Abstract
The invention discloses a variable safe deposit box lock. The variable safe deposit box lock comprises a lock box, a lock bolt and a lock cover, wherein the lock bolt is arranged in the length direction of the lock box and mounted on the internal bottom of the lock box; a short lock cylinder, a blade column and a long lock cylinder are sequentially arranged inside the lock box in the length direction; a plurality of main blades and displaceable blades stacked on each other alternately are sleeved to the blade column; the displaceable blades are mounted on the lock bolt; the displaceable blades move synchronously with the lock bolt and move up and down on the lock bolt and further are limited by a limiting pin; a customer key is matched with the displaceable blades to rotate; a master key is matched with the main blades to rotate; and a shifting fork pushing the lock bolt to perform reciprocating motion is arranged at the lower end of the short lock cylinder. The variable safe deposit box lock effectively provides lock safety and is capable of completely avoiding the probability that the key is copied. Keys with different threads can be directly replaced without demounting the lock and in the state that the lock is opened; and therefore, the variable safe deposit box lock is convenient for conventional operation. For the same lock of the same box number, keys are randomly distributed to customers and different customers never get the same key.
Description
Technical field
The present invention relates to a kind of lock for safe deposit box, relate in particular to a kind of type variable lock for safe deposit box.
Background technology
The existing safe deposit box overwhelming majority is case number (CN), and lock and a minute key all are one to one, because after the client rents, minute key is always in client's hand, so the protection of key can't be effectively controlled, and is easy to by fraudulent copying.Minute key of this lock is just as a fixing password, but that password is unalterable, has potential safety hazard, in case be replicated, can be subject to many one heavy danger on the safety of safe deposit box.
Also having a kind of is the key type variable, refers to that same lock can use without key, greatly promotes the safety factor of lockset, but trivial operations when changing key needs the professional to use special tool to adjust lockset, and operation is unfavorable for routinizing.Such as the patent of existing application, application number is as follows: CN201020156166.X, CN201020149663.7.
Summary of the invention
The present invention seeks to provides a kind of type variable lock for safe deposit box for the defective that prior art exists.
The present invention adopts following technical scheme for achieving the above object:
Type variable lock for safe deposit box of the present invention, comprise lock box, dead bolt and locking closure, dead bolt is in the setting of lock box length direction and be installed on the lock box inner bottom part, lock box inside sets gradually short lock core, vane posts and long lock core along its length, cover has multi-disc primary blades and the displacement blade that is stacked alternately on the vane posts, the displacement blades installation on dead bolt, displacement blade and dead bolt synchronizing moving and dead bolt move up and down and by spacer pin spacing; Client's key cooperates rotation with the displacement blade; Master key cooperates rotation with primary blades; Short lock core lower end arranges and promotes the shift fork that dead bolt moves reciprocatingly.
On the described displacement blade stator is set also.
Described multi-disc primary blades and displacement blade are 7.
All establish the suppressing device that suppresses at the lock box inwall on described multi-disc primary blades and the displacement blade.
The safety of effective supply lockset of the present invention, the possibility that can avoid key to be replicated fully.Under the prerequisite that does not unload lockset, under the lockset opening, can directly change the key of different tartars, be convenient to routine operation.Because same lock on the same case number (CN), giving client's key all is randomness, is same never.
Description of drawings
Fig. 1: structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the type variable lock for safe deposit box, comprise lock box 1, dead bolt 2 and locking closure 3, dead bolt 2 is in lock box 1 length direction setting and be installed on lock box 1 inner bottom part, lock box 1 inside sets gradually short lock core 5, vane posts and long lock core 4 along its length, cover has multi-disc primary blades 8 and the displacement blade 9 that is stacked alternately on the vane posts, and displacement blade 9 is installed on the dead bolt 2, and displacement blade 9 and dead bolt 2 synchronizing movings also move up and down and spacing by spacer pin 7 at dead bolt 2; Client's key 10 cooperates rotation with displacement blade 9; Master key 12 cooperates rotation with primary blades 8; Short lock core 5 lower ends arrange and promote the shift fork 6 that dead bolt 2 moves reciprocatingly.
On the described displacement blade 9 stator 11 is set also.
Described multi-disc primary blades 8 and displacement blade 9 are 7.
All establish the suppressing device that suppresses at lock box 1 inwall on described multi-disc primary blades 8 and the displacement blade 9.
Operating principle of the present invention is as follows:
Under the state that master key 12 is opened, client's key 10 inserts lock core hole, the tartar that drives clockwise the different height on 6 rotation while of the shift fork key 10 drives the different angle of primary blades 8 rotations makes the breach of primary blades 8 front portions all aim at the convex of spacer pin 7 (convex can enter breach), that punctual shift fork 6 is namely begun to drive dead bolt 2 is mobile backward when breach and convex, dead bolt indentation this moment lock box, lockset is opened.
The principle that the present invention changes key is as follows:
(lock core Rotate 180 ° under the opening of lockset, client's key 10 can be extracted, the key that changes another different tartars inserts), the convex that the front end displacement groove of displacement blade 9 has broken away from spacer pin 7(displacement this moment blade 9 rear ends all enters the front end breach (can move up and down at dead bolt 2 this moment with primary blades 8) of primary blades 8, when key is rotated counterclockwise, the tartar of different height on the key drives primary blades 8 and displacement blade 9 is adjusted to corresponding height, this moment, shift fork 6 promotion dead bolts 2 moved toward the outside of lock boxes 1, displacement groove according to displacement blade 9 front portions after the displacement of key tooth flower height enters spacer pin 7, lockset cuts out (height of displacement this moment blade 9 is adjusted according to the tartar of key), as opening, the key that used in the time of must being closed by last time just can be opened again.
