Problems solved by technology

[0002] Bolt connection is one of the most commonly used connection methods. People often use bolts to fasten objects. When using it, it is necessary to avoid the problem that the bolts loosen by themselves and cause the connection to be unstable. Nowadays, ordinary bolts generally use gaskets in the anti-loosening design Or add nuts for anti-loosening, but the anti-loosening effect of ordinary double nuts is not ideal, and the anti-loosening effect decreases with the increase of vibration frequency and time

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it can be set directly on the other ...

Abstract

The invention discloses an anti-falling fastening device. The anti-falling fastening device comprises a rod piece and two or more nuts; two sets of threads with opposite screwing-in directions are arranged on the periphery of the rod piece; the two nuts are mounted on the rod piece in a sleeving mode and screwed on the threads with different screwing directions correspondingly; and the side facesof the face-to-face sides of the two nuts are each provided with one or more sets of lock ribs which are mutually matched and connected in an abutting mode. The double-thread and double-nut anti-falling design is adopted, the interlocking function of the double nuts is achieved through lock rib structures on the double nuts, and the anti-falling effect is improved.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an anti-off fastening device. Background technique [0002] Bolt connection is one of the most commonly used connection methods. People often use bolts to fasten objects. When using it, it is necessary to avoid the problem that the bolts loosen by themselves and cause the connection to be unstable. Nowadays, ordinary bolts generally use gaskets in the anti-loosening design Or add nuts for anti-loosening, but the anti-loosening effect of ordinary double nuts is not ideal, and the anti-loosening effect decreases with the increase of vibration frequency and time. Contents of the invention [0003] The invention provides an anti-loosening fastening device, which adopts a double-threaded, double-nut anti-loosening design, and realizes the interlocking function of the double nuts through the locking protrusion structure on the double nuts, thereby improving the anti-loosening effec...
