Abstract
The utility model relates to a quick-acting pipe joint assembly, comprising a joint element (1) and a locking ring (2) which is sheathed outside the joint element. The joint element comprises a hexagonal joint body (1-2) which is positioned at the middle part of the joint element, an inverted tapered joint (1-1) which is positioned at the upper part of the joint element, and a connecting screw bolt (1-3) which is positioned at the lower part of the joint element. A chamfering (1-1-1) is arranged at the top end of the joint, a section of circular ring surface (1-1-2) is arranged below the chamfering, and a ring groove (1-1-3) for sheathing in a sealing ring (3) is arranged below the circular ring surface. The outer surface of the locking ring is in an inverted tapered shape, the upper inner surface of the locking ring is an inverted tapered surface, the lower inner surface is a circular ring surface; the radius of the ring surface is bigger than the radius of a ring surface at the inserting end of the joint, and the difference value r is smaller than the wall thickness of all suitable water pipes or air pipes. The pipe joint assembly has the advantages of simple structure, low cost and convenient operation; the utility model also has the advantage that water pipes or air pipes can not be damaged in the course of operation.
Description
The utility model belongs to connection pipe fitting, is specifically related to a kind of quick coupling assembly that connects soft water pipe or tracheae that is applicable to.
Widely used simple and easy hose coupling has a tubular body at present, and an end is a threaded ends, and the middle part is the hexagonal body, and the other end is the flexible pipe insertion end, and its outer surface has a plurality of annular grooves.During use, flexible pipe is inserted the insertion end of adapter body, with metal pipe collar locking flexible pipe, flexible pipe produces distortion, is close to the outer surface of adapter body insertion end, forms chucking power, guarantees sealing then.This Placement very easily causes the permanent plastic deformation of flexible pipe even destroys flexible pipe; And another kind of widely used quick hose joint is made of two assemblies.Wherein first cylindrical shell is similar to above-mentioned simple and easy hose coupling, but changes the flexible pipe insertion end insertion end of the second tubular assembly into, and an end of the second tubular assembly is connected the insertion end that the other end is a flexible pipe with first cylindrical shell, similar to the flexible pipe insertion end of simple and easy joint.Therefore, there is the shortcoming of above-mentioned simple and easy hose coupling in this quick hose joint equally except that easy disassembly.
The purpose of this utility model is to provide a kind of quick coupling assembly easy to use, simple in structure.
Quick coupling assembly of the present utility model, it is characterized in that comprising adapter piece and be set in the outer locking ring of adapter piece, described adapter piece comprises the hexagon fittings body that is positioned at the adapter piece middle part, be positioned at the joint of inverted cone on adapter piece top and the connecting bolt that is positioned at the adapter piece bottom, there is a chamfering on the top of described joint, so that the insertion of soft water pipe or tracheae, one section toroidal surface is arranged under the chamfering, under this toroidal surface, offer an annular groove that is used to be inserted in seal ring, the outer surface of described locking ring is inverted cone, its top inner face is an inverted cone surface, its tapering is slightly larger than the tapering of joint, the lower inner face of locking ring is a toroidal surface, its anchor ring radius is greater than the anchor ring radius of joint insertion end, and its difference r is less than the soft water pipe that is suitable for or the wall thickness of tracheae.
During use, the connecting bolt of the bottom of adapter piece is fixed in the corresponding tapped hole, then soft water pipe or tracheae is enclosed within on the inverted cone joint, on carry locking ring, water pipe is extracted in examination, the check fastness is moderate until fastness.When the joint of flexible pipe insertion tube joint, because the elastoplasticity of flexible pipe self, form a conical outer surface consistent with the joint insertion end at the outer surface of insertion end, draw the locking ring of taper firmly, locking ring compressing flexible pipe, after making it to be out of shape slightly, locking ring can be positioned on the flexible pipe fully.When the hydrodynamic pressure in the flexible pipe increases, flexible pipe is under the effect of hydrodynamic pressure, the trend of leaving joint is arranged, and when hydrodynamic pressure was enough big, flexible pipe began to leave joint, at this moment, be attached to the also same moved further of locking ring on the flexible pipe outer surface, cause the gap between the joint conical surface and the locking ring conical surface to dwindle, locking ring and joint increase the chucking power of flexible pipe, the power of compressing seal ring also strengthens, thereby has guaranteed the reliability of hose coupling.Normal temperature test down shows that under the hydraulic pressure of 16Bar, water pipe still remains intact, and general work water pressure has only about 4Bar.
Quick coupling assembly dismounting of the present utility model is also very convenient, after hydrodynamic pressure discharges, the distortion that flexible pipe produces under the effect of hydrodynamic pressure disappears, flexible pipe returns to normal state, the chucking power of this moment reduces, can be easily flexible pipe and locking ring be pushed back the bottom of joint together, extract flexible pipe.Because the toroidal surface of locking ring and the joint that contact with flexible pipe is an anchor ring completely, therefore, this joint can not cause tangible plastic deformation of flexible pipe or damage, does not need to lock with locking pipe collar yet.
Quick coupling assembly of the present utility model, simple in structure, use also very convenient; As adopting nylon or high strength plastics injection moulding once-through, material and processing cost are all very low.
Below in conjunction with accompanying drawing quick coupling assembly of the present utility model is described further:
Fig. 1 is the structural representation of the utility model quick coupling assembly.
Fig. 2 is the user mode schematic representation of the utility model quick coupling assembly.
As depicted in figs. 1 and 2, quick coupling assembly of the present utility model, comprise adapter piece 1 and be set in adapter piece 1 locking ring 2 outward, described adapter piece 1 comprises the hexagon fittings body 1-2 that is positioned at adapter piece 1 middle part, be positioned at the joint 1-1 of inverted cone on adapter piece 1 top and the connecting bolt 1-3 that is positioned at adapter piece 1 bottom, there is a chamfering 1-1-1 on the top of described joint 1-1, one section toroidal surface 1-1-2 is arranged under the chamfering 1-1-1, under this toroidal surface 1-1-2, offer an annular groove 1-1-3 who is used to be inserted in seal ring 3, the outer surface of described locking ring 2 is inverted cone, its top inner face is an inverted cone surface, the lower inner face of locking ring 2 is toroidal surfaces, its anchor ring radius is greater than the anchor ring radius of joint insertion end, and its difference r is less than the wall thickness of soft water pipe that is suitable for or tracheae 4.
