The invention relates to the technical field of fastening devices, in particular to a fastening bolt with a built-in elastic turnover limiting device. The fastening bolt comprises a top bolt head, anintegrated transverse screw rod fixed in the center of the outer side of the top bolt head, and an inner nut in threaded connection with the transverse screw rod. The fastening bolt with the built-inelastic turnover limiting device is provided with the top bolt head, the transverse lead screw and the inner nut, an arc-shaped telescopic groove internally provided with an internal thread assemblingblock and a middle adjusting opening used for adjusting the angle are formed in the inner nut, the internal thread assembling block is adjusted to be staggered with threads on the outer side face ofthe transverse screw rod, the transverse screw rod is provided with a lateral containing groove internally provided with an angle-adjustable external thread matching block, and therefore the locking performance of the fastening bolt is improved, and the assembling firmness and stability of the fastening bolt are improved; and the external thread matching block is formed by assembling an internal installation cover and an external thread assembling block, and assembling, disassembling and adjusting are easy and convenient.
Description
technical field [0001] The invention relates to the technical field of fastening devices, in particular to a fastening bolt with a built-in elastic turn-over limiting device. Background technique [0002] Bolt is a general term for fasteners, and it is a tool for gradually tightening the mechanical parts of objects by using the physical and mathematical principles of the oblique circular rotation and friction of the object. The utilization of visible bolt is extensively. The operation strategies of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods. Ships and ships, vehicles, hydraulic engineering, even also use bolt in chemical experiment. Anyway it is that super many places are useful bolt. The special precision bolt used above such as digital product. DVD, miniature bolts used in cameras, glasses, clocks, electronics, etc.; general bolts used in televisions, electrical products, musical instruments, fur...
