Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a fastener with a protective structure. Background Art

[0002] Fasteners are also called standard parts in the market. They are mechanical components that can mechanically fix or bond two or more components together. They are characterized by a wide variety of specifications, different performances and uses, and a large demand.

[0003] During the use of fasteners, the hexagonal head of the fastener will be exposed to the outside and will be eroded by rain and air for a long time, causing rust on the hexagonal head. As the rust peels off layer by layer, the hexagonal head will slip when the tool is used to twist it, which is not conducive to the removal of the fastener. In addition, when the fastener is installed, it is necessary to punch holes and plug the tube. When the plug tube is completely immersed in the fixed hole, there is a certain gap between the fixed hole and the hexagonal head. If rainwater enters the fixed hole through the gap, it will cause rust on the screw part of the fastener, reducing the service life of the screw. Utility Model Content

Under the elastic force of the spring piece, the hook enters the inner limiting groove on the inner wall of the hexagonal fixing groove, and the hexagonal protective cover is fixed to the outer surface of the hexagonal head to seal the hexagonal head to prevent the hexagonal head from being corroded by excessive rainwater and air.
