CN2169670Y - Key controlled mechanical puzzle spring lock - Google Patents

Abstract

The utility model relates to a mechanical cipher spring lock which is controlled by a key. A cipher driving assembly (7) is provided with a sleeve barrel (7-1) which is driven by a lock core (2) and a sleeve-barrel connection rod (7-2). The sleeve-barrel connection rod (7-2) drives a cipher structure assembly (6). When the cipher is relieved or the cipher is not needed, a key handle is vertically inserted by the book method, a key is rotated, a lock-core connection rod (4) is rotated to drive a lock tongue, and the sleeve barrel (7-1) is not rotated. When the key handle is inserted horizontally, the key is rotated, both the lock core (2) and the sleeve barrel (7-1) are rotated, and the cipher is given or is relieved. The lock can not be opened by that the lock core (2) is bored off or a lock head is pulled off.

Description

Key controlled mechanical puzzle spring lock

The utility model relates to coded lock, relates in particular to a kind of mechanical cylinder lock with key control password.

The combination disk of general insurance cabinet lock and daily mechanical code lock, other people can stir, even can the malice examination dial the crime of combination disk technology, and the anti-drilling property of lock core is poor, less reliable.

The purpose of this utility model is to provide a kind of improved key control mechanical password bullet lock at above-mentioned deficiency.

The purpose of this utility model is achieved by following scheme.It comprises by key, can two orientation inserts key guide 1, lock core 2, lock body 3, lock core connecting rod 4, pellet shot from a slingshot 5, cryptography architecture assembly 6, password driven unit 7, password display module 8, dead bolt element of construction 9 and the dead bolt driven unit 10 of key at least.The difference with the prior art feature is a password driven unit 7, be provided with sleeve 7-1, bush connecting rod 7-2, when key is pressed direction initialization X insertion, lock core 2 and sleeve 7-1 engagement, sleeve 7-1 is connected with bush connecting rod 7-2, bush connecting rod 7-2 connects cryptography architecture assembly 6, pellet shot from a slingshot 5-2 is arranged in the sleeve 7-1, when key is pressed direction initialization Y insertion, it is concordant with sleeve 7-1 contact surface with lock core 2 that pellet shot from a slingshot 5-1 in the lock core 2 and pellet shot from a slingshot 5-2 in the sleeve 7-1 contact end face, screw key, lock core 2 and lock core connecting rod 4 rotations, flexible in order to drive dead bolt, sleeve 7-1 and bush connecting rod 7-2 do not rotate, thereby cryptography architecture assembly 6 does not rotate.And key is when pressing direction initialization X and inserting, it is concordant with lock body 3 contact surfaces with sleeve 7-1 that pellet shot from a slingshot 5-3 in the lock body 3 and pellet shot from a slingshot 5-2 in the sleeve 7-1 contact end face, screw key, lock core 2 and lock core connecting rod 4 rotations, sleeve 7-1 and bush connecting rod 7-2 also rotate, bush connecting rod 7-2 drives 6 rotations of cryptography architecture assembly, and reaching can be by password unlocking.Cryptography architecture assembly 6 can be made up of password thumb wheel 6-1, password disk 6-2 etc., on password thumb wheel 6-1 and the password disk 6-2 block piece of connection 6-3, block piece hole 6-4 and recess 6-5 are arranged, bush connecting rod 7-2 is connected with password thumb wheel 6-1, password thumb wheel 6-1 drives password disk 6-2 by connecting block piece 6-3, block piece hole 6-4 is used for changing and connects the position of block piece 6-3 on password thumb wheel 6-1 and password disk 6-2, and purpose is to change password.Dead bolt driven unit 10 comprises by gear 10-1, idle wheel 10-2, handsetting gear 10-3, idle wheel 10-2 and handsetting gear 10-3 are normal engagement, two axle center are fixed on the sheet metal 10-4, vertical projection 10-5 and spring 10-6 are arranged on the sheet metal 10-4, when password mixed up, projection 10-5 was over against recess 6-5, and under the effect of spring 10-6, projection 10-5 enters recess 6-5, gear 10-1 and idle wheel 10-2 engagement.Lock core 2 rotations drive dead bolt element of construction 9 by lock core connecting rod 4, gear 10-1, idle wheel 10-2, handsetting gear 10-3.During password setting, projection 10-5 at least with recess 6-5 in a dislocation, projection 10-5 is pushed at the password thumb wheel 6-1 or the password disk 6-2 edge of recess 6-5 dislocation open, gear 10-1 is separated with idle wheel 10-2, screw key, gear 10-1 rotation, idle wheel 10-2 does not change.Can adopt key bit is the axial symmetry cross key, and pellet shot from a slingshot 5-2 in pellet shot from a slingshot 5-1, the sleeve 7-1 also is an axial symmetry in the lock core 2 correspondingly.Open the lock with the key like this, when key inserts key guide 2, only distinguish the vertical and two kinds of situations of level of the shank of the key, and do not note difference four orientation insertion keys up and down.Password display module 8 can be carved with azimuth mark 8-1 at lock core 2 and sleeve 7-1 surface, and surface of lock body is carved with combination disk 8-2.

The utility model is compared with the existing mechanical password night lock and had the following advantages: (1) password can not arbitrarily be stirred, and prevents other people malice technology crime; (2) adopt password driven unit and lock core to control the dead bolt motion jointly, have only key or only grasp password and all can not remove password or unblank, even drilledly remove lock core or transfer to tapered end also can't unblank; (3) in the time need not password being set,, therefore can be applicable to daily various locksets such as door, cabinet, motorcycle with the same operation of common spring lock.

Accompanying drawing is the disintegration state phantom drawing that the utility model is made family expenses door lock embodiment.

Embodiment below in conjunction with accompanying drawing makes an explanation to the utility model.

Adopt cross key, and setting the Y direction, to be inserted as the shank of the key vertical, and key is inserted key guide 1, screw key, lock core 2 rotations, sleeve 7-1 does not rotate, and directions X is inserted as the shank of the key level, key is inserted key guide 1, screw key, lock core 2 and sleeve 7-1 rotate synchronously.Its key bit axial symmetry of first wife's cross key.

It is identical with the common spring door lock that password mixes up back switching latching operation.The Y direction is inserted key, and screw key, lock core 2 drive lock core connecting rod 4, gear 10-1, idle wheel 10-2, handsetting gear 10-3 rotation successively, and handsetting gear 10-3 drives the dead bolt motion.

Password is set.Directions X inserts key, suitable, counter rotation is several times behind the key, lock core 2, sleeve 7-1 rotate synchronously, sleeve 7-1 drives password thumb wheel 6-1 and password disk 6-2 rotation by bush connecting rod 7-2, connection block piece 6-3, projection 10-5 is pushed at the edge of password thumb wheel 6-1 password disk 6-2 open, make idle wheel 10-2 leave gear 10-1, just set password.The password not match even key is arranged, X or Y direction are inserted original key, screw key, lock core 2 and gear 10-1 rotation, but idle wheel 10-2 and handsetting gear 10-3 do not rotate.Or even malice bores and to remove lock core 2 or to transfer to tapered end, and the rotary locking cylinder tie rod holes also can only make gear 10-1 rotation, and idle wheel 10-2, handsetting gear 10-3 can not rotate.

The password setting back pullout (BPO).During if any two password disks, at first directions X inserts key, more than clockwise direction screw key three circles, then according to password, clockwise → counterclockwise → the clockwise azimuth mark 8-1 that makes for three times aims at number on the combination disk 8-2 respectively, projection 10-5 enters password thumb wheel 6-1 and password disk 6-2 breach 6-5, idle wheel 10-2 and gear 10-1 engagement.Extract key again, the Y direction is inserted key, and screw key drives dead bolt by lock core 2, lock core connecting rod 4, gear 10-1, idle wheel 10-2, handsetting gear 10-3 etc., realizes unblanking.

Processing methods such as the utility model parts adopt conventional casting, mill, brill, car, punching press, dress screw are made, and few parts is outsourcing piece and standard component.Tapered end is installed lock spring 5-3 and marble spring earlier, refills upper bush 7-1 and sleeve pellet shot from a slingshot 5-2, loads onto lock core 2 and lock core marble 5-1 then, loads onto bush connecting rod, lock core connecting rod 4 etc. at last.
