DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a polyethylene corrugated pipe that is easy to splice. Figure 1-5A polyethylene corrugated pipe that is easy to splice, comprising a first corrugated pipe 1, a second corrugated pipe 2, a clamping mechanism 5 and a fixed ring block 61, the outer side of the first corrugated pipe 1 is rotatably connected with a connecting block 3, the outer side of the second corrugated pipe 2 is provided with a connecting groove 14, the second corrugated pipe 2 is located inside the connecting groove 14 and is provided with a mounting block 4, the fixing ring block 61 is arranged inside the first corrugated pipe 1, and the fixing ring block 61 is fixedly connected to the first corrugated pipe 1, one side of the fixing ring block 61 is fixedly connected with a connecting ring block 62, the inside of the second corrugated pipe 2 is fixedly connected with a threaded ring block 63, and the connecting ring block 62 is threadedly connected to the inside of the threaded ring block 63, the clamping mechanism 5 is arranged on one side of the mounting block 4, and the mounting block 4 is used to connect the first corrugated pipe 1 and the second corrugated pipe 2;

[0025] In this way, during the implementation process, the first bellows 1 can smoothly install and fix the connecting block 3, and the second bellows 2 can be connected to the mounting block 4 through the connecting groove 14, so that the mounting block 4 can stably slide inside the connecting groove 14, and the first bellows 1 can also install and fix the connecting ring block 62 through the fixing ring block 61, and the second bellows 2 can be stably connected to the threaded ring block 63. After the connecting ring block 62 is rotated, it can smoothly and stably connect to the inside of the second bellows 2 through the threaded connection between itself and the threaded ring block 63, thereby realizing the connection between the first bellows 1 and the second bellows 2;

[0026] When the staff needs to connect the first bellows 1 with the second bellows 2, the staff can rotate the first bellows 1, and when the connecting ring block 62 is rotated, it can smoothly connect to the inside of the second bellows 2 by using the threaded connection between the connecting ring block 62 and the threaded ring block 63, so that the first bellows 1 and the second bellows 2 are smoothly connected together, and the circulation and connection between the first bellows 1 and the second bellows 2 are realized. When the first bellows 1 is connected to the second bellows 2 by rotation, the connecting block 3 needs to be held and limited so that the connecting block 3 does not rotate, so as to realize the subsequent connection of the connecting block 3 with the clamping mechanism 5;

[0027] The setting of the clamping mechanism 5 can smoothly increase the stability of the first bellows 1 and the second bellows 2 after the connection when the first bellows 1 and the second bellows 2 are connected to each other through the threaded connection of the connecting ring block 62 and the threaded ring block 63, thereby effectively increasing the stability and sealing of the first bellows 1 and the second bellows 2 during use when the first bellows 1 and the second bellows 2 are connected, and reducing the leakage and low sealing of the first bellows 1 and the second bellows 2 during use.

[0028] The clamping mechanism 5 includes an inserting block 51 fixedly connected to one side of the mounting block 4, a clamping slot 52 is provided on one side of the connecting block 3, the inserting block 51 is movably inserted into the inside of the clamping slot 52, a mounting slot 53 is provided on one side of the inserting block 51, a spring 54 is fixedly connected to the inserting block 51 located inside the mounting slot 53, a clamping block 55 is fixedly connected to one end of the spring 54, and the clamping block 55 is movably clamped into the inside of the clamping slot 52;

[0029] The plug block 51 can be installed and connected, and the plug block 51 can be connected to the spring 54 through the installation groove 53. At the same time, the spring 54 can install and fix the clamping block 55, and can reset the clamping block 55 after being squeezed through its own elasticity. When the plug block 51 is inserted into the inside of the clamping groove 52, the installation block 4 can limit the connection block 3 through the connection between the plug block 51 and the clamping groove 52, and at the same time, after the clamping block 55 is clamped into the inside of the clamping groove 52, the plug block 51 and the connection block 3 can be limited and connected. At this time, the installation block 4 can smoothly increase the stability of the connection between the first bellows 1 and the second bellows 2 through the connection block 3;

[0030] When the insert block 51 is inserted into the slot 52, the block 55 will contact the connecting block 3, and through the thrust applied by the staff, the block 55 will move to one side of the spring 54, and squeeze the spring 54 while moving. When the insert block 51 is fully inserted into the slot 52, the block 55 can be reset by the elasticity of the spring 54, so that it can be smoothly connected to the inside of the connecting block 3, thereby realizing the limit connection between the first bellows 1 and the second bellows 2.

[0031] Preferably, the plug block 51 is located inside the mounting groove 53 and is fixedly connected to the limit rod 7. A through hole 8 is provided on one side of the block 55. The limit rod 7 is arranged inside the through hole 8. The block 55 is slidably connected to the outside of the limit rod 7. The plug block 51 can install and fix the limit rod 7 through the mounting groove 53. The opening of the through hole 8 allows the block 55 to slide smoothly on the outside of the limit rod 7. The block 55 can slide on the outside of the limit rod 7, so that when the block 55 moves to one side of the spring 54 due to the thrust applied by the staff, the movement of the block 55 can be sufficiently stable and is not prone to displacement or tilting. It can also limit the spring 54 to a certain extent, reducing the possibility of deformation and tilting of the spring 54 during extension and contraction.

[0032] Specifically, one side of the plug block 51 is fixedly connected to the limiting block 9, and a limiting groove 10 is provided inside the connecting block 3. The limiting groove 10 is communicated with the card slot 52, and the limiting block 9 is movably inserted into the limiting groove 10. The plug block 51 can be connected to the limiting block 9. When the plug block 51 is inserted into the card slot 52, the plug block 51 will smoothly drive the limiting block 9 to be inserted into the limiting groove 10, and the connecting block 3 can limit the plug block 51 through the connection between the limiting groove 10 and the limiting block 9, thereby increasing the stability of the plug block 51 when it is connected to the inside of the card slot 52, and reducing the possibility of shaking of the plug block 51 after use and insertion.

[0033] More specifically, the second bellows 2 is located inside the connecting groove 14 and is fixedly connected to the limiting plate 11, and the mounting block 4 is slidably connected to the outside of the limiting plate 11. The second bellows 2 can be installed and fixed to the limiting plate 11 through the connecting groove 14, and the limiting plate 11 can limit the mounting block 4, thereby increasing the stability and firmness of the mounting block 4 when it is connected to the inside of the connecting groove 14, thereby effectively reducing the possibility of the mounting block 4 falling off.

[0034] Furthermore, a sealing groove 13 is provided on one side of the first bellows 1, and a rubber block 12 is fixedly connected to one side of the second bellows 2. The rubber block 12 is movably inserted into the inside of the sealing groove 13, and the second bellows 2 can fix the rubber block 12. When the first bellows 1 and the second bellows 2 are connected together through the clamping mechanism 5, the connecting ring block 62 and the threaded ring block 63, the rubber block 12 can be smoothly inserted into the inside of the sealing groove 13, and the rubber block 12 can effectively improve the sealing performance of the first bellows 1 and the second bellows 2 after the connection, and reduce the possibility of leakage when the internal water source of the first bellows 1 and the second bellows 2 flows after the connection.

[0035] The implementation principle of a polyethylene corrugated pipe that is easy to splice in an embodiment of the present application is as follows: when in use, the staff can connect the first corrugated pipe 1 with the second corrugated pipe 2, and can rotate the first corrugated pipe 1 during the connection. The first corrugated pipe 1 will smoothly drive the connecting ring block 62 to rotate during the rotation, and smoothly connect the connecting ring block 62 to the inside of the threaded ring block 63 through a threaded connection, thereby realizing the connection between the first corrugated pipe 1 and the second corrugated pipe 2. It should be noted that when the first corrugated pipe 1 drives the connecting ring block 62 for rotational connection, the staff needs to hold the connecting block 3 so that the connecting block 3 does not rotate, and this allows the connecting block 3 to also smoothly move toward the installation when the first corrugated pipe 1 approaches the second corrugated pipe 2 through the threaded connection between the connecting ring block 62 and the threaded ring block 63. The block 4 moves to one side, and when the connecting block 3 moves to a certain distance, it will be connected to the outside of the plug block 51, and will contact with the card block 55 at the same time. Due to the subsequent movement of the connecting block 3, the connecting block 3 can squeeze the card block 55, so that the card block 55 can move smoothly to one side of the spring 54 and continue to squeeze the spring 54. After the first bellows 1 is connected with the second bellows 2, the plug block 51 can be smoothly inserted into the interior of the connecting block 3, and the card block 55 will also be reset by the elasticity of the spring 54, so as to be connected to the interior of the card slot 52, and the connection between the plug block 51 and the connecting block 3 can be completed. At this time, the connection between the first bellows 1 and the second bellows 2 can be completed, and at the same time, the stability and sealing of the connection between the first bellows 1 and the second bellows 2 can be increased.
