Description

Technical Field

[0001] This utility model relates to building pipeline technology, and in particular to a connection structure for polyvinyl chloride drainage pipes. Background Technology

[0002] In the construction industry, PVC drainage pipes are mainly used in bathrooms, kitchens, balconies, and other locations where they penetrate floors and require waterproofing. Traditional drainage pipes are connected by adhesive, but this adhesive connection method has the following disadvantages: 1. The surface of the PVC pipe needs to be ground and coated with adhesive, which takes a long time to complete.

[0003] 2. Under prolonged water flow impact or gravity, gaps may form between drain pipes, leading to leakage problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide a PVC drainage pipe connection structure that makes the connection firm and reliable, and greatly reduces the risk of leakage caused by the detachment of the water-stop joint.

[0005] This utility model provides a polyvinyl chloride drainage pipe connection structure, including a drainage pipe inlet and a drainage pipe socket, wherein the drainage pipe inlet and the drainage pipe socket are connected by a limiting structure.

[0006] In the above technical solution, the limiting structure is a male-female joint structure formed by the female joint located at the drain pipe socket and the female joint located at the drain pipe inlet.

[0007] In the above technical solution, the end of the sub-port facing away from the drain pipe socket is provided with a first limiting surface ring, and the side wall of the sub-port is provided with a conical surface ring.

[0008] In the above technical solution, a first stop ring is provided at the end of the sub-port that is close to the drain pipe socket.

[0009] In the above technical solution, the female port is in the form of a convex ring structure, and an annular cavity is provided inside the convex ring structure, and the female port is located inside the annular cavity.

[0010] In the above technical solution, the end face of the inner wall of the annular cavity away from the drain pipe inlet is provided with a second stop ring that abuts against the first stop ring.

[0011] In the above technical solution, the end face of the inner wall of the annular cavity near the drain pipe inlet is provided with a second limiting surface ring that abuts against the first limiting surface ring.

[0012] In the above technical solution, the side wall of the sub-port is provided with a cylindrical ring parallel to the side wall of the drain pipe, wherein the cylindrical ring is connected to the first limiting surface ring, and the conical ring is connected to the first stop ring.

[0013] In the above technical solution, the inner wall of the annular cavity abuts against the cylindrical ring.

[0014] The polyvinyl chloride drainage pipe connection structure of this utility model has the following beneficial effects: This type of drainage pipe uses a male-female joint connection, eliminating the need for adhesives and avoiding steps such as grinding, applying glue, and curing. This saves construction time while increasing stability and eliminating the risk of water leakage caused by the drainage pipe becoming disconnected. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0017] Reference Figures 1 to 3 As shown, the present invention provides a PVC drain pipe connection structure, including a drain pipe inlet 1 and a drain pipe socket 2, wherein the drain pipe inlet 1 and the drain pipe socket 2 are connected by a limiting structure.

[0018] The limiting structure is a male-female joint structure formed by the female joint 1-1 located at the drain pipe inlet 1 and the female joint 2-1 located at the drain pipe socket 2.

[0019] The end of the sub-port 1-1 facing away from the drain pipe socket 2 is provided with a first limiting surface ring, and the side wall of the sub-port 1-1 is provided with a conical surface ring.

[0020] The end of the sub-port 1-1 that is close to the drain pipe socket 2 is provided with a first stop ring.

[0021] The female port 2-1 has a convex ring structure, and the convex ring structure has an annular cavity. The female port 1-1 is located in the annular cavity.

[0022] The inner wall of the annular cavity is provided with a second stop ring that abuts against the first stop ring at the end face away from the drain pipe inlet 1.

[0023] The inner wall of the annular cavity is provided with a second limiting surface ring that abuts against the first limiting surface ring at the end face near the drain pipe inlet 1.

[0024] The sidewall of the sub-port 1-1 is provided with a cylindrical ring parallel to the sidewall of the drain pipe, wherein the cylindrical ring is connected to the first limiting surface ring, and the conical ring is connected to the first stop ring. The inner sidewall of the annular cavity abuts against the cylindrical ring.

[0025] In this invention, the drain pipe socket end 2 is connected to the drain pipe insertion end 1, so that the male end 1-1 and the female end 2-1 are locked and fixed. This is more secure and reliable than traditional bonding, eliminating the risk of leakage caused by drain pipe disconnection.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
