With continued reference to fig. 2 and 3, in some embodiments, the lock 100 may further include a reset element 51 and a locking device.
The reset member 51 is used for continuously providing the second latch bolt assembly 22 with a reset force extending out of the second lock hole 123, i.e., the reset member 51 continuously provides the second latch bolt assembly 22 with a reset force in a direction from the second position 222 to the first position 221. When the first transmission element 411 receives external power and transmits the external power to the second latch bolt assembly 22, so that the second latch bolt assembly 22 is switched from the first position 221 to the second position 222, the acting force transmitted from the first transmission element 411 to the second latch bolt assembly 22 needs to overcome the reset force, and the purpose of switching the second latch bolt assembly 22 from the first position 221 to the second position 222 can be achieved.
The locking device is disposed in the accommodating cavity 13 and is used for locking the second latch bolt assembly 22 in the second position 222, that is, when the second latch bolt assembly 22 is switched from the first position 221 to the second position 222, the locking device locks the second latch bolt assembly 22 in the second position 222, so as to prevent the second latch bolt assembly 22 from rebounding from the second position 222 to the first position 221 under the action of the restoring force after the first transmission element 411 is restored.
In other embodiments, the position of the second latch bolt assembly 22 may be determined by the first transmission assembly 41.
Referring to fig. 1, fig. 2 and fig. 3, the first latch assembly 21 mainly includes a tongue body 211 and a connecting column 212, wherein the connecting column 212 is slidably disposed along an axial direction of the first latch hole 122 and is hinged to an end of the connecting column 212 close to the guide plate 12, and the tongue body 211 can selectively extend out of the first latch hole 122 or be accommodated in the accommodating cavity 13, that is, when the security door is in a closed state, the tongue body 211 extends out of the first latch hole 122 and extends into a latch groove disposed in the door frame and abuts against an inner wall of the latch groove; when the user performs the door opening action, the tongue body 211 can be accommodated in the accommodating cavity 13.
It should be noted that the present embodiment provides the tongue 211 capable of rotating around an axis parallel to the guide plate 12 and the bottom case 11, thereby realizing the bidirectional opening and closing of the door. Specifically, when the door is in a state of being closed but allowing the user to perform the door opening operation, that is, the tongue body 211 is in a state of extending out of the first lock hole 122 but being capable of retracting into the accommodating cavity 13, the tongue body 211 abuts against the side wall of the lock groove, at this time, when the user rotates the anti-theft door forward or reversely, the side wall of the lock groove exerts a force on the tongue body 211, so that the tongue body 211 is accommodated into the accommodating cavity 13, and the door opening operation is realized.
Referring to fig. 1, fig. 2 and fig. 3, the locking element 31 is disposed in the accommodating cavity 13, when the locking element 31 is located at the locking position, the locking element 31 contacts the tongue 211 and can limit the tongue 211 from rotating relative to the connecting column 212, when the locking element 31 is located at the unlocking position, the locking element 31 and the tongue 211 are separated from each other, and at this time, the tongue 211 can rotate relative to the connecting column 212 under the condition that the user performs a door opening operation.
Referring to fig. 4, in order to realize that the tongue body 211 can selectively rotate or be stationary relative to the connecting column 212, in one embodiment, the tongue body 211 can be provided with a limiting groove 2111, and the shape of the limiting groove 2111 can be a shape other than a circle, such as a triangle or a direction, and is not limited herein. Referring to fig. 2 and fig. 3 again, the locking assembly 31 may include a locking block 313, the locking block 313 may be slidably disposed on the bottom case 11, and the locking block 313 has an unlocking position and a locking position and can be switched between the unlocking position and the locking position. When the locking block 313 is located at the locking position, the locking block 313 is embedded into the limiting groove 2111, and the surface of the locking block 313 is attached to the side wall of the limiting groove 2111 to limit the rotation of the tongue body 211 relative to the connecting column 212, and at the moment, when the tongue body 211 is subjected to an acting force along the axial direction of the connecting column 212, the tongue body 211 can move along the axial direction of the connecting column 212; when the locking block 313 is in the unlocking position, the locking block 313 and the tongue body 211 are separated from each other, and the tongue body 211 can rotate relative to the connecting column 212 under the condition that a user performs a door opening action.
In other embodiments, the tongue 211 can be controlled to rotate relative to the connecting column 212 by an electric control manner.
In order to reduce the complexity and cost of the lock 100, in some embodiments, the transmission assembly 41 may be in transmission connection with the locking assembly 31 while in transmission connection with the second latch bolt assembly 22, that is, the transmission assembly 41 may drive the locking assembly to switch between the locked position and the unlocked position while driving the second latch bolt assembly 22 to move.
In other embodiments, the locking assembly 31 may be moved in an electrically controlled manner.
With continued reference to fig. 2 and 3, in some embodiments, the driving assembly 41 may further include a driving block 413 and an unlocking member 414.
The transmission block 413 may be connected to the first transmission member 411 and rotate in synchronization with the first transmission member 411. The unlocking member 414 is rotatably disposed on the bottom case 11 and located between the first transmission member 411 and the locking member 313. The unlocking member 414 has a first transmission part 4141 and a second transmission part 4142, the first transmission part 4141 is drivingly connected to the locking block 313, and the second transmission part 4142 is located on a rotation path of the transmission block 413 and selectively contacts or separates from the transmission block 413. Under the condition that the second transmission portion 4142 contacts the transmission block 413, the unlocking member 414 is pushed by the transmission block 413 to rotate in the first direction, and drives the locking assembly 31 to switch from the locking position to the unlocking position; when the second transmission portion 4142 is separated from the transmission block 413, the unlocking member 414 rotates in a direction opposite to the first direction and is reset, and drives the locking assembly 31 to switch from the unlocking position to the locking position. That is, when the lock 100 is in the locked state, the locking block 313 is in the locking position, and the transmission block 413 and the second transmission part 4142 are separated from each other; when the first transmission member 411 rotates and drives the transmission block 413 to rotate synchronously, the transmission block 413 rotates from a position far away from the second transmission portion 4142 to be in contact with the second transmission portion 4142, and continues to rotate under the driving of the first transmission member 411, so that the transmission block 413 can push the second transmission portion 4142 to rotate, the first transmission portion 4141 and the second transmission portion 4142 rotate synchronously, and the locking block 313 is driven to be switched from the locking position to the unlocking position, thereby unlocking the tongue body 211.
It should be noted that, in the embodiment of the present application, after the predetermined time t when the second latch bolt assembly 22 moves to the second position 222, the locking assembly 31 moves to the unlocking position, where t is greater than or equal to 0, so that when the second latch bolt assembly 22 is switched from the first position 221 to the second position 222, the locking member is switched from the locking position to the unlocking position, that is, the latch body 211 is unlocked after the second latch bolt assembly 22 is completely retracted, so as to ensure that when a user performs a door opening action, the main latch bolt is completely retracted, and a situation that the second latch bolt assembly 22 rebounds when the user performs the door opening action is avoided.
It will be appreciated that the above-described case can be subdivided into three cases.
Specifically, the first case is:
when the lock 100 is in the locked state, the first transmission element 411 receives external power to rotate, and drives the second transmission element 412 to rotate and simultaneously drives the transmission block 413 to synchronously rotate, that is, when the second transmission element 412 rotates and drives the shifting block 415 to drive the second latch bolt assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction close to the second transmission portion 4142. As shown in fig. 2, when second latch bolt assembly 22 is in second position 222, driver block 413 is also in a position spaced from second driver portion 4142; alternatively, as shown in fig. 3, when second latch bolt assembly 22 is in second position 222, driver block 413 may be in a position just contacting second driver portion 4142. The locking block 313 is still in the locked position. That is, locking assembly 31 is configured to remain in the locked position when second latch bolt assembly 22 is switched from first position 221 to second position 222.
The second case is:
referring to fig. 5, when the lock device 100 is in the locked state, the first transmission member 411 receives external power to rotate, and drives the second transmission member 412 to rotate, and simultaneously drives the transmission block 413 to rotate synchronously, that is, when the second transmission member 412 rotates and drives the dial block 415 to drive the second latch bolt assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction close to the second transmission portion 4142. When the second latch bolt assembly 22 is in the second position 222, the transmission block 413 may be in contact with the second transmission portion 4142, and the transmission block 413 drives the second transmission portion 4142 to rotate for a certain distance, so that the first transmission portion 4141 drives the locking block 313 between the locking position and the unlocking position. That is, locking assembly 31 is configured to be positioned between the locked position and the unlocked position when second latch bolt assembly 22 is switched from first position 221 to second position 222.
The third case is:
when the lock 100 is in the locked state, the first transmission element 411 receives external power to rotate, and drives the second transmission element 412 to rotate and simultaneously drives the transmission block 413 to synchronously rotate, that is, when the second transmission element 412 rotates and drives the shifting block 415 to drive the second latch bolt assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction close to the second transmission portion 4142. When the second latch bolt assembly 22 is in the second position 222, the transmission block 413 may be in contact with the second transmission part 4142 and drive the second transmission part 4142 to rotate for a longer distance, so that the first transmission part 4141 drives the locking block 313 to be just in the unlocking position. That is, the locking assembly 31 is configured to switch from the locked position to the unlocked position when the second latch bolt assembly 22 is switched from the first position 221 to the second position 222.
In the lock 100 provided in the embodiment of the application, in the unlocking process, after the second lock tongue assembly 22 is switched from the first position 221 extending out of the second lock hole 123 to the second position 222 accommodated in the accommodating cavity 13, the locking assembly 31 is switched from the locking position located in the locking tongue body 211 to the unlocking position separated from the tongue body 211, so that the first lock tongue assembly 21 is unlocked after the second lock tongue assembly 22 is completely retracted, and it is avoided that when a user performs a door opening operation, the second lock tongue assembly 22 is not completely retracted, and the first lock tongue assembly 21 is unlocked and retracted into the accommodating cavity 13, thereby causing the situation that the second lock tongue assembly 22 is mistakenly bounced after the door opening operation is completed.
