Description

Compound lock

The utility model relates to the composite lock of using in a kind of daily life.

Not outgoing call of the lock coded lock of using in the daily life of Chu Shouing and with key operated common lock in the market, the shortcoming of coded lock is easily to forget the rotary dialing wheel, the key of common lock is easily lost or stolen person gets the key sample.

The purpose of this utility model is to avoid coded lock and common lock weak point and provides coded lock and common lock is the composite lock of one.

The purpose of this utility model realizes by following design scheme, in composite lock lock body (1), depart from center dress common lock lock core (2) and cipher lock core (3), coded lock locking bar (4) left end pin is blocked up (5), right-hand member fixed limit pin (6), a helicla flute (9) that is complementary with spacer pin (6) is processed in one of composite lock lock body left end processing and the stifled groove (7) that is complementary of lock on the sidewall of shock mount hole (8).

Advantage of the present utility model: because the coded lock locking bar stretches out outside the pin when not locking, the user can never forget the lock cipher lock, because coded lock pins the common lock keyhole, has solved key loss and sampled cause dangerous.

Below in conjunction with accompanying drawing embodiment of the present utility model is described: in composite lock lock body (1), depart from center dress common lock lock core (2) and cipher lock core (3), dialing wheel (10) is radially installed, coded lock locking bar (4) left end pin is blocked up (5), right-hand member fixed limit pin (6).One of composite lock lock body left end processing is blocked up the groove (7) that is complementary with lock, when coded lock locks, lock is stifled to be entered in the groove, helicla flute (9) that is complementary with spacer pin (6) of processing on the sidewall of shock mount hole (8), when locking bar passed in and out, spacer pin moved along helicla flute, and locking bar is motion vertically on the one hand, rotate on the other hand, during lock, the locking bar counterclockwise rotation, lock is stifled to be entered in the groove (7), block common lock core port, when opening coded lock, locking bar is under the spring tension effect, and locking bar moves to left and changes clockwise, lock is stifled to leave the normal key mouth, and the user opens common lock with key.

Second embodiment of the utility model is that coded lock dialing wheel (10) is axially to install.

Claims (1)

1, a kind of composite lock, it is characterized in that departing from the composite lock lock body (1) center dress common lock lock core (2) and cipher lock core (3), coded lock locking bar (4) left end pin is blocked up (5), right-hand member fixed limit pin (6), a helicla flute (9) that is complementary with spacer pin (6) is processed in one of composite lock lock body right-hand member processing and the stifled groove (7) that is complementary of lock on the sidewall of shock mount hole (8).
