Description

Connector for low-pressure pipeline

Technical Field

The utility model provides a connector for a low-pressure pipeline, and belongs to the technical field of low-pressure pipeline connectors.

Background

The hydraulic pipeline is divided into a high-pressure pipeline and a low-pressure pipeline, wherein the high-pressure pipeline is used for passing liquid with pressure and needs to bear extremely high pressure; while the liquid in the low-pressure line is mostly pressureless. The connection between the hydraulic pipelines needs to use a pipe joint, wherein after the connection of the rubber pipe parts of the low-pressure pipelines is generally connected through the pipe joint, the pipe joint needs to be fixed by using a clamp, and the pipe joint is prevented from being separated from the low-pressure pipelines, however, the clamp needs to be contracted by using a screwdriver, so that the disassembly is also required by tools, and the disassembly is not convenient.

Disclosure of Invention

The connector for the low-pressure pipeline can solve the problem that the traditional low-pressure pipeline connector is inconvenient to disassemble.

In order to solve the problems, the technical scheme provided by the utility model is as follows: the connecting device comprises a connecting pipe and a low-pressure pipeline, connecting grooves matched with the inner walls of the low-pressure pipeline are respectively arranged on the outer sides of two ends of the connecting pipe, ribs are arranged on the outer sides of the connecting grooves, locking sleeves are respectively connected with the outer sides of two ends of the connecting pipe in a threaded mode, and conical grooves are formed in the locking sleeves.

Preferably, the low-pressure pipeline is in sliding connection with the connecting groove, and the low-pressure pipeline can be directly sleeved outside the connecting groove at two ends of the connecting pipe, so that the connection is convenient.

Preferably, the shape of the rib is annular, and the rib can increase the pressure between the low-pressure pipeline and the connecting groove, so that the low-pressure pipeline and the connecting groove are not easy to separate.

Preferably, the conical groove corresponds to the low-pressure pipeline, the structure of the conical groove can facilitate the locking sleeve to be sleeved outside the low-pressure pipeline, and the locking sleeve can extrude the low-pressure pipeline after being completely sleeved outside the low-pressure pipeline, so that the locking sleeve and the low-pressure pipeline are more tightly connected.

Preferably, one end of the locking sleeve is provided with a threaded hole communicated with the conical groove, and the outer side of the connecting pipe is provided with threads matched with the threaded hole.

Preferably, the thread is in threaded connection with the threaded hole.

The utility model has the beneficial effects that: when the low-pressure pipeline connecting pipe is detached, a tool is not required, the locking sleeve is rotated firstly to leave from the outer side of the low-pressure pipeline, and then the low-pressure pipeline can be pulled out of the outer side of the connecting pipe by force, so that the low-pressure pipeline connecting pipe is convenient to detach.
