Technical Field
The invention relates to the technical field of display cabinets, in particular to a display cabinet capable of controlling the position of a night curtain by utilizing magnetic force and a using method.
Background
The display cabinet is a display platform which is provided for commodity display and has a protection function. The color may be selected according to the shop finish. The display cabinet has the advantages of firm structure, easy disassembly and assembly and convenient transportation.
Magnetic force is the force of a magnetic field on a magnet and current placed therein. Magnetic force is the propagation of an electromagnetic field, the speed of which is the speed of light, and the speed of the action of the magnetic force is also the speed of light. The property of an object that can attract iron, cobalt, nickel, etc. is called magnetism. Since magnetism refers to a property of a magnet that attracts paramagnetic substances, it is determined by the properties of the magnet itself. Magnetic force is one of the interaction forces, and the absence of a magnetic force from a magnet itself is a result of the interaction between two magnets, which can be expressed as a repulsive force and an attractive force. Therefore, it can be said that the magnetic force of the two poles of the magnet is strongest ", but it cannot be said that the magnetic force of the two poles of the magnet is maximum". When the property of a magnet is said, it must be said that it is magnetic, and when the interaction between magnets is said, it should be said that it is magnetic.
Night curtains (also known as night curtains, wind curtains, night covers) are an accessory to commercial clothes closets for the sale of food.
