Abstract
The utility model relates to a connecting device for pipes, in particular to a rapid connecting connector. Screw threads are formed on the inner wall of a plastic connector body with a cavity; a spiral sleeve with the screw threads is arranged between a cutting sleeve and the inner wall of the plastic connector body with the cavity. The structure enables the spiral sleeve to be separated from the plastic connector body separately, thereby discarding the welding technology, combining the pipes and connectors more closely, and replacing damaged parts at any moment. The utility model has the advantages of energy conservation, high working reliability, durability, convenience and easy assembly and disassembly.
Description
Technical field
The utility model relates to a kind of connection set of pipe, particularly a kind of Quick connecting joint.
Background technique
In the life, in order to realize the connection between the tube and tube, a kind of part commonly used is exactly a Quick connecting joint.China model utility CN2409405 discloses a kind of Quick connecting joint: 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 spring-back force effect 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 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.In order to solve the problem that annulus can loose in the fittings body, China model utility CN2603889 has done further improvement on the basis of CN2409405, the annulus employing is threaded in the fittings body inner chamber, though this Quick connecting joint annulus can not pitch because of welding between annulus and fittings body, guarantee that annulus is securely fixed in the fittings body, but, annulus and fittings body are one, annulus still can not separate separately with fittings body, in case annulus damages, even fittings body still is intact, also can only become waste product, waste material very.
The model utility content
Provide a kind of thereby the purpose of this utility model is to solve the deficiencies in the prior art and realize that with screw-casing replacement annulus screw-casing and fittings body can be split up into two separately, not only energy saving and operational safety height, durable in use, mounting or dismounting are convenient, are easy to Quick connecting joint.
The purpose of this utility model is achieved by the following technical solution: a kind of Quick connecting joint, comprise the plastic connector body that has cavity, place the seal ring in the fittings body cavity, cutting ferrule, the part that wherein is fastened in the fittings body cavity vertically is divided into several lobes, the outside of every lobe is provided with tooth, be provided with platform in the fittings body cavity, seal ring places on the platform, it is characterized in that: the plastic connector body inwall that has cavity is provided with spiral lamination, at cutting ferrule and have between the plastic connector body inwall of cavity and establish a screw-casing, described screw-casing comprises a square collet of smearing the angle, establish a sleeve column on collet, the outer wall of sleeve column is provided with the spiral lamination that is complementary with the plastic connector body spiral inner wall line that has cavity.
The beneficial effects of the utility model are: establish spiral lamination at the plastic connector body inwall that has cavity, at cutting ferrule and have the screw-casing of establishing a band spiral lamination between the plastic connector body inwall of cavity, such structure makes screw-casing to separate separately with the plastic connector body, has not only abandoned welding procedure, make pipe between joint more closely in conjunction with again, and can change wherein damaged components at any time, energy saving, the operational safety height is durable in use, mounting or dismounting are convenient, easily.

Embodiment
Now reach embodiment in conjunction with the accompanying drawings, the utility model will be further described:
Referring to Fig. 1 and Fig. 2, Quick connecting joint of the present utility model, comprise the plastic connector body 2 that has cavity 1, place the seal ring 3 in fittings body 2 cavitys 1, cutting ferrule 4, the screw-casing 5 that is positioned between cutting ferrule 4 and fittings body 2 cavitys 1 inwall constitutes, the inwall of fittings body 2 is provided with spiral lamination, and referring to Fig. 3, screw-casing 5 comprises a square collet 6 of smearing the angle, establish a sleeve column 7 on collet 6, the outer wall of sleeve column 7 is provided with the spiral lamination that is complementary with fittings body 2 spiral inner wall lines.Referring to Fig. 4, the part of cutting ferrule 4 in fittings body 2 cavitys 1 vertically is divided into several lobes 8, and the outside of every lobe 8 is provided with tooth 9, is provided with platform 10 in fittings body 2 cavitys 1, and seal ring 3 places on the platform 10.Fittings body 2 and screw-casing 5 can be metal.During use, will manage and inject cutting ferrule 4, then screw-casing 5 will be socketed in the outside of cutting ferrule 4, afterwards, screw-casing 5 is screwed in the cavity of fittings body 2 along fittings body spiral inner wall line, and screw-casing 5 revolves more inward, revolves tightly more, every lobe 8 of cutting ferrule 4 contracts tightly more, the tooth 9 in the outside of every lobe 8 is pressed inward, and the iron plate 11 that is embedded in every lobe 8 inboards like this will tightly be lived pipe clamp, and screw-casing 5 unclamps not supination, tooth 9 just outwards supports the state that recovers original, and screw-casing 5 is tightly blocked.
The above only is the preferred embodiment of model utility, not in order to last restriction model utility, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the present utility model.
