Lifting hook integrally molded by bending

Abstract

The invention provides a lifting hook integrally molded by bending, which comprises a lifting ring, a connecting hole in the middle of the lifting ring, a hook part integrally molded with the lifting ring in a bending manner and a bearing hole disposed along a central axis direction of the hook part. The lifting hook is characterized in that a protection plate annularly sleeves a joint between the lifting ring and the hook part; reinforcing bodies are arranged on both sides of the bottom of the hook part around the central axis of the bearing hole; and strip-type slots parallel with the central axis of the bearing hole are arranged on the bearing hole, and the strip-type slots extend to the edge of the reinforcing body at the other side of the hook part from the edge of the reinforcing body at one side of the hook part. The joint between the lifting ring and the hook part as well as the bearing hole are both reinforced, such that breakage in these two positions due to a larger stress is avoided, potential safety hazards are reduced, and due to the strip-type slots at the bearing hole, friction between an object and the hook part is increased and an instable stress caused by sliding of the object at the bearing hole in an operation process is prevented.

Description

technical field [0001] The invention specifically relates to a hook that is integrally bent and formed. Background technique [0002] The hook is a kind of spreader commonly used in hoisting machinery. It is generally composed of a lifting ring and a hook connected to the lifting ring. The connection method is divided into one-piece bending forming and split connection. Because of the small cross-sectional area of ​​the hole, it is easy to break during use. Secondly, the connection between the suspension ring and the hook part will also be easily broken due to excessive force, resulting in a potential safety hazard. Contents of the invention [0003] In order to solve the above technical problems, the technical solution provided by the present invention is: an integrally bent and formed hook, including a suspension ring, a connecting hole in the middle of the suspension ring, a hook part integrally bent and formed with the suspension ring, along the The bearing hole set i...
