The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please referring to figs. 1 through shown in Figure 6; It has demonstrated the concrete structure of the utility model preferred embodiment; A kind of dial type is locked shatter-resistant mechanism; Comprise motor 10, flying wheel 20, lock wheel support 30, lock wheel 40, braking roll 50, extension spring 60, extension spring fixed head 70 and stop plectrum 80 by motor 10 drivings, wherein:
Said lock wheel support 30 is provided with a lock wheel limited screw 31; Lock wheel 40 is installed in rotation in the lock wheel support 30 through a turning cylinder 41; This turning cylinder 41 can adopt machine tooth screw or other rod-like element; Be arranged with a lock wheel torsion spring 42 on the turning cylinder 41, an end of lock wheel torsion spring 42 is buckled on the lock wheel 40, and the other end is connected with lock wheel support 30.And; The upper edge of this lock wheel 40 also is provided with stopper slot 43, and in order to cooperate with lock wheel limited screw 31, lock wheel limited screw 31 is positioned on the stopper slot 43; When lock wheel 40 rotates; Groove by stopper slot 43 is locked the range that wheel 40 rotates to the length decision, promptly when lock wheel limited screw 31 contacts with the end of stopper slot 43, locks wheel 40 and can not continue to rotate along former direction.
Said braking roll 50 runs through lock wheel support 30; This braking roll 50 is cylindrical; Offer the grooving 51 that can tightly push down lock wheel 40 outer rims on it, an end of said extension spring 60 is fixed on through extension spring fixed screw 61 on the end of braking roll 50, and the other end of extension spring 60 is fixed on the extension spring fixed head 70; Extension spring fixed head 70 is connected with lock wheel support 30, and stop plectrum 80 is connected between the other end and flying wheel 20 of braking roll 50.
During use, braking roll 50 is tightly pushed down lock wheel 40 outer rims, stops 40 rotations of lock wheel; Realized the purpose of locked lock wheel 40, at this moment, this retaining mechanism is in locking state (like Fig. 4); Because braking roll 50 be cylindrical, anyly fall and beat caused external force and all can not be converted into revolving force, thereby lock is taken turns 40 and can not be thrown away; Prevented that this retaining mechanism from being damaged by artificial malice, improved safety to greatest extent.As shown in Figure 5, when the user controlled motor 10 to the direction of unblanking (being clockwise direction among Fig. 5) rotation, flying wheel 20 rotated bump stop plectrums 80; Stop plectrum 80 drives braking roll 50 to rotation counterclockwise; Grooving 51 on the braking roll 50 is separated with lock wheel 40 outer rims, and lock wheel 40 flicks to counter clockwise direction under 42 effects of lock wheel torsion spring simultaneously, thereby reaches the purpose of unblanking; This moment, this retaining mechanism was in unlocking condition, and extension spring 60 is stretched.When external force that lock wheel 40 is applied shown in the arrow; Lock wheel 40 moving axis 41 that rotates turns clockwise; Braking roll 50 resets under the reseting elasticity effect of extension spring 60 simultaneously; Grooving 51 on the braking roll 50 compresses lock wheel 40 outer rims again, and this retaining mechanism is realized locking once more, gets back to locking state as shown in Figure 4.
Can ensure the safety of the portable storage box of portable electronic safe, electronics gun case, electronic government documents case and other electric drive.
Be pointed out that the utility model is not that the mode that can only adopt motor 10 to drive realizes unblanking, and is as shown in Figure 6; Pull out one from stop plectrum 80 and can spur the stay cord 81 that stop plectrum 80 is rotated counterclockwise, for guaranteeing the tough and tensile intensity of stay cord 81, stay cord 81 can adopt wire rope; When need are unblanked, can be through stay cord 81 pulling stop plectrums 80, stop plectrum 80 will drive braking roll 50 and be rotated counterclockwise; The grooving 51 of braking roll 50 separates with lock wheel 40 outer rims, reaches the purpose of unblanking equally.And, rotate within the specific limits in order to limit 80 of stop plectrums, avoid unconfined rotation excessive, also a stop limiting plate 90 can be set below stop plectrum 80, this stop limiting plate 90 can be fixed on the lock wheel support 30.
This product structure is simple; The purpose that it realizes locking through the position-limiting action of 50 pairs of braking rolls lock wheel 40 because braking roll 50 be cylindrical, any fall and beat caused external force all can not be converted into revolving force; So lock wheel 40 can not be thrown away; Prevented that this product from being damaged by artificial malice, safety is high, can be widely used in portable electronic storage box/casees such as electronic safe, electronics gun case, electronic government documents case.
The above; It only is the utility model preferred embodiment; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
