The invention belongs to the technical field of door and window hardware fittings, and relates to an extremely narrow pulley which comprises a connecting shaft, a bearing and a pulley body with a track groove in the periphery, one end of the connecting shaft is fixedly connected with the pulley body, the other end of the connecting shaft is rotatably inserted into an inner ring of the bearing, and the pulley body can rotate relative to the bearing through the connecting shaft; reinforcing pieces are arranged at the bottoms of the track grooves and on the wheel body. The wheel body is made of plastic materials, and the reinforcing piece is made of metal materials. Compared with a traditional wheel body made of a single plastic material, the strength of the wheel body provided with the reinforcing piece is higher, and deformation or indentation is not prone to being generated in the supporting process; meanwhile, compared with a wheel body made of metal materials, the wheel body made of plastic materials has the advantages of being easy to machine, low in cost, easy to form and the like in the mode that the reinforcer is arranged in the wheel body made of the plastic materials.
本发明属于门窗五金配件技术领域，涉及一种极窄滑轮，包括连接轴、轴承以及外周设有轨道槽的轮体，连接轴的一端与轮体固定连接，另一端转动插接于轴承的内圈上，且轮体能够通过连接轴相对于轴承转动；其中，于轨道槽的槽底，轮体上设置有加强件；轮体由塑胶材料制成，加强件由金属材料制成。相比于传统的由单一塑胶材料制成的轮体，设置加强件的轮体的强度更高，不容易在支撑的过程中变形或产生压痕；同时相比于由金属材料制成的轮体，通过在由塑胶材料制成的轮体内置加强件的方式，具有加工简单、低成本、易成型等优点。
