[0015] By adopting the above technical solution, since the modular microcomputer protection device occupies a large internal space of the switch cabinet and it is economically inefficient to expand the volume of the switch cabinet, the anti-theft performance of this type of high-voltage switch cabinet is poor, making the cabinet door easy to be opened and the internal circuits easy to be touched.

[0016] The present application realizes locking of the cabinet door and the cabinet body by clamping the retarder wheel and 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.

[0022] By adopting the above technical solution, when the prompt ball slides to the prompt groove, the prompt spring pushes the prompt ball out, causing the prompt ball to collide with the bottom of the prompt groove, thereby prompting the maintenance personnel to unlock the device.

The rotating plate 808 is provided with a belt and is linked to the rotating block through the belt.

[0063] The implementation principle of the embodiment of the present application is as follows: the connection base 6 is plugged into the plug on the control component 301 of the microcomputer protection device 3, and the connection base 6 is fixedly connected to the control component 301, which can effectively prevent the connection base 6 from falling off. By inserting a plurality of wires for connecting the high-voltage switch device 2 and the module component 302 in the harness head 9, it is avoided that there are too many wires at the cabinet door 102 to cause clutter, and the wires are connected to the control component 301 of the microcomputer protection device 3 through the harness head 9 and the connection base 6, which can effectively prevent the plug connector of the wire from being accidentally touched, causing the wire to fall off.

[0064] 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, and the microcomputer protection device 3 can be further prevented from being vibrated.

[0065] 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, and 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 so that the positioning block 25 further extends into the card slot 28, resulting in the pressing shell 801 being carded with the anti-theft disk 803.

[0066] 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, and 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.

[0067] Turning the key 806 causes the rotating disk 808 to drive the rotating rod 805 to rotate, and causes the unlocking block 702 to slide toward the slow-speed wheel 707, and the slow-speed wheel 707 is pushed out of the fixing 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.

[0068] After successful unlocking, the limit spring 703 pulls back the unlocking block 702, 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 pressing shell 801 is pushed out of the positioning slot 26 by the reset spring 21, 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.

[0069] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
