Description

Technical Field

[0002] Existing electronic locks are generally fingerprint locks or password locks. The lock is triggered by fingerprint or password input on the panel, and the motor inside the lock body drives the lock tongue to retract to unlock.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0024] Depend on Figure 1 Combination Figure 2-7As shown, an electronic emergency lock cylinder comprises a lock cylinder shell 1, a shift block 2 and an operating member 3, wherein the shift block 2 is arranged on the lock cylinder shell 1, and a mechanical operating mechanism 4, an electric operating mechanism 5 and a clutch mechanism 6 are arranged in the lock cylinder shell 1, wherein the clutch mechanism 6 comprises a connecting member 61 and a positioning member 62, wherein the positioning member 62 cooperates with the shift block 2 in axial sliding and circumferential rotation, wherein the operating member 3 is connected to the shift block 2 via the connecting member 61, and wherein the clutch mechanism 6 has a first position in which the connecting member 61 is separated from the positioning member 62, a second position in which the connecting member 61 is driven by the mechanical operating mechanism 4 to move and engage with the positioning member 62 to drive the shift block 2 to move, and a third position in which the positioning member 62 is driven by the electric operating mechanism 5 to move and engage with the connecting member 61 to drive the shift block 2 to move. The beneficial effect of the present invention is that a mechanical operating mechanism and an electric operating mechanism are provided, and both the mechanical operating mechanism and the electric operating mechanism can be connected with the shift block to realize unlocking by the shift block action, so as to avoid that the lock cylinder can only be unlocked after one method fails and violent damage is required. The setting of the clutch mechanism avoids the mutual influence of the mechanical operating mechanism and the electric operating mechanism when they act, and can reliably drive the shift block to act, so that the product can act reliably. The present invention also has the advantages of simple structure, convenient assembly, reliable action, long service life, etc.

[0025] The operating member 3 is connected to the connecting member 61 through the transmission member 31, and the connecting member 61 cooperates with the transmission member 31 in axial sliding and circumferential rotation. Specifically, the operating member and the transmission member can realize circumferential rotation linkage through the means of grooves and protrusions. Generally speaking, the operating member can be connected to the handle or can be a part of the handle. The transmission member and the connecting member can cooperate with each other in the form of protrusions and slots, that is, the connecting member can move axially along the edge of the protrusion, and when rotating, the synchronous rotation is realized through the cooperation of the protrusion and the slot, so that the operating member can reliably drive the connecting member to rotate through the transmission member, and the connecting member can be disengaged from the positioning member at the same time.

[0026] The mechanical operating mechanism 4 includes a mechanical lock core 41 and a push rod 42. The push rod 42 has a first position in which the push rod 42 extends and pushes the connecting member 61 so that the connecting member 61 is combined with the positioning member 62, and a second position in which the push rod 42 is retracted. Specifically, the mechanical operating mechanism 4 includes a mechanical lock core 41 including a keyhole 411 for inserting a key 8. The mechanical lock core 41 drives the push rod 42 to extend and retract by circumferential rotation. When the mechanical key is inserted into the keyhole, the push rod is pushed out by rotation, driving the connecting member to push out the positioning block, and the connecting groove and the positioning block cooperate. At this time, the rotating operating member (handle) can drive the shift block to move and unlock. Of course, the mechanical operating mechanism can also use a password lock or other methods to push the push rod out. Specifically, a latch is provided on the push rod, and an arc hole is provided on the mechanical lock core. The latch is provided in the arc hole. When the mechanical lock core rotates, the push rod is driven to be pushed out or retracted by the latch. The arc hole can be self-locking, avoiding direct pushing of the mechanical lock core or the push rod, thereby improving the safety performance of the product.

[0027] The electric operating mechanism 5 includes a power source 51, an electric transmission assembly 52 and a movable block 53. The power source 51 is connected to the movable block 53 through the electric transmission assembly 52. ​​The movable block 53 abuts against the positioning member 62 and is used to drive the positioning member 62 to move axially and engage with the connecting member 61. Specifically, the electric transmission assembly 52 includes a transmission shaft 521, a transmission elastic member 522 and a transmission pin 523 used to drive the transmission elastic member 522 to move axially. The transmission elastic member 522 is sleeved outside the transmission shaft 521 and abuts against the movable block 53. The transmission pin 523 is arranged on the transmission shaft 521 and is linked to the transmission shaft 521. The transmission elastic member is driven by the transmission pin to drive the movable block to move. The movable block is driven by the transmission elastic member, which has a certain elasticity, avoids the rigid connection from damaging the electric operating mechanism, and prolongs the service life of the product. Specifically, the power source 51 is connected to the transmission shaft 521 through the gear set 524 and drives the transmission pin 523 to rotate circumferentially through the transmission shaft 521. The transmission pin 523 is inserted into the pitch of the transmission elastic member 522 and drives the transmission elastic member 522 to move axially along the transmission shaft 521. Of course, in the actual production process, sprocket drive, belt drive and other methods can also be used. The present invention drives the rotation of the transmission pin through the rotation of the transmission shaft, and the transmission pin is inserted into the pitch of the transmission elastic member (spring), that is, after rotation, the pitch of the spring will change, thereby driving the movable block to move, and the transmission is reliable. Long service life.

[0028] The lock core housing 1 is provided with a fixing block 7, and the fixing block 7 is provided with a first elastic member 71. The first elastic member 71 abuts against the positioning member 62 and has a movement tendency to drive the positioning member 62 away from the connecting member 61 so that the clutch mechanism 6 is in the first position. Such a structure allows the positioning member to move smoothly. Usually, the positioning member is usually T-shaped, that is, the positioning block can be a straight line shape. Of course, in the actual production process, a cross shape or a cross shape can be set as needed.

[0029] The connecting member 61 is provided with a connecting groove 611 or a positioning block 621, and the positioning member 62 is provided with a positioning block 621 or a connecting groove 611. The positioning member 62 passes through the shifting block 2 and the fixing block 7, and the positioning member 62 and the shifting block 2, and the positioning member 62 and the fixing block 7 are axially slidable and circumferentially rotated. The positioning block 621 and the connecting groove 611 cooperate with each other when the clutch mechanism is in the second position and the third position, so that the positioning member 62 and the connecting member 61 are linked. Specifically, the lock core housing 1 is provided with a first limiting plate 11, a first limiting block 12 and a first limiting elastic member 13. The first limiting plate 11 is inserted into the transmission member for axial limiting of the transmission member 31. The connecting member 61 is provided with a receiving groove 612 for accommodating the first limiting block 12. The first limiting elastic member 13 abuts against the first limiting block 12 and has a movement tendency to drive the first limiting block 12 to move toward the outer surface of the connecting member 61. The connecting piece and the positioning piece can be engaged or separated, so that when the handle is actuated, the positioning piece can be rotated, thereby causing the shift block to move, and unlocking is convenient and reliable.
