Abstract

The utility model relates to a quick pipe joint which is used for connecting flexible pipes, comprising a joint body, two C-shaped clamping rings, and a tightening nut. The external surfaces of the two ends of the joint are respectively provided with an external thread and an inserting part inserted into the flexible pipe; the external surface of the inserting part is provided with a plurality of annular grooves in which sealing O-shaped rings are arranged; the flexible pipe which is sheathed in the inserting part is externally sleeved with the C-shaped clamping rings and then is sleeved with the tightening nut whose internal thread can be engaged with the external thread of the joint body; two flexible pipes can be connected by tightly screwing the tightening nut. The utility model has the advantages of rapid and simple connection, strong sealing capability, difficult leakage of fluid, etc.

Description

Quick-acting pipe connection
The utility model relates to a kind of quick coupling that connects flexible tube.
Along with flexible tube such as plastic tube cost reduce, be widely used in the pipelines such as various machines, chemical industry, medicine production, food production urgent further and significance so the quick coupling of flexible tube seems.Pipe joint as the plastic tube of patent No. 93221049.X, the joint of the polyethylene pipe that Korea S standard K S B1564 is made improves, this joint can be kept sealability uniformly, resist plastic tube because variation of temperature or the aging distortion that causes reduce the fluid leakage that takes place between fittings body and the pipe.But the pipe joint of the plastic tube of this patent still has 2 soft big defectives: 1. the pipe joint of the plastic tube of this patent can only be used to connect hard tube and is connected with flexible tube, and pipe joint two ends can not connect two flexible tubes simultaneously fast in other words; 2. the pipe joint of the plastic tube of this patent adopts packing ring, is general O type copper ring, and radial contraction power is less, means the opposing plastic tube because temperature variation or the aging deformability that causes are also soft poor.
The utility model is the technological deficiency of pipe joint in view of the above, and its purpose is to provide a kind of two ends can connect two flexible tubes fast simultaneously and can resist flexible tube is kept even sealability because of temperature variation or the aging distortion that causes quick coupling more strongly.
Quick coupling of the present utility model is to realize like this, quick coupling body two ends respectively have the insertion portion in an outside thread and the insertion flexible tube, flexible tube is enclosed within insertion portion, this pipe overcoat C type packing ring, however overlap again one have internal thread can with the tightening nut of fittings body outside thread engagement.Screw tightening nut compressing C type packing ring and constantly shrink, flexible tube closely is stuck between insertion portion and the C type packing ring.And described insertion portion outer surface has many annular grooves, and soft sealing O type ring is housed in the annular groove, and the internal surface of C type packing ring has two bulge loops, and respectively there is a conical surface its exterior edge face.
Description of drawings.
Fig. 1. the exploded view of quick coupling, wherein made broken section.
Fig. 2. the erection drawing of quick coupling and flexible tube.
Fig. 3. the assembling user mode figure of quick coupling and flexible tube.
Below in conjunction with accompanying drawing quick coupling of the present utility model is further described.
The quick coupling of this model utility at first comprises a fittings body (5) as shown in Figure 1, and fittings body two ends respectively have an insertion portion (7) that inserts in the flexible tube, and fittings body two end outer surfaces have an outside thread (6) simultaneously.The outer surface of this insertion portion also has some annular grooves (3), and soft sealing O type ring (4) is housed in the annular groove, also has a conical surface (2) on its internal end surface of two ends of fittings body.
Secondly these quick coupling two ends respectively also comprise a C type packing ring (9), this packing ring internal surface has two bulge loops (1), and packing ring appearance side respectively has the conical surface (2) on a conical surface (8) and the fittings body internal end surface and the conical surface (11) of tightening nut (12) internal surface to be complementary.
These quick coupling two ends also comprise a tightening nut (12) at last, and its internal surface has the internal thread (10) that can be meshed with the outside thread (6) of fittings body one end outer surface, and its outer inner also has conical surface (11).
When this quick coupling used, shown in Fig. 2-3, at first two flexible tubes (13) respectively were inserted in an insertion portion (7) of fittings body, yet this manages a C type of overcoat packing ring (9) again, and C type packing ring overlaps a tightening nut (12) outward again.When screwing tightening nut (12), C type packing ring (9) be subjected to the conical surface of fittings body and binding thread conical surface extruding and constantly shrink, flexible tube (13) is closely contacted on insertion portion (7) outer surface.And insertion portion (7) outer surface has some soft sealing O type rings (4), and C type packing ring internal surface also has two bulge loops (1) simultaneously, so evenly and strong sealability is arranged between fittings body and the flexible tube, makes fluid be difficult for leaking out.
Quick coupling of the present utility model has the fast distortion simple and easy, that resist soft tube Yin Wendu variation or wear out and cause strongly of connection soft tube, and uniform sealability is arranged, and makes fluid be difficult for the advantages such as leakage.

Claims (3)

1, a kind of quick coupling that is used to connect soft pipe fitting, it is characterized in that: its two end of the fittings body of quick coupling (5) respectively has an outside thread (6) and inserts the insertion portion (7) of flexible tube, and one is enclosed within the nearly tight ring of C type (9) on the flexible tube and one and has the tightening nut (12) that internal thread (10) can be meshed with quick coupling extracorporeal thread (6).
2, quick coupling according to claim 1 is characterized in that described insertion portion (7) surface has some annular grooves (3), is equipped with soft sealing O type ring (4) in the annular groove (3).
3, quick coupling according to claim 1 is characterized in that described C type packing ring (9) internal surface has two bulge loops (1), and outer end face respectively has a conical surface (8).
