Description

Technical Field

[0001] This utility model relates to the field of drainage pipe anti-leakage technology, specifically a drainage pipe anti-leakage connection structure. Background Technology

[0002] In modern building and municipal engineering, the stable operation of drainage systems is of paramount importance. Drainage pipes, as a key component of the drainage system, are laid out underground or overhead according to design requirements. At the joints of the pipes, in order to ensure the continuity and sealing and prevent leakage during use, pipe joints are used to connect the two pipes. The reliability of the connection directly affects the performance of the entire drainage system.

[0003] A Chinese patent with publication number CN215763791U discloses a leak-proof structure for drainage pipe construction. The device uses a second sealing ring to compress the drainage pipe under the elastic force of two strong elastic pieces, so that the drainage pipe is tightly connected to the two sealing rings, thereby improving the sealing performance of the structure and preventing water leakage during use. The drainage pipe is limited and fixed in the connecting seat by the limiting engagement of the locking block and the locking hole, so as to prevent relative movement between the drainage pipe and the connecting seat during use and thus prevent the drainage pipe from loosening.

[0004] In the aforementioned literature, existing pipe connection structures can only be used to connect two pipes that are on the same straight line, and cannot be used to connect two pipes that are inclined. In addition, although there are corner joints in the existing technology, the joint angle is fixed and cannot be adjusted according to actual use needs, resulting in a limited scope of application. Therefore, a drainage pipe anti-leakage connection structure is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problem that existing technologies cannot connect two inclined pipes, thus limiting their applicability, this utility model proposes a leak-proof connection structure for drainage pipes.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The drainage pipe anti-leakage connection structure of this utility model includes two U-shaped pipes spliced ​​in opposite directions. The two U-shaped splices of the two U-shaped pipes are rotatably connected to the adapter pipes. The adapter pipes are fixedly connected to the installation pipes. The ends of the installation pipes are provided with adjustment components. The adjustment ends of the two adjustment components are respectively provided with connecting pipes.

[0007] The adjustment assembly includes an outer spherical shell fixed to the end of the mounting tube, an inner spherical shell slidably fitted inside the outer spherical shell, and a connecting tube fixed to the port on the side opposite to the mounting tube of the inner spherical shell.

[0008] The outer spherical shell has evenly distributed shrinkage grooves, and the inner wall of the outer spherical shell has a fixing groove. A rubber sealing shell is embedded and fixed in the fixing groove, and the rubber sealing shell is located on the outside of the inner spherical shell.

[0009] Both U-shaped tubes have their opposite sides cut off, and each of the cut-off points of the two U-shaped tubes is equipped with a telescopic component.

[0010] Preferably, two fastening bands are arranged oppositely on the outer side of the outer spherical shell, and ear plates are fixed to the splicing ends of the two fastening bands. A fastening bolt for fastening is provided through each pair of adjacent ear plates.

[0011] Preferably, the fastening band is provided with evenly distributed positioning plates on both sides, and the positioning plates are all fixed to the outer wall of the outer spherical shell. The positioning plates and the shrinkage groove are arranged in an alternating pattern.

[0012] Preferably, each of the adapter pipe ports is fixedly connected to a sleeve, and the end of the U-shaped tube is rotatably fitted into the sleeve. A sealing groove is provided on the inner wall of the sleeve. A first sealing ring is fixedly connected to each of the U-shaped tube ports, and the first sealing ring is rotatably fitted into the corresponding sealing groove.

[0013] Preferably, the telescopic component includes an inner tube coaxially disposed at the side cut-off point of the U-shaped tube, and the inner tube is simultaneously slidably disposed within the side cut-off port of the U-shaped tube.

[0014] Preferably, a first positioning ring is fixedly connected to the outer side of each of the two ports of the inner tube, and two second positioning rings are slidably disposed on the outer wall of the inner tube, with the two second positioning rings fixedly connected to the port at the cut-off point of the U-shaped tube.

[0015] Preferably, a second sealing ring is fixed to the side of each of the two second positioning rings, and the second sealing ring is located inside the port at the side cut of the U-shaped tube, and the second sealing ring is slidably sealed on the outside of the inner tube.

[0016] The advantages of this utility model are:

[0017] 1. This utility model allows the outer spherical shell to slide on the outside of the inner spherical shell during adjustment, causing the ports of the two U-shaped tubes to rotate within the adapter tube, thereby further increasing the angle adjustment range of another adjustment component and further improving the applicable range of the connection angle of the docking structure.

[0018] 2. By adjusting the extension length of the inner tube within the port at the side cut-off point of the U-shaped tube, the distance between the two adjusting components can be adjusted, thereby adjusting the connection distance between the two adjusting components to suit the docking of two ports with different distances, thus further improving the applicability of this pipe docking structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-6 As shown, a drainage pipe anti-leakage connection structure includes two U-shaped pipes 1 spliced ​​in opposite directions. A transition pipe 11 is rotatably connected to each of the two U-shaped splices of the two U-shaped pipes 1. An installation pipe 12 is fixedly connected to each of the transition pipes 11. An adjustment component 2 is provided at the end of each of the installation pipes 12. A connecting pipe 14 is provided at the adjustment end of each of the two adjustment components 2.

[0031] The adjustment assembly 2 includes an outer spherical shell 21 fixedly connected to the end of the mounting tube 12, an inner spherical shell 25 slidably fitted inside the outer spherical shell 21, and the connecting tube 14 fixedly connected to the port on the side opposite to the mounting tube 12 of the inner spherical shell 25.

[0032] The outer spherical shell 21 has evenly distributed shrinkage grooves 22, and the inner wall of the outer spherical shell 21 has a fixing groove 23. A rubber sealing shell 24 is embedded and fixed in the fixing groove 23, and the rubber sealing shell 24 is located outside the inner spherical shell 25.

[0033] Both U-shaped tubes 1 have their opposite sides cut off, and each of the cut-off points of the two U-shaped tubes 1 is provided with a telescopic component 3.

[0034] Two fastening bands 27 are arranged oppositely on the outer side of the outer spherical shell 21. The splicing ends of the two fastening bands 27 are fixed with ear plates 28. A fastening bolt 29 for fastening is provided through each pair of ear plates 28.

[0035] The fastening band 27 is provided with evenly distributed positioning plates 26 on both sides, and the positioning plates 26 are all fixed to the outer wall of the outer spherical shell 21. The positioning plates 26 and the shrinkage groove 22 are arranged in an alternating manner.

[0036] Each of the ports of the adapter pipe 11 is fixedly connected to a sleeve 13, and the end of the U-shaped pipe 1 is rotatably fitted into the sleeve 13. A sealing groove 15 is provided on the inner wall of the sleeve 13. A first sealing ring 16 is fixedly connected to each of the ports of the U-shaped pipe 1, and the first sealing ring 16 is rotatably fitted into the corresponding sealing groove 15.

[0037] The telescopic component 3 includes an inner tube 31 coaxially disposed at the side cut-off point of the U-shaped tube 1, and the inner tube 31 is simultaneously slidably disposed within the side cut-off port of the U-shaped tube 1.

[0038] A first positioning ring 32 is fixedly connected to the outer side of both ports of the inner tube 31. Two second positioning rings 33 are slidably arranged on the outer wall of the inner tube 31, and the two second positioning rings 33 are fixedly connected to the port at the cut-off point of the U-shaped tube 1.

[0039] Both of the two second positioning rings 33 are fixedly connected to the sides of the second sealing rings 34, and the second sealing rings 34 are respectively located inside the port at the side cut-off point of the U-shaped tube 1. The second sealing rings 34 are slidably sealed on the outside of the inner tube 31.

[0040] During operation, existing pipe connection structures can only connect two pipes that are in a straight line, and cannot connect two pipes that are inclined. Furthermore, although existing technologies include corner joints, the joint angle is fixed and cannot be adjusted according to actual usage requirements, thus limiting their applicability. In this solution, the orientation of the adjusting ends of two adjusting components 2 is adjusted according to individual needs. By connecting one end of a connecting pipe 14 to the pipe to be connected, and then adjusting the structure's posture, the end of the other connecting pipe 14 is aligned with the other pipe to be connected. At this point, the fixed connecting pipe... With the connection between the inner spherical shell 25 and the inner spherical shell 25 on the opposite side, the outer spherical shell 21 causes the rubber sealing shell 24 to slide on the outside of the inner spherical shell 25 during adjustment. After adjustment, the fastening band 27 is fastened to the outside of the outer spherical shell 21 by the fastening bolt 29. At this time, the outer spherical shell 21 deforms under the fastening and squeezing of the fastening band 27 to squeeze and seal the rubber sealing shell 24 on the outside of the inner spherical shell 25, and fixes the connection angle between the inner spherical shell 25 and the outer spherical shell 21. Similarly, the other adjusting component 2 can be adjusted and connected to another pipe that needs to be connected, so that pipes with different connection angles can be connected and used.

[0041] After one side adjustment component 2 is connected and fixed, the two U-shaped tubes 1 are rotated in the opposite direction according to the other pipe port, so that the ports of the two U-shaped tubes 1 rotate in the adapter pipe 11 respectively, so as to further improve the angle adjustment range of the other adjustment component 2, and thus further improve the application range of the connection angle of the docking structure.

[0042] By adjusting the extension length of the inner tube 31 within the port at the side cut-off point of the U-shaped tube 1, the distance between the two adjustment components 2 can be adjusted, thereby adjusting the connection distance between the two adjustment components 2 to suit the docking of two ports with different distances, thus further improving the applicability of this pipe docking structure.

[0043] This design achieves the function of connecting and preventing leakage in drainage pipes. Compared with traditional pipe connection structures, it can be used to connect pipes that are not on the same straight line, and the joint length can be adjusted according to the distance between the pipe ends, effectively improving the applicability of the pipe connection structure.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
