[0002] In recent years, museums across the country have successively carried out preventive protection work on their collections of cultural relics. By configuring cabinets, shelves, bags and boxes, and seismic retrofit upgrades and other measures, the storage conditions and seismic and shock-absorbing capabilities of cultural relics in warehouses have been effectively improved.

[0003] However, the anti-vibration and shock-absorbing capabilities of cultural relics on display are insufficient, and there is still a phenomenon of cultural relics being damaged by vibration. The main reason is that the existing shock-absorbing measures are mainly aimed at natural disasters such as earthquakes, and there is a lack of effective protection measures against human-induced vibrations.

[0004] Human-induced vibration is one of the most significant long-term environmental vibrations faced by museum collections, especially for high-level museums with large flow of people and complex and random vibrations, which can easily cause vertical vibrations of the floor slabs, and then bring about forced vibrations of the museum collections. Long-term environmental vibrations can cause fatigue problems in the materials of the museum collections, which in turn cause damage and deterioration of the materials, and may even lead to the risk of fracture, causing immeasurable losses. Summary of the invention

[0008] Furthermore, the panel is connected to the column via a connecting piece.

[0009] Furthermore, the height of the annular beam gradually increases in a direction approaching the display cabinet.
