A pendulum three-dimensional shock-isolation showcase for anti-seismic protection of floating objects

Abstract

The invention discloses a swing type three-dimensional shock isolating showcase for shock-resisting protection of a freestanding object and belongs to the field of exhibition of displayed objects. Theswing type three-dimensional shock isolating showcase for shock-resisting protection of the freestanding object aims to overcome the defect that an existing three-dimensional shock isolating device is high in conduction ratio. The swing type three-dimensional shock isolating showcase for shock-resisting protection of the freestanding object comprises an upper top plate, a lower base plate and anenclosure located between the upper top plate and the lower base plate. A swing type object holding device is arranged between the upper top plate and the lower base plate and comprises axial stretching structures, a holding platform, axial damping structures and a horizontal stabilizing mechanism. The axial stretching structures are located between the upper top plate and the holding platform and arranged at the four corners of the holding platform in array. The axial damping structures are located between the holding platform and the lower bottom plate, and each axial damping structure is coaxial with the corresponding axial stretching structure. The horizontal stabilizing mechanism is located between the holding platform and the lower base plate and located in a area defined by the four axial damping structures. During shock, the horizontal stabilizing mechanism drives the holding platform to synchronously generate horizontal swing. According to the swing type three-dimensional shock isolating showcase for shock-resisting protection of the freestanding object, the shock isolation principle is easy and clear, shock isolation parameters are convenient to adjust, and start is sensitive.

Description

Technical field: [0001] The invention belongs to the technical field of exhibits display, and is particularly suitable for the display of floating objects such as cultural relics, and specifically relates to a pendulum type three-dimensional seismic isolation showcase used for seismic protection of floating objects. Background technique: [0002] Cultural relics are relics and relics of historical, artistic and scientific value left by human beings in social activities. They are an important part of the world's cultural heritage. They have extremely important cultural, historical and cultural relic values ​​and are of great significance to protection. [0003] When categorizing cultural relics, they can be divided into immovable cultural relics and movable cultural relics. The movable cultural relics can be moved at will according to the needs of storage, research, and display, and the location can be changed. This not only has no effect on its own value, but also Better play the r...

Problems solved by technology

[0004] Although the Chinese patent CN200710099753.2 discloses a friction-spring three-dimensional seismic isolation bearing, which includes two parts, a horizontal vibration isolation device and a vertical vibration isolation device, the overall shape of the bearing is cylindrical, and the horizontal direction of the bearing adopts flat plate sliding The vibration isolation device is equipped with a reset and limit device in the horizontal direction, and a spring vibration isolation device is used in the vertical direction. However, the structure of the device is complicated, the volume is large, and the conduction ratio is high, so it is not suitable for the protection of cultural relics.
