Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in figure 1, the novel active and passive self-ligating bracket comprises a bracket base plate 3 and a bracket parent body 1, wherein an arch wire groove 7 is arranged on the bracket parent body 1, working wings are arranged on two sides of the arch wire groove 7, and a sliding groove 8 is formed in one working wing. As shown in fig. 2, the bottom of the slide groove 8 has an upper step surface 81 and a lower step surface 82, the upper step surface 81 is provided with a spring accommodating hole 83, and two side walls of the lower step surface 82 are respectively provided with two through holes perpendicular to the side wall surfaces, i.e., the first parent pin hole 13 and the second parent pin hole 14. The first and second parent pin holes 13, 14 mate with the locking hook pin holes 42 on the locking hooks 4. As shown in fig. 1, the locking device further comprises a positioning pin 6, and the positioning pin 6 penetrates through the first parent pin hole 13, the second parent pin hole 14 and the locking hook pin hole 42.
As shown in fig. 5 and 6, the locking hook 4 includes a locking hook body 43, a locking dog 41, and a locking hook pin hole 42. The locking hook 4 is provided with a locking hook pin hole 42 at one end and a locking stopper 41 at the other end, and the locking hook pin hole 42 is hinged and fixed with the first parent pin hole 13 and the second parent pin hole 14 on the side wall of the lower step surface 82 in the parent chute 8 through the same positioning pin 6. The entire locking hook 4 is then rotatably connected in the sliding groove 8 of the bracket base 1. The locking stopper 41 is protrudingly provided on the upper surface of the locking hook body 43. The surface of the whole locking block 41 is smooth and circular arc-shaped, so that the sliding lock plate 2 can conveniently slide over the whole locking block 41 when being opened.
As shown in fig. 2, a first mother body chute 11 and a second mother body chute 12 are respectively arranged on two side walls of the chute 8; correspondingly, as shown in fig. 3, the second locking plate slide 22 and the first locking plate slide 23 are provided on both side edges of the sliding locking plate 2. The first lock plate slide 23 is matched with the first parent body slide groove 11, and the second lock plate slide 22 is matched with the second parent body slide groove 12, so that the sliding lock plate 2 can slide along the first parent body slide groove 11 and the second parent body slide groove 12. Further, the inlets of the first mother body chute 11 and the second mother body chute 12 of the mother body are flared openings. The lower bottom surface 111 of the first mother chute 11 and the lower bottom surface 121 of the second mother chute 12 are respectively inclined downwards in a direction away from the arch wire chute, that is, the lower bottom surface 111 of the first mother chute and the lower bottom surface 121 of the second mother chute are inclined slopes. Such a slope facilitates the fitting of the slide lock piece 2. The upper groove surface 112 of the first mother runner 11 and the upper groove surface 122 of the second mother runner 12 may be inclined upward in a direction away from the archwire slot. Namely, the first mother runner upper groove surface 112 and the second mother runner upper groove surface 122 are also inclined surfaces, such inclination is exactly matched with the stress when the sliding lock plate 2 is in the active locking state, that is, such inclined surfaces can further provide the downward locking force to the sliding lock plate, thereby enhancing the self-locking force of the active self-locking. In specific implementation, the inclination angle is adjusted according to the total thickness of the sliding lock piece and the locking hook. In conclusion, the arrangement of the inclination angle facilitates the installation of the sliding lock plate. Meanwhile, the upper surfaces of the first parent body sliding groove 11 and the second parent body sliding groove 12 are respectively arranged in an upward inclined mode towards the direction away from the arch wire groove, and a downward acting force can be further generated when the sliding locking plate is locked.
As shown in fig. 1, since the upper step surface 81 in the slide groove 8 is provided with the spring receiving hole 83, one end of the spring 5 is fixed in the spring receiving hole 83, and the other end thereof is abutted on the lower surface of the locking dog 41 of the locking hook 4. A bar 46 is also provided on the lower surface to retain the spring.
A sliding locking plate 2 is arranged above the locking hook 4 in a matched mode, the sliding locking plate 2 is provided with a sliding end and a locking end, and the upper surface of the locking end is provided with a locking plate arc concave surface 25; the slide-in end has a locking tab notch 24, said locking tab notch 24 cooperating with a locking dog 41 on the locking hook 4. When the sliding lock plate 2 is in the completely closed state, the locking stopper 41 is just clamped at the position of the lock plate notch 24 for limiting.
Further, still be provided with the constant head tank 21 of unblanking on the slide lock piece 2 lower surface, when slide lock piece 2 was in the open mode completely, along with slide lock piece 2's slip, final spacing in constant head tank 21 of unblanking of closure dog 41, slide lock piece 2 realizes opening completely simultaneously.
As shown in fig. 2, a sliding locking piece locking and positioning groove 15 is arranged on the side wall of the arch wire groove 7 on the side of the working wing where the sliding groove 8 is not arranged, and a transverse limiting bump 16 is further arranged in the middle of the sliding locking piece locking and positioning groove 15. Correspondingly, as shown in fig. 4, the locking end of the sliding lock piece 2 is further provided with a transverse locking groove 27 which is matched with the transverse limiting lug 16. As shown in fig. 10, when the slide lock 2 slides into the slide groove 8 to the locking position, the locking piece arc concave surface 25 of the slide lock 2 slides partially or completely into the slide lock locking groove 15 along the notch edge of the locking groove 15. Because the notch border of locking constant head tank 15 interacts with locking plate circular arc concave surface 25, further provide the inward decurrent effort to the locking end of sliding locking plate 2. At the same time, the transverse limit lug 16 snaps into the transverse locking groove 27. The transverse limiting lug 16 is clamped in the transverse locking groove 27, so that the sliding lock plate 2 is further limited transversely.
As shown in fig. 3, the locking end of the slide lock plate 2 is further provided with an unlocking groove 26, and when it is desired to open the slide lock plate 2, a tool is put into the unlocking groove 26 to open the slide lock plate 2.
The bracket assembly process is as follows:
one end of the locking hook 4 with the locking hook pin hole 42 is arranged in the first parent body pin hole 13 and the second parent body pin hole 14 of the parent body, and after the positioning pin 6 is arranged in a penetrating way, the locking hook 4 is hinged with the bracket parent body 1. At this moment, the locking hook 4 can rotate upwards around the positioning pin 6 (at this moment, the locking hook 4 can rotate in a large range), then the spring 5 is installed, the locking hook 4 rotates downwards to press the spring 5, then the sliding lock plate 2 is installed, the rotating range of the locking hook 4 is greatly reduced after the sliding lock plate 2 is installed, and meanwhile, the spring 5 is limited. Under the action of the spring 5, the sliding locking plate 2 can only move up and down in a limited space in the first parent body sliding groove 11 and the second parent body sliding groove 12 of the parent body.
The use method of the bracket comprises the following steps:
as shown in fig. 7, when the teeth are arranged in the front stage, the filament a is penetrated, the filament a is a thinner arch wire, and when the filament a is penetrated and locked, the filament a is not contacted with the slide lock plate 2, as shown in fig. 8. Therefore, the sliding locking plate 2 can not actively generate pressure on the arch wire A, and the bracket can be like a common passive self-locking bracket and can quickly align the dentition.
As shown in fig. 9, in the later root control process, when a thick wire B (i.e. an arch wire with a larger diameter) is threaded, the sliding locking plate 2 is lifted by the arch wire at the moment, as shown in fig. 10, the sliding locking plate 2 generates a reaction force to the arch wire B in turn, so that the active self-locking effect is achieved. Further, as shown in fig. 10, since the slide lock plate 2 generates a reaction force against the archwire B to apply the thick wire B inwardly and downwardly in a direction approaching the lock plate, a clearance angle a is generated between the archwire and the archwire slot. Because the upper surface of sliding lock piece 2 still is provided with locking plate circular arc concave surface 25, locking plate circular arc concave surface 25 and the cooperation of the up end of sliding lock piece locking constant head tank 15, better carry out the locking of the inside downward direction of sliding lock piece 2 to the application of force c of thick silk B. Compared with the existing active self-locking sliding locking plate which can only apply downward active force to the arch wire, an inward force is added, so that the clearance angle a between the thick wire B and the wall of the arch wire groove is greatly reduced. Namely, the self-ligating bracket of the present invention further stabilizes the downward and inward force c due to the engagement of the locking mechanism below the sliding lock plate with the locking detent groove 15 and the locking plate arc concave surface 25, which is an effect that the conventional active self-ligating bracket does not have.
In the use process, if the locking cannot be well realized after long-time use, the situation cannot be caused in normal use. In case of occurrence, the structure of the present invention can restore the locking plate closing force by merely replacing the spring member. The replacement is convenient, and the service life is greatly prolonged.
