Abstract

The utility model relates to a code mechanism comprising a code disc with numbers, particularly a code varying alarm code lock provided with an alarm device and an on-off mechanism of a lock core shell. The utility model is characterized in that a code varying mechanism is arranged between the lock core shell and a number code disc; the code varying mechanism comprises an interlocking ring linked with the on-off mechanism. The interlocking ring is used for poking and rotating a positioning pin arranged on a rotating disc, and the positioning pin which is provided with a positioning hole and is under the action of an elastic element can insert into a code varying positioning ring of the positioning hole. The utility model causes a code lock to simply and conveniently change many different codes according to the desire of a user, and the safety of the lock is increased.

Description

Become sign indicating number alarm cipher lock

The utility model relates to a kind of coded lock.

" the multifunction cipher warning cylinder lock " of the ZL932266940 that has announced, include Cipher mechanism, comprise switching mechanism, warning device and the password lighting device etc. of lock core shell, it makes sled steal the person to be difficult for feel and sense of hearing coded lock being opened, and sled can be reported to the police when stealing; Can start lighting device when unblank night; As without password the time, can carry out self-locking from the indoor coded lock handle of stopping that utilizes, can open the lock with the key merely.But a lock has only a password, as need this lock is changed password, then need dismantle wherein quite a lot of parts and could change code number, and to be reassembled into lock also is trouble.Though to change password slightly convenient for coded lock on the conventional strongbox, need rotate combination disk repeatedly and remember a lot of code number, be inconvenient to locking the master.

But the utility model purpose provides a kind of change sign indicating number alarm cipher lock of simple and convenient conversion password number.

The utility model purpose is to realize like this, the Cipher mechanism that promptly keeps multifunction cipher warning cylinder lock, the structure such as switching mechanism, warning device, lighting device, self-locking handle that comprises lock core shell, between lock core shell and digital disk, set up and become the ink recorder structure, become the ink recorder structure and comprise interlocking ring with the switching mechanism interlock, by interlocking ring pull out commentaries on classics be installed in alignment pin on the rotating disk, be provided with locating hole and under the flexible member effect alignment pin can stretch into the mechanisms such as change sign indicating number centring ring of locating hole.During use, as long as digital disk is aimed at number, insert key, stir switching mechanism, alignment pin is stretched in the locating hole that becomes the sign indicating number centring ring, stir digital disk and make the number that number goes to needs change, password is promptly changed success.

By above-mentioned improvement, Cipher mechanism can immobilize, and one coded lock, can be willing to the many different passwords of simple and convenient ground replacing with the lock idea, has increased the safety of lock.

Give explanation below in conjunction with accompanying drawing

Fig. 1 is the structural representation after the utility model is plugged key (14).

Fig. 2 unloads P behind the key to view for Fig. 1.

Improved change sign indicating number alarm cipher lock on " multifunction cipher warning cylinder lock " basis, have equally band digital disk (1) Cipher mechanism, comprise mechanisms such as lock core shell (3) switching mechanism, warning device, the lighting device that contains two small electric bulbs (11) and self-locking handle.Different is to be provided with to become the ink recorder structure between lock core shell and code-locked dish, become the interlocking ring (8) that individual breach is arranged on its that links with switching mechanism is arranged in the ink recorder structure, after the key (14) of band " ten " prefix inserts lock core, digital disk is gone to the password of setting, turn the promptly rotatable interlocking ring of key, pull out the alignment pin (9) that commentaries on classics is installed in rotating disk (12) by the breach on it, a change sign indicating number centring ring (7) that is provided with locating hole (13) is arranged, when password on time, alignment pin under flexible member (4) effect necessarily stretches in the locating hole (13), coded lock is opened, if the location lock can not enter locating hole, the alignment pin end withstands on the digital disk inner surface, and by the warning device that is connected with power supply (6) that shell (5) contains chimes of doom promptly takes place this moment.After opening as door, key returns the home position, and alignment pin is the retraction original position under the flexible member effect.

When the need Change Password, only need alignment pin to be in the position of inserting locating hole, rotation can become the digital disk that yard centring ring circumferentially slides relatively, and lock is main can any Change Password.Be provided with a plurality of spring ball mechanisms (15) that contact with the digital disk inner surface owing to become the sign indicating number centring ring, in wherein ball is pressed on and cheats on the digital disk inner surface, when so the centring ring pin is not inserted in the locating hole, the rotation digital disk can drive a change sign indicating number centring ring and rotate synchronously, guarantees that the password of having aimed at can not be shifted.In order to allow digital disk center on rotational, so the flange of digital disk rear end and lock core shell all is fixed on the dish seat (2), the holding tray seat is concentric with axis.Steal the person with drilling tool brill lock, so the interlocking ring end is provided with anti-drilling sheet (10) in order to prevent sled.

Claims

1. one kind includes the Cipher mechanism of being with digital disk (1), comprise switching mechanism, the warning device of lock core shell (3), the change sign indicating number alarm cipher lock of lighting device, it is characterized in that between lock core shell and digital disk, being provided with and become the ink recorder structure, become the ink recorder structure comprise with the interlocking ring (8) of switching mechanism interlock, by interlocking ring dial commentaries on classics the alignment pin that is installed in rotating disk (12) (9), be provided with locating hole (13) and under flexible member (4) effect alignment pin can stretch into the change sign indicating number centring ring (7) of locating hole.

2. by the described change sign indicating number of claim 1 alarm cipher lock, it is characterized in that becoming yard centring ring and be provided with the spring ball mechanism (15) that contacts with the digital disk inner surface.

3. by the described change sign indicating number of claim 1 alarm cipher lock, it is characterized in that the flange end of digital disk rear end and lock core shell all is fixed on the dish seat (2).
