Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-5:
A kind of pipe joint structure, comprise left fittings body 1 and right connector body 2, left fittings body 1 and right connector body 2 are body, the inner of described left fittings body 1 is provided with wing seat 13, the quantity that all sides of wing seat 13 are provided with three above flank 132(flanks is determined by the caliber of left fittings body 1 and right connector body 2, caliber more flank is more), the inner end of described right connector body 2 is provided with the clamping seat 21 of inserting for the wing seat 13 of left fittings body, on clamping seat 21, be provided with identical with described flank 132 numbers, and the caulking groove 211 embedding for flank 13; One side of described caulking groove 211 bottoms is provided with the guide groove 213 that screws in and clamp for described flank 132.
When flank 132 screws in draw-in groove, left fittings body 1 and right connector body 2 are all along moving (both are near each other) in body axial direction.
When left fittings body 1 and right connector body 2 dock, first flank 13 is aimed to caulking groove 211, again wing seat 13 is inserted to clamping seat 21, now, left fittings body 1 is rotated relative to right connector body 2, make flank 13 screw in guide groove 213 and clamping, complete the connection of left fittings body 1 and right connector body 2, it is simple to operate, safe and reliable, good sealing effect.
Preferably, on the inwall of described wing seat 13, be provided with slope 135 or step (the present embodiment is slope); In described clamping seat 21, be provided with water stop ring 214, the outer wall of water stop ring 214 is provided with the projection 2141 coordinating with the inner wall sealing of described wing seat 13.When left fittings body 1 is connected with right connector body 2 (, flank 132 screws in and is clamped in corresponding guide groove 213), projection 2141 on water stop ring 214 outer walls is pushed against the inwall of wing seat 13, interference fit by both realizes sealing, because the inwall of wing seat 13 is slope, it is tightr that water stop ring 214 screws in more sealing.
Preferably, the bore of described left fittings body inner 15 and right connector body the inner 24 is all less than the bore of outer end separately, and this design makes current when leaving this pipe joint structure, causes extra pressure can to water stop ring 214 and the fitting surface of wing seat 13.
Preferably, all sides of described wing seat 13 the inners are provided with annular groove 131, are provided with seal ring 3 in annular groove 131.When left fittings body 1 and right connector body 2 coordinate, seal ring 3 is close to clamping seat 21 inwalls, and the anchor ring of wing seat 13 the inners is pushed against on clamping seat 21.Under normal circumstances, by the interference fit between water stop ring 214 outer walls and wing seat 13 inwalls, just can realize sealing, sealing circle 3 and annular groove 131 are optional designs of further leakproof, when the hydraulic pressure in left and right fittings body is too high conventionally, use.
Preferably, all sides of described left and right fittings body outer end all form baffle ring 11,22, and the periphery of baffle ring 11,22 is the conical surface.
Preferably, on the outer wall at described left and right fittings body middle part, form the anti-skidding convex tendon 12,23 in some roads.
Preferably, the thickness of the screw terminal 1322 of described flank 132 is less than the thickness of tail end 1321, the outer imperial palace of width of described guide groove 213 is little (specifically, the width of one end being communicated with caulking groove 211 of guide groove 213 is greater than the width away from one end of caulking groove), this design makes flank 132 more easily screw in guide groove 213 clamping.
Preferably, the outer rim of described wing seat 13 the inners is provided with chamfering 134.
Preferably, described flank 132 is three, is distributed on 13 weeks sides of described wing seat; Described caulking groove 211 correspondences are provided with three.
Preferably, anti-slip veins 212 can be set on the outer wall of clamping seat 21, be convenient to connect or separate left and right fittings body.
As preferably, can on the cell wall of guide groove 213, be provided with and stop the projection that the flank 132 screwing in guide groove 213 exits (position of projection can be arranged on many places, only need just can block the tail end of the flank of screw-in), when needs separate left and right fittings body, need by larger power, the hindered side who makes the tail end of flank overcome projection can exit guide groove.
Be pointed out that, wing seat 13 is for the installation position of flank 132 is provided, if the thickness of left and right fittings body is less, the inner thickening of left fittings body need to be formed to wing seat 13, to prevent flank fracture of root; If when the thickness of left and right fittings body is larger, wing toilet is without thickening, thereby causes wing seat visual invisible.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
