Description
Technical field
The utility model relates to medical instruments, and in particular to a kind of bead-moving type locking bracket.
Background technique
Bracket is the important component of fixed orthodontics, is directly adhered to crown surfaces with bonding agent, bracket is not generally by
Rust steel, bioceramic or compound resin are made, and main function is fixed arch wire, so that arch wire is made preferably to play a role,
Orthodontic force is transmitted, the movement of tooth three-dimensional is controlled with this, achievees the purpose that orthodontic therapy.
Present technology bracket in use, using one or two stainless steel material thimble connection slip lid and bracket
Working method.This mode has the following problems: if domestic thimble is unable to satisfy flexibility and hard at present using a thimble
Spend the requirement that combines, it is therefore desirable to rely on import, cause that the production cost increases.If using two thimbles, first is that upper cover
It is easy to be blocked by thimble and causes to slide motionless, second is that slide into upper cover post gap big for thimble, cause swill to go to inside bracket, clearly
Reason trouble and difficulty.In addition, using thimble, the fit clearance range of the pin hole inner wall of bracket and thimble 0.01-0.04mm it
Between, otherwise can shake at thimble causes the matching loose of upper cover and bracket or thimble to insert not enter, thus to required precision
It is too high, lead to high production cost.
Utility model content
The utility model provides a kind of low production cost and can control to overcome the above-mentioned deficiency of the prior art
The locking bracket of lid and bracket connection precision.
The utility model is to provide a kind of novel bead-moving type locking bracket, and technical solution is that a kind of bead-moving type is self-locking
Bracket, including supporter groove, the slip lid with bracket mates have arch wire groove on supporter groove, are additionally provided with slip lid on supporter groove
Slot, slip lid slot intersect with arch wire groove, and slip lid is inserted in slip lid slot and is slidably matched with supporter groove, be provided on slip lid for
Fix the limiting groove for dialling pearl and for for group pearl sliding slot for dialling pearl sliding, supporter groove is provided in the corresponding position for dialling pearl sliding slot
Pearl and shell fragment hole are dialled, pearl is dialled and is fixed on elastic slice, elastic slice is set in shell fragment hole and is located at and dials below pearl, the bottom and bottom of elastic slice
Plate is in contact.The limit cooperation of supporter groove and slip lid between the two is completed by dialling pearl and elastic slice, when slip lid insertion slip lid slot first
It touching and dials pearl, spherical shape group pearl converts downward pressure for slip lid advance resistance and acts on elastic slice, and elastic slice compression both wings deform,
It dials pearl to move down, slip lid moves forward；After the first limiting groove for reaching the setting of slip lid bottom surface, dials pearl and pass through elastic slice
Slip lid is withstood in elastic force pop-up, is provided certain resistance to sliding and is positioned.Supporter groove and slip lid have opening and closing two after being assembled into
Kind state；Slip lid bottom surface is arranged two positioning and dials pearl limiting groove, and dialling after pearl slides into group pearl limiting groove just will receive resistance
It is fixed, being dialled between pearl limiting slot at two has to dial a pearl sliding slot, can reduce slip lid resistance to sliding convenient for dialling pearl at two
It is slided between limiting groove, opens to complete slip lid, is closed two states.Relative to the working method of existing thimble-type, originally
Group pearl self-locking bracket cost of utility model is lower, and locking and opening are smaller by resistance, and assembly is simple, and it is convenient to work.
Another preferred embodiment of the utility model is that supporter groove and matching for slip lid are combined into T-shaped cooperation, T-type both wings thickness

It flushes.In this way, when slip lid covers on supporter groove, what entire bracket was just generally flush with, it not will lead to and scrape skin with just uneven
Skin.
Another preferred embodiment of the utility model is, dialling pearl diameter is 0.6-1mm, dials under the justifying in shape of pearl and shell fragment hole
Side is being dialled in the hole of bead in use, dialling pearl sphere 2/3-3/4, is dialled pearl sphere 1/4-1/3 exposing and is dialled the hole of bead.The utility model uses
0.6-1mm diameter dials pearl, is suitble to the goal of the invention of the utility model, dials the shape circular upper part and square lower part of pearl and shell fragment hole, dials the hole of bead
Lower mouth width is narrow on the hole of bead convenient for dialling in pearl access aperture, dials pearl for blocking, prevents group pearl from falling off, and dials hole of bead upper end size dew
Group pearl sphere of 1/4-1/3 out is the optimum latching of the utility model and opening ratio.
Another preferred embodiment of the utility model is that elastic slice is using materials such as spring steel, ti-ni shape memory alloy；Elastic slice top
For circular groove；Elastic slice have two sides missile wing, missile wing with a thickness of 0.05-0.2mm, overall width 0.6-1mm；Two sides missile wing is
Arc-shaped, minimum range is 0.1-0.4mm between the missile wing of two sides；Elastic slice whole height 1-2mm, spring leaf can operating distance be
0.1-0.4mm.Elastic slice withstands group pearl for providing elastic force, makes to dial pearl exposing pearl and shell fragment hole aperture, provides certain resistance and rise
To the effect for limiting fixed slip lid position.
Another preferred embodiment of the utility model is that it is sliding to be respectively placed in group pearl there are two pearl limiting groove is dialled for slip lid bottom surface
The both ends of slot.Supporter groove and slip lid have opening and closing two states after being assembled into, group hole of bead of two positioning of setting on slip lid,
Dial pearl slide into dial pearl limit hole after dial pearl and bounce and be fixed by certain resistance, being dialled between the hole of beads at two has to dial a pearl
Sliding slot can reduce group pearl resistance to sliding and group pearl is slided between two limit holes, complete slip lid and open, be closed two kinds of shapes
State.
The utility model uses new-type bead-moving type structure, can be once-forming by metal injection moulding technique, relative to
Thimble working method, cost substantially reduce, and avoid the problem that swill difficulty is cleared up when thimble mode.
