[0024] A control button is disposed on the upper front side of the cabinet door 2, and the position of the protective cover 33 corresponds to the control button, so that the protective cover 33 can shield the control button.

[0025] See also Figure 5 The utility model provides a high-voltage switch cabinet that can prevent misoperation. The fixing assembly 34 includes a sliding rod 341, a stabilizing block 342, a fixing block 343, a connecting rod 344, a pressing sleeve 345, a first spring 346 and a second spring 347. Two groups of sliding rods 341 are arranged at the middle end of the slide 32, and the sliding rods 341 are slidably matched with the slide 32. The tops of the two groups of sliding rods 341 are integrally formed with contact balls, and the surface of the contact balls is smooth. Two groups of stabilizing blocks 342 are embedded on both sides of the slide 32, and the stabilizing blocks 342 are slidably matched with the slide 32. The inner sides of the four groups of stabilizing blocks 342 are all arranged with inclined surfaces, and the tops of the sliding rods 341 are integrally formed with contact balls, and the surface of the contact balls is smooth. The contact ball contacts the inclined surface on the inner side of the stabilizing block 342, and the sliding rod 341 can push the stabilizing block 342 through the contact ball. The middle part of the top of the slide table 32 is bolted with a fixing block 343, and a connecting rod 344 is integrally formed at the top of the upper sliding rod 341, and the connecting rod 344 slides with the fixing block 343 to make the sliding of the sliding rod 341 more stable.

[0027] Here’s how it works:

[0028] The staff first connects the wires to the high-voltage switch cabinet body 1, and then the circuit control can be achieved through the control button at the front end of the cabinet door 2.

[0029] When there is no need to operate the switch cabinet, the staff can push the pressing sleeve 345 upwards, and the pressing sleeve 345 will drive the two sets of sliding rods 341 to move upwards. The sliding rods 341 will compress the first spring 346 and the second spring 346 during the movement, and the upper sliding rod 341 can move within the fixed block 343 through the connecting rod 344 to provide a guide for the movement of the sliding rod 341. During the upward movement of the sliding rod 341, the contact ball at the upper end thereof will separate upwards from the inner inclined surface of the stabilizing block 342, so that the stabilizing block 343 is 42 is no longer limited. At this time, the staff can push the slide 32 upward to make the slide 32 move upward in the slide groove 31. The slide 32 will drive the protective cover 33 to cover the control button to prevent accidental touch. Then the pressing sleeve 345 can be relaxed. The elastic force of the first spring 346 and the second spring 347 will make the two sets of sliding rods 341 reset downward, and the contact ball on the sliding rod 341 will push the stabilizing block 342 to expand to both sides, so that the stabilizing block 342 is against the inner side of the slide groove 31, so as to realize the positioning of the protective cover 33.
