AI Technical Summary
The existing self-ligating orthodontic brackets have an unreasonable elastic component structure design, resulting in a short lifespan and easy damage or weakening of elasticity.
A self-locking orthodontic bracket is designed, employing an elastic element with first and second elastic arms. The first elastic arm is used for sliding cover shifting, and the second elastic arm is used to prevent the sliding cover from detaching. Through the smooth transition of the slot segment junction and the blocking wall structure, the force is distributed, avoiding localized concentrated force.
It improves the lifespan of self-locking orthodontic brackets, enhances the stability and ease of operation of sliding covers, reduces chairside time, lowers costs, and improves user experience and cleanliness.

Abstract
Claims
1. A self-locking orthodontic bracket, comprising a bracket body and a sliding cover, the bracket body is provided with a sliding groove and an archwire groove, the sliding cover is movably installed in the sliding groove to realize opening and closing of the archwire groove, the sliding cover has a first position for closing the archwire groove and a second position for opening the archwire groove, characterized in that, The bottom surface of the sliding cover is provided with a stop groove, which has a first groove section and a second groove section that are connected. The second groove section is located at the end of the first groove section away from the bow wire groove, and the groove depth of the first groove section is less than the groove depth of the second groove section. The bottom of the chute is provided with a receiving hole, and an elastic element is installed in the receiving hole. The elastic element has a first elastic arm and a second elastic arm. The upper ends of the first elastic arm and the upper ends of the second elastic arm both extend out of the receiving hole and into the stop groove. The second elastic arm is located on the side of the first elastic arm facing away from the bow wire groove. The length of the first elastic arm extending out of the receiving hole is greater than the groove depth of the first groove segment. The junction of the first groove segment and the second groove segment cooperates with the second elastic arm to realize the sliding cover shifting. The side of the first elastic arm facing away from the second groove segment cooperates with the groove wall of the first groove segment to prevent the sliding cover from detaching from the bracket body.
2. The self-ligating orthodontic bracket of claim 1, wherein, The first groove section has a first blocking wall, and the first elastic arm has a second blocking wall that is parallel to and opposite to the first blocking wall. Both the first blocking wall and the second blocking wall are perpendicular to the sliding direction of the sliding cover. When the first blocking wall and the second blocking wall are in contact, the sliding cover is limited.
3. The self-ligating orthodontic bracket of claim 1, wherein, The junction of the first and second groove segments is smoothly transitioned, and the upper end of the second elastic arm, opposite to the junction of the first and second groove segments, is set as a curved surface or an inclined surface.
