As shown in fig. 2, when the second latch bolt assembly 22 is in the first position 221, the second latch bolt assembly 22 extends out of the second lock hole 123 to back lock the security door in the closed state, thereby further enhancing the security of the security door; as shown in fig. 3, when second latch bolt assembly 22 is in second position 222, second latch bolt assembly 22 is received within receiving cavity 13.
To actuate second latch assembly 22 to switch between first position 221 and second position 222, lock 100 may further include a transmission assembly 41, transmission assembly 41 drivingly coupled to second latch assembly 22, and transmission assembly 41 configured to receive external power and to actuate second latch assembly 22 from first position 221 to second position 222.
In some embodiments, the transmission assembly 41 may include a first transmission 411 and a second transmission 412. Wherein the first transmission member 411 is rotatably disposed on the bottom shell 11, and is configured to rotate when receiving external power, and is in transmission connection with the locking assembly 31, so as to drive the locking assembly 31 to switch from the locking position to the unlocking position; the second transmission member 412 is drivingly connected between the first transmission member 411 and the second latch assembly 22, and the first transmission member 411 rotates when receiving external power and drives the second transmission member 412 to rotate the second latch assembly 22 to switch from the first position 221 to the second position 222.

It will be appreciated that the second transmission 412 may be one of a variety of transmission means for transmitting the power of the first transmission 411 to the second latch assembly 22. For example, in the embodiment shown in fig. 3, the second transmission member 412 may be rotatably disposed on the bottom shell 11, at least part of the edge of the first transmission member 411 is provided with a first tooth 4111, at least part of the edge of the second transmission member 412 is provided with a second tooth 4121, and the first transmission member 411 and the second transmission member 412 are meshed with each other through the first tooth 4111 and the second tooth 4121, so as to achieve the purpose of transmission connection.
In other embodiments, the rotation axis of the second transmission member 412 may coincide with the rotation axis of the first transmission member 411, and the first transmission member 411 and the second transmission member 412 may be connected to each other, so that the first transmission member 411 may drive the second transmission member 412 to rotate synchronously when rotating.
Referring to fig. 2 and 3 again, in some embodiments, the transmission assembly 41 may further include a shift block 415, the shift block 415 may be coaxially disposed with the second transmission member 412, and the shift block 415 may be connected between the second transmission member 412 and the second latch assembly 22, when the second transmission member 412 rotates, the second transmission member 412 may drive the shift block 415 to rotate synchronously, and when the shift block 415 rotates, the shift block 415 drives the second latch assembly 22 to move.
Specifically, a surface of the second transmission member 412 facing the dial 415 may be provided with a sliding groove 4122, the sliding groove 4122 may extend through the second transmission member 412, the sliding groove 4122 may extend around the rotation axis of the second transmission member 412, and the front and rear ends of the sliding groove 4122 are not communicated. The surface of the shifting block 415 facing the second transmission member 412 may be provided with a slider 4151, the slider 4151 slidably extending into the slide groove 4122. When the sliding block 4151 can move in the sliding groove 4122 under the condition that the second transmission assembly 41 rotates, the second transmission assembly 41 and the shifting block 415 are separated from each other, and the shifting block 415 is stationary; when the sliding block 4151 abuts against the side walls at two ends of the sliding groove 4122, the first transmission member 411 is connected with the shifting block 415, and at this time, the second transmission assembly 41 can drive the shifting block 415 to rotate synchronously, and the shifting block 415 drives the second latch assembly 22 to move when rotating.
In other embodiments, the second latch assembly 22 may be directly in contact with and connected to the second transmission member 412, and the first transmission member 411 drives the second transmission member 412 to move the second latch assembly 22.
In some embodiments, the first transmission member 411 may be connected to the door handle through a square shaft, and when the door handle rotates, the first transmission member 411 drives the second transmission member 412 to rotate, and after the side wall of the sliding chute 4122 abuts against the sliding block 4151, the second transmission member 412 drives the shifting block 415 to rotate, so as to drive the second latch assembly 22 to switch from the first position to the second position; in the case that the door handle is reversely rotated and reset, the first driving member 411 drives the second driving member 412 to reversely rotate, and the slider 4151 is separated from the side wall of the slide groove 4122 and slides in the slide groove 4122.
With continued reference to fig. 2 and 3, in some embodiments, the lock 100 may further include a reset member 51 and a locking device.
The reset member 51 is configured to continuously provide the second latch assembly 22 with a reset force extending out of the second latch hole 123, i.e., the reset member 51 continuously provides the second latch assembly 22 with a reset force from the second position 222 toward the first position 221. When the first transmission member 411 receives external power and transmits the external power to the second latch assembly 22, so that the second latch assembly 22 is switched from the first position 221 to the second position 222, the force transmitted from the first transmission member 411 to the second latch assembly 22 needs to overcome the restoring force, so as to achieve the purpose of switching the second latch assembly 22 from the first position 221 to the second position 222.
The locking device is disposed in the accommodating cavity 13 and is used for locking the second latch assembly 22 at the second position 222, that is, when the second latch assembly 22 is switched from the first position 221 to the second position 222, the locking device locks the second latch assembly 22 at the second position 222, so as to prevent the second latch assembly 22 from rebounding from the second position 222 to the first position 221 under the action of the reset force after the first transmission member 411 is reset.
In other embodiments, the position of second latch bolt assembly 22 may be determined by first transmission assembly 41.
Referring to fig. 1, 2 and 3, the first latch bolt assembly 21 mainly includes a latch body 211 and a connecting post 212, wherein the connecting post 212 is slidably disposed along an axial direction of the first lock hole 122 and hinged to one end of the connecting post 212 near the guide plate 12, and the latch body 211 can selectively extend out of the first lock hole 122 or be accommodated in the accommodating cavity 13, i.e. when the security door is in a closed state, the latch body 211 extends out of the first lock hole 122 and extends into a locking slot disposed in the door frame and abuts against an inner wall of the locking slot; when a user performs a door opening operation, the tongue 211 may be accommodated in the accommodating chamber 13.
It should be noted that the tongue 211 provided in this embodiment can rotate around an axis parallel to the guide plate 12 and the bottom case 11 at the same time, thereby realizing bidirectional opening and closing of the door. Specifically, when the door is in a state of closing but allowing the user to perform the door opening action, that is, in a state that the tongue body 211 extends out of the first lock hole 122 but can be retracted into the accommodating cavity 13, the tongue body 211 abuts against the side wall of the locking groove, and when the user rotates the anti-theft door in the forward direction or the reverse direction at this time, the side wall of the locking groove applies a force to the tongue body 211, so that the tongue body 211 is accommodated into the accommodating cavity 13, and the door opening action is realized.
With continued reference to fig. 1,2 and 3, the locking assembly 31 is disposed in the accommodating cavity 13, when the locking assembly 31 is in the locking position, the locking assembly 31 contacts with the tongue 211 and can limit the tongue 211 to rotate relative to the connecting post 212, and when the locking assembly 31 is in the unlocking position, the locking assembly 31 and the tongue 211 are separated from each other, and at this time, under the condition that a user performs a door opening action, the tongue 211 can rotate relative to the connecting post 212.
Referring to fig. 4, in order to enable the tongue 211 to selectively rotate or stand still relative to the connecting post 212, in one embodiment, the tongue 211 may be provided with a limiting groove 2111, and the shape of the limiting groove 2111 may be other than a circular shape, such as a triangle or a direction, which is not limited herein. Referring to fig. 2 and 3 again, the locking assembly 31 may include a locking block 313, the locking block 313 may be slidably disposed on the bottom shell 11, and the locking block 313 has an unlocking position and a locking position, and may 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 limit groove 2111, and the surface of the locking block 313 is attached to the side wall of the limit groove 2111 to limit the rotation of the tongue 211 relative to the connecting column 212, at this time, when the tongue 211 receives a force along the axial direction of the connecting column 212, the tongue 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 211 are separated from each other, and the tongue 211 can rotate relative to the connecting post 212 under the condition that the user performs the door opening action.
In other embodiments, the tongue 211 may be controlled to rotate relative to the post 212 by an electronically controlled manner.
To reduce the complexity and cost of the lock 100, in some embodiments, the drive assembly 41 is drivingly connected to the second latch bolt assembly 22 and the lock assembly 31 is drivingly connected, i.e., the drive assembly 41 drives the second latch bolt assembly 22 and the lock assembly is driven to switch between the unlocked position.
In other embodiments, the locking assembly 31 may also be moved in an electronically controlled manner.
With continued reference to fig. 2 and 3, in some embodiments, the transmission assembly 41 may further include a transmission block 413 and an unlocking member 414.
The driving block 413 may be connected to the first driving member 411 and rotate in synchronization with the first driving 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 block 313. The unlocking member 414 has a first transmission portion 4141 and a second transmission portion 4142, the first transmission portion 4141 is in transmission connection with the locking block 313, and the second transmission portion 4142 is located on the rotation path of the transmission block 413 and selectively contacts or separates from the transmission block 413. Then, under the condition that the second transmission part 4142 is in contact with the transmission block 413, the unlocking piece 414 rotates along the first direction under the pushing of the transmission block 413, and drives the locking assembly 31 to switch from the locking position to the unlocking position; with the second transmission portion 4142 separated from the transmission block 413, the unlocking member 414 rotates and resets in a direction opposite to the first direction, and drives the lock assembly 31 to switch from the unlock position to the lock position. That is, when the lock 100 is in the locked state, the lock block 313 is in the locked position, and the transmission block 413 and the second transmission portion 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 away from the second transmission portion 4142 to 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 rotates synchronously with the second transmission portion 4142, and the locking block 313 is driven to switch from the locking position to the unlocking position, so as to unlock the tongue 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, 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 latch member is switched from the latch position to the latch release position, that is, the latch body 211 is released after the second latch bolt assembly 22 is completely retracted, so as to ensure that the main latch bolt is completely retracted when the user performs the door opening operation, and avoid the condition that the second latch bolt assembly 22 rebounds when the user performs the door opening operation.
It will be appreciated that the above case can be subdivided into three cases.
Specifically, the first case is:
When the lock 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 shifting block 415 to drive the second latch assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction approaching the second transmission portion 4142. As shown in fig. 2, when the second latch bolt assembly 22 is in the second position 222, the transmission block 413 is also in a position separated from the second transmission portion 4142; alternatively, as shown in fig. 3, when the second latch bolt assembly 22 is in the second position 222, the transmission block 413 may be in a position just in contact with the second transmission portion 4142. The lock 313 is still in the locked position. That is, the locking assembly 31 is configured to remain in the locked position when the second latch bolt assembly 22 is switched from the first position 221 to the second position 222.
The second case is:
referring to fig. 5, when the lock 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, i.e. when the second transmission member 412 rotates and drives the shift block 415 to drive the second latch assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction approaching to the second transmission portion 4142. When the second latch bolt assembly 22 is at 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 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, the locking assembly 31 is configured to be positioned between the locked and unlocked positions when the second latch bolt assembly 22 is switched from the first position 221 to the second position 222.
The third case is:
When the lock 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 shifting block 415 to drive the second latch assembly 22 to switch from the first position 221 to the second position 222, the transmission block 413 rotates in a direction approaching the second transmission portion 4142. When the second latch bolt assembly 22 is at the second position 222, the transmission block 413 may be in contact with the second transmission portion 4142 and drive the second transmission portion 4142 to rotate a longer distance, so that the first transmission portion 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 as the second latch bolt assembly 22 switches from the first position 221 to the second position 222.
In the lock 100 provided in the embodiment of the present application, in the unlocking process, after the second latch bolt 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 at the locking tongue body 211 to the unlocking position separated from the tongue body 211, so that after the second latch bolt assembly 22 is fully retracted, the first latch bolt assembly 21 is unlocked, and the situation that the second latch bolt assembly 22 is not fully retracted when a user performs a door opening action, and the first latch bolt assembly 21 is unlocked and retracted into the accommodating cavity 13, thereby causing the situation that the second latch bolt assembly 22 is flicked after the door opening action is completed is avoided.
