Abstract

The utility model relates to a bracket with limit movable wing, which includes a fixed wing connected with a bracket seat and a moving wing slidingly hinged to the bracket seat; a channel with adjustable spacing is formed between the fixed wing and the moving wing; the bracket is characterized in that a guide groove is opened on the bracket seat; the moving wing is provided with a slider capable of sliding in the guide groove; the end of the guide groove is provided with a limit point; the limit point can restrict the moving wing to fall apart from the bracket seat. Upon ex-factory, the movable bracket can assembly the moving wing and the bracket seat, so as to prevent the moving wing from falling off in clinical operation and reduce the clinical risks. The bracket has more reasonable structure design, not only the channel spacing can be appropriately regulated to meet the need of replacement of arch wires of different models, but also the moving wing can be limited in the bracket seat and is not easy to fall off, so as to ensure safety and reliability in use.

Description

Be with spacing Support slot with movable wings

Technical field:

This utility model belongs to the medical apparatus field, particularly a kind of improvement of Support slot with movable wings of straightening of teeth.

Background technology:

Existing orthodontics bracket structure is the bracket seat that a bottom surface and the flank of tooth match, and the surface of bracket seat offers flat recess, and the bracket seating face that flat recess separates forms the protruding wing naturally, and the outside of the protruding wing offers the ligation groove, is convenient to ligation.During use, the bracket bottom surface is bonded on the tooth, one of each facing bonding is pacified an arch wire in the flat recess then, uses the structure of each malposed tooth of elastic force traction correcting of arch wire.The arrangement of malposed tooth is different, and is also random, often is difficult to arch wire is pacified in the bracket flat recess on each facing.This claimant is in the patent of first to file: 200620097467.3, Support slot with movable wings by name, its structure one disjunctor has the decide wing and slide pivot of bracket seat to be located at the moving wing on the bracket seat, decide the wing and the moving adjustable flat recess of interplane formation one spacing, utilization clinically facts have proved, the bracket seat of deciding wing disjunctor is as localized benchmark, and utilize the moving wing to regulate the spacing of flat recess, operation is simple in ligation, and along with the rectification degree, the arch wire of conveniently replaced different sizes, and need not to change the bracket seat, this is the maximum characteristics of Support slot with movable wings, opens clinical the popularization gradually at present.Along with going deep into of clinical application, the deficiency of Support slot with movable wings also highlights once more, and during as clinical manipulation, movable wing easily produces and comes off, and falls into esophagus because of carelessness, and consequence is difficult to imagination, how to improve this utility model object of study.

Summary of the invention:

The purpose of this utility model is that a kind of bracket seat of design is provided with the spacing Support slot with movable wings of being with that the moving wing of restriction breaks away from the bracket seat.

Technical solutions of the utility model are achieved in that a kind of spacing Support slot with movable wings of being with, comprise that a disjunctor has the decide wing and slide pivot of bracket seat to be located at the moving wing on the bracket seat, decide the wing and the moving adjustable conduit of interplane formation one spacing, it is characterized in that offering on the bracket seat guide groove, the moving wing is provided with a slide block that can slide in guide groove, the guide groove end is provided with a spacing point, and this spacing point can limit the moving wing and break away from the bracket seat.Movable bracket when dispatching from the factory, can will move the wing with the bracket seat is assembled together, move the wing when avoiding clinical manipulation and deviate from, reduce clinical risk.

The spacing point of described guide groove end falls folding for the materials processing of bracket seat disjunctor the time and blocks guide groove and form.When the processing of bracket seat, disjunctor cuts out spacing point, rolls over spacing point behind the moving wing of packing into and gets final product, and does not increase too much processing and assembly technology, can reach the purpose that the moving wing of restriction comes off.

This utility model more reasonable structural design, both having had the conduit spacing can suitably regulate, and satisfies needing of different model arch wire replacing, can be limited in the bracket seat with moving the wing again, and difficult drop-off is safe and reliable.

The specific embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, be with spacing Support slot with movable wings, comprise that a disjunctor has the decide wing 11 and slide pivot of bracket seat 1 to be located at the moving wing 2 on the bracket seat, bracket seat 1 and the moving wing 2 are made by steel material, decide the wing 11 middle parts and be provided with the chute 12 that can supply the moving wing 2 pins 21 to insert, conduit 4 spacings that scalable was moved the wing 2 and decided 11 formation of the wing when both cooperated; Move the wing 2 and decide the wing 11 opposing sides and have ligation groove hook 3.Offer a guide groove 13 among the figure on the bracket seat 1, the moving wing 2 is provided with a slide block 22 that can slide in guide groove 13, and guide groove 13 ends are provided with a spacing point 14, and this spacing point 14 can limit the moving wing 2 and break away from bracket seat 1.The spacing point 14 of guide groove 13 ends falls folding for the materials processing of bracket seat 1 disjunctor the time and blocks the guide groove mouth and form.As Fig. 3, during processing bracket seat 1, spacing point 14 goes out for open and flat, treat that the wing 2 is fitted into after, again it is fallen to roll over toward guide groove mouth place and gets final product, as shown in Figure 2.Because bracket seat 1 itself has cooperating of chute 12 and pin 21 with 2 on the moving wing, it is movable in the larger context that spacing point 14 can limit the moving wing 2, satisfies the regulatory demand of maximum conduit 4 groove widths.Pin 21 is in the moving wing 2 central authorities in this example.

With reference to Fig. 4, Fig. 5, Fig. 6 and Fig. 7, pin 21 is in the moving wing 2 both sides in this example, and it can be processed into equally is with spacing Support slot with movable wings, and its structural relation and last example are together.

Spacing except that above-mentioned conjoined structure, it is spacing also can to adopt secondary welding to form, and the spacing point that also is guide groove 13 ends is for directly forming in the solid welding of guide groove end.During assembling, behind the moving wing of in advance packing into, make the guide groove mouth narrow down, be out of shape or form protruding solder joint at guide groove mouth place's spot welding one solder joint to get final product.But with the disjunctor scheme of falling the folding is good, the non-oxidation rust staining.
