A cabinet resistant to high and low frequency impact

Abstract

The invention discloses a high and low frequency impact resistance cabinet. The cabinet comprises an outer frame and an inner frame arranged in the outer frame, wherein a cabinet plate is wrapped on the exterior of the outer frame, and a shock absorber is arranged at the contacting position of the outer frame and the ground and / or the wall; and the inner frame is fixed in the outer frame through the shock absorbers. The cabinet provided by the invention is divided into the outer frame and the inner frame which are independent, the inner frame is connected with the outer frame through the shock absorbers, the outer frame and a mount point are also connected through the shock absorbers, and the inner and outer shock absorbers can both play the role of vibration damping and shock resistant as well as shock prevention; the shock absorbers arranged the outer frame and the mount point can isolate the low-frequency shock wave, the shock absorbers arranged between the outer frame and the inner frame can isolate the high-frequency shock wave, and the vibration isolation efficiency of the whole cabinet can achieve more than 80%; and the cabinet provided by the invention has the advantages that the whole is simple, the weight is light, and the processing difficulty is low.

Description

technical field [0001] The invention relates to an instrument installation cabinet, in particular to an impact-resistant cabinet with double-layer vibration isolation suitable for ships. Background technique [0002] In the prior art, the cabinets on ships are generally provided with shock isolation devices, that is, shock absorbers are provided between the cabinets and the installation location to achieve the purpose of shock isolation. This single-layer vibration isolation technology cannot solve the problem of high and low frequency vibration in the shock at the same time. In the prior art, it often only chooses to solve the shock and vibration of the high-frequency or low-frequency part, regardless of the other part. The efficiency of the cabinets with shock isolation in the frequency band is relatively low, and the efficiency of shock isolation is generally around 60%. [0003] In addition, the frame of the cabinet with single-layer vibration isolation technology is mo...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing cabinets cannot resist high and low frequencies at the same time, the present invention provides an impact-resistant cabinet with double-layer partitions. Frame, the outside of the outer frame is covered with cabinet panels, and it is characterized in that a shock absorber is provided at the position where the outer frame contacts the ground and / or the wall, and the inner frame is fixed in the outer frame by the shock absorber
