Safety handle of fall arrestor

Abstract

A safety rope handle for a fall arrestor includes a handle body comprising a top support and a grip section connected in sequence. A steel cable channel is formed within the handle body, penetrating the top support and grip section. The safety rope of the fall arrestor passes through the steel cable channel. A loop is formed at the end of the safety rope that exits the steel cable channel and faces away from the top support. A spring is also provided within the steel cable channel, with its two ends fixed to the wall of the steel cable channel and the portion of the safety rope located within the steel cable channel, respectively. When the user pulls the safety rope out of the fall arrestor, because the spring connects the handle body and the safety rope, even if the handle body is higher than the fall arrestor, it will not slide down along the safety rope and disengage from the position near the loop, allowing the user to easily operate the safety rope by gripping the handle section at any time.

Claims

1. A safety rope handle for a fall arrestor, comprising: The handle body includes, along a central axis, a top support and a grip, which are connected to each other; a steel cable channel is formed within the handle body, which passes through the top support and the grip along the central axis; a safety cable passes through the steel cable channel, and a loop is formed at the end of the safety cable away from the top support; and a spring, which is a helical spring extending along the central axis, is located within the steel cable channel and sleeved on the safety cable, with a first fixing part and a second fixing part formed at both ends of the spring, the first fixing part being fixed to the wall of the steel cable channel, and the second fixing part being fixed to the portion of the safety cable located within the steel cable channel.

2. The safety handle of the fall arrester as claimed in claim 1, wherein a fixed section is formed on the wall surface of the cable channel corresponding to the portion of the handle adjacent to the top rest; the first fixed portion of the spring is fixed to the fixed section.

3. The safety rope handle of the fall arrester as described in claim 2, wherein the fixing section is a tapered hole; the first fixing part is embedded in the fixing section.

4. The safety cable handle of the fall arrester as described in any one of claims 1 to 3, wherein a first opening is formed at one end of the cable channel corresponding to the abutment portion, and a second opening is formed at the other end of the cable channel corresponding to the grip portion; the safety cable includes a cable and a spring retaining ring; the cable passes through the cable channel, the first opening and the second opening, the loop is formed at one end of the cable exiting the second opening, the spring retaining ring tightly binds and fixes the cable, and at least a portion of the spring retaining ring passes through the second opening and is located within the cable channel, the second fixing portion is a straight rod extending along the central axis, and the second fixing portion is inserted into the spring retaining ring for fixation.

5. The safety cable handle of the fall arrester as described in claim 4, wherein the handle itself has an elastic structure, and a plurality of openwork transverse grooves are formed on the top abutment, the transverse grooves being formed on the top abutment in a manner surrounding the cable channel, the transverse grooves communicating with the cable channel respectively, and the direction in which the transverse grooves extend is perpendicular to the central axis.
