For the shoe buckle of flip-flop dual-purpose shoe
Technical field
The present invention is a kind of shoe buckle, is for the shoe buckle after flip-flop dual-purpose shoe on shoestring specifically.
Technical background
The shoe buckle of shoestring only has the effect of fixed shoestring and decoration after flip-flop dual-purpose shoe at present, and can do turning for circle
It is dynamic.Thereafter shoestring is when wearing, often because shoestring cuts out too long or stress is elongated or summer when being filled with
Heat expansion causes shoestring pine length and the situation that shoestring downslide cannot clasp heel occurs, is even connected with elastic band, still unavoidably
It pitches downslide.After situation as appearance, footwear as dress can only be worn with regard to very inconvenient when slippers, and cannot work as sandals
It wears.
The content of the invention
The present invention is in order to glide and cannot clasp heel after solving the pine excessively of above-mentioned shoestring existing for current flip-flop dual-purpose shoe
Deficiency, provide and a kind of remain able to clasp the shoe buckle of heel in the case of rear shoestring excessively pine.
The first technical solution is:A kind of shoe buckle for flip-flop dual-purpose shoe is made of internal buckle and outward buckle;Outward buckle is by detaining
Lid, button bottom and button cylinder composition, buckle closure is the metal component for having frame, and the one side both sides with detaining bottom split are fan-shaped protrusions, intermediate
Scalloped recess, it is each there are one hook footwear piece at the sector protrusion of both sides, button bottom and detain cylinder be a disjunctor among perforation plastic part,
Button bottom on have with the corresponding hole of buckle closure hook footwear piece, detain cylinder in bottom be lock buckling groove, there is square hole in side;The end of internal buckle button cylinder
End is convex with the corresponding lock of the lock buckling groove of outward buckle, and bottom surface is square groove, and there is hook footwear piece at button bottom;It is set between internal buckle and outward buckle
Zigzag spring wire is equipped with, one is long and the other is short at spring wire both ends, and longer one end is buckled in the scalloped recess of outward buckle, and shorter one end is linked closely
In the square groove of internal buckle.
Outward buckle buckle closure and the both sides for detaining bottom phase split, the fan-shaped protrusion and scalloped recess of buckle closure can be arranged on button bottom
On.
The opening angle of scalloped recess is generally between 70 ° -130 °.
The square hole of outward buckle button cylinder side is used to determine when installing shoe buckle the position of spring wire, facilitates installation, therefore, can be with
It is arranged to circular and other shapes.
Spring wire is first mounted in outward buckle button cylinder, buckle closure is buckled, presses frame;Internal buckle and outward buckle are tightly locked in footwear respectively
On mouth and rear shoestring, hook footwear piece is compressed;Internal buckle square groove is inserted into spring wire one end, outward buckle in locking, shoe buckle just installs.
Afterwards the opening amplitude of shoestring and welt can by adjust the setting angle of outward buckle and the angle at spring wire both ends come
Control.It is mounted after shoestring under the action of spring wire with regard to a suitable position can be maintained at, in addition, it is desirable to when, energy
The position of welt is enough rotated it to, i.e., can make sandals but also is worn as slippers.
Second of technical solution be:A kind of shoe buckle for flip-flop dual-purpose shoe is made of internal buckle and outward buckle;Outward buckle is by detaining
Lid, button bottom and button cylinder composition, buckle closure are the metal component for having frame, and respectively there are one hook footwear piece, button bottom and button cylinder are a companies on both sides
Body among perforation plastic part, detain bottom on have with the corresponding hole of buckle closure hook footwear piece, detain bottom among be semicircle orifice, detain cylinder in
Bottom is lock buckling groove;Internal buckle button cylinder have with the lock buckling groove of outward buckle it is corresponding lock it is convex, end be in detain bottom semicircle orifice in
Fan-shaped convex, there is hook footwear piece at button bottom.
The sector inside buckled is convex and button bottom that is buckling outside is the component in the same center of circle, when outward buckle turns along internal buckle button cylinder
It is dynamic, when the straight flange of semicircle orifice arrives to fan-shaped convex edge, by it is fan-shaped it is convex prop up without being rotated further by, shoestring and welt after thus controlling
Appropriate position is kept, is unlikely to that rear shoestring is allowed to slide and buckles incessantly heel.
The effect of hook footwear piece is shoestring and welt after fixing, and so as not to arbitrarily be rotated on shoe buckle button cylinder, therefore, is set
The quantity put is buckled in internal buckle and outside either respective one or 2-3.
The beneficial effects of the invention are as follows:It 1st, will not under the action of spring wire or sector are convex with the rear shoestring that this shoe buckle fastens
It glides because of loose length, rear shoelace buckle is caused not live the situation of heel.2nd, this shoe buckle when mounted, after adjusting as needed
The opening amplitude of shoestring and welt.
