Abstract
The invention discloses a correcting bracket which comprises a bracket body and a bracket cover, wherein a kidney hole is formed in a working wing of the bracket body, and a convex platform is horizontally extended on a bracket body on the left side of an arch wire trough to a direction deviating from the arch wire trough; the bracket cover is composed of a cross edge and vertical edges extending from two ends of the cross edge to the side direction of the cross edge, and shaft holes are formed in the bottom surfaces of the vertical edges of the bracket cover; the width of the bracket body is smaller than that of the bracket cover, and the bracket body is arranged between the two vertical edges of the bracket cover; pin shafts penetrate the kidney holes and the shaft holes; a bent hook is arranged on the bottom surface of the cross edge of the bracket cover and is formed in the way that the margin of the cross edge of the bracket cover is bent down and then is bent in the direction of the shaft holes, and a hook groove is formed in the bent hook; the cross edge of the bracket cover is covered on the convex platform of the left side of the arch wire trough, and the bent hook is matched with the convex platform. The bracket body and the bracket cover are simply manufactured, can adopt wire cutting for one-step forming, and are conveniently operated. Meanwhile, the width of the bracket body is smaller than that of the bracket cover, so that the size of the bracket body is smaller.
Description
Technical field
The present invention relates to the orthodontic technical field, particularly a kind of orthodontic bracket.
Background technology
At present, in the orthodontic treatment process of Buccodental, orthodontic bracket is fixed on facing, arch wire is through the archwire slot (having another name called square shred groove) on bracket, and by ligation rubber ring or steel ligature by the direct ligation of arch wire in the bracket archwire slot, the corrective force of arch wire is delivered to tooth by bracket, makes tooth produce the movement of expecting, to reach the purpose of proofreading and correct tooth.
On the tie wings of bracket, directly force in arch wire due to ligation rubber ring at present used or steel ligature ligation, arch wire has been produced to larger pressure, hindered the normal movement of arch wire, thereby shadow is to the correction effect of tooth.At present, also occurred multiple locking bracket on market, the large series of active and passive type two has been arranged, but structure more complicated all, manufacture difficulty is large, and cost is high, expensive, operating difficulties.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of easily manufactured, simple to operate, reliable and stable tooth bracket is provided.
Technical scheme of the present invention is achieved in that
A kind of orthodontic bracket, comprise and covering the supporter groove with arch wire groove and the bracket coordinated with supporter groove, the right side of arch wire groove is provided with working wing, offer slot on the working wing on arch wire groove right side, on the supporter groove in arch wire groove left side, towards the direction horizontal-extending that deviates from the arch wire groove, boss is arranged; Bracket lid overall U-shaped, by horizontal edge and by the horizontal edge two ends, the vertical edge to the stretching, extension of horizontal edge side forms the bracket lid, be provided with axis hole on the flange of bracket lid vertical edge bottom surface, the width of supporter groove is less than the width of bracket lid, and supporter groove is arranged on bracket and covers between two vertical edges, be equipped with bearing pin in slot, bearing pin is located in the axis hole on two vertical edges of bracket lid simultaneously; Be provided with crotch on the bottom surface of bracket lid horizontal edge, described crotch is to the axis hole direction, to be bent to form downwards by the edge of bracket lid horizontal edge is first again, form the hook groove in crotch, the horizontal edge of bracket lid covers on the boss in arch wire groove left side, and crotch matches with boss;
When promoting the bracket lid to the right, the right-hand member of bearing pin in slot, the boss in arch wire groove left side snaps in the hook groove of crotch, and now crotch is spacing by boss backstop, and bracket covers in the closed-lock state;
When promoting the bracket lid left, bearing pin enters the left end of slot, and the hook groove of crotch breaks away from boss, and crotch is no longer by boss backstop, and the bracket lid can be opened around the bearing pin upset, just exposes the arch wire groove, can put into or take out arch wire, and now the bracket lid is open mode.
For the bracket lid is not opened easily, as preferably, be provided with at least one at the middle part of slot bearing pin is carried out to spacing projection.Convex shape can be arc, and being arranged on when the bracket lid slides of projection increased resistance, prevents that the situation that is free to slide and opens from use appearring in the bracket lid.
For making integral body more attractive in appearance, as preferably, the upper surface of arch wire groove left side boss is lower than the upper surface of arch wire groove right side working wing, difference in height between the upper surface of arch wire groove left side boss and the upper surface of arch wire groove right side working wing equals the thickness of bracket lid, when the horizontal edge of bracket lid covers on the boss in arch wire groove left side, the end face of bracket lid and the upper surface flush of arch wire groove right side working wing.Like this, when bracket covers in the closed-lock state, the end face of supporter groove and bracket lid is on same plane, very attractive in appearance, easy to clean.
Adopted design philosophy of the present invention and the beneficial effect of technique scheme to be:
The present invention adopts and renovates the slide lock tabs structure, the vertical edge of bracket lid normally slides in the supporter groove both sides, be provided with slot and bearing pin on the working wing on arch wire groove right side, on the supporter groove in arch wire groove left side, level is provided with boss, the vertical edge of bracket lid is provided with the axis hole coordinated with bearing pin, formed the crotch that boss coordinates on bracket lid horizontal edge, bearing pin is located in axis hole and slot all the time and bearing pin is fixed with respect to the bracket lid, but along with sliding in the front and back of bracket lid, can make the diverse location of bearing pin in slot, and boss can snap in or break away from crotch along with the movement of bracket lid, thereby make the bracket lid in closure or open mode.
Supporter groove of the present invention and bracket lid are made simple, can adopt line cutting once-forming, easy to operate.The supporter groove width is less than the width of bracket lid simultaneously, makes the bracket volume less.When bracket covers on supporter groove, the upper surface of bracket lid or the upper surface of end face and supporter groove, on same plane, have not only covered arch wire, also make very attractive in appearance while using, clean generous; Removed the troublesome operation of steel ligature in clinical practice from.Can as steel ligature or ligation rubber ring, directly not force in arch wire again, therefore can not affect the normal movement of arch wire in the orthodontic treatment process, make the orthodontic treatment better effects if simultaneously.
Because the part bracket has certain axial rake, supporter groove of the present invention and bracket lid will have certain gradient, and bracket covers while opening, and the bracket lid had both rotated around bearing pin; Bracket covers slot when being pushed simultaneously also has relative sliding with bearing pin; Because the present invention adopts the slot structure, and slot is open state, makes function of the present invention and purpose easily be achieved.
