The specific embodiment:
Referring to figs. 1 through Fig. 6, self-locking movable wing bracket, comprises and determines the wing 1 and movable wing 2; Determining the wing 1 disjunctor has bracket seat 11, and offers chute 12, at chute 12 central vertical direction disjunctor limited location cylinders 13; On movable wing 2, disjunctor has pin 21, and pin 21 central authorities are processed with elongated slot 22, and pin 21 both sides are processed with the inclined-plane 23 narrowing, and makes pin 21 narrow compared with chute 12, to abdicate the deformation space of pin 21; The notch place of elongated slot 22 is provided with the first waisting portion 24, middle part is provided with the second waisting portion 25, and waisting portion, when cutting processing, is convexed into by the reserved ripple in pin elongated slot 22 inner sides; The pin 21 of movable wing 2 inserts to be determined in the chute 12 of the wing 1, by the first waisting portion 24, coordinates with spacing cylinder 13, forms primary importance locking mechanism, and the second waisting portion 25 coordinates with spacing cylinder 13, forms second position locking mechanism; First latched position comes off in order to prevent movable wing, and second latched position plays ligation fixation.Determine the wing 1 and movable wing 2 and stretch and have ligature hook 3 respectively towards mating surface outside, to adopt rubber ring ligation arch wire 4.
In addition, at described bracket seat 11, be also provided with a protruding wing 14 determining the side that the wing 1 coordinates with movable wing 2, this protruding wing 14 and determine to have between the wing 1 the fixedly conduit 15 of a constant width, and between the protruding wing 14 and movable wing 2, form the adjustable adjustable conduit 16 of a spacing, for selection of clinical.
Again, movable wing 2 towards with determine a side that the wing 1 coordinates and stretch and have an arch wire to cover 26, when movable wing 2 leans against the protruding wing 14 position, arch wire lid 26 can cover fixedly conduit 15 tops, now the second waisting portion 25 on movable wing 2 pins and spacing cylinder 13 are just in latched position, also be the second latched position, can replace rubber ring ligation location arch wire 4.On the arch wire lid 26 of movable wing, also offer a perforation 27, be convenient to hook movable wing 2 with small tools such as dental explorer, carry out push-and-pull slip movable wing 2, reach the effect of opening and closing, facilitate clinical manipulation.
In this example, spacing cylinder 13 is located on the chute 12 of the protruding wing 14 1 sides, any place that certainly also can establish chute 12 central authorities, but take the chute at the protruding wing 12 places as good, the pin 21 of movable wing 2 can be the shortest like this.
With reference to Fig. 7, when tooth exists vertically to drop, arch wire 4 can be placed in the groove of movable wing 2 arch wire lid 26 formation, by ligature loop ligation, correct.
With reference to Fig. 8, when arch wire 4 can enter the fixedly conduit 15 on bracket seat 11, can promote movable wing 2, utilize the position of second position locking mechanism locking movable wing 2, now the arch wire on movable wing 2 lid 26 is locked in arch wire 4 fixedly in conduit 15 completely, reach and exempt from ligature loop ligation, completely straightening of teeth.Facilitate clinical manipulation, and be conducive to oral hygiene.
With reference to Fig. 9, in figure dotted line be arch wire 4 may in position, or be main arch wire and auxiliary arch wire in position.When movable wing 2 does not also reach the second latched position, 15 mouthfuls of fixedly conduits on bracket seat 11 are open, be conducive to so arch wire 4 that interior outside has dislocation by ligature loop ligation, slowly compel in fixing conduit 15, as the direction of arrow, in movable wing arch wire lid 26, can place auxiliary arch wire simultaneously, assist to correct, until Fig. 8 state.
With reference to Figure 10 to Figure 12, the another kind of structure of this locking mechanism, described chute 12 dual-sides of determining the wing 1 along convexing with circular arc cylinder 17 in groove, and the center of circle line of this circular arc cylinder 17 is perpendicular to pin 21 directions of motion; 21 liang of outsides of pin of movable wing 2, are respectively equipped with symmetrical the first cylindrical portion 28 and the second cylindrical portion 29, the first ends of cylindrical portion 28 in pin 21, the postmedian of the second cylindrical portion 29 in pin 21; The pin 21 of movable wing 2 inserts to be determined, in the chute 12 of the wing, by the first cylindrical portion 28, to coordinate with circular arc cylinder 17, forms primary importance locking mechanism, in this latched position, prevents that movable wing 2 from coming off; The second cylindrical portion 29 coordinates with circular arc cylinder 17, forms second position locking mechanism, and in this latched position, the arch wire lid 26 on movable wing 2 covers above the fixedly conduit 15 of bracket seat 11 just, realizes and exempts from ligature loop ligation.
In this example, circular arc cylinder 17 is located at chute 12 inner sides of the protruding wing 14 1 sides, certainly also can be in the chute inner side of determining the wing 1 one sides, but take the protruding wing 14 1 side Machining Arc cylinders 17 as good.
In above-mentioned all examples, on bracket seat 11, be also provided with an auxiliary tube 18, these auxiliary tube 18 axial lines are parallel with movable wing 2 directions of motion.Auxiliary tube 18 provides positive axis spring to insert location mat positive axis spring elastic force, is determining to form correcting power between the wing 1 and arch wire 4.
