Description

Technical Field

[0001] The invention relates to the field of tooth correction, and in particular to a lateral locking and non-reversing self-locking appliance. Background Art

[0002] Patent CN2019209043316 provides a passive dental appliance, which mainly includes two major components: a bracket body (numbered 2 in the figure in the document) and a locking plate (numbered 1 in the figure in the document), wherein the locking plate is slidably mounted on the bracket body. In order to prevent the locking plate from slipping out of the bracket body, the appliance of this structure is provided with a mounting groove (numbered 201 in the figure in the document) in the bracket body, and a straight slide (numbered 101 in the figure in the document), an arc positioning slide (numbered 102 in the figure in the document) and a guide slide (numbered 103 in the figure in the document) are arranged on the locking plate, and then an elastic clip (numbered 5 in the figure in the document) is used to prevent the locking plate from slipping off the bracket body. Therefore, this structure causes greater wear on the elastic clip during use, is easy to slip, and has low reliability. Summary of the invention

[0003] In view of the above problems, the present invention proposes a lateral locking and anti-reverse self-locking orthodontic appliance.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A lateral locking and anti-reverse self-locking orthodontic appliance comprises a base and a locking plate, wherein the locking plate is slidably mounted on the base, a limiting groove is arranged on the locking plate, a through hole is opened on the base, a limiting member is arranged on the through hole, and the limiting member is located in the limiting groove.

[0006] In this structure, a limiting groove is provided on the locking plate, and a limiting member is provided on the base, and the limiting member is located in the limiting groove. Thus, the limiting member plays a limiting role on the limiting groove, and can prevent the locking plate from slipping off the base. The structure is simple and reliable, and the processing is convenient.

[0007] Optionally, the limiting member is a limiting plate, and the limiting plate is located at the opening of the through hole, and the limiting plate is integrally formed with the base.

[0008] When a limiting piece is used, when processing a through hole, only a thin piece (i.e., a limiting piece) needs to be left at an opening of the through hole. When the locking piece is inserted into the base, an object is used to direct the thin piece toward the limiting groove, so that part of the thin piece can be pushed out of the through hole, and the thin piece thus plays the role of a limiting piece. In this way, the limiting piece is realized by using part of the material of the base itself, the structure is reliable, and the processing cost is low.

[0009] Optionally, the limiting member is a pin, and the pin is clamped in the through hole, with one end of the pin located in the limiting groove.

[0010] This is another way to implement a limiter.

[0011] Optionally, it further comprises a ligation wing, wherein the ligation wing is arranged on the base, a slide groove is formed between the ligation wing and the base, and the locking piece is slidably arranged in the slide groove.

[0012] Optionally, the base and the locking plate are provided with a limiting protrusion and a limiting recess that can cooperate with each other.

[0013] Optionally, a mounting groove is provided on the base, a slideway is provided on the locking plate, a V-shaped or U-shaped elastic snap-fitting part is provided in the mounting groove, and the elastic snap-fitting part is slidably matched with the slideway.

[0014] The purpose of still setting the elastic snap fastener is to make the locking plate more stable when sliding. At the same time, because the locking plate and the base rely on the cooperation between the limiting groove and the limiting member to prevent slipping, there is no requirement for the structure of the slide.

[0015] Optionally, a round ball is further included, a countersunk hole is opened on the base, the round ball is elastically installed in the countersunk hole through a spring or silicone, and a round pit matching with the round ball is provided on the locking plate.

[0016] The beneficial effects of the present invention are as follows: by arranging a limiting groove on the locking plate and arranging a limiting member on the base, and the limiting member is located in the limiting groove, the limiting member plays a limiting role on the limiting groove, and can prevent the locking plate from slipping off the base. The structure is simple and reliable, and the processing is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
