Description

Anti-riot coded lock

The utility model belongs to a kind of coded lock, especially integrates safe, the insurance of password and mechanical lock characteristics, anti-riot coded lock by password and machinery connection interlocking.

Existing railway freight railway carriage, freight container, warehousing warehouse, bank vault etc. all adopt password night lock or dual fail-safe pin tumbler lock.Password night lock adopts lever principle, feel reaction and slight sound is arranged, easy stolen lock when unblanking; The dual fail-safe pin tumbler lock is a utilization pellet shot from a slingshot core and the principle of fixing pellet shot from a slingshot carrier interlocking is unblanked with locking, after key inserts lockhole, movable pellet shot from a slingshot core is disengaged with fixing pellet shot from a slingshot carrier interlocking, and key drive activity cylinder lock transmission bar in the heart rotates flexibly to be controlled dead bolt and unblank.This class door lock also is easy to stolen lock because the variation of key piece breach is limited, and burglary insurance is not strong, and key is easily lost preparation simultaneously.

The purpose of this utility model provides a kind of anti-riot coded lock that is made of password and mechanical interlocking principle, and having only principle with password and machinery to cooperatively interact could locking and unblank, thereby effectively stops to steal lock, security insurance.

Solution of the present utility model is: anti-riot coded lock constitutes by being installed in Cipher mechanism in the coded lock case and the mechanical locking mechanical interlocking of unblanking.The coded lock case is provided with the cipher wheel hole, password encryption wheel hole, lockpin hole, escape axis hole, the axis hole of unblanking, locking axis hole, latch hole; Cipher mechanism comprises: bolt, cipher wheel, password encryption wheel, password gear wheel, gear wheel chute, locating slot, gear wheel draw-in groove, gear wheel card, escape axle, escape axle sheet, return spring; The mechanical locking unlocking mechanism comprises lock pin, locking plate, safety plug, locking plate convex clip, the axle of unblanking, unblank an axle card, the bolt of unblanking, locking axle, locking axle card, locking bolt, lock bolt, compression spring, escape key, the key of unblanking.

The utility model adopts the principle locking of password and mechanical interlocking and unblanks.In Cipher mechanism, cipher wheel and password encryption wheel are garden nail shape, the garden plate wheel of cipher wheel is provided with the 0-9 password figure, with the hexagon keyhole, cipher wheel and password encryption wheel are contained in respectively in cipher wheel hole and the password encryption wheel hole, password encryption wheel hole wall upper edge orifice ring shape is provided with 01 to 24 password encryption number, on cipher wheel and the password encryption wheel shaft password gear wheel is housed respectively, gear wheel card and compression spring, the password gear wheel is provided with the gear wheel chute, locating slot, the gear wheel draw-in groove, the effect that gear wheel is stuck in spring embeds in any gear wheel draw-in groove down, cipher wheel and password encryption wheel are promptly by locking, and rotate with the password gear wheel, have only and the unlatching key is inserted the escape axle turn clockwise and drive the displacement of password bolt, alignd when consistent in password bolt and the escape hole on the clamping plate, with the escape key cipher wheel is depressed again, the password wheel shaft is inserted in the escape hole, when the gear wheel card breaks away from the gear wheel draw-in groove, ability rotational password wheel and password encryption wheel are provided with password, when taking away the escape key and opening key.Set password is by locking, in mechanical locking and the unlocking mechanism, during mechanical locking, at first lock bolt is inserted in the latch hole, again lock pin is pressed in the lock case, lock pin is inserted in the lockpin hole that the latch hole internal lock latches, because lock pin and locking plate are the lock pin assembly of welding one, driving locking plate when lock pin presses down glides, thereby make locking plate convex clip on the locking plate by the bottom table top that slides into down the password gear wheel in the gear wheel chute, safety plug also inserts locking password bolt in the insurance pin-and-hole on the password bolt simultaneously, collision locking bolt made the locking stud shaft to the slip self-locking, at this moment when lock pin pressed down simultaneously, password and mechanical interlocking locking, rotational password wheel and password encryption wheel are with secret locking password then.

The utility model has been owing to adopted the principle of password and mechanical interlocking, has advantages such as reasonable in design, easy to manufacture, the convenience of encoding, flexible operation, the scope of application are wide, safe and reliable, burglary insurance.
