Abstract

The invention discloses an anti-loose hook with a hanging rod equipped with a bolt. The hook comprises a hook, a hanging ring, the anti-loose sleeve and the bolt, wherein the hook comprises a verticalhanging rod body and a J-shaped hook connected to the lower end of the hanging rod, the hanging ring is hung on the J-shaped hook, the anti-loose sleeve is provided with a horn hole with a large upper part and a small lower part, and sleeve the hanging rod from top to bottom, and the anti-loose sleeve horn hole covers the J-shaped hook; when the anti-loose sleeve horn hole covers the J-shaped hook, the bolt is transversely inserted into a hanging rod hole of above the upper end surface of the anti-loose sleeve, one end of the bolt is provided with a shaft head, and the other end of the bolt is sleeved with nuts and is in threaded connection with the nuts; and the hook is improved in that the two nuts are arranged on the bolt in a sleeved mode and are in threaded connection with the bolt.According to the hook, the anti-loose sleeve can be prevented from moving upward so as to prevent the hanging ring from falling off from the J-shaped hook, the bolt is not prone to fall off, and the anti-loose effect is good.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a suspension hook. Background technique [0002] Commercially available hooks comprise hooks and suspension rings, and hooks comprise vertical suspenders, J-shaped hooks connected to the lower end of the suspenders, and suspension rings are hung on the J-shaped hooks. In order to solve the problem that the lifting ring is easy to disengage from the J-shaped hook, some hooks are equipped with anti-loosening sleeves. The horn escutcheon is on the J-hook, but this type of hook also has a flaw: once the locking sleeve is moved up to the point where the ring can be disengaged from the J-hook, it will not prevent loosening. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an anti-loosening hook that can limit the upward movement of the anti-loosening sleeve to prevent the suspension ring from being disengaged from the J...
