[0021] See also Figure 1-Figure 4 In order to solve the problem that it is difficult to ensure the safety of the switch cabinet in a high-intensity vibration environment, which easily causes damage to the components in the switch cabinet and insufficient practicality, the following preferred technical solutions are provided:

[0022] A seismic structure for a moisture-proof constant temperature low-voltage switch cabinet, comprising a moisture-proof constant temperature switch cabinet 1, and a seismic assembly 2 installed at the lower end of the moisture-proof constant temperature switch cabinet 1, the seismic assembly 2 comprising a support block 21, and a pressing block body 22, the lower end of the support block 21 is fixedly connected to a rotating shaft body 23, the inner wall of the rotating shaft body 23 is connected to a first oblique rod 24 and a second oblique rod 25, the lower end of the first oblique rod 24 is connected to a first slider 26, the lower end of the second oblique rod 25 is connected to a second slider 27, the first slider 26 and the second slider 27 are both slidably connected to the bottom plate of the cavity of the support block 21, the end of the first slider 26 close to the second slider 27 is fixedly connected to the outer rod 28, the end of the second slider 27 close to the first slider 26 is fixedly connected to the inner rod 29, the inner rod 29 is slidably connected to the inner wall of the outer rod 28, the outer wall of the inner rod 29 is sleeved with a shock-absorbing spring 210, one end of the shock-absorbing spring 210 is fixedly connected to the second slider 27, and the other end thereof is fixedly connected to the outer rod 28.

[0023] The pressing block body 22 is fixedly connected to the lower wall of the moisture-proof thermostatic switch cabinet 1 , and the pressing block body 22 is slidably connected to the inner wall of the support block 21 . The first oblique rod 24 and the second oblique rod 25 are symmetrically distributed about the center of the rotating shaft body 23 .

[0024] A mounting block 211 is provided at the opposite end between the first slider 26 and the second slider 27, and a buffer cavity 212 is opened inside the mounting block 211. A buffer block 213 is slidably connected to the inner wall of the buffer cavity 212, and an elastic ball 214 is installed on the inner wall of the buffer block 213. The buffer block 213 and the elastic ball 214 are both components made of rubber material, and the interior of the elastic ball 214 is a hollow structure. An elastic element 215 is fixedly connected to the interior of the elastic ball 214. Two groups of elastic elements 215 are provided, and the two groups of elastic elements 215 are distributed perpendicular to each other. The buffer block 213 is truncated cone-shaped, and the maximum diameter of the buffer block 213 is greater than the inner diameter of the buffer cavity 212.

[0025] Specifically, when the moisture-proof thermostatic switch cabinet 1 vibrates, the vibration force will drive the pressure block body 22 to move up and down toward the inner wall of the support block 21, so that under the drive of the pressure block body 22, the first inclined rod 24 and the second inclined rod 25 will respectively pull up or press down the first slider 26 and the second slider 27, thereby driving the inner rod 29 to move on the inner wall of the outer rod 28, thereby driving the shock-absorbing spring 210 to tighten or press, and the vibration force is offset by the reaction force of the shock-absorbing spring 210, so as to achieve the purpose of efficient shock absorption, and solve the problem that it is difficult to ensure the safety of the switch cabinet in a high-intensity vibration environment, thereby easily causing damage to components in the switch cabinet and insufficient practicality.

[0026] When the pressure block body 22 moves toward the inner wall of the support block 21, the buffer block 213 will move on the inner wall of the buffer cavity 212. The inner wall of the buffer cavity 212 will squeeze its outer wall as the buffer block 213 moves downward. At this time, the elastic ball 214 will be compressed to squeeze the elastic element 215. The friction force of the buffer block 213 on the inner wall of the buffer cavity 212 will be increased through the action force of the elastic element 215. When the vibration force decreases, the buffer block 213 will stop the rebound force of the shock-absorbing spring 210 in time, thereby ensuring the shock-absorbing effect.
