specific Embodiment 1

[0050] Such as Figure 1-6 As shown, the elastic member 300 is in an "S" shape, and the locking protrusion 310 at the locking end is a smooth protrusion. At the bottom of 300, the locking protrusion 310 is tilted up relative to the positioning end 330, and the two neutral positions of the transition part 320 of the "S"-shaped elastic member 300 are the first avoidance position 340 and the second avoidance position 350 from top to bottom. The elastic member 300 is installed in the avoidance cavity 111 of the main body 100, so that the positioning end 330 is in contact with the bottom of the avoidance cavity 111, and the locking protrusion 310 protrudes from the avoidance cavity.

[0051] After the elastic member 300 is installed in the avoidance cavity 111 of the main body 100, the cover body 200 is installed again. The slide rail and the guide rail of the cover body 200 respectively slide and push the cover body 200 along the chute 114 and the guide groove 113 of the main body...

specific Embodiment 2

[0057] Such as Figure 7-8 As shown, the positioning end 330 of the elastic member 300 is a flat plate, and the locking end is a tilt at one end of the positioning end. 180°, wherein the most preferred range is 30°-60°. The elastic member 300 is in a “T” shape, and the locking end of the elastic member 300 can be pressed to move the locking end downward.

[0058] It should be noted that the range of angles mentioned here is only used to describe the magnitude of the warp, without any specific limitation.

[0059] The principle of this embodiment is the same as that of the first embodiment, and will not be repeated here.

specific Embodiment 3

[0061] Such as Figure 9-10 As shown, the elastic member 300 is in the shape of a question mark as a whole, and the locking end is approximately in the shape of a "U" or "V". connected so that the elastic member 300 is in the shape of a "question mark". The escape cavity 111 of the main body 100 matched with the elastic member 300 is an inverted "h"-shaped cavity. When the locking end is squeezed, the locking protrusion 310 bends toward the groove bottom of the avoiding cavity 111, and the first avoiding position The 340 position is narrowed. The elastic member 300 is matched with the avoidance cavity 111 on the main body 100 , and there is a groove under the avoidance cavity 111 matching the positioning end 330 of the elastic member 300 for assembling the positioning end 330 .

[0062] The principle of this embodiment is the same as that of the first embodiment, and will not be repeated here.

Abstract

A self-locking orthodontic bracket is disclosed. The self-locking orthodontic bracket is characterized in that the bracket includes an elastic member, a main body and a cover; the elastic member includes a blocking end and a positioning end integrated with the blocking end; the cover and the main body are in a sliding fit; the cover is provided with a slide cavity corresponding to the blocking end; the self-locking orthodontic bracket has gears including an unlocking gear and a closing gear; the cover body is switched between the unlocking gear and the closing gear through sliding of the cover; the main body is provided with an avoidance chamber in which the positioning end is disposed; and when the cover slides to achieve switching between the gear states, the blocking end elastically deforms towards the avoidance chamber. The self-locking orthodontic bracket consists of the main body, the cover matching the main body and the elastic member matching the main body. Through action of the elastic member, the structure of the self-locking orthodontic bracket is stabilized, the cover is prevented from falling down from the main body and the structure is firmer.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a shrapnel type self-locking orthodontic bracket. Background technique [0002] Brackets are an important part of orthodontic correction. During traditional orthodontic treatment, the orthodontist sticks the brackets on the patient's teeth and places the archwires in the archwire grooves of the brackets. The tooth exerts force to move the tooth into the correct position. But the traditional bracket has no specific limit to the arch wire, only auxiliary tools such as ligature wire can be used to bind the ligature wings of the bracket, so that the arch wire remains in the bracket. However, due to the small size of the bracket, it is difficult for orthodontists to apply the ligature wire. Nowadays, self-locking brackets have been developed, which keep the archwire in the archwire groove of the bracket by relying on the movement of the bolt or cover. among them, thereby eliminating the ...
