[0001] This utility model relates to the field of composite pipe technology, specifically a reinforced polyethylene composite pipe. Background Technology
[0002] With the acceleration of industrialization and urbanization, the demand for pipeline systems in energy transmission, municipal engineering, chemical industry and other fields has grown sharply; reinforced polyethylene composite pipe is a composite pipe that combines polyethylene base material and reinforcement structure, with excellent comprehensive performance and is widely used in various fields.
[0003] A search of Chinese patent CN215293988U reveals a polyethylene composite pipe comprising a pipe body, a connecting pipe at the left end of the pipe body, a connecting seat on the outer wall of the connecting pipe, and a sealing gasket on the left side wall of the connecting seat; a circular seat movably connected to the outer wall of the connecting pipe, with the connecting seat and the sealing gasket located inside the circular seat, and multiple protrusions on the outer wall of the circular seat; and a fixing seat located at the right end of the pipe body, with a screw matching the circular seat on the right side wall of the fixing seat. This device effectively facilitates the connection and use of polyethylene composite pipes, providing more stable fixation, better sealing, and preventing connector detachment. It also simplifies operation and increases the convenience and practicality of using polyethylene composite pipes, better meeting actual usage needs.
[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. In the maintenance of the pipe body, it is necessary to disassemble the pipe body. However, the pipe body in the existing technology is spliced together by nesting, which makes it difficult to disassemble the middle part of the pipe body. During the disassembly process, it is difficult to support the pipe body. As a result, when disassembling one end of the pipe body, the fixed part of the other end of the pipe body is damaged due to uneven force. In addition, it is difficult to protect the connection between the pipe bodies. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reinforced polyethylene composite pipe.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a reinforced polyethylene composite pipe, including a first pipe body and a second pipe body. Both the first pipe body and the second pipe body are provided with a snap-fit mechanism. The two sets of snap-fit mechanisms respectively include a support ring and a retaining ring fixedly installed on the first pipe body and the second pipe body. A support component is provided between the support ring and the retaining ring.
[0008] A connecting mechanism is provided between the support ring and the retaining ring. The connecting mechanism includes a conical ring fixedly installed on the retaining ring. A threaded sleeve is threadedly installed between the support ring, the retaining ring, and the conical ring.
[0009] A protective mechanism is provided between the conical ring and the threaded sleeve. The two sets of protective mechanisms each include a fixing component provided on the first tube body and the second tube body. The fixing component is provided with a shell. A sealing component is provided on both the first tube body and the second tube body.
[0010] Furthermore, the support assembly includes a plurality of first springs connected to the support ring, and each end of the plurality of first springs is connected to a locking block.
[0011] Furthermore, the retaining ring has multiple slots that are adapted to the retaining block.
[0012] Furthermore, each of the two sets of fixing components includes a fixing sleeve fixedly installed on the first tube and the second tube, respectively. The inner wall of the fixing sleeve is connected to a second spring, and the end of the second spring is connected to a telescopic rod that is slidably connected to the fixing sleeve.
[0013] Furthermore, a connecting frame that is fixed to the outer casing is fixedly installed at the end of the telescopic rod.
[0014] Furthermore, each of the two sets of sealing assemblies includes an annular plate fixedly installed on the first tube and the second tube, and an annular gasket that abuts against the outer shell is fixedly installed on the annular plate.
[0015] Furthermore, a circular block is rotatably mounted on the telescopic rod, and a support rod that is slidably connected to the fixed sleeve is fixedly mounted on the circular block. The support rod has a threaded groove that is threadedly connected to the fixed sleeve.
[0016] The above-described solution of this utility model has at least the following beneficial effects:
[0017] 1. In this utility model, by removing the threaded sleeve on the first pipe body from the retaining ring and conical ring on the second pipe body, the threaded sleeve no longer fixes the connection between the support ring and the retaining ring. By moving the first pipe body, the first pipe body moves the retaining block through the support ring. The retaining block on the first pipe body moves into the inner side of the support ring on the first pipe body under the pressure of the retaining groove on the second pipe body. This facilitates the disassembly of the first pipe body and the maintenance work, and will not cause damage to the first pipe body.
[0018] 2. In this utility model, by twisting the support rod on the first tube body, the support rod drives the round block to rotate, causing the threaded groove on the support ring to move away from the fixed sleeve. This allows the second spring to use its own elastic force to drive the outer shell on the first tube body to abut against the ring gasket on the second tube body through the telescopic rod and connecting frame. This facilitates the protection of the connection between the first tube body and the second tube body and further reinforces the connection. Attached Figure Description

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0027] like Figures 1 to 5As shown, an embodiment of this utility model provides a reinforced polyethylene composite pipe, including a first pipe body 1 and a second pipe body 2. Both the first pipe body 1 and the second pipe body 2 are provided with a snap-fit mechanism. The two sets of snap-fit mechanisms respectively include a support ring 3 and a snap ring 6 fixedly installed on the first pipe body 1 and the second pipe body 2. A support assembly is provided between the support ring 3 and the snap ring 6. The support assembly includes a plurality of first springs 4 connected to the support ring 3. The ends of the plurality of first springs 4 are all connected to snap blocks 5. The snap ring 6 is provided with a plurality of snap grooves 7 that are adapted to the snap blocks 5.
[0028] A connecting mechanism is provided between the support ring 3 and the retaining ring 6. The connecting mechanism includes a conical ring 8 fixedly installed on the retaining ring 6. A threaded sleeve 9 is threadedly installed between the support ring 3, the retaining ring 6 and the conical ring 8.
[0029] In this embodiment of the utility model, the worker removes the threaded sleeve 9 on the first tube 1 from the retaining ring 6 and the conical ring 8 on the second tube 2, so that the threaded sleeve 9 no longer fixes the connection between the support ring 3 and the retaining ring 6. By moving the first tube 1, the first tube 1 moves the retaining block 5 through the support ring 3. The retaining block 5 on the first tube 1 is squeezed into the inside of the support ring 3 on the second tube 2 by the retaining groove 7, which facilitates the disassembly of the first tube 1 and the maintenance work, and will not cause damage to the first tube 1.
[0030] When installing the first tube 1, the first tube 1 is moved between the second tube 2 and other tubes by a handling device. By squeezing, the first spring 4 can use its own elastic force to move the locking block 5 on the first tube 1 into the inner side of the locking groove 7 of the second tube 2, and move the threaded sleeve 9 on the first tube 1 onto the retaining ring 6 and the conical ring 8, thus completing the installation work.
[0031] Figures 1 to 5 As shown, a protective mechanism is provided between the conical ring 8 and the threaded sleeve 9. The two sets of protective mechanisms include fixing components provided on the first tube 1 and the second tube 2, respectively. The fixing components are provided with a housing 16. The first tube 1 and the second tube 2 are each provided with a sealing component. The two sets of fixing components include fixing sleeves 12 fixedly installed on the first tube 1 and the second tube 2. The inner wall of the fixing sleeve 12 is connected to a second spring 13. The end of the second spring 13 is connected to a telescopic rod 14 that is slidably connected to the fixing sleeve 12. The end of the telescopic rod 14 is fixedly installed with a connecting frame 15 that is fixed to the housing 16. The two sets of sealing components include ring plates 10 fixedly installed on the first tube 1 and the second tube 2, respectively. The ring plate 10 is fixedly installed with a ring gasket 11 that abuts against the housing 16. A round block 17 is rotatably installed on the telescopic rod 14. A support rod 18 that is slidably connected to the fixing sleeve 12 is fixedly installed on the round block 17. The support rod 18 is provided with a threaded groove 19 that is threadedly connected to the fixing sleeve 12.
[0032] In this embodiment of the utility model, the operator twists the support rod 18 on the first tube 1, causing the support rod 18 to drive the round block 17 to rotate, so that the threaded groove 19 on the support ring 3 moves away from the fixing sleeve 12, and the second spring 13 can use its own elastic force to drive the outer shell 16 on the first tube 1 to abut against the ring gasket 11 on the second tube 2 through the telescopic rod 14 and the connecting frame 15, thereby facilitating the protection of the connection between the first tube 1 and the second tube 2, and further reinforcing the connection.
[0033] Working principle: By removing the threaded sleeve 9 on the first pipe body 1 from the retaining ring 6 and conical ring 8 on the second pipe body 2, the threaded sleeve 9 no longer fixes the connection between the support ring 3 and the retaining ring 6. By moving the first pipe body 1, the first pipe body 1 moves the retaining block 5 through the support ring 3. The retaining block 5 on the first pipe body 1 is squeezed by the retaining groove 7 on the second pipe body 2 and moves into the inside of the support ring 3 on the first pipe body 1, so that the first pipe body 1 can be disassembled and then repaired.
[0034] After the maintenance is completed, the first pipe body 1 is moved to the second pipe body 2 between the other pipe bodies by the handling equipment. By squeezing, the first spring 4 can use its own elastic force to drive the locking block 5 on the first pipe body 1 to move into the inside of the locking groove 7 of the second pipe body 2. The threaded sleeve 9 on the first pipe body 1 is moved to the retaining ring 6 and the conical ring 8, and the installation work is completed.
[0035] The worker twists the support rod 18 on the first tube 1, causing the support rod 18 to drive the round block 17 to rotate, so that the threaded groove 19 on the support ring 3 moves away from the fixed sleeve 12, and the second spring 13 can use its own elastic force to drive the outer shell 16 on the first tube 1 to abut against the ring gasket 11 on the second tube 2 through the telescopic rod 14 and the connecting frame 15.
[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
