Description

pipe connector

technical field

The utility model relates to a joint used for connecting plastic soft water pipes with faucets or water pipes.

Background technique

There are many kinds of existing water pipe joints, such as "a water pipe joint" disclosed in Chinese patent CN200520049933.6, and "a water pipe joint" disclosed in Chinese patent CN200620028311. More complex, inconvenient to operate, prone to leakage.

Utility model content

Aiming at the deficiencies in the prior art, the utility model aims to provide a water pipe joint with simple structure, easy operation and stable performance.

The technical scheme that the utility model adopts is:

A water pipe joint, which is composed of an inner joint and a tapered screw sleeve connected to each other through threads, the middle part of the inner joint is provided with a through water hole, the upper end is a threaded opening, the middle is a threaded section, and the lower end is a connecting water pipe The upper end of the tapered sleeve is a circular sleeve with internal threads, and there is a gap to accommodate the wall thickness of the water pipe between the tapered part of the lower end and the tapered sleeve of the inner joint.

A section of cylindrical body with diameter indented inward is provided between the threaded section of the inner joint and the tapered sleeve.

The tapered sleeve of the inner joint is provided with multiple annular ribs.

The rib surface is also tapered.

The connection method of the utility model is simple. When installing, the tapered sleeve of the inner joint is easily inserted into the plastic water pipe, and then the tapered screw sleeve of the outer ring of the joint is tightened by hand to lock it firmly. Watertight and airtight.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The reference signs are explained as follows:

11——Inner joint 12——Tapered screw sleeve

13——Water hole 14——Threaded port

15——Threaded section 16——Taper sleeve

17——cylindrical part 18——annular rib

19 - plastic water pipe

As shown in Figures 1 to 4, the water pipe joint is composed of an inner joint 11 and a conical screw sleeve 12 connected to each other through threads. The middle part of the inner joint 11 is provided with a through water hole 13, and the upper end is a threaded opening for connecting a faucet or a water pipe. 14. The middle part is a threaded part 15, and the lower end is a tapered sleeve 16 connected to the water pipe. There is a cylindrical part 17 with a diameter indented inwards between the threaded part 15 and the tapered sleeve 16. The tapered sleeve 16 is provided with multiple annular ribs 18, and the surface of the ribs 18 is also conical. The upper end of the conical screw sleeve 12 is a circular sleeve with internal threads, and the conical portion of the lower end is in contact with the conical portion of the inner joint. A gap to accommodate the wall thickness of the water pipe is left between the casing pipes 16 .

As shown in Figures 5 and 6, when installing, first pass the plastic water pipe 19 through the tapered screw sleeve 12, then insert the tapered sleeve 16 of the inner joint into the plastic water pipe 19, and then tighten the tapered screw sleeve 12 by hand , the plastic water pipe 19 is pressed on the tapered sleeve 16 by the tapered screw sleeve 12, the higher the position of the tapered screw sleeve 12, the smaller the gap between the tapered sleeve 16, and the plastic water pipe 19 is locked The tighter the firmer.

The utility model is not limited to the above-mentioned best implementation mode, and anyone can draw other various forms of products under the enlightenment of the present invention. But no matter any changes are made in its shape or structure, all technical solutions identical or similar to the utility model are all within its protection scope.
