[0029] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0030] The following is combined with Figure 1-Figure 7 This embodiment is described in further detail.

[0031] See also Figures 1-6 In this embodiment, an orthodontic nickel-titanium square wire bracket includes a bracket body 100. An archwire slot 200 for mounting a square wire arch 120 is opened in the bracket body 100 along its width direction. The bracket body 100 is provided with an upper cover mounting slot 210 connected to the archwire slot 200 along its length direction. An upper cover 130 is slidably provided in the upper cover mounting slot 210. Slide grooves 211 are provided on the opposite side walls of the upper cover mounting slot 210 along its length direction. Sliders 400 sliding in the corresponding slide grooves 211 are provided on both sides of the upper cover 130. A first fixing member for fixing the upper cover 130 is provided in the upper cover mounting slot 210. A second fixing member for fixing the upper cover 130 is also provided in the bracket body 100.

[0032] In this embodiment, the lower side of the bracket body 100 extends outward to form a base plate 110, which is adhered to the surface of the teeth of the person to be corrected by an adhesive, thereby achieving the fixation of the bracket body 100 on the teeth. The archwire 120 is installed in the archwire slot 200, thereby allowing the archwire 120 to apply force to the bracket body 100, that is, the archwire 120 applies force to the teeth, so that the teeth are moved to the correct position, that is, the bracket can correct the teeth;

[0033] In actual use, the bracket body 100 of this embodiment is made of nickel-titanium alloy, which has the advantages of good biocompatibility, is not likely to cause damage to teeth, and has moderate hardness, which can provide a good wearing experience;

[0034] The upper cover 130 is slidably mounted in the upper cover mounting groove 210, thereby blocking the upper end opening of the archwire slot 200. This allows the square arch 120 to be positioned in the archwire slot 200, thereby preventing the square arch 120 from falling out of the archwire slot 200 and affecting tooth correction.

[0035] The arrangement of the slide groove 211 and the slider 400 allows the slider 400 to slide in the slide groove 211, allowing the upper cover 130 to slide into the upper cover mounting groove 210, so that the upper cover 130 is limited in the upper and lower directions in the upper cover mounting groove 210. This, in conjunction with the arrangement of the first fixing member, can better achieve the fixing of the upper cover 130 in the upper cover mounting groove 210.

[0036] The first fixing member and the second fixing member are provided so that the upper cover 130 can be fixed multiple times. Even if the first fixing member fails, the second fixing member can fix the upper cover 130 without causing the upper cover 130 to separate from the upper cover mounting groove 210 and causing the square wire arch 120 to separate from the archwire slot 200. Conversely, when the second fixing member fails, the first fixing member can fix the upper cover 130 without causing the upper cover 130 to separate from the upper cover mounting groove 210, thereby achieving a better fixation effect of the square wire arch 120 in the archwire slot 200.

[0037] During actual use of this embodiment, the top surface of the upper cover 130 is flush with the top surface of the bracket body 100. At the same time, the top surface of the upper cover 130 is smoothly arranged, so that when the bracket is installed on the teeth, there is no foreign body sensation when its outer end surface contacts the oral cavity, thereby improving its comfort.

[0038] like Figure 1-5As shown, in this embodiment, the first fixing member includes a mounting hole relatively arranged at the bottom end of the upper cover mounting groove 210, a first elastic member 212 is provided in the mounting hole, a fixing hole 500 is provided relatively on a side wall of the upper cover 130 close to the mounting hole, and a notch groove 510 is provided on one side of the upper cover 130 close to the first elastic member 212 along its width direction, and the upper end portion of the first elastic member 212 can slide along the notch groove 510 and extend into the corresponding fixing hole 500.

[0039] In this embodiment, due to the provision of the notch groove 510, an inclined surface is formed on one end of the upper cover 130. When the upper cover 130 slides along the upper cover mounting groove 210, the first elastic member 212 is squeezed by the inclined surface, and the first elastic member 212 moves downward until the fixing hole 500 is aligned with the first elastic member 212. The first elastic member 212 can extend into the corresponding fixing hole 500, thereby fixing the upper cover 130 in the height direction within the upper cover mounting groove 210. The coordinated provision of the slide groove 211 and the slider 400 can better achieve the fixation of the upper cover 130 in the upper cover mounting groove 210.

[0040] The number of the first elastic member 212 and the number of the fixing holes 500 are both two. This structure makes the fixing effect of the first elastic member 212 on the upper cover 130 more stable.

[0041] In actual use, the first elastic member 212 is made of existing silicone material, so that it has a certain deformation ability.

[0042] like Figure 1-7 As shown, in this embodiment, a first mounting groove 213 is provided on the side wall opposite to the upper cover mounting groove 210 along its width direction, a second mounting groove 410 is provided in the upper cover 130 along its width direction corresponding to the first mounting groove 213, the second mounting groove 410 is arranged through the upper cover 130, and a first fixing groove 700 and a second fixing groove are provided opposite to each other in the first mounting groove 213. A fixing pin 600 for fixing the upper cover 130 is also provided in the first mounting groove 213, and a second elastic member 610 that can slide along the first fixing groove 700 and the second fixing groove is provided on the side wall of the fixing pin 600.

[0043] In this embodiment, when the upper cover 130 is inserted into the upper cover mounting groove 210, the fixing pin 600 is passed through the upper cover 130 via the first mounting groove 213 and the second mounting groove 410, so that both ends of the fixing pin 600 are placed in the bracket body 100. Through this structure, the upper cover 130 is further fixed in the upper cover mounting groove 210;

[0044] In the process of the fixing pin 600 extending into the first mounting groove 213, an inclined surface is formed at the edge of the first fixing groove 700 and the second fixing groove, and the second elastic member 610 can shrink along the inclined surface of the first fixing groove 700 toward the direction close to the fixing pin 600. When the second elastic member 610 extends into the second fixing groove, the second elastic member 610 will collide in the direction away from the fixing pin 600 and get stuck in the edge of the second fixing groove. At this time, the fixing pin 600 will not detach from the opening of the second mounting groove 410, that is, the fixing pin 600 is further fixed to the upper cover 130 located in the upper cover mounting groove 210, thereby improving the fixation of the upper cover 130 in the upper cover mounting groove 210.

[0045] like Figure 1-2 As shown, in this embodiment, the cross section of the archwire slot 200 is T-shaped, and the square wire arch 120 includes a horizontal archwire portion 120a and a vertical archwire portion 120b.

[0046] In this embodiment, the T-shaped structure of the archwire slot 200 cooperates with the horizontal archwire portion 120a and the vertical archwire portion 120b, so that the square arch 120 is fixed in the archwire slot 200, preventing the square arch 120 from rotating in the archwire slot 200, making the fixation of the square arch 120 in the archwire slot 200 more stable.

[0047] Working principle: First, place the square wire arch 120 in the archwire slot 200, then slide the upper cover 130 into the upper cover mounting slot 210. When the upper cover 130 slides along the upper cover mounting slot 210, the first elastic member 212 will be squeezed by the inclined surface, and the first elastic member 212 moves downward until the fixing hole 500 is aligned with the first elastic member 212. The first elastic member 212 can extend into the fixing hole 500, so that the upper cover 130 is fixed, and the cooperation with the slide slot 211 and the slider 400 fixes the upper cover 130 in the upper cover mounting slot 210. Finally, the fixing pin 600 is extended from the first mounting slot 213 into the second mounting slot 410, so that the upper cover fixed in the upper cover mounting slot 210 is further fixed, so that the upper cover 130 is better fixed on the bracket body 100.

[0048] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
