Abstract
The utility model provides a quick hydraulic pipe joint which consists of a left joint body, a seal ring, a connecting nut and a right joint body. The outer edge of the right end of the left joint body is threaded, the left joint body and the right joint body are respectively provided with a concave spherical surface and a convex spherical surface, which are matched with each other, and the other ends of the left joint body and the right joint body are respectively provided with an inner screw thread for being connected with a hydraulic pipeline. The left joint body and the right joint body are matched with each other, and then are connected with each other by the connecting nut. One end of the connecting nut is provided with a lug boss, and when the connecting unit is used for connecting, the connecting nut is screwed into and matched with the outer thread of a connecting body with the concave spherical surface from one end of the joint body with the convex spherical surface, so that the connecting nut can be well used for connecting. Meanwhile, the seal ring is arranged on the joint body with the convex spherical surface, so that the tightness of the quick hydraulic pipe joint provided by the utility model can be guaranteed. The quick hydraulic pipe joint is simple in structure, easy to produce, good in tightness, and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to Hydraulic Field, is specifically related to a kind of hydraulic pipe line connection set.
Background technique
Often use various pipe joints in the hydraulic plumbing system, mainly contain: welding type, FERRULETYPE and flared type.Bite type fittings commonly used is made up of three parts: fittings body, cutting ferrule and nut.There is tilted conical surface at the two ends of cutting ferrule, when cutting ferrule and nut sleeve after inserting fittings body on the steel pipe, when screwing nut, fit with the fittings body conical surface in the cutting ferrule front end outside, utilizes the distortion of cutting ferrule to block pipe and seal.The required precision of cutting ferrule is higher, and repeatedly after the dismounting, the reliability of sealing reduces, and leaks easily.
Summary of the invention
The purpose of the utility model provides a kind of easy to connect, and is simple in structure, the reliable sealing hydraulic fitting.
The fast hydraulic pressure pipe joint of the utility model comprises two fittings bodies, an attaching nut and a seal ring.A left side fittings body right-hand member and right connector body left end have the concave spherical surface and the protruding sphere of a cooperation, and the left fittings body right-hand member outward edge that has concave spherical surface is screw-like, about two fittings bodies be fixed together by the attaching nut.Attaching nut's a end has boss, and when connecting two fittings bodies, nut contacts with attaching nut's raised head face until the right side of left fittings body from the right-hand member precession of turning left.Seal ring is installed in the sphere at that has protruding spherical joint body.The left end of left side fittings body and the rear end of right connector body have internal thread respectively, are connected with hydraulic tubing.
The usefulness of the utility model is:
The surface of contact of two fittings bodies is a sphere, can avoid the leakage of tilting to cause because of installing.Sphere contact simultaneously makes dismounting more convenient, and repeatedly dismantles the destruction of sphere less; Seal ring has played good seal action as on the right connector body; Attaching nut's a end has boss, makes easy to connect reliably, and this hydraulic fitting is simple in structure, be prone to produce, and good airproof performance, easy accessibility is the creativeness transformation to existing hydraulic fitting.
Description of drawings
Fig. 1 is the section of structure of the fast hydraulic pressure pipe joint of the utility model.
1, left fittings body; 2, seal ring; 3, attaching nut; 4, right connector body.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
As shown in Figure 1; The fast hydraulic pressure pipe joint of the utility model comprises left fittings body 1 and right connector body 4; The right-hand member inside of left side fittings body 1 have one be concave spherical surface slotted eye; There is the protruding sphere that matches with left fittings body 1 right-hand member concave spherical surface slotted eye the left side of right connector body 4, and the right-hand member external process of left fittings body 1 has screw thread.Left and right two fittings bodies are fixed together by attaching nut 3.An end of attaching nut 4 has boss, and when connecting two fittings bodies, attaching nut 4 screws from right-hand member, contacts until the right side of raised head face with left fittings body 1.Seal ring 2 is installed in right connector body 4 near protruding sphere bottom end position.In order to connect hydraulic tubing, the right-hand member of the left end of left fittings body 1 and right connector body 4 has interior threaded hole respectively.When joint connects, earlier seal ring 2 is installed on the right connector body 4, the protruding sphere with right connector body 4 inserts in the concave spherical surface of left fittings body 1 then, from right-hand member precession attaching nut 4, it is tightened then.Attaching nut 4 raised head face is contacted with the right side of left fittings body, thereby play the effect of connection.
