[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. By providing the connecting pipe, the rotating ring, the threaded pipe and the rubber ring, since threads are provided inside both connecting pipes, when the two connecting pipes rotate along the outer surfaces of the two threaded pipes, it will drive the two rotating rings and the two rubber rings to move away from each other along the inside of the round block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 6 shown, the present utility model provides a corrugated pipe connection structure, including:

[0030] The circular block 1 has fixed rings 2 fixedly installed on both the left and right sides inside the circular block 1;

[0031] The connecting mechanism is arranged inside the circular block 1;

[0032] Among them, the connecting mechanism includes connecting pipes 3. The number of connecting pipes 3 is two. The outer surfaces of both connecting pipes 3 are movably sleeved with the inside of the circular block 1. One end of each of the two connecting pipes 3 facing away from each other penetrates through the inside of the circular block 1 and extends to the outside of both sides of the circular block 1. The outer surfaces of one end of each of the two connecting pipes 3 facing each other are fixedly sleeved with rotating rings 4. The number of rotating rings 4 is two. One end of each of the two rotating rings 4 facing away from each other is movably connected to the outer surface of the fixed ring 2. The outer surfaces of both rotating rings 4 are movably sleeved with the inside of the circular block 1. Bellows 5 are movably sleeved inside both connecting pipes 3. Threaded pipes 6 are threadedly sleeved inside one end of each of the two connecting pipes 3 facing away from each other.

[0033] Since threads are provided inside both connecting pipes 3, when the two connecting pipes 3 rotate along the outer surfaces of the two threaded pipes 6, they will move away from each other. At this time, the two connecting pipes 3 will drive the two rotating rings 4 to move away from each other. During this process, the inside of the two connecting pipes 3 will be movably sleeved with the outer surfaces of the two bellows 5. At this time, the two bellows 5 will be connected to the inside of the two connecting pipes 3 through the circular block 1. Since the outer surfaces of the two rotating rings 4 are always movably sleeved with the inside of the circular block 1, the sealing performance between the circular block 1 and the two connecting pipes 3 is ensured.

[0034] Among them, one end of each of the two rotating rings 4 facing away from each other is fixedly installed with a rubber ring 7. The outer surface of the rubber ring 7 is movably connected to the outer surface of the fixed ring 2.

[0035] Due to the design of the two rubber rings 7, when the two rubber rings 7 come into contact with the two fixed rings 2, the sealing performance between the circular block 1 and the two connecting pipes 3 will be enhanced.

[0036] Among them, a rubber ring 8 is fixedly sleeved inside the connecting pipe 3. The inside of the rubber ring 8 is movably sleeved with the outer surface of the bellows 5.

[0037] Due to the design of the two rubber rings 8, the sealing performance between the two bellows 5 and the two connecting pipes 3 will be enhanced.

[0038] Among them, a circular plate 9 is fixedly sleeved on the outer surface of the threaded pipe 6. A limiting groove 10 is opened on the outer surface of the circular plate 9.

[0039] Due to the design of the eight limiting grooves 10, the object located inside it will be limited, so that it can only move along the inside of the limiting groove 10.

[0040] Among them, the other end of the threaded pipe 6 is fixedly installed with a circular pipe 11, and the other end of the circular pipe 11 is fixedly installed with a circular ring 12.

[0041] Since the outer surfaces of both of the two circular tubes 11 are provided with threads, when an object rotates along its outer surface, it will move left and right.

[0042] Wherein, a rotating ring 13 is threadedly sleeved on the outer surface of the circular tube 11, and a movable ring 14 is fixedly sleeved inside the rotating ring 13.

[0043] Since the inner parts of the two rotating rings 13 are respectively threadedly sleeved on the outer surfaces of the two circular tubes 11, when the two rotating rings 13 rotate along the outer surfaces of the two circular tubes 11, the two movable rings 14 will be driven to move away from each other.

[0044] Wherein, a moving ring 15 is fixedly installed on the outer surface of the movable ring 14, and the other end of the moving ring 15 penetrates through the inside of the rotating ring 13 and extends to the outside of the rotating ring 13.

[0045] When the two movable rings 14 move away from each other, at this time, the two moving rings 15 will be driven by the two movable rings 14 to move away from each other.

[0046] Wherein, a first hinge block 16 is fixedly installed inside the outer surface of the other end of the moving ring 15, and a moving rod 17 is hinged inside the first hinge block 16.

[0047] When the two moving rings 15 move away from each other, at this time, the eight first hinge blocks 16 will be driven by the two moving rings 15 to move away from each other, and at this time, the eight moving rods 17 will be driven by the eight first hinge blocks 16 to move.

[0048] Wherein, the other end of the moving rod 17 is hinged with a second hinge block 18, and the outer surface of the second hinge block 18 is movably connected with the inside of the limiting groove 10.

[0049] When the eight moving rods 17 move, at this time, the eight second hinge blocks 18 will be driven by the eight moving rods 17 to move.

[0050] Wherein, a clamping block 19 is fixedly installed at the other end of the second hinge block 18, the outer surface of the clamping block 19 is movably connected with the inside of the limiting groove 10, and the other end of the clamping block 19 penetrates through the outer surface of the threaded tube 6 and extends to the inside of the threaded tube 6.

[0051] Due to the limiting effect of the eight limiting grooves 10, when the eight second hinge blocks 18 move, at this time, the eight clamping blocks 19 will be driven by the eight second hinge blocks 18 to move inwards, and at this time, the two corrugated tubes 5 will be clamped during the inward movement of the eight clamping blocks 19.

[0052] The working principle and usage process of the present utility model:

[0053] First, the operator places two corrugated pipes inside two threaded pipes 6. At this time, the operator drives two rotating rings 13 to rotate successively. Since the inner parts of the two rotating rings 13 are respectively threadedly sleeved on the outer surfaces of the two round pipes 11, when the two rotating rings 13 rotate along the outer surfaces of the two round pipes 11, they will move away from each other. At this time, the two movable rings 14 will move away from each other under the drive of the two rotating rings 13. Immediately afterwards, the two movable rings 14 will drive eight first hinge blocks 16 to move away from each other through the two moving rings 15. Subsequently, the eight first hinge blocks 16 will drive eight moving rods 17 to move respectively. At this time, the other ends of the eight moving rods 17 will drive eight clamping blocks 19 to move through the eight second hinge blocks 18. Due to the design inside the eight limiting grooves 10, the movement of the eight clamping blocks 19 will be limited. At this time, the eight clamping blocks 19 will move inwards under the drive of the eight second hinge blocks 18. Subsequently, the eight clamping blocks 19 will clamp and fix the two corrugated pipes 5 during the inward movement, thus realizing the function of automatically clamping and fixing the two corrugated pipes 5.

[0054] Subsequently, the operator places the round block 1 as a whole between the two threaded pipes 6. At this time, the operator docks the two connecting pipes 3 and the two threaded pipes 6. Immediately afterwards, the operator rotates the two connecting pipes 3 successively. Since threads are provided inside the two connecting pipes 3, when the two connecting pipes 3 rotate, they will be threadedly sleeved on the outer surfaces of the two threaded pipes 6. At this time, the two connecting pipes 3 will drive the two rotating rings 4 to move away from each other along the inside of the round block 1. During this process, the inside of the two connecting pipes 3 will be movably sleeved on the outer surfaces of the opposite ends of the two corrugated pipes 5. At this time, the inside of the two corrugated pipes 5 will be connected through the inside of the round block 1, thus realizing the function of quickly disassembling and assembling the two corrugated pipes 5.
