Abstract
The invention discloses an automobile fastener, comprising a screw head, a groove, a screw rod, a cavity, a sliding part, a screw cap and an inverted cone part. A first screw head cover is slidably connected to the outer side of the screw head, and a second screw head cover is slidably connected to the outer side of the first screw head cover. A gasket is connected to the lower end of the screw head, and a first anti-slip strip is arranged on the surface of the lower end of the gasket. The screw rod is connected to the middle of the lower end of the gasket, and the inverted cone part is arranged at the lower end of the screw rod. According to the automobile fastener, the screw head can be rotated by inserting a plum screwdriver into a plum groove, thereby rotating the screw rod; the screwrod is lifted and lowered under the action of a threaded hole, thereby controlling the lifting of a screw tip; and the lowered screw tip pushes the sliding part to slide outwards so as to press against the inner side wall of a fastened part, so that the fastening performance of the automobile fastener is improved, and loosening is not likely to happen. The spring provided in the invention facilitates retracting the outer end of the sliding part into the sliding cavity when disassembling the automobile fastener.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto fastener. Background technique [0002] Fasteners are mechanical parts used for fastening connections. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, and hydraulics. They are used in various machinery, equipment, vehicles, ships, etc. Various fasteners can be seen on items such as railways, bridges, buildings, structures, tools, instruments, chemicals, and instruments. They are the most widely used mechanical basic parts. The fasteners are characterized by varieties and specifications. There are many, and the performance uses are different. [0003] However, the existing fasteners have a single structure, general fastening performance, easy loosening, and inconvenient disassembly and assembly. Therefore, those skilled in the art provide an automobile fastener to solve th...
