Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-4 As shown, this embodiment provides a self-locking intermaxillary anchorage bracket, including: a mesh base 1 and a base 2.

[0020] like Figure 1-4 As shown, in this embodiment, the base 2 is installed on the top of the back of the net base 1. A support 3 is provided on the top of the base 2, and a retaining plate 4 is provided on the top of the support 3. An arc groove 302 is formed at the center of the support 3, and a locking cover 5 is provided inside the arc groove 302. Extension legs 501 are provided at both ends of the bottom of the locking cover 5. Archwire grooves 301 are longitudinally formed on both sides of the arc groove 302, and an archwire 6 is provided inside the archwire grooves 301. A screw sleeve 502 is provided at the center of the locking cover 5, and a fixing screw 403 is provided at the center of the retaining plate 4. The back of the net base 1 is fitted with teeth and fixed with glue. The base 2 connects the net base 1 and the support 3. The archwire 6 is placed into the archwire groove 301 and fitted. The locking cover 5 is placed into the arc groove. In section 302, the top is screwed into the threaded sleeve 502 of the lock cover 5 by the mounting screw 402 on the card plate 4, thereby installing the lock cover 5 on the card plate 4. The extension leg 501 at the bottom of the lock cover 5 is located on both sides of the lock cover 5 and extends to fit the bottom of the arc groove 302, leaving the middle position empty. When the extension leg 501 is in the arc groove 302 and does not contact the bow wire 6 in the bow wire groove 301, the bow wire 6 is in a movable state and can move and adjust its position in the bracket. By rotating the lock cover 5 ninety degrees, the extension leg 501 is rotated from the arc groove 302 to the bow wire groove 301. The extension leg 501 fits against the top of the bow wire 6 and fixes and presses the bow wire 6 to achieve the fixation and adjustment of the bow wire 6.

[0021] like Figure 1-4As shown, in this embodiment, a limiting groove 303 is provided at the bottom of the arc groove 302, and the extension leg 501 is embedded in the limiting groove 303; wherein, the protruding part of the extension leg 501 that is in contact with the edge of the limiting groove 303 is embedded in the limiting groove 303, hooking the limiting groove 303 to fix the lock cover 5, and the limiting groove 303 is in contact with the edge of the arc groove 302, without affecting the rotation of the extension leg 501 in the arc groove 302.

[0022] like Figure 1-4 As shown, in this embodiment, the card plate 4 is fixedly connected to the extension plate 401 around its perimeter. The extension plate 401 has a mounting screw 402 at its center, and the bracket body 3 has a mounting screw hole 304 corresponding to the mounting screw 402. The card plate 4 is screwed into the mounting screw hole 304 of the bracket body 3 through the mounting screw 402 on the extension plate 401. First, the lock cover 5 is placed into the arc groove 302, and then the card plate 4 is installed on the bracket body 3, so that the card plate 4 can be removed from the bracket body 3. After removal, it is convenient to put the archwire 6 directly into the bracket body 3, making the installation of the archwire 6 on the bracket body 3 faster and more convenient.

[0023] like Figure 1-4 As shown, the back of the card plate 4 in this embodiment has a bottom hole 404, and a top ring 503 is fixedly connected to the screw sleeve 502 near the top. The top ring 503 is located in the bottom hole 404. When the fixing screw 403 passes through the card plate 4 and is screwed into the screw sleeve 502 of the lock cover 5, the entire lock cover 5 is pulled upward. At this time, the extension leg 501 is embedded in the limiting groove 303 to fix and limit the entire lock cover 5 and the bracket body 3. After rotating the lock cover 5, the extension leg 501 moves out from the limiting groove 303 and presses on the bow wire 6. At this time, the top ring 503 presses against the bottom hole 404, replacing the fixing work of the extension leg 501 in the limiting groove 303, so that the lock cover 5 can maintain relative stability with the bracket body 3 or the card plate 4 whether the bow wire 6 is pressed or released.

[0024] like Figure 1-4 As shown, in this embodiment, the depth of the bow wire groove 301 and the thickness of the bow wire 6 are the same; wherein, when the bow wire 6 is in the bow wire groove 301, the top and the bottom of the arc groove 302 are horizontal, so that when the extension leg 501 of the locking cover 5 is rotated to the bow wire groove 301, it can directly press the top of the bow wire 6, thereby fixing the bow wire 6.

[0025] like Figure 1-4 As shown, the mesh base 1 in this embodiment is arc-shaped and has multiple sets of small holes. The small holes on the mesh base 1 are filled with adhesive, which makes it easier for the mesh base 1 to be bonded to the teeth. The arc-shaped surface can also better fit the tooth surface and avoid gaps between the mesh base 1 and the teeth.

[0026] Working principle: First, the mesh base 1 is fixed to the tooth surface with adhesive. Then, the archwire 6 is placed in the archwire groove 301 of the bracket body 3. Next, the extension leg 501 of the locking cover 5 is aligned with the arc groove 302 and inserted into the archwire groove 301. The locking cover 5 is rotated to embed the extension leg 501 into the limiting groove 303. Finally, the retaining plate 4 is covered, and the mounting screws 402 are screwed into the extension plates 401 at the four corners to fix the retaining plate 4. At the same time, the middle hole is aligned with the threaded sleeve 502 on the locking cover 5 and the fixing screw 403 is screwed in to fix the locking cover 5 and the retaining plate 4. At this time, the locking cover 5 is located in the arc groove 302. The extension leg 501 at the bottom is embedded in the limiting groove 303, which serves as a preliminary limiting function. When it is necessary to fix the bow wire 6, rotate the lock cover 5 about 90 degrees to move the extension leg 501 out of the limiting groove 303 and press it on the bow wire 6 to achieve clamping and fixing of the bow wire. Then, tighten the fixing screw 403 so that it passes through the card plate 4 and locks into the screw sleeve 502 of the lock cover 5, which drives the top ring 503 to push upward to tighten the bottom hole 404, thereby further stabilizing the position of the lock cover 5 and preventing it from loosening. In the whole process, the lock cover 5 is opened and closed by rotation. The structure is simple and reliable, has a long service life, and is easy to adjust.
