The utility model has the advantages of simple structure, firmness and durability, large quantity of code setting, convenient code programming and changing, uneasy breaking, low price and convenient using. The utility model can be applied in the office and the family, the security door and the safe, relieving the trouble for people to bring the key inconveniently and to lose the key, and thus the utility model is a substitute of the ordinary mechanic lock and the coded lock. At present, no product alike is available at home and abroad, so the utility model has great application and using value in the market at home and abroad.
Description
But the utility model relates to a kind of mechanical lock of private code.
In the prior art, general door lock uses various key control lock cores to unblank the mutual opening rate height, key is easily lost and is copied, and general coded lock, number of password is few, need rotation to check the number, easy sensed number is changed password inconvenience, in case forget Password then feel simply helpless, be difficult to independent use, thereby, adopt the multi line insurance mode of key lock encrypted code lock in important events, but above-mentioned technological deficiency is difficult to still solve more.
The purpose of this utility model provides the self-editing key theftproof lock of a kind of available password or key unlocking.
The utility model is achieved in that a kind of cipher key locker is connected by lock body switching mechanism and cipher key locker core mechanism and forms.The lock body switching mechanism can adopt the opening and closing structure of general door lock.The key lock core comprises core body fixed cover, spacer, alignment pin, weak point pin, graduated circle, the Cipher mechanism of compositions such as a yard ring, spring, interlock cover, linkage pin, ring washer and the lock core mechanism that is made up of driver blade, interior outer lock core, internal cylinder ring washer, outer lock core back-up ring, keyhole spring, keyhole plug, pellet shot from a slingshot pin, lock core cover etc. is overlapped, becomes in sign indicating number circle, dialing.The cipher key locker core mechanism is connected with the lock body switching mechanism by the core body fixed cover, have a centre bore on the spacer and be fixed together with the core body fixed cover, have a locating slot in its centre bore, have on the spacer two rows by certain radial distance distribute to code holes, wherein a row and locating slot are on same straight line, and the quantity of every round is with identical to the quantity of sign indicating number circle.Chip is nestled up spacer place, have the hole slot identical on it, on circumference, by certain angle 30～100 calibration holes that distributing to several different-diameters of an end face of chip with spacer.Be close to chip overlapped from inside to outside and putting several graduated circles and the sign indicating number circle, each is being provided with two protruding pin and a pair of radial slots to sign indicating number usefulness to the sign indicating number circle near on the end face to chip, corresponding on the position of protruding pin and the spacer to code holes, other end to the sign indicating number circle is provided with a circle change sign indicating number hole, and quantity is corresponding with the calibration hole on the spacer with the position.Each graduated circle is sleeved in the sign indicating number circle, has the locating convex block of two symmetries to insert in the radial slot to the sign indicating number circle on its outer garden face, between two circles spring is housed.Each graduated circle with the end face that chip is contacted on be arranged with two with calibration cheat the protruding pearl of corresponding semicircle.Dialing is with three～four, be sleeved on the outer lock core successively from inside to outside, rotatable between each cover, at skin dialing cover, become be symmetrical arranged on sign indicating number ring and the end face that the sign indicating number circle is contacted two with the change sign indicating number on the sign indicating number circle is cheated the protruding pearl of corresponding semicircle, embedding is to forming the fast code changing structure in the hole of the change sign indicating number on the sign indicating number circle, have two pin-and-holes on the axial end of other internal layer dialing covers, on the end face of the change sign indicating number ring relative, fixing two short pins that can insert in the pin-and-hole with it, rotation dialing cover can drive the calibration of sign indicating number circle by calibration hole on the graduated circle carried out sign indicating number, when number that the Zhengyuan is set, each to the protruding pin on the sign indicating number circle just aimed on the chip to code holes, promote the handle protecgulum or dial to overlap each protruding pin to the sign indicating number circle is entered in the code holes, simultaneously, internal layer to the sign indicating number circle by the back-up ring on the adapter sleeve and two linkage pins being fixed thereon, in the drive, outer lock core moves axially, make the alignment pin that is fixed on outer lock core the inner be pushed away locating slot on the spacer, lock core and driver blade can rotate with handle and unblank.
When inserting key unlocking, can rotate mutually between the interior outer lock core, drive driver blade by key and unblank.If forgotten password or password entanglement, can insert key, by the internal cylinder cannelure promote linkage pin, interlock cover, to the sign indicating number circle, become the code structure of looking for that sign indicating number ring, back-up ring form, stir the dialing cover from inside to outside step by step, make two protruding pins on the sign indicating number circle are found accordingly code holes, thereby give correct password for change.When revising password, stir each dialing earlier and put predefined password, insert key and promote internal cylinder to mark place, location, each is passed accordingly to code holes the protruding pin on the sign indicating number circle, enter in the change code holes on the spacer, at this moment, the sign indicating number circle is fixed, rotate the dialing cover more one by one, make certain number that respectively puts align the location mark, can obtain new password, after the lock core of loosing one's grip resets, dial disorderly each dialing cover, finish the sign indicating number work of adapting.The password combination of this lock has M
NKind, the number number that M puts for dialing, N works as M=100 for the quantity of dialing cover, and during N=4, the probability of unblanking is X=1/100
4, promptly 1/100000000th.Generally select X=1/50
3=1/125000 has been enough.
Advantage of the present utility model is: 1, available password or key unlocking, the user can number sign indicating number at any time, adapts the number simple and fast.2, number of password is big, and number is easily remembered.3, be not afraid of and forget Password and mess code, can give password for change with key when occurring forgetting yard, former mechanical code lock can't be accomplished this point.4, lock is rational in infrastructure, can't unblank with the method dialing of sensing.5, simple in structure, sturdy and durable, cheap, applied widely, especially be fit to places such as hotel, office.
