Archwire slot 11 is provided on base 1 made of metal material, so as to avoid ceramic material in related art scheme Base 1 be easy under the action of arch wire the damaged and larger problem of frictional force, convenient for the adjustment of arch wire.Cover board is in tooth white material In the selection of material, in one embodiment, cover board is the ceramic material of tooth white.

Ceramic material is generally understood as being sintered by inorganic material, can also be by organic in some concrete conditions Materials reinforcing.Tooth white does not specify the color of a certain specific rgb value (or other color parameters), and refers to and patient teeth Close white.In the specific implementation process, it can be finely adjusted according to the different color of patient, core purpose is to reduce The color difference with tooth of bracket improves aesthetic measure.

The central role of bracket is fixed arch wire, allows arch wire that can generate stress to bracket, bracket by stress transfer extremely On tooth, to realize adjustment of the tooth relative to gum on spatial position.Therefore bracket needs to realize the limit to arch wire. In one embodiment, cover board includes the first cover board 301 being fixedly mounted with base 1 and the second lid being slidably matched with base 1 Plate 302, the second cover board 302, which has, blocks the position of 11 notch of archwire slot with the mutual split of the first cover board 301, and with the One cover board 301 is separated from each other to avoid the open state of 11 notch of archwire slot.

When the second cover board 302 is in position, archwire slot 11 is closed, and arch wire is constrained in archwire slot 11.According to The different shape of patient teeth adjusts Bracket placement, and the stress of torsion can be generated to arch wire, and arch wire is because natural resiliency can be to support Slot applies reaction force, and the power of arch wire is transferred on the tooth of patient by bracket, so as to adjust the position of tooth spatially and State.In order to facilitate the installation and adjustment of arch wire, the second cover board 302 also has open state, and arch wire can be freely detached from this time Archwire slot 11 facilitates the operation in different therapeutic process.

The opposite sliding of first cover board 301 and the second cover board 302 can improve the positioning of the two while facilitating operation Precision improves the correction accuracy to tooth, provides finer rectification effect.In specific setting, the first cover board 301 can be with The notch of enclosure portion archwire slot 11 can also avoid the notch of archwire slot 11 completely, and the two cuts both ways.First cover board, 301 envelope Closing part divides the notch of archwire slot 11 that can reduce the possibility that arch wire surprisingly deviates from archwire slot 11, but also allows and adjust arch wire more not Just, it is easy to be influenced by the first cover board 301；The notch of the first evacuation archwire slot 11 completely of cover board 301 can be convenient arch wire Adjustment, but when arch wire stress active force may be generated to the second cover board 302, cause closing to be failed, arch wire deviates from archwire slot 11, it brings inconvenience to the life of patient.Therefore it needs according to different patient profiles, the on-demand adjusted design form such as wish.

In correcting process, arch wire and bracket all can be by biggish stress, therefore the first cover board 301 and the second cover board 302 also need to guarantee bonding strength while activity, and in one embodiment, base 1 is in the side backwards to net bottom 2 with difference It is in the first support portion 14 and the second support portion 15 of 11 notch two sides of archwire slot, the fixation of the first cover board 301 is located at first On support part 14, the second cover board 302 is slidably mounted on the second support portion 15.

In the embodiments illustrated in the figures, the first support portion 14 and the second support portion 15 are structure as a whole with base 1, and point For cloth in 11 two sides of archwire slot, the second cover board 302 can be with respect to the opposite sliding of the second support portion 15, thus closing or open archwire slot 11.First support portion 14 and the second support portion 15 divide in addition to for other than fixing the first cover board 301 and the second cover board 302, moreover it is possible to use The component of the adjuvant treatments such as the elastic component 4 in the device of some extensions of fixation, such as between bracket and bracket.

Second cover board 302 by the guidance of the second support portion 15 far from or close to the first cover board 301, in order to improve the first lid The cooperation precision of plate 301 and the second cover board 302, in one embodiment, in the first cover board 301 the one of the second cover board 302 of direction Side has limited step 3011；Second cover board 302 of position, which is taken to set, to be fixed on limited step 3011.

The not necessarily stairstepping in actual design of limited step 3011 may be the curved surface of a consecutive variations, be used for Realize being mutually aligned and positioning for the first cover board 301 and the second cover board 302.Pass through the guidance and limit of limited step 3011, energy Enough realize the precise positioning of the first cover board 301 and the second cover board 302, common cooperation is to improve the first cover board 301 and the second cover board The sealing effect of 302 pairs of archwire slots 11.

In one embodiment, limited step 3011 is in the side of 11 notch of archwire slot, the second cover board 302 of position It crosses 11 notch of archwire slot and takes to set and be fixed on limited step 3011.

Second cover board 302 needs to lean out the second support portion 15 1 in the actual implementation process, in order to close archwire slot 11 Point, limited step 3011 can be provided and be supported and fixed for the part that leans out of the second cover board 302.According to the knot of limited step 3011 Structure is different, is capable of providing the position-limiting action of different directions and dimension, limited step 3011 can be according to different service condition tune It is whole.

Other than limited step 3011, the installation of the second cover board 302 mainly passes through the support of the second support portion 15, therefore one In embodiment, the second support portion 15 is equipped with two sliding rails 151 being arranged side by side, and the two opposite sides of the second cover board 302 are embraced in opposite directions Hold together on two sliding rails 151, the second cover board 302 is moved along two sliding rails 151 to be switched between position and open state.

Two sliding rails 151 can provide stable installation effect for the second cover board 302, apply in arch wire stress to bracket and make When firmly, the second cover board 302 can be transmitted active force by sliding rail 151, and process is rescued in realization.

During rescuing, arch wire needs stress, and the second cover board 302 may be driven to generate displacement；The behaviour such as doctor simultaneously The second cover board 302 will also be operated during adjusting arch wire by making personnel, therefore in one embodiment, the second support portion 15 with It is additionally provided with limitation 302 motion amplitude of the second cover board between second cover board 302, prevents the second cover board 302 from falling off in the limit of base 1 Part.

The effect of locating part can effectively avoid falling off for the second cover board 302 from failing with installation, improve the stability of bracket. In some embodiments, locating part can also provide the effect of locking for the position and open state of the second cover board 302.

In actual installation process, the first cover board 301 can by bonding, welding, the modes such as fastener with first Support part 14, which is realized, to be fixedly mounted.In one embodiment, in the short transverse of base 1, at least part of the first support portion 14 Width gradually broaden with prevent the first cover board 301 deviate from the first support portion 14.

In the present embodiment, it is gradually broadened by at least part of width of the first support portion 14 to realize the first cover board 301 and the first cooperation between support portion 14.At least part of width of first support portion 14, which gradually broadens, to be embodied Also there are many forms in the process.Such as locate the form of dovetail groove out as shown in the figure, the first cover board 301 and the first support portion 14 are inserted After connecing cooperation, the first cover board 301 can only be slided with respect to the first support portion 14, then by bonding, be welded, and the modes such as fastener limit The installation of the first cover board 301 had both may be implemented in sliding between first cover board 301 and the first support portion 14.The advantages of design, exists In easy for installation, effect is good, and the first cover board 301 is not easy, and can bear biggish stress.Dovetail groove shown in crossing in figure is main For preventing the first support portion of prolapse upwards 14 in 301 figure of the first cover board, in some embodiments, dovetail groove may there are many become Change, to prevent the first cover board 301 relative to the movement in 14 all directions of the first support portion.

In the related art, cover board is used to close archwire slot 11, therefore not with the positional relationship in the short transverse of base 1 It is important, it can be arranged on demand, but in the application, cover board is also used to cover base 1 and net bottom 2 other than closing archwire slot 11, Therefore in one embodiment, along 1 short transverse of base, the projected area of base 1 at least 90% be in cover board view field It is interior.

The short transverse of base 1 refers to the direction for being approximately perpendicular to the dental surface of patient, that is, when facing patient, observer It should not find 1 part of base, be mainly observed the deck portion of tooth white, to realize stealthy function, be provided for patient good Good perception.

Referring to figs. 1 to 5, the technical solution of the application also discloses design form of the bracket on self-locking structure.Bracket packet The base 1, the net bottom 2 for being fixed on 1 side of base, the cover board for being mounted on 1 other side of base for having archwire slot 11 are included,

The bottom surface of cover board and the top surface of base 1 mutually recline and are slidably matched；

The top surface of base 1 is equipped with the elastic component 4 of bar shaped, there are two the bottom surface of cover board is sequentially arranged along cover board glide direction Card slot, for towards the transition ridge 31 of 1 direction of base protrusion between two card slots；

A part of elastic component 4 is active section 41, and when cover board slides, active section 41 enters corresponding one via transition ridge 31 In card slot, it is additionally provided with escape groove 12 in the top surface of base 1, to accommodate deformations of the active section 41 when offseting with transition ridge 31 Position.

Bracket is by cover closure archwire slot 11, to realize the sky to tooth in the stress transfer to tooth of arch wire Between position adjustment.In installation, adjustment arch wire, need to open the open archwire slot 11 of cover board to facilitate operation；In non-installation, tune When whole arch wire, for cover closure to guarantee that arch wire is housed in archwire slot 11, arch wire applies active force to bracket.Therefore cover board needs Meet it is easy to install, it is self-positioning, be not easy the work characteristics of accidental movement.By the cooperation of elastic component 4 and transition ridge 31, realize to lid The positioning of multiple positions of plate.Transition ridge 31 is from cover board to 1 direction of base protrusion, and when cover board is mobile, transition ridge 31 is moved with cover board It is dynamic, it can be interfered with elastic component 4, therefore the movement of cover board needs to squeeze elastic component 4 by transition ridge 31 and drives elastic component 4 Deformation forms energy ladder.When the external world is less than the energy ladder to cover board acting, cover board is unable to completion status variation, guarantees The stability of cover board state, to ensure that the stabilization of bracket state.

Referring to figs. 1 to 8, during the movement of cover board, transition ridge 31 is high in base 1 in addition to that can generate to elastic component 4 It spends outside the first active force on direction, can also generate the second active force on cover board moving direction, the second active force can make Elastic component 4 generates the movement tendency moved together with cover board, if not containing the movement tendency, it is mobile that it will cause elastic components 4, Then the location status of cover board not can determine that, can not play the technical effect of cover board positioning.In specific implementation, the peace of elastic component 4 Dress mode have it is multiple, such as by the bonding of elastic component 4, welding, be fixed on base 1 by modes such as fasteners, in an embodiment In, the top surface of base 1 is equipped with mounting groove 13, and elastic component 4 is placed in the mounting groove 13, and escape groove 12 is under mounting groove 13 It is connected just and with mounting groove 13.

For other embodiments, the mode of mounting groove 13 is relatively simple, and structure is simple, easy for installation.For The material of base 1 and elastic component 4, property tolerance are high.Mounting groove 13 is for containing the movement that elastic component 4 is moved with cover board Trend, therefore active force is mainly applied to elastic component 4 by the two sides cell wall in the cover board direction of motion.Implementation as shown in the figure In mode, it is two sections that mounting groove 13, which is divided to, and the both ends of elastic component 4 are housed in respectively in respective mounting groove 13,13 axis of mounting groove It is parallel and conllinear.In certain specific embodiments, the axial direction of mounting groove 13 is not necessarily parallel, also not necessarily conllinear.

The precision of mounting groove 13 is mainly reflected on the two sidewalls in the cover board direction of motion, other directions can be set on demand It sets, in one embodiment, mounting groove 13 penetrates through the top surface of base 1 on the extending direction of itself.

The design of perforation facilitates production and processing.In certain embodiments, such as some pairs of 4 positioning accuracies of elastic component are higher In the case where, mounting groove 13 can not also penetrate through.

In one embodiment, the extending direction of mounting groove 13 and elastic component 4 is vertical with cover board glide direction.

The vertical design of mounting groove 13 can be to avoid mounting groove 13 and the angle of cover board glide direction by 31 pairs of bullets of transition ridge Property part 4 Force decomposition be the axial component of elastic component 4, which may cause elastic component 4 in the axial direction side of mounting groove 13 It moves up, declines the case where even positioning failure so as to cause positioning accuracy.

The working condition of elastic component 4 passes through mounting groove 13 and the adjustment of escape groove 12 and limitation, in one embodiment, escape groove 12 be blind slot；Or escape groove 12 is through slot.The design of blind slot avoids the excessive deformation of elastic component 4 that abrasion or itself installation is caused to lose Effect.The design form of through slot can be improved the deformation quantity of elastic component 4, improve the locking effect of cover board.Specifically how to be arranged can be with Selection on demand.

The installation effect of elastic component 4 is also related with the matching relationship of mounting groove 13, and in one embodiment, active section 41 is located at The middle part of 4 length direction of elastic component, and position is corresponding with transition ridge 31；The both ends of elastic component 4 are positioning section 42, each positioning section 42 extend respectively across transition ridge 31, cover board when sliding each positioning section 42 be limited in mounting groove 13.

In some special circumstances, by the way that the matching relationship of mounting groove 13 and elastic component 4 is arranged, it may be mentioned for elastic component 4 For additional advantageous effects.Such as by shifting to install mounting groove 13, preloaded to be provided for elastic component 4, so as to adjust The size of the trigger force of elastic component 4 changes driving force size of cover board etc..

Cover board is related with the specifically design of elastic component 4, mounting groove 13 and escape groove 12 in the moment variations of sliding process, In one embodiment, on 4 length direction of elastic component, escape groove 12 is narrower than mounting groove 13, and uses inclined-plane mistake at boundary position It crosses；When active section 41 is by transition 31 compressional deformation of ridge, escape groove 12 is sunk to via inclined-plane.

The mutual abrasion between elastic component 4, mounting groove 13 and escape groove 12 can be reduced by inclined-plane, extends bracket Service life.Also the interaction of transition ridge 31 and elastic component 4 can be allowed more smoothly.Simultaneously in one embodiment, transition ridge 31 wherein side is the first inclined-plane 311 that cover board moves ahead when closing archwire slot 11 and elastic component 4 offsets, and the other side is after cover board The second inclined-plane 312 to offset when removing open archwire slot 11 with elastic component 4；

The gradient of the gradient on the first inclined-plane 311 less than the second inclined-plane 312.

The design on the first inclined-plane 311 and the second inclined-plane 312 can provide more linear driving force for the movement of cover board and need It asks.The operators such as doctor are facilitated to operate.The gradient on the first inclined-plane 311 is less than the second inclined-plane 312, i.e. the second inclined-plane 312 The gradient is bigger, and pace of change is faster.Second inclined-plane 312 offsets when dropping back for cover board and open archwire slot 11 with elastic component 4, therefore slope Degree is bigger, is more unfavorable for cover board recession, thus the possibility for preventing cover board from surprisingly opening.

Outside the switching for providing state except through transition ridge 31, the limit of sports record formation of cover board is also required to limit.It is real one It applies in example, the bottom surface of cover board is equipped with first and platform 32 and second is stopped to stop platform 33, and along cover board glide direction, two blocking platforms are located respectively In the two sides of transition ridge 31；

Wherein the first blocking platform 32 closes on 11 side of archwire slot, and second stops platform 33 far from 11 side of archwire slot, two cards Slot includes:

First card slot 34 is between the first blocking platform 32 and transition ridge 31, and cover board is when closing archwire slot 11, elastic component 4 active section 41 is in the first card slot 34；

Second card slot 35 is between the second blocking platform 33 and transition ridge 31, and cover board is when archwire slot 11 is closed in opening, elasticity The active section 41 of part 4 is in the second card slot 35.

First card slot 34 is practical to be made of the first blocking platform 32 and the second inclined-plane 312, and the second card slot 35 is practical by the second resistance The movement that block machine 33 and the first inclined-plane 311 composition, the first blocking platform 32 and the second blocking platform 33 are used to limit cover board is formed, with mistake 4 deformation of driving elastic component of ridge 31 is crossed to avoid the form of transition ridge 31 difference, first stops platform 32 and second to stop platform 33 It directly offsets with elastic component 4, prevents cover board from continuing to move by elastic component 4, therefore, first stops platform 32 and second to stop platform 33 Should have and almost vertically offset with the blocking surface of the cover board direction of motion and elastic component 4.

When blocking surface and elastic component 4 offset, cover board cannot continue to move.In one embodiment, in 4 length side of elastic component Upwards, first stops platform 32, second to stop platform 33 and transition ridge 31 wide, and position is corresponding with the active section 41 of elastic component 4.

It is wherein wide to be not limited to numerically absolute equal, but it is equal on approximate range.Such as gap does not surpass Cross 25%.The design is advantageous in that the blocking effect that can increase the first blocking platform 32 and the second blocking platform 33 and transition The locating effect of ridge 31.

The specifically used process of bracket is illustrated below with reference to specific component:

Referring to figs. 1 to 11, when producers assemble bracket, elastic component 4 is put into mounting groove 13 first, is then passed through Cover board is packed by the sliding rail of the left and right sides of base 1, cover board can only on base 1 Bidirectional slide, when cover board is close to archwire slot 11, Just driving 4 deformation of elastic component of cambered surface 331 at the top (i.e. second stops the top of platform 33) of the cover board direction of motion, 4 work of elastic component Make 41 deformation of section and enter evacuation area, passes through 13 position of mounting groove, the entrance of elastic component 4 to avoid the top of the cover board direction of motion The active section 41 of second card slot 35, elastic component 4 resets, at this time because active section 41 can be driven to avoid cover board without structure, because This cover board can not extracted out normally, and production and assembly are completed.

When the operators such as doctor need using bracket, bracket is fixed on by dental surface by net bottom 2 first, then Arch wire is put into archwire slot 11, cover closure archwire slot 11 is driven, under the driving of the second inclined-plane 312 of transition ridge 31, elasticity 41 shape of active section of part 4 enters escape groove 12, and when cover board completely encloses archwire slot 11, elastic component 4 is directed at the first card slot 34, bullet Property part 4 active section 41 reset, to lock cap locations.

When the operators such as doctor need to open bracket adjustment arch wire, reverse operating cover board is not repeating again.
