Description

Improve antiseptic property's fastener structure for vehicle Technical Field The utility model relates to the technical field of fasteners, in particular to a vehicle fastener structure for improving corrosion resistance. Background The fastener for the automobile is a small mechanical part and is mainly used for connecting and fixing various parts of the automobile so as to ensure the stability and the safety of the automobile structure. These fasteners are typically made of metal and have different shapes and sizes to accommodate various application requirements in automotive manufacturing. The connection modes of the vehicle fastener are various, including bolt connection, stud connection, screw connection and the like. The existing fastener can cause the loosening phenomenon of nuts under the vibration working environment for a long time, so that the connection of automobile parts is not tight enough, safety hidden danger is brought in the running process of the automobile, the connectors are dropped, and even safety accidents are caused; The prior patent (bulletin number: CN 220396232U) discloses a fastener with a limiting structure for mounting automobile parts, which comprises a bolt head, a bolt rod and a nut, wherein the bolt rod is fixedly connected to the center of the bottom of the bolt head, a first anti-slip gasket is movably connected to the lower part of the bolt head, a second anti-slip gasket is movably connected to the upper part of the nut, a positioning block is fixedly mounted on the outer side wall of the nut, and a screw hole is formed in the contact position of the bolt rod and a fixing bolt. Through the setting of gag lever post and fixed cover, when the nut was twisted and is changeed on the bolt pole, alright insert the gag lever post inside spacing hole, guaranteed the steadiness of nut on the bolt pole from this, nut also hardly takes place not hard up when making the car vibrate, strengthened the stability and the holistic security of car spare part. To the above-mentioned problem, though through setting up gag lever post and fixed cover, the stability and the overall security of car spare part have been strengthened when the nut was twisted on the bolt pole to current patent, but its anticorrosive performance still remains to promote. In the long-term use process of the fastener, the fastener is easy to corrode due to substances such as moisture in the air, and further is broken or rusted, so that the service life of the fastener is shortened. Disclosure of Invention The utility model aims to provide a vehicle fastener structure for improving corrosion resistance, which can be used for sleeving a protective piece on a bolt head, and can be used for adsorbing and fixing the protective piece under the cooperation of a first magnet and a second magnet, so that the contact of liquid with the surface of the bolt head can be effectively reduced, and further the corrosion resistance is further improved, and the problems in the background art are solved.
