Description

Technical Field

[0001] The utility model belongs to the technical field of magnet installation, in particular to a quick-disassembly magnet. Background Art

[0002] Magnets are processed from natural ferromagnetic ores. Their main components are iron, cobalt, nickel, etc. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. Due to their special physical properties, they are widely used in many fields. During the use of magnets, they often need to be installed through mounting parts.

[0003] In the prior art, Chinese patent announcement number CN220020781U discloses a magnet sheet that is easy to fix and disassemble, which relates to the field of magnet sheet technology, including: a magnet sheet body and a magnetic attraction block, a mounting block is installed on the outside of the magnet sheet body, the magnetic attraction block is arranged inside the mounting block, and a connecting block is connected to one side of the magnetic attraction block. The beneficial effect of the magnet sheet that is easy to fix and disassemble is: when in use, the magnet sheet body can be docked into the mounting block, and then the connecting block is driven to reset by the movable spring, and the magnetic attraction block on one side of the connecting block is pushed to adsorb with the magnet sheet body. At this time, the magnet sheet body can be fixed in the mounting block by the magnetic attraction block, so that the magnet sheet body can be fixed quickly and conveniently. On the contrary, the magnetic attraction block is separated from the magnet sheet body, and the magnet sheet body can be removed from the mounting block, which is convenient for fixing and disassembling the magnet sheet body. This is the use feature of the magnet sheet that is easy to fix and disassemble.

[0004] However, the magnet sheet provided in the above technical solution, which is easy to fix and disassemble, still has many disadvantages in actual use. For example, the magnet sheet is adsorbed into the groove of the mounting part by the magnetic force of multiple magnet blocks. Although it can achieve the purpose of quick fixation, after use, due to the quick suction force of the magnet, the magnet blocks on the mounting part need to be removed one by one when disassembling the magnet sheet, which makes it very troublesome to disassemble the magnet sheet and leads to poor practicality.
