[0033] Working principle:

[0034] The personnel use screws to fix the lock body box 1 on the switch door, so that the round block is rotated and connected to the inner end surface of the switch door. The front end of the rectangular rod is fixedly clamped in the rectangular hole, so that the switch door is closed in the cabinet box. Then, the lifting handle 3 is held and rotated into the hole of the closing cavity 2. At this time, the blocking plate rotates into the cabinet box, and the blocking plate contacts the folded edge of the cabinet box. The switch door and the cabinet box are in a closed and locked state, and the lifting handle 3 is pushed to move into the closing cavity 2. At this time, the torsion block 17 rotates on the rotation shaft 16. When the sliding inclined surface 22 contacts the driving inclined surface 21, Continue to move the lifting handle 3 into the closing chamber 2, the driving inclined surface 21 will slide on the sliding inclined surface 22, and the interception block 8 will push the sliding block 7 to slide upward along the bearing chamber 5, and the compression spring 12 will continue to compress. When the rear end face of the interception block 8 is located on the front side of the front end face of the stopper 14, due to the rebound force of the compression spring 12, the interception block 8 quickly slides to the front section face of the stopper 14 to block it, and at the same time, the lock core body 23 is accurately inserted into the fixing ring 27, and each insert block 29 is also inserted into the corresponding driving port 28, and the torsion spring accumulates force;

[0035] When the cabinet box needs to be opened, the installation cover 26 moves to one side, the key is inserted into the lock core body 23, the driving key drives the lock core body 23 to rotate, the insert block 29 drives the fixing ring 27 to rotate through the driving port 28, and the arc surface of the toggle rod 18 slides against the contact plate 19. When the lock core body 23 continues to rotate, the arc surface of the toggle rod 18 slides onto the push inclined surface 20, and pushes the sliding block 7 and the intercepting block 8 to move upward, the compression spring 12 continues to compress, and when the rear end surface of the intercepting block 8 and the front end surface of the stopper 14 are in contact with each other, the locking spring 12 is pressed against the locking plate 19, and the locking plate 19 is locked. When they are in the same plane, due to the reaction force of the torsion spring, the lifting handle 3 is quickly ejected from the closing chamber 2, and the person holds the lifting handle 3 and rotates it to one side, so that the blocking plate is no longer in contact with the folded edge of the cabinet box, and the cabinet box is opened. Due to the rebound force of the compression spring 12, the toggle rod 18 is restored to its initial state, so that the cabinet lock can be quickly opened, and the device is easy to operate and has higher safety. The installation cover 26 can also protect the lock core body 23 to prevent dust and impurities from entering the lock core;

[0036] When a person forgets to bring the key, he or she takes out the mobile phone and scans the QR code 15, and starts the controller through the small program on the mobile phone. The controller starts the telescopic rod 10 to retract, and the pull plate 11 moves the push plate 9 upward, and the compression spring 12 continues to compress. When the rear end face of the interception block 8 and the front end face of the block 14 are in the same plane, due to the reaction force of the torsion spring, the pulling handle 3 at this time quickly pops out from the closing cavity 2. The person holds the pulling handle 3 and turns it to one side, and the blocking plate no longer contacts the folded edge of the cabinet box, so that the cabinet box is opened. At the same time, the telescopic rod 10 and the interception block 8 are automatically reset, realizing intelligent control of the opening of the switch door, and also providing a variety of operation methods. For example, when the key is lost or forgotten, the cabinet box can also be quickly opened, which is more practical.
