[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The sliding sheet type self-ligating bracket as shown in fig. 1-6 comprises a bracket body 1, wherein an arch wire groove 2 is concavely formed in the middle of the bracket body 1, a sliding groove 3 is concavely formed on one side of the top of the bracket body 1, and a limiting groove 4 is concavely formed on the other side; the two sides of the sliding chute 3 are provided with sliding ways 4, the middle part of the sliding chute 3 is provided with a guide groove 5, the two sides of the guide groove 5 are provided with mounting holes 6, and the mounting holes 6 are internally provided with elastic pieces; the chute 3 is connected with a T-shaped locking plate 17 in a sliding way; the locking plate 17 is convexly provided with a guide convex strip 7 matched with the guide groove 5; the bottom of the locking plate 17 is concavely provided with a locking groove 8 matched with the elastic piece, the locking groove 8 comprises positioning grooves 9 at two ends, and convex sliding salient points 10 and sliding channels 13 are formed between the positioning grooves 9.

The bottom surface of the inner end of the locking plate 17 is concavely provided with a limiting part 11 matched with the limiting groove 4 and a step 18 matched with the arch wire groove 2, and the thickness of the step 18 is 0.01-0.8 mm; the depth of the arch wire groove 2 is 0.3-0.8 mm.

The middle part of the locking groove 8 is formed with a reinforcing rib 12, two sides of the reinforcing rib 12 are respectively provided with a locking groove 8, and the guide convex strip 7 is arranged on the reinforcing rib 12.

The sliding salient points 10 are integrally formed with the reinforcing ribs 12, and the positioning grooves 9 are positioned inside the sliding channels 13.

Working wings 14 are convexly formed at four corners of the bracket body 1, and ligation grooves 15 are concavely formed on the bottom surfaces of the working wings 14.

The corners of the working wings 14 are rounded.

The elastic part is a nickel-titanium tube, a nickel-titanium wire or a stainless steel wire. An auxiliary square thread hole 16 is formed on the bracket body 1. The sliding protrusion 10 has a trapezoidal shape. The cross sections of the guide grooves 5 and the guide convex strips 7 are arc-shaped.

The structure is used as follows:

the self-ligating bracket is adhered to the tooth, wherein the self-ligating bracket adhered to the upper jaw slides the locking plate 17 downwards or upwards to open the archwire slot 2, and the self-ligating bracket adhered to the lower jaw also slides the locking plate 17 downwards or upwards to open the archwire slot 2. When the locking plate 17 is opened, the elastic piece is extruded through the sliding salient points 10 when the locking plate 17 slides, so that the elastic piece is bent to enter the sliding channel 13, then the locking plate 17 continues to slide, so that the elastic piece enters the positioning groove 9 on the inner side to complete the positioning when the locking plate is opened, then the arch wire is placed in the arch wire groove 2, and then the locking plate 17 is slid to cover the arch wire groove 2. Wherein, because the step 18 of the locking plate 17 has thickness, the depth (the height of the square wire groove) of 7mm is formed after being combined with one side of the arch wire groove 2, thereby reducing the whole thickness of the self-ligating bracket and reducing the influence on the mouth tactility. And the guide groove 5 effectively prevents the locking caused by skew when the locking piece 17 slides. In addition, the strengthening rib 12 has guaranteed the intensity of locking plate 17 to form the structure that constant head tank 9 is in slide channel 13 is inboard, all to the outside bending when making the elastic component crooked, thereby can not consider the interference of elastic component, reduce the width of self-ligating bracket, thereby further reduce the whole volume of self-ligating bracket. The ligation groove 15 is convenient for positioning the wire during winding, and prevents the loosening caused by inaccurate winding. For ligation guidance, the structure provides a chamfered bevel 19 at the bottom of the outer end of the working wing 14.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the utility model in any way, and any simple modification, equivalent change and modification made by those skilled in the art according to the technical spirit of the present invention without departing from the technical scope of the present invention are all within the scope of the present invention.
