Embodiment 1

[0041] Such as Figure 1 to Figure 5 As shown, this embodiment provides a double slide type self-locking bracket.

[0042] The double-door sliding-plate self-locking bracket includes a bottom plate 10 and a bracket body 11 arranged on the bottom plate 10. The bracket body 11 is provided with an archwire groove 12, and the width of the archwire groove 12 is 2mm-10mm, Working wings 20 are provided on both sides of the archwire groove 12, the working wings 20 and the bracket bodies 11 on both sides of the archwire groove 12 enclose a first sliding cavity 21, and the first sliding cavity 21 is in communication with the archwire groove 12 , The first sliding cavity 21 is provided with a rebound piece 22 and a sliding plate 23, the sliding plates 23 on both sides conflict with each other to close the archwire groove 12 above the archwire groove 12 or slide open to both sides of the archwire groove 12 The archwire groove 12; the sliding plate 23 is provided with a hook 24, when the arch...

Embodiment 2

[0056] The difference between this embodiment and the first embodiment is that the stroke groove 35, the slot 34, and the elastic blocking post 33 are omitted, and a spring or spring assembly is provided at the bottom of the first sliding cavity 21. In the process of closing the archwire groove 12, after the hook 24 is disengaged from the buckle, the squeezed spring or spring assembly is used to drive the sliding plate 23 and the hook 24 back to position, thereby replacing the function of the elastic blocking post 33.

Embodiment 3

[0058] Such as Figure 6 to Figure 9 As shown, the difference between this embodiment and embodiment 1 is that the self-locking bracket is a self-locking bracket with a double-door sliding plate of the card slot, which includes a bottom plate 10 and a bracket body 11 arranged on the bottom plate 10, and the bracket body 11 An archwire groove 12 is provided on the upper part, and the bracket body 11 on both sides of the archwire groove 12 is provided with a working wing 20. A first sliding cavity 21 is enclosed between the working wing 20 and the bracket body 11. 21 is connected to the archwire groove 12, and the first sliding cavity 21 on both sides of the archwire groove 12 is provided with elastic sliding plates 23, and the sliding plates 23 on both sides conflict with each other to close the archwire groove 12 above. The groove 12 or sliding to both sides of the archwire groove 12 to open the archwire groove 12; the first sliding cavity 21 is provided with a first clamping po...

Abstract

The invention relates to the field of devices for tooth correction and discloses an orthodontic bracing device adopting a structure of double doors. The device comprises a self-locking bracket and anoperation tool, wherein working wings (20) are arranged on two sides of an arch wire groove (12) and define first sliding cavities (21) with a bracket body (11) on the two sides of the arch wire groove (12), the first sliding cavities (21) are communicated with the arch wire groove (12), sliding plates (23) are arranged in the first sliding cavities (21), operation notches (30) are formed in one side, away from the arch wire groove (12), of each working wing (20) from top to bottom, the operation notches (30) penetrate through upper end surfaces and lower end surfaces of the first sliding cavities (21) to form communicating ports (31), the sliding plates (23) on two sides are propped against the upper side of the arch wire groove (12) to close the arch wire groove (12) or slide towards twosides of the arch wire groove (12) to open the arch wire groove (12). The device has the advantages that opening is convenient, wire placement is convenient, the operation efficiency is high, the fault rate is low, the structure is simple and reliable and the like.

Description

Technical field [0001] The invention relates to the field of orthodontic brackets, in particular to an orthodontic device with a double-door structure. Background technique [0002] At present, in the process of orthodontic treatment of oral teeth, orthodontic brackets are fixed on the tooth surface, and the arch wire is passed through the arch wire groove (also known as the square wire groove) on the bracket, and the rubber ring or ligature wire is ligated The steel wire ligates the arch wire directly into the groove of the arch wire of the bracket, and the correcting force of the arch wire is transmitted to the teeth through the bracket, so that the teeth can move as expected to achieve the purpose of correcting the teeth. Due to the currently used ligation rubber ring or ligation wire ligation and the ligation wing of the bracket, the direct application of force to the arch wire produces a greater pressure on the arch wire, which hinders the normal movement of the arch wire, t...
