Description

Technical Field

[0001] The present invention relates to a fish-shaped self-locking bracket, in particular to a fish-shaped self-locking bracket. Background Art

[0002] With the development of the times, the advancement of science and technology, and the improvement of manufacturing technology, more and more complex self-ligating bracket correction technologies have begun to be used in clinical practice.

[0003] At present, the self-ligating bracket widely used in domestic orthodontics is a semi-covered passive self-ligating bracket. The self-ligating bracket includes a bracket base, a bracket body installed on the bracket base, an arch wire placement slot provided on the bracket body, and a cover body provided on the bracket body. The bracket body is provided with a sliding groove perpendicular to the extension direction of the arch wire placement slot for sliding the cover body. In orthodontic treatment, a special adhesive is usually used to fix it on the tooth surface to accommodate and fix the orthodontic arch wire and transmit the correction force to the teeth, thereby achieving the effect of tooth correction. When it is necessary to open the arch wire placement slot, the cover body is slid away from the arch wire placement slot, and the arch wire placement slot will be opened at this time to facilitate the removal and installation of the arch wire; when it is necessary to close the arch wire placement slot, the cover body is slid and closed on the arch wire placement slot, and the arch wire placement slot will be closed at this time, ensuring the limiting effect of the cover body on the arch wire.

[0004] The invention patent with the patent number CN114521979B discloses a self-locking bracket with stable performance, which discloses that "the clamping structure includes a hole body 1, a transition groove and a hole body 2 which are sequentially opened at the bottom of the cover plate along the vertical direction of the arch wire placement slot, and the top of the self-locking main body is provided with a nickel-titanium tube slidably connected to the transition groove, and the nickel-titanium tube is located between two trapezoidal sliders", and "the cover plate 9 is slid and closed on the arch wire placement slot 3, and the nickel-titanium tube 6 enters the transition groove 11 from the hole body 2. With the relative displacement with the cover plate 9, the nickel-titanium tube 6 enters the hole body 10 through the transition groove 11, and the nickel-titanium tube 6 will return to its natural state and be confined in the hole body 10. At this time, the cover plate 9 closes the arch wire placement slot 3 and has sufficient locking force."

[0005] However, the above patent has the following defects: although the nickel-titanium tube can limit the cover plate, the use of the nickel-titanium tube to limit the cover plate will increase the force of pushing the cover plate due to the large friction in mechanical transmission. The tightening friction between the nickel-titanium tube and the inner wall of the transition groove will increase the force of pushing the cover plate and reduce the comfort of use. Summary of the Invention

[0006] In order to solve certain technical problems existing in the prior art, one of the purposes of the present application is to provide a fish-shaped self-locking bracket, which utilizes the lifting and lowering movement of the lifting limit column to achieve the limitation of the cover plate, avoids the use of the expansion of the nickel-titanium tube to limit the cover plate, and enables the cover plate to slide easily on the self-locking body.

[0007] In order to solve the above existing technical problems, one of the objectives of this application is achieved by adopting the following technical solutions:

[0008] A fish-shaped self-locking bracket comprises a self-locking base plate, a self-locking main body fixedly arranged on the self-locking base plate, an arch wire placement groove provided on the self-locking main body for placing an arch wire, and a cover plate slidably connected to the self-locking main body and used for limiting the arch wire. The top of the self-locking main body is provided with a lifting installation groove, and a lifting limit column is movably inserted in the lifting installation groove. The bottom of the cover plate is provided with a transition groove corresponding to the lifting limit column, and the lifting limit column can slide in the transition groove. The transition groove is also provided with an insertion hole, which can be used in conjunction with the lifting limit column. A lifting limit component is also provided in the lifting installation groove, and the lifting limit component can drive the lifting limit column to rise and fall, so that the lifting limit column is inserted into the insertion hole.

[0009] Furthermore, the lifting limit column is slidably connected to the lifting mounting slot, and the lifting limit assembly includes a rack fixedly arranged on the outer side wall of the lifting limit column, a rotating rod is provided between the lifting mounting slot and the outer side wall of the self-locking body, and a gear fixedly arranged on the rotating rod is provided in the lifting mounting slot, and the gear is engaged with the rack.

[0010] Furthermore, limiting grooves are provided on both the front and rear side walls of the lifting installation groove, and limiting blocks slidably connected to the limiting grooves are fixed on the lifting limiting columns.

[0011] Furthermore, a turntable is fixedly provided on the turning rod, a pin rod is passed through the turntable, a plurality of slots are opened on the self-locking body in the form of a circular array, and the plurality of limit slots are centered on the turning rod, and the pin rod can be inserted into the slots, a stop block is fixed on the pin rod, a limit spring is provided between the stop block and the turntable, and the limit spring is sleeved on the pin rod.

It should be understood that such terms are interchangeable where appropriate, allowing the embodiments of this application to be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first," "second," and so on generally refer to a class and do not limit the number of objects. For example, the first object can be one or more. Furthermore, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the connected objects, such as a fish-shaped self-ligating bracket. Example 1:

[0024] like Figure 1-Figure 5 As shown, this embodiment provides a fish-shaped self-locking bracket, which includes a self-locking base plate 1, a self-locking main body 2 fixedly arranged on the self-locking base plate 1, an arch wire placement groove 3 opened on the self-locking main body 2 for placing the arch wire, and a cover plate 7 slidably connected to the self-locking main body 2 and used for limiting the arch wire. A lifting installation groove 8 is opened on the top of the self-locking main body 2, and a lifting limit column 9 is movably inserted in the lifting installation groove 8. A transition groove 10 corresponding to the lifting limit column 9 is opened at the bottom of the cover plate 7. The lifting limit column 9 can slide in the transition groove 10. A socket 11 is also opened in the transition groove 10, and the socket 11 can be used in conjunction with the lifting limit column 9. A lifting limit component 22 is also provided in the lifting installation groove 8. The lifting limit component 22 can drive the lifting limit column 9 to rise and fall, thereby inserting the limit column into the socket 11.

[0025] When using the self-locking bracket, the arch wire is placed in the arch wire placement slot 3, the cover plate 7 is pushed to cover the arch wire, and then the lifting limit assembly 22 is operated. The lifting limit assembly 22 drives the lifting limit column 9 to move upward, so that the lifting limit column 9 is inserted into the insertion hole 11, thereby limiting the cover plate 7.

[0026] By cooperating with the lifting limit column 9 and the lifting limit assembly 22, the lifting movement of the lifting limit column 9 is utilized to limit the cover piece 7, avoiding the use of the expansion of the nickel-titanium tube to limit the cover piece 7, and enabling the cover piece 7 to slide easily on the self-locking main body 2. Compared with the existing brackets, this solves the technical problem that although the nickel-titanium tube can limit the cover piece 7, when the nickel-titanium tube is used to limit the cover piece 7, the friction between the nickel-titanium tube and the inner wall of the transition groove 10 in the mechanical transmission is large, which will increase the force to push the cover piece 7 and reduce the comfort of use.

[0027] The lifting limit column 9 is slidably connected to the lifting installation groove 8. The lifting limit assembly 22 includes a rack 13 fixedly arranged on the outer wall of the lifting limit column 9. A rotating rod 15 is provided between the lifting installation groove 8 and the outer wall of the self-locking body 2. A gear 14 fixedly arranged on the rotating rod 15 is provided in the lifting installation groove 8, and the gear 14 is engaged with the rack 13.

[0028] When using the lifting limit assembly 22, the rotating rod 15 is turned, the rotating rod 15 drives the gear 14 to rotate, the gear 14 drives the rack 13 to move upward, the rack 13 drives the lifting limit column 9 to move upward, and the lifting limit column 9 is inserted into the insertion hole 11 to limit the cover plate 7.

[0029] Limiting grooves 21 are provided on the front and rear side walls of the lifting installation groove. A limiting block 12 is fixedly provided on the lifting limiting column 9 and is slidably connected to the limiting groove 21. Through the cooperation of the limiting groove 21 and the limiting block 12, the lifting and lowering of the lifting limiting column 9 are limited and guided, which helps to make the lifting and lowering of the lifting limiting column 9 stable.

[0030] A turntable 17 is fixedly provided on the turning rod 15, and a pin rod 18 is passed through the turntable 17. A plurality of slots 16 are opened on the self-locking body 2 in the form of a ring array, and a plurality of limit grooves 21 are centered on the turning rod 15. The pin rod 18 can be inserted into the slot 16. A stopper 19 is fixed on the pin rod 18, and a limit spring 20 is provided between the stopper 19 and the turntable 17. The limit spring 20 is sleeved on the pin rod 18.

[0031] After the rotating rod 15 rotates to the appropriate position, the pin 18 is released, so that the pin 18 is inserted into the limiting groove 21, and the rotating disk 17 is positioned to prevent the rotating disk 17 and the rotating rod 15 from rotating again. By providing the limiting spring 20, the elasticity of the limiting spring 20 is utilized to limit the pin 18, so that the pin 18 can be stably inserted into the limiting groove 21.

[0032] Two trapezoidal slide grooves 6 are symmetrically provided at the bottom of the cover plate 7. A trapezoidal slider 5 is fixed on the top of the self-locking body 2 and is slidably connected to the trapezoidal slide groove 6. The cooperation between the trapezoidal slide groove 6 and the trapezoidal slider 5 limits the movement of the cover plate 7.

[0033] A fish-shaped protrusion 4 is provided between the top of the self-locking body 2 and the top of the cover plate 7, which helps to enhance the overall aesthetics of the self-locking bracket.

[0034] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
