The invention provides a fastener structure. The fastener structure comprises a fastening block, steel pins, snap teeth, antiskid lock catches, angle iron, oil dripping holes, a rubber ring, inner teeth, a supporting ring, a steel ring and a buckling groove. The snap teeth are installed on the outer surface of the fastening block and connected with the fastening block through the steel pins. Each antiskid lock catch is arranged on one side of the corresponding snap tooth and internally provided with the corresponding oil dripping hole. The steel pins are tightly connected with the antiskid lock catches through the angle iron. The rubber ring is arranged on the inner surface of the fastening block and installed on the outer surface of the supporting ring. The steel ring is arranged on the inner surface of the supporting ring. The inner teeth and the buckling groove are arranged on the inner surface of the steel ring. The structure is compact, and disassembling and assembling can be effectively carried out; as the internally-formed oil dripping holes, lubricating oil can be dripped into the fastener structure, the structure is not prone to being rusted in the use process accordingly, long-time use of the structure can be well guaranteed, and the service life is prolonged; due to the internally-arranged inner teeth and the internally-arranged buckling groove, a fastened piece can be effectively locked.
Description
technical field [0001] The invention relates to a fastener, in particular to a fastener structure, and belongs to the technical field of fastening. Background technique [0002] With the continuous advancement of science and technology and the continuous development of the machinery industry, some small parts have also received more and more attention. It should be because they want to produce some high-end precision instruments and have higher requirements for parts. The fastening of parts is particularly important. Some machinery is due to the fact that some parts are not fastened well during operation, resulting in loosening during movement, which will bring some economic losses and human safety. Fasteners are widely used in many fields. There are better prospects. [0003] At present, there are many deficiencies in fasteners. Oil, dust, acid, alkali, salt, etc. attached to the surface of the workpiece are converted into corrosive media under certain conditions, and chem...
