[0031] The driving mechanism rotates forward, thereby driving the lock tongue mechanism to move forward and be inserted into the slot 6, thereby realizing the rotation limit between the lock body assembly and the screw seat (that is, the lock body assembly and the screw seat are fixed as one body), so that the screw lock as a whole can rotate relative to the cabinet door panel 24, thereby locking the cabinet door panel 24 on the power equipment, or unlocking the cabinet door panel 24 from the power equipment;

[0032] The driving mechanism rotates in the opposite direction, causing the lock tongue mechanism to move backward and reset and withdraw from the slot 6 under the elastic force of the elastic member 11, thereby releasing the rotation limit between the lock body assembly and the screw seat, allowing the lock body assembly to rotate relative to the screw seat and the cabinet door panel 24, that is, the lock body assembly rotates idly, preventing the screw seat from loosening and separating from the cabinet door panel 24, thereby causing the cabinet door panel 24 to be accidentally opened, ensuring that the screw lock of the cabinet door panel 24 will not be removed when the cabinet door panel 24 is locked, thereby ensuring the locking security of the cabinet door panel 24 and eliminating safety hazards.

[0033] In this embodiment, the lock main body assembly includes an outer sleeve 1 and a main body fixedly installed in the outer sleeve 1. A groove is formed on the outer end side of the outer sleeve 1.

[0035] In this embodiment, an annular groove 21 is formed on the circumferential inner wall of the outer sleeve 1 near one end of the barrel mouth, and a C-shaped ring 22 is detachably installed at the annular groove 21. The base 4 is located between the C-shaped ring 22 and the main body, ensuring the assembly convenience and stability between the lock body components on the screw seat.

[0036] In this embodiment, the main body includes a main body seat 2 and a turntable 3 fixedly installed on the side of the base 4 facing the main body seat 2. A rotating shaft 23 is arranged at the center of one side of the turntable 3, and a positioning groove 15 is arranged at the center of one side of the base 4. The rotating shaft 23 is rotatably arranged in the positioning groove 15, thereby improving the stability and accuracy of the rotation of the lock body assembly on the screw seat.

[0037] In this embodiment, a stepped concave surface 20 is formed on the circumferential inner wall of the outer sleeve 1, and the turntable 3 and the base 4 are axially limited together at the stepped concave surface 20, thereby improving the assembly accuracy and rotation stability of the screw lock.

This arrangement improves the locking accuracy and service life of the lock tongue mechanism.

[0040] The use process of the screw lock in this embodiment is as follows:

[0041] Installation process of the screw lock: When the motor 9 receives the unlocking information, the motor 9 rotates forward and drives the eccentric wheel 10 to rotate forward at the same time, so that the eccentric wheel 10 drives the lock tongue mechanism to move forward and insert into the slot hole 6. At this time, the spring is compressed and stores energy, and the lock body assembly and the screw seat are integrated and cannot rotate relative to each other, so that the whole screw lock can rotate relative to the cabinet door panel 24. By rotating the screw lock clockwise, the screw 5 can be screwed into the screw hole on the cabinet door panel 24 until the screw 5 is tightened with the fixed surface of the electrical equipment. Then, a locking signal is sent to the motor 9 in the screw lock. The motor 9 rotates backward and drives the eccentric wheel 10 to rotate backward at the same time. Under the elastic force of the spring, the lock tongue mechanism moves backward and resets and exits outside the slot hole 6, thereby releasing the rotational limit between the lock body assembly and the screw seat, so that the lock body assembly can rotate relative to the screw seat and the cabinet door panel 24, that is, the lock body assembly and the screw seat are no longer integrated, and the lock body assembly will only rotate idly alone, preventing the screw seat from being unscrewed and detached from the cabinet door panel 24, thus avoiding the situation of accidental opening of the cabinet door panel 24, ensuring that the screw lock cannot be removed when the cabinet door panel 24 is in the locked state, and further ensuring the locking safety of the cabinet door panel 24 and eliminating potential safety hazards.

[0042] Removal process of the screw lock: When the motor 9 receives the unlocking information, the motor 9 rotates forward and drives the eccentric wheel 10 to rotate forward at the same time, so that the eccentric wheel 10 drives the lock tongue mechanism to move forward and insert into the slot hole 6. At this time, the spring is compressed and stores energy, and the lock body assembly and the screw seat are integrated and cannot rotate relative to each other, so that the whole screw lock can rotate relative to the cabinet door panel 24. Then, by rotating the screw lock counterclockwise, the screw 5 can be screwed out of the fixed surface of the electrical equipment and the screw hole on the cabinet door panel 24, thereby removing the screw lock.
