Self-locking lifting hook

Abstract

The invention relates to a self-locking lifting hook, comprising a lifting part and a hanging part. The lifting part is a lifting rod; the top end of the lifting rod forms a through hole used for passing of and connection with a lifting rope; the hanging part is two symmetrically arranged and spaced U-shaped hooks used for hanging members; the two U-shaped hooks are fixedly connected through a fixing block at the bottom, thereby forming an integrated body, and same-side arms of the two U-shaped hooks extend upwardly to form a connection arm; the tops of the connection arms and the lower part of the lifting rod are both provided with fixed holes; the lower part of the lifting rod extends to a position located between the two connection arms and is connected with the two connection arms by inserting pin shafts into corresponding fixed holes; and when the lifting rod is perpendicular to the connection arms, the length of the lifting rod in the U-shaped hooks is greater than the opening width of the U-shaped hooks. The self-locking lifting hook has the advantages of a simple structure, easy manufacturing and low cost; through a self-locking structure, lifting of an article is simple and easily practicable; due to the adjusting function, the self-locking lifting hook is applicable to different products; and the self-locking lifting hook substantially improves production efficiency and can effectively prevent slipping of the article.

Description

[0001] technical field [0002] The invention relates to a suspension hook, in particular to a self-locking suspension hook which can be automatically locked and prevent lifting objects from slipping in a working state. Background technique [0003] We know that hooks are very common in the daily production and transportation process. Traditional hooks are not only complex in structure and difficult to process, but also often decouple when the suspended items are heavy, resulting in product damage and There is great danger. At present, some manufacturers have adopted an external device to prevent decoupling, which not only increases the lifting steps and reduces work efficiency, but also increases the production or purchase cost of the external device to prevent decoupling, and increases the economic burden of the enterprise. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a self...
