[0023] Please refer to Figure 3 , the change-over switch main body 201 is provided inside the cabinet slot 2. An indicator light 202 is fixedly connected inside the cabinet slot 2. A terminal block 203 is fixedly connected inside the cabinet slot 2.
[0024] Please refer to Figures 3-4 , the protection mechanism 3. The protection mechanism 3 includes a positioning ring 301, a rotating rod 302, a connecting arm 303, a protection cap 304, a locking arm 305, a locking plate 306, a limiting groove 307, a slot 308, a locking rod 309 and a padlock 310. The positioning ring 301 is fixedly connected to the side wall of the cabinet slot 2. The rotating rod 302 is rotatably connected inside the positioning ring 301. The connecting arm 303 is fixedly connected to the rotating rod 302. The protection cap 304 is fixedly connected to the outer end of the connecting arm 303. The locking arms 305 are fixedly connected to both ends of the rotating rod 302. The locking plate 306 is fixedly connected to the inner side of the cabinet slot 2. The limiting groove 307 is opened at the front end of the locking plate 306. The slot 308 is penetrated and opened on one side of the locking plate 306. The locking rod 309 is slidably inserted inside the slot 308. The padlock 310 is fixedly inserted at one end of the locking rod 309.

The locking rod 309 penetrates through the front end of the limiting groove 307.
[0025] By providing the protective cap 304 to cover the main body 201 of the reverse switch to prevent other personnel from rotating the main body 201 of the reverse switch, by providing the positioning ring 301, the rotating rod 302 and the connecting arm 303, the multiple protective caps 304 of a single group can be controlled simultaneously, and by providing the locking arm 305, the locking plate 306, the limiting groove 307, the slot 308, the locking rod 309 and the padlock 310, the rotating rod 302 and the protective cap 304 can be locked to prevent other personnel from privately rotating the main body 201 of the reverse switch when the controller is not present.
[0026] Working principle: When a change-over switch for controlling a rail transit train is in use, in the initial state, first, the door panel 102 is rotatably connected to the front of the reverse switch cabinet 1 through the hinge 101. The observation window 103 opened on the door panel 102 can observe the main body 201 of the reverse switch and the indicator light 202 arranged in the cabinet slot 2, so as to observe the operating state of the internal equipment while providing protection. The positioning ring 301 arranged on the inner wall of the cabinet slot 2 rotatably connects the rotating rod 302, the connecting arm 303 and the protective cap 304, and the protective cap 304 covers the main body 201 of the reverse switch. The locking arms 305 fixedly connected to both ends of the rotating rod 302 are inserted into the limiting grooves 307 opened on the locking plate 306 fixed to the inner wall of the cabinet slot 2, and the front end of the locking plate 306 is inserted with the locking rod 309 and locked by the padlock 310 to prevent unauthorized personnel from privately switching the main body 201 of the reverse switch.
[0027] When it is necessary to open the protective cap 304 to switch the main body 201 of the reverse switch, first, multiple staff members holding keys are present and open the padlocks 310 at both ends of a single group simultaneously, remove the padlocks 310 from one end of the locking rod 309 and pull them out from the inside of the slot 308 to release the locking of the locking arms 305. At this time, by dialing a single protective cap 304 outwards, the rotating rod 302 is driven to rotate by the connecting arm 303, and the multiple protective caps 304 of a single group are rotated and opened simultaneously. At this time, the main body 201 of the reverse switch can be rotated and adjusted group by group. This device is convenient for opening the protective cap 304 to switch the main body 201 of the reverse switch.
