Description

Technical Field

[0001] The utility model relates to the technical field of electrical component protection, in particular to a box waterproof sealing structure. Background Art

[0002] With the rapid development of intelligent machines, the operating environments of precision instruments such as electrical components are becoming increasingly complex, making traditional instrument protection methods no longer sufficient. Traditional instrument enclosures consist of a housing, electrical components, and a lid. Sealing rings or gaskets are used in environments subject to heavy dust and oil pollution, but these seals are only a single layer. Their effectiveness is generally limited, meeting only short-term requirements. However, over time, dust and oil will continue to enter and damage the electrical components. However, these protective measures are clearly ineffective in environments subject to water spray or severe dust, rendering them inadequate for normal operation. In the field of ore color sorting, where dust is high on-site, materials such as quartz and pebbles must be sprayed with water before sorting to restore the ore to its original nature before entering the sorting machine, resulting in the desired finished ore material. This necessitates higher standards for enclosure protection to better protect the electrical components and precision instruments within. Utility Model Content
