Chinese patent discloses a kind of " locking quick coupled filter element " for No. 200420091797.2, its major technique feature is that filter tube two ends and quick coupled angle fitting junction are provided with the hole, have a locking plate to penetrate and just be stuck in the hole between the two circle convex tendons of quick elbow, locking plate is " crab claw " shape of circular arc.The assembling of this kind fast-connection filter element needs two steps, and the one, quick coupled angle fitting is inserted the inlet opening or the apopore of filter tube end, the 2nd, described locking plate is stuck between the two circle convex tendons of quick elbow.Therefore its assembly manipulation still comparatively bothers.In addition, this locking plate also comes off from convex tendon easily, causes the junction loosening.
The utility model content
The utility model provides a kind of fast-connecting type filter core, and its main purpose is to overcome existing filter core interface assembling and comparatively bothers, connects unsettled shortcoming.
The utility model adopts following technical scheme: the fast-connecting type filter core, comprise a filter core main body and an end cap, and this filter core body end is provided with the inlet opening, connects as one by revolving molten mode around this end cap and this filter core body end inlet opening; This inlet opening forms little stepped of outer imperial palace, and this end cap middle part is provided with a through hole, and the diameter of this through hole is less than the diameter of the big portion in this inlet opening; Be coated with a locating ring for external water pipe insertion location in the through hole of this end cap, the inner end of this locating ring is buckled in the inboard periphery of this end cap through hole by some barb-shaped claws; Be provided with a sealing ring that can be clamped between the big portion of external water pipe periphery wall and this inlet opening perisporium that inserts the inlet opening in the big portion in this inlet opening.
Aforementioned fast-connecting type filter core, its filter core main body forms an annular fitting recess on every side in this inlet opening, the opposite face of this end cap and this filter core body end be provided with one with the suitable mounting ring of this annular fitting recess, this mounting ring and this annular fitting recess are connected by revolving the mode of melting; The cross section of described mounting ring and this annular fitting recess is a triangle.
Aforementioned fast-connecting type filter core, its end cap is provided with the bulge loop that convexedly stretches in the described inlet opening, this bulge loop inboard also is provided with a hold-down ring, and the bulge loop inner end butt of the outer end of this hold-down ring and end cap, the inner end of this hold-down ring are pressed in described sealing ring the bottom of the big portion in described inlet opening.
Aforementioned fast-connecting type filter core, its end cap outer peripheral face along the circumferential direction is evenly distributed with three locating slots that are used to revolve process of smelting.
Aforementioned fast-connecting type filter core, each claw inboard of its locating ring are embedded with external water pipe are clamped in therebetween sheet metal.
By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art: one, during assembling, only need external water pipe inserted from its end cap locating ring middle part and get final product, operation is very easy, can one goes on foot to finish; Two, after external water pipe inserts, with each claw to around strut, the while sheet metal of each claw inboard is clamped in external water pipe therebetween, and it can't outwards be slided, its structure is highly stable and reliable; Three, adopt and revolve process of smelting, be particularly suitable for the nonpoisonous and tasteless PP polypropylene material that present filter core extensively adopts.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the cutaway view of decomposing state of the present utility model.
The specific embodiment
Below with reference to Fig. 1 and Fig. 2 the specific embodiment of the present utility model is described.
See figures.1.and.2, this fast-connecting type filter core comprises a filter core main body 1 and an end cap 4, and this filter core main body 1 end is provided with inlet opening 10, and this end cap 4 connects as one by revolving molten mode on every side with this inlet opening, filter core main body 1 end 10.This inlet opening 10 forms little stepped of outer imperial palace, and these end cap 4 middle parts are provided with a through hole 40, and the diameter of this through hole 40 is less than this inlet opening diameter of portion 101 greatly.Be coated with a locating ring 5 for external water pipe insertion location in the through hole 40 of this end cap 4, the inner end of this locating ring 5 is buckled in the inboard periphery of these end cap 4 through holes 40 by four barb-shaped claws 51.And each claw 51 inboard of this locating ring 5 are embedded with external water pipe are clamped in therebetween sheet metal 52, and each sheet metal 52 slopes inwardly.Be provided with a sealing ring 2 that can be clamped between the big portion of external water pipe periphery wall and this inlet opening 101 perisporiums that insert inlet opening 10 in the big portion 101 in this inlet opening.In the drawings, owing to dissect, claw 51 only can be seen three.
This filter core main body 1 forms an annular fitting recess 11 around this inlet opening 10, the opposite face of this end cap 4 and this filter core main body 1 end be provided with one with the suitable mounting ring 41 of this annular fitting recess 11, this mounting ring 41 is connected by revolving the mode of melting with this annular fitting recess 11.And mounting ring 41 is a triangle with the cross section of this annular fitting recess 11.End cap 4 outer peripheral faces along the circumferential direction are evenly distributed with three locating slots 43 that are used to revolve process of smelting.Owing to dissect, only show a locating slot 43 among the figure.Revolving process of smelting is maturation process, no longer describes at this.
