When the lock is closed, the hook assembly 2 rotates and slides along the sliding surface 4b, and pushes the stop block 4 to move in a straight line, and the hook assembly 2 stops rotating when the sliding surface contacts the stop surface 4c.

[0036] Furthermore, a slot 4e is provided on the side of the stop block 4 for engaging with the electromagnet assembly 6 .

[0037] Furthermore, the stop assembly 5 also includes a stop spring 4a, one end of which is connected to the stop spring connecting end 4f, and the other end is against the side wall of the lock cover assembly 1. The stop block 4 moves linearly, compressing or stretching the stop spring 4a, and the elastic force of the stop spring 4a can make the stop block 4 move linearly.

[0038] like Figure 2 , Figure 5 and Figure 6 As shown, preferably, the emergency rod 8 is bent, the connecting end 8a is inserted into the emergency rod connecting hole 6b of the electromagnet assembly 6, and the other end passes through the side wall of the lock cover assembly 1 and extends out of the lock cover assembly 1.

[0039] like Figure 1 and7 As shown, the lock cover assembly 1 includes an upper lock cover 1b and a lower lock cover 1a. The upper lock cover 1b is buckled on the lower lock cover 1a. The lower lock cover 1a is provided with a first fixed column 1c, a second fixed column 1d, a stop assembly slot 1e, an electromagnet assembly slot 1f, and an emergency rod slot 1h. The hook assembly 2 is installed on the first fixed column 1c and can rotate around the first fixed column 1c. The stop assembly 5 is installed in the stop assembly slot 1e and can move linearly along the stop assembly slot 1e. The electromagnet assembly 6 is installed in the electromagnet assembly slot 1f. The emergency rod 8 is installed in the emergency rod slot 1h and passes through the emergency hole 1k.

[0040] Furthermore, the upper locking cover 1b and the lower locking cover 1a are integrally formed by injection molding, and the first fixing column 1c, the second fixing column 1d, the stop assembly slot 1e, the electromagnet assembly slot 1f, and the emergency rod slot 1h are directly injection molded.

[0041] Furthermore, the lower locking cover 1a also includes a sliding groove 1g, which is connected to the stop assembly groove 1e and the electromagnet assembly groove 1f. The connecting rod 6a of the electromagnet assembly 6 is connected to the slot 4e of the stop assembly 5 through the sliding groove 1g and can move in a straight line along the sliding groove 1g.

[0042] like Figure 2 and Figure 3 As shown, this embodiment further includes a micro switch 10 , which is disposed on the second fixing column 1 d and can contact the micro switch contact end 3 e of the hook 3 . The rotation of the hook 3 can trigger the micro switch 10 .

[0044] After the unlocking command is issued, the electromagnet assembly 6 is energized to drive the connecting rod 6a to move linearly to the right, and the connecting rod 6a is disengaged from the slot 4e. The stop block 4 moves linearly downward under the elastic force of the stop spring 4a to unlock the hook 3. The hook 3 rotates clockwise under the action of the torsion spring 3a, so that the lock hook 7 is disengaged and the cabinet door 7a opens.

[0045] When locking, the lock hook 7 pushes the hook groove 3c, causing the hook 3 to rotate counterclockwise along the sliding surface 4b and compressing the stop spring 4a. When the hook 3 rotates over the sliding surface 4b and is about to contact the stop surface 4c, the stop block 4 moves upward in a straight line under the action of the elastic force. When the stop spring 4a is in a stretched state, the stop surface 4c contacts the stop end 3d of the hook 3, locking the hook 3. At this time, the electromagnet assembly 6 is reset, the connecting rod 6a is inserted into the slot of the stop block 4, and the cabinet door 7a is closed.

[0046] In an emergency, the toggle end 8b of the emergency lever 8 is moved upward. Due to the lever principle, the emergency lever 8 rotates around the fulcrum on the lower lock cover 1a, and the connecting end 8a presses the electromagnet assembly 6 to the right, causing the electromagnet assembly to move linearly to the right. The connecting rod 6a disengages from the slot 4e of the stop block 4, and the stop block 4 moves linearly downward under the elastic force of the stop spring 4a, unlocking the hook 3. The hook 3 rotates clockwise under the action of the torsion spring 3a, disengaging the lock hook 7, and the cabinet door 7a opens.
