Waterproof strong magnet

Abstract

The invention discloses a waterproof strong magnet which comprises a mounting base and a protective cover, a body is fixedly connected to the bottom of the mounting base, grooves are formed in the twosides of the top of the protective cover, sealing rings are arranged in inner cavities of the grooves, sliding grooves are formed in the two sides of the bottom of the mounting base, and sliding blocks are slidably connected to inner cavities of the sliding grooves; fixing blocks are fixedly connected to the two sides of the bottom of the mounting base, supporting rods are fixedly connected to the opposite sides of the fixing blocks, and movable rods are movably connected to the surfaces of the sides, away from the fixing blocks, of the supporting rods. Through cooperative use of the mountingbase, the protective cover, the body, the groove, the sealing ring, the sliding groove, the sliding block, a fixed block, a supporting rod, a movable rod, a clamping block, a clamping groove, a spring and a waterproof layer, the problems that an existing strong magnet is poor in waterproof effect in use, degaussing is caused due to difference of environment temperature, use is inconvenient for auser, and use is inconvenient are solved. The practicability of the strong magnet is reduced.

Description

technical field [0001] The invention relates to the technical field of strong magnets, in particular to a waterproof strong magnet. Background technique [0002] Strong magnets are also rare earth strong magnets, that is, NdFeB strong magnets. NdFeB has the characteristics of small size, light weight and strong magnetism. It is the magnet with the best performance and price ratio so far. NdFeB is the third generation of rare earth Permanent magnet materials have a high performance-price ratio. They are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries. Especially with the development of knowledge economy represented by information technology, rare earth permanent magnet NdFe Functional materials such as the boron industry continue to bring new uses, which brings a broader market prospect for the NdFeB industry. However, the existing strong magnets are not waterproof when used. phenomenon, it is inconvenient for users to use,...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a waterproof strong magnet, which has the advantage of good waterproof effect, and solves the problem that the existing strong magnet has poor waterproof effect when used, and the phenomenon of demagnetization caused by differences in ambient temperature is inconvenient for users. The use of strong magnets reduces the practicality of the problem
