[0028] The buffer part 2 includes: a buffer plate 211, which is rotatably connected to one side of the protection box 1 through a shaft; a buffer slot block 212, which is fixedly connected to one side of the protection box 1; and a slide rail 213, which is fixedly connected to the bottom inner wall of the protection box 1.

[0029] A fixing rod is fixedly connected to one side of the buffer plate 211 , and the fixing rod is matched with the buffer slot block 212 . Sliding holes are opened on both sides of the slide rail 213 and are equidistantly arranged.

[0030] The slide rail 213 is internally slidably connected to a slider 214, and limit holes are provided on both sides of the slider 214. A connecting rod 215 is provided between the slider 214 and the buffer plate 211. One end of the connecting rod 215 is rotatably connected to the top of the slider 214 through a base, and the other end is rotatably connected to the inner wall of the buffer plate 211 through a base.

[0031] A spring 217 is fixedly connected to one side of the slide rail 213, one end of the spring 217 is fixedly connected to a damping rod 216, one end of the damping rod 216 passes through the sliding hole and is adapted to the limiting hole, a damper 218 is fixedly connected to the inside of the slide rail 213, and a spring 219 is sleeved on the outer wall of the damper 218.

[0032] Furthermore, in this embodiment, when a heavy object hits the protective box 1, the buffer plate 211 rotates around the axis, and the protective box 1 is initially buffered with the assistance of the fixed rod and the buffer slot block 212. When the buffer plate 211 rotates, the slider 214 slides along the track of the slide rail 213 under the action of the connecting rod 215, so that the slider 214 is damped with the assistance of the damping rod 216 and the spring 1 217. Subsequently, when the slider 214 slides to one end of the damper 218, the buffer plate 211 is subjected to multiple buffering effects under the action of the damper 218 and the spring 2 219.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of a variable frequency control cabinet with a protective structure provided by the utility model is as follows: Figure 1-5 As shown: the fixed part 3 includes: a slide 311, which is fixedly connected to the bottom inner wall of the protection box 1; and a fixed plate 312, which is fixedly connected to the bottom inner wall of the protection box 1.

[0035] The top of the slideway 311 is slidably connected to a controller body 313 , one side of the controller body 313 is fixedly connected to a fixed block 314 , and one side of the fixed plate 312 is rotatably connected to a block 315 via a shaft.

[0036] The clamping block 315 is matched with the fixed clamping block 314 . The clamping block 315 and the fixed plate 312 are provided with a spring three 316 . One end of the spring three 316 is fixedly connected to one side of the clamping block 315 , and the other end is fixedly connected to one side of the fixed plate 312 .

[0037] Furthermore, in this embodiment, by pushing the controller body 313, the controller body 313 slides along the track of the slide 311, so that the fixed block 314 squeezes the block 315, and the spring three 316 contracts. As the controller body 313 is continuously pushed, when the fixed block 314 no longer squeezes the block 315, under the action of the spring three 316, the block 315 rebounds to fix the controller body 313.

[0038] When in use, first, when a heavy object hits the protection box 1, the buffer plate 211 rotates around the axis, and the protection box 1 is initially buffered with the help of the fixed rod and the buffer slot block 212. When the buffer plate 211 rotates, the slider 214 slides along the track of the slide rail 213 under the action of the connecting rod 215, so that the slider 214 is damped with the help of the damping rod 216 and the spring 217. Subsequently, when the slider 214 slides to one end of the damper 218, the damper 218 and the spring 217 are connected to each other. Under the action of the second 219, the buffer plate 211 has a multiple buffering effect; secondly, when the controller body 313 is pushed, the controller body 313 slides along the track of the slide 311, so that the fixed block 314 squeezes the block 315, and the spring three 316 contracts. As the controller body 313 is continuously pushed, when the fixed block 314 no longer squeezes the block 315, under the action of the spring three 316, the block 315 rebounds to have the effect of locking and fixing the controller body 313.
