DETAILED DESCRIPTION
[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.
[0024] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.
[0025] like Figure 1As shown, in this embodiment, an invisible brace with the effect of preventing the posterior teeth from being depressed comprises a brace body 1, two sides of the brace body 1 are provided with opposite bases 100, a front side surface of the base 100 is provided with a mounting groove 201 along its length direction, a slidable mounting plate 210 is provided on the front side surface of the base 100, a rotatable rotating circular plate 220 is provided on the front side surface of the mounting plate 210, a traction assembly for pulling an elastic rubber ring (which is an existing structure) is provided on the rotating circular plate 220, and a mounting plate 210 is provided on the mounting plate 210 for pulling the mounting plate 210 in a certain direction. A positioning assembly is slidably mounted on the base 100 for positioning, a rotatable mounting circular plate 230 is provided on the rotating circular plate 220, a slidable mounting rod 500 is provided on the mounting circular plate 230, one end of the mounting rod 500 passes through the mounting plate 210 and extends into the mounting groove 201, a disassembly assembly is provided on the mounting rod 500 located in the mounting groove 201, the mounting circular plate 230 rotates to drive the disassembly assembly to be disassembled and assembled in the mounting groove 201, and a locking assembly for locking the rotation of the rotating circular plate 220 and the mounting circular plate 230 is provided on the mounting plate 210.
[0026] In this embodiment, the mounting plate 210 slides on the base 100 so that the traction assembly on the rotating circular plate 220 can be moved to a suitable position on the base 100, and then the mounting plate 210 is positioned on the bottom plate by the positioning assembly so that the mounting plate 210 cannot move on the base 100, that is, the position of the traction assembly is positioned. At this time, the mounting rod 500 is driven to rotate by the mounting circular plate 230 so that the mounting rod 500 can be installed in the mounting groove 201 through the disassembly assembly. When one end of the mounting rod 500 is installed in the mounting groove 201, the mounting rod 500 can install the mounting plate 210 on the base 100 through the mounting circular plate 230, thereby realizing the installation of the mounting plate 210 on the base 100; There are two brace bodies 1. When the mounting plate 210 is mounted on the base 100 through the positioning assembly and the disassembly assembly, the traction assembly on the rotating circular plate 220 is mounted on the base 100 along with the mounting plate 210. At this time, the two brace bodies 1 are respectively worn on the upper teeth and the lower teeth. Then, one end of the elastic rubber band is mounted on the traction assembly of the upper teeth, and the other end of the elastic rubber band is mounted on the traction assembly of the lower teeth. When the two brace bodies 1 are worn on the upper teeth and the lower teeth, the elastic rubber band can apply force to the corrected teeth through the brace bodies 1, thereby better correcting the teeth. The mounting circular plate 230 is fixedly mounted on the other end of the mounting rod 500, and the mounting rod 500 on the mounting circular plate 230 penetrates the rotating circular plate 220, so that the rotating circular plate 220 is sleeved on the mounting rod 500, and the mounting plate 210 moves through the mounting rod 500 to bring the mounting ring and the rotating circular plate 220 to move. When the mounting plate 210 is mounted at different positions on the base 100, the traction assembly on the rotating circular plate 220 is also mounted at different positions on the base 100. At this time, the traction assembly can apply traction force in different directions through the elastic rubber ring, so as to better correct the teeth; The mouthpiece body 1 is provided with an embedding groove (not shown in the figure) for the base 100 to embed. By fixing the base 100 in the embedding groove, the protrusion of the base 100 on the mouthpiece body 1 is reduced, making the mouthpiece body 1 more comfortable when worn on the teeth. The rotating circular plate 220 can drive the traction assembly to rotate, so that the direction of the traction assembly can be adjusted, so that the elastic rubber ring can be installed on the traction assembly better, and then the elastic rubber ring can better apply force to correct the teeth; A driving groove (not shown in the figure) for driving the rotating circular plate 220 to rotate is provided on the side wall of the rotating circular plate 220. The driving groove facilitates driving the rotating circular plate 220 to rotate, so that the direction of the traction assembly can be better adjusted. Among them, the mounting plate 210 can be positioned at different positions on the base 100 through the positioning component. When the mounting plate 210 is mounted on the base 100 through the disassembly component, the traction component on the rotating circular plate 220 can be fixedly installed at different positions of the base 100. When the disassembly component releases the installation of the mounting rod 500 in the mounting groove 201, the mounting plate 210 can be removed from the base 100, that is, the traction component is removed from the base 100. Compared with the existing ones, the traction component of the invisible braces with the effect of preventing the depression of the posterior teeth is more convenient to disassemble and assemble at different positions on the base 100 during actual use, so as to facilitate actual use. The rotation of the rotating circular plate 220 is locked by the locking assembly, so that the traction assembly can always maintain the adjusted direction. At the same time, the rotation of the mounting circular plate 230 can also be locked by the locking assembly, so as to prevent the mounting circular plate 230 from rotating when the disassembly assembly installs one end of the mounting rod 500 in the mounting groove 201, so that the mounting circular plate 230 drives the mounting rod 500 to rotate, causing the disassembly assembly on the mounting rod 500 to release the mounting rod 500 from the mounting groove 201, thereby affecting the actual use. In actual use, a tooth socket is provided on the brace body 1. When the two brace bodies 1 are worn on the teeth, they usually need to be used in conjunction with a bite glue (which is an existing structure). The bite glue is provided with a bite groove that matches the tooth socket. The upper teeth and the lower teeth drive the tooth sockets on the two brace bodies 1 to bite in the bite groove on the bite glue, so that the two brace bodies 1 can better fit on the corresponding teeth, thereby avoiding the misfit between the brace body 1 and the teeth, resulting in excessive movement of the teeth when the brace body 1 is used to move and correct the teeth, causing the posterior teeth to be depressed.
[0027] like Figure 1-4 As shown, in this embodiment, the front side of the base 100 and located at the upper and lower sides of the installation groove 201 are provided with opposite slots 202, and the slots 202 are provided with multiple slots along the direction of the installation groove 201; The positioning assembly includes an inserting plate 400 disposed on the rear side of the mounting plate 210 and opposite to the mounting plate 210 . The inserting plate 400 is inserted into the corresponding slot 202 to achieve the sliding positioning of the inserting plate 400 on the mounting plate 210 .
[0028] In this embodiment, by setting the slot 202 and the plug board 400, the plug board 400 is fixedly mounted on the mounting plate 210, and the plug board 400 on the mounting plate 210 is inserted into the slot 202, so that the position of the mounting plate 210 on the base 100 is positioned.
[0029] like Figure 1-4 As shown, in this embodiment, positioning grooves 203 are provided on the side walls opposite to the mounting groove 201 along the length direction thereof; The disassembly assembly includes a disassembly block 300 disposed on the mounting rod 500 . The mounting circular plate 230 rotates to drive both ends of the disassembly block 300 to snap into corresponding positioning grooves 203 , thereby achieving the installation of the mounting plate 210 on the base 100 .
[0030] In this embodiment, by setting the positioning groove 203 and the disassembling block 300, the disassembling block 300 is fixedly installed on the mounting rod 500. When the plug plate 400 on the mounting plate 210 is inserted into the corresponding slot 202, the disassembling block 300 on the mounting rod 500 will be inserted into the mounting groove 201. At this time, by rotating the mounting circular plate 230, the mounting circular plate 230 rotates to drive the mounting rod 500 to rotate, and the mounting rod 500 rotates to drive the disassembling block 300 to rotate, so that the two ends of the disassembling block 300 are inserted into the corresponding positioning grooves 203, and the mounting rod 500 is installed in the mounting groove 201, that is, the mounting plate 210 is installed on the base 100. The mounting rod 500 is driven to rotate by the mounting circular plate 230, so that the mounting rod 500 drives both ends of the disassembly block 300 to slide out of the positioning groove 203, thereby releasing the mounting rod 500 from the mounting groove 201, that is, the mounting plate 210 is released from the base 100; In actual use, the installation of the mounting plate 210 at different positions on the base 100 can be achieved by inserting the plug plate 400 on the mounting plate 210 into different slots 202, and then rotating the mounting circular plate 230 to snap the two ends of the disassembly block 300 into the corresponding positioning grooves 203, so that the traction component can be installed at different positions on the base 100. When the elastic rubber ring is installed on the traction component, the traction component can apply force to the elastic rubber ring in different directions.
[0031] like Figure 1-6 As shown, in this embodiment, a plurality of circular holes 601 are opened on the rotating circular plate 220 along its circumference, and a plurality of connecting holes 311 connected to the circular holes 601 are opened on the mounting circular plate 230 along its circumference; The locking assembly includes a locking rod 320 disposed on the mounting plate 210 , one end of the locking rod 320 passes through the circular hole and is inserted into the communicating hole 311 , thereby locking the rotating circular plate 220 and the mounting circular plate 230 .
[0032] In this embodiment, by setting the circular hole 601, the connecting hole 311 and the locking rod 320, the locking rod 320 is fixedly mounted on the mounting plate 210. When one end of the locking rod 320 passes through the circular hole 601 and is inserted into the connecting hole 311, the locking rod 320 can lock the rotation of the rotating circular plate 220 and the mounting circular plate 230. The mounting circular plate 230 is made of an elastic material. When the mounting plate 210 is mounted on the base 100, the mounting rod 500 is pulled by the mounting circular plate 230 to move a distance, and then the rotating circular plate 220 and the mounting circular plate 230 are pulled to make the circular hole 601 and the connecting hole 311 slide out of the locking rod 320. Then, the direction of the traction assembly is adjusted to a suitable position by the rotating circular plate 220. Then, the mounting rod 500 is pushed to move by the mounting circular plate 230 so that the disassembly block 300 on the mounting rod 500 is completely located in the mounting groove 201. At this time, the locking rod 320 One end of the mounting plate 230 passes through the circular hole 601 and is inserted into the connecting hole 311. Then, one end of the mounting circular plate 230 is tilted up so that the connecting hole 311 on the mounting circular plate 230 slides out of the locking rod 320. The mounting circular plate 230 is rotated by the tilted end of the mounting circular plate 230 so that the mounting rod 500 drives the two ends of the disassembly block 300 to be inserted into the corresponding positioning grooves 203, thereby realizing the installation of the mounting plate 210 on the base 100. Finally, the tilting of one end of the mounting circular plate 230 is released so that the locking rod 320 is inserted into the connecting hole 311 again, and the rotation of the mounting circular plate 230 is locked. In actual use, the upper end surface of the mounting circular plate 230 is fixedly mounted with a plurality of convex plates (not shown in the figure) along its circumference and one end of which extends out of the mounting circular plate 230 , so that one end of the mounting circular plate 230 can be driven to tilt up through the convex plates.
[0033] like Figure 1-6 As shown, in this embodiment, the traction assembly includes support blocks 240 disposed on the rotating circular plate 220 and opposite to each other, a support plate 250 is disposed between the two support blocks 240, a traction rod 260 is disposed on the support plate 250, and a traction groove 261 is disposed on the traction rod 260 for the elastic rubber ring to be wound around.
[0034] In this embodiment, by setting the support block 240, the support plate 250, the traction rod 260 and the traction groove 261, the support block 240 is fixedly mounted on the rotating circular plate 220, the two ends of the support plate 250 are fixedly mounted on the corresponding rotating circular plate 220, the traction rod 260 is fixedly mounted on the support plate 250, and the elastic rubber ring is wound around the traction groove 261, so that the installation of the elastic rubber ring on the rotating circular plate 220 can be achieved; In actual use, the traction rod 260 is located at the center of the rotating circular plate 220. When the rotating circular plate 220 rotates, the traction rod 260 can rotate on itself, so that the direction of the traction groove 261 on the traction rod 260 can be adjusted, thereby making the elastic rubber ring better wrapped in the traction groove 261, and then making the elastic rubber ring better apply force to the corrected teeth, thereby improving the correction effect of the elastic rubber ring on the teeth.
[0035] Working principle: First, insert the plug plate 400 on the mounting plate 210 into the corresponding slot 202 to fix the mounting plate 210 on the base 100. Then, pull the mounting circular plate 230 to make the locking rod 320 slide out of the circular hole 601 and the connecting hole 311. At this time, the direction of the traction groove 261 can be adjusted by driving the rotating circular plate 220 to rotate. After the adjustment of the direction of the traction groove 261 is completed, push the mounting circular plate 230 to make one end of the locking rod 320 pass through the circular hole 601 and insert into the connecting hole 311. At the same time, the disassembly block 300 is located in the mounting groove 201. Then, The convex plate is used to lift up one end of the mounting circular plate 230 so that the connecting hole 311 is separated from the locking rod 320. Then, the mounting circular plate 230 is driven to rotate by the convex plate. The mounting circular plate 230 drives the two ends of the disassembly block 300 to be inserted into the corresponding positioning grooves 203 through the mounting rod 500, so as to realize the installation of the mounting plate 210 on the base 100. Finally, the two braces bodies 1 are worn on the upper and lower teeth, and the two ends of the elastic rubber band are wrapped around the corresponding traction grooves 261, so that the elastic rubber band can apply force to the teeth to be corrected through the braces body 1, thereby better correcting the teeth.
[0036] In conclusion, the above is only a preferred embodiment of the present invention, and 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 patent of the present invention.
