Abstract

Disclosed is a double-key code lock, relating to a door lock, which is an improvement on the technical basis of the original door lock. The original door lock comprises a lock shell (1), a lock bolt (3), a lock bolt coupling mechanism (4), a latch bolt (2), a lock core (9) and a key (8), and can be opened by a key to be inserted into the lock core and be rotated. The novel design increases an auxiliary lock core and a key (10) thereof, a code wheel (6) and a lock bolt cross board (5); one end of a code wheel shaft (7) is provided with screw threads matched with screwed holes on the lock case, and the part extending out of the lock case of the code wheel shaft is provided with a handle (13), the other end of the shaft is provided with a fork opening and matched with the pull piece (12) of the auxiliary lock core, the outer edge of the code wheel is provided with a broadbrimmed wheel rim on which a gap is arranged, a lock bolt forked plate is fixedly arranged on the lock bolt in the lock case, an opening is arranged on the lock bolt forked plate, and the opening of the lock bolt forked plate is matched with the gap on the broadbrimmed wheel rim of the code wheel. The code lock is easy to set and convenient in use, and is safe and reliable.

Description

Two spoons of coded locks

Technical field

The utility model relates to a kind of door lock, i.e. improvement on original door lock technical foundation.

Background technology

Door lock originally includes lock housing, dead bolt, dead bolt link gear, windproof dead bolt, lock core and key, inserts the lock core rotation with a key and just can open door lock.If someone usurps key or is furnished with identical keys, enter the house just can open door lock, this lock fails to play effective antitheft effect.

Summary of the invention

The purpose of this utility model is a kind of lock that has password of design, cooperates just with key and can open door, reaches antitheft effect.

The technical solution of the utility model is, in original lock housing, dead bolt, the dead bolt link gear, windproof dead bolt, on the basis of main lock core and key, auxiliary lock core and key have been increased, cipher wheel and dead bolt fork plate, the cipher wheel center has axle, axle is fixed as one with cipher wheel, one end of axle is threaded and cooperates installation with screw on the lock housing, the other end of axle has prong, cooperate with the plectrum of auxiliary lock core, the outer rim of cipher wheel has the broadside wheel rim, has breach on the broadside wheel rim, and dead bolt fork plate is fixedly mounted on the interior dead bolt of lock housing, have opening on the dead bolt fork plate, dead bolt fork plate opening cooperates with breach on the cipher wheel broadside wheel rim.

The key of main lock core can be identical with the key of auxiliary lock core, also can be inequality.

The threaded end of password wheel shaft is stretched out the handle that is partly with outside the lock housing.

During use, lock is installed on the door, shuts the anti-dead bolt that takes two turns of goalkeeper's main lock core key and stretch out on the door lock, dead bolt fork plate has also broken away from cipher wheel simultaneously, changes the X circle with the auxiliary lock core key by the direction of anticipation again, setting code, and cipher wheel and dead bolt fork plate mouth interlace.If there is lawless people to attempt to open the door, even he has key, do not know that cipher wheel changes several circles, also can't open lock.The Shi Yaoxian that normally unblanks oppositely changes X circle with key with auxiliary lock core, again with key with main lock core Unscrew door lock.

This coded lock is set easily, and is easy to use, safe and reliable.On original technical pattern basis, improve, the content that develops skill, general lockmaking enterprise all can make production, increases the business economic benefit, strengthens the social safety degree.
