Abstract

The utility model relates to a keying cipher lock, which is composed of a box body, a cipher seat, a mechanical cipher mechanism, door bolts, a lock head, etc. The utility model is characterized in that the upper of the lock head is provided with seven holes along the periphery of a key hole, wherein, six of the seven holes are provided with six keys 33, and the cipher mechanism on the cipher seat is controlled by a positioning hole 29 on a main door bolt 4; one of the seven holes is provided with a key 32 which drives a recovery knife 26 to press downwards, and the cipher mechanism comes back to the encoded initial position. The utility model has the advantages of a spring lock, also has good safety effect, a key can not be imitated by other people when the key is lost, and the lock still has the safety effect.

Description

Keying cipher lock

The utility model relates to a kind of button-type mechanical password device of locking of locking and be used for, and it is made of parts such as box body, password seat, mechanical cipher mechanism, keeper, tapered ends.

In the widest mechanical lock of public use at present, as pin tumbler lock, though their profiles are different, its important structure is identical.Here it is inserts lock core to the key that is shaped on tooth more different in size, cooperates the length pellet shot from a slingshot in the lock core.It is smooth to form the lock core circumferential surface, lock core can be rotated in tapered end to the left and right and realize the start or stop function of such lock, this class is latched in following defective: 1, a kind of key of profile of tooth can only be driven a dozen locks, and 2, the user need carry key, once key loss, just may be by imitated; 3, safety coefficient is poor, in 2450 times runin, has at least more than 5 times and can open mutually.

The purpose of this utility model is to provide a kind of and both can acts on key separately and close the door, and can access to your password again to cooperate key operated key cipher lock.It not only possesses the advantage of existing cylinder lock, and its security personnel are effective, even lose key, also is not afraid of by other people and copies, and lock does not still lose security personnel's effect.

The utility model is realized above-mentioned purpose, the scheme that adopts is on the tapered end 5 of existing lock (as ox head board door lock), around keyhole 36, open 7 holes, wherein 6 buttons 33 are installed in 6 holes, by the Cipher mechanism on the 29 control password seats 2 of the locating hole on the main keeper 4, another hole is installed in button 32 driving recovery cuttves 26 and presses down, and makes Cipher mechanism get back to the initial position of coding; Described main keeper 4 has three passwords and opens and closes groove 38, setting-in gear 30 between its stationary rack 37 and the movable tooth bar 27; Its cipher wheel 18 of described Cipher mechanism, ratchet 19, cam 20 are an integral body, and ratchet 19 contacts with ratchet 16, cam 20 is dialled cutter 17 with recovery and contacted.

Be further described below in conjunction with accompanying drawing:

hole

28,29, connect press key pole 33 and driving lever 21, works the connecting rod effect that presses down.

Fig. 7: be the lock shape structural representation of the utility model key cipher lock; It is characterized in that around keyhole, having seven holes, 7 buttons are installed.

Fig. 1,2,3,4,5,6,7 or Fig. 1 and Fig. 8: the integral installation distribution structure of having showed the utility model key cipher lock.The box wall inboard of box body 1 clamps password seat 2; Cipher mechanism is that axle 13 two ends that the integral body that three covers are made of cipher wheel 18, ratchet 19, cam 20 is installed are plugged in respectively among the hole 12 and hole 10 on the password seat 2, axle 14 suits restore dials cutter 17, axle 15 two ends that cutter 17 is dialled in suit three cover ratchets 16 and recovery are plugged in respectively among hole 11 and the hole 9, ratchet 19 contacts with driving lever 21, and three integral body are installed the another side of password seat 2 equally and three ratchets 16 are dialled the Cipher mechanism that cutter 17 is formed with recovery; Restore cutter 26 and be loaded among the recovery cutter groove 24 that is lined with spring, the following spring 22 that equally also is equipped with of driving lever 21, horizontal with password seat 2; Main keeper 4 is placed on the password seat 2, and its three passwords open and close grooves 38 and snap in the cipher wheel 18 in the Cipher mechanism and match with it; Attached keeper 3 is installed identical with prior art, passes hole 6 to the hole 7 on the box body 1, is positioned on the box wall by spring 45 and spring leaf 41, plays reset response, by buckle 42 and main keeper 4 open in the lump; Reset key 32 on the tapered end 5 restores cutter 26 by the garden cylindricality pellet shot from a slingshot control in the recovery button locating hole 28 on the main keeper 4, six password keys 33 on it are by the garden cylindricality pellet shot from a slingshot in 6 password key locating holes 29 on the keeper 4, by driving lever 21, control ratchet 19, its lock core 35 insert the centre bore 31 of main keeper gear 30 by connector 34.By this connection, formed the utility model key cipher lock.

This press-key lock coded lock is to realize its function like this:

At first press reset key 32, the inclined-plane, both sides that orders about the cutter 26 that resets presses down, and squeezes moving movable axis 14, open ratchet 16, make simultaneously to restore to dial on the cutter 17 and lift, stir cam 20 and turn to the plan-position, make cipher wheel 18 and ratchet 19 get back to the initial position of coding (or title clear " 0 ").

Then, key is inserted lockhole 36, and press 6 buttons 33 one by one according to given password, drive 6 driving levers 21 by the garden cylindricality pellet shot from a slingshot in 6 password key locating holes 29 on the main keeper 4, stir 6 ratchets 19 one by one, make password 18 forward straight angle position to, the password that breaks away from the main keeper 4 from longitudinal direction opens and closes groove 38; Turn key again, by lock core 35 and connecting rod 34, transmitting gear 30 along tooth bar 37, drives main keeper and retreats, and buckles 42 simultaneously attached keeper driven, and two keepers are opened immediately, and door has also just been opened.

Continue the turn key, main keeper drives attached keeper 3 to be continued to retreat, buckling on the attached keeper 3 42 acts on box body hole 6 right hand edges, because buckling 42 is inclined-planes, make attached keeper 3 left extrusion spring sheet 41 buckle 42 44 places that break away from fully on the main keeper 4 until attached keeper 3, before once more attached keeper 3 being pushed to by spring 45, its effect is identical with the attached keeper effect of the pellet shot from a slingshot Lock with double safety guard of prior art.

Go out at closing time two kinds of methods:

First kind, the method of closing the door accesses to your password: at first key is inserted lockhole 36, the turn key, by lock core 35 and connecting rod 34, transmitting gear 30 is along tooth bar 37, driving main keeper 34 advances, make it to be in bolt door state (position),, rely on buckle 42 44 the positions that reset to main keeper 4 of elastic force attached keeper 3 simultaneously by being positioned at the spring leaf 41 that box is warded off.

Press reset key 32 then, order about the cutter 26 that resets and depress, squeeze moving movable axis 14, open ratchet 16, make simultaneously to restore to dial on the cutter 17 and lift, stir cam 20 and turn to the plan-position, make cipher wheel 18 and ratchet 19 get back to the initial position of coding.The password that makes cipher wheel 18 forward main keeper 4 to from longitudinal direction opens and closes in the groove 38, and door promptly shuts.

Second kind, use the key method of closing the door separately without password: this method of closing the door only needs key is inserted lockhole 36, again the turn key, by lock core 35 and connecting rod 34, transmitting gear 30 is along tooth bar 37, drive main keeper and advance, make it to be in bolt door state (position), door promptly shuts.Need not press reset key 32, cipher wheel 18 still is in straight angle position, and the password that still breaks away from the main keeper 4 from longitudinal direction opens and closes groove 38.Only need turn key when opening the door next time, need can not open door by cryptographic key 33.
