Description

Technical Field

[0001] The utility model relates to the technical field of socket magnets, and particularly relates to a polyurethane strong magnet. Background Art

[0002] Traditional socket magnets are assembled from neodymium iron boron strong magnets, metal shells, copper rings, etc. The metal shells are processed by numerical control lathes, and most of the materials are made of stainless steel and carbon steel. This structure is simple and the cost is low. The advantages of socket magnets are that they are easy to install and use, and provide a certain degree of protection for the magnets. However, in some cases, due to the existence of the base, the design and use of the magnets may be restricted to a certain extent. Especially in applications that require high flexibility, if a strong impact is applied or the adsorption surfaces are pressed tightly against each other, the magnet cover may fall off. In addition, if the magnet surface directly bears a strong impact, the magnet may be damaged. Therefore, when using socket magnets, these potential risks need to be considered and corresponding preventive measures need to be taken. Once the metal shell of the socket magnet falls off during the process, it means that the entire magnet component needs to be repurchased, which is both time-consuming and costly.

[0003] In view of the above-mentioned potential safety hazards, a polyurethane strong magnet is proposed. Content of the Utility Model
