Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a pipeline interface with an anti-slip structure. Background Art

[0002] The socket of existing PVC-O, PVC and other pipes has only one annular groove, in which a rubber sealing ring is installed. The rubber sealing ring is installed before the pipe is connected. This sealing type of socket has no restraint function on the connected pipe spigot end. If the pipe is not axially fixed, the interface will be easily detached due to the axial force generated by the internal water pressure. To solve this problem, a clamp is usually installed at the interface to increase the axial stability. However, the existing clamp structure generally needs to be fastened by multiple bolts, which is more troublesome to install. Utility Model Content

A sealing ring is provided in the annular sealing groove, and the sealing ring is fitted with the outer wall of the pipe socket.

[0008] Preferably, the threading hole is arranged tangentially to the annular channel.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] Under the restricting effect of the flexible clamping strip of the utility model, the socket inserted into the socket cannot be dislodged, thereby ensuring the tightness and stability of the axial connection between the two pipes. The flexible clamping strip is inserted through the hole on the outer wall of the socket, and the installation is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown, this embodiment discloses a pipe interface with an anti-drop structure, including a pipe socket 1, a pipe insert 2 and a flexible clamping strip 3, wherein the pipe socket 1 is plugged and matched with the pipe insert 2. The flexible clamping strip 3 is arranged between the pipe socket 1 and the pipe insert 2 to restrict the pipe insert 2 from falling out of the pipe socket 1.

[0018] An inner annular groove 101 is provided on the inner wall of the pipe socket 1, a threading hole 102 connected to the inner annular groove 101 is provided on the outer wall of the pipe socket 1, and an outer annular groove 201 is provided on the outer wall of the pipe socket 2. When the pipe socket 2 is plugged into the pipe socket 1, the inner annular groove 101 and the outer annular groove 201 are spliced ​​to each other to form an annular channel 4, and the flexible clip 3 is inserted into the annular channel 4 through the threading hole 102, and the flexible clip 3 is respectively embedded in the inner annular groove 101 and the outer annular groove 201. Under the restriction of the flexible clip 3, the pipe socket 2 inserted into the pipe socket 1 cannot be axially disengaged, which ensures the tightness and stability of the connection between the two pipes.

[0019] In this embodiment, the cross sections of the inner annular clamping groove 101 and the outer annular clamping groove 201 are both arc-shaped; the flexible clamping strip 3 can be specifically made of steel wire rope.

[0020] In this embodiment, the outer end of the flexible clamping strip 3 is located outside the threading hole 102, and a pull ring 301 is fixed to the outer end of the flexible clamping strip 3. The pull ring 301 facilitates the pulling of the flexible clamping strip 3.

[0021] In this embodiment, the threading hole 102 is arranged tangentially to the annular channel 4 , so that the flexible clip 3 can be easily inserted into the annular channel 4 through the threading hole 102 .

[0022] In this embodiment, an annular sealing groove 103 is formed on the inner wall of the pipe socket 1, and the annular sealing groove 103 is located inside the inner annular clamping groove 101. A sealing ring 5 is arranged in the annular sealing groove 103, and the sealing ring 5 is fitted with the outer wall of the pipe socket 2. The sealing ring 5 ensures the sealing performance of the plug-in fit between the pipe socket 1 and the pipe socket 2.
