Description

Technical Field

[0001] The utility model relates to the field of oral orthodontics, in particular to a traction hook used for oral orthodontics. Background Art

[0002] Orthodontics, also known as dental correction, is a treatment method that improves oral function and aesthetics by adjusting the position of teeth and jaws. By adjusting the arrangement and occlusion of teeth, orthodontic treatment can solve chewing problems, pronunciation problems, breathing problems, etc., thereby improving the overall function of the oral cavity.

[0003] During orthodontic treatment, the traction hook, as a key auxiliary tool, plays an important role in transmitting traction and guiding the teeth to move in the predetermined direction. However, as the orthodontic treatment progresses, the teeth will gradually move to new positions under the action of continuous traction. In this process, the movement of the teeth will also correspondingly drive the traction hook to produce a certain displacement or deformation; when orthodontic treatment continues for a period of time, due to the movement of the teeth and changes in the oral environment, the originally tightened traction hook may gradually become loose. This loosening will not only reduce the efficiency of the traction hook in transmitting traction, but may also affect the accuracy and speed of tooth movement, thereby adversely affecting the effect of orthodontic treatment.

[0004] Therefore, there is an urgent need for a traction hook for orthodontics to solve the above problems. Utility Model Content

[0024] The adjusting assembly 4 includes a collecting roller 41 rotatably connected to the inner wall of the shell 3, the top of the collecting roller 41 extends to the outside of the shell 3 and is fixedly connected to a rotating block 1 42, and a through hole 43 adapted to the arch wire 2 is opened on the surface of the collecting roller 41, and one side of the arch wire 2 sequentially passes through the inner cavity of the shell 3 and the through hole 43, and the right side of the inner cavity of the shell 3 is rotatably connected to a bidirectional threaded rod 1 44 and a bidirectional threaded rod 2 45 from top to bottom, the left end of the bidirectional threaded rod 1 44 passes through the outside of the shell 3 and is fixedly connected to a rotating block 2 46, and the left end of the bidirectional threaded rod 2 45 is rotatably connected to the shell 3, and the surfaces of the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45 are respectively fixedly connected to a gear 1 47 and a gear 2 48, and the gear 1 47 and the gear 2 48 are meshed. Both sides of the surfaces of the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45 are threadedly connected to movable plates 49, and the opposite sides of the two movable plates 49 are fixedly connected to a clamping block 410, which cooperates with the collecting roller 41.

[0025] Specifically, the surfaces of the first rotating block 42 and the second rotating block 46 are both provided with a plurality of grooves 411 distributed in an annular shape at equal intervals.

[0026] In this embodiment, the groove 411 is provided to facilitate the user to rotate the first rotating block 42 and the second rotating block 46 , thereby saving time and effort.

[0027] Specifically, the centers of the surfaces of the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45 are both rotatably connected to a support block 412 , and one side of the support block 412 is fixedly connected to the housing 3 .

[0028] In this embodiment: through the setting of the support block 412, the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45 will rotate in the inner cavity of the support block 412 when they rotate, which plays a role in supporting the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45, thereby improving the safety of the bidirectional threaded rod 1 44 and the bidirectional threaded rod 2 45 when they rotate.

[0029] Specifically, two T-shaped guide grooves 413 are provided on both sides of the front side of the inner cavity of the shell 3 , and the inner cavity of the T-shaped guide groove 413 is slidably connected to a T-shaped guide block 414 , and one side of the T-shaped guide block 414 is fixedly connected to the movable plate 49 .

[0030] In this embodiment, through the coordinated use of the T-shaped guide groove 413 and the T-shaped guide block 414 , the movable plate 49 will drive the T-shaped guide block 414 to slide in the inner cavity of the T-shaped guide groove 413 when it moves, thereby limiting and guiding the movable plate 49 .

[0031] Specifically, a working groove 415 is formed on the inner wall of the housing 3 , and the gear 1 47 and the gear 2 48 are both located in the inner cavity of the working groove 415 .

[0032] In this embodiment, the working groove 415 is provided to place the gear 1 47 and the gear 2 48 , thereby preventing the gear 1 47 and the gear 2 48 from colliding with the collecting roller 41 when the gear 1 47 and the gear 2 48 rotate.

[0033] The working principle and use process of this utility model:

[0034] When in use, the two traction hooks 1 are respectively connected to the support teeth and the orthodontic teeth. As the orthodontic quality progresses, the teeth will gradually move to the new position under the continuous traction force. At this time, it is necessary to rotate the rotating block 2 46. When the rotating block 2 46 rotates, it will drive the bidirectional threaded rod 1 44 to rotate. When the bidirectional threaded rod 1 44 rotates, it will drive the gear 1 47 to rotate in the same direction. The gear 1 47 will drive the gear 2 48 to rotate. When the gear 2 48 rotates, it will drive the bidirectional threaded rod 2 45 to rotate. As the bidirectional threaded rod 2 45 and the bidirectional threaded rod 1 44 rotate, and the two movable plates are driven by the transmission of the surface threads 49 moves in opposite directions, the movable plate 49 drives the clamping block 410 to move in opposite directions away from the collecting roller 41, releasing the lock of the collecting roller 41, and further rotating the rotating block 1 42. The rotating block 1 42 drives the collecting roller 41 to rotate. Since the arch wire 2 passes through the through hole 43, the collecting roller 41 will wrap the arch wire 2 when it rotates. When the arch wire 2 becomes tight, the rotating block 2 46 is rotated in the opposite direction. Under the coordinated use of the above structure, the clamping block 410 moves toward the collecting roller 41 to lock the collecting roller 41, so that the tension of the arch wire 2 can be adjusted, ensuring that the traction of the traction hook 1 remains continuous and accurate.
