Abstract
The utility model relates to a mechanical cipher lock, comprising a lock body, a lock core and a lock tongue. The utility model is characterized in that the inner end of the lock core is fixedly provided with an outer shifting fork whose both sides are provided with shifting blocks, the casing of the lock core at the outer side of the outer shifting fork is sheathed with two catch plates, the inner side of the shifting fork is provided with a gear and a gear rack which is engaged with the gear, and both sides of the gear are respectively provided with shifting blocks. The inner side of the lock body is provided with an inner shifting fork which can shift the shifting blocks on the gear, a fastener is jacked by a spring and is fastened in the inner shifting fork, the fastener can not be rotated optionally. And both sides of the lock tongue are respectively fixed with a limited block. The utility model has the advantages of high safety factor, simple structure and convenient operation.
Description
The utility model is a kind of lockset, particularly a kind of mechanical code lock.
The still standard machinery lock of installing on present most of security door, the safety factor of this lock is very low, and is very dangerous.General electronic password lock is not suitable for again using on the family security door, and the mechanical code lock that uses on the safety cabinet can not be used on the door too.
The purpose of this utility model provides a kind of coded lock of new mechanical formula, and it is fit to be used in family's door, and the characteristics of this lock are that safety factor is higher, and easy to use.
The purpose of this utility model is achieved in that it comprises lock body, lock core and dead bolt, the outer shift fork that it is characterized in that a two sides band shifting block of the inner fixed installation of lock core, be set with two dials on the lock core sleeve in the outer shift fork outside, the tooth bar that outer shift fork inboard is equipped with gear and is meshed with gear, the two sides of gear respectively has a shifting block, inboard at lock body, the interior shift fork of a shifting block on can handsetting gear is installed, a card is by spring jack-up, be stuck in the interior shift fork, it can not arbitrarily be rotated, and each fixes a limited block both sides of dead bolt.
Operating process of the present utility model is such: when unblanking, with key clockwise and rotate counterclockwise lock core, make outer shift fork come back rotation and stir two dials, make its direction that is unanimity (if direction is inconsistent, then, dead bolt can not be withdrawn, so lock can not be opened) because of the restriction of two limited blocks, at this moment, lock core is inwardly advanced, make outer shift fork can toggle it to gear, gear is rotated, can make the dead bolt withdrawal by rack drives, lock promptly leaves.Simultaneously, spring can make lock core reset.If indoor, then can at first press card with hand, make its break away from shift fork, at this moment in shift fork promptly can freely rotate, shift fork and the shifting block on the handsetting gear simultaneously in rotating promptly can transmitting gears, drive tooth bar and lock core make to lock to be opened.
The utility model combines rotating disc type coded lock and common pellet shot from a slingshot built-in lock, need not any auxiliary knob, only, can realize the combination of the double insurance of password and cylinder lock by the rotation of key.Increase indoor unlocking mechanism, promptly can be used in various security doors and common door.So it is simple in structure, easy to operate, external form and standard machinery built-in lock are as good as.Use master key, even use the key of this lock,, also have no way out if do not know password.The indoor unlocking mechanism of the utility model also is a cover double insurance mechanism in addition, if use indoor shift fork that gear is blocked, even know that outdoor password can not open door, so safety factor of the present utility model is than higher, for the people who loses key has accidentally removed future trouble, also make the solitary people that is in safer simultaneously.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the side structure sectional view of a kind of specific embodiment of the present utility model.
Fig. 2 is a fragmentary sectional elevation view of the present utility model.
Fig. 3 is a lateral plan of the present utility model.
1 is lock body among the figure, lock core 2,3rd is installed, dead bolt in the lock body.As seen from Figure 1, the inner and the dead bolt at dead bolt is installed with shift fork 4 outside, its two sides band shifting block, there is an overcoat 5 the lock core outside, it and lock body are one, put outward to be set with two dials 6,7, adorn a spring 8 in the outside of dial 7, its effect is that the position of two dials is inwardly kept, be a stop washer 9 between two dials, 10 is gears among the figure, and the two sides of gear all has shifting block, one side can be stirred by outer shift fork, and another side stretches out outside the lock body.In the both sides of gear one toothed rack 11 is arranged respectively, be fixedly linked with upper and lower dead bolt respectively.Be welded with two limited blocks 12 on upper lock tongue, they are positioned at the both sides of dial 6,7, limit their position.One end of spring 13 withstands on the inner of lock core, the other end withstands a card 14, card is in being stuck in the groove of shift fork 15 at ordinary times, when pressing card, shift fork 15 in promptly rotatable, its lower end has projection, can stretch out the outer shifting block of lock body by this protruding handsetting gear, realizes indoor unlatching and locking.
