This is done to prevent the latching pin from being subjected to the side friction of the latch 1222, thereby reducing the load on the driving member 143 and increasing the life of the driving member 143; the output shaft of the driving member 143 is electrically rotated to drive the first conical tooth 144 to rotate, and the second conical tooth 145 is driven to rotate through gear tooth engagement, the driving portion 1451 of the second conical tooth 145 rotates a certain angle along the inner wall of the sliding groove 1421, so that the rotational motion of the second conical tooth 145 is converted into the translational motion of the locking pin, the locking pin is completely retracted into the lock body 110, so that the locking pin is moved from the locking position to the unlocking position, at this time, the sensing portion 1423 of the locking pin extends into the second sensing switch 182, the sensing portion 1423 can be sensed by the second sensing switch 182, and the sensing portion 1423 cannot be sensed by the first sensing switch 181. The electronic circuit 150 controls the driver 143 to stop rotating and the latch pin remains in the unlocked position.

In the embodiment shown in fig. 7, when the latch 1222 is ejected out of the mounting slot 111 without a computer key for latching, the inductive magnetic steel 186 on the handle body 121 is far away from the inductive range of the hall element 185, and the hall element 185 cannot detect the magnetic steel, at this time, the electronic circuit 150 determines that the latch 1222 has been completely ejected out of the lock body 110, and the electronic circuit 150 controls the driving member 143 to rotate, so that the latching pin is switched from the unlocking position to the latching position. When the first sensing switch 181 senses the sensing part 1423, the electronic circuit 150 controls the driving member 143 to stop rotating, and the locking pin is maintained at the locking position. Specifically, when the operator presses the handle assembly 120 into the mounting slot 111, the sidewall of the latch tab 1222 abuts on the wedge-shaped slope 1422 of the latching pin, thereby pushing the latching pin to move into the lock body 110, and due to the reverse latching action of the driving member 143 and the transmission assembly, the latching pin is stationary with respect to the electronic latching assembly 140, so that the latch tab 1222 pushes the electronic latching assembly 140 to move as a whole. When the handle assembly 120 is completely pressed into the mounting groove 111, the electronic locking assembly 140 is pushed by the elastic force of the reset member 160 toward the initial position, so that the locking pin is stopped on the retreating path of the locking tongue 1222, the locking tongue 1222 cannot move, and the handle assembly 120 is locked at the locking position, thereby completing the whole locking process.
In an embodiment not shown in the drawings, when the computer key is required to be locked, the operator inserts the computer key into the wireless power supply module 130, the computer key wirelessly communicates with the electronic circuit 150, and the identity of the computer key is identified through the ID code collecting circuit. When the operator presses the handle assembly 120 into the mounting groove 111 completely, the magnetic induction magnet 186 is close to the hall element 185, and the hall element 185 can detect the magnetic induction magnet 186, and meanwhile, when the operator continuously presses the handle body 121, the protrusion 1211 on the handle body 121 triggers the button switch 183 through the button assembly 184 to change states, and then the electronic circuit 150 controls the driving member 143 to rotate. This is done to ensure that the handle assembly 120 has been fully pressed into the mounting slot 111 and that movement of the latching pin is not impeded by the latch bolt 1222. When the first sensing switch 181 senses the sensing portion 1423, the electronic circuit 150 controls the driving member 143 to stop rotating, the latching pin is kept at the latching position, so that the latching pin is stopped on the backward path of the latch 1222, the latch 1222 cannot move backward, and the handle assembly 120 is locked at the latching position, thereby completing the entire latching process.
In this embodiment, during emergency unlocking, the lock core dust cover 123 is rotated, the lock core 1221 is exposed, the emergency unlocking key is inserted into the lock core 1221, the emergency unlocking key is rotated to drive the lock core 1221 to rotate by a certain angle, thereby driving the lock tongue 1222 to rotate to the emergency unlocking position from the emergency locking position, the clamping part 12221 is staggered by a certain angle with the locking pin, the lock tongue 1222 does not stop the locking pin any more, the handle is flipped out of the installation groove 111 relative to the lock body 110 under the effect of the torsion spring 172, the intelligent cabinet lock is in an unlocking state, the rotating handle can drive the rotating shaft 171 to rotate at the moment, thereby driving the steel bolt to rotate by a certain angle, and the emergency unlocking operation is completed.
