Description

Technical Field

[0001] The present invention relates to the field of dental medicine, and in particular to a flip-type self-locking bracket. Background Art

[0002] Brackets are an essential component of fixed orthodontic appliances, used to transmit corrective force to the teeth and move them into the correct position. Traditional brackets typically require ligatures or rubber bands to secure the archwire within the bracket, a cumbersome process. This led to the development of flip-top, self-ligating brackets.

[0003] The existing flip-top self-locking bracket has a hinged cover on one end and fixed to the bracket body on the other end by a latch. However, since the bracket itself is a relatively small object, when the flip-top needs to be opened during treatment, it is necessary to use tweezers or other tools to pull out the latch, which is difficult to operate and can easily cause the latch to fall into the patient's mouth, affecting the progress of treatment. Summary of the Invention

[0004] In order to improve the convenience of operation and enhance the efficiency of treatment, the present application provides a flip-top self-locking bracket.

[0005] This application provides a flip-top self-locking bracket, which adopts the following technical solution:

[0006] A flip-type self-locking bracket comprises a bracket body and a flip cover, the bracket body is provided with an archwire slot; the flip cover is provided on the side of the bracket body where the archwire slot is provided, one end of the flip cover is hinged to the bracket body and is located on one side of the archwire slot, and the other end is provided with a plug-in block, the bracket body is located on the other side of the archwire slot and is provided with a plug-in slot for inserting the plug-in block; the bracket body is located in the plug-in slot and an axis wire is installed in the plug-in slot, the plug-in block is provided with an arc-shaped protrusion at the end away from the flip cover, and a limiting groove for the axis wire to be clamped into is formed between the arc-shaped protrusion and the flip cover; when the plug-in block is inserted into the plug-in slot, the axis wire is clamped in the limiting groove.

[0007] By adopting the above technical solution, after the arch wire is inserted into the arch wire slot, the unlocking tool is used to move the flip cover and rotate it until the plug-in block is initially inserted into the plug-in slot, and then the unlocking tool is used to press the front of the flip cover. During the process, the arc surface of the arc-shaped protrusion and the elasticity of the axis wire enable the axis wire to be smoothly inserted into the limit slot, thereby completing the locking of the flip cover. In this process, the flip cover can be locked by simply rotating and pressing the flip cover, without the need to use other components for locking. The operation is convenient, thereby improving the treatment efficiency.

[0008] Preferably, a plurality of arc-shaped protrusions are arranged at intervals along the length direction of the axial wire.

[0009] By adopting the above technical solution, the arch wire can be inserted into more limiting grooves, thereby making the flip cover connection more stable.

[0010] Preferably, a through slot is provided on a side of the insertion slot away from the archwire slot, and the through slot extends out of the bracket body; a toggle block is installed on one end of the flip cover away from the hinge, and the toggle block is clamped to the bracket body through the through slot.

[0011] By adopting the above technical solution, an unlocking tool is inserted into the through slot, and then the toggle block is pried with a little force, so that the flip cover can be rotated along the hinge axis until the plug-in block leaves the plug-in slot, thereby completing the opening of the arch wire slot and installing or replacing the arch wire.

[0012] Preferably, a toggle groove is formed on one side of the toggle block facing the through groove.

[0013] By adopting the above technical solution, the toggle groove is provided, so that the unlocking tool can pry the toggle block more stably.

[0014] Preferably, the flip cover is located between the toggle block and the hinge as a covering portion, and the covering portion is as wide as the bracket body.

[0015] By adopting the above technical solution, the flip cover can cover the archwire slot more fully, making the archwire more stable in the archwire slot, which is conducive to fully expressing the axis inclination angle.

[0016] Preferably, the bracket body includes a main body and a pair of lower wings, and the two lower wings are installed at intervals on the side of the main body where the archwire slot is opened in the length direction of the archwire slot, and a hinge groove is formed between the two lower wings, and the flip cover is hinged in the hinge groove; the edge of the main body away from one end of the plug-in slot and the position corresponding to the hinge groove is a limiting surface, and when the flip cover is rotated to form an acute angle with the main body, the flip cover is close to the side of the main body and away from the end of the plug-in block and abuts against the limiting surface.

[0017] By adopting the above technical solution, when the flip cover is rotated to open the archwire slot, until the flip cover is rotated to the side of the flip cover close to the main body and away from the plug-in block, it abuts against the limit surface. The limit surface limits the rotation angle of the flip cover to an acute angle state, and the opening space of the flip cover is sufficient to put the archwire into or take out the archwire slot; it does not rotate 180 degrees like the flip covers of most brackets in the prior art. When the flip cover needs to be closed, it needs to be rotated at a large angle, which is prone to errors. Therefore, the above structure of the present application can greatly facilitate the operation of the flip cover.

[0018] Preferably, the limiting surface is arc-shaped.

[0019] By adopting the above technical solution, the abutment between the flip cover and the limiting surface is made smoother.

[0020] Preferably, the surfaces of the bracket body and the flip cover that abut against each other are both matched arc surfaces, and the side of the flip cover away from the bracket body is also an arc surface.

[0021] By adopting the above technical solution, the overall roundness of the bracket is increased, thereby improving the comfort between the patient and the oral cavity during the correction process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The flip cover can be locked by simply turning and pressing it, without the need for other parts to lock it. It is easy to operate and thus improves treatment efficiency.

[0024] 2. When the flip cover is rotated to open the archwire slot, the flip cover is rotated until the end of the flip cover, which is closer to the main body and farther from the plug-in block, abuts against the limit surface. The limit surface limits the rotation angle of the flip cover to an acute angle, and the opening space of the flip cover is sufficient to insert or remove the archwire into or out of the archwire slot. Unlike most bracket covers in the prior art, the flip cover does not rotate 180 degrees, which requires a large rotation angle to close the flip cover, which is prone to errors. Therefore, the above-mentioned structure of the present application greatly facilitates the operation of the flip cover.

[0025] 3. Increase the overall roundness of the bracket, thereby improving the comfort between the patient and the oral cavity during the correction process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses a flip-top self-locking bracket. Figure 1 The flip-type self-ligating bracket includes a base plate 1, a bracket body 2 and a flip cover 3. The base plate 1 is fixedly installed on one side of the bracket body 2, and an archwire slot 21 is opened on the other side of the bracket body 2. The cross-sectional area of ​​the base plate 1 is larger than the cross-sectional area of ​​the bracket body 2. The base plate 1 is in an arc shape that matches the tooth surface. The side of the base plate 1 away from the bracket body 2 is used for bonding to the tooth surface. The side of the base plate 1 away from the bracket body 2 is provided with a mesh, so that the base plate 1 is more firmly adhered to the tooth surface.

[0036] Reference Figure 2 、 Figure 3 and Figure 4 The bracket body 2 includes a main body 22, an upper wing 23 and a lower wing 24. The archwire slot 21 is opened on the main body 22. The upper wing 23 and the lower wing 24 are respectively integrally formed and installed on the main body 22 and are located on both sides of the slot of the archwire slot 21; the flip cover 3 is provided on the side of the bracket body 2 where the archwire slot 21 is opened. One end of the flip cover 3 is hinged to the lower wing 24, and the other end is integrally formed with a plug-in block 31 facing the side of the bracket body 2. The upper wing 23 is provided with a plug-in slot 25, and the plug-in block 31 is plugged into the upper wing 23 through the plug-in slot 25; the upper wing 23 is located in the plug-in slot An axis wire 26 is installed in the position 25, and the axis wire 26 extends in the extension direction of the archwire slot 21. A pair of arc-shaped protrusions 32 are integrally formed on the plug-in block 31 at one end away from the flip cover 3 and toward the side away from the archwire slot 21. The arc surface of the arc protrusion 32 faces the side away from the archwire slot 21, and a limiting groove 33 is formed between the arc protrusion 32, the plug-in block 31 and the flip cover 3; when the plug-in block 31 is inserted into the plug-in slot 25, the arc surface of the arc protrusion 32 and the deformability of the axis wire 26 enable the axis wire 26 to be clamped in the limiting groove 33.

[0037] Reference Figure 2The plug-in slot 25 is provided with first mounting holes 231 at both ends of the shaft wire 26 in the length direction. The first mounting holes 231 are connected to the outside of the upper wing 23, and the two ends of the shaft wire 26 are respectively inserted into the first mounting holes 231. When assembling at the beginning, the shaft wire 26 can be inserted through the first mounting holes 231, and then the two ends of the shaft wire 26 are fixed in the first mounting holes 231 by welding, gluing, etc.

[0038] Reference Figure 2 、 Figure 3 and Figure 4 A through slot 27 is provided in the middle position of the side of the insertion slot 25 away from the archwire slot 21, and the through slot 27 extends out of the bracket body 2 in the direction away from the archwire slot 21; a toggle block 34 is integrally formed at one end of the flip cover 3 away from the hinge, and the toggle block 34 is clamped to the bracket body 2 through the through slot 27, and a toggle slot 35 is provided on the side of the toggle block 34 facing the through slot 27, and the groove formed between the toggle slot 35 and the through slot 27 is adapted to the end of the unlocking tool; thus, when the unlocking tool is inserted into the corresponding position of the toggle slot 35, the flip cover 3 can be opened by prying it with a little force.

[0039] The flap 3 is located between the toggle block 34 and the hinge, and is a covering portion 36. The covering portion 36 is as wide as the bracket body 2, so that the archwire can be more stably positioned in the archwire slot 21. The surfaces of the bracket body 2 and the flap 3 that abut against each other are both matching arc surfaces, and the side of the flap 3 away from the bracket body 2 is also an arc surface, so that the comfort of the bracket in the patient's mouth can be improved.

[0040] Refer to 4 and Figure 6 , a pair of lower wings 24 are provided, and the two lower wings 24 are installed on the main body 22 at intervals in the length direction of the archwire slot 21, and a hinge groove 28 is formed between the two lower wings 24. A second mounting hole 241 is opened at the relative position of the two lower wings 24, and the second mounting hole 241 extends in the extension direction of the archwire slot 21. A hinge shaft is installed in the hinge groove 28, and the two ends of the hinge shaft are respectively inserted into the two second mounting holes 241. When assembled at the beginning, the hinge shaft can be inserted through the second mounting holes 241, and then the two ends of the hinge shaft are fixed in the second mounting holes 241 by welding, bonding, etc.; the end of the flip cover 3 away from the plug-in block 31 It is clamped in the hinge groove 28 and allows the hinge shaft to pass through, thereby completing the hinge connection of the flip cover 3; the edge of the end of the main body 22 away from the insertion groove 25 and corresponding to the position of the hinge groove 28 is the limiting surface 221. When the flip cover 3 is rotated to form an acute angle with the main body 22, the side of the flip cover 3 close to the main body 22 and away from the insertion block 31 abuts against the limiting surface 221. The limiting surface 221 is arc-shaped, so that when the flip cover 3 is opened, the flip cover 3 can be rotated to an acute angle through the limiting effect of the limiting surface 221, which not only ensures that the arch wire can be taken out or installed, but also makes it convenient to close the flip cover 3 again later.

[0041] The implementation principle of the flip-type self-locking bracket of the present application is as follows: after the archwire is inserted into the archwire slot 21, the unlocking tool is used to turn the flip cover 3 to rotate until the plug-in block 31 is initially inserted into the plug-in slot 25, and then the front of the flip cover 3 is pressed by the unlocking tool. During the process, the arc surface of the arc-shaped protrusion 32 and the elastic action of the shaft wire 26 make the shaft wire 26 smoothly inserted into the limiting groove 33, thereby completing the locking of the flip cover 3; when the flip cover 3 needs to be opened, the end of the unlocking tool is directly inserted into the through groove 27 and the toggle groove 35, and then slightly pried to move the plug-in block 31 away from the plug-in slot 25 until the end of the flip cover 3 away from the plug-in block 31 abuts against the limiting surface 221, and the archwire can be taken out of or put into the archwire slot 21 through the gap between the flip cover 3 and the bracket body 2.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
