[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application provides a bellows connection structure, such as Figures 1 to 5 As shown, the system includes a first corrugated pipe 1 and a second corrugated pipe 2. One end of the first corrugated pipe 1 is provided with a first connector 3. The first connector 3 includes a first connecting pipe body 31 and a first slot 32. The first slot 32 is arranged around the inner circumference of the first connecting pipe body 31 and includes an elastic inner groove wall 321. One end face of the second corrugated pipe 2 is provided with a second connector 4. The second connector 4 includes a second connecting pipe body 41 and a second slot 42. The second slot 42 is arranged around the outer circumference of the second connecting pipe body 41 and includes an elastic outer groove wall 421. The opening of the first slot 32 and the opening of the second slot 42 are arranged opposite to each other. The elastic outer groove wall 421 is used to compress the elastic inner groove wall 321, so that the second connecting pipe body 41 passes into the first connecting pipe body 31. The elastic outer groove wall 421 and the elastic inner groove wall 321 can rebound after separation, so that the elastic outer groove wall 421 passes into the first slot 32.

[0024] In the use of the corrugated pipe connection structure of this application, the first connecting pipe body 31 is inserted into the second connecting pipe along its length. When the elastic outer wall abuts against the elastic inner wall, the elastic outer wall and the elastic inner wall will squeeze each other. The elastic outer groove wall 421 shifts towards the second slot 42, the elastic inner groove wall 321 shifts towards the first slot 32, and the elastic outer groove wall 421 shifts towards the second slot 42 to form a space sufficient for the second slot 42 to pass through. When the second connecting pipe moves to the point where the elastic outer groove wall 421 disengages from the elastic inner groove wall 321, the elastic outer groove wall 421 and the elastic inner groove wall 321 can rebound to their positions before being squeezed, with the elastic outer groove wall 421 facing the first slot 32. At this time, the second connecting pipe moves away from the first connecting pipe. Figure 2 and Figure 3 As shown, the elastic outer groove wall 421 passes through the first slot 32, and the elastic inner groove wall 321 passes through the second slot 42, completing the connection between the first corrugated pipe 1 and the second corrugated pipe 2. Compared with the prior art, the corrugated pipe connection structure of this application can connect two corrugated pipes more conveniently.

[0025] As Figure 4 shown, the first connecting pipe body 31 is coaxially arranged with the first bellows 1, the elastic inner groove wall 321 is annular structure and is arranged on the inner periphery of the first connecting pipe body 31, the first insertion groove 32 is specifically formed by the elastic inner groove wall 321 and the inner wall of the first connecting pipe body 31, the second connecting pipe is coaxially arranged with the second bellows 2, the elastic outer groove wall 421 is annular structure and is arranged on the outer periphery of the second connecting pipe body 41, the second insertion groove 42 is specifically formed by the elastic outer groove wall 421 and the outer wall of the second connecting pipe body 41, the cross-sectional diameter of the elastic outer groove wall 421 is greater than the cross-sectional diameter of the elastic inner groove wall 321, and the cross-sectional diameter of the elastic outer groove wall 421 is the same as the cross-sectional diameter of the first insertion groove 32.

[0026] The first connecting pipe body 31 is formed with a first channel 311, the first end of the first channel 311 is connected to the elastic inner groove wall 321, and the second end faces the second bellows 2. The cross-sectional diameter of the first channel 311 gradually decreases in the direction from the first end to the second end. Specifically, the cross-sectional diameter of the first end is not less than the cross-sectional diameter of the second connecting pipe body 41. In this way, the second connecting pipe body 41 is aligned with the first connecting pipe body 31, and the second connecting pipe is arranged in the second connecting pipe body 41 along the central axis direction.

[0027] The first channel 311 is formed with a first arc-shaped transition structure 311a, the first arc-shaped transition structure 311a is connected between the first end and the second end and is smoothly connected with the elastic inner groove wall 321. The second connecting pipe body 41 is formed with a second arc-shaped transition structure 411, the second arc-shaped transition structure 411 is connected between the elastic outer groove wall 421 and the pipe opening of the second connecting pipe body 41 facing the first connecting pipe body 31. The second arc-shaped transition structure 411 is used to cooperate with the first arc-shaped transition structure 311a to make the first connecting pipe body 31 arranged in the first connecting pipe body 31. Specifically, the first arc-shaped transition structure 311a is a first annular arc surface, and the second arc-shaped transition structure 411 is a second annular arc surface. In the use process of the bellows connecting structure, the arc surface of the second arc-shaped transition structure 411 is attached to the first arc-shaped transition structure 311a and slides along the first arc-shaped transition structure 311a. The elastic outer groove wall 421 further enters the first connecting pipe body 31 and is not easy to be stuck due to the cross-sectional diameter of the elastic outer groove wall 421 being greater than the cross-sectional diameter of the elastic inner groove wall 321.

[0028] As Figure 5As shown, the second connecting pipe body 41 is formed with a boss and a third arc-shaped transition structure 412, the boss is arranged on the side of the second connecting pipe body 41 away from the first connecting pipe body 31, and the third arc-shaped transition structure 412 is connected between the outer wall of the second connecting pipe body 41 and the boss, and is used to cooperate with the first arc-shaped transition structure 311a to enable the first connecting pipe body 31 to be inserted into the first connecting pipe body 31. Specifically, the third arc-shaped transition structure 412 is a third annular arc surface, which matches the first annular arc surface. The distance from the boss to the slot of the second slot 42 is not less than the distance from the second end of the first channel 311 to the slot of the first slot 32. During the use of the corrugated pipe connecting structure, the elastic outer groove wall 421 moves along the length direction of the first connecting pipe body 31 towards the first corrugated pipe 1, the first arc-shaped transition structure 311a is in contact with the third arc-shaped transition structure 412 after being separated from the second arc-shaped transition structure 411, and the second end of the first channel 311 abuts on the boss until the elastic outer groove wall 421 is inserted into the first slot 32 in the direction away from the first corrugated pipe 1. In this way, the user can clearly determine the rebounding time of the elastic outer groove wall 421 and the elastic inner groove wall 321, and can insert the elastic outer groove wall 421 into the first slot 32 according to the rebounding time.

[0029] The elastic inner groove wall 321 is formed with a rounded structure 321a, and the end of the elastic outer groove wall 421 close to the slot is provided with a convex ring 422, which is used to cooperate with the rounded structure 321a to enable the elastic outer groove wall 421 to be inserted into the first slot 32. The rounded structure 321a is specifically an inclined structure towards the first slot 32, and the cross-sectional size of the convex ring 422 is greater than the cross-sectional size of the first slot 32. In this way, when the convex ring 422 contacts the rounded structure 321a, it can be clamped into the first slot 32 under the guidance of the rounded structure 321a.

[0030] The first connecting pipe body 31 is also provided with a sealing element, which is embedded with the second corrugated pipe 2. Specifically, the sealing element includes a mounting pipe and a plurality of sealing rings 312. The mounting pipe is coaxially connected with the first connecting pipe body 31 and located at the end of the first connecting pipe body 31 towards the second connecting pipe body 41. The plurality of sealing rings 312 are uniformly arranged in the mounting pipe along the length direction of the mounting pipe. The interval distance between the adjacent two sealing rings 312 is the same as the interval distance between the adjacent two wave crests of the second corrugated pipe 2. During the use of the corrugated pipe connecting structure, the plurality of sealing rings 312 are clamped one by one between the adjacent two wave crests of the second corrugated pipe 2.
