DETAILED DESCRIPTION
[0045] The relevant terms labial, lingual, mesial, distal, occlusal and gingival are the industry terms for orthodontic treatment. Taking a tooth in the upper jaw as an example, the surface of the tooth can be roughly divided into six surfaces. The surface of the tooth that occludes with the lower jaw is the occlusal surface; the surface of the tooth that connects with the gingival tissue is the gingival surface; the occlusal surface and the gingival surface are opposite, and the direction formed by the occlusal surface and the gingival surface is also called the gingival-occlusal direction. The surface of the tooth that faces the lip is the labial surface, and the surface of the tooth that faces the tongue is the lingual surface; the labial surface and the lingual surface are opposite, and the direction formed by the labial surface and the lingual surface is also called the labial-lingual direction. The two surfaces of the tooth that contact with the adjacent teeth are the mesial surface and the distal surface, respectively, which differ in distance from the middle part, and the direction formed by the two surfaces is also called the mesial-distal direction, or the mesial-distal direction.
[0046] First embodiment
[0047] Please refer to Figures 1 to 4 The self-ligating bracket 10 in the first embodiment includes a bracket body 100, a locking piece 200, a locking core 300 and a sleeve ring 400. The bracket body 100 is provided with an archwire slot 110 for placing an archwire, the archwire slot 110 extends through the bracket body 100 along the mesial-distal direction, and the opposite sides of the archwire slot 110 are a first working wing 120 and a second working wing 130. The locking piece 200 is slidably arranged on the second working wing 130. Specifically, the locking piece 200 can slide along the gingival-occlusal direction. In the first embodiment, opposite side edges of the locking piece 200 are formed with sliding rails 210, and the second working wing 130 is formed with sliding grooves 131 matched with the sliding rails 210, and the locking piece 200 can slide along the gingival-occlusal direction in the sliding grooves 131.
[0048] The bottom surface of the locking piece 200 is provided with a locking groove 220, the second working wing 130 is provided with a mounting hole 132, the sleeve ring 400 is at least partially or entirely accommodated in the mounting hole 132, and the sleeve ring 400 does not protrude into the locking groove 220 of the locking piece 200, and the sleeve ring 400 is perpendicular to the second working wing 130. The outer diameter of the sleeve ring 400 is matched or interference-fitted with the inner diameter of the mounting hole 132, so that the sleeve ring 400 can at most produce axial rotation relative to the second working wing 130. Specifically, in the first embodiment, the sleeve ring 400 is entirely accommodated in the mounting hole 132. Of course, in other embodiments, the sleeve ring 400 is not entirely accommodated in the mounting hole 132, but only partially accommodated in the mounting hole 132, and the other part protrudes from the mounting hole 132.
[0049] The lock cylinder 300 is in a columnar shape, one end of which is arranged in the sleeve 400, and the other end of which protrudes out of the sleeve 400 and is arranged in the locking groove 220 of the lock plate 200, and the lock cylinder 300 cooperates with the locking groove 220 to realize the opening and closing of the lock plate 200. For example, the lock cylinder 300 is a flexible column, and the lock cylinder 300 can be deflected or deformed, and the opening and closing of the lock plate 200 is realized by deflection or deformation of the lock cylinder 300.
[0050] The self-locking bracket 10 has at least the following advantages:
[0051] The mounting hole 132 is arranged on the second working wing 130, and the sleeve 400 is at least partially or entirely accommodated in the mounting hole 132 and does not protrude into the locking groove 220 of the lock plate 200, and one end of the columnar lock cylinder 300 is arranged in the sleeve 400, and the other end protrudes out of the sleeve 400 and is arranged in the locking groove 220 of the lock plate 200. That is, compared with the traditional scheme, the sleeve 400 is additionally arranged outside the lock cylinder 300, and the sum of the outer diameters of the sleeve 400 and the lock cylinder 300 is larger than the outer diameter of the lock cylinder 300 alone, so the mounting hole 132 corresponding to the sleeve 400 and the lock cylinder 300 in the present application can also be designed to be larger in size. Whether the mounting hole 132 is formed by injection molding or directly drilled, the difficulty of forming the mounting hole 132 on the second working wing 130 can be effectively reduced, thereby improving the production efficiency.
[0052] Further, in the case that the sleeve 400 is entirely accommodated in the mounting hole 132, the height of the sleeve 400 is less than or equal to the depth of the mounting hole 132. The top end of the sleeve 400 is lower than the top end of the side wall of the mounting hole 132 or is flush with the top end of the side wall of the mounting hole 132. In the case that the sleeve 400 is at least partially accommodated in the mounting hole 132, the bottom end of the sleeve 400 is located in the mounting hole 132, and the top end of the sleeve 400 protrudes out of the mounting hole 132. In this way, the position and height of the sleeve 400 relative to the mounting hole 132 are variously selectable, which reduces the assembly precision requirement and improves the production efficiency. In addition, the position and height of the sleeve 400 affect the height of the lock cylinder 300 exposed out of the sleeve 400 / second working wing 130, and further affect the elastic performance of the lock cylinder 300. For example, the greater the height of the lock cylinder 300 exposed out of the sleeve 400 / second working wing 130, the greater the elastic performance of the lock cylinder 300, and the more likely to be deformed, thereby the lock plate 200 is more smoothly opened and closed. The smaller the height of the lock cylinder 300 exposed out of the sleeve 400 / second working wing 130, the smaller the elastic performance of the lock cylinder 300, and the less likely to be deformed, and the greater the pushing force required for the opening and closing of the lock plate 200.
[0053] Further, in the embodiment, the collar 400 is a circular collar 400, and the collar 400 is a closed ring. In this way, the manufacturing difficulty can be reduced. Of course, in other embodiments, the collar 400 can also be a substantially circular collar 400, an elliptical collar 400, a substantially elliptical collar 400, or a square collar 400, etc., as long as it can be used to increase the size of the mounting hole 132. Alternatively, the cross section of the inner side wall of the collar 400 is circular, elliptical or square, and / or the cross section of the outer side wall of the collar 400 is circular, elliptical or square, which can meet the requirements. Further, notches can be formed on the side wall of the collar 400, or opening grooves extending in the axial direction can be formed on the side wall of the collar 400, so as to increase the elastic performance of the collar 400 and reduce the assembly difficulty.
[0054] Further, in the embodiment, the number of the lock core 300 is one, and the number of the locking groove 220 is one, and the locking groove 220 has a sliding protrusion 221. Specifically, the lock core 300 is a solid column, the locking groove 220 is an arc-shaped groove, the sliding protrusion 221 is located in the middle of the locking groove 220, and the sliding protrusion 221 is located on the side wall of the locking groove 220, and the opening and closing of the lock blade 200 is realized by the deflection or deformation of the lock core 300. For example, when the lock blade 200 is located at the closed position, one end of the lock core 300 is located at the end 222 of the arc-shaped groove away from the archwire groove; during the process of opening the lock blade 200, one end of the lock core 300 moves from the end 222 of the arc-shaped groove away from the archwire groove to the end 223 of the arc-shaped groove close to the archwire groove through the sliding protrusion 221, and the lock blade 200 is opened.
[0055] Of course, in other embodiments, the lock core 300 is a solid column, and the locking groove 220 includes a limiting portion and an offset portion offset relative to the limiting portion. When the lock blade 200 is located at the closed position, the lock core 300 is located at the limiting portion, and after the lock blade 200 is opened, the lock core 300 is located at the offset portion. Alternatively, the lock core 300 is a hollow column, and the lock core 300 is provided with a slit in the axial direction, and the locking groove includes a limiting portion and a pressing portion or the locking groove includes a first limiting portion, a pressing portion and a second limiting portion which are sequentially communicated, and the pressing portion forms a sliding protrusion.

Specifically, the lock cores 300 are arranged in parallel and are spaced apart, the locking groove 220 includes a first limiting portion 224, a pressing portion, and a second limiting portion 225, and the pressing portion forms the sliding protrusion 221. When the lock plate 200 is in the closed position, the two lock cores 300 are located in the first limiting portion 224. During the opening of the lock plate 200, the two lock cores 300 are pressed into the sliding protrusion 221 and are deformed. After passing through the sliding protrusion 221, the two lock cores 300 are reset and are located in the second limiting portion 225. The lock plate 200 is in the open position.
