Detailed Description
The following are specific embodiments of the invention and the technical solutions of the invention will be further described with reference to the accompanying drawings, but the invention is not limited to these embodiments.
As shown in figure 1, the novel active and passive self-locking bracket comprises a bracket bottom plate 3 and a bracket parent body 1, wherein an arch wire groove 7 is formed in 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 chute 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 through holes perpendicular to the side wall surfaces, namely, the first parent pin hole 13 and the second parent pin hole 14, are respectively formed in two side walls of the lower step surface 82. The first and second parent pin holes 13 and 14 are engaged with the locking hook pin holes 42 on the locking hooks 4. As shown in fig. 1, the locking pin 6 is further included, and the locking 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 stopper 41, and a locking hook pin hole 42. The locking hook 4 has a locking hook pin hole 42 at one end and a locking stop 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 thus rotatably connected in the slot 8 of the bracket body 1. The locking stopper 41 is convexly provided on the upper surface of the locking hook body 43. The surface of the whole locking stop 41 is in a smooth arc shape, so that the sliding lock plate 2 can conveniently slide across the whole locking stop 41 when being opened.
As shown in fig. 2, a first parent sliding groove 11 and a second parent sliding groove 12 are respectively arranged on two side walls of the sliding groove 8; correspondingly, as shown in fig. 3, the two sides of the sliding lock piece 2 are provided with a second lock piece sliding bar 22 and a first lock piece sliding bar 23. The first locking piece slide 23 is engaged with the first parent chute 11, and the second locking piece slide 22 is engaged with the second parent chute 12, so that the sliding locking piece 2 can slide along the first parent chute 11 and the second parent chute 12. The inlets of the first parent body chute 11 and the second parent body chute 12 of the further parent bodies are provided with horn-shaped openings. The lower bottom surface 111 of the first parent sliding groove 11 and the lower bottom surface 121 of the second parent sliding groove 12 are respectively inclined downwards in a direction away from the archwire groove, i.e. the lower bottom surfaces 111 and 121 of the first parent sliding groove are inclined planes. Such a bevel facilitates the loading of the slide lock tab 2. And the upper slot surface 112 of the first parent slot 11 and the upper slot surface 122 of the second parent slot 12 may also be simultaneously disposed to be upwardly inclined in a direction away from the archwire slot, respectively. That is, the first upper groove surface 112 of the first parent sliding groove and the second upper groove surface 122 of the second parent sliding groove are inclined planes, and the inclination is just matched with the stress of the sliding lock plate 2 in the active locking state, that is, the inclined planes can further provide the downward locking force for the sliding lock plate, so that the self-locking force of active self-locking is enhanced. In particular, the tilt angle is adjusted according to the total thickness of the slide lock tab and the locking hook. In summary, the arrangement of the inclination angle facilitates the loading of the sliding lock piece. At the same time, the upper surfaces of the first parent sliding groove 11 and the second parent sliding groove 12 are respectively arranged in an upward inclined way in the direction away from the archwire groove, and a downward acting force is further generated when the sliding lock plate is locked.
As shown in fig. 1, since the spring receiving hole 83 is provided on the upper stepped surface 81 in the chute 8, one end of the spring 5 is fixed in the spring receiving hole 83, and the other end is abutted against the lower surface of the lock stopper 41 of the lock hook 4. A stop strip 46 is also provided on the lower surface for blocking the spring.
A sliding lock plate 2 is arranged above the further locking hook 4 in a matched manner, the sliding lock plate 2 is provided with a sliding-in end and a locking end, and the upper surface of the locking end is provided with a lock plate arc concave surface 25; the slide-in end has a locking tab notch 24, said locking tab notch 24 cooperating with a locking stop 41 on the locking hook 4. When the sliding lock piece 2 is in the completely closed state, the locking stop 41 is just clamped at the position of the lock piece notch 24, and limiting is performed.
Further, an unlocking positioning groove 21 is further formed in the lower surface of the sliding lock piece 2, when the sliding lock piece 2 is in a fully opened state, the locking stop 41 is finally limited in the unlocking positioning groove 21 along with the sliding of the sliding lock piece 2, and meanwhile the sliding lock piece 2 is fully opened.
As shown in fig. 2, a sliding lock plate locking and positioning groove 15 is arranged on the side wall of the archwire slot 7 on the side of the working wing where the sliding groove 8 is not arranged, and a transverse limit bump 16 is further arranged in the middle of the sliding lock plate 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 limit bump 16. As shown in fig. 10, when the slide lock piece 2 slides into the slide groove 8 to the lock position, the lock piece circular arc concave surface 25 of the slide lock piece 2 partially or completely slides into the slide lock piece lock positioning groove 15 along the notch edge of the lock positioning groove 15. The inward downward force on the locking end of the slide lock tab 2 is further provided by the interaction of the notch edge of the locking detent 15 with the arcuate concave surface 25 of the lock tab. At the same time, the lateral limit projections 16 snap into the lateral locking grooves 27. The lateral limit projection 16 is clamped into the lateral locking groove 27, so that the sliding lock plate 2 is further laterally limited.
As shown in fig. 3, the locking end of the slide lock piece 2 is further provided with an unlocking groove 26, and when the slide lock piece 2 needs to be opened, the slide lock piece 2 is opened using a tool placed in the unlocking groove 26.
The assembly process of the bracket is as follows:
the end of the locking hook 4 with the locking hook pin hole 42 is arranged in the first parent pin hole 13 and the second parent pin hole 14 of the parent body, and after the positioning pin 6 is penetrated, the locking hook 4 is hinged with the bracket parent body 1. At this time, the locking hook 4 can rotate upward around the positioning pin 6 (at this time, the locking hook 4 can rotate in a large range), then the spring 5 is installed, then the locking hook 4 is rotated downward to press the spring 5, then the sliding lock piece 2 is installed, the rotation range of the locking hook 4 is greatly reduced after the sliding lock piece 2 is installed, and meanwhile the spring 5 is limited. Under the action of the spring 5, the slide lock piece 2 can only move up and down to a certain extent in the limited space in the first and second parent sliding grooves 11 and 12.
The use method of the bracket is as follows:
as shown in fig. 7, during the early tooth discharge, filament a, i.e., the finer archwire, is threaded and, when filament a is threaded and locked, filament a is not in contact with slide lock tab 2, as shown in fig. 8. The sliding lock piece 2 will not actively exert pressure on the archwire a, and the brackets can be aligned quickly like a typical passive self-locking bracket.
In the process of later root control, as shown in fig. 9, when the thick wire B (i.e. the arch wire with a larger diameter) is penetrated, the sliding lock plate 2 is lifted by the arch wire, and as shown in fig. 10, the sliding lock plate 2 in turn generates a reaction force on the arch wire B, so that an active self-locking effect is achieved. Further, as shown in fig. 10, a clearance angle a is created between the archwire and the archwire slot because the sliding lock plate 2 reacts to the archwire B to force the thick wire B inwardly and downwardly toward the direction of the locking plate. Because the upper surface of the sliding lock plate 2 is also provided with the lock plate arc concave surface 25, the lock plate arc concave surface 25 is matched with the upper end surface of the sliding lock plate locking positioning groove 15, and the force c of the sliding lock plate 2 to the thick wire B is better locked in the inward and downward directions. Compared with the existing active self-locking sliding lock plate, the active self-locking sliding lock plate can only apply downward active force to the archwire, so that inward force is increased, and the clearance angle a between the thick wire B and the wall of the archwire is greatly reduced. Namely, the self-locking bracket of the invention further stabilizes the downward inward force c due to the fact that the locking mechanism below the sliding lock plate gives downward and inward force to the sliding lock plate, and meanwhile, the upper end of the locking positioning groove 15 of the sliding lock plate is matched with the arc concave surface 25 of the locking plate, so that the self-locking bracket has no effect in the existing active self-locking bracket.
In the use process, if the lock cannot be well locked after long-time use, the normal use is of course not performed. In the event of this, the structure of the present invention can restore the locking plate closing force by simply replacing the spring member. The replacement is convenient, and the service life is greatly prolonged.

As shown in fig. 14, the locking hook 4 is hinged by the first locking hook positioning shaft 44 and the second locking hook positioning shaft 45 being respectively clamped into the first parent clamping groove 17 and the second parent clamping groove 18, so that the locking hook 4 and the bracket parent 1 are assembled.
Example 3
Other structures of this embodiment are the same as those of embodiment 1, except that: the arrangement modes of the elastic supporting member springs are different, specifically, as shown in fig. 15, the spring accommodating holes are formed as concave accommodating holes 84 shown in fig. 15, meanwhile, guide rods 85 are arranged in the concave accommodating holes 84, and the springs are sleeved on the guide rods 85, so that stability is improved. Correspondingly, as shown in fig. 17, the lower surface of the locking hook 4 where the other end of the spring is located may also be provided with a spring positioning hole 46 to further fix the spring. As shown in fig. 18, the lower surface of the locking hook 4 at the other end of the spring may be provided with a spring positioning protrusion 47, and the protrusion 47 may be in a convex rounded point shape, or may be in other shapes, so long as the shape for positioning the spring is convenient, and the shape is not limited to the rounded point shape.
