Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically a wheel body and a door and window pulley. Background Technology

[0002] Sliding doors and windows are often equipped with rollers between the rollers and the frame to reduce resistance and facilitate sliding. Common types of rollers include plastic and metal rollers. Plastic rollers consist of a bearing and a plastic outer ring covering the bearing. Plastic rollers have poor load-bearing capacity, especially under prolonged static load. The plastic outer ring is prone to deformation or localized indentations under pressure, leading to uneven sliding, bouncing, and abnormal noises.

[0003] Existing metal pulleys consist of a bearing and a metal wheel body surrounding the bearing. While metal pulleys are less prone to indentation, once deformed, they cannot be restored, severely impacting their usability. Furthermore, metal pulleys are susceptible to corrosion over prolonged use, increasing friction with the track and making doors and windows difficult to close. Additionally, the friction between the metal outer ring of the pulley and the track in the door and window frame during movement generates significant noise. Therefore, those skilled in the art have provided a wheel body and a door / window pulley to address the problems mentioned in the background section. Utility Model Content
