Detailed description of the invention

Referring to figs. 1 through Fig. 4, orthodontics self-locking bracket is described further.

A kind of orthodontics self-locking bracket, comprise bracket matrix 1, described bracket matrix 1 is provided with tie wings 2 and arch wire groove 3, in described arch wire groove 3, be provided with a block piece 4, described block piece 4 is connected with bracket matrix 1 by flexible member 5, forms the passage connecting for arch wire between described arch wire groove 3 and block piece 4.

In the present embodiment, by flexible member 5 is set on arch wire groove 3, the block piece 4 being connected with the bottom of arch wire groove 3, described flexible member 5 can be Elastic plastic-rubber or return spring 51, owing to being arranged at inside, oral cavity, must have good hygienic conditions, and there are good corrosion resistance and stable chemical property, return spring 51 is hardware, has good stability in cavity, so be preferably return spring 51; Described return spring 51 is four, the projecting edge 42 being distributed in respectively on four angles of block piece 4 is connected with bracket matrix 1, utilize the compression of return spring 51 and the elastic performance of stretching return, block piece 4 is anchored on arch wire in the arch wire groove of bracket matrix 1, prevent that arch wire from sliding between arch wire groove 3, make in the stable arch wire groove as for bracket matrix 1 of arch wire.

Be compression shape by the original state of return spring 51, return spring 51 is arranged on the both sides of block piece 4 near tie wings 2, make arch wire groove 3, block piece 4 and return spring 51 form a passage connecting for arch wire, when use, in the time that arch wire need to be put into the arch wire groove 3 of bracket matrix 1, by instrument, block piece 4 is pulled outwardly, return spring 51 is moved to the direction that deviates from arch wire groove, make arch wire groove 3, block piece 4 and return spring 51 form a passage connecting for arch wire and increase, arch wire is penetrated wherein, in the time that arch wire passes completely through its passage, to be that the return spring 51 that compresses shape connects by original state due to block piece 4, utilize its characteristic to compress to one end, bottom surface of groove, the space that arch wire connects is reduced, and then make more fastening being placed in arch wire groove 3 of arch wire, need to dismantle and make when arch wire, by instrument, block piece 4 is pulled to the direction that deviates from arch wire groove, make return spring 51 tensile deformations, arch wire groove 3, block piece 4 and return spring 51 form the passage connecting for arch wire and increase, its arch wire is pulled out, then block piece 4 contacts with the arch wire groove 3 of bracket matrix 1 by return spring 51 self-returns, makes to install or change more convenient to operate when arch wire.

By being provided with groove 41 near bottom one side of arch wire groove 3 at block piece 4, the height of described groove 41 is less than the thickness of arch wire, the thickness of arch wire is the distance between the contact-making surface of block piece 4 and the bottom surface of bracket matrix 1, the width of groove 41 is close with the thickness of arch wire, arch wire is positioned in block piece 4 grooves 41 to contact with arch wire trench bottom surfaces, by the return thrust of return spring 51, prevent that arch wire from sliding between block piece 4 and arch wire groove, make more fastening being placed in arch wire groove 3 of arch wire; The length that the length of block piece 4 is longer than arch wire groove 3 is set, in tie wings 2, cover has a dead ring 6, in the time that arch wire is subject to the power on arch wire groove 3 ground dorsad, be longer than the protuberance of arch wire groove 3 by block piece 4, can anti-stop part 4 answer arch wire stressed and skid off outside bracket matrix 1, arch wire is placed in the arch wire groove of bracket matrix 1.

By adopting technique scheme, the relative prior art of the utility model is compared to be had: by be provided with the block piece 4 being connected with the bottom of return spring 51 and arch wire groove 3 on arch wire groove 3, utilize spring to have good compressibility and the property upheld, can keep a good tightening state, block piece 4 is fastened on arch wire in the arch wire groove of bracket matrix 1, prevent that arch wire from sliding between arch wire groove 3, make in the stable arch wire groove as for bracket matrix 1 of arch wire.
