Abstract

Disclosed is a safe locking device with an exchangeable cipher or a blind open system, which is composed of, a cipher drive plate, a locking bar, a positioning spring, and a door lock which is arranged in a safe door, wherein, through a rotating shaft, the cipher drive plate is connected with a cipher wheel, a locking sheet wheel, and a fixing sheathing wheel which are arranged in the safe door; a return spring is arranged between the cipher wheel and the locking sheet wheel. When the locking sheet wheel is pushed forwards, the locking sheet wheel can be disengaged form the fixing sheathing wheel; the locking sheet wheel is rotated, the cipher can be set again. The edge of the cipher wheel is provided with slot holes, and the slot hole for one digital is deepest. When the cipher wheel is rotated, the set cipher can be confirmed through feel counting, and the safe can be opened in a blind method.

Description

Safe locking device with exchangeable cipher or blind open system

But a kind of escape, the blind strong box locking device of opening relate to the manufacturing technology of strong box locking device.

The locking device of existing strongbox is made up of pin tumbler lock and number dial mostly.Because the structure of number dial, the number of number dial can not be set arbitrarily, changes; Number is exposed outside, and makes strongbox open under many people situation and gives away secrets easily, is not having under the occasion of illumination locking device blindly not open.

It is a kind of simple in structure that the utility model provides, and can change, set number arbitrarily, can have light to open after the match, closes and can blind easily opening safety case the strong box locking device that safety feature is high.

But a kind of escape, the blind strong box locking device of opening comprise lock, number dial, bolt, dead bolt, spring pin.On a strongbox, can establish some number dials simultaneously.The number dial is by turning cylinder, digit wheel, and back-moving spring, locking plate, location wheel, fixed pin shaft constitute.Some dead bolts were aimed at the opening groove that locking plate is taken turns in the number dial simultaneously when strongbox was opened, and rotation lock could be opened strongbox then.On locking plate wheel, have several vacations as groove, in case under the situation of damage insurance box structure not the pirate of the open strongbox.Each numeral at digit wheel is disposed grooved hole, wherein has the slotted eye at a numeral place the darkest, as the blind starting point of stirring counting of opening.Numeral on the digit wheel can be observed the number that whether has pushed setting by the amplifying lens that is located on the safe door.

Advantage of the present utility model is that the number of locking device can change setting arbitrarily, is provided with vacation as groove on the locking plate wheel, has improved the safety performance of locking device; Slotted eye is set on the digit wheel numeral determines the number of unlatching, make strongbox blindly to open, made things convenient for use.

Accompanying drawing is one of the utility model embodiment, and the utility model will be further described in conjunction with the accompanying drawings.

Fig. 1, the utility model schematic diagram;

Fig. 2, the utility model structural representation;

Fig. 3, number dial structural representation;

Fig. 4, locking plate wheel, the digit wheel schematic diagram.

The utility model is by lock 1, number dial 3, and bolt 5 is located hoodle 6 and constituted.Lock 1 rear portion is a gear 4, meshes together with tooth on the bolt 5, and bolt 5 is fixed on the safe door back by the screw activity.

Number dial 3 passes hole and digit wheel 9 on the safe door by turning cylinder 8, back-moving spring 10, and locking plate wheel 11, fixedly wheel 12 is fixed on the door.Wherein digit wheel 9 fixedly secures with turning cylinder 8 and links into an integrated entity, and fixedly wheel 12 is fixed on the rear portion of turning cylinder 8 by bearing pin 13.Back-moving spring 10 is inserted in turning cylinder 8, is located at digit wheel 9, between the locking plate wheel 11.Numeration system on the digit wheel 9 has hole slot 21 in the front of wheel at the digit wheel edge of aiming at numeral, and wherein the slotted eye of " 0 " digital number is the darkest, as the blind counting starting point of driving strongbox.Numeral on the digit wheel 9 can be observed by the lens 2 that are located on the door.Realize by the spring tip bolt 6 that is located at a back of the body location of digit wheel 9.Spring tip bolt 6 is by spring base 15, spring 16, and pin 17 constitutes, and having locating hole 19, false rubber groove 18, opening groove 20 on locking plate wheel 11.When strongbox need reset number, locking plate wheel 11 pushing forward, and turn to the position that will set numeral along turning cylinder 8, fixedly on the wheel 12, number just resets and finishes locating hole 19 by back-moving spring 10 embeddings on the back locking plate wheel 11 of loosing one's grip.

When the opening safety case, rotate number dial 3 earlier to the number of setting, rotation lock 1 then, and the gear driven bolt 5 on the lock 1 moves.In bolt 5 moving process, when the dead bolt 7 that connects together with bolt embedded in the number dial 3 in the opening groove 20 on the locking plate wheel 11, safe door was opened.Can not embed in the opening groove 20 if any a dead bolt, door just can't be opened.
