Abstract

This utility model is related to a kind of Anti-hook releasing device, including hook body and anticreep spring it is characterised in that：It is provided with three one-to-one limited posts in the left and right sides of hook body from bottom to up, it is respectively the first limited post, the second limited post and the 3rd limited post, anticreep spring is wound around successively and forms U-shaped jump ring by the first limited post, the second limited post and the 3rd limited post, and the wherein second limited post is the fulcrum of U-shaped jump ring.Being provided with three limited posts makes anticreep spring form U-shaped jump ring, can prevent weight from breaking off relations, hook, decoupling device are convenient, practical, it is to avoid during decoupling device, weight binding or wire line hitch are stuck in hook and are not easily taken out of phenomenon.

Description

A kind of Anti-hook releasing device

Technical field

This utility model is related to the technical field of crane safety device, particularly a kind of Anti-hook releasing device.

Background technology

No matter being the plant building in iron and steel enterprise, or the scene in construction site, heavy-duty machinery such as crane, bridge-type rises Heavy-duty machine all can be seen everywhere, and suspension hook mechanically all can have a kind of suspension hook Anti-hook releasing device, it can be seen that having in working at ordinary times A lot of Anti-hook releasing devices all lose effect, and in the case of this failure of apparatus, handling weight is breakneck, does not just note Security incident can occur.Existing Anti-hook releasing device is to be made up of a spring and tabletting, and the elastic force using spring itself will be pressed , in gib head, thus playing mousing-hook effect, but after using a period of time, often spring failure, tabletting is lost in piece tightly dieback The situation lost.

Utility model content

The purpose of this utility model is to provide one kind to overcome the deficiencies in the prior art, and structure simply prevents weight from breaking off relations, Hook, the convenient Anti-hook releasing device of decoupling device.

In order to complete above-mentioned purpose, the technological means that this utility model is taken are：

A kind of Anti-hook releasing device, including hook body and anticreep spring, sets from bottom to up in the left and right sides of hook body It is equipped with three one-to-one limited posts, the respectively first limited post, the second limited post and the 3rd limited post, anticreep spring is successively It is wound around and U-shaped jump ring is formed by the first limited post, the second limited post and the 3rd limited post, the wherein second limited post is U-shaped jump ring Fulcrum.

The second described limited post is than the first spacing pillar height 15mm～18mm.

The 3rd described limited post is than the second spacing pillar height 25mm～30mm.

The maximal tensility of described anticreep spring is 5mm～10mm.

The first described limited post and two limited posts are arranged at the outside hook of hook body, and the 3rd limited post is arranged on At the inner vertical of hook body.

The beneficial effects of the utility model are：Being provided with three limited posts makes anticreep spring form U-shaped jump ring, can prevent Weight breaks off relations, hook, decoupling device are convenient, practical, it is to avoid during decoupling device, weight binding or wire line hitch are stuck in hook and are not easily taken out Phenomenon.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

In figure, the 1, first limited post, the 2, second limited post, the 3, the 3rd limited post.

Specific embodiment

This utility model is a kind of Anti-hook releasing device, and being provided with three limited posts makes anticreep spring form U-shaped jump ring, permissible Prevent weight from breaking off relations, hook, decoupling device are convenient, practical, it is to avoid during decoupling device, weight binding or wire line hitch are stuck in hook and are difficult The phenomenon taken out.

With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.

Specific embodiment, as depicted in figs. 1 and 2, a kind of Anti-hook releasing device, including hook body and anticreep spring, is hanging The left and right sides of hook body is provided with three one-to-one limited posts from bottom to up, and the respectively first limited post 1, second is spacing Post 2 and the 3rd limited post 3, the first described limited post 1 and two limited posts 2 are arranged at the outside hook of hook body, and the 3rd Limited post 3 is arranged at the inner vertical of hook body, and anticreep spring is wound around successively by the first limited post 1, the second limited post 2 Form U-shaped jump ring with the 3rd limited post 3, the wherein second limited post 2 is the fulcrum of U-shaped jump ring.

The described high 15mm～18mm of the second limited post 2 to the first limited post 1, described three limited post 3 to the second limits The position high 25mm～30mm of post 2, the maximal tensility of described anticreep spring is 5mm～10mm.

This utility model, in decoupling device, the anticreep spring at the 3rd limited post 3 is broken into two with one's hands, limits the 3rd during hook again Anticreep spring at the post 3 of position restores.Make anticreep spring form U-shaped jump ring due to being provided with three limited posts, can prevent Weight breaks off relations, hook, decoupling device are convenient, practical, it is to avoid during decoupling device, weight binding or wire line hitch are stuck in hook and are not easily taken out Phenomenon.
