[0003] The existing splicing method is usually to align two corrugated pipes or insert two corrugated pipes into each other, and then use a connecting structure to sleeve the connection part of the two corrugated pipes to splice the corrugated pipes. It is not convenient to seal the connection part layer by layer. After long-term use, the corrugated pipe deforms, and gaps will appear at the connection part of the corrugated pipe, resulting in leakage of gas or liquid inside the corrugated pipe. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is that when the existing corrugated pipes are spliced, after long-term use, gaps will appear at the connection part of the corrugated pipes, resulting in leakage of gas or liquid inside the corrugated pipes.
[0005] To solve the above technical problem, the technical scheme adopted by the utility model is as follows: A leak-proof spliced corrugated pipe includes a first corrugated pipe and a second corrugated pipe. The second corrugated pipe and the first corrugated pipe are detachably connected. The spliced component is arranged on the first corrugated pipe and the second corrugated pipe, and the first corrugated pipe and the second corrugated pipe are quickly and hermetically connected through the spliced component.
[0006] Further, the spliced component includes an outer ring, an inner ring, a first sealing ring, an insertion ring, an annular ring and a second sealing ring, wherein:
[0007] The outer ring is fixedly connected to the outer side of the end part of the first corrugated pipe. The inner ring is fixedly connected to the inner side of the end part of the first corrugated pipe. An inner groove is arranged on one side of the inner ring and is annularly arranged. The first sealing ring is fixedly connected to the inner wall of the inner groove. The insertion ring is fixedly connected to the end part of the second corrugated pipe and is adapted to the inner groove. The annular ring is fixedly connected to the outer side of the end part of the second corrugated pipe. The second sealing ring is fixedly connected to the outer side of the end part of the second corrugated pipe. One end of the outer ring is arranged between the annular ring and the second sealing ring.
[0008] Further, the spliced component further includes a square box, internal teeth, insertion rods, locking teeth, pins and locking blocks, wherein:
[0009] The square box is fixedly connected to the first corrugated pipe and the second corrugated pipe, and one side of it is open. The internal teeth are fixedly connected to the inner top and inner bottom of the square box, and are arranged linearly at equal intervals. The insertion rod is inserted into the square box. The locking teeth are fixedly connected to the insertion rod and are arranged linearly. The middle section of the insertion rod is provided with a through hole. The insertion pin is inserted into the insertion rod, and the locking block is threadedly connected to the end of the insertion pin.
[0010] Further, at least four groups of insertion rods are provided, and at least two groups of the outer side walls of the insertion rods are provided with stoppers.
[0011] Further, the locking teeth are made of an elastic material, and both the internal teeth and the locking teeth are arranged obliquely.
[0012] After adopting the above structure, the beneficial effects of the present utility model are as follows: The two corrugated pipes can be quickly butt-connected, and the connection part thereof can be stably connected, solving the problem that the connection part of the existing corrugated pipe has gaps after long-term use, resulting in the leakage of gas or liquid inside the corrugated pipe.

Detailed Embodiments
[0019] As Figures 1-3As shown in the figure, a leak-proof spliced bellows includes bellows one 1 and bellows two 2. Bellows two 2 and bellows one 1 are detachably connected, and a splicing component is also included, which is arranged on bellows one 1 and bellows two 2.
[0020] As Figures 1-4 shown in the figure, in order to quickly seal and connect bellows one 1 and bellows two 2, the splicing component includes an outer ring 3, an inner ring 4, a first sealing ring 5, an insertion ring 6, an annular ring 7, a second sealing ring 8, a square box 10, internal teeth 11, insertion rods 12, locking teeth 13, insertion pins 14 and locking blocks 15. The outer ring 3 is fixedly connected to the outer side of the end of bellows one 1, the inner ring 4 is fixedly connected to the inner side of the end of bellows one 1. An inner groove 9 is provided on one side of the inner ring 4 and is annularly arranged. The first sealing ring 5 is fixedly connected to the inner wall of the inner groove 9. The insertion ring 6 is fixedly connected to the end of bellows two 2 and is adapted to the inner groove 9. The annular ring 7 is fixedly connected to the outer side of the end of bellows two 2. The second sealing ring 8 is fixedly connected to the outer side of the end of bellows two 2. One end of the outer ring 3 is arranged between the annular ring 7 and the second sealing ring 8. The square box 10 is fixedly connected to bellows one 1 and bellows two 2, and one side of it is open.
