Abstract

The invention provides a fall arrester. The fall arrester comprises a casing, wherein the casing comprises an outer retaining ring; one end face of the outer retaining ring is provided with a ring-shaped spine composed of a plurality of curved spine units; each spine unit comprises an engaging portion at one end and an engaged portion at the other end; the inner side of each spine unit is providedan arc-shaped abdomen; the outside of each abdomen is provided with a convex engaging piece; a rotating disc is arranged in the casing and a buckle portion is arranged in the inner sidewall of the rotating disc; a plurality of ratchet units are arranged on the rotating disc; one end of each ratchet unit is a locking end while the other end of each ratchet unit is a fixing end; one end of the rotating disc is provided with a fixing piece; the fixing end can be movably installed on the fixing piece; the locking end rotates to abut against the engaging piece; a pivot portion is arranged in the rotating disc; the pivot portion comprises a fixing sleeve and a rotatable fixed rotating shaft which fits with the fixing sleeve coaxially; and two ends of an elastic component are separately connected with the fixing sleeve and the buckle portion. According to the fall arrester, the requirements for installation accuracy are reduced, so that time and energy are saved in the installation process.

Description

technical field [0001] The invention relates to the field of safety rope equipment, in particular to a fall arrester and a fall arrester. Background technique [0002] At present, when encountering high-altitude operations such as building construction, air-conditioning installation, or fruit tree picking in daily life, it is necessary to wear safety equipment to operate the construction to avoid falling and causing accidents. Existing wearable safety equipment is mainly these two kinds of general suspension type fall arrester and traditional safety belt. The existing anti-fall device uses brake teeth to cooperate with the running wheel. The running wheel is an integral ratchet. There are multiple mounting holes on the running wheel. When assembling, it needs to align all the mounting holes at the same time to brake at the same time. The teeth need to be precisely adjusted in position, resulting in high requirements for assembly accuracy, which is time-consuming and labor-i...
