A locking safety hook for anti-falling

Abstract

The invention discloses a locking anti-falling safety hook, which comprises a support seat, a mounting groove, a mother-in-law strap, a silicone pad, a hinged seat, threading ears, a main limit plate, a limit hole, and a clamping part. There is a horizontal installation groove running through the front of the support seat, and a horizontal mother-in-law strap is movably inserted into the installation groove. A vertical silicone pad is fixed at the front end of the support seat, and a There is a vertical hinged seat. The invention can lock the rod-shaped object, and at the same time, the upper anti-slip rubber on the arc-shaped locking ring and the lower anti-slip rubber on the locking arc-shaped block can contact the rod-shaped object under the action of locking force. The outer wall is in contact, so that the upper anti-slip rubber and the lower anti-slip rubber form a large friction force with the surface of the rod-shaped object, thereby preventing the detachment of the fixed hook from the rod-shaped object and limiting the fixed hook on the rod-shaped object The axial position, which can play a strong decoupling effect.

Description

technical field [0001] The invention relates to a safety hook, in particular to a locking and anti-fall safety hook. Background technique [0002] In the engineering field, the use of safety hooks is mainly to protect the safety of high-level builders. Both ends of the safety rope are connected with safety hooks, the safety hook at one end is hooked on the semicircle on the safety belt, and the safety hook at the other end is hooked on other fixed buildings (anchor points) after climbing. The parameters of the safety hook are working tension and blasting tension. According to different standards and manufacturers, the parameters of the safety hook are also different. [0003] Traditional safety hooks mainly include "8"-shaped safety hooks and "D"-shaped safety hooks. In order to improve their adaptability, these two hooks and other hooks are often designed to be larger in size. It can be hung on objects of various sizes, but this design method has certain drawbacks, that i...

Problems solved by technology

[0003] Traditional safety hooks mainly include "8"-shaped safety hooks and "D"-shaped safety hooks, and these two types of hooks and other types of hooks are often designed to be larger in size in order to improve their adaptability. It can be hung on objects of various sizes, but this design method has certain disadvantages, that is, when encountering non-closed objects (such as non-closed spikes on electric towers), there is often a risk of decoupling, and when encountering In this case, you can only choose to hang it elsewhere to avoid the risk of decoupling, which brings inconvenience to production and life, and highlights the shortcomings of traditional safety hooks.
