Description

Technical Field

[0001] This utility model belongs to the technical field of PE spiral wound structured wall pipes, specifically relating to a reinforced PE spiral wound structured wall type B pipe. Background Technology

[0002] PE spiral wound structure wall pipes are a general term for thermoplastic round pipes made primarily of polyethylene resin using a spiral winding process, designed for use without internal pressure. Among them, Type B pipes are characterized by excellent material, unique structure, superior performance, simple connection, convenient construction, environmental protection and energy saving, and wide applicability. They are suitable for various municipal engineering projects and drainage needs, such as urban rainwater drainage, sewage discharge, and farmland irrigation.

[0003] Currently, most B-type PE spiral wound structural wall pipes on the market are connected using flanges and threads. Among these, threaded B-type pipes generally have a smaller diameter. To ensure a tight seal at the joint between the two pipes, PTFE tape needs to be wrapped around the external threads.

[0004] Threaded connections have the advantages of simple structure and convenient operation. However, when B-type pipes are connected by threaded structure, they also have the following disadvantages: First, in order to ensure the sealing of the pipe joint, it is necessary to pre-wrap PTFE tape. This method not only affects the efficiency of pipe connection, but also the sealing quality is affected by the quality of PTFE tape wrapping. In addition, when the pipe is not stably fixed and clamped during use, the threaded structure between the two pipes may loosen due to pipe vibration, resulting in a reduction in the sealing of the pipe joint. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a reinforced PE wound structure wall type B pipe, which solves the problem that the sealing performance of existing PE wound structure wall type B pipes is affected by the quality of the PTFE tape winding and pipe vibration when connected by bolts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced PE spiral wound structure wall type B pipe, comprising a PE spiral wound structure wall pipe, wherein both ends of the PE spiral wound structure wall pipe are respectively provided with a plug-in interface and a socket interface, wherein a first diameter reducing section is formed in the plug-in interface, and an external thread for threaded connection of an internally threaded pipe is formed on the outer side of the first diameter reducing section, wherein multiple annular snap-fit ​​teeth are formed on the outer side surface of the plug-in interface between the external thread and the plug-in interface port, and a sealing ring is installed at the end of the plug-in interface; a second diameter reducing section is formed on the socket interface, and an internally threaded pipe is rotatably snapped between the second diameter reducing section and the port of the socket interface; wherein an elastic snap-fit ​​plate is inclined away from the plug-in interface on the inner wall of the socket interface, and the end of the elastic snap-fit ​​plate is adapted to snap-fit ​​annular snap-fit ​​teeth.

[0007] The beneficial effects of this utility model are as follows: two PE spiral wound structural wall pipes are connected through a plug interface and a socket interface. The threaded mechanism causes the plug interface and the socket interface to push against each other, so that the elastic snap-fit ​​plate is snapped into the groove of the annular snap-fit ​​tooth. The plug interface and the socket interface are firmly connected by the elastic snap-fit ​​method, and the sealing ring is used to ensure the sealing of the connection between the two PE spiral wound structural wall pipes.

[0008] To ensure a stable connection between the connector and the socket;

[0009] As a further improvement to the above technical solution: the number of elastic snap-fit ​​plates is multiple, and they are equidistantly spaced around the axis of the receiving interface.

[0010] The beneficial effects of this improvement are: multiple equidistant elastic snap-fit ​​plates can ensure the uniformity of force on the connection between the plug and the socket, thereby ensuring the stability of the connection between the plug and the socket.

[0011] In order to achieve a stable unidirectional engagement between the flexible snap-fit ​​plate and the ring snap-fit ​​teeth;

[0012] As a further improvement to the above technical solution: the annular snap-fit ​​tooth is an annular tooth with a right-angled triangular cross-section, and the bottom surface of the annular snap-fit ​​tooth faces away from the end of the insertion interface.

[0013] The beneficial effects of this improvement are as follows: during the process of inserting the ring-shaped snap-fit ​​tooth into the socket, the inclined surface slides and connects with the elastic snap-fit ​​plate, and pushes the elastic snap-fit ​​plate to produce elastic deformation. The elastic snap-fit ​​plate is snapped into the tooth groove formed between the adjacent ring-shaped snap-fit ​​teeth to achieve unidirectional snap-fit ​​of the ring-shaped snap-fit ​​tooth.

[0014] To facilitate effortless insertion of the socket and receptacle by using an internally threaded tube;

[0015] As a further improvement to the above technical solution: the end of the receiving interface is bent outward to form an end plate adapted to snap onto the internally threaded pipe.

[0016] The beneficial effects of this improvement are: the internally threaded pipe can be installed on the socket, which in turn drives the socket to move stably towards the insertion port.

[0017] To effectively ensure the sealing of the connection between the plug and socket;

[0018] As a further improvement to the above technical solution: the outer surface of the sealing ring has the same slope as the inner wall of the variable diameter section two.

[0019] The beneficial effect of this improvement is that the outer surface of the sealing ring can be pressed against the inner wall of the second diameter section to achieve a seal at the connection between the insertion and receiving interfaces.

[0020] To ensure a stable connection between the internally threaded tube and the insertion interface;

[0021] As a further improvement to the above technical solution: the first diameter-changing section is a pipe structure that is thicker in the middle and thinner at both ends, and the external thread is set in the middle part of the first diameter-changing section.

[0022] The beneficial effect of this improvement is that the internally threaded pipe can be smoothly connected to the externally threaded section formed at the thickest part of the reducing section.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] Example 1:

[0031] like Figure 1As shown in Figure 4: A reinforced PE spiral wound structural wall type B pipe includes a PE spiral wound structural wall pipe 100. The PE spiral wound structural wall pipe 100 has a plug-in interface 1 and a socket interface 2 at both ends. A reducing section 4 is formed in the plug-in interface 1. An external thread 5 for threaded connection to an internally threaded pipe 3 is formed on the outer side of the reducing section 4. Multiple annular locking teeth 6 are formed on the outer surface of the plug-in interface 1 between the external thread 5 and the port of the plug-in interface 1. A sealing ring 7 is installed at the end of the plug-in interface 1. A reducing section 8 is formed on the socket interface 2. An internal thread is rotatably engaged between the reducing section 8 and the port of the socket interface 2. The inner wall of the socket 2 is inclined away from the insertion port 1 and connected with an elastic snap-fit ​​plate 9. The end of the elastic snap-fit ​​plate 9 is adapted to snap-fit ​​annular snap-fit ​​teeth 6. The two PE wound structure wall pipes 100 are connected through the insertion port 1 and the socket 2. The threaded mechanism causes the insertion port 1 and the socket 2 to push against each other, so that the elastic snap-fit ​​plate 9 is snapped into the groove of the annular snap-fit ​​teeth 6. The connection between the insertion port 1 and the socket 2 is completed by elastic snap-fit, and the sealing ring 7 ensures the sealing of the connection between the two PE wound structure wall pipes 100. There are multiple elastic snap-fit ​​plates 9, which surround the socket 2. The equidistantly spaced elastic locking plates 9 ensure uniform force distribution between the insertion interface 1 and the receiving interface 2, thereby guaranteeing the stability of the connection. The annular locking teeth 6 are right-angled triangular ring teeth with their bottom surfaces facing away from the end of the insertion interface 1. During the insertion of the insertion interface 1 into the receiving interface 2, the inclined surfaces of the annular locking teeth 6 slide against the elastic locking plates 9, causing elastic deformation. The elastic locking plates 9 engage with the grooves formed between adjacent annular locking teeth 6, achieving unidirectional engagement. The end of port 2 is bent outward to form an end plate that fits and snaps onto the internally threaded tube 3. The internally threaded tube 3 can be limited and installed on the socket 2, driving the socket 2 to move stably towards the insertion port 1. The outer side of the sealing ring 7 has the same slope as the inner wall of the variable diameter section 8. The outer side of the sealing ring 7 can fit and press against the inner wall of the variable diameter section 8 to achieve a seal at the connection between the insertion port 1 and the socket 2. The variable diameter section 4 is a variable diameter tube structure that is thick in the middle and thin at both ends. The external thread 5 is set in the middle part of the variable diameter section 4. The internally threaded tube 3 can be smoothly threadedly connected to the external thread 5 formed in the thickest part of the variable diameter section 4.

[0032] The working principle of this technical solution is as follows: the insertion port 1 of one PE wound structural wall pipe 100 is inserted into the receiving port 2 of another PE wound structural wall pipe 100, and the internal threaded pipe 3 is rotated to make the internal threaded pipe 3 threadedly connected to the external thread 5. As the internal threaded pipe 3 rotates, the insertion port 1 is gradually inserted into the interior of the receiving port 2. The annular snap-fit ​​teeth 6 push the elastic snap-fit ​​plate 9 to repeatedly generate elastic deformation until the sealing ring 7 is pressed tightly against the inner wall of the variable diameter section 8. At this time, the end of the elastic snap-fit ​​plate 9 abuts against the groove formed between two adjacent annular snap-fit ​​teeth 6, thus completing the stable connection and sealing between the insertion port 1 and the receiving port 2.
