A quick-connection structure for PVC sewage pipes

Abstract

This utility model discloses a quick-connect structure for PVC sewage pipes, relating to the field of pipe connection technology. It solves the problems of inconvenience and low sealing performance of existing devices by adopting the following solution: a connection assembly is installed between pipe A and pipe B. This quick-connect structure for PVC sewage pipes, through the connection assembly and locking sleeve, allows pipes A and B to be inserted sequentially into connecting pipes A and B, respectively. Then, the locking sleeve provides locking and limiting. The structure is simple, reduces production costs, and improves ease of use. Simultaneously, the locking sleeve and rubber layer, along with the drainage direction, allow pipe A to be inserted into the inner wall of connecting pipe A, and connecting pipe B to be inserted into pipe B, preventing direct water flow. The rubber layer improves the sealing performance of the connection. Finally, the locking sleeve and locking bolt lock and limit the connection of pipes A and B, improving the contact of the connection and thus enhancing its sealing performance and effectiveness.

Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically a quick connection structure for PVC sewage pipes. Background Technology

[0002] Pipelines can be connected by threaded connections, flange connections, welding connections, socket connections, and pipe adhesive connections. However, connecting two pipe sections is currently cumbersome and inconvenient, requiring many tools, resulting in low installation efficiency and difficulty in disassembly. Furthermore, the sealing at the pipe connection is often poor, leading to leaks during use.

[0003] A search revealed that patent application CN118224418A discloses a connector structure for anti-clogging sewage pipes, including a first connector and a second connector. The outer diameter of the first connector is smaller than the inner diameter of the second connector. Multiple through holes are equidistantly arranged around the surface of the second connector, and a locking mechanism is provided on the outer surface of the through holes. Multiple locking blocks are equidistantly arranged around the outer surface of the first connector. When the first connector and the second connector are connected, the locking mechanism locks the locking blocks, thus fixing the first connector and the second connector together and improving the stability of the sewage pipe connection.

[0004] However, due to the threaded design, the sewage pipes are already laid on the ground during installation. The cut ends of the sewage pipes do not have threads, making it inconvenient to connect them using threaded connectors. This results in a complex structure, high production costs, and inconvenient use. Furthermore, the inconvenience of threaded connections leads to low sealing performance and a tendency for leaks.

[0005] Therefore, we propose a quick-connection structure for PVC sewage pipes. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-connect structure for PVC sewage pipes, which solves the problems of inconvenient use and low connection sealing of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-connect structure for PVC sewage pipes, comprising pipe A and pipe B;

[0008] A matching docking assembly is installed between pipe A and pipe B. The docking assembly consists of a docking pipe A, a fixed pipe and a docking pipe B from left to right. Two sets of matching locking sleeves are installed on the outer wall of the fixed pipe. The inner diameter of the docking pipe A is larger than the outer diameter of pipe A, and the outer diameter of the docking pipe B is smaller than the inner diameter of pipe B.

[0009] The top surface of the locking sleeve has an opening, and two sets of locking lugs in opposite positions are fixedly installed on the outer wall of the locking sleeve. Three sets of mounting holes in opposite positions are opened on the outer wall of the locking lugs. Locking bolts of the same specifications are fitted into the mounting holes. A rubber layer of the same specifications is fitted on the inner wall of the connecting pipe A, and a rubber layer of the same specifications is fitted on the outer wall of the connecting pipe B.

[0010] Preferably, a gasket A of the same specification is installed on the left side of the fixed pipe and inside the connecting pipe A, which can improve the sealing performance of the connection between the pipe A and the connecting pipe A.

[0011] Preferably, a gasket B of the same specification is fitted on the right side of the fixed pipe and outside the connecting pipe B, which can improve the sealing performance of the connection between the connecting pipe B and the pipe B.

[0012] Preferably, the connecting pipe, the fixing pipe, and the connecting pipe B are manufactured as a single unit, which can improve the overall sealing performance and service life of the docking assembly.

[0013] Preferably, a rubber sleeve of a matching specification is fixedly installed on the inner wall of the locking sleeve. This can improve the locking effect of the locking sleeve, prevent rotation, and also prevent the locking sleeve from damaging the pipeline.

[0014] Preferably, the specifications of the locking sleeve are adapted to the connecting pipe A and the pipe B respectively, so as to prevent the locking sleeve from being too large and affecting the locking effect.

[0015] 1. This quick-connect structure for PVC sewage pipes, through the setting of the connecting components and locking sleeve, first inserts pipe A and pipe B into the connecting pipe A and connecting pipe B in sequence, and then locks and limits them through the locking sleeve. The structure is simple, reduces production costs, and improves the convenience of use.

[0016] 2. Simultaneously, through the setting of locking sleeve and rubber layer, in the direction of drainage, pipe A is inserted into the inner wall of connector A, and connector B is inserted into pipe B. This can prevent water from flowing out directly. The rubber layer can improve the sealing of the connection. Then, the locking sleeve and locking bolt respectively lock and limit pipe A and pipe B, improve the contact of the connection, thereby improving its sealing and performance.
