[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the present utility model provides a technical solution: an orthodontic vertical closing device, including a buccal tube 1, a hook 2 for sleeving an arch wire is arranged at the lower end of the buccal tube 1, a chute 3 is opened at the lower part of one side of the buccal tube 1, a through port 4 is opened at the inner bottom of the chute 3, and the lower end of the through port 4 penetrates to the lower end of the buccal tube 1. A closing mechanism for closing the chute 3 is arranged at one end of the chute 3. A sliding member for horizontally sliding and adjusting the hook 2 is slidably arranged inside the chute 3, and a fixing mechanism for fixing the position of the hook 2 is arranged on the sliding member.

[0024] During use, by horizontally sliding the sliding member in the chute 3, the sliding member will drive the hook 2 to horizontally slide. When the hook 2 is horizontally slid and adjusted to a position suitable for conveniently sleeving the arch wire, the position of the hook 2 at this time is fixed by the fixing mechanism, and then the hook 2 can be used to sleeve the arch wire. Among them, by closing the chute 3 through the closing mechanism, it can prevent the sliding member from sliding out of the chute 3, thereby ensuring the stability of the sliding member during the sliding process in the chute 3, and at the same time, it can also prevent the hook 2 from falling off the buccal tube 1. Therefore, by horizontally sliding the sliding member in the chute 3, the sliding member can drive the hook 2 to horizontally slide, realizing the adjustment of the horizontal position of the hook 2 on the buccal tube 1, so that the hook 2 can be horizontally slid and adjusted to a suitable position according to the actual operation needs of the dentist to make it more convenient to sleeve the arch wire, and then the position of the hook 2 after adjustment is fixed by the fixing mechanism, ensuring the stability of the position of the hook 2, and then the hook 2 can be used to stably sleeve the arch wire, which is beneficial to the vertical correction process of the anterior and posterior inclined teeth, and solves the problem that the position of the hook 2 in the related technology is fixed and cannot be adjusted, making it inconvenient to use the hook 2 to sleeve the arch wire according to the actual operation needs of the dentist.

[0025] Refer to Figure 1 , Figure 2 and Figure 4 , the closing mechanism includes a closing opening 5, the closing opening 5 is opened at the lower part of one side of the buccal tube 1, and the closing opening 5 is communicated with the chute 3. A closing block 6 is arranged inside the closing opening 5. The closing opening 5 is of a threaded hole structure, the closing block 6 is of a threaded structure, and the closing block 6 is threadedly connected inside the closing opening 5. One end of the closing block 6 is fixedly connected with a limiting plate 7. The limiting plate 7 is of a circular structure, and the diameter of the limiting plate 7 is larger than the diameter of the closing block 6.

[0026] By screwing out the closing block 6 from the closing opening 5, the sliding member can be placed into the chute 3, which facilitates the placement of the sliding member. After placing the sliding member, by screwing the closing block 6 into the closing opening 5, the opening end of the chute 3 will be closed, thereby preventing the sliding member from sliding out of the chute 3.

[0027] Refer to Figure 3 and Figure 4, the sliding member includes a slider 8 which is slidably arranged in the chute 3. One end of the slider 8 is fixedly connected to a connecting rod 9, and the connecting rod 9 passes through the through opening 4. The hook 2 is fixedly connected to the lower end of the connecting rod 9. The connecting rod 9 is of an L-shaped structure, and the horizontal section of the connecting rod 9 is fixedly connected to the slider 8, and the vertical section of the connecting rod 9 is fixedly connected to the hook 2.

[0028] The fixing mechanism is arranged at the lower end of the slider 8.

[0029] After unscrewing the closing block 6 from the closing opening 5, the slider 8 can be placed into the chute 3, the connecting rod 9 will then enter the through opening 4, and the hook 2 will be located at the lower end of the buccal tube 1, thus completing the placement of the hook 2. At this time, by screwing the closing block 6 into the closing opening 5, the opening end of the chute 3 will be closed, thereby being able to prevent the slider 8 from sliding out of the chute 3 and also prevent the hook 2 from falling off the buccal tube 1.

[0030] Refer to Figure 3 and Figure 4 , the fixing mechanism includes a threaded rod 10. The upper end of the threaded rod 10 is fixedly connected to the lower end of the slider 8, and the threaded rod 10 passes through the through opening 4. The diameter of the threaded rod 10 is smaller than the width of the through opening 4, and the width of the through opening 4 is smaller than the width of the chute 3. The lower end of the threaded rod 10 extends below the through opening 4 and is threadedly connected to a tightening nut 11. The lower end of the tightening nut 11 is fixedly connected to a connecting plate 12.

[0031] By loosening the tightening nut 11, the slider 8 can slide in the chute 3, and the slider 8 will drive the hook 2 to slide horizontally through the connecting rod 9. When the hook 2 is horizontally slid and adjusted to a position suitable for conveniently sleeving the arch wire, by tightening the tightening nut 11, the slider 8 will be fastened and unable to slide, thereby fastening the position of the hook 2 at this time, and then the hook 2 can be used to sleeve the arch wire.

[0032] The working principle and usage process of the present utility model: When in use, first, by unscrewing the closing block 6 from the closing opening 5, the slider 8 is placed into the chute 3, the connecting rod 9 will then enter the through opening 4, and the hook 2 will be located at the lower end of the buccal tube 1, thus completing the placement of the hook 2. At this time, by screwing the closing block 6 into the closing opening 5, the opening end of the chute 3 will be closed, thereby being able to prevent the slider 8 from sliding out of the chute 3 and also prevent the hook 2 from falling off the buccal tube 1; then, by loosening the tightening nut 11, the slider 8 can slide in the chute 3, and the slider 8 will drive the hook 2 to slide horizontally through the connecting rod 9. When the hook 2 is horizontally slid and adjusted to a position suitable for conveniently sleeving the arch wire, by tightening the tightening nut 11, the slider 8 will be fastened and unable to slide, thereby fastening the position of the hook 2 at this time, and then the hook 2 can be used to sleeve the arch wire.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
