Rust-proof nut

Abstract

The invention discloses a rust-proof nut. When the nut is in a working state, a screw rod or other external thread structures are locked by rotating the nut, and the nut abuts against a fixing structure through an annular gasket, so that on one hand, a connecting position can be sealed by the annular gasket, rainwater, a dust layer and the like are prevented from entering the connecting position,and the connecting position is prevented from rusting, and therefore dead connection is avoided, and disassembly is convenient; and on the other hand, through buffering of the annular cushion, scratching damage or extrusion and deformation are prevented when the nut abuts against the fixing structure, so that deformation damage is avoided; in the embodiment, the outer ring of a second ring part extends out of the end surface of the nut, so that all-dimensional protection and damage prevention of the nut are guaranteed; and the diameter of the inner ring of the second annular part is equal to the diameter of the inner ring of the nut so that the annular gasket can be prevented from blocking the nut to work.

Description

technical field [0001] The invention relates to the technical field of automobile fasteners, in particular to an antirust nut. Background technique [0002] The automotive fastener industry has extremely high requirements on the appearance and performance of products. Currently, iron rakes are used, which are constantly rubbed and bumped during use, resulting in damage to the outer coating of the product and rusting of the product. Some products are coated with plastic on the tooth ends of iron rakes, but the effect is found to be limited in the actual use process. The method of using plastic coating makes the original heavy rakes heavier, which increases the burden on users. At the same time, the coated plastic The friction coefficient with the iron teeth is small, and it is easy to fall off, resulting in a waste of working time. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an ant...

Some products are coated with plastic on the tooth ends of iron rakes, but the effect is found to be limited in the actual use process. The method of using plastic coating makes the original heavy rakes heavier, which increases the burden on users.
