Referring to fig. 1-6, the present embodiment is a working principle of a subminiature cabinet lock: when the lock needs to be unlocked, when the lock receives an unlocking signal of the power control line 53, the driving motor 51 can drive the rotating rod 24 to rotate to the fixed position sensed by the reflecting ring 25 together through the PCB control board 52 according to the light sensing signal of the position of the reflecting ring 25, the inclined surface on the rotating rod 24 is matched with the inclined surface on the ejector rod 23 to enable the rotating rod 24 to be horizontally ejected, and the ejector lock rod 11 compresses the lock rod torsion spring 32, so that the hook 12 is released.

The hook torsion spring 33 is sleeved on the hook 12, and when the lock hook 12 is released, because the acting force of the hook torsion spring 33 is always outward, and the lock rod 11 is lifted to a certain height without interference, the hook is directly popped out, and the unlocking action is completed.

By placing the push block 14 inside the push block housing 13 and adding the compression spring 31, the push block can keep the outward pushing force and is fixed on the upper cover 2, the problem that the door can shake due to the processing or the reserved gap between the hook 12 and the door can be effectively prevented when the door is closed, and the push block can be used as the boosting force when the hook 12 is released.

When the lock needs to be closed and the lock receives a locking signal of the power control line 53, the driving motor 51 can drive the rotating rod 24 to rotate together to a fixed position sensed by the reflecting ring 25 through the PCB control board 52 according to a light sensing signal at the position of the reflecting ring 25, and the inclined surface on the rotating rod 24 is matched with the inclined surface on the ejecting rod 23, so that the rotating rod falls into and stops at the lowest point after passing through the highest point. The retractable silicon rubber 41 is compressed under the force of the locking lever torsion spring 32 and stops at the locking point position because there is no support of the ejector rod 23. At this time, the locking can be completed only by pushing the hook 12 in.

When the hook 12 is pushed in at the locking point, the locking sensing rod 26 and the retractable silica gel 41 are pressed in, the locking sensing rod 26 has an inclined matching surface with the locking detection trigger block 27 to promote the walking direction to change, and the detection switch trigger point 62 is pressed down to enable the PCB control board 52 to process feedback and be in a locked state.

Because the lock closing sensing rod 26 and the lock closing detection trigger block 27 have one compression spring 31, after the hook 12 is ejected, because the lock closing sensing rod 26 is not pressed, the second compression spring 34 will drive the lock closing sensing rod 26 and the lock closing detection trigger block 27 to reset, thereby releasing the detection switch trigger point 62 to bounce, and the PCB control board 52 processes and feeds back to an unlocked state.

Further explanation is needed to explain the action principle of the switch lock: the contact surface of the rotating rod 24 and the ejecting rod 23 is a bilateral symmetrical inclined plane, the inclined plane has a certain high point and a certain low point, and the outer layer of the ejecting rod 23 is provided with a limiting mechanism which can not rotate and can only translate. Therefore, when the high point of the ejecting rod 23 is at the same position as the high point of the rotating rod 24 after rotating for a certain angle, the ejecting rod 23 moves out of the control box assembly 3 to eject the lock rod 11 to release the hook 12, which is in the unlocking state.

And the two inclined surfaces are engaged when the high point of ejector rod 23 is located at the low point of rotary rod 24, and are retracted into control box assembly 3. The lock rod 11 presses down the ejector rod 23 and the retractable silicone rubber 41 under the action of the lock rod torsion spring 32, and the hook torsion spring 33 cannot be released out as long as the hook 12 is pushed in, so that the lock rod belongs to a lockable state.
