[0018] In the utility model, the cooperation of the plurality of anti-skid sleeve rings increases the contact area of the outer wall of the outer rubber ring, thereby increasing the friction force between the overall and the invisible orthodontic appliance, which helps the overall tooth traction correction cooperation.

[0019] Compared with the prior art, the utility model has the advantages of:

[0020] 1. The utility model discloses an outer rubber ring with a circular groove, an inner traction ring with a storage groove is plugged into the circular groove, the overall structural stability is increased, and the reinforcing rib is further plugged into the storage groove, the overall toughness is increased, and the overall is prevented from being broken due to long-term use, thereby affecting the invisible orthodontic appliance position traction fixing cooperation.

[0021] 2. The utility model discloses a plurality of anti-skid sleeve rings, which increase the contact area of the outer rubber ring, thereby increasing the friction force between the outer rubber ring and the invisible orthodontic appliance, realizing the correction treatment cooperation of the teeth, and being convenient to assemble and having a long service life.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This embodiment provides a technical solution:

[0032] An elastic traction ring for invisible orthodontic appliances includes an outer rubber ring 1, and the outer rubber ring 1 is provided with an inner traction ring 2 and a reinforcing rib 3 from the outside to the inside.

[0033] Among them, invisible orthodontic appliances are devices for treating malocclusion, or orthodontic appliances. They can generate force to promote the normal growth and development of the dentofacial region.

[0034] Furthermore, the outer rubber ring 1 is circular, and a circular groove 10 is provided at the center of the outer rubber ring 1.

[0035] In this invention, the outer rubber ring 1 is made of natural rubber, which is elastic, plastic, and has good alkali resistance, making it easier to fit onto the orthodontic appliance for tooth traction.

[0036] Specifically, the inner diameter of the circular groove 10 is matched with the outer diameter of the inner traction ring 2, and the inner traction ring 2 is circular.

[0037] In this invention, the circular groove 10 facilitates the insertion and installation of the inner traction ring 2, and the inner traction ring 2 increases the structural toughness of the outer rubber ring 1, thereby increasing the overall structural stability.

[0038] It should be noted that a storage slot 20 is provided at the center of the inner traction ring 2.

[0039] In this invention, the storage slot 20 facilitates the insertion and installation of the reinforcing rib 3.

[0040] Furthermore, the inner diameter of the storage slot 20 is matched with the outer diameter of the reinforcing rib 3, and the reinforcing rib 3 is arc-shaped.

[0041] In this invention, the reinforcing rib 3 is made of polyester-methylene material, which increases the overall toughness and extends the overall service life. Furthermore, the reinforcing rib 3 is inserted into the storage slot 20, reducing the overall area occupied.

[0042] Specifically, the outer wall of the outer rubber ring 1 is provided with several anti-slip rings 11, which are distributed at equal intervals and are bonded and fixed to the outer rubber ring 1.

[0043] In this invention, the cooperation of multiple anti-slip rings 11 increases the contact area of ​​the outer wall of the outer rubber ring 1, thereby increasing the friction between the whole and the invisible orthodontic appliance, which helps the whole to perform tooth traction and correction.

[0044] When using the elastic traction ring of the invisible orthodontic appliance in this embodiment, the user first installs the reinforcing rib 3 in the storage slot 20, the inner traction ring 2 in the circular slot 10, and the outer rubber ring 1 wraps the inner traction ring 2 and the reinforcing rib 3 to increase the toughness of the overall structure. Multiple anti-slip rings 11 are also fitted on the outer wall of the outer rubber ring 1 to increase the overall external contact area, thereby increasing the ability to combine and install with the orthodontic appliance.

[0045] When orthodontic treatment is required, the outer rubber ring 1 is engaged with the corresponding connector to increase the pulling force on the teeth. With the cooperation of the outer rubber ring 1, the inner traction ring 2 and the reinforcing rib 3, the overall tensile strength is increased and the impact of breakage is reduced. With the cooperation of the anti-slip ring 11, the friction with the orthodontic appliance is increased, thereby increasing the stability of the installation.
