Magnetic suspension plate-shaped rigid damping sound insulation cushion

Abstract

The invention belongs to the technical field of magnetic suspension application and relates to a magnetic suspension plate-shaped rigid damping sound insulation cushion. A damping sound insulation cushion body comprises magnets, four supporting jackets and a nonmetal plate-shaped rigid cushion. The magnets include a lower high-magnetism magnet and an upper high-magnetism magnet. The lower high-magnetism magnet is welded to the lower portions of the supporting jackets. The upper high-magnetism magnet is arranged on the upper portions of the supporting jackets in a sleeving manner and is fixedlyconnected with the nonmetal plate-shaped rigid cushion. The opposite polarities of the upper high-magnetism magnet and the lower high-magnetism magnet are the same. The nonmetal plate-shaped rigid cushion is movably connected with the supporting jackets. The magnetic suspension plate-shaped rigid damping sound insulation cushion has the beneficial effects of being low in sound source conductivity, good in shock insulation effect and electrical insulation performance, fearless in puncturing decompression and the like and also has the beneficial effects of being wide in service environment range, free of maintaining and the like. The magnetic suspension plate-shaped rigid damping sound insulation cushion is suitable for being put on a plane at any angle and direction to be used and can effectively resist a vibration sound source from being downwards transmitted in the direction perpendicular to the direction of the plate-shaped rigid damping sound insulation direction, and for example,related seismic source type instrument equipment is put or fixed to the magnetic suspension plate-shaped rigid damping sound insulation cushion, and the magnetic suspension plate-shaped rigid dampingsound insulation cushion can also be used when damping and sound insulation are needed in a house.

Description

technical field [0001] The invention belongs to the technical field of magnetic suspension applications, and relates to a magnetic suspension plate-shaped rigid shock-absorbing and sound-insulating pad. Background technique [0002] Existing shock-absorbing and sound-insulating pads are generally made of flexible materials. If a plate-shaped rigid material is required as a shock-absorbing and sound-insulating pad, the prior art usually uses steel springs or gas springs to achieve this. So far, there is no such A device using the principle of magnetic levitation to meet the needs of plate-shaped rigid shock-absorbing and sound-insulating pads. The existing plate-shaped rigid shock-absorbing and sound-insulating pads generally have shortcomings such as insufficient sound source conductivity and insufficient shock isolation effect. In addition, the plate-shaped rigid sound insulation pad with a spring structure has problems such as poor electrical insulation and pressure punctu...
