Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
For the self-locking orthodontic bracket of orthodontics in the present invention, the substrate 1 comprising arc shape and the bracket body 2 be attached thereto.The cambered surface surface of substrate 1 arranges staggered rill, and bracket body 2 is provided with main archwire slot 3, and the direction of main archwire slot 3 is mutually vertical with the axis of substrate 1 cambered surface.Bracket body 2 is square, and its upper end is divided into two parts by through main archwire slot 3, is respectively equipped with cover plate insert port 4 and cover plate locking mouth 5; Have the cover plate 6 of a niti material in " mountain " font, its protuberance 7 is three parallel rectangles, and the tip inside of the protuberance on its both sides is provided with horn shape position 8 relatively, and middle protuberance then has downward concave shape; The length of three protuberances 7 of cover plate 6 is identical.For adapting with the shape of cover plate 6, described cover plate insert port 4 has through interstitial hole and is positioned at the pass through openings of interstitial hole both sides, and is provided with the recessed position corresponding with horn shape position, cover plate 6 end 8 in the inside of two pass through openings; For adapting with the shape of cover plate 6, described cover plate locking mouth 5 has the interstitial hole corresponding with cover plate insert port 4 and two side openings; And the recessed position corresponding with horn shape position, cover plate 6 end 8 is provided with in the inside of two side openings.Interstitial hole and two side openings of cover plate locking mouth 6 are non-penetrating.
After assembling, cover plate 6 inserts cover plate insert port 4.Owing to being equipped with the recessed position corresponding with horn shape position, cover plate 6 end 8 at the both-side opening of cover plate locking mouth 5 and cover plate insert port 4, therefore cover plate 6 can realize spacing in these two positions.That is: when horn shape position 8 is arranged in the recessed position of cover plate locking mouth 6, cover plate 6 is in lock-out state, and main archwire slot 3 is closed by cover plate 6; When horn shape position 8 is arranged in the recessed position of cover plate insert port 4, cover plate 6 is in released state, and main archwire slot 3 is unlimited.
Because cover plate only exposes very little area after inserting cover plate locking mouth 6 completely, conveniently take out, be provided with through hole at the middle part of the connecting portion of the protuberance 7 of cover plate 6.Like this, can use the conventional small tool with tip or crotch that cover plate 6 just can be allowed to realize switching in locking or released state, to facilitate, thin arch wire or dental arch filament be loaded in main archwire slot 3.
