Description

Structure improved joint

Technical field

This utility model belongs to field of mechanical technique, particularly to a kind of structure improved connecing being applied to water pipe connection Head.

Background technology

When laying water pipe, due to the limited length of water pipe, need to realize two water by joint when connecting two water pipes The connection of pipe, and in actual life, often occur that the pipe diameter size needing two water pipes being connected differs, and due to joint The water receiving end internal diameter at two ends is shaped when producing, and is meeting in the case of two water pipe pipe diameter sizes differ, and original joint is The connection between two water pipes cannot be realized, accordingly, it would be desirable to design a can meet different tube diameters water pipe be connected joint.

Summary of the invention

The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of simple in construction, can fit Structure improved joint for various caliber water pipes.

The purpose of this utility model can be realized by following technical proposal: a kind of structure improved joint, including body, It is symmetrically arranged with two water service pipes, it is characterised in that two water service pipes are respectively connected with cross over pipe, in the outer end of water service pipe at body two ends Radially outward being formed with annular convex shoulder, be formed with two symmetrically arranged fixture blocks on annular convex shoulder, fixture block is by leading of being connected as a single entity Forming to portion and Access Division, guide part is connected with water service pipe outer face, and the width of Access Division is more than the width of guide part, cross over pipe Including the extension being connected as a single entity and connecting portion, the outer face of connecting portion offers cannelure and is provided with close in cannelure Seal, also has two symmetrically arranged draw-in grooves on the outer face of connecting portion and draw-in groove is positioned at ring slot outside, and fixture block is positioned at card Groove is interior and can circumferentially rotate, and the opening part at draw-in groove is formed with two symmetrically arranged catch, and the gap between two catch is more than leading To the gap between the width in portion, two catch less than the width of Access Division.

In above-mentioned structure improved joint, the internal diameter of extension is more than the internal diameter of connecting portion.

In above-mentioned structure improved joint, the internal diameter of extension is less than the internal diameter of connecting portion.

Compared with prior art, this utility model is by connecting cross over pipe on water service pipe, and the extension of cross over pipe is used for Being connected with water pipe, the connecting portion of cross over pipe is for being connected with water service pipe, owing to the caliber of water pipe is different, by differently configured connection Siphunculus, i.e. uses the extension of different tube diameters, so that this joint can be suitably used for the connection between various different tube diameters water pipe.

When needs cross over pipe is connected with body, first makes card block alignment draw-in groove and make fixture block be positioned at draw-in groove, then rotating Body so that fixture block moves in draw-in groove, owing to the gap between two catch is more than the width of guide part, therefore fixture block is passing through During catch, guide part can pass between two catch, and the gap between two catch is less than the width of Access Division, and this makes clamping Portion is stopped by catch and is limited in draw-in groove, so that body is fixedly connected with cross over pipe, by coordinating of fixture block and draw-in groove, Facilitate the handling between cross over pipe and body.

Detailed description of the invention

The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further Description, but this utility model is not limited to these embodiments.

As depicted in figs. 1 and 2, this structure improved joint includes body 1, is symmetrically arranged with two water flowings at body 1 two ends Pipe 11, two water service pipes 11 are respectively connected with cross over pipe 2, are radially outward formed with annular convex shoulder 111 in the outer end of water service pipe 11, at ring Being formed with two symmetrically arranged fixture blocks 112 on shape convex shoulder 111, fixture block 112 is by the guide part 1111 being connected as a single entity and Access Division 1112 compositions, guide part 1111 is connected with water service pipe 11 outer face, and the width of Access Division 1112 is more than the width of guide part 1111, Cross over pipe 2 includes extension 21 and the connecting portion 22 being connected as a single entity, the outer face of connecting portion 22 offers cannelure 222 and Sealing ring 3 is installed in cannelure 222, the outer face of connecting portion 22 also has two symmetrically arranged draw-in groove 221 and draw-in grooves 221 are positioned at outside cannelure 222, and the degree of depth of draw-in groove 221 is identical with the height of fixture block 112 and fixture block 112 is positioned at draw-in groove 221 also Can circumferentially rotate, the opening part at draw-in groove 221 is formed with two symmetrically arranged catch 223, and the gap between two catch 223 is more than The width of guide part 1111, the gap between two catch 223 is less than the width of Access Division 1112.

By connecting cross over pipe 2 on water service pipe 11, the extension 21 of cross over pipe 2 is used for being connected with water pipe, cross over pipe 2 Connecting portion 22, for being connected with water service pipe 11, owing to the caliber of water pipe is different, by differently configured cross over pipe 2, i.e. uses not With the extension 21 of caliber, so that this joint can be suitably used for the connection between various different tube diameters water pipe.

When needs cross over pipe 2 is connected with body 1, fixture block 112 is first made to be directed at draw-in groove 221 and make fixture block 112 be positioned at draw-in groove In 221, then rotate body 1 so that fixture block 112 moves in draw-in groove 221, owing to the gap between two catch 223 is more than leading To the width in portion 1111, therefore fixture block 112 is when through catch 223, and guide part 1111 can pass between two catch 223, and Gap between two catch 223 is less than the width of Access Division 1112, and this makes Access Division 1112 be stopped by catch 223 and limit In draw-in groove 221, so that body 1 is fixedly connected with cross over pipe 2, by coordinating of fixture block 112 and draw-in groove 221, facilitate UNICOM Handling between pipe 2 and body 1.

When body 1 connects and fixes rear with cross over pipe 2, the outer face crush seal circle 3 of water service pipe 11, so that water flowing Pipe 11 end and convex annular are along being in sealing contact, it is ensured that sealing when body 1 is connected with cross over pipe 2.

When needing the water pipe caliber connected less than water service pipe 11, select the internal diameter internal diameter less than connecting portion 22 of extension 21 Cross over pipe 2, when needing the water pipe caliber connected more than water service pipe 11, select interior more than connecting portion 22 of the internal diameter of extension 21 The cross over pipe 2 in footpath.

Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
