Description

A kind of New type water pipe joint

Technical field

It the utility model is related to a kind of novel pipe fitting fastening means, and in particular to a kind of water pipe head.

Background technology

Many aspects in daily life will use water, sometimes need some water pipe heads to be used cooperatively, The damage of anti-antipriming pipe, most water pipe head is all integrally formed on the market now, and this water pipe head is typically all Made of copper, sealing property is strong, but processed complex, and price is very high, once being broken, that whole water pipe head all will report It is useless, take very much material, what we to be done now is exactly in the case where not destroying sealing, is that water pipe head is fabricated to reduction.

The content of the invention

In view of the shortcomings of the prior art, the utility model provides one kind and does not destroy sealing in the case of not waste of materials The New type water pipe joint of property.

What the purpose of this utility model was realized in：

A kind of New type water pipe joint, including housing, the housing include adapter sleeve and connecting tube, the connecting tube one into Type has inner housing and pipe fitting junction, and the left end inwall of the adapter sleeve offers rounded corner C, the right-hand member face ring of the adapter sleeve Shape offers a stair-stepping groove, and the both ends of the inner housing are connected on rounded corner C and stair-stepping groove respectively.

Preferably, one end annular shaped on the inwall of the adapter sleeve has step in one, and the external diameter of the inner housing supports It is connected on the interior step of the adapter sleeve.

Preferably, the intersection of the inner housing and pipe junction forms the projection of an annular, the raised and pipe fitting A rounded corner B is offered on the intersection of junction, the projection is connected on stair-stepping groove.

Preferably, the end face of the low order end of the connecting tube forms rounded corner A.

Preferably, the screw thread being spirally connected with pipe fitting is provided with the adapter sleeve.

Preferably, the material that the connecting tube is selected is aluminium.

Preferably, the material that the adapter sleeve is selected is copper.

The utility model is prominent and beneficial compared with prior art to be had the technical effect that：

1. joint core of the present utility model be stamping connection on public tooth, that segment length of inner housing is more than in joint core The axial length of public tooth, the external diameter of inner housing is slightly less than the internal diameter of public tooth, after the completion of punching press, length meeting that section of inner housing has more The sealing during edge of public tooth is connected directly between, better tightness can be made.

2. the utility model uses Sheet Metal Forming Technology, sealing can be attached with most of adapter sleeve, is set on adapter sleeve There is screw thread, be conveniently fixed in connecting tube and conveniently dismantle, and will not damage easily.

3. adapter sleeve inner annular of the present utility model forms one section of raised ladder, the external diameter of inner housing is connected to this On section ladder, make to form one section of air layer between adapter sleeve and inner housing, realize triple seal, liquid is not let out from inside Leakage.

4. the material selected by the utility model connecting tube is aluminium 6061, this material processing characteristics is splendid, has good Corrosion resistance, toughness is high, indeformable after processing, and the material that adapter sleeve is selected is copper H62, and this material price is cheap, and plasticity is good, Machinability is good, and corrosion resistance is good, and the characteristic of both materials is similar, and for more integrally formed, price compares It is relatively inexpensive, reduce cost.

Brief description of the drawings

Fig. 3 is the structure diagram of water pipe head connecting tube.

Implication in figure represented by label：1- connecting tubes；2- adapter sleeves；3- rounded corners A；4- rounded corners B；5- is raised；6- Screw thread；Step in 7-；11- inner housings；12- pipe fittings junction；22- rounded corners C；23- grooves.

Embodiment

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,

As Figure 1-3, a kind of New type water pipe joint, including housing, the housing include adapter sleeve 2 and connecting tube 1, institute State connecting tube 1 and offer rounded corner integrally formed with inner housing 11 and pipe fitting junction 12, the left end inwall of the adapter sleeve 2 C22, the right side annular of the adapter sleeve 2 offer a stair-stepping groove 23, and the both ends of the inner housing 11 are supported respectively It is connected on rounded corner C22 and stair-stepping groove 23, connected mode of the present utility model is that the inner housing in connecting tube 1 directly expands Hole punching press is on the inwall of adapter sleeve 2 and makes its sealing, and sealing property is strong, and technical process is simple, and shaping speed is fast, and can Make the process in reaming punching press more smooth, and prevent the leakage of liquid.

Preferably, one end annular shaped on the inwall of the adapter sleeve 2 has step 7 in one, the inner housing 11 it is outer Footpath is connected on the interior step 7 of the adapter sleeve 2, and when interior step 17 abuts with the external diameter of inner housing 11, and one section of shape is close The space of envelope, realizes triple seal, even if the both ends of the surface of inner housing are not sealed well, also retrocession makes Liquid will not be revealed, and increase the sealing in adapter sleeve.
