[0022] This utility model provides a double-tube flip-top type square wire bow with ring fixing device, the structure of which is as follows: Figures 1 to 5As shown in the accompanying drawings, the specific embodiments of this utility model will be described in detail below. The fixing body 1 is the core load-bearing component of the overall device. It has two parallel guide rail channels 2 inside, which extend along the length of the fixing body 1 to accommodate and guide the movement of the bowwire. The inner wall of the guide rail channel 2 is provided with a lubricating coating 12, made of polytetrafluoroethylene, covering the entire inner surface of the guide rail channel 2 to reduce friction between the bowwire and the guide rail channel 2. Guide slopes 13 are provided at both ends of the guide rail channel 2, extending outwards from the ends to form a smooth transition area, allowing the bowwire to smoothly enter the guide rail channel 2. A drain hole 17 is provided at the bottom of the fixing body 1, penetrating the inner and outer walls of the fixing body 1 to drain accumulated liquid or impurities from the guide rail channel 2. A filter screen 18 is provided inside the drain hole 17, embedded in and tightly fitted to the inner wall of the drain hole 17 to prevent external impurities from entering the guide rail channel 2.

[0023] The lifting cover component 3 is connected to the fixed body 1 via a hinge. The lifting cover component 3 includes a lifting cover plate 5 and a pressing block 6. One end of the lifting cover plate 5 is connected to the top of the fixed body 1 via a hinge, and the other end has a snap-fit ​​structure that cooperates with the bottom of the fixed body 1 to realize the opening and closing action of the lifting cover plate 5. The top of the lifting cover plate 5 has a pressing protrusion 14, which is located at the center of the outer surface of the lifting cover plate 5. Its surface has anti-slip particles to facilitate the operator to apply pressing pressure. The bottom of the lifting cover plate 5 has a return spring 15, one end of which is fixed to the inner side of the bottom of the lifting cover plate 5, and the other end is fixed to the inner wall of the fixed body 1, for automatic reset after the lifting cover plate 5 is opened. The pressing block 6 is fixed to the inner side of the lifting cover plate 5 near the middle of the lifting cover plate 5. The bottom surface of the pressing block 6 has raised stripes that are distributed along the length of the pressing block 6 to enhance the pressing effect.

[0024] The clamping component 4 includes two symmetrically arranged clamping pieces 7, located inside the fixing body 1 and corresponding to the position of the guide rail channel 2. The inner side of each clamping piece 7 has an arc-shaped groove 8 extending along its length, and its surface is covered with a flexible pad 9 made of silicone material, covering the entire inner surface of the arc-shaped groove 8. The two clamping pieces 7 are connected by an elastic connector 10, one end of which is fixed to the outer side of the clamping piece 7, and the other end is fixed to the inner wall of the fixing body 1, allowing the clamping pieces 7 to elastically open or close within a certain range. The outer side of each clamping piece 7 has a positioning groove 16, distributed along its length, and its shape matches the raised stripes of the pressure block 6. The depth of the positioning groove 16 is slightly greater than the height of the raised stripes to prevent deformation of the clamping piece 7 due to excessive pressure. When the cover lifting component 3 is in the closed state, the cover lifting plate 5 drives the clamping block 6 to move downward. The raised stripes of the clamping block 6 act on the outer positioning groove 16 of the clamping piece 7, causing the clamping piece 7 to retract inward, thereby clamping the archwire in the arc-shaped groove 8. When the cover lifting component 3 is in the open state, the clamping piece 7 automatically opens under the action of the elastic connector 10, releasing the archwire.

[0025] The fixing body 1 has mounting ears 11 on both sides, which are located on the outer side of the fixing body 1 and symmetrically distributed. The mounting ears 11 have threaded holes inside, which extend through the thickness direction of the mounting ears 11, for threaded connection with the mounting post of the tooth bracket. The outer side of the mounting ears 11 has anti-slip texture, which is distributed along the surface of the mounting ears 11 to allow the operator to apply torque during installation or removal.

[0026] The operation of this utility model is as follows: During use, the fixing body 1 is first threadedly connected to the mounting post of the tooth bracket via the mounting ear 11 to ensure a secure fixation. Then, the bowwire is inserted from one end of the guide rail channel 2, and the guide ramps 13 at both ends of the guide rail channel 2 guide the bowwire smoothly into the guide rail channel 2. When it is necessary to fix the bowwire, the operator presses the pressing protrusion 14 on the cover plate 5, causing the cover plate 5 to rotate downwards around the hinge. The cover plate 5 drives the clamping block 6 to move downwards. The raised stripes of the clamping block 6 act on the outer positioning groove 16 of the clamping piece 7, causing the clamping piece 7 to retract inwards. The arc-shaped groove 8 of the clamping piece 7 clamps the bowwire, thus achieving stable fixation of the bowwire. When it is necessary to adjust or release the bowwire, the operator lifts the cover plate 5 upwards, causing the cover plate 5 to rotate upwards around the hinge. The clamping block 6 disengages from the outer positioning groove 16 of the clamping piece 7, and the clamping piece 7 automatically opens under the action of the elastic connector 10, releasing the bowwire. After the cover plate 5 is opened, the return spring 15 pushes the cover plate 5 to automatically return to its original position. During use, any accumulated liquid or impurities in the guide rail channel 2 can be discharged through the drain hole 17, and the filter screen 18 prevents external impurities from entering the guide rail channel 2, ensuring the normal operation of the device.

[0027] This invention achieves rapid fixing and flexible adjustment of the archwire through the above-described structural design, simplifying the overall structure, reducing the number of parts, and lowering manufacturing costs. Simultaneously, the design of the lubricating coating 12 and the flexible pad 9 effectively reduces friction between the archwire and the device, improving correction efficiency. The hinged design of the flip-top component 3 and the cooperation of the return spring 15 make operation more convenient. The elastic connector 10 and positioning groove 16 of the clamp 7 ensure the stability of the clamp 4 in the working state, avoiding loosening or wear problems caused by long-term use. The mounting ears 11 and anti-slip texture design on both sides of the fixing body 1 enhance the connection strength between the device and the dental bracket, facilitating installation and disassembly by operators. The guide slopes 13 at both ends of the guide rail channel 2 and the drainage holes 17 at the bottom further enhance the practicality and durability of the device, solving the problems of increased friction and shortened service life caused by structural limitations in the prior art.

[0028] To enable those skilled in the art to fully understand and implement this utility model, the following detailed explanation of its operating principle and implementation method is provided in conjunction with specific application scenarios.

[0029] When using this device, the fixing body 1 is first threadedly connected to the mounting post of the dental bracket via the mounting ear 11. The threaded hole inside the mounting ear 11 ensures a secure connection between the fixing body 1 and the dental bracket, while the anti-slip texture on the outside of the mounting ear 11 facilitates the operator to apply torque, thus completing the initial installation of the device. This step achieves a stable connection between the device and the dental bracket through mechanical connection, providing a reliable foundation for subsequent adjustment and fixation of the archwire.

[0030] Subsequently, the bowwire is inserted from one end of the guide channel 2. The guide ramps 13 at both ends of the guide channel 2 play a crucial guiding role; their inclined design allows the bowwire to enter the guide channel 2 smoothly, avoiding jamming or damage caused by improper angle. The lubricating coating 12 on the inner wall of the guide channel 2 is made of polytetrafluoroethylene (PTFE) and covers the entire inner surface, further reducing the friction between the bowwire and the guide channel 2. This low-friction environment not only improves the bowwire's movement efficiency but also reduces the risk of wear caused by friction, thereby extending the device's service life.

[0031] When the archwire needs to be secured, the operator presses the pressing protrusion 14 on the cover plate 5, causing the cover plate 5 to rotate downwards around the hinge. A return spring 15 is located at the bottom of the cover plate 5, one end of which is fixed to the inner side of the bottom of the cover plate 5, and the other end is fixed to the inner wall of the fixing body 1. During the downward rotation of the cover plate 5, the return spring 15 is compressed, and simultaneously, the cover plate 5 drives the clamping block 6 to move downwards. The raised stripes on the bottom surface of the clamping block 6 cooperate with the positioning groove 16 on the outer side of the clamping piece 7. When the clamping block 6 applies downward pressure, its raised stripes act on the positioning groove 16, causing the clamping piece 7 to retract inwards. The surface of the arc-shaped groove 8 on the inner side of the clamping piece 7 is covered with a flexible pad 9, made of silicone material, which provides a cushioning effect while clamping the archwire, preventing damage to the archwire surface due to over-clamping. Furthermore, the design of the arc-shaped groove 8 matches the shape of the archwire, further improving the stability of the clamping.

[0032] When it is necessary to adjust or release the bowwire, the operator lifts the cover plate 5 upwards. The cover plate 5 rotates upwards around the hinge, and the clamping block 6 disengages from the outer positioning groove 16 of the clamping piece 7. At this time, the clamping piece 7 automatically opens under the action of the elastic connector 10, releasing the bowwire. One end of the elastic connector 10 is fixed to the outer side of the clamping piece 7, and the other end is fixed to the inner wall of the fixing body 1. Its elastic characteristics ensure that the clamping piece 7 can return to its initial state without external force, thereby realizing the rapid release of the bowwire. After the cover plate 5 is opened, the return spring 15 pushes the cover plate 5 to automatically return to its original position, preparing for the next operation.

[0033] During long-term use, liquid or impurities may accumulate inside the guide rail channel 2, affecting the normal operation of the device. To address this, a drain hole 17 is provided at the bottom of the fixing body 1, penetrating both the inner and outer walls of the fixing body 1, to drain accumulated liquid or impurities from the guide rail channel 2. A filter screen 18 is embedded inside the drain hole 17, fitting tightly to prevent external impurities from entering the guide rail channel 2, thus maintaining its cleanliness and unobstructed flow. This design effectively solves the liquid accumulation problem caused by structural limitations in existing technologies, further enhancing the practicality of the device.

[0034] Through the above steps, this invention achieves rapid fixing and flexible adjustment of the archwire. The design of the dual guide rail channel 2 allows the archwire to move freely in two independent channels, while the opening and closing action of the cover component 3 enables convenient fixing and release of the archwire. The introduction of the lubricating coating 12 and the flexible pad 9 significantly reduces the friction between the archwire and the device, improving correction efficiency. At the same time, the hinged design of the cover component 3, in conjunction with the return spring 15, simplifies the operation process, and the design of the elastic connector 10 and the positioning groove 16 of the clamp 7 ensures the stability of the clamp 4 in the working state, avoiding loosening or wear problems caused by long-term use. The mounting ears 11 and anti-slip texture design on both sides of the fixing body 1 enhance the connection strength between the device and the dental bracket, facilitating installation and disassembly by the operator. The guide slopes 13 at both ends of the guide rail channel 2 and the drainage holes 17 at the bottom further enhance the practicality and durability of the device, solving the problems of increased friction and shortened service life caused by structural limitations in the prior art.

[0035] In summary, through its reasonable structural design and functional configuration, this invention not only simplifies the operation process but also significantly improves the performance and reliability of the device, providing a more efficient and stable solution for orthodontic treatment.
