CN2231756Y - Joint ring - Google Patents

Abstract

The utility model relates to a joint ring, characterized in that the inner part of one end of the ring is provided with a notch and a circle of platform is formed. A sectional plane is approximately in an inverted convex shape. The outer part of the other end is provided with a circle of platform, a hole of an inner part is a platform cone, a sectional plane of the platform cone is in an inverse splayed shape and is communicated with a hole on the notch on one end of the ring. The utility model has the advantages of simple structure, low cost, and convenient connection, with no other tools needed. As long as a plastic pipe is inserted into the inverse splayed shape by a definite force. Experiments shows that a pulling force of 8 kg can also not cause the connected plastic pipes to fall off. The ring can be made into ten specifications and sizes, being suitable for pipe joints made by various engineering plastics.

Description

A kind of joint ring

The utility model relates to a kind of joint ring, and specifically a kind of joint for plastic tube that is used for comprises the joint ring of threeway, four-way.

At present people often adopt when connecting two sections plastic cement pipes and pinion one section hard tube with iron wire realize between two pipes, this method is not only time-consuming, effort and handle than hard mould pipe the time also be difficult to make its sealing water-tight, more be difficult to guarantee water-tight when pipe connects running into moulding of elbow or threeway, and existing pipe joint mostly is a fabricated metals, be connected and sealed by internal and external threads and pipeline, couple together very inconveniently, at present on market, also be difficult to find a kind of joint for plastic tube easy to connect simple in structure and the joint ring supporting with it.

It is a kind of simple in structure that the purpose of this utility model is to provide, and can be used for joint for plastic tube and comprise the joint ring that can be used for threeway, four-way, and it can make joint for plastic tube become very convenient when connecting plastic tube.

The technical solution of the utility model is achieved in that to be had a recess in an inside of joint ring and forms a circle platform, the approximate reversed convex type that is of section; There is a circle platform outside of other end, inner Kong Weiyi platform cone, and section is inverse and is connected with the hole at an interior notches place.

An available ultrasound of the present utility model and joint for plastic tube weld fixing, its interior notches contains pipe joint, the other end can connect moulds pipe, need only during connection by required size of moulding pipe, choose the pipe joint that this ring is housed accordingly, to mould pipe with certain power and get final product, not need any instrument from the mouth of falling Eight characters insertion.The utility model is simple in structure, and is easy to connect, and price is lower than 1 yuan, because the effect of the mouth of falling the Eight characters, with the pulling force of 8kg the pipe of moulding of connection come off through test, and this ring can be made the pipe joint that tens of kinds of specifications can be applicable to various engineering plastics manufacturings.

Fig. 1 is a generalized section of the present utility model.

The utility model will be further described below in conjunction with drawings and Examples.The utility model is a kind of joint ring that is used on the joint for plastic tube, and its end is except that the thickness that a circle ring wall is arranged, and inside is a recess 1, and forms a circle platform in inside, the approximate reversed convex type that is of section; There is a circle platform the other end outside of ring, inner hole 2 is that a platform cone section is inverse, and be connected with the hole of the indent of an end, the outside of whole ring is plane or the concave-convex curved surface that certain lonely degree is arranged, encircle the thickness of a circle berm width at an end interior notches 1 place greater than the joint for plastic tube tube wall that matches, make its inner recess 1 can contain plastic pipe union with ultrasonic welding fixedly the time with pipe joint, according to the required various different specifications of pipe of moulding, it is that section is down that the angle of the Eight characters is the 5-45 degree that the hole 2 of other end is cone, mould Guan Shixu with certain power in insertion, for preventing that pipe from inserting deeply other interface position that (as threeway or four-way) blocks joint, also can be provided with limit stoper on the main body section of joint.

Claims (2)

1. joint ring is characterized in that: there is a recess inside of ring and forms a circle platform, the approximate reversed convex type that is of section; There is a circle platform outside of other end, inner Kong Weiyi platform cone, and section is inverse and is connected with the hole at an interior notches place.

2. joint ring according to claim 1 is characterized in that: the outside of whole ring is plane or the concave-convex curved surface that certain lonely degree is arranged; The one circle berm width at an interior notches place of ring is greater than the thickness of moulding tube wall that matches; The other end section is for falling the Eight characters, and the angle that the hole is cone is the 5-45 degree.
