Description

Technical Field

[0001] This utility model relates to the field of polyethylene pipe technology, specifically a polyethylene pipe. Background Technology

[0002] Currently, most polyethylene pipes in existing technologies are connected using heat fusion. However, this method is highly dependent on specialized equipment. In the absence of heat fusion equipment, connecting polyethylene pipes is often difficult, and the sealing performance after connection is hard to guarantee.

[0003] Therefore, there is an urgent need to develop a polyethylene pipe to solve the problems in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a polyethylene pipe that can achieve a sealed connection without relying on a heat fusion device, and has a simple structure and is easy to use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A polyethylene pipe, characterized in that it comprises: a pipe head, a pipe tail, and a connecting assembly; the pipe head and the pipe tail are fixedly connected by the connecting assembly, the pipe head has an extension layer inside, and the extension layer is fixedly connected to the pipe head; the connecting assembly comprises: a first connecting ring, a second connecting ring, a rotating ring, and an insert plate; the first connecting ring is disposed on the pipe head and fixedly connected to the pipe head, the second connecting ring is disposed on the pipe tail and fixedly connected to the pipe tail, the insert plate is disposed on the first connecting ring and fixedly connected to the first connecting ring, the rotating ring is disposed on the second connecting ring and rotatably connected to the second connecting ring; the insert plate and the rotating ring are threadedly connected to achieve the fixed connection between the pipe head and the pipe tail.

[0006] By adopting the above technical solution, when connecting polyethylene pipes, the insert plate is first inserted into the second connecting ring, and then the rotating ring is rotated to form a threaded engagement with the insert plate. This process causes relative displacement between the first and second connecting rings, thereby gradually pulling the pipe head and pipe tail closer together and tightly connecting them. As the rotating ring continues to screw in, the connection between the two becomes even tighter. The extension layer plays a crucial sealing role in this process, effectively preventing gas or liquid in the pipeline from leaking from the joint between the pipe head and pipe tail.

[0007] As a further embodiment of this utility model: a sealing groove is provided at the head end of the pipe, and a sealing ring is provided at the tail end of the pipe. The head end and the tail end of the pipe are sealed and fixedly connected by the sealing ring being embedded in the sealing groove.

[0008] By adopting the above technical solution, the sealing ring is added between the pipe head and the pipe tail, making it less likely for gas or liquid in the pipeline to leak from the gap between them.

[0009] As a further embodiment of this utility model: a slot is provided on the second connecting ring, and the insert plate is inserted into the slot to achieve a threaded connection with the rotating ring.

[0010] As a further aspect of this invention, the interior of the polyethylene pipe is provided with an antibacterial coating.

[0011] As a further embodiment of this utility model: a pressing groove is provided on the second connecting ring, the pressing groove communicating with the slot, and a fixing component is provided on the second connecting ring, the fixing component being used to fix the movement of the insert plate and the rotating ring.

[0012] By adopting the above technical solution, after the rotation of the rotating ring and the insert plate is completed, the fixing component is inserted into the pressing groove, so that the fixing component squeezes the insert plate and prevents the insert plate from retracting, which would cause the pipe connection to become loose.

[0013] As a further embodiment of this utility model: the fixing component includes a fixing rod and a pressing plate. The fixing rod is disposed on the second connecting ring and is fixedly connected to the second connecting ring. The pressing plate is disposed on the fixing rod and is slidably connected to the fixing rod. The pressing plate can be inserted into the pressing groove to fix the movement of the insert plate and the rotating ring.

[0014] By adopting the above technical solution, pressing the pressing plate will insert the pressing plate into the pressing groove and squeeze the insert plate to fix it and prevent it from retracting, which would cause the pipe connection to become loose.

[0015] Compared with the prior art, the advantages of this utility model are: it has significant advantages in simplifying the connection process, improving sealing performance and enhancing structural reliability, and is suitable for various industrial and civil pipeline connection scenarios.

[0016] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0021] By adopting the above technical solution, when connecting polyethylene pipes, the insert plate 35 is first inserted into the second connecting ring 32, and then the rotating ring 34 is rotated to form a threaded engagement with the insert plate 35. This process causes relative displacement between the first connecting ring 31 and the second connecting ring 32, thereby gradually pulling the pipe head 1 and the pipe tail 2 closer and tightly connecting them. As the rotating ring 34 continues to screw in, the connection between the two becomes even tighter. The extension layer 4 plays a crucial sealing role in this process, effectively preventing gas or liquid in the pipeline from leaking from the joint between the pipe head 1 and the pipe tail 2.

[0022] In this embodiment, a sealing groove 5 is provided at the end of the pipe head 1, and a sealing ring 6 is provided at the end of the pipe tail 2. The pipe head 1 and the pipe tail 2 are sealed and fixedly connected by the sealing ring 6 being embedded in the sealing groove 5.

[0027] By adopting the above technical solution, after the rotation of the rotating ring 34 and the insert plate 35 is completed, the fixing component 8 is inserted into the pressing groove 7, so that the fixing component 8 presses the insert plate 35, preventing the insert plate 35 from retracting and causing the pipe connection to become loose.

[0028] In this embodiment, the fixing component 8 includes a fixing rod 81 and a pressing plate 82. The fixing rod 81 is disposed on the second connecting ring 32 and is fixedly connected to the second connecting ring 32. The pressing plate 82 is disposed on the fixing rod 81 and is slidably connected to the fixing rod 81. The pressing plate 82 can be inserted into the pressing groove 7 to realize the movement of the fixing plate 35 and the rotating ring 34.

[0029] By adopting the above technical solution, the pressing plate 82 is pressed and inserted into the pressing groove 7 to squeeze the insert plate 35, thus fixing it and preventing it from retracting, which would cause the pipe connection to become loose.
