Description
Technical field
The utility model relates to a kind of connection pipe fitting, especially relates to a kind of composite card shell type connection pipe fitting.
Background technique
Existing FERRULETYPE connection pipe fitting kind is many, but there is not a kind of close pipeline of caliber that can make things convenient for to connect, the FERRULETYPE connection pipe fitting that the pipeline that can make things convenient for big caliber to change little caliber again connects, so need usually could realize that through multiple tracks conversion big caliber changes the pipeline connection of little caliber, not only install cumbersome, increase cost of use, and increased the risk of pipe leakage.
Summary of the invention
The purpose of this utility model is to provide a kind of close pipeline of caliber that can make things convenient for to connect the composite card shell type connection pipe fitting that the pipeline that can make things convenient for big caliber to change little caliber again connects.
The purpose of this utility model solves by the following technical programs:
A kind of composite card shell type connection pipe fitting, it comprises the core body body that is provided with end difference, two groups of O shape circles, retainer ring, nut and crossover subs, and wherein retainer ring is the C shape ring that is set on the core body main body of end difference one side, and its internal diameter is less than the external diameter of end difference; Crossover sub is the hollow tubular body that is set on the core body main body of end difference opposite side, which is provided with outside thread and internal thread; Two groups of O shapes circle is separately positioned between core body body and the retainer ring and between core body body and the crossover sub; Nut sleeve is located at outside retainer ring and the crossover sub, and matches with the outside thread of crossover sub.
When the close pipeline of caliber is connected, earlier nut, retainer ring are enclosed within on the tubing, and retainer ring is placed in the nut; Subsequently the core body of core body body is injected the endoporus of tubing, and undertaken spacing by the end difference on the core body body; The connecting body that will need then to be connected with this tubing is enclosed within on the opposite side of core body body, and crossover sub is tightened on this connecting body by its internal thread, and is connected with nut by its outside thread; At last, by screwing nut, the opening of " C shape " retainer ring is constantly shunk and compress tubing, the convenient connection between the tubing of having realized having identical caliber thus and the connecting body, the sealing between core body body and tubing and the connecting body inwall has also been guaranteed in the O shape setting of enclosing simultaneously.When the different pipeline of caliber is connected, with reference to said method, earlier nut, retainer ring are enclosed within on the less tubing of caliber, and the core body of core body body injected its endoporus, then that caliber is bigger connecting body is enclosed within on the opposite side of core body body, need not to use crossover sub, directly by being threaded on connecting body and the nut nut is tightened on the connecting body, making things convenient between the tubing that can realize having different tube diameters and the connecting body is connected.
Also be provided with some roads annular tooth on the outer wall of described core body body, also be provided with some roads ring convex tendon on the inwall of described retainer ring.The setting of annular tooth and ring convex tendon makes between core body body outer wall and the pipe material inner wall and interlock in twos each other between retainer ring inwall and the outer pipe wall, plays the effect that strengthens sealability, strengthens axial anti-pulling intensity.
Be respectively equipped with O shape ring recess on the described core body body of described end difference both sides, two groups of described O shape circles are installed in respectively in the described O shape ring recess.O shape circle is arranged in the O shape ring recess on the core body body, easy for installation, help sealing between the inwall of core body body and tubing and connecting body.
Also be provided with trapezoidal groove on the end difference of described core body body; Described nut also is provided with tapered hole; The external diameter of described retainer ring is respectively equipped with the conical surface that matches with trapezoidal groove and tapered hole respectively less than the internal diameter of tapered hole and the internal diameter of trapezoidal groove on the two ends of described retainer ring.The setting of trapezoidal groove can be carried out spacing to tubing; Simultaneously, retainer ring is installed between core body body and the nut by cone match, helps the accurate location of retainer ring, prevents that retainer ring from deforming in screwing the process of nut, displacement etc., thereby can be pressed on the tubing it is fixed.
The advantage of connection pipe fitting described in the utility model is: both can be used for the direct connection between the close pipeline of caliber, the conversion that can be used for again between the pipeline of big caliber and little caliber is connected, and is easy for installation, firm, and sealing is strong, anti-pulling intensity height.

Embodiment
As depicted in figs. 1 and 2, composite card shell type connection pipe fitting described in the utility model includes core body body 1, O type circle 2, retainer ring 3, nut 4 and crossover sub 5.
Core body body 1 is provided with end difference 13, is provided with some roads annular tooth 12 on the outer wall of the core body body 1 of end difference 13 1 sides, is provided with twice O shape ring recess 11 in annular tooth 12.On the core body body 1 of end difference 13 opposite sides, also be provided with O shape ring recess 11 one.O type circle 2 is provided with respectively and is installed in the described O shape ring recess 11.
Also be provided with trapezoidal groove 14 on the end difference 13 of core body body 1, nut 4 also is provided with a tapered hole 41 in the place ahead of its screw thread, and the external diameter of retainer ring 3 is respectively less than the internal diameter of tapered hole 41 and the internal diameter of trapezoidal groove 14.
The two ends of retainer ring 3 respectively are provided with a conical surface, retainer ring 3 is set on the core body body 1 of end difference 13 1 sides (being provided with a side of annular tooth 12) and is built in the nut 4, and the conical surface at its two ends matches with the trapezoidal groove 14 of core body body 1 and the tapered hole 41 of nut 4 respectively.
