Abstract

The utility model discloses a synchronous cylinder lock, comprising two or more than two cylinder lock cores and lifting gears (stems); the lifting gears which are coaxially fixedly connected with each cylinder lock core are connected with each other via being engaged with intermediate gears (or via being connected with a connecting rod). The synchronous cylinder lock can be unlocked via two or more than two keys being inserted into the cylinder lock cores all together. (as shown in the figure 2).

Description

Synchronous cylinder lock

As the saying goes and open different locks with different keys.Yet such situation is arranged: lose key, lock usually can be with one in some keys that pool opening.So in order to prevent that lock from being staggered or opened steathily by the burglar, twin-lock has all been installed by a lot of families on door, safety cabinet then adopts cylinder lock and combination lock simultaneously, improves the security insurance degree with this.

The synchronous cylinder lock of the utility model has increased transmission mechanism on the basis of traditional cylinder lock, a plurality of pellet shot from a slingshot cores are connected together, make a plurality of pellet shot from a slingshot core mutual restriction, interlocked with one another, rotation synchronously, have only and the correct key of coupling is all inserted core many, lock could be opened (only rotating any in many keys), lack key, or there is a key not right, lock just can not be opened, thereby has broken the routine of " opening different locks with different keys ".

If a kind of lock has n kind key coupling, so: one is traditional cylinder lock 1/n by the possibility that any key is opened once, and two traditional cylinder locks are 1/2n by the possibility that any two keys are all opened once; But one then is the synchronous cylinder lock of the two pellet shot from a slingshot cores of conbined public or double key 1/n by the possibility that any two keys are opened once ², and one only be the synchronous cylinder lock of three keys, three pellet shot from a slingshot cores 1/n by the possibility that any three keys are opened once ³This shows that cylinder lock has greatly improved the security insurance degree synchronously.The burglar wants to drive synchronous cylinder lock steathily, can be described as impossible.

The synchronous cylinder lock of the utility model can be used for door and windows such as esidential building, unit orderly room, storehouse, and classified papers cabinet, file cabinet, safety cabinet etc.

Now specify by embodiment:

Embodiment 1: the synchronous pin tumbler lock of the two pellet shot from a slingshot cores of conbined public or double key.

Present embodiment is on the basis of the dual fail-safe 502 type pin tumbler lockes that BJ Construction Lock Factory produces, changed the design of cover plate and lock body shell, increased travelling gear, thereby realized the mutual restriction of two tapered end pellet shot from a slingshot cores, interlocked with one another, rotation synchronously.

Fig. 1 is the tapered end assembly, and (1) is the pellet shot from a slingshot core, and (2) are connecting rod.The correct key of coupling is inserted the pellet shot from a slingshot core just can make the rotation of pellet shot from a slingshot core, and drive the connecting rod rotation.

Fig. 2 is the cover plate assembly, (3) be cover plate, shifting block gear (5) with axis hole rivet (4) riveting on the cover board, (4) and (5) can on cover plate (3), make coaxial rotation, mesomerism gear (6) is assemblied on the cover plate (3) with axle rivet (7), and shifting block gear (5) and mesomerism gear (6) are meshing with each other.

Fig. 3 is lock body assembly, and (8) are dead bolt, and (9) are handle, and (10) are lock body shell.The remainder of lock body assembly is identical with dual fail-safe 502 type pin tumbler lockes, and using method is also identical, only all is two covers (only adorn a cover also can).

Present embodiment is equipped with two tapered ends, have only the correct two pellet shot from a slingshot cores that insert of two keys outdoor, lock could be opened or locked, its process is: rotate any in two keys, at this moment a pellet shot from a slingshot core (1), the connecting rod that is attached thereto (2), make coaxial rotation together by the axis hole rivet (4) of connecting rod (2) drive and coaxial shifting block gear (5), and shifting block gear (5) drives another group shifting block gear (5) by the gears engaged relation through mesomerism gear (6), axis hole rivet (4), connecting rod (2), pellet shot from a slingshot core (1) rotates synchronously until another key, meanwhile, the mechanism that the shifting block gear is stirred in the lock body assembly ensconces in the lock housing dead bolt, and dead bolt can not eject, but the door free switch, or dead bolt is ejected, dead bolt and handle be all by lock jail, lacks key or key is incorrect, and indoor and outdoor all can not be opened by lock.

Embodiment 2: the synchronous spring padlock of the two pellet shot from a slingshot cores of conbined public or double key.

Present embodiment makes two pellet shot from a slingshot core mutual restriction with the connecting rod transmission on the basis of traditional padlocks, interlocked with one another, synchronously rotation.Fig. 4 is the drive mechanism figure of the two pellet shot from a slingshot cores of conbined public or double key, pellet shot from a slingshot core (11) and affixed being integral of turning handle (12), can only make coaxial rotation, connecting rod (13) is connected with turning handle (12) with axle (14), and angle α is 1/2 of a pellet shot from a slingshot core hard-over.

Present embodiment is compared with traditional padlocks, only many pellet shot from a slingshot cores and a cover connecting rod transmission mechanism, and except that the corresponding increase of lock housing, remainder is identical with traditional padlocks.Be that this synchronous cylinder lock must could be opened with two correct keys insertion pellet shot from a slingshot cores of coupling, otherwise just lock can not be opened.

Claims

1. a synchronous cylinder lock is characterized in that it has two or more pellet shot from a slingshot cores that couple together with transmission mechanism.

2. synchronous cylinder lock according to claim 1 is characterized in that the shifting block gear of its transmission mechanism and pellet shot from a slingshot core are coaxial affixed, interconnects by the engagement with mesomerism gear.

3. synchronous cylinder lock according to claim 1 is characterized in that the turning handle of its transmission mechanism and pellet shot from a slingshot core are affixed, by interconnecting with being connected of connecting rod.
