Liquid-bag type shock isolator for shock isolation of cultural relics and showcases

Abstract

The invention discloses a liquid-bag type shock isolator for shock isolation of cultural relics and showcases and belongs to the field of cultural relic shock isolation. The liquid-bag type shock isolator comprises a top steel plate, a rubber bag, a bottom steel plate, an oil filling hole, silicon oil filled into the rubber bag, a groove and a raised plate. The top steel plate and the bottom steel plate are connected through the rubber bag which is filled with the silicon oil. The silicon oil is filled through the oil filling hole. The groove is formed in the top steel plate, and the raised plate is arranged on the bottom steel plate. The size of the rubber bag is equal to those of the groove and the raised plate. Different application requirements can be met by regulating shape and size of the top steel plate and the bottom steel plate, the thickness of the rubber bag and the viscosity of the silicon oil. The liquid-bag shock isolator is simple in structure, small in thickness and easy to be standardized and has both horizontal shock isolation capacity and vertical shock isolation capacity.

Description

Technical field: [0001] The invention relates to a shock isolator used for shock isolation of cultural relics and display cabinets, in particular to a liquid bag type shock isolator for reducing earthquake damage to movable cultural relics. Background technique: [0002] The protection of movable cultural relics has always been a special concern of the country. In recent years, with the rapid development of social economy, the State Administration of Cultural Heritage has paid more and more attention to the protection and restoration of movable cultural relics. In 2011, it added special funds for the protection of movable cultural relics for the first time, and this marked the beginning of the protection of movable cultural relics in my country. A new chapter of work. The most important item in the protection of cultural relics is earthquake protection. The earthquake damage of a large number of cultural relics shows that the phenomenon of collision and damage between displ...

AI Technical Summary

Problems solved by technology

Horizontal vibration isolation devices mainly include roller type, roller type, ball type, slider type, etc. The existing problems mainly include complex structure, which is not suitable for large cultural relics, and when the stroke of the sliding device part is too large, it will fly out Concave surface, etc.

Vertical vibration isolation devices mainly include parallelogram chain rod mechanism, negative stiffness mechanism, air spring, spring and guide rod, constant force spring, torsion spring and other vibration isolation devices. longitudinal bending
