Abstract
The utility model discloses a crimping connecting pipe fitting comprising a body with a core body, an O-shaped ring, a retain ring and a stainless steel bushing, wherein an axial groove and a plurality of paths of annular convex column bars are arranged on the outer wall of the core body; and the outside diameter of the installed O-shaped ring is not more than that of the annular convex column bar. The utility model has the advantages that: with water leakage indication, the pipe fitting is conveniently displayed to be crimped or not; and the crimping connecting pipe fitting has favorable sealing performance and high tensile strength and is convenient for installation.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, especially relates to the tongs press type connection pipe fitting.
Background technique
The structure of common tongs press type connection pipe fitting is: be embedded with O type circle on the core body outer wall of its main body, main body is provided with back-up ring, stainless steel sleeve is set in outside the main body and snaps in the back-up ring, during connection, tubing is inserted in the cavity between stainless steel sleeve inwall and the main body outer wall, the tool using pincers are pressed the stainless steel sleeve distortion, tubing also is out of shape simultaneously and closely contacts with core body, O type circle can play the effect of sealing, usually the external diameter of the outer O type circle that embeds of core body is greater than the external diameter of core body, therefore fashionable at the tubing cover, formed between O type circle and the pipe material inner wall and contacted, have certain sealability, after the water flowing when hydraulic pressure is not high, water can not leak, and therefore can't judge whether to carry out pincers and press, and is easy to cause omit clamp the phenomenon of pressing, if in going into wall coil road or buried pipeline, use, the maintenance difficulty that produces after revealing is bigger, and required expense is huge, has bigger installation risk.And O type circle is easy to generate distortion under extruding usually, thereby causes sealability to descend, and is easy to generate leakage.
Summary of the invention
The purpose of this utility model provide a kind of can show whether clamp press and install easily, better the leak tongs press type connection pipe fitting of indication of band of sealability.
Technical solution of the present utility model is: a kind of tongs press type connection pipe fitting, the body, O type circle, back-up ring and the stainless steel sleeve that comprise the belt carcass body, on described core body outer wall, be provided with the groove of axial setting, and be provided with some roads annular projection muscle on the core body outer wall, the external diameter after described O type circle is installed is not more than the external diameter of annular projection muscle.
The core body outer wall is provided with annular projection muscle, external diameter after its external diameter is installed greater than O type circle, like this after pipe inserts, its inwall contacts annular projection muscle and can not contact O type circle, therefore do not form sealing, when occurring omitting the situation of pincers pressure, the water after the water flowing is easy to flow out along the groove that axially is provided with on the core body outer wall, can reflect intuitively rapidly that whether pipe fitting is by the pincers pressure.In addition, O type circle is difficult for deforming, and the sealing effect after pincers are pressed is better.Annular projection muscle external diameter presses the internal diameter at pipe deformation position, back big than pincers, can improve the join strength of pipe fitting and pipe.
Be equipped with knuckle-tooth on the described core body outer wall, can shunt along the current that groove flows out, make the current of outflow very even, whether the convenient pipe fitting that reflects is intuitively pressed by pincers.
On described back-up ring, be provided with sight hole, when tubing enters, can observe whether being in place easily.
The utility model has the advantages that: have the indication of leaking, can show easily whether pipe fitting is pressed by pincers, good seal performance, the tensile strength height, easy for installation.

Embodiment
Embodiment:
Consult Fig. 1-3, a kind of tongs press type connection pipe fitting comprises main body 1, O type circle and the back-up ring 4 of belt carcass body 2, and wherein main body 1 is provided with O type ring recess 6, and O type circle 5 is arranged in this O type ring recess 6.Be arranged with the back-up ring 4 of plastics on the main body 1, stainless steel sleeve 10 is set in outside the main body 1 and snaps in the back-up ring 4.Core body 2 outer walls are provided with four grooves 8 that axially are provided with, and are provided with some roads annular projection muscle 7 on core body 2 outer walls, and the external diameter after O type circle 5 is installed is not more than the external diameter of annular projection muscle 7.Also be equipped with knuckle-tooth 9 on the outer wall of core body 2.The periphery of back-up ring 4 is provided with sight hole 11.
During installation, pipe is inserted between stainless steel sleeve 10 and core body 2 outer walls, press if forget pincers, when water flowing was exerted pressure, current were easy to flow out by the groove on core body 2 outer walls 8, and through knuckle-tooth 9 shuntings that ring is established, were easy to be observed.
In the present embodiment, O type circle 5 is arranged on O type ring recess 6, and the external diameter after it is installed is not more than the external diameter of annular projection muscle 7, therefore after pincers are installed are pressed, can bear bigger radial pressure and does not bear axial pressure, the leakage danger of having avoided axial deformation to bring.And after the pincers pressure, the internal diameter at pipe deformation place has improved the anti-pulling intensity when pipe connects less than the external diameter of annular projection muscle 7.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
Claims (3)
1. tongs press type connection pipe fitting, the body, O type circle, back-up ring, the stainless steel sleeve that comprise the belt carcass body, it is characterized in that: the groove that on described core body outer wall, is provided with axial setting, and be provided with some roads annular projection muscle on the core body outer wall, the external diameter after described O type circle is installed is not more than the external diameter of annular projection muscle.
