Abstract

A plastic pipe connecting device. A rubber sealing ring is arranged between the lower end of the plastic pipe connecting pipe and the plastic pipe joint, a positioning ring is arranged between the upper end of the plastic pipe connecting pipe and the plastic pipe joint, the rubber sealing ring is arranged between the lower end of the plastic pipe connecting pipe perpendicular to the plastic pipe joint and the plastic pipe joint, a pressing ring is arranged between the positioning ring parallel to the plastic pipe joint and the thread fixing ring, and a limiting ring is arranged on the periphery of the thread fixing ring. Compared with the prior art, the plastic pipe connecting device overcomes the defects in connection, can effectively prevent the water pipe from sliding, and the rubber fixing ring can ensure the sealing of the connection part, thereby effectively ensuring the connection quality of the plastic pipe, reducing the connection cost and realizing the firm connection between the plastic pipes.

Description

Plastic pipe connecting device
Technical Field
The utility model relates to a plastic tubing connecting device relates to that the plastic tubing is connected technical field, is applied to the plastic tubing and connects.
Background
At present, when plastic pipes with larger calibers are connected, the pressure per unit area is large, the plastic pipes are easily degummed in the long-term use process in a glue bonding mode, water leakage is caused, the two plastic pipes are connected by clamping rubber sealing rings through the two fixing rings, the connecting device not only increases the connecting difficulty and has high cost, but also causes the water leakage of the joint due to the dislocation or looseness caused by the long-time water flow vibration, and therefore unnecessary loss is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned defect, improve prior art, design a new connecting device, realize the connection and the sealing of plastic tubing, effectively lock when effectively guaranteeing the plastic tubing connection to guarantee a plastic tubing connecting device of sealed quality.
The technology is realized as follows: including rubber seal, thread tightening ring, clamping ring, spacing collar, plastic tubing coupling, plastic tubing takeover, position ring, its characterized in that: a rubber sealing ring is arranged between the lower end of the plastic pipe connecting pipe and the plastic pipe joint, a positioning ring is arranged between the upper end of the plastic pipe connecting pipe and the plastic pipe joint, the rubber sealing ring is arranged between the lower end of the plastic pipe connecting pipe perpendicular to the plastic pipe joint and the plastic pipe joint, a pressing ring is arranged between the positioning ring parallel to the plastic pipe joint and the thread fixing ring, a limiting ring is arranged on the periphery of the thread fixing ring,
the outer diameter opening of the plastic pipe joint is provided with threads which are matched with the threads of the thread fixing ring,
the periphery of the positioning ring is provided with a taper.
The obvious advantages and effects after the technology is implemented are as follows: compared with the prior art, the plastic pipe connecting device overcomes the defects in connection, can effectively prevent the water pipe from sliding, and the rubber fixing ring can ensure the sealing of the connection part, thereby effectively ensuring the connection quality of the plastic pipe, reducing the connection cost and realizing the firm connection between the plastic pipes.
Drawings
FIG. 1 is a schematic view of the front view structure of the present invention,
wherein, 1-rubber sealing ring, 2-thread fixing ring, 3-pressing ring, 4-spacing ring, 5-plastic pipe joint, 6-plastic pipe connecting pipe, and 7-positioning ring.
Detailed Description
The present invention will be further described with reference to the following drawings, taking a three-way connection as an example:
referring to the attached figure 1, a rubber sealing ring 1 is arranged between the lower end of a plastic pipe connecting pipe 6 and a plastic pipe joint 5, a positioning ring 7 is arranged between the upper end of the plastic pipe connecting pipe 6 and the plastic pipe joint 5, the rubber sealing ring 1 is arranged between the lower end of the plastic pipe connecting pipe 6 perpendicular to the plastic pipe joint 5 and the plastic pipe joint 5, a pressing ring 3 is arranged between the positioning ring 7 parallel to the plastic pipe joint 5 and a thread fixing ring 2, a limiting ring 4 is arranged on the periphery of the thread fixing ring 2,
the outer diameter opening of the plastic pipe joint 5 is provided with threads matched with the threads of the thread fixing ring 2,
the periphery of the positioning ring is provided with a taper.
The entire coupling device acts on the plastic pipe joint 5, see fig. 1. Be equipped with the screw thread on the external diameter mouth of plastic pipe joint 5, 6 peripheries of plastic pipe joint are sheathe in successively rubber seal 1 and position ring 7 and are inserted in the downthehole of plastic pipe joint 5, position ring 7 parallel with plastic pipe joint 5, put into clamping ring 3 between the thread tightening ring 2, thread tightening ring 2 compresses tightly clamping ring 3 on plastic pipe joint 5 through the screw thread soon, the clamping ring 7 locking thread tightening ring 2 in the 2 outsides of thread tightening ring, the clamping ring 3 and the position ring 7 of design can prevent effectively that the water pipe from removing, the sealed of junction is guaranteed to rubber seal 1.
