Description

Technical Field

[0001] The utility model relates to the field of magnetic suspension, in particular to a magnetic suspension display device. Background Art

[0002] Magnetic levitation technology is a technology that uses magnetic force to overcome gravity to suspend an object. This technology mainly uses the principle that like poles of a magnetic field repel each other. By controlling the size and direction of the repulsive force, the repulsive force and gravity are equal, so that the upper magnet can be suspended in the air. Magnetic levitation ornaments are a very special kind of decoration. Magnetic levitation ornaments rely on the spatial magnetic field generated by magnetic force to make the suspended ornaments rotate and suspend on the bracket. This technology gives the ornaments a unique dynamic and visual effect. Compared with traditional ornaments that do not use magnetic levitation technology and are usually just statically placed in a certain position, magnetic levitation ornaments present a dynamic beauty and high-tech sense through their unique suspension and rotation effects. This visual effect is more eye-catching than traditional ornaments and can add a unique atmosphere to the space. Magnetic levitation ornaments are suitable for various modern, simple or technological scenes, such as offices, homes, exhibition halls, etc.

[0003] The magnetic suspension pendulum is mainly composed of two parts: the bracket and the suspended object. A set of two magnets is installed on the bracket, and a set of one magnet is installed on the suspended object, thus forming a tiny magnetic suspension device. When the magnets on the bracket generate a magnetic field, the magnets on the suspended object will also generate an anti-magnetic field. When the force formed by the two magnetic fields is greater than the gravity, the magnetic suspension phenomenon will occur, achieving the suspension effect.

[0004] The exhibits suspended by existing magnetic levitation ornaments are usually fixed, and different products cannot be replaced for display. The functionality is insufficient, and a single product lacks freshness after being displayed for a long time. Utility Model Content
