The anti-shake unit 22 includes a connecting column 221 vertically mounted on the connecting plate 21, a tube body 222 colinear with the vertical center line of the connecting column 221 is mounted at the lower end of the connecting frame 23, the end of the connecting column 221 farther from the connecting plate 21 can move through the tube body 222, a gasket 223 is screwed on the outer side of the end of the connecting column 221 close to the connecting plate 21, and a spiral beryllium copper wire 224 is hooped on the outer side of the tube body 222, and the radius of the gasket 223 is larger than the spiral The radius of the outer circle of the beryllium copper wire 224; the anti-shake unit 24 includes an energy dissipator 241, the end of the energy dissipator 241 farther from the connecting plate 21 is movably connected to the connecting frame 23 via a track 242, the end of the energy dissipator 241 farther from the connecting frame 23 is connected to the connecting plate 21, and the energy dissipator 243 is installed opposite to the side of the energy dissipator 241; the outer side of the connecting column 221 close to the connecting plate 21 is provided with a lead screw 225, and the gasket 223 is The ring-shaped structure has a first thread opening for matching with the lead screw 225 reserved on the inner circumference of the gasket 223, the gasket 223 is threadedly connected to the lead screw 225, and the lead screw 225 is also threadedly connected to an inner thread opening tube 226 that is tightly attached to the gasket 223; one end of the energy dissipator 241 is screwed to the connecting plate 21, and the other end of the energy dissipator 241 is screwed to the movable column 244, the track 242 is installed on the connecting frame 23, and the movable column 244 passes through and is movably installed in the track 242.

[0038] When the switch cabinet body 1 is vibrated, the connecting plate 21 drives the connecting column 221 to move back and forth in the tube body 222. When the gasket 223 and the spiral beryllium copper wire 224 are pressed against each other, the spiral beryllium copper wire 224 is shortened, thereby achieving the purpose of reducing the vibration; the position of the gasket 223 can also be changed on the screw 225, and then the position of the gasket 223 is stopped through the inner thread tube 226, thereby changing the span between the spiral beryllium copper wire 224 and the gasket 223, thereby achieving the purpose of reducing various degrees of vibration.

[0039] A long strip opening 2421 is transversely arranged on the track 242, and a movable column 244 is transversely movably arranged in the long strip opening 2421. A pair of jitter reduction units 25 are mirror-arranged in the long strip opening 2421. The jitter reduction units 25 are located on both sides of the movable column 244. The peripheral surface of the movable column 244 and the jitter reduction unit 25 are closely attached to each other. The jitter reduction unit 25 includes a first attachment block 251 and a second attachment block 252. The first attachment block 251 and the second attachment block 252 are respectively arranged on the long strip opening 24 On the two vertical walls inside 21, the first attachment block 251 is assembled at the upper end inside the long strip opening 2421 via a plurality of first tensioning screws 2511, and the second attachment block 252 is assembled at the lower end inside the long strip opening 2421 via a plurality of second tensioning screws 2521; an elastic block 253 is arranged between the first attachment block 251 and the second attachment block 252, and the arched portion of the elastic block 253 is located at one end close to the movable column 244, and the outer surface of the movable column 244 and the arched portion of the elastic block 253 are in close contact with each other.

[0040] When vibration occurs, the connecting plate 21 exerts pressure on a pair of anti-vibration units 24. At this moment, the end of the energy absorber 241 away from the connecting frame 23 rotates on the connecting plate 21, and the end of the energy absorber 241 farther from the connecting plate 21 moves in the track 242, and the movable column 244 moves in the long strip opening 2421. The movable column 244 exerts pressure on a pair of vibration reduction units 25 in the long strip opening 2421, and the arched parts of the movable column 244 and the elastic block 253 are tightly attached to each other, allowing the elastic block 253 to change its shape, thereby achieving the purpose of reducing vibration.

[0041] The upper end of the track 242 is reserved with a plurality of second thread openings for cooperating with the first tensioning screw 2511, and the lower end of the track 242 is reserved with a plurality of third thread openings for cooperating with the second tensioning screw 2521, so that the first attachment block 251 and the second attachment block 252 can be assembled at various positions in the long strip 2421 via the first tensioning screw 2511 and the second tensioning screw 2521 respectively, and the distance between the first attachment block 251 and the second attachment block 252 after assembly can be changed, so that the distance between a pair of jitter reduction units 25 can be changed, and then the size of the area where the movable column 244 changes in the long strip 2421 can be changed.

[0042] A number of protrusions 2531 are arranged at even intervals on the arch surface of the outer side of the elastic block 253. When the movable column 244 is in close contact with the arched portion of the elastic block 253 in the long strip opening 2421, the surface of the movable column 244 and the protrusions 2531 are pressed tightly, which can strengthen the obstruction between the surface of the movable column 244 and the arched portion of the elastic block 253, thereby avoiding or reducing the movement of the movable column 244 and the arched portion of the elastic block 253 when they are in close contact.

[0043] When the anti-shake unit 22 is not needed, the position of the gasket 223 can be changed by rotating on the lead screw 225, so that the gasket 223 can be moved to the side farther away from the spiral beryllium copper wire 224; when the switch cabinet is shaken, the connecting plate 21 is away from the connecting frame 23, and the shaking of the switch cabinet can be reduced under the cooperation of a pair of anti-shake units 24; when the shaking is severe, the degree of squeezing of the pair of anti-shake units 24 by the connecting plate 21 becomes larger, and the distance between the connecting plate 21 and the connecting frame 23 is smaller. When the gasket 223 and the spiral beryllium copper wire 224 are in close contact, the shaking can be reduced under the cooperation of the spiral beryllium copper wire 224 and the pair of anti-shake units 24; the anti-shake unit 1 22 can be used to enhance the function of reducing shaking, and then prevent the anti-shake unit 2 24 from recovering slowly during shaking and reducing the function of reducing shaking.

[0044] Reference Figure 8 The energy dissipator 243 includes an energy dissipator body 2431, which is fixedly connected to the side of the energy dissipator 1 241. The energy dissipator body 2431 and the energy dissipator 1 241 are arranged opposite to each other, and the output end of the energy dissipator body 2431 is located at an end close to the output end of the energy dissipator 1 241; the compression block 2432 is arranged on the output end of the energy dissipator 1 241, and the upper wall of the compression block 2432 is opposite to the output end of the energy dissipator body 2431; the inner surface of the hoop 2433 is reserved with a fourth thread opening, and the outer surface of the output end of the energy dissipator body 2431 is reserved with an outer thread opening, the hoop 2433 is threadedly connected to the outer side of the output end of the energy dissipator body 2431, and the end of the hoop 2433 farther from the output end of the energy dissipator body 2431 is opposite to the upper wall of the compression block 2432.

[0045] When the switch cabinet body 1 is subjected to severe vibration, the output end of the energy absorber 241 moves in the outer tube of the energy absorber 241 to reduce the vibration, which can drive the compression block 2432 on the output end of the energy absorber 241 to move together. When the compression block 2432 moves to be in close contact with the hoop tube 2433, the compression block 2432 moves toward the side close to the hoop tube 2433, which can compress the output end of the energy absorber body 2431, and then the output end of the energy absorber body 2431 moves in the outer tube of the energy absorber body 2431 to reduce the vibration, thereby enhancing the purpose of reducing the vibration of the switch cabinet body 1. The distance between the hoop 2433 and the compression block 2432 can also be changed by rotating the outer side of the output end of the energy dissipator body 2431 as needed. When the distance between the hoop 2433 and the compression block 2432 becomes larger, the switch cabinet body 1 is subjected to severe vibration, and the compression block 2432 and the hoop 2433 can touch each other; when the distance between the hoop 2433 and the compression block 2432 becomes smaller, the switch cabinet body 1 is subjected to lighter vibration, and the compression block 2432 and the hoop 2433 can touch each other, and then according to the degree of vibration, it can be decided whether to use the energy dissipator 243 to help reduce the vibration.

[0046] The connection module 3 includes a connection block 31 fixedly connected to the side wall of the switch cabinet body 1, the connection block 31 is engaged with the connection frame 23, and sockets are reserved on the connection block 31 and the connection frame 23. The same plug rod 32 is inserted into the connection blocks 31 and the connection frame 23 on the left and right sides. The two ends of the plug rod 32 pass through the corresponding connection frame 23, and the ends of the plug rod 32 are reserved with a U-shaped opening 33. The two side walls of the U-shaped opening 33 are screwed with a rotating rod 34, and the rotating rod 34 is screwed with a rotating rod 34. The connecting block 35 is fixedly connected, and a torsion spring 36 is clamped on the outer surface of the rotating rod 34. The two ends of the torsion spring 36 are respectively fixedly connected to the side walls of the connecting block 35 and the side walls of the U-shaped opening 33. The end of the connecting block 35 extending out of the U-shaped opening 33 is fixedly connected to a limiting rod 37. The radius of the limiting rod 37 is smaller than the radius of the insertion rod 32, and the rotation radius of the limiting rod 37 is larger than the radius of the socket. With the cooperation of the torsion spring 36, in the natural state, the limiting rod 37 is always perpendicular to the insertion rod 32.

[0047] When in use, the connecting block 31 is stuck on the connecting frame 23, and the limit rod 37 is pulled to make the limit rod 37 flush with the insertion rod 32. At this time, the shape of the torsion spring 36 changes, and then the limit rod 37 and the insertion rod 32 are inserted into the corresponding sockets. When the ends of the insertion rod 32 completely pass through the sockets on both sides, the limit rod 37 is released, and with the cooperation of the torsion spring 36, the limit rod 37 is returned to its position, so that the switch cabinet body 1 and the protection module 2 are quickly assembled. When disassembly is required, only the limit rod 37 needs to be straightened to pull out the insertion rod 32, and the disassembly is very convenient.
