safety hook

Abstract

A safety hook comprises a hook body with an opening. Rotating rings are arranged at opposite ends of the opening, an anti-dropping latch is hinged inside the hook body, and the safety hook is provided with a safety lock kept on the anti-dropping latch to slide and a spring supported between the hook body and the anti-dropping latch. A latch arm of the anti-dropping latch usually seals the upper portion of the opening due to elastic force of the spring, a notch is positioned below the latch arm, and the notch and the lower portion of the opening define a sealed ring so as to be mutually buckled with a buckling ring of a connecting object. When sliding to a locked position, the safety lock can have a latch locking function on the anti-dropping latch, and the problem that the opening is opened due to maloperation of the anti-dropping latch, so that the buckling ring drops from the hook body is solved; when the safety lock slides to an unlocked position, the anti-dropping latch is allowed to be operated, the latch arm swings outwards to leave the opening, and the buckling ring is taken down from the hook body conveniently.

Description

technical field [0001] The invention relates to a safety hook, in particular to a safety hook equipped with a safety lock. Background technique [0002] figure 1 A cross section of a Swivel Snap Hook 80 is shown. The rotating hook 80 includes a hook body 81, and an anti-off latch 82 supported on the hook body 81 to slide. One end of the hook body 81 forms a hook portion 85 for hooking the connection object 70, such as a pet collar and a pet safety belt. Buckle 71 on the articles such as; The other end of hook body 81 forms a journal 86, for installing a swivel 83, and this swivel 83 is in order to connect a webbing 90 or the like, such as rope, chain etc. There is also a spring 84 that uses compression force to act between the hook body 81 and the anti-off latch 82, so that the anti-off latch 82 is kept at the position of the closed hook portion 85 by its elastic force, so that the hook portion 85 and the anti-off latch 82 A closed ring 87 is defined, so that it is interl...

AI Technical Summary

Problems solved by technology

However, this protruding latch handle 88 and 88a is likely to be mismoved by the buckle 71 or other external forces, so that the anti-off latches 82 and 82a are automatically opened, and the hooks 85 and 85a are opened, causing the buckle 71 to fall off and lose its function. Connection effect, in serious cases, may also lead to accidents

For example, a dog that was originally tied up may suddenly rush out because of this accidental detachment, resulting in accidents such as being hit by a car or even biting a passerby.
