Embodiment 1

[0028] A connection structure of a single-wall corrugated pipe, including two single-wall corrugated pipes to be connected, the single-wall corrugated pipe includes a corrugated pipe body, one end of the pipe body is connected to a socket section 1, and the other end is connected to a The plug-in section 5, the ends of the socket section 1 and the plug-in section 5 are all open, and a sleeve 17 with openings at both ends is provided at the connection between the socket section 1 and the plug-in section 5, and the inner diameter of the sleeve 17 is provided with an inner Hollow installation ring 18, one side of installation ring 18 is provided with the first annular hole that cooperates with socket section 1, and the other side of installation ring 18 is provided with the second annular hole that cooperates with plug-in section 5; The end is provided with a first annular groove 12 extending horizontally to the inside of the socket section 1, and the radial direction of the socke...

Embodiment 2

[0032] Based on Embodiment 1, rubber rings 8 are provided on the outer walls of the socket section 1 and the insertion section 5 , and the outer diameter of the rubber ring 8 is larger than the inner diameter of the sleeve 17 . By setting the rubber ring 8, on the one hand, the sealed connection is ensured; on the other hand, the rubber ring 8 and the inner wall of the sleeve 17 generate frictional resistance, which increases the resistance to the rotation of the socket section 1 and the insertion section 5, and further improves the reliability of the connection.

Embodiment 3

[0034] Based on the above embodiment, the corrugation of the pipe body includes crests 9 and troughs 10, the crests 9 are hexagonal, and the corners are rounded.

Abstract

A connection structure of single-walled corrugated pipes includes two single-walled corrugated pipes needing to be connected. A single-walled corrugated pipe includes a pipe body, one end of the pipebody is connected with a socket section, and the other end is connected with a plugging section. A sleeve is arranged at the joint of the socket section and the plugging section. A hollow installationring is arranged in the radial direction in the sleeve. A first annular groove extending horizontally to the inside of the socket section is arranged in the end of the socket section. An installationhole communicated with the first annular groove is arranged in the radial direction in the socket section. A slider is arranged in the installation hole, and the slider is connected with the installation hole through a spring. A second annular groove matched with the slider is arranged in the outer wall of the plugging section. A first arc surface is arranged on the outer side of the slider, anda second arc surface matched with the first arc surface is arranged on the end of the plugging section. A through slot which extends from the open end of the plugging section to the second annular groove and can be matched with the slider is arranged on the outer wall of the plugging section. Under the action of external load, the plugging section and the socket section cannot be easily separated.The connection structure has the advantages of high reliability, good sealing performance and convenient disassembly.

Description

technical field [0001] The invention belongs to the technical field of single-wall corrugated pipe connectors, and in particular relates to a connection structure of single-wall corrugated pipes. Background technique [0002] PVC single-wall corrugated pipe is made of PVC as the main raw material through extrusion and blow molding. With soft features, it can be used as a casing for embedded wires. [0003] CN207049467 discloses a SFIP square single-wall corrugated pipe, which includes a pipe body. One end of the pipe body is provided with a socket, and the other end is provided with a rubber ring. The height of the rubber ring is greater than the height of the wave crest. In the socket, the rubber ring rubs against the inner wall of the socket to achieve the effect of connection and sealing. Although the patent realizes the connection through a simple structure, the application environment of the single-wall corrugated pipe used as a pre-embedded wire casing is usually har...
