Abstract

The utility model relates to pipe connection field and is designed for simplifying structure and making production easy, comprising a connector and an adapter, wherein the connector has a rotary head which is an intermediary cut through ball to insert into the adapter, and a leak-stopping sealing ring is lined on the contact sealing surface between the adapter and the rotary head, being characterized in that the rotary head and the connector is integral, and the port of the adapter oppresses inwardly positioning adjacent to the external surface of the rotary head to limit switch after the rotary head inserts into the port of the adapter. The utility model has the advantages of simple structure, easy manufacture and process, and low cost, and is applicable to spread and apply in gardening implement.

Description

Universal pipe joint

The utility model relates to the pipe joint technical field that connects sprinkler in the garden tool set.

Along with living standards of the people improve constantly, people are to more and more attention of living environment greening, in the greening process, especially in the inhabited residential district of richness, people often will use water pistol, water jetting apparatus and so on garden tool set and water flowers and trees, connect water pipe so also often will use pipe joint, and pipe joint commonly used is in the past generally only said to connect quickly and easily and taken over, and the universal rotation of energy, the universal pipe joint that can regulate water spraying direction easily is rare.There are scientific and technical personnel that pipe joint is carried out new technological improvement for this reason, it as the patent No. 95217898.2 Chinese patent " pipe joint ", it discloses a kind of pipe joint, it comprises the linking roofbolt of the joint afterbody that a hollow connects, cover rotary head thereon, leakage washer and accept head, an and nut, wherein rotary head is a ball, and has the hollow through hole, and leakage washer is the hollow ring, the front end of accepting head has can hold the circular arc spherical surface that connects the spheroidal rotary head, and the outer surface of this circular arc spherical surface is shaped on screw thread, and extends into two sections, and nut has an internal thread, its front-end face has the retaining edge than minor diameter, and this retaining edge inboard is a circular arc.This pipe joint can freely bend and rotate, thereby can change direction neatly.Also there are some defectives in it, and is simple inadequately as structure, and as needs roofbolt, rotary head, packing ring, accept head, nut etc., parts are a lot, so manufacture just more loaded down with trivial detailsly, cost of production can not reduce a lot, influences promoting the use of of its.It as the patent No. 97235177.9 Chinese patent " universal pipe joint ", it discloses a kind of universal pipe joint, comprise pipe, connection block, Sealing and bounding means, wherein, spheroid is fixed in tube end, sphere cavity is communicated with tube cavity, connection block has the shoulder hole inner chamber that can bury the body of receiving, Sealing is installed between shoulder hole ladder surface and the spheroid, and bounding means is connected between connection block and the spheroid partial sphere cambered surface, and this spheroid partial sphere cambered surface is positioned at the dorsal part of the spherical cambered surface that contacts with Sealing on the spheroid, but have implementation space third hand tap direction angle displacement, and the pipeline internal channel can keep advantage such as smooth and easy again.It also exists similar shortcoming, and structure is simple inadequately, and parts are also many as need pipe, connection block, Sealing, bounding means, and production and assembly are not easy, and cost can't reduce effectively.

The purpose of this utility model be to provide a kind of further improved, simple in structure, produce easily, universal pipe joint that cost is low.

The purpose of this utility model is achieved in that this kind universal pipe joint, it includes plug connector and supporting, have the rotary head that is inserted in the supporting on the plug connector, rotary head is the middle ball that connects, be lined with the leak-stopping seal ring between the contact seal face between supporting and the rotary head, it is characterized in that described rotary head and plug connector link into an integrated entity, and the port of the supporting outer surface that rotary head is pressed close in inside again compressing after rotary head is inserted carries out spacing.

Pipe joint of the present utility model, because the rotary head of plug connector with sphere linked into an integrated entity, and adopt the supporting port inwardly to oppress spacing structure is carried out in rotary head,, reduced parts so structure is simpler, need not bounding means, also need not independent roofbolt and nut, and simplified production technology, reduced some Metal fittings processing, reduced cost of production, helped it and on gardening, promote the use of.

Description of drawings.

The structure sectional view of the universal pipe joint that Fig. 1 is traditional;

Fig. 2 universal pipe joint structure of the present utility model sectional view;

Fig. 3 universal pipe joint external view of the present utility model.

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

Anticipate as shown in the figure, this universal pipe joint, it includes plug connector 1 and supporting 2, have the rotary head 3 that is inserted in the supporting 2 on the plug connector 1, rotary head 3 links into an integrated entity with plug connector 1, rotary head 3 is the middle ball that connects, so the flowing water passage of the flowing water passage of plug connector 1 and rotary head 3 is connected, the port of supporting 2 is pressed with special tool after rotary head is inserted, thereby the outer surface of inwardly oppressing rotary head 3 carries out spacing to rotary head 3, supporting 2 inner side surfaces have the ring groove 5 of lining leak-stopping seal ring 4, between the contact seal face between supporting 2 and the rotary head 3 leak-stopping seal ring 4 is arranged like this, make the rotary head 3 of universal pipe joint in supporting 2, rotate when regulating direction and can fully seal, can not leak, plug connector 1 is shaped on internal thread and the outside thread of taking over as water pipe for being connected with supporting 2 at jointing, takes over to connect easily.
