Abstract

The utility model relates to a coded lock used on a safe box, a lock core structure consisting of a lock plate (or a marble) and a spring is arranged in the middle of a lock shaft of a number lock, and a lock core sleeve structure consisting of a lock plate (or a marble) slot hole is arranged on the corresponding position of a number disc hole corresponding to the lock core structure, so that the lock core structure and the lock core sleeve structure form a lock body. The utility model discloses close lock body and password driver plate as an organic whole, its dependable performance, it is convenient to open, and the structure is more simple, reduce cost, in addition the utility model discloses still have alarming function, the theftproof effect is showing.

Description

Cipher lock for safe

The utility model relates to a kind of lock, used coded lock on particularly a kind of safety cabinet case.

At present, lock body on the safety cabinet case and password dial are two and independently divide three-dimensionally separately that open cumbersomely, and cryptography architecture is also simpler, just relies on the password dial to control, and does not have warning function.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of that lock body and password dial is integrated and have a safety cabinet case coded lock of warning function.

Technical solution of the present utility model:

A kind of safety cabinet case coded lock, it includes number tapered end 1, figure disc 2 and three spacers 3, its in the outer part two spacers 3 and figure disc 2 movable sets on the tapered end axle of number tapered end 1, inboard 3 of spacers are fixedly mounted on the tapered end axle head of number tapered end 1, it is characterized in that in the tapered end axle middle part of number tapered end 1, being provided with the lock core structure of forming by locking plate (or pellet shot from a slingshot) 4 and spring 5, to should on the relevant position of figure disc 2 endoporus, being provided with the lock core nested structure that constitutes by locking plate (or pellet shot from a slingshot) slotted eye 6 by lock core structure, make them constitute a lock body.

The utility model is integrated lock body and password dial, its dependable performance, and it is convenient to open, and structure is more simple, can reduce cost, and the utility model also has warning function in addition, and anti-theft effect is better.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a figure disc schematic diagram of the present utility model;

Fig. 3 is the connection diagram of the utility model and normally closed interlock;

Fig. 4 is an A--A direction profile among Fig. 3.

As Fig. 1,2, when the utility model uses, insert in the number tapered end 1 with private key earlier, locking plate (or pellet shot from a slingshot) 4 of lock core in its tapered end axle entered under the effect of spring 5 in each self-corresponding locking plate (or pellet shot from a slingshot) slotted eye 6 of figure disc 2 endoporus, make the alignment of lock core structure and lock core nested structure, just rotatable number tapered end 1 drove spacer 3 according to the password of figure disc 2 by number tapered end 1 and rotated this moment, opened the safety cabinet case at last.When lock core structure and lock core nested structure did not align, number tapered end 1 and locate 3 and can't stir promptly can't be opened the safety cabinet case.

The utility model also has anti-theft alarm function simultaneously, as Fig. 3,4, on three spacers 3 correspondence separately groove in its opposite side outer rim one plush copper 7 is outwards arranged, correspondence is provided with three normally closed interlocks 8 below the outer rim of three spacers 3, a reed in three normally closed interlocks 8 keeps certain interval respectively and between the exterior rim of spacer separately 3, another reed of three normally closed interlocks 8 connects and is connected in series with normally open contact on the safety cabinet case handgrip inner edge by lead, and last is with being attempted by on the alarm.After key inserts, when rotating number tapered end 1 to needed password, then the groove of spacer 3 is aimed at one by one, but the safety cabinet case is in opening, the plush copper 7 of opposite side is opened each self-corresponding normally closed interlock 8 one by one on each spacer 3 at this moment, when the handgrip of pulling the safety cabinet case is like this opened the safety cabinet case, because normally closed interlock 8 is in open position, so the normally open contact closure on the handgrip inner edge can not reported to the police yet.When if a slice does not align the enable possition arbitrarily in three spacers 3 of the present utility model, promptly there is one not to be opened in three normally closed interlocks 8, pull safety cabinet case handgrip this moment, then the interior mechanism of handgrip oppresses the normally open contact closure on its limit, so make the safety cabinet case send alarm sound, play antitheft effect.

Claims

1, a kind of safety cabinet case coded lock, it includes number tapered end 1, figure disc 2 and three spacers 3, its in the outer part two spacers 3 and figure disc 2 movable sets on the tapered end axle of number tapered end 1, inboard 3 of spacers are fixedly mounted on the tapered end axle head of number tapered end 1, it is characterized in that in the tapered end axle middle part of number tapered end 1, being provided with the lock core structure of forming by locking plate (or pellet shot from a slingshot) 4 and spring 5, to should on the relevant position of figure disc 2 endoporus, being provided with the lock core nested structure that constitutes by locking plate (or pellet shot from a slingshot) slotted eye 6 by lock core structure, make them constitute a lock body.

2, by the described safety cabinet case of claim 1 coded lock, it is characterized in that on three spacers 3 correspondence separately groove in its opposite side outer rim one plush copper 7 is outwards arranged, correspondence is provided with three normally closed interlocks 8 below the outer rim of three spacers 3, a reed in three normally closed interlocks 8 respectively and separately keeps certain interval between the exterior rim of spacer 3, another reed of three normally closed interlocks 8 connects and is connected in series with normally open contact on the safety cabinet case handgrip inner edge by lead, and last is with being attempted by on the alarm.
