Abstract
The utility model relates to a pipe joint and the technical field of a special clamping head. The pipe joint is designed for connecting a thin wall pipe. The pipe joint is provided with a pipe joint body and a sealing ring. The utility model is characterized in that the port part of the pipe joint body is provided with an annular bulge, the inner side of the annular bulge is provided with an annular groove, and the inner part of the annular groove is matched with the sealing ring. The special clamping head is divided into an upper and a lower or a left and a right two clamping blocks, the inner side of each clamping block is provided with a circular arc-shaped hollow cavity, the surface of the hollow cavity is provided with a circular arc-shaped groove, and the end surface is a local regular polygon. The utility model has the advantages of simple structure, easy manufacturing production and low cost, and is suitable for being popularized and used on the pipe joint.
Description
The utility model relates to pipe joint and special carrier technical field thereof.
Along with living standards of the people improve constantly, family has used the stainless steel pipe as running water pipe in decoration now, and this stainless steel pipe has been generally the material saving, has saved cost, adopts the few thin walled tube of loss.The relevant pipe joint technology report of domestic patent is more, but generally is to be suitable for hard tube or flexible tube joint, and is less about connecting Thin-wall Tube joint technology report.As the patent No. is 98228287.7 Chinese patent " oblique mouth metal ring locking rectangular loop sealed pipe joint ", it has placed outside thread outside pipe fitting, tubaeform inner conical is arranged on the aperture, suit back of the body cap on pipe, insert in the pipe fitting body opening behind oblique mouth metal ring and the rectangular rubber circle, tighten back of the body cap, oblique mouth metal ring and rectangular rubber figure are advanced in the internal taper hole of pipe fitting, internal taper hole is closely contacted with external cone, with the pipe banding, it can use thin walled tube, its shortcoming: part is more, the production and processing technology step is more, and cost of production still can not finely reduce, and influences it and promotes the use of.
First purpose of the present utility model is to provide a kind of simple in structure, production and processing is easy, cost is low pipe joint.
Second purpose of the present utility model be to provide a kind of simple in structure, connect the special carrier that uses for above-mentioned pipe joint.
Realize that the first purpose technological scheme of the present utility model is such: this pipe joint, include union body, seal ring, it is characterized in that described union body port part has the ring-type protuberance, ring-type protuberance inboard is an annular groove, the liner seal ring.
The aforementioned tube fittings body also is provided with recessed of the uniform in the form of a ring location of anchor clamps compactings near port part.
Realize that the second purpose technological scheme of the present utility model is such: this pipe joint special carrier, it is characterized in that chuck is divided into up and down or about two fixture blocks, fixture block has circular arc cavity, cavity surface also to be provided with the circular groove that cooperates and make its radial contraction with union body port part ring-type protuberance in the middle of pressing close to the pipe joint inner side surface.
Pipe joint structure of the present utility model is very simple, easy processing, cost of production are low, it is also very convenient to use, and suits to apply on sheet-metal duct connects.And chuck is also very simple, is contained in the last use of anchor clamps union body port part ring-type protuberance radial contraction is sealed up, and make recessed of location.Can on multiple instrument, use.
Description of drawings:
Fig. 1. pipe joint complete section figure;
Fig. 2. pipe joint user mode figure;
Fig. 3. chuck uses schematic representation.
Below in conjunction with description of drawings embodiment of the present utility model is further described:
As shown in the figure, this pipe joint includes union body 1, seal ring 2, in union body 1 port part ring-type protuberance 3 is arranged, ring-type protuberance inboard is an annular groove, liner seal ring 2, when it uses, the union body port part is inserted thin walled tube 5 as Stainless Steel Tube, copper pipe etc., with special fixture compacting, ring-type is swelled shrink in 3 radius vectors, make seal ring 2 seal up gap between the tube wall, and make union body be suppressed with uniform in the form of a ring location recessed 4 near port part, positioning and fixing between union body and the thin-walled tube is difficult for becoming flexible like this, and sealing effect is better.This union body can be made threeway, two logical or curved head type structures, and wherein certain port is provided with internal thread or outside thread, and with the convenient hard tube that connects, its using effect is no longer carefully stated here referring to Fig. 2.Whole pipe joint can adopt Stainless Steel Tube or copper pipe material to make.Its special carrier be divided into up and down or about two fixture blocks 6, fixture block has semicircular cavities 7 in the middle of pressing close to the pipe joint inner side surface, cavity surface also is provided with the semi-circular recesses 8 that cooperates and can make its radial contraction with union body 1 port part ring-type protuberance 3, fixture block 6 bilateral end faces are for suppressing the local regular polygon structure 9 of locating recessed 4, as regular hexagon, octagon or the like.When up and down or left and right sides fixture block when fitting, cavity surface just forms toroidal cavity, and make union body port part ring-type protuberance 2 suitably make radial contraction, seal up gap between the tube wall, the side end face becomes regular polygon simultaneously, suppress the location recessed 4 at pipe joint and between taking on the tube wall, play necessary positioning and fixing effect, prevent to become flexible.
