Abstract

The utility model relates to an anti-off hook and aims at providing an anti-off hook with simple structure, easy manufacturing and safe and convenient usage. The hook comprises two hooks with similar appearances; the hook is provided with a connecting hole; and the anti-off hook is characterized in that the two hooks are arranged in a face-to-face way and form a closed ring by mutual superposition through the connecting holes. When in use, the anti-off hook can firstly sleeve a hoisting rope in one hook, then rotate the other hook to lead the hook to be also sleeved in the hoisting rope, then the hoisting rope is sleeved in the closed ring formed by the two hooks arranged in a face-to-face way, and can not be automatically linked off the anti-off hook, and since the two hooks can be stressed simultaneously, the hoisting rope can be conveniently taken off the anti-off hook artificially.

Description

The anticreep hook

Technical field

The utility model relates to a kind of lifting device, particularly a kind of anticreep hook.

Background technology

Whether often can use hook in weight-lifting equipment, but common hook does not have safety mechanism, it is reliable with being connected of hook to pay close attention to derrick line in the lifting process, and many personal injury accidents take off just because of derrick line ring on hook and cause.

The utility model content

The purpose of this utility model provides a kind of anticreep simple in structure, easy to manufacture, safe and convenient to use hook.

In order to satisfy above-mentioned requirements, the utility model is achieved through the following technical solutions: it includes two hooks that profile is roughly the same, on hook, all be shaped on connecting bore, it is characterized in that these two hooks are installed face-to-face to overlap through connecting bore to form closed annular.Can also be shaped on the locating piece of projection on wherein one the Hook of two hook adjacent surfaces, the position of described locating piece is the open front at adjacent hook.

This anticreep hook in use, derrick line at first can be inserted in the hook wherein, rotate another part hook then, should link up with also is inserted in the derrick line, derrick line just is enclosed in two and links up with in the formed closed annular face-to-face, derrick line just can not deviate from from the anticreep hook automatically, and two hooks are simultaneously stressed, and is very convenient with manually taking out derrick line from the anticreep hook yet.
