Abstract
The utility model relates to a force unlock structure for a safe, comprising a lock head, a gear and rack transmission mechanism, a sliding plate, a lock body, etc. The utility model is characterized in that a lock core with low mutual-unlock rate and a cross slot drives a small gear and a bull gear to rotate so as to drive a rack and pull the sliding plate, and the lock body is oppositely moved. The force unlock structure for the safe can make a lock bolt quit a lock hole and open a door under the conditions that an electronic system is completely broken and has no power, a cipher is forgotten, the safe is largely twisted and deformed under the action of the outer force, etc. The utility model has the advantages of simple structure, strong safety, convenient opening, low cost, etc.
Description
The utility model belongs to the category of haberdashery and hardware product, promptly is that safety cabinet is forced unlocking mechanism.Its effect is malfunctioning or forget under the situation of password in electronic system, reliably the opening safety cabinet.
At present, forcing the unlocking mechanism reliability not high both at home and abroad, use inconveniently, is by peripheral hardware one electronic chip input impressed current as the pressure unlocking mechanism of " two dog " board Electronic safe, drives the motor-driven bolt.This mechanism belongs to electronic system fully, if this system breaks down, can not open, and it is perfectly safe to guarantee, its reliability reduces greatly.The peripheral hardware of this product is forced the relative mutual opening rate height of lockaid gun in addition, and confidentiality is poor.
" aviation " board safety cabinet is to use the armstrong's patent lock, add the electromagnet backing pin of a digital control, this pressure unlocking mechanism is with a simple and mechanical device, forces to depress the electromagnet pin, stirs the bolt motion with mechanical key again, the opening safety cabinet, though this mechanism is reliable, and is poor with the safety of standard machinery key, the mutual opening rate height, use inconvenience, be not suitable for the needs in high-grade place.
" MMD " type safety cabinet is similar with " aviation " board, and difference is that its pressure mode of unblanking is to be forced to unblank by external world's emission infrared rays.Be that electronic system is sent signal, depress electromagnet, open the door with hand-lifting is moving again.Yet, in case the electronic system of forcing to unblank is out of order, just can not open, it is perfectly safe to guarantee.
World-renowned hotel safety cabinet, Norway produces the pressure unlocking mechanism of ELSAFE board computer safety cabinet, then to dismantle the keypad on the door earlier, pass through transmission mechanism with a private key, the pressure dedicated gear of unblanking is engaged on the tooth transmission chain of motor lock bolt, inserts in the gear axis hole with common hex(agonal)screw cutter, hand-turning forces to unblank dedicated gear, drag whole driving-chain counter motion, finish enforced opening.Reset then will by after implement aforesaid operations forward, trouble very.
The purpose of this utility model is, problem at above existence, design and a kind ofly can forget password, break down or outage for a long time in any position of electronic system, battery does not have electricity and can't recharge, even safe body can guarantee that still lock bolt withdraws from lockhole, the unlocking mechanism of unlatching cabinet door under big external force effect torsional deformation situation.And do not influence safety, the security performance of safety cabinet, accomplish that again mechanism is simple, operation is reliable, and it is convenient, with low cost to open.
The new purpose of this practicality solves by following proposal:
Lock core on the tapered end has a cross recess, the cross head key that lock core adapted mutual opening rate is extremely low.Pinion is fastened on the lock core, pinion and gear wheel engagement, and gear wheel meshes with tooth bar again, and respectively there is a supporting base at the two ends of tooth bar, and an end is fixed, and the other end can be movable in the supporting base hole.Fix the supporting base and the slide plate fixed connection of an end, lock body is fixed on the slide plate, and moving of slide plate drives lock body and move, thereby bolt on the lock body is advanced or retreats, and realizes unblanking and the locking effect.The tapered end that is exposed at the safety cabinet outside is covered with the drawer type plate, and plate and surface cover fuse, from can't see tapered end and key hole in appearance.
Another scheme of the present utility model is to replace big pinion with an eccentric wheel, replaces tooth bar with a connecting rod, realizes that the lock core that key drives on the tapered end rotates, lock core drives eccentric wheel and rotates, eccentric wheel drives slide plate by connecting rod and moves, and slide plate drives lock body and moves, and opens thereby the realization lock bolt closes.
The 3rd scheme of the present utility model is that lock core and reel are fixedly connected, one end of reel and wire rope is fixed, the other end and the slide plate of wire rope are fixed, a compression spring is arranged between slide plate and the door-plate, lock core on tapered end rotates and drives the reel rotation, and wire rope is on reel, thus pulling slide plate and lock body, the compression spring unclamps bolt.After the lock core revolving force unclamped, under the effect of spring force, slide plate automatically reset, and lock bolt inserts in the lockhole, and is locked insurance.
The utility model has the advantages that and removed the current clutch apparatus that designs that retreats for the realization lock bolt commonly used from, pure frame for movement, hand drive, in electronic system fully under destruction, non-transformer, the situation such as forget Password, opening safety cabinet reliably, and do not destroy cabinet, even safe body is subjected to big external force effect torsional deformation, can guarantee that still lock bolt withdraws from lockhole, open the cabinet door.So mechanism is simple, strong security, it is convenient, with low cost to open.
