Problems solved by technology

[0006] The main function of the above two kinds of anti-loosening nuts is only reflected in the self-loosening prevention of nuts, but the self-loosening prevention of bolts has not yet been realized. The main reason is that nuts are easier to self-loosen than bolts.

Abstract

The invention relates to the technical field of machine parts, in particular to a multifunctional anti-loosening bolt nut. The multifunctional anti-loosening bolt nut comprises a bolt jointed rod piece, a fastening nut and a locking nut, wherein a main body of the bolt jointed rod piece is provided with a fastening bolt jointed part; at least one end of the bolt jointed rod piece is provided witha locking bolt jointed part; the fastening bolt jointed part is provided with an external thread structure; the locking bolt jointed part is provided with an external thread structure or an inner bolthole structure; the screwing direction of the fastening bolt jointed part is opposite to the screwing direction of the locking bolt jointed part; a first inner hole and a second inner hole are formedin the locking nut; when the fastening bolt jointed part is of an external thread structure, the second inner hole is provided with an inner bolt hole structure; and when the locking bolt jointed part is of an inner bolt hole structure, the second inner hole is provided with an external thread structure. The self-loosening phenomenon of the bolt nut can be prevented from occurring and developing,thus preventing potential safety hazards even accidents from occurring. The multifunctional anti-loosening bolt nut has the functions of thread water prevention and dust prevention.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a multifunctional anti-loosening bolt and nut. Background technique [0002] Bolt and nut type fasteners are used in various industries with connection and fastening requirements, such as aerospace, military industry, ships, wind power, boilers, tower and mast structures, railways, bridges, construction machinery, transportation vehicles, construction machinery , agricultural machinery, manufacturing machinery, etc. are widely used. For these large-scale equipment, facilities or devices, especially those under frequent dynamic operation, coupled with the harsh working environment and heavy loads, the bolt and nut fasteners are subject to vibration in all directions and the impact of the load, making the bolts and nuts relatively weak. It is easy to loosen, resulting in the reduction or even failure of the fastener function, resulting in a great safety hazard or accident...
