Abstract
A speed connecting joint comprises a joint body with a hollow cavity, a sealing ring provided in the joint body hollow cavity, a ferrule, and a ring provided between the ferrule and the joint body hollow cavity, the section of ferrule inside the joint body hollow cavity is vertically separated into a few flaps, each flap is provided with teeth, the joint body hollow cavity is provided with a platform therein, the sealing ring is provided on the platform, the exterior wall of the ring is clung to the interior wall of the joint body hollow cavity, the end of the ring adjacent to the joint body hollow cavity is trumpet shaped, the end of the ferrule on the trumpet shaped ring has a bigger outer diameter that the smallest inner diameter of the trumpet shaped hole of the ring, the special place lies in that the circular ring screw is connected inside the joint body hollow cavity. The utility model, in comparison with existing technology, has a reliability that the ring is free from loosening from the join body, and is convenient to install and dismantle.
Description
Technical field:
The utility model relates to a kind of connection set of pipe, particularly a kind of joint.
Background technique:
Existing Quick connecting joint, shown in patent " 00206199.6 ", main by the plastic connector body that has cavity, place the seal ring in the fittings body cavity, cutting ferrule, the plastic cement annulus that is positioned between cutting ferrule and fittings body cavity inner wall constitutes, the part that is fastened in the fittings body cavity vertically is divided into several lobes, the inboard of every lobe is provided with tooth, be provided with platform in the fittings body cavity, seal ring places on the platform, the outer wall of annulus is close to the inwall of fittings body cavity, that end near the fittings body cavity on the annulus is horn-like, the external diameter of that end that is positioned at horn-like annulus place on the cutting ferrule is bigger than the internal diameter of the minimum in the horn-like hole of annulus, and annulus is fixed in the fittings body cavity by the ultrasonic welding connection technology.During use, be subjected to the effect of spring-back force of the lobe of cutting ferrule, open outward the cutting ferrule termination, under the restriction in the horn-like hole of annulus, cutting ferrule can not withdraw from fittings body, afterwards, the pipe that external diameter and cutting ferrule internal diameter are matched inserts in the cutting ferrule, will manage toward the fittings body interpolation to pass in and out, until passing seal ring, like this, pipe with regard to sealed connection on fittings body, thereby realize quick purpose of connecting.This kind Quick connecting joint need be fixed in the fittings body inner chamber with ultrasonic bonding owing to annulus, and this welding method is subjected to the restriction of process conditions, the firm degree deficiency of welding in use looses annulus in the fittings body inner chamber, Quick connecting joint can not normally be used.
Summary of the invention:
The high Quick connecting joint of operational safety that goal of the invention of the present utility model is to provide a kind of annulus can not loose in the fittings body.
The utility model is to realize like this, comprise the fittings body that has cavity, place the seal ring in the fittings body cavity, cutting ferrule, be positioned at the annulus between cutting ferrule and fittings body cavity inner wall, the part that is fastened in the fittings body cavity vertically is divided into several lobes, the inboard of every lobe is provided with tooth, be provided with platform in the fittings body cavity, seal ring places on the platform, the outer wall of annulus is close to the inwall of fittings body cavity, that end near the fittings body cavity on the annulus is horn-like, the external diameter of that end that is positioned at horn-like annulus place on the cutting ferrule is bigger than the internal diameter of the minimum in the horn-like hole of annulus, and its specialization is that annulus is threaded in the fittings body inner chamber.During use, because annulus is to be threaded in the fittings body inner chamber, like this, annulus just can not guarantee that annulus is securely fixed in the fittings body inner chamber because of sealing-off between prior art annulus and fittings body looses.
The utility model compared with the prior art, have operational safety that annulus can not loose in the fittings body high, mounting or dismounting are convenient, be easy to advantage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model is mainly by the fittings body 2 that has cavity 1, place the seal ring 3 in fittings body 2 cavitys 1, cutting ferrule 4, the annulus 5 that is positioned between cutting ferrule 4 and fittings body 2 cavitys 1 inwall constitutes, the part of cutting ferrule 4 in fittings body 2 cavitys 1 vertically is divided into several lobes 6, the inboard of every lobe 6 is provided with tooth 7, be provided with platform 8 in fittings body 2 cavitys 1, seal ring 3 places on the platform 8, the outer wall of annulus 5 is close to the inwall of fittings body 2 cavitys 1, that end near fittings body 2 cavitys 1 on the annulus 5 is horn-like, the external diameter of that end that is positioned at horn-like annulus 5 places on the cutting ferrule 4 is bigger than the internal diameter of the minimum in annulus 5 horn-like holes, and its specialization is that annulus 5 is threaded in fittings body 2 inner chambers 1.Here, fittings body 2, annulus 5 can be with metal.
