A hook and sleeve integrated connecting device

Abstract

This invention discloses an integrated hook-and-lasso connection device, designed to solve the problem of unreliable protection in high-altitude and water surface operations due to the lack of standard anchor points. The core of the device is a locking component with three through holes. A webbing passes through two of these holes via a friction-locking path. When fixing to irregularly shaped objects such as cylinders, the webbing wraps around the object, and the hook-shaped connector attached to the webbing passes through the first through hole of the locking component, forming a closed lasso and locking it in place. This device is simple in structure and easy to operate, integrating both "direct hooking" and "lasso locking" functions, greatly improving operational safety in specific scenarios.

Description

Technical Field

[0001] This invention belongs to the field of safety protection technology, specifically relating to a fall protection connection device for high-altitude and water surface operations. Background Technology

[0002] In high-altitude and water-based work scenarios, such as ship pilotage and construction, workers often face the predicament of a lack of anchor points. The site may only have smooth cylindrical handrails, thick pipes, square tubes, angle iron, or other irregularly shaped structures, making it impossible for traditional safety hooks to reliably engage, resulting in ineffective fall protection for personnel. Existing solutions mostly rely on rope knots for fixation, which is not only cumbersome and time-consuming, but also difficult to perform properly under adverse conditions such as slippery conditions, muddy surfaces, and when wearing thick gloves, leading to low reliability and safety hazards. Summary of the Invention

[0003] This invention provides an integrated hook-and-lasso connection device, aiming to solve the problem in existing technologies where connection devices cannot quickly and reliably secure themselves when there are no standard anchor points. The device uses a specially designed three-hole metal locking plate in conjunction with a standard quick hook and webbing to achieve rapid switching between two securing modes: "directly hooking to an anchor point" and "forming a lasso around any object." Its core structure is a metal plate with three rectangular through holes—the top hole is for hooking, and the middle and bottom holes are for webbing. A crossbar is positioned between the two webbing holes. The webbing passes through the middle and bottom webbing holes in an S-shaped path and is locked in place by friction with the crossbar; the quick hook is connected to one end of the webbing. When lassoing is required, the webbing wraps around the target object, and the hook tip of the quick hook passes through the hook hole, forming a closed lasso and locking it in place.

The markings in the diagram are as follows: 1-locking component, 2-first through hole, 3-second through hole, 4-third through hole, 5-flexible load-bearing component, 6-hook-shaped connector, 7-crossbar. Detailed Implementation

[0005] This device has two operating modes. Mode 1: Direct Hook Mode. When there is a standard anchor point at the working location, such as a pull ring, simply hook the quick hook onto the anchor point. The webbing is locked in place by the three-hole locking plate, providing a reliable anti-fall connection. Mode 2: Lasso Locking Mode. When there is no standard anchor point at the working location, wrap the webbing around any cylindrical or irregularly shaped object, then pass the hook tip of the quick hook through the hook hole of the three-hole plate. Pull the free end of the webbing taut, and the webbing will be locked in place by the friction of the crossbars in the two threading holes, forming a tight, closed lasso that is firmly locked to the object.

Claims
