When the movable sleeve 8 moves toward the inside of the positioning assembly sleeve 3, the movable sleeve 8 will squeeze the surface of the sealing ring 5, and a sealed space is formed between the movable sleeve 8 and the pipe body to ensure the sealing of the inside of the pipe body after the movable sleeve 8 is connected, the right end of the movable sleeve 8 is fixedly connected to the left connection of the right half end of the pipe body, and when the movable sleeve 8 moves, it will pull the right half end of the pipe body to move toward the left half.

[0028] The tube body includes an outer layer 1 and an inner layer 2. The outer layer 1 and the inner layer 2 are of different colors to facilitate clearer separation of the outer layer 1 from the inner layer 2. The outer layer 1 is corrugated. A plurality of cavities are provided between the outer layer 1 and the inner layer 2. A pressure ring 4 is installed inside the cavity. The pressure ring 4 can prevent the cavity at the connection from being repeatedly folded, thereby reducing damage to the tube body.

[0029] The positioning combination sleeve 3 includes a fixing sleeve 31 that is sleeved on the outer side of the left half end of the outer layer 1, and a limited fixing sleeve 32 is installed on the outer side of the fixing sleeve 31. The inner side wall of the track groove at the left end of the limited fixing sleeve 32 is slidably connected with the outer side of the convex ring 34. The convex ring 34 is installed on the outer side of the left end of the rotating cylinder 33, and the inner side surface of the limiting groove at the middle end of the rotating cylinder 33 is slidably connected with the outer side of the limiting ring 37. The limiting ring 37 is installed on the outer side of the intermediate sleeve ring 36. An internal thread 6 is provided on the inner side of the right end of the rotating cylinder 33, and the internal thread 6 is connected to the external thread 7 on the movable sleeve 8. The rotating cylinder 33 can rotate inside the fixing sleeve 31 and the limited fixing sleeve 32, and the convex ring 34 and the limiting ring 37 play a limiting role in the rotation of the rotating cylinder 33. Through the interaction between the internal thread 6 and the external thread 7 of the rotating cylinder 33, the rotation of the rotating cylinder 33 will drive the movable sleeve 8 to move toward the inside of the positioning combination sleeve 3, thereby quickly connecting the pipe bodies at both ends together, and the operation process is simple, which increases the convenience of use.

[0030] The bottom of the inner ring of the front cross-section of the fixed sleeve 31 is a semicircular structure, and the two sides of the bottom of the inner ring are arc-shaped edges, and the curvature of the arc-shaped edges is the same as the curvature of the corrugated convex edge of the outer layer 1. The bottom of the fixed sleeve 31 is fixed in the corrugated groove of the outer layer 1, and the arc-shaped edge of the bottom of the fixed sleeve 31 fits on the corrugated arc-shaped convex edge of the outer layer 1. A pressure ring 4 is installed inside the cavity between the fixed sleeve 31 and the inner ring 51, and the pressure ring 4 supports the cavity between the fixed sleeve 31 and the inner ring 51. When the fixed sleeve 31 is pulled by an external force, the cavity between the fixed sleeve 31 and the inner ring 51 will be squeezed by the external force. With the support of the pressure ring 4, the corrugated frame of the outer layer 1 will not fold, thereby reducing the external force. The pressure ring 4 is squeezed onto the pressure-bearing ring 4, the inner diameter of the pressure-bearing ring 4 is equal to the spacing distance between the left and right ends of the cavity, the overall diameter of the pressure-bearing ring 4 is equal to the inner diameter of the corrugated convex groove of the outer layer 1, the pressure-bearing ring 4 can be just installed inside the outer layer 1, the bottom of the fixed sleeve 31 is tightly fitted on the outside of the outer layer 1, when the rotating cylinder 33 and the movable sleeve 8 are connected together by rotation, the rotating cylinder 33 will generate a reaction pulling force on the fixed sleeve 31 and the limiting fixed sleeve 32 during the rotation process, and the fixed sleeve 31 will be squeezed on the outer layer 1 by the external force. With the support of the pressure-bearing ring 4, the corrugated frame of the outer layer 1 will not be folded, preventing the corrugated outer layer 1 from being folded when subjected to external force.

[0031] The sealing ring 5 is composed of an inner ring 51 and an outer ring 52. The inner ring of the inner ring 51 is an arc structure in the front view section, and the arc edge is fitted on the side of the corrugated arc groove of the outer layer 1. The outer ring of the inner ring 51 is an arc plane, and the outer ring 52 is fixed to the outside of the inner ring 51. The number of outer rings 52 is plural, and the raw material of the outer ring 52 is rubber. The outer side of the outer ring 52 is fitted and connected to the inner side of the movable sleeve 8. The volume of the inner ring 51 is larger than that of the outer ring 52. The arc edge of the inner ring 51 is fitted on the side of the corrugated arc groove of the outer layer 1. The movable sleeve 8 will not change the position of the inner ring 51 when it rotates, but in the process of moving toward the inside of the rotating drum 33, the outer ring 52 will be compressed, and multiple outer rings 52 are tightly fitted together with the movable sleeve 8 to prevent the connection space from being unsealed.

[0032] The inner wall of the movable sleeve 8 is an inclined edge 81, the opening at the left end of the movable sleeve 8 is larger than the right end, and the inclined edge 81 is inclined from the opening to the right end. As the movable sleeve 8 enters the inner distance of the rotating drum 33, the pressure of the movable sleeve 8 on the outer ring 52 will increase, and the sealing degree between the outer ring 52 and the movable sleeve 8 will increase.

[0033] The right end of the movable sleeve 8 is fixedly connected to the left end of the retaining ring 9, the side surface of the retaining ring 9 is slidably connected to the side wall of the retaining groove inside the fixed disk 10, the right end of the fixed disk 10 is fixedly connected to the left connecting port of the right half of the tube body, the retaining ring 9 has the same shape as the retaining groove, and the front cross-section of the retaining ring 9 and the retaining groove are both "L"-shaped structures. The movable sleeve 8 can rotate along the retaining groove inside the fixed disk 10 through the retaining ring 9, and the rotation of the movable sleeve 8 will not affect the movement of the fixed disk 10 pulling the right half of the tube body.

[0034] When in use, the internal thread 6 of the rotating cylinder 33 is connected with the external thread 7 on the movable sleeve 8. By rotating the rotating cylinder 33, the distance that the movable sleeve 8 enters into the interior of the rotating cylinder 33 increases, and the left half end and the right half end of the tube body will be connected together. The inner side wall of the movable sleeve 8 is an inclined edge 81. As the distance that the movable sleeve 8 enters into the interior of the rotating cylinder 33 increases, the pressure of the movable sleeve 8 on the outer ring 52 will increase, and the sealing degree between the outer ring 52 and the movable sleeve 8 will increase. At the same time, the movable sleeve 8 enters into the interior of the rotating cylinder 33, and the movable sleeve 8 pulls the right half end of the tube body to the left through the fixed plate 10, and the left half end and the right half end of the tube body are connected together. The operation process is relatively simple, and the installation method makes the corrugated tube body highly sealed.
