the sealing between the bellows body 1 and the connecting sleeve 2 is enhanced.

[0028] The first sleeve body 21 is provided with a first limiting rotating shaft 211 and a second limiting rotating shaft 212. The first positioning ring 4 is rotationally connected to the first limiting rotating shaft 211, and the second positioning ring 5 is rotationally connected to the second limiting rotating shaft 212.

[0029] As shown in Figure 3 and Figure 4 , the first limiting rotating shaft 211 comprises a first rotating shaft 211a and a first limiting rod 211b. The first rotating shaft 211a and the first limiting rod 211b are parallel to each other and perpendicular to the bellows body 1. The first positioning ring 4 comprises a first sleeve ring 41 and a first connecting rod 42. The first sleeve ring 41 is a partial circular ring structure matched with the curvature of the trough 11 of the bellows body 1. One end of the first connecting rod 42 is connected to the top of the first sleeve ring 41, and the other end is provided with a first limiting block 43 and a first rotating hole. The first rotating hole is rotationally connected to the first rotating shaft 211a. The first limiting rod 211b is located on the side of the first rotating shaft 211a away from the bellows body 1. When the first sleeve ring 41 is rotated to the position that the first limiting block 43 abuts against the first limiting rod 211b, the first positioning ring 4 is limited to rotate away from the bellows body 1.

[0030] The second sleeve body 22 is provided with a third positioning ring 6 and a fourth positioning ring 7 at the two ends respectively. The third positioning ring 6 is opposite to the first positioning ring 4, and the fourth positioning ring 7 is opposite to the second positioning ring 5.

[0031] The second sleeve body 22 is provided with a third limiting rotating shaft 221 and a fourth limiting rotating shaft 222. The third positioning ring 6 is rotationally connected to the third limiting rotating shaft 221, and the fourth positioning ring 7 is rotationally connected to the fourth limiting rotating shaft 222.

[0032] The second positioning ring 5 is rotationally connected with the second limiting rotating shaft 212, the third positioning ring 6 is rotationally connected with the third limiting rotating shaft 221, the fourth positioning ring 7 is rotationally connected with the fourth limiting rotating shaft 222, and the connection mode is the same as that of the first limiting rotating shaft 211 and the first positioning ring 4, which will not be repeated here.

[0033] At least one hinge 9 is sleeved on the first sleeve body 21 and the second sleeve body 22, the hinge 9 is used for fixing the first sleeve body 21 and the second sleeve body 22, the hinge 9 is sleeved and fixed on the outer periphery of the first sleeve body 21 and the second sleeve body 22, and is fixed through a nut.

[0034] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
