[0015] The present application realizes locking of the cabinet door and the cabinet body by engaging the retarder wheel with the fixed groove, and drives the unlocking tool to slide toward the retarder wheel by rotating the rotating rod, so that the unlocking tool pushes the retarder wheel out of the fixed groove, thereby realizing unlocking of the cabinet body and the cabinet door.

After unlocking, the limit spring pulls the unlocking block back, and at the same time, the torsion spring drives the rotating rod to rotate in the opposite direction. The card plate abuts against the inner teeth and drives the pressing shell to rotate, so that the positioning block moves out of the card slot into the positioning slot, and then the pressing shell is pushed out of the positioning slot by the reset spring, thereby realizing the reset of the anti-accidental touch locking device.

The end of the rotating rod 805 is fixedly connected to a gear, and the lower end surface of the unlocking block 702 is provided with a tooth groove, and the gear meshes with the tooth groove.

[0048] refer to Figure 7 、 Figure 9 A lock hole 31 is provided on the cabinet body 1 on one side of the pressing shell 801, and a key 806 is inserted into the lock hole 31. A travel groove 32 with two curved nodes is provided on the inner wall of the lock hole 31, and a prompt groove 33 is provided at the curved node of the travel groove 32.

[0049] Key 806 comprises a square section and a circular section. The circular section's cross-sectional diameter matches the width and length of the cross-sectional area at the directional end. The circular section defines an arcuate slot 34, within which a warning ball 35 is rotatably connected. A warning spring is fixed to the bottom of the slot, with the other end of the spring contacting the warning ball 35. The warning ball 35 slides along the travel slot 32. When it reaches the warning slot 33, the warning spring pushes the warning ball 35 outward, causing it to collide with the bottom of the slot.

[0050] refer to Figure 7 A positioning disk 807 axially arranged with the lock hole 31 is rotatably connected to the unlocking box 19, and a rotating disk 808 rotatably connected to the unlocking box 19 is axially arranged on the side of the positioning disk 807 away from the lock hole 31, and square holes consistent with the outer wall of the square end of the key 806 are provided in the rotating disk 808 and the positioning disk 807, and the key 806 can be inserted into the square hole.

[0051] The positioning plate 807 is coplanar with the anti-theft plate 803, and external teeth are fixedly connected to the outer walls of the anti-theft plate 803 and the positioning plate 807, which mesh with the anti-theft plate 803. A rotating block is axially fixed to the rotating rod 805, and the rotating block is coplanar with the rotating plate 808. The rotating plate 808 is provided with a belt and is linked to the rotating block via the belt.

[0052] The working principle of the embodiment of the present application is as follows: the connector 6 is plugged into the plug on the control assembly 301 of the microcomputer protection device 3, and the connector 6 and the control assembly 301 are fixedly connected, which can effectively prevent the connector 6 from falling off. By inserting a plurality of wires for connecting the high-voltage switchgear 2 and the module assembly 302 into the wiring harness 9, the excessive wires at the cabinet door 102 are avoided from causing clutter. The wires are connected to the control assembly 301 of the microcomputer protection device 3 through the wiring harness 9 and the connector 6, which can effectively prevent the wire plug from being accidentally touched and causing the wire to fall off.

[0053] When the cabinet door 102 is closed after the wire connection is completed, the slow wheel 707 gradually approaches the slow platform 701 and slides on the sliding surface of the slow platform 701, thereby reducing the speed when closing the cabinet door 102, which can effectively prevent the microcomputer protection device 3 from falling off due to rapid closure. The slow wheel 707 slides along the sliding surface for a distance and then slides into the fixed groove 15. It is located between the inner wall of the fixed groove 15 and the unlocking block 702, and the diameter of the slow wheel 707 is smaller than the height of the fixed groove 15, so that one side of the slow wheel 707 is engaged with the fixed groove 15 and the other side is in conflict with the inclined surface of the unlocking block 702. At the same time, the impact of the slow wheel 707 can be effectively reduced by the inclined surface and the limit spring 703, further preventing the microcomputer protection device 3 from being vibrated.

[0054] When the maintenance personnel need to open the cabinet door 102, they can insert the key 806 into the lock hole 31 and rotate it. After the key 806 is inserted, the square section of the key 806 is inserted into the square hole of the positioning plate 807. At this time, the prompt ball 35 is partially embedded in the travel groove 32. The rotation of the key 806 causes the prompt ball 35 to rotate along the travel groove 32. When the prompt ball 35 rotates to the prompt groove 33, the positioning groove 26 on the positioning plate 807 and the positioning block 25 on the pressing shell 801 are aligned. At this time, the maintenance personnel can push the pressing shell 801 inward to make the positioning block 25 extend into the positioning groove 26. At the same time, the pressing shell 801 is rotated to make the positioning block 25 further extend into the locking groove 28, causing the pressing shell 801 to be locked with the anti-theft disk 803.

[0055] At the same time, the rotating rod 805 extends into the deceleration platform 701 and meshes with the tooth groove of the unlocking block 702 through the gear. The key 806 continues to slide along the travel groove 32, so that the square section of the key 806 passes through the square hole of the positioning plate 807 and extends into the direction hole of the rotating plate 808. At this time, the round section of the key 806 is inserted into the positioning plate 807. When the direction section of the key 806 extends into the square hole of the rotating plate 808, the prompt ball 35 collides with the bottom of the prompt groove 33 to prompt the maintenance personnel to proceed to the next step of unlocking.

[0056] Turning the key 806 causes the rotating disk 808 to rotate the rotating rod 805, causing the unlocking block 702 to slide toward the slow-speed wheel 707, and the slow-speed wheel 707 is pushed out of the fixed groove 15 through the inclined surface of the unlocking block 702. At the same time, when the rotating rod 805 rotates, the torsion spring 29 rotates synchronously and continues to twist the potential energy.

[0057] After successful unlocking, the limit spring 703 pulls the unlocking block 702 back, and at the same time the torsion spring 29 drives the rotating rod 805 to rotate in the opposite direction, the card plate 22 abuts against the inner tooth 24 and drives the pressing shell 801 to rotate, so that the positioning block 25 moves out of the card slot 28 to the positioning slot 26, and then the reset spring 21 pushes the pressing shell 801 out of the positioning slot 26, thereby realizing the reset of the anti-accidental touch locking device 4, and at the same time the key 806 can be directly pulled out from the lock hole 31.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
