Description

Technical fields:

[0001] This utility model relates to the field of orthodontics, specifically to a locking bracket. Background technology:

[0002] Orthodontic appliances, including orthodontic brackets and buccal tubes, are important components of fixed orthodontic techniques. They are appliances used to correct malocclusion of teeth, directly fixed to the surface of the tooth crown. The archwire applies various types of corrective forces to the teeth through the brackets to achieve the orthodontic purpose.

[0003] The applicant filed a utility model application on April 30, 2018, entitled "A Stopping Bracket", with patent number 201820634651.X.

[0004] This patent discloses a stop bracket, including a main body, a cover body mounted on the main body, and a base plate mounted on the bottom surface of the main body. The main body has a transverse archwire groove, and an adjustment plate clearance position is provided on the inner wall of the archwire groove. An adjustment plate is movably mounted on the adjustment plate clearance position, and the adjustment plate is connected to an adjustment mechanism. The other end of the adjustment mechanism is connected to the main body.

[0005] The aforementioned patent uses an adjusting plate to press the archwire in the archwire groove, and the adjusting plate basically covers the mesial and distal directions of the archwire groove. Under the action of the adjusting plate and the sidewall of the archwire groove, the archwire accurately expresses the data that the bracket and archwire should have. However, since the aforementioned patent uses the rotation of the adjusting mechanism to drive the adjusting plate to press the archwire, it is not easy to adjust in the small space of the oral cavity. Utility Model Content:

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a locking bracket that clamps the archwire in a simple and quick way, making it convenient for doctors to operate. In addition, this invention is less likely to touch the patient's mouth, thus reducing the risk of injury to the patient's oral cavity.

[0007] The technical solution of this utility model is: a locking bracket, including a main body and a cover body installed on the main body, and a bottom plate installed on the bottom surface of the main body, wherein a bow wire groove is passed through the main body;

[0008] Among them, a locking mechanism is provided along the length direction of the bow wire groove. The locking mechanism includes a locking plate, a locking limit head, and a locking clamp. The locking limit head is located at both ends of the locking plate along its length direction.

[0009] The locking plate is placed inside the bow wire groove; the locking limit head is engaged at both ends of the main body along the length of the bow wire groove; the locking clamp is used to press the bow wire and is movably connected to the locking limit head.

[0010] In some preferred embodiments, the locking limit head includes a locking limit head body, a locking limit head cover plate, and a locking limit head fixing plate; the locking limit head body is disposed at both ends of the locking plate along its length, one end of the locking limit head cover plate is connected to the locking limit head body, and the other end of the locking limit head cover plate is connected to the locking limit head fixing plate.

[0011] In some further preferred embodiments, the locking limit head fixing plate and the locking clamp are arranged adjacent to each other, and the locking clamp is movably connected to the end of the locking limit head cover plate that is connected to the locking limit head fixing plate.

[0012] In an optional embodiment, the locking clip includes a locking clip body and a locking clip base plate, wherein the locking clip body and the locking clip base plate are perpendicular to each other.

[0013] In a specific implementation, the surface of the locking clamp body facing the locking limit head is the body pressing surface, which is used to press the bow wire. The surface of the locking clamp bottom plate facing the locking limit head cover plate is the bottom plate clamping surface, which is used to prevent the bow wire from moving.

[0014] In a more specific embodiment, the bow wire groove has bow wire groove sidewalls at both ends along its length, and the locking limit head has an inner sidewall in the opposite direction, with the inner sidewall of the locking limit head in close contact with the bow wire groove sidewall.

[0015] In some preferred embodiments, a limiting groove is provided at the adjacent location of the bow wire groove sidewall, and the limiting groove includes a plurality of limiting groove receiving surfaces.

[0016] In some preferred embodiments, the locking and limiting head body has a first mating surface facing the bow wire groove, the locking and limiting head cover plate has a second mating surface facing the bow wire groove, and the body pressing surface is a third mating surface; the first mating surface, the second mating surface, and the third mating surface press the bow wire together.

[0017] In some preferred embodiments, the locking plate is a flat plate structure.

[0018] In some preferred embodiments, the locking limit head and the locking clamp are axially symmetrical along the central axis of the locking plate.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] 1. The locking bracket of this utility model provides a simple and quick way to clamp the archwire, which is convenient for doctors to operate. Compared with the prior art, which requires clamping the archwire by rotation, this utility model only requires the tool to act on the locking clip. After the locking clip deforms, it clamps the archwire, which can fix the archwire. The above operation is simple and quick, which greatly facilitates the operation of doctors and improves the efficiency of correction.

[0021] 2. The locking limiting heads of this invention are located at both ends along the length of the locking plate. The locking clips are used to clamp the archwire and are movably connected to the locking limiting heads. With this design, when the orthodontist uses tools to apply pressure to the locking clips during treatment, the tools will only remain in the mesial-distal direction of the bracket, unlike in existing technologies where the tool easily touches the patient's gums when clamping the archwire by rotation. Therefore, this invention is less likely to touch the patient's oral cavity, reducing the risk of oral injury, and making the locking bracket safer and more reliable.

Detailed Implementation

[0033] The present invention will now be described in detail.

[0034] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] In this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. The terms "vertical," "horizontal," "left," "right," "above," "below," and similar expressions are for illustrative purposes only and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0037] like Figure 1-3 As shown, this embodiment provides a locking bracket, including a main body 1 and a cover 2 mounted on the main body 1, and also includes a bottom plate 3 mounted on the bottom surface of the main body 1, with a bow wire groove 4 penetrating the main body 1;

[0038] The main body 1 is a bracket, and the base plate 3 is used to attach and fix it to the tooth surface to be moved. The main body 1 and the base plate 3 are fixedly connected. The archwire groove 4 is for the archwire 6 to pass through, and the cover body 2 can slide along the main body 1 to open and close the archwire groove 4.

[0039] To address the technical problem that existing methods of tightening the archwire are complex, cumbersome, and inconvenient for doctors to operate, this embodiment, as follows: Figure 1-5 As shown, Figure 5 The arrow in the image indicates the length direction of the bow wire groove 4. A locking mechanism 5 is provided along the length direction of the bow wire groove 4. The locking mechanism 5 includes a locking plate 51, a locking limit head 52, and a locking clamp 53. The locking limit head 52 is located at both ends of the locking plate 51 along its length direction.

[0040] The locking plate 51 is placed in the bow wire groove 4; the locking limit head 52 is clamped at both ends of the main body 1 along the length direction of the bow wire groove 4; the locking clamp 53 is used to press the bow wire and is movably connected to the locking limit head 52.

[0041] In this embodiment, the locking mechanism 5 is arranged along the length of the archwire groove 4. This arrangement is simple and convenient for doctors to operate. Furthermore, the locking plate 51 is also arranged along the length of the archwire groove 4. In this embodiment, the archwire 6 used is a square archwire, but it should be noted that the locking bracket of this invention is also applicable to archwires of other shapes. The locking plate 51 can press one side of the archwire 6; additionally, under the action of the tool, the locking clamp 53 can deform and press another side of the archwire 6, while the locking limiting head 52 can also limit the third side of the archwire 6. Therefore, under the combined action of the three components of the locking mechanism 5 (locking plate 51, locking limit head 52, and locking clamp 53), the archwire 6 is fixed. The locking bracket of this invention has a simple and quick way of pressing the archwire, which is convenient for doctors to operate. This invention only requires the use of a tool to act on the locking clamp 53. After the locking clamp 53 deforms, it presses the archwire to fix it. The above operation is simple and quick, which greatly facilitates the operation of doctors and improves the efficiency of correction.

[0042] On the other hand, the locking limiting head 52 is engaged at both ends of the main body 1 along the length of the archwire groove 4. The connection between the locking limiting head 52 and the main body 1 is simple and direct, making it difficult for the locking mechanism 5 to detach from the main body 1. More specifically, the locking limiting head 52 is located at both ends of the locking plate 51 along its length, and the locking clip 53 is used to press the archwire and is movably connected to the locking limiting head 52. With this arrangement, when the doctor uses a tool to apply force to the locking clip 53 during orthodontic treatment, the tool will only stay in the mesial-distal direction of the bracket, unlike in the prior art where the tool easily touches the patient's gums when pressing the archwire by rotation. Therefore, this invention is less likely to touch the patient's oral cavity, and the patient's oral cavity is less likely to be damaged, making the locking bracket safer and more reliable.

[0043] More preferably, the locking head 52 includes a locking head body 521, a locking head cover plate 522, and a locking head fixing plate 523. The locking head body 521 is located at both ends along the length of the locking plate 51. One end of the locking head cover plate 522 is connected to the locking head body 521, and the other end is connected to the locking head fixing plate 523. In this embodiment, the locking head body 521, the locking head cover plate 522, and the locking head fixing plate 523 form a structure similar to "]", surrounding the bowwire 6 and positioning the bowwire 6 within the aforementioned "]" structure of the locking head 52. Furthermore, it should be noted that the locking head body 521, the locking head cover plate 522, and the locking head fixing plate 523 are all solid structures and are not easily deformed.

[0044] More specifically, the locking stop head fixing plate 523 and the locking clip 53 are arranged adjacent to each other, and the locking clip 53 is movably connected to the end of the locking stop head cover plate 522 that connects to the locking stop head fixing plate 523. In this embodiment, as... Figure 2-4 As shown, the locking limit head fixing plate 523 and the locking clamp 53 are adjacent to each other and both extend in the same direction. The locking limit head fixing plate 523 is a solid structure and is not easily deformed; however, the locking clamp 53 can deform under the action of a tool to press against the bowwire, thus fixing the bowwire. Figure 7 Until the locking clip 53 is not tightened, the bow wire 6 is not in a tightened state, such as Figure 8 This refers to the state in which the locking clip 53, after being deformed by the tool, presses against the bow wire 6.

[0045] Preferably, the locking clip 53 includes a locking clip body 531 and a locking clip base plate 532, with the locking clip body 531 and the locking clip base plate 532 perpendicular to each other. In this embodiment, the locking clip body 531 can directly contact the bowwire 6, and the locking clip body 531 presses the bowwire 6, such as... Figure 8 In the position, the locking clip body 531 and the locking clip base plate 532 are perpendicular to each other. The locking clip base plate 532 plays a role in limiting the archwire 6, preventing the archwire 6 from shifting in the positioning state and affecting the orthodontic effect.

[0046] More preferred, such as Figure 2-3As shown in Figures 7-8, the surface of the locking clamp body 531 facing the locking limit head 52 is the body pressing surface 531a, which is used to press the bowwire. The surface of the locking clamp base plate 532 facing the locking limit head cover plate 522 is the base plate clamping surface 532b, which is used to prevent the bowwire from moving. In this embodiment, the body pressing surface 531a faces the bowwire 6, and the body pressing surface 531a can directly contact the bowwire 6 to produce a pressing effect. The base plate clamping surface 532b also faces the bowwire 6. As described above, this base plate clamping surface 532b is set to limit the bowwire 6, preventing the bowwire 6 from shifting in the positioning state and affecting the orthodontic effect.

[0047] Further preferred, such as Figure 4-6 As shown, Figure 5 The middle arrow indicates the length direction of the bow wire groove 4. Bow wire groove sidewalls 41 are provided at both ends along the length direction of the bow wire groove 4. An inner sidewall 524 of the locking and limiting head 52 is provided on the opposite side of the locking and limiting head 52, and the inner sidewall 524 of the locking and limiting head is in close contact with the bow wire groove sidewall 41. A limiting groove 101 is provided adjacent to the bow wire groove sidewall 41, and the limiting groove 101 includes several limiting groove receiving surfaces 101a.

[0048] In this embodiment, to enable the locking limit head 52 to be engaged at both ends of the main body 1 along the length of the bow wire groove 4, a stepped structure is provided at both ends of the main body 1 along the length of the bow wire groove 4. This stepped structure includes a limiting groove receiving surface 101a and a bow wire groove sidewall 41. The limiting groove receiving surface 101a serves to support and position the locking limit head 52. Figure 1 , 3 As shown in Figures 4 and 5, the locking limit head fixing plate 523 rests against the limiting groove receiving surface 101a, and the limiting groove receiving surface 101a can support the locking limit head fixing plate 523, and as shown in Figures 4 and 5, the locking limit head fixing plate 523 rests against the limiting groove receiving surface 101a, and the locking limit head fixing plate 523 rests against the limiting groove receiving surface 101a. Figure 5 In the middle, the limiting groove receiving surface 101a is located in at least three directions, so that the locking limiting head 52 can be positioned so that the locking limiting head 52 can be locked at both ends of the main body 1 along the length direction of the bow wire groove 4.

[0049] like Figure 4-6 As shown, on the other hand, the inner wall 524 of the locking limit head is in close contact with the side wall 41 of the archwire groove. This arrangement reduces the gap between the locking mechanism 5 and the main body 1, lowering the probability of food residue remaining inside the main body 1. Since this locking bracket is used in the human oral cavity for a long time, food residue will be generated during eating. Furthermore, the locking mechanism 5 is tightly fitted to the main body 1; therefore, the gap between the locking mechanism 5 and the main body 1 must be as small as possible.

[0050] Further preferred, such as Figure 7-8As shown, the locking head body 521 has a first mating surface 71 facing the bow wire groove 4, the locking head cover plate 522 has a second mating surface 72 facing the bow wire groove 4, and the body pressing surface 531a is a third mating surface 73; the first mating surface 71, the second mating surface 72, and the third mating surface 73 press the bow wire 6 together. Figure 8 In the middle, the upper side of the bow wire 6 is in contact with the first mating surface 71, the right side of the bow wire 6 is in contact with the second mating surface 72, and one end of the lower side of the bow wire 6 is in contact with the third mating surface 73. Thus, the locking mechanism 5 presses the bow wire 6 in three directions. Through the action of the locking mechanism 5, the bow wire 6 is not easy to loosen or displace, and the fixing and correction effect is good.

[0051] More preferably, the locking plate 51 is a flat plate structure. In this embodiment, the locking plate 51 extends along the length direction of the bow wire groove 4. The flat plate structure of the locking plate 51 can better fit with the bow wire 6, thereby better pressing the bow wire 6 and achieving a good fixing effect for the bow wire 6.

[0052] Specifically, the locking limit head 52 and the locking clamp 53 are axially symmetrical along the central axis of the locking plate 51. In this embodiment, the locking limit head 52 and the locking clamp 53 are axially symmetrical along the central axis of the locking plate 51, which makes the overall integrity of the locking mechanism 5 better. The locking limit head 52 is engaged at both ends of the main body 1 along the length direction of the bow wire groove 4.

[0053] The working principle of this utility model is as follows:

[0054] 1. First, move the cover part 2 to the open state, exposing the bow wire groove 4, and put the bow wire 6 into the bow wire groove 4.

[0055] 2. With the cover 2 in the open position, the opening of the locking mechanism 5 faces the wire groove 4. Then, the locking mechanism 5 is inserted into the wire groove 4, forming a... Figure 1 In state 7, the locking limit head 52 is engaged at both ends of the main body 1 along the length of the bow wire groove 4; the locking limit head body 521, the locking limit head cover plate 522, and the locking limit head fixing plate 523 form a structure similar to "]", which surrounds the bow wire 6 and positions the bow wire 6 within the structure of the locking limit head 52.

[0056] 3. Finally, use a tool to deform the locking clip 53, forming... Figure 8 In this state, the locking clamp 53 can deform and press against another side of the bow wire 6, while the locking limit head 52 can also limit the third side of the bow wire 6. Therefore, under the combined action of the three components of the locking mechanism 5 (locking plate 51, locking limit head 52, and locking clamp 53), the bow wire 6 is fixed.

[0057] The above are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any substitutions and improvements made without departing from the concept of this utility model shall fall within the scope of protection of this utility model.
