Embodiment Construction

[0031] Such as figure 1 , 3 As shown, the high and low frequency impact resistant cabinet of the present invention includes an outer frame 1 and an inner frame 2 installed inside the outer frame. The outer frame 1 is covered with a cabinet board 3, and the outer frame 1 is in contact with the ground and / or wall. A shock absorber 4 is provided there, and the inner frame 2 is fixed in the outer frame 1 through the shock absorber 4. The outer frame 1 contacts the installation point through the shock absorber 4, changing the hard contact between the original cabinet and the installation point to elastic contact, so that the low-frequency impact of the cabinet is reduced, and the inner frame 2 and the outer frame 1 are also elastic The shock absorber 4 is connected, so that the high-frequency impact of the inner frame 2 is further reduced, and the safety of various electronic devices installed in the inner frame is guaranteed to the greatest extent. The entire cabinet of the present...

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 anti-shock cabinet with double-layer vibration isolation suitable for ships. Background technique [0002] In the prior art, cabinets on ships are generally equipped with shock isolation devices, that is, a shock absorber is set between the cabinet and the installation position to achieve the purpose of shock isolation. This single-layer vibration isolation technology cannot solve the high- and low-frequency vibration problems in the impact at the same time. In the prior art, it is often only selected to solve the impact and vibration of the high-frequency or low-frequency part, regardless of the other part, so that it is only for a certain part. The efficiency of the cabinet with frequency band isolation is relatively low, and the isolation efficiency is generally about 60%. [0003] In addition, the frame of the single-layer vibration isolation technology cabinet is mostly mad...
