Detailed Description

For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.

According to an embodiment of the present invention, a rotatable orthodontic bracket is provided.

The first embodiment is as follows:

as shown in fig. 1-4, the rotatable orthodontic bracket according to the embodiment of the present invention comprises a base 1 and a tooth 2, wherein the base 1 is located on one side of the surface of the tooth 2, a bracket body 3 is arranged in the middle of the base 1, a plurality of fins 4 are arranged on the surface of the bracket body 3, a working groove is formed between the fins 4, a rotating base 5 is arranged between the base 1 and the bracket body 3, a circular groove 6 is arranged at one end of the rotating base 5 close to the bracket body 3, a connecting shaft 7 is arranged between the rotating base 5 and the bracket and located in the middle of the circular groove 6, a rotating disc 8 connected with the bracket body 3 is arranged in the middle of the connecting shaft 7, a plurality of rotating inclined teeth 9 are arranged on the rotating disc 8, an open slot 10 is arranged at one side of the inside of the rotating base 5 close to the circular groove 6, a locking connecting rod 11 is arranged in the middle of the open slot, the lower end of the locking connecting rod 11 is sleeved with an inclined rod 12 matched with the rotating inclined teeth 9, one side of the lower portion of the locking connecting rod 11 is provided with an adjusting rod 13, and an elastic shifting piece 14 is arranged between the adjusting rod 13 and the inclined rod 12.

Example two:

as shown in FIGS. 1 to 4, the base 1 is connected to the tooth 2 by enamel bonding 15. the base 1 has a plurality of protrusions 16 spaced apart from each other at one end of the tooth 2, and a plurality of gully-shaped grooves 17 are formed between the protrusions 16. the number of the flaps 4 is four, and the flaps 4 are L.

As shown in fig. 1-4, one side of the oblique rotation teeth 9 is provided with a connecting tooth 18, and one end of the oblique rod 12 located at the oblique rotation teeth 9 is provided with a latch 19 matched with the connecting tooth 18. A spring 20 is arranged between the elastic poking sheet 14 and the inclined rod.

For the convenience of understanding the technical solution of the present invention, the following detailed description is made on the working principle or the operation mode of the present invention in the practical process.

In practical application, the base 1 and the teeth 2 form a binding force through the enamel bonding glue 15, so that the orthodontic bracket has enough bonding force to resist orthodontic force and chewing force, compared with an orthodontic bracket which is only bonded by the tongue side surface of the base 1, the risk of falling off from the tooth surface of the teeth 2 is greatly reduced, meanwhile, the enamel bonding glue 15 and the convex particles 16 and the gully-shaped grooves 17 on the base 1 further facilitate the inflow of the bonding glue and enhance the bonding fixing force, before bonding is used, the locking connecting rod 11 is pulled out, the adjusting rod 13 is rotated to loosen the elastic shifting piece 14, the rotating seat 5 is rotated to the inclined rod 12 to drive the connected rotating disc 8 and the rotating inclined teeth 9 to rotate, after an angle is determined, the two convex blocks of the locking connecting rod 11 are clamped with the inclined rod 12 to make the bracket body 3 immovable, and when the traction angle needs to be adjusted, the locking connecting rod 11 is opened, the direction of the groove of the rotating oblique teeth 9 of the bracket body 3 can be directly adjusted by rotating the rotating seat 5, so that the angle between the direction of the traction force and the long axis of the teeth is changed, the orthodontic bracket is more convenient and firmer to apply, and the efficiency of straightening the teeth 2 is improved.

To sum up, with the aid of the above-mentioned technical scheme of the utility model, bond through enamel and glue 15 and form cohesion with base 1 and tooth 2, thereby make just abnormal support groove have sufficient cohesive force in order to resist just abnormal power and masticatory force, compare the just abnormal support groove that relies on the bonding of 1 tongue side of base alone, the risk greatly reduced who drops on 2 tooth surfaces of follow tooth, through the rotation to supporting the cell body 3, make just abnormal support groove execute do more convenient, it is more firm, and then can improve 2 orthodontic appliances of tooth 2's the efficiency of correcting tooth, can shorten the traction time in the at utmost, improve and correct efficiency, reduce patient's misery, consequently, good application prospect has.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
