Description

Technical Field

[0001] This utility model relates to the field of communication pipe technology, and in particular to a fracture-resistant polyethylene (PE) communication pipe. Background Technology

[0002] Polyethylene (PE) communication pipes are plastic pipes widely used in the laying of optical and electrical cables. Due to their excellent physical properties and ease of construction, they have become an important material for modern communication infrastructure. Fracture-resistant PE communication pipes are developed by blending and modifying traditional PE communication pipes to improve the pipe's ring stiffness, tensile strength, and impact resistance, thereby enhancing the pipe's fracture resistance.

[0003] During the construction and laying of fracture-resistant polyethylene (PE) communication pipes, it is often necessary to connect communication pipes together. For example, a multi-hole PE communication pipe structure disclosed in Chinese Patent [Publication No.: CN219779716U] involves inserting a fixing block of one PE communication pipe into the groove of another PE communication pipe. With just one insertion action, a locking mechanism automatically connects the two PE communication pipes. During disassembly, squeezing the locking block separates the two PE communication pipes, enabling quick connection, improving connection efficiency, and facilitating maintenance.

[0004] However, when the communication tube is removed, the structure requires axial movement of the communication tube to disengage the fixing block from the groove, which makes subsequent maintenance of the communication tube more troublesome, such as when some fixed or heavy communication tubes cannot be moved axially. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fracture-resistant polyethylene (PE) communication pipe, which solves the problem in the prior art that when the communication pipe is removed, it is necessary to move the communication pipe axially to make the fixing block detach from the groove, which makes the subsequent maintenance of the communication pipe more troublesome.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A fracture-resistant polyethylene (PE) communication pipe includes a polyethylene pipe body. One end of the polyethylene pipe body is provided with multiple mounting grooves, and the other end is provided with multiple locking grooves. A locking element is rotatably installed in the mounting groove. When two polyethylene pipe bodies are connected, the locking element locks into the locking groove of the connected polyethylene pipe body.

[0008] By setting up the above structure, when it is necessary to dismantle two interconnected polyethylene pipes, the locking piece can be unlocked from the locking groove and then unscrewed from the locking groove. There is no need to move the polyethylene pipes axially, which effectively reduces the maintenance difficulty for workers.

[0009] Furthermore, one end of the locking member is rotatably installed in the mounting groove, and a locking head is slidably provided at the end of the locking member away from the mounting groove. A limiting head is fixedly provided on the side of the locking member close to the locking groove. A locking hole and a limiting groove are provided in the locking groove. When the locking member is rotated into the mounting groove, the limiting head abuts against the end wall of the limiting groove, and the locking head is inserted into the locking hole.

[0010] By designing the above structure, during the process of the locking component being screwed into the mounting groove, the limiting head abuts against the end wall of the limiting groove, forcing the two polyethylene pipes to be connected closer together, ensuring the sealing of the connection between the two polyethylene pipes. After the locking component is screwed into the mounting groove, the locking head inserts into the locking hole to lock the position of the locking component, making the operation simple and quick.

[0011] Furthermore, the locking member has a mounting hole at the end away from the mounting groove, one end of the locking head is slidably disposed in the mounting hole, and a spring is disposed in the mounting hole, one end of the spring abutting against the end wall of the mounting hole, and the other end abutting against the end wall of the locking head.

[0012] By setting up the above structure, when the two polyethylene tubes are connected, the spring provides support for the locking head, so that the locking head is stably inserted into the locking hole and prevents the locking head from coming out of the locking hole.

[0013] Furthermore, the locking component has a sliding groove that communicates with the mounting hole, and a limit post is slidably disposed in the sliding groove, the limit post being fixedly connected to the locking head.

[0014] By setting the above structure, a sliding connection between the locking head and the locking element is achieved, and the position of the locking head can be changed by sliding the limiting post, making it easy to disengage the locking head from the locking hole.

[0015] Furthermore, a support rod is rotatably connected to the limiting post.

[0016] By setting up the above structure, the limiting post can be moved by pulling the support rod, further improving the convenience of moving and changing the position of the locking head. When the locking part is not screwed into the locking groove, the locking head can be completely located in the mounting hole by inserting the support rod into the sliding groove. After the locking part is screwed into the locking groove, the support rod is rotated and inserted into the sliding groove to lock the locking head in the locking hole.

[0017] Furthermore, an annular groove is provided at one end of the polyethylene pipe near the mounting groove, and a sealing ring is fixedly installed in the annular groove.

[0018] By setting up the above structure, the sealing performance of the connection between the two polyethylene pipes is further improved.

[0019] Furthermore, guide ramps are provided on both sides of the locking member.

[0020] By setting the above structure, it is easy for the locking element to be screwed into the locking groove.

[0021] The beneficial effects of this utility model are:

[0022] 1. By rotating the locking piece into the mounting groove, when it is necessary to remove the two interconnected polyethylene pipes, the locking piece is unlocked from the locking groove and then screwed out of the locking groove. There is no need to move the polyethylene pipes axially, which effectively reduces the maintenance difficulty for workers.

[0023] 2. By setting a locking head, a limiting head, a locking hole, and a limiting groove, during the process of the locking component being screwed into the mounting groove, the limiting head abuts against the end wall of the limiting groove, forcing the two polyethylene pipes to be connected closer together, ensuring the sealing of the connection between the two polyethylene pipes. After the locking component is screwed into the mounting groove, the locking head inserts into the locking hole to lock the position of the locking component. The operation is simple and quick.

[0024] 3. By setting a spring, when the two polyethylene tubes are connected, the spring provides support for the locking head, so that the locking head is stably inserted into the locking hole and prevents the locking head from coming out of the locking hole. Attached Figure Description

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0036] like Figures 1-3 As shown, this utility model discloses a fracture-resistant polyethylene (PE) communication pipe, comprising a polyethylene pipe body 1. One end of the polyethylene pipe body 1 has multiple mounting grooves 2, and the other end has multiple locking grooves 3. A locking element 4 is rotatably installed within the mounting grooves 2. When two polyethylene pipe bodies 1 are connected, the locking element 4 locks into the locking grooves 3 of the connected polyethylene pipe bodies 1. To disassemble the two connected polyethylene pipe bodies 1, the locking element 4 is unlocked from the locking grooves 3 and then unscrewed from the locking grooves 3. This eliminates the need for axial movement of the polyethylene pipe body 1, effectively reducing the maintenance difficulty for workers.

[0037] In this embodiment, the number of mounting slots 2 can be set to three or more, and six are preferred in this embodiment. The six mounting slots 2 are arranged at equal angles along the circumference of the polyethylene pipe body 1, and the number and position of the locking slots 3 correspond to the mounting slots 2.

[0038] In this embodiment, the locking member 4 is rotatably installed in the mounting groove 2 by a torsion spring, and the torsion spring causes the locking member 4 to have a tendency to rotate away from the polyethylene pipe body 1.

[0039] In this embodiment, one end of the locking member 4 is rotatably installed in the mounting groove 2, and a locking head 5 is slidably provided on the end of the locking member 4 away from the mounting groove 2. A limiting head 41 is fixedly provided on the side of the locking member 4 near the locking groove 3. The locking groove 3 has a locking hole 31 and a limiting groove 32. When the locking member 4 rotates into the mounting groove 2, the limiting head 41 abuts against the end wall of the limiting groove 32, and the locking head 5 is inserted into the locking hole 31. In some other embodiments, the locking member 4 can also use a conventional lock tongue and lock hole for locking. In this embodiment, by setting the locking head 5 and the limiting head 41, during the process of the locking member 4 rotating into the mounting groove 2, the limiting head 41 abuts against the end wall of the limiting groove 32, forcing the two polyethylene pipes 1 that need to be connected to move closer to each other, ensuring the sealing of the connection between the two polyethylene pipes 1. After the locking member 4 rotates into the mounting groove 2, the locking head 5 is inserted into the locking hole 31 to lock the position of the locking member 4. The operation is simple and quick.

[0040] In this embodiment, the locking member 4 has a mounting hole 42 at the end away from the mounting groove 2. One end of the locking head 5 is slidably disposed in the mounting hole 42. A spring 43 is disposed in the mounting hole 42, with one end of the spring 43 abutting against the end wall of the mounting hole 42 and the other end abutting against the end wall of the locking head 5. When the two polyethylene pipes 1 are connected, the spring 43 provides support for the locking head 5, so that the locking head 5 is stably inserted into the locking hole 31, preventing the locking head 5 from dislodging from the locking hole 31.

[0041] In this embodiment, the locking member 4 has a sliding groove 44, which communicates with the mounting hole 42. A limiting post 51 is slidably disposed in the sliding groove 44 and is fixedly connected to the locking head 5. This achieves a sliding connection between the locking head 5 and the locking member 4, and the position of the locking head 5 can be changed by sliding the limiting post 51, making it easy to disengage the locking head 5 from the locking hole 31.

[0042] In this embodiment, a support rod 52 is rotatably connected to the limiting post 51. By pulling the support rod 52, the limiting post 51 can be moved, further improving the convenience of moving and changing the position of the locking head 5. When the locking member 4 is not screwed into the locking groove 3, the support rod 52 can be inserted into the sliding groove 44, so that the support rod 52 is supported between the limiting post 51 and the end wall of the sliding groove 44, thereby making the locking head 5 completely located in the mounting hole 42. After the locking member 4 is screwed into the locking groove 3, the support rod 52 is rotated and inserted into the sliding groove 44, locking the locking head 5 in the locking hole 31.

[0043] In this embodiment, an annular groove 11 is provided at one end of the polyethylene pipe 1 near the mounting groove 2, and a sealing ring 12 is fixedly provided in the annular groove 11 to further improve the sealing performance of the connection between the two polyethylene pipes 1.

[0044] In this embodiment, guide slopes 45 are provided on both sides of the locking member 4 to facilitate the locking member 4 being screwed into the locking groove 3.

[0045] The method of using this utility model is as follows:

[0046] When two polyethylene pipes 1 are connected:

[0047] First, align the locking part 4 end of the polyethylene pipe 1 with the locking groove 3 end of the other polyethylene pipe 1.

[0048] Then, the locking member 4 is rotated into the locking groove 3 until the limiting head 41 abuts against the end wall of the limiting groove 32. During this process, the abutment between the limiting head 41 and the end wall of the limiting groove 32 forces the two polyethylene pipes 1 to move closer to each other and squeezes the sealing ring 12 in the annular groove 11.

[0049] Subsequently, the support rod 52 is unscrewed from the slide groove 44, and the spring 43 causes the locking head 5 to move towards the locking hole 31 until the locking head 5 is inserted into the locking hole 31. During the movement of the locking head 5, the support rod 52 moves synchronously through the limiting post 51. When the limiting post 51 moves to the end near the locking hole 31, the support rod 52 is screwed into the slide groove 44, locking the locking head 5 into the locking hole 31.

[0050] When disassembling the two polyethylene pipes 1:

[0051] First, unscrew the support rod 52 from the slide groove 44 and pull the support rod 52 away from the locking hole 31. During the movement of the support rod 52, the locking head 5 moves away from the locking hole 31 through the limiting post 51 until the locking head 5 disengages from the locking hole 31.

[0052] Then, rotate the locking member 4 out of the locking groove 3 so that the limiting head 41 is disengaged from the end wall of the limiting groove 32.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
