Description

Technical Field

[0001] The utility model relates to the technical field of safety rope fixing, and more specifically, to a safety rope fixing mechanism. Background Art

[0002] When working at height, the upper end of the safety rope needs to be fixed to prevent workers from falling suddenly and causing accidents. The safety rope is generally fixed to a structure protruding from the roof, such as being bolted around the air duct or flue on the top floor of the building. However, for some buildings with no protruding structures on the roof, the existing safety rope generally needs to be pre-drilled at the fixing point, and then the safety rope is fixed to the drilled hole at the fixing point with an expansion bolt, and the safety belt is conveniently fixed through a fixing mechanism, but there is a problem that the range of workers' movement is limited;

[0003] When a wider wall needs to be constructed, ear plates are usually fixed on both sides of the wall and the ends and middle of the wire rope are fixed and supported by bolts and nuts. When workers are working, they can hang the safety belt and the wire rope to allow workers to move on the wall to carry out large-scale construction.

[0004] However, in actual use, the two ends and the middle of the wire rope are fixedly supported by fixing the ear plates and the inserted bolts and nuts. When installing, the bolts and nuts need to be separated so that the bolts pass through the ear plates and are rotated to fit the nuts. The bolts and nuts are in a separated state, and it is easy for the nuts to fall off or be lost, resulting in the inability to install the limit position, affecting the installation and use effect. Therefore, a safety rope fixing mechanism is proposed. Utility Model Content
