Description

Lock for safe deposit box

The utility model relates to a kind of lockset, especially for the lockset on the safe deposit box.

An existing at present lock has the only lock for safe deposit box of lock effect to another lockset.But its structure has nothing in common with each other.As the 9th volume on the 30th phase utility model patent communique disclosed a kind of＜conbined public or double key dual fail-safe door lock (application number 92239139.4) its primary structure is that it has two lock bodies, fixes two lock cylinders respectively, one of them lock cylinder control gear tooth bar, another controls pawl, carries out the dual fail-safe locking.Its weak point is some complexity of structure, and lock a door the operation one definite sequence will be arranged, use more loaded down with trivial details.

The purpose of this utility model be to provide a kind of simple in structure, use all lock for safe deposit box easily of both sides.

The purpose of this utility model can realize by following measure: a kind of lock for safe deposit box, its two cross flute profile ball lock heads are fixed on the back shroud, the lock core end that wherein main tapered end passes back shroud is fixed with dead bolt and dials plate, the driving lever of this crank and rocker mechanism is corresponding with the dial hole on the bolt plate, on bolt plate, also be provided with the guiding cylindrical void, the axis of guide on itself and the lock housing is complementary, the set dead bolt of this bolt plate one end is corresponding with the through hole of lock housing sidewall, it is characterized in that: the lock core end that secondary tapered end passes back shroud is fixed with the lobe plate of rotary stopper mechanism, its driven member is that an end is located at the lockplate on the lockplate axle, perpendicular on the locking notch of its other end and the bolt plate and to be positioned at the slide block of back shroud chute corresponding, on back shroud, also establish another minor axis, torsionspring one end on it is located on the back shroud, and the other end is located at the lockplate front end and is higher than on the projection on its plane.The one side vertical fixing opposite with slide block has an end of bolt plate dial axis on bolt plate, and it is corresponding with the flap slit opening, and this is located at the end that the flap on the axis of guide in the lock housing is fixed with torsionspring, and the other end of this spring is fixed on the lock housing.Outside at cross flute profile cylinder lock is provided with protecting crust, also has anti-drilling board in the shell.

The utility model mainly includes lock head component and lock body assembly.Lock head component includes major and minor tapered end again and dials plate and lobe plate with their corresponding dead bolts.The lock body assembly mainly includes: back shroud, lockplate, dead bolt, bolt plate, flap, the axis of guide, lock housing and torsionspring.Wherein major-minor tapered end (promptly itself locking and the jack per line lock) is cross flute profile cylinder lock.These two tapered ends are separately fixed on the back shroud, and pass on the lock core end side face of back shroud and be fixed with respectively and can dial plate and lobe plate with the dead bolt that lock core rotates synchronously.The lobe plate that is fixed on the secondary tapered end is a disc cam, is provided with the through hole that is complementary with the lock core side face in its center of rotation.The driven member that is complementary with this lobe plate is a lockplate, and it is located on the back shroud.This back shroud that places on the lock housing inner convex platform is a flat board, its one side middle part outwardly is fixed with two tapered ends, one side vertical fixing inwardly has the lockplate axle, one end is located at the oscillating motion the done lockplate on this, it is corresponding with the slide block on the bolt plate of passing chute in order to lock notch for the slit opening of its stripe board other end, when making the bolt plate slide block be positioned at back shroud chute anteposition lockplate with chute after the position block, so slide block can not after move, to realize the restrictive function of secondary tapered end to main tapered end.On back shroud, also establish another minor axis.Torsionspring one end that is located on this minor axis is located on the projection of back shroud, and the other end is located at the lockplate front end and is higher than on its dull and stereotyped projection.When with the key operated secondary tapered end of jack per line, along with the also rotation synchronously thereupon of rotating cam plate of lock core, so the cam work part makes it to leave chute with the lockplate extrapolation, the bolt plate shifting block moves not interrupted backward, has so just removed the effect of contraction of secondary tapered end to main tapered end.Lockplate is resetted.For the opening and closing that make lockplate reach appointed positions, be provided with rotary stopper mechanism on the lobe plate with on the corresponding position of cam nose contouring, the spacer pin of evagination with matching is located on the back shroud.

Being fixed on dead bolt on the main tapered end, to dial plate be that crank and rocker mechanism is that its center has the through hole that is complementary with the lock core side face, is provided with perpendicular driving lever on its plate face, and it is corresponding with the dial hole on the bolt plate.Plate shaped bolt plate one end has dead bolt by the securing member secured in parallel, also is provided with the guiding cylindrical void of level on this bolt plate except that being provided with dial hole, and it is complementary with the axis of guide that is located on the lock housing, makes bolt plate drive the dead bolt translation.Be provided with a slide block perpendicular and that can in the back shroud chute, move on the bolt plate in addition.For increasing the feel of switch master tapered end, the one side vertical fixing opposite with slide block has an end of bolt plate dial axis on bolt plate, and this minor axis is corresponding with the slit opening of flap.There is a through hole at plate shaped flap center, and it can be enclosed within on the interior axis of guide of lock housing and as the center and rotate, and other has a torsionspring one end to be fixed on the flap, and the other end is fixed on the lock housing.Lock housing is the cuboid housing of an opening, and the one sidewall is provided with the through hole that is complementary with dead bolt, and vertical fixing has an end of the axis of guide in lock housing.When using key operated main tapered end itself again after rotation jack per line key is opened secondary tapered end, along with the rotating lock tongue of lock core is dialled plate and also rotated synchronously thereupon, its driving lever that is positioned at the bolt plate dial hole to pusher, makes dead bolt enter lock housing, the unlatching of keeping chamber door bolt plate.This moment, the slide block on the bolt plate was in the back position of chute, and reverse rotation jack per line key is more at this moment closed (resetting) with secondary tapered end though administrative staff can take jack per line key lobe plate this moment away resets, because of slide block occupy-place lockplate can not block chute.But bolt plate reach when main tapered end is closed makes dead bolt enter lockhole first, in addition the slide block on it when being advanced to the chute anteposition under the effect of torsionspring lockplate just chute is blocked, it can realize the restrictive function to main tapered end again.
