Description

A new type of nylon directional pulley Technical Field

[0001] This utility model relates to the field of directional pulley technology, specifically to a novel nylon directional pulley. Background Technology

[0002] A pulley is a simple machine used to lift heavy objects with less effort. A pulley is a simple machine with grooves around its perimeter, consisting of a grooved disc that can rotate around a central axis and a flexible rope (rope, tape, steel cable, chain, etc.) that passes over the disc. Nylon pulleys are lightweight and easy to install at heights. With their unique advantages, they are gradually replacing old metal pulleys. Nylon pulleys can replace steel with plastic and are therefore widely used.

[0003] Chinese patent CN221397072U discloses a novel nylon directional pulley, which includes a nylon directional pulley body and an n-shaped connecting frame, wherein the nylon directional pulley body is rotatably connected to the inner side of the n-shaped connecting frame.

[0004] Although the aforementioned patent can ensure the stability and safety of cable transportation through the transmission and clamping structure, preventing the cable from falling off during transportation, dust and impurities accumulate on the surface of the nylon directional pulley body after long-term use. This increases the friction between the nylon directional pulley body and the cable, which in turn affects the smooth operation and transmission efficiency of the nylon directional pulley body. Therefore, there is an urgent need for a new type of nylon directional pulley to solve these problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:
