Description
Technical field
It the utility model is related to a kind of pipe joint, more particularly to a kind of rubber fittings knot that can be circumnutated with steel skeleton
Structure, belong to rubber system device technical field.
Background technology
Bending rubber joint is commonly called as rubber soft joint, and its product is widely used in water, electricity, chemical industry, vessel system, mainly
Performance high pressure, the good, noise-reducing of elasticity, light weight, damping are dynamic, easy for installation, using flexible, are easy to change and repair, have simultaneously
There is the features such as acidproof, alkaline-resisting, oil resistant.The natural trend of resistance to weather can extend the product automatically in use.Traditional rubber
Connecting hose, metal flange is set in connecting portion mostly, other positions are based on rubber, by bolt by gold during connection
Category flange is fastened on other fixture or another ring flanges.Because the main body section of joint is that rubber is made, therefore axially,
Laterally, the amplitude that circumnutates of angular displacement is larger, but the unfavorable factor brought is：Body of rubber deflection is big, easy to aging, not only can
Season cracking is produced, causes service life shorter, and connective stability is poor.
The content of the invention
For the technical deficiency of traditional rubber soft joint as stated in the Background Art, the utility model provides a kind of steel skeleton can
Circumnutate rubber fittings, has both made the adaptable of pipe joint, makes the connective stability of pipeline good again.
The utility model is implemented by the following technical programs：A kind of steel skeleton can circumnutate rubber fittings, by steel skeleton and
Vulcanize it is rubber combined form, its interface connects external pipe respectively, and connecting portion is tied tight with clip, it is characterised in that：
Described steel skeleton is metal sleeve, and the pore of sleeve pipe is the through flow hole of pipe joint；
The described vulcanization vulcanization of rubber is coated on the periphery of metal sleeve, and both ends are stretched out outside the both ends of metal sleeve,
Small tubaeform tie tight is held to shrink interface tube in composition greatly；
The vulcanization rubber bodies of metal sleeve end periphery are provided with axial annular groove in the contraction interface tube；
One end of the external pipe, through the contraction interface tube of vulcanization rubber, insert in axial annular groove.
Further, the groove side rubber bodies circumference of the axial annular groove is provided with half circular boop to groove internal projection；
Further, outer chamfering and interior chamfering are respectively equipped with described external pipe connection end interface；
Further, the vulcanization rubber exterior of the axial rings groove location is provided with supply clip circumferentially to tie external pipe tight half
Circular groove.
Favorable attributes of the present utility model are：
1st, metal sleeve is provided with rubber fittings, makes pipe joint is both flexible to circumnutate, there is connective stability again
Good, the ability that resistance significantly deforms is strong, improves service life；
2nd, set tubaeform tie tight to shrink interface tube, while axial annular groove is set, and tied tight by clip outside vulcanization rubber
The half slot in portion, strengthen the sealing of connection, reliability increase, while convenient disassembly.
