The invention relates to an anti-falling bolt, an anti-falling bolt assembly and a using method of the anti-falling bolt assembly. The anti-falling bolt comprises a bolt body and a limiting structure,wherein the bolt body comprises a screw provided with a thread and a screw head fixed to the first end of the screw; the second end, opposite to the first end, of the screw is provided with a containing groove in the length direction of the screw and a limiting groove formed in the circumferential direction of the screw and communicating with the containing groove; the limiting structure is rotationally embedded and arranged in the screw; the limiting structure can rotate to be clamped to the limiting groove and protrude out of the surface of the screw, or the limiting structure can rotate tobe put away in the containing groove, and therefore it is prevented that a nut falls off from the second end; and the safety of mechanical construction is guaranteed, the mechanical service life is prolonged to a certain extent, the safety of a machine is improved, and the service life of the machine is prolonged. The structure is simple, operation is convenient, and achieving is easy.
Description
technical field [0001] The invention relates to the field of building construction, in particular to an anti-falling bolt, an anti-falling bolt assembly and a method for using the same. Background technique [0002] In the process of building construction, the use of various types of machinery is essential. Bolt assemblies are often used to fasten two or more components that need to be fastened together. A bolt assembly consists of a bolt and a nut. The bolt includes a bolt head and a bolt rod connected with the bolt head, and the bolt rod is provided with threads. When in use, the bolt rod is passed through the through holes of two or more parts, and the nut is screwed onto the screw rod with the thread, so as to realize the fastening of two or more parts together. [0003] However, due to the vibration of the machine used all the year round, the nut will slowly loosen from the bolt rod over time, which will cause the parts to loosen or even fall off, which greatly affec...
