Description

A kind of duplex secure mechanical lock

Technical field

The utility model relates to a kind of mechanical lock, particularly a kind of duplex secure mechanical lock.

Background technology

The common mechanical lockset all has lockhole, and under the prerequisite of not using key, technology unlocking is easy to, and only needs to use the various instruments that can enter lockhole, adjusts the length of pellet shot from a slingshot, just can unblank.If user's key loss again can't technology unlocking, just can only force open the door by force.

Summary of the invention

The purpose of this utility model provides a kind of technology unlocking that both prevented, the duplex secure mechanical that can unblank under the key loss situation again lock.

The utility model is realized according to following technical proposals:

A kind of duplex secure mechanical lock, it is made of two covers lock control devices in parallel, and a cover is the available key operated cylinder lock that has the lock core bluff piece, and another set of is mechanical code lock, claims unlocking device again, and both can control moving of bolt respectively; The main part of above-mentioned cylinder lock is the common spring lock construction, outside first pellet shot from a slingshot, between rotor lock core and stator lock body, add the lock core bluff piece, its two ends are limited in the rotor lock core outer rim, one end is curved, the removable groove that is positioned at the stator lock body that enters of the other end, spring and slide block are arranged in the groove, the unblank bottom of key is narrower, structure and common spring latching segment coupling, and it is upper wider, have the hole, the size in this hole equates with the cross section physical dimension of lock core bluff piece or is smaller that the bottom of key is the inclined-plane, and the rotor lock core drives the bolt shift fork;

Above-mentioned mechanical code lock comprises bat-handle switch and check mark knob, connects a rotary drum in the check mark knob, and rotary drum has equally distributed number hole near knob one side periphery, and opposite side has the comparison groove; Switch through axle in the bat-handle switch, near handle one side oval cam is housed in the rotating shaft, opposite side has the shift fork that is acute angle with major axis of cam; Rotary drum number hole position and cam top are provided with a rectangular clamp, and it has bayonet lock movable up and down corresponding to porose on the number hole position in hole, and rectangular clamp one end has support bar and back-moving spring; Rotary drum comparison groove position and shift fork top are provided with the comparison litter, and the corresponding rotary drum comparison of litter groove has the hole on the position, and bayonet lock movable up and down is arranged in the hole, and there are plate nail, another termination bolt pull bar of litter in the position of its corresponding shift fork.

The utility model only allows that private key enters lockhole and unblanks, various tool will enter lockhole, must at first mobile lock core bluff piece, the lock core bluff piece only slightly moves, just can lock core is stuck, can't rotate,, but not have the function of lockhole though the utility model has lockhole, be equivalent to " imperforation lock ", in case do not have private key, adopt any instrument all can't unblank, therefore, the utility model also is provided with a unlock password device, can unblank by password, prevent key loss after, can't unblank.

The specific embodiment

As shown in Figure 1, the utility model is made of two covers lock control devices in parallel, one cover is the available key operated cylinder lock that has the lock core bluff piece (2), the shift fork (2-1) that lock core rotor (2-3) and lockhole (2-2) is arranged on it and be used to drive bolt (3); Another set of is mechanical code lock (1), claims unlocking device again, comprises four groups of check mark knobs (1-1), bat-handle switch (1-3) and bolt pull bar (1-2), and two covering devices can be controlled moving of bolt (3) respectively;

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the main part of cylinder lock is common spring lock construction (2-7), internal construction can be the structure (omitting in the drawings) of any cylinder lock, outside first pellet shot from a slingshot, add lock core bluff piece (2-4) between rotor lock core (2-3) and the stator lock body (2-6), its two ends are limited in the rotor lock core outer rim, one end is curved, the removable groove that is positioned at the stator lock body that enters of the other end, spring and slide block (2-5) are arranged in the groove, the unblank bottom (2-12) of key (2-10) is narrower, structure and common spring latching segment coupling, its top (2-11) broad, have hole (2-13), the size in this hole equates with the cross section physical dimension of lock core bluff piece (2-4) or is smaller that the bottom of key is inclined-plane (2-8), key on through wires hole (2-9) is arranged, rotor lock core (2-3) drives bolt shift fork (2-1); Because the key bottom is the inclined-plane, can insert lockhole (2-2), after insertion put in place, the lock core bluff piece can pass hole (2-13) on the key just and reset under spring action, and key is unblanked with regard to rotatable lock core rotor.

As Fig. 6, Fig. 7, shown in Figure 8, mechanical code lock comprises bat-handle switch (1-3) and check mark knob (1-1), connect a rotary drum (1-12) in the check mark knob, rotary drum has equally distributed number hole (1-15) near knob one side periphery, be 8 holes in this example, opposite side has comparison groove (1-4); Switch through axle (1-9) in the bat-handle switch, near handle one side oval cam (1-13) is housed in the rotating shaft, opposite side has the shift fork (1-6) that is miter angle with major axis of cam; Rotary drum number hole position and cam top are provided with a rectangular clamp (1-11), and it has bayonet lock movable up and down (1-5) corresponding to porose on the number hole position in hole, and rectangular clamp one end has support bar (1-18) and back-moving spring (1-17); Rotary drum comparison groove position and shift fork top are provided with comparison litter (1-10), the corresponding rotary drum comparison of litter groove has the hole on the position, bayonet lock movable up and down (1-7) is arranged in the hole, and there are plate nail (1-8), another termination bolt pull bar (1-2) of litter in the position of its corresponding shift fork (1-6).Its work principle is: because the bayonet lock (1-7) on the litter has only the position of aiming at rotary drum comparison groove (1-4) to move right by rotary drum, comparison groove on the rotary drum has only one, its corresponding unique rotary drum number hole (1-15), only under the correct situation of number, pull bat-handle switch, bayonet lock (1-5) falls into number hole (1-15), continue to pull bat-handle switch, bayonet lock (1-7) can be smoothly by comparison groove (1-4), by shift fork (1-6) swinging plate nail (1-8), move right thereby drive litter (1-10), unblank.
