Abstract
The invention relates to a pipe connecting piece, in particular to a push-in type quick pipe connecting piece, which comprises a body and is characterized in that: a seal ring and a pipeline locking device are sequentially embedded in the body; the pipeline locking device is in pressure welding fit with the seal ring; the inner wall of the body is provided with a groove; a bump matching with the groove is arranged on the outer wall of the pipeline locking device; and the bump is in buckling fit with the groove. In the push-in type quick pipe connecting piece, a claw sheet has an independent structure and does not need injection molding, so the push-in type quick pipe connecting piece solves the problem that plastics surround the claw sheet in an injection molding process. Because the inner wall of the body is provided with the groove and the bump is arranged at a corresponding position on the outer wall of a fixed ring, the pipeline locking device is fixedly connected with the pipe connecting piece body through the buckling of the bump and the groove. Because the pipeline locking device adopts a buckling way entirely and does not need cementing or welding, the assembly is convenient. The push-in type quick pipe connecting piece of the invention completes the connection between a pipe and the pipe connecting piece only by inserting the pipe into the pipe connecting piece, and has the advantages of simple structure, convenience, practicability, stable connection and good leak tightness.
Description
Technical field
The present invention relates to a kind of pipe connector, be specifically related to a kind of push-in type quick pipe connecting piece.
Background technique
For Related products such as water purifiers, the sealing of pipeline is most important, and most products leak easily, leak gas at the pipe joint place, has all brought a lot of unnecessary troubles for Consumer and manufacturer.Pipe connector on the market generally is divided into two kinds: original nut check formula pipe connector and with lock pipe connector of common pawl formula.
For nut check formula pipe connector, have following defective: 1, owing to be that clamping type connects, to the quality requirement height of pipe, pipe diameter is slightly larger than normal specifications, may insert to enter, and the smaller instability that then connects of diameter causes and leaks; 2, the coaxality of pipe require high, can unbalance stress if pipe thickness is inhomogeneous, cause and leak; 3, sealing is relevant with the degree of tightness of nut, twists tightly then can not leak, and each root pipe is installed all needs fastening nut as requested, and working efficiency is low, and the poor stability of product; 4, the hardness of tubing requires height, if hardness is not enough, then repeatedly uses same pipe, and can cave in the joint, thereby leak, and so just increased the cost that retubes; 5, the mounting pipe period of the day from 11 p.m. to 1 a.m needs to install additional pipe close in the pipe, can prevent that so just pipe is crushed out of shape, and greatly reduces working efficiency and install pipe close additional, if the operator is leaked and to be put pipe close in addition, is difficult for being found when dispatching from the factory test, thereby has increased the defect rate of product; 6, add pipe close in the pipe after, its sectional area reduces, flow also reduces, and has so just increased the pressure of pipe, has shortened the working life of pipe.
For with lock pipe connector of common pawl formula,, also there is following defective: 1, have only 4 pawls and pipe clamping on the calvus though pipe is pegged graft conveniently, wedging position is less, the fixed position of pipe can produce skew when pressure, causes pipe to tilt, and causes and leaks; 2, the calvus link is that expansion is connected with the pipe connector body, its quality of connection instability, and when the pipe internal pressure became big, the calvus link is skew outwards, caused pipe to tilt, and caused and leaked; 3, calvus and calvus link are molding and forming, and plastics can wrap up calvus when injection moulding, and empty card can take place when calvus and pipe clamping like this, and the working process of calvus link is slow in addition, and manufacturing efficiency is low; 4, the calvus link is with after the pipe connector body is connected, the outside needs the socket locking plate to increase the stability of product, when pressure hour, because the effect pipe of locking plate can not produce inclination, when pressure was big, the calvus link is skew outwards, and this moment, locking plate came off easily, can cause pipe to tilt after locking plate comes off again, cause and leak.
Therefore the pipe connector that designs a kind of quick connection, good seal performance is very necessary.
Summary of the invention
At problems of the prior art, the objective of the invention is to is providing a kind of technological scheme of push-in type quick pipe connecting piece.
Described push-in type quick pipe connecting piece, comprise body, it is characterized in that rabbeting successively in the described body seal ring and pipeline locking device are set, pipeline locking device and seal ring press fit, inner body wall is provided with groove, the outer wall of pipeline sealing device is provided with the projection that matches with groove, and projection cooperates with the groove clamping.
Described push-in type quick pipe connecting piece, it is characterized in that described pipeline locking device is made up of calvus fixing frame, calvus, retainer ring and buckle, place calvus on the calvus fixing frame, the top of calvus fixing frame is provided with the groove one that matches with retainer ring bottom projection one, retainer ring cooperates by projection one, groove one clamping with the calvus fixing frame, the interior projection that the inside bottom setting of retainer ring matches with the outer projection in buckle bottom, buckle cooperates by outer projection, interior projection clamping with retainer ring.
Described push-in type quick pipe connecting piece is characterized in that on the outer wall of described retainer ring projection being set, and projection cooperates with groove clamping on the inner body wall.
Described push-in type quick pipe connecting piece is characterized in that described calvus is set to 10 pawls according to the size of body or more than 10 pawls.
Above-mentioned push-in type quick pipe connecting piece, calvus is an absolute construction, do not need injection moulding, plastics surround the problem of calvus when having solved injection moulding, and calvus adopts stainless steel material to make, not yielding, on the calvus fixing frame mounting groove is set, calvus is easy for installation, and calvus can be according to the pawl number of the tube designs varying number of different size, guarantee that the pipeline locking device is connected with pipe multitool face, pipe is difficult for tilting; The seal ring inboard is the plane, and outside design has projection, and the projection in the outside holds out against inner body wall, increased elasticity, it is firm that seal ring is connected with body, alleviated the push-on force of pipe, when pipe insertion tube fitting body, pipe is that face contacts with the seal ring inwall, and when in the pipe pressure being arranged, the seal ring outer wall gradually becomes the face contact with contacting from a contact of inner body wall, pressure in the pipe is big more, the surface of contact of seal ring outer wall and inner body wall is also big more, and it is good more to seal, antileaking; Inner body wall is provided with groove, and the relevant position on the retainer ring outer wall is provided with projection, and the clamping of projection and groove makes pipeline locking device and pipe connector body be connected firmly, and is not offset; The whole snap fit that adopts of pipeline locking device does not need to glued joint or welding, and is easy for installation, the manufacturing efficiency height; The present invention is simple in structure, and is convenient and practical, only pipe insertion tube fitting body promptly need be finished being connected of pipe and pipe connector, connect stablize, good airproof performance.
