Abstract
Description
Technical Field
[0001] This invention relates to the field of orthodontic auxiliary devices, specifically to an orthodontic auxiliary device. Background Technology
[0002] Orthodontic assistive devices are an important means of correcting skeletal Class III maxillary hypoplasia in adolescents. These include intraoral devices such as arch expanders. Among them, the headgear-type strong support traction device adjusts the position of the jawbone through external traction force and plays a significant role in the correction of skeletal deformities.
[0003] Existing headgear-type strong support traction devices require adjustment of traction intensity based on different usage times. In addition, when wearing the headgear-type strong support traction device, the user needs to observe a mirror while pulling the elastic band to a fixed position. Therefore, the device is inconvenient to wear.
[0004] Combining the above issues, we find that existing orthodontic assistive devices on the market cannot simultaneously avoid the problems mentioned above when in use.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1: Please refer to Figures 1-6 and Figures 8-10 The present invention provides a technical solution: an orthodontic auxiliary device, including a traction device 1, a quick installation and adjustment structure 2 provided on the outside of the traction device 1, and a timing structure 3 provided on the outside of the traction device 1. The quick-installation adjustment structure 2 includes an installation unit 21, which is located on the outside of the traction device 1. The installation unit 21 includes a rectangular block 2101, and a movable chamber 2112 is slidably connected inside the rectangular block 2101. Two magnets 2111 are fixedly connected to the upper surface of the movable chamber 2112, and two force springs 2113 are fixedly connected to the inner top wall of the movable chamber 2112. A lifting plate 2121 is fixedly connected to the bottom end of the two force springs 2113. The lifting plate 2121 is slidably connected inside the movable chamber 2112, and two hooks 2114 are fixedly connected to the right side of the lifting plate 2121.
[0023] As a further limitation of the present invention, two rectangular plates 2118 are fixedly connected to the bottom surface of the lifting plate 2121. The inner walls of the two rectangular plates 2118 are rotatably connected to a long shaft 2120. A flip plate 2117 is fixedly connected to the outer surface of the long shaft 2120. Two first limiting plates 2102 are fixedly connected to the outer surface of the long shaft 2120. A second limiting plate 2109 is fixedly connected to the side of the two rectangular plates 2118 that are far apart from each other. By setting the installation unit 21, the speed at which the user connects the traction elastic band 2108 and the hook 2114 can be accelerated. The user can complete the purpose of wearing the device without the need for a mirror, thereby greatly increasing the wearing speed of the device and improving the wearing experience.
[0024] See also Figure 10 A roller 2119 is rotatably connected to the inner wall of the flip plate 2117. The outer surface of the roller 2119 contacts the inner bottom wall of the moving chamber 2112. Two sliding plates 2115 are slidably connected inside the rectangular block 2101. Each sliding plate 2115 has a sliding block 2116 slidably connected inside. The two sliding blocks 2116 are fixedly connected to the front and back of the moving chamber 2112 on their respective sides. By setting the roller 2119, which is rotatably connected to the inner wall of the flip plate 2117 and contacts the inner bottom wall of the moving chamber 2112, the sliding friction between the flip plate 2117 and the moving chamber 2112 can be converted into rolling friction, which greatly reduces resistance and wear, making the flip plate 2117 rotate and move more smoothly and avoiding jamming when installing the traction rubber band 2108. The two sliding plates 2115 inside the rectangular block 2101 and their respective sliding blocks 2116 constitute the guide structure of the moving chamber 2112. The sliding block 2116 is connected to the front and back of the moving chamber 2112. When moving, it slides along the sliding plate 2115. The sliding plate 2115 can also be adjusted in position. The dual cooperation provides stable guidance, prevents the moving chamber 2112 from shifting, ensures that the magnet 2111 and the iron block 2107 are accurately attracted, and the hook 2114 and the traction rubber band 2108 are accurately connected, thus improving the stability of the device.
[0025] See also Figure 2A support pad 2106 is fixedly connected to the outer surface of the traction device 1. A mounting bracket 2110 is provided on the outer side of the traction device 1. The inner wall of the rectangular block 2101 is fixedly connected to the outer surface of the mounting bracket 2110. By providing the support pad 2106, the support pad 2106 is fixed to the outer surface of the traction device 1, which can conform to the contour of the user's head, distribute pressure, and avoid discomfort caused by local pressure.
[0026] See also Figure 1 and Figure 2 An elastic band 2105 is fixedly connected to the outer surface of the traction device 1, and a fixing ring 2104 is fixedly connected to the outer surface of the traction device 1. By setting the elastic band 2105 and the fixing ring 2104, the device can be stably fixed to the user's head.
[0027] See also Figure 3 The outer side of the traction device 1 is provided with a traction plate 2103. Two traction rubber bands 2108 are fixedly connected to the outer surface of the traction plate 2103. An iron block 2107 is fixedly connected to the outer surface of each traction rubber band 2108. The traction rubber band 2108 is fixed to the outer surface of the traction plate 2103, and one end of it is connected to the iron block 2107. When the user wears the device, the iron block 2107 fits against the lip under the action of gravity. When the magnet 2111 on the moving chamber 2112 approaches, the two quickly attract the magnet 2111 through magnetic interaction. When the moving chamber 2112 moves, it will pull the iron block 2107, thereby causing the traction rubber band 2108 to gradually straighten. The traction rubber band 2108 can be stably put into the stretched state without manual pulling. This magnetic connection structure eliminates the alignment operation, simplifies the installation process of the traction rubber band 2108, and allows the user to quickly complete the traction preparation, improving the ease of use of the device.
[0028] The specific implementation method of this embodiment is as follows: When the device needs to be used, the elastic band 2105 is used to fix the entire device to the user's face. The elastic band 2105 can be flexibly adjusted according to the user's head circumference to ensure that the device is worn securely and comfortably. Then, the user puts the traction plate 2103 in their mouth. The traction plate 2103 conforms to the internal structure of the oral cavity, which can reduce the foreign body sensation when wearing it. It should be understood that the traction plate 2103 is customized according to the different oral cavity of each patient. Only the traction elastic band 2108 needs to be installed during the customization process. At this time, the two iron blocks 2107 will naturally stick to the user's lower lip under the action of gravity, which is convenient for subsequent cooperation with the magnet 2111. Then the user pushes down the pressing plate 304. The locking block 302 will be pushed into the interior of the rectangular block 2101. The sliding engagement between the locking block 302 and the inner wall of the rectangular block 2101 ensures smooth movement. Therefore, the locking block 302 does not limit the movement chamber 2112 at this time. Then, the pressing plate 304 and the movement chamber 2112 can be pushed to move towards the patient's mouth. During the movement, the cooperation between the sliding plate 2115 and the sliding block 2116 provides a stable guide for the movement chamber 2112, preventing it from deviating. During the movement, when the roller 2119 moves to the right side of the mounting bracket 2110, the roller 2119 and the flipping plate 2117 will rotate 90 degrees counterclockwise around the center of the long axis 2120 under the action of gravity. The rolling characteristics of the roller 2119 reduce the friction during movement. Therefore, at this time, the flipping plate 2117 and the roller 2119 are perpendicular to the ground, and when the long shaft 2120 rotates, the first limiting plate 2102 will rotate to the position where it contacts the bottom surface of the second limiting plate 2109. The contact between the first limiting plate 2102 and the second limiting plate 2109 forms an effective mechanical limit, which means that the long shaft 2120 can no longer rotate counterclockwise. As the moving chamber 2112 continues to move, the magnet 2111 fixed on the surface of the moving chamber 2112 will move to the vicinity of the iron block 2107. Under the action of magnetic force, the iron block 2107 will be quickly attracted by the magnet 2111, eliminating the trouble of manual alignment. Then, the moving chamber 2112 is pulled in the opposite direction. At this time, the magnet 2111 will pull the iron block 2107 and traction. The elastic band 2108 is in a taut and stretched state. As the moving chamber 2112 continues to move, the roller 2119 will contact the inclined surface of the inner bottom wall of the rectangular block 2101, and the roller 2119 will always be pushed by the inclined surface of the rectangular block 2101. However, the roller 2119 cannot rotate counterclockwise under the limitation of the long axis 2120, the first limiting plate 2102, and the second limiting plate 2109. Therefore, the roller 2119 and the flipping plate 2117 will always move into the interior of the rectangular block 2101 in a vertical state. Thus, the vertical flipping plate 2117 will push the lifting plate 2121 to move upward. The sliding connection between the lifting plate 2121 and the moving chamber 2112 ensures the smoothness of the movement. The lifting plate 2121 drives the hook 2114 to move upward synchronously.The hook 2114 is positioned accurately inside the traction elastic band 2108. As the moving chamber 2112 continues to reset, the tension on the traction elastic band 2108 gradually exceeds the magnetic force between the magnet 2111 and the iron block 2107. Therefore, the magnet 2111 and the iron block 2107 gradually disconnect. At this point, the hook 2114 bears the tension of the traction elastic band 2108. The force spring 2113 adapts to the tension, providing cushioning for the lifting plate 2121, until the moving chamber 2112 moves back above the two locking blocks 302. The two locking blocks 302, under the elastic force of the first reset spring 303, reposition the moving chamber 2112, thus completing the installation of the traction elastic band 2108. The entire process does not require a mirror, significantly improving wearing efficiency.
[0029] Example 2: Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 11 and Figure 12 The present invention provides a technical solution: an orthodontic auxiliary device. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The quick installation adjustment structure 2 also includes an adjustment unit 22. The adjustment unit 22 is disposed on the outside of the traction device 1. The adjustment unit 22 can adjust the traction intensity according to the user's usage time.
[0030] As a further limitation of the present invention, the adjustment unit 22 includes two threaded shafts 2208. The outer surface of each threaded shaft 2208 is threadedly connected to the inner wall of the traction device 1. A spiral cylinder 2205 is fixedly connected to the inner wall of each threaded shaft 2208. The outer surface of each spiral cylinder 2205 is rotatably connected to the inner wall of the rectangular block 2101. The outer surfaces of the two spiral cylinders 2205 are rotatably connected to the inner wall of the mounting frame 2110. A transmission shaft 2201 is provided inside each threaded shaft 2208. A spiral shaft 2207 is fixedly connected to one end of each transmission shaft 2201 near the spiral cylinder 2205. The outer surface of each spiral shaft 2207 is slidably connected to the inside of the spiral cylinder 2205. By setting the adjustment unit 22, the pressure of the user pressing the transmission shaft 2201 when lying down can be converted into rotational power and applied to the spiral cylinder 2205, thereby driving the spiral cylinder 2205 and the threaded shaft 2208 to rotate. This allows the traction intensity of the device on the jaw to be adjusted without the need for manual adjustment by the user.
[0031] See also Figure 12Two fixing blocks 2206 are fixedly connected to the left side of the rectangular block 2101. A cross 2202 is fixedly connected to the right side of each fixing block 2206. Each cross 2202 is located inside the spiral cylinder 2205. The outer surface of each spiral shaft 2207 is slidably connected to the outer surface of the cross 2202. The cross 2202 is fixed to the right side of the fixing block 2206 and located inside the spiral cylinder 2205, with its outer surface slidably connected to the spiral shaft 2207. When the spiral shaft 2207 is in the drive shaft 22... When the 01 pushes and moves towards the spiral cylinder 2205, the cross 2202 restricts the circumferential rotation of the spiral shaft 2207, allowing it to move only axially. This ensures that the spiral stripes on the outer surface of the spiral shaft 2207 can be accurately embedded into the spiral grooves on the inner wall of the spiral cylinder 2205, thereby stably converting linear motion into the rotational motion of the spiral cylinder 2205. This limiting effect ensures the accuracy of power transmission, avoids transmission failure caused by the rotation of the spiral shaft 2207, and allows the adjustment unit 22 to reliably adjust the traction strength, thus improving the stability of the device operation.
[0032] Please see Figure 6 The inner wall of the rectangular block 2101 is rotatably connected to a transmission frame 2203. The outer surface of the transmission frame 2203 and the outer surfaces of the two spiral cylinders 2205 are fixedly connected to two transmission gear belt sets 2204. By setting the transmission frame 2203 and the transmission gear belt sets 2204, power can be easily transmitted to the two spiral shafts 2207.
[0033] The specific implementation of this embodiment is as follows: When the wearer wants to wear the device at night, there is no need for complicated manual operation. The user only needs to sit on the bed in a normal posture and then lie down naturally. During this process, the support pad 2106 on the outer surface of the traction device 1 will fit against the head, providing comfortable support and avoiding pressure during wear. When the user lies down, the two drive shafts 2201 will first contact the bed surface. The reaction force of the bed surface will push the drive shafts 2201 to move towards the spiral cylinder 2205. The spiral stripes fixed on the outer surface of the spiral shaft 2207 correspond precisely to the spiral grooves opened on the inner wall of the spiral cylinder 2205. This structural design can stably convert linear motion into rotational motion. Therefore, the axial movement of the spiral shaft 2207 will eventually drive the spiral cylinder 2205 to rotate. When the spiral cylinder 2205 rotates, it will synchronously drive the threaded shaft 2208 to rotate through its fixed connection with the threaded shaft 2208. The inner wall of the traction device 2101 is connected to the inner wall of the traction device 2108 by a thread, and the inner wall of the rectangular block 2101 is fixedly connected to the outer surface of the mounting frame 2110. Using this threaded connection, the rotation of the threaded shaft 2208 is converted into the horizontal movement of the mounting frame 2110. It should be noted that the mounting frame 2110 is rotatably connected to the two spiral cylinders 2205. Under the joint limiting action of the two spiral cylinders 2205, the mounting frame 2110 is restricted in its rotational freedom and can only move in the horizontal direction. Therefore, the mounting frame 2110 will move the rectangular block 2101 steadily to the left. As the rectangular block 2101 moves to the left, the internal moving chamber 2112 and related components will also move synchronously, thereby increasing the pulling force of the traction elastic band 2108 on the jaw. This achieves the purpose of automatically increasing the traction intensity without manual adjustment during sleep, making nighttime orthodontic treatment more convenient and efficient. At the same time, it can automatically adapt to the traction needs according to the wearer's sleeping posture.
[0034] Example 3: Please refer to Figure 6 and Figure 13 The present invention provides a technical solution: an orthodontic auxiliary device. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The timing structure 3 can ensure that the traction on the teeth and jaws can be automatically released when the user wears it at night while sleeping.
[0035] As a further limitation of the present invention, the timing structure 3 includes two first return springs 303. The bottom end of each first return spring 303 is fixedly connected to the inner wall of the rectangular block 2101, and the top end of each first return spring 303 is fixedly connected to a locking block 302. The outer surface of each locking block 302 is engaged with the interior of the movable chamber 2112. A pressing plate 304 is slidably connected inside the movable chamber 2112. The bottom surface of the pressing plate 304 contacts the top ends of the two locking blocks 302. Two fixing brackets 301 are fixedly connected to the upper surface of the rectangular block 2101. A spring-loaded timer 310 is threadedly connected to the inner wall of each fixing bracket 301. Each spring-loaded timer 310... Each of the 0's inner walls is rotatably connected to a long plate 309. Each of the fixed brackets 301's inner walls is fixedly connected to a second return spring 306. Each of the second return springs 306's bottom ends are fixedly connected to a pressing block 305. Each of the pressing blocks 305's upper surface is fixedly connected to a pressing shaft 307. Each of the pressing shafts 307's top ends are fixedly connected to a guide block 308. By setting a timing structure 3, a specified traction time can be set. When the traction time ends, the traction work on the jaw will automatically stop. By setting the installation unit 21, adjustment unit 22, and timing structure 3, the problem of poor wearing experience during use of the device can be effectively avoided.
[0036] The specific implementation of this embodiment is as follows: If timing of the traction time is required, simply apply rotational power to the long plate 309. The long plate 309 will drive the two spring-loaded timers 310 to rotate synchronously until the desired time is reached. At this time, the spring-loaded timers 310 store elastic potential energy to provide power for subsequent automatic reset. As time progresses, the spring-loaded timers 310 gradually release energy and reset, and the long plate 309 will rotate in the opposite direction. When it rotates above the guide block 308, the long plate 309 will squeeze the guide block 308. After being forced, the guide block 308 will drive the pressing shaft 307 to move downward. During the movement, the pressing shaft 307 will push the pressing block 305 to move downward synchronously, and the pressing block 305 will push the pressing plate 304 to move downward. The pressure of the pressing plate 304 will squeeze the locking block 302 into the interior of the rectangular block 2101 again. At this time, the limiting effect of the locking block 302 on the moving chamber 2112 is released. Due to the traction elastic band 2108... The device is always in a stretched state and stores elastic potential energy. After the limit of the locking block 302 is removed, the moving chamber 2112 will automatically reset under the pulling force of the traction elastic band 2108. When the moving chamber 2112 moves, it will drive the iron block 2107 and hook 2114 to move closer to the user's mouth until the traction elastic band 2108 returns to its natural relaxed state. At this time, the device will automatically release the traction on the mouth and jaw, avoiding damage to the jaw caused by excessive traction for a long time at night. After the user wakes up, he / she only needs to remove the device from the face and then manually push the moving chamber 2112 to reset. During the reset process, the user needs to apply a certain pushing force to the flip plate 2117 so that the flip plate 2117 overcomes gravity and sticks to the bottom surface of the moving chamber 2112, ensuring that all parts return to the initial position so that the installation and traction operation can be completed smoothly the next time it is used.
