The invention discloses a high-efficiency shockproof low-voltage cabinet. The high-efficiency shockproof low-voltage cabinet comprises a cabinet body, a connection plate, an adjustment lead screw anda base, wherein the base comprises a first bottom plate, a second bottom plate is arranged right above the first bottom plate, two ends of the second bottom plate vertically face upward, wheel shaftsare fixedly arranged at positions, near to one side of the second bottom plate, of two ends of the first bottom plate, and a roller is movably connected with one end, far away from the first bottom plate, of each wheel shaft. By matching of a first installation frame, a second installation frame, a first magnetic block, a second magnetic block, a support rod, a support plate and a telescopic spring, the vibration generated by a power cabinet during running can be greatly reduced, a shockproof effect is good, stable running of the power cabinet is favorably maintained, the integral service lifetime of the power cabinet is prolonged, heat is absorbed by cooling fins, blades are driven to rotate so as to rapidly cool the cooling fins by a fan, and heat dissipation in the cabinet is further accelerated.
