Technical Field

The utility model relates to the technical field of pipeline connection, in particular to a pipeline connecting device for water supply and drainage engineering.

Background

The pipeline is a device for conveying gas, liquid or fluid with solid particles, which is formed by connecting pipes, pipe connectors, valves and the like, generally, the fluid flows from a high-pressure part to a low-pressure part of the pipeline after being pressurized by an air blower, a compressor, a pump, a boiler and the like, and can also be conveyed by utilizing the pressure or gravity of the fluid, the pipeline is widely used and mainly used in water supply, drainage, heat supply, gas supply, long-distance petroleum and natural gas conveying, agricultural irrigation, hydraulic engineering and various industrial devices, when temporary pipeline connection is carried out, pipeline connection needs to be carried out quickly, the reliability of pipeline connection needs to be ensured, the traditional flange connection type is not suitable, and therefore a pipeline quick connection structure is urgently needed to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of inconvenience and unreliability of the quick connection of the existing flange type pipeline, and provides a pipeline connecting device for water supply and drainage engineering.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a plumbing connection device for water supply and drainage engineering, includes the go-between, the inside bearing adapter sleeve of go-between, the inside inner splint that all is provided with in sheathed tube both sides, the tip outside of go-between is connected with two outer splint through the pivot, and the inside evenly distributed in both ends of go-between is provided with reset spring and connecting rod, and it has the cover to establish the catch outside outer splint through connecting rod bolt fastening.

Preferably, the outer part of the connecting ring is welded with a pull ring, and the outer part of the pull ring is sleeved with an anti-slip sleeve.

Preferably, both ends of the return spring respectively abut against the inner wall of the connection ring and the end of the connection rod.

Preferably, the end part of the outer clamping plate is welded with a clamping head, and the inner wall of the clamping head is provided with an anti-slip silica gel ring.

Preferably, the inner clamping plate is arranged in a conical shape.

Preferably, the surface of the outer clamping plate is provided with threads, and the inner wall of the locking ring is provided with thread grooves corresponding to the threads on the surface of the locking ring.

The utility model has the beneficial effects that:

embolia the interior splint outside respectively with two pipe water pipes, the interior splint surface and the water pipe inner wall in close contact with that utilize the toper to set up, and through the outer surface contact of pivot with outer splint and water pipe, the pulling pull ring this moment, it rotates at sheathed tube outside to drive the go-between, thereby the catch of pulling connecting rod tip rotates in the outside of outer splint, thereby the screwed outer splint is established on the thread groove extrusion surface of seting up through the inner wall, the realization utilizes interior splint and the swift water pipe of outer splint to fix, not only the installation is swift, and stability is good.
