Abstract
This invention refers to a quick pipe joint, which contains joint unit and plug. Said invention features said joint unit having taper flange in outer wall of inner end, said plug having ellipse shape spring hook ring in outer wall of inner end, the ellipse shape spring hook ring having spring barb, when plug inserts in joint unit, the ellipse shape spring tying in the taper flange of joint unit to form joint. Said invention has simple structure, low cost, easy mounting and dismounting.
Description
Technical field:
The present invention relates to a kind of pipe joint, be specifically related to a kind of vehicle nylon pipe air braking system quick coupling.The link technical field that belongs to pipe part.
Background technique:
At present automobile fuel feeding and braking system adopt extensively that price is low, the nylon tube of function admirable, to replace traditional metallic conduit.ZL03233818 discloses a kind of " rapid pipe joint of vehicle nylon pipe air braking system ", and it exists complex structure, the more high deficiency of processing cost.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of simple in structure, quick coupling that fabricating cost is lower is provided.
The object of the present invention is achieved like this: a kind of quick coupling, comprise fittings body and plug, and it is characterized in that: the inner outer wall of described fittings body is provided with the taper convex shoulder; The inner outer wall of described plug is provided with oval elasticity shackle, and internal face both sides, the minimum place of oval elasticity shackle external diameter are provided with resilient barb; Joint inserts fittings body, and the taper convex shoulder auger that the resilient barb of oval elasticity shackle catches on fittings body is end face directly.
The present invention is simple in structure, fabricating cost is low, and assembling, convenient disassembly are quick.
Description of drawings:
Fig. 1 is an invention quick coupling External view.
Fig. 2 is invention quick coupling STRUCTURE DECOMPOSITION figure.
Fig. 3 is an invention quick pipe connecting header structure erection drawing.
Fig. 4 is the I enlarged view of Fig. 3.
Embodiment:
Referring to Fig. 1, the present invention relates to a kind of quick coupling, form by nylon fittings body 1 and nylon plug 2 two-part.Plug 2 and fittings body 1 socket connection.
Referring to Fig. 2～3, described fittings body 1 inner outer wall is provided with taper convex shoulder 1.1; Described plug 2 inner outer wall are provided with oval elasticity shackle 3, and internal face both sides, the minimum place of oval elasticity shackle 3 external diameters are provided with resilient barb 3.1, and resilient barb 3.1 in the form of sheets; Joint 2 inserts fittings bodies 1, and taper convex shoulder 1.1 augers that the resilient barb 3.1 of oval elasticity shackle 3 catches on fittings body 1 are end face directly.
Set O RunddichtringO 4 with fittings body 1 cooperation place on described plug 2 outer wall.
Referring to Fig. 4, the hook bottom end of described resilient barb 3.1 is arranged to intilted inclined-plane 3.1.1, and corresponding, taper convex shoulder 1.1 augers with matching directly end face also are arranged to intilted inclined-plane 1.1.
Quick grafting working principle:
Fittings body 1 outer end and source of the gas are with being threaded, with plug 2 the inners to fittings body is inner when inserting, oval elasticity shackle 3 compresses its inboard resilient barb 3.1 and moves forward along upper conical convex shoulder 1.1 male cone (strobilus masculinus)s of fittings body on the plug, after resilient barb 3.1 surpasses the auger footpath of taper convex shoulder male cone (strobilus masculinus), resilient barb 3.1 is thrown off resilience with the taper convex shoulder, and this moment, resilient barb 3.1 just caught on directly end face of taper convex shoulder 1.1 augers.So just can guarantee that the plug that has the vehicle nylon pipe is difficult for extracting in fittings body.O RunddichtringO on the plug plays seal action, guarantees unlikely leakage under the automobile working pressure.
Quick dismantlement work principle: plug 2 be extracted in fittings body 1, two fingers are firmly held oval elasticity shackle 2.1 external diameter biggest places, at this moment, the auger of resilient barb 3.1 and taper convex shoulder 1.1 directly end face unclamps, resilient barb 3.1 is directly held the inclined-plane return along taper convex shoulder 1.1 augers, and the plug of band nylon tube just can be extracted in fittings body.
