Description

The dual fail-safe key-type mechanical puzzle lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of dual fail-safe key-type mechanical puzzle lock.

Background technology

In on April 2nd, 2003 disclosed Chinese patent bulletin CN2542778Y, a kind of " mechanical code lock " disclosed, it is by lock body, dead bolt, reset button, knob and lock core are formed, one chute is set on lock body, motion bar is installed in the chute, on the both sides of motion bar, respectively be provided with more than one pawl, movable steel disc is placed on the motion bar, in the button hole that the both sides of lock body upper hopper chute are provided with, lock core is set, be provided with draw-in groove at lock core body, the draw-in groove opposite is provided with a lower bayonet slot on lock core body, respectively is provided with a small boss on the planar slot of the two sides of lock core body.The shortcoming of this coded lock is that applicable surface is little, as for the not high elder person of memory, in case forgotten that password just is difficult to unblank.

Summary of the invention

The purpose of this utility model is the problem that can not open after the forgetting Password of existing in the existing password lock in order to solve, and a kind of easy to use, simple in structure, both available password unlocking dual fail-safe key-type mechanical puzzle lock that also can open the lock with the key is provided.

Technical scheme:

The purpose of this utility model is achieved in that a kind of dual fail-safe key-type mechanical puzzle lock, comprise coded lock and mechanical lock, wherein the mechanical lock side of being provided with tongue and tiltedly tongue, the oblique tongue that it is characterized in that described mechanical lock links by square bar and the interior handle that is installed in an inboard, keyhole on the tapered end of described mechanical lock exposes to outer side of door, the square shaft of described coded lock links with the outer handle that is installed in outer side of door, it is coaxial with the square shaft of described outer handle that the front end of described square bar passes mechanical lock, on the square bar front end face, be provided with eccentric pylon, the inner of described square shaft is provided with shifting block, and this shifting block is positioned at the pylon rear side of described square bar.When accessing to your password lock, coded lock is only controlled the oblique tongue in the mechanical lock, when unlocking cipher is correct, can forward rotation outer handle, stir pylon on the square bar by the shifting block on the square shaft that links with outer handle, square bar is rotated, and the oblique tongue that square bar drives mechanical lock bounces back in the mechanical lock lock body and unblanks, and a need can be controlled the pass of oblique tongue at any time by interior handle or open in door; When unlocking cipher was incorrect, the traveller on the coded lock was pushed down the dop of outer handle and can not be rotated outer handle, can not unblank, in case forget unlocking cipher, can use key by tapered end the oblique tongue of mechanical lock to be opened outdoors; If owner goes out the time longer, and when need to strengthen taking precautions against, close behind the door, can by tapered end the square tongue in the mechanical lock also be locked with key, at this moment, even unlocking cipher correctly can not be opened square tongue, realize dual fail-safe, have only with correct key and just can unblank.

Described dual fail-safe key-type mechanical puzzle lock is characterized in that described square shaft front end is provided with coaxial cylinder, described square bar end be provided with square shaft on the hole that matches of cylinder.Also promptly on square shaft and square bar opposing end faces coaxial cylinder is set respectively and the hole matches, its effect is to make square bar and effectively coupling of square shaft.

Described dual fail-safe key-type mechanical puzzle lock is characterized in that described tapered end the inner is provided with turn-knob, and square tongue and oblique tongue that this turn-knob is positioned at an inboard and described mechanical lock link.Its effect is can be at any time by the control of this turn-knob to the square tongue and the oblique tongue of mechanical lock in door.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, both available password unlocking also can open the lock with the key, to liking people with the coded lock lock that can access to your password, the people who dislikes coded lock can make and open the lock with the key, and the user can change unlocking cipher at any time, the authority of password unlocking is confined to the crowd that the user allows, and wish not allow sometime anyone when unblanking outdoors as the user, can be in door by turn-knob or locking with the square tongue of mechanical lock with key outdoors, this dual fail-safe key-type mechanical puzzle lock is simple in structure, easy to use.
