[0019] In this specification, orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc., which are mentioned or may be mentioned, are defined relative to its structure, and they are relative concepts. Therefore, it is possible that they will change accordingly depending on their different positions and different usage states; thus, these or other orientation terms should not be construed as restrictive terms either.
[0020] In this specification, the singular forms "a", "the", and "said" are intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
[0021] In order to make the technical problems to be solved, technical solutions, and beneficial effects of this application clearer and more understandable, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the embodiments described herein are only used to explain this application and are not used to limit this application.
[0022] The present utility model provides a bracket for orthodontics, as shown in the attached Figures 1-5 figures, including a bracket body 1 and a bracket base 2. The bracket body 1 and the bracket base 2 are fixedly connected. A wire slot 3 is provided through the inside of the bracket body 1 and a through slot 4 is opened. The through slot 4 is perpendicular to the wire slot 3. A fixed support rod 5 is provided in the through slot 4. A crescent member 6 is fixedly connected to the bottom end of the through slot 4. The fixed support rod 5 is snap-connected to the crescent member 6. Fixed components 7 are provided on both sides of the fixed support rod 5.
[0023] As Figure 2 shown in the figures, a splicing hole 8 is provided at the snap-connection position of the crescent member 6 and the fixed support rod 5. The splicing hole 8 has the same diameter as the wire slot 3. A wire passes through the splicing hole 8 and the wire slot 3 and is connected to the bracket body 1. By internally connecting the wire, the situation of external components of the bracket scratching the oral cavity is eliminated.
[0024] As Figure 4 、 5 shown in the figures, two grooves 10 are opened at the top end of the crescent member 6. Two protrusions 11 that match the grooves 10 are fixedly connected to the bottom end of the fixed support rod 5. The provided grooves 10 and protrusions 11 provide an effective fixing effect for the fixed support rod 5. Two sliders 12 are fixedly connected to both sides of the two protrusions 11. Two sliding grooves 13 for the sliders 12 to slide are opened in both of the two grooves 10. The provided sliders 12 and sliding grooves 13 provide a good guiding effect for the fixed support rod 5.
[0025] As Figure 3As shown, the fixing assembly 7 includes a spring 7.1 fixedly connected to the inside of the bracket body 1 at one end, a push block 7.2 fixedly connected to the other end of the spring 7.1, slides 7.3 are provided on both sides of the push block 7.2, and a slide rail 7.4 for two slides 7.3 to slide is provided inside the bracket body 1, and a limiting column 7.5 is fixedly connected to one end of the push block 7.2 away from the spring 7.1, and a limiting hole for the two limiting columns 7.5 to be engaged is provided in the fixed support rod 5. The fixing assembly 7 avoids the risk of scratching the oral cavity by the external lock by fixing the arch wire inside the bracket body 1. The slide 7.3 and the slide rail 7 provide good guiding effect for the push block 7.2, and a toggle block 14 is fixedly connected above the two slides 7.3 at the top. The toggle block 14 is convenient for pushing the push block 7.2, which is convenient for the user to operate.
[0026] like Figure 1 As shown, the edges of the bracket body 1 and the bracket base 2 are all set to be smooth chamfered, which effectively prevents the edges of the bracket body 1 and the bracket base 2 from scratching the oral cavity.
[0027] Working principle: When the utility model is implemented, firstly, a plurality of bracket bases 2 are sequentially bonded to the tooth surface by adhesive. Under the guidance of the slide 7.3 and the slide rail 7.4, the two toggle blocks 14 are pushed and the two push blocks 7.2 are driven to move to both sides, and the springs 7.1 on both sides are deformed, and the fixed support rod 5 is placed in the through groove 4, and under the guidance of the slider 12 and the slide groove 13, the protrusion 11 is engaged with the groove 10, the two toggle blocks 14 are released and the spring 7.1 is restored to the initial state, and the two limit posts 7.5 are engaged with the limiting holes on the fixed support rod 5, and the arch wire is sequentially passed through the plurality of arch wire holes 3 and the plurality of splicing holes 8. Since the components and arch wires are all inside the bracket, and the edge parts of the bracket body 1 and the bracket base 2 are both smoothly chamfered, scratching the inner wall of the oral cavity is prevented.
[0028] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
