Description

Technical Field

[0001] The utility model belongs to the technical field of limiters, and in particular relates to a rope limiter. Background Art

[0002] The rope limiter is also called a rope adjuster. The existing rope adjuster has the functions of locking the rope, shortening the rope, and releasing the rope.

[0003] However, most of the existing rope adjusters have structural limitations, which makes it extremely inconvenient to install or remove the main rope from the adjuster. The main rope needs to be inserted into the adjuster in one direction. When the rope is very long, the rope needs to be passed through for a long time to complete the rope assembly, which is inefficient. In addition, there are also some limiters that can fold the rope in half and then pass it through the limiter, such as the rope adjuster disclosed in application number 201922264645.7, which is achieved by folding the rope in half and then passing it into the limiter. However, this method has a disadvantage, that is, after the rope is folded in half, its cross-sectional size will become very large. If the aperture size of the limiter is small, it cannot pass through smoothly. Moreover, since the rope is elastic, the folded end will bounce up when inserted, so it needs to be compressed by external force. The operation is also very troublesome and the placement efficiency is not high.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies.

[0005] Therefore, in order to solve the above problems, the utility model provides a rope limiter. Utility Model Content
