Description

Technical Field

[0001] The utility model belongs to the technical field of curtain pulley equipment, and in particular relates to a pulley capable of passing through a curved rail. Background Art

[0002] Most of the current curtain tracks are straight-track curtain tracks. However, as users have higher and higher requirements for the aesthetics of curtains, a curved curtain track has gradually appeared on the market. The curved curtain track can make the curtain design more flexible, meet user needs, and improve the aesthetics. However, the existing pulley has a limited turning radius within the curved curtain track, which can easily cause the pulley to get stuck or fall off during the sliding process, affecting the user experience.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document [201620745179.8] discloses a rotatable pulley for curtains, which includes a suspension arm for connecting to a hanging ring and a fixed block for mounting a pulley assembly. The suspension arm is connected to one side of the fixed block, and the fixed block includes a front half and a rear half that are hinged to each other. The pulley assembly has two sets, front and rear, respectively, located in the front and rear halves of the fixed block. The suspension arm is connected to the front half of the fixed block, and the rear half of the fixed block is connected to a suspension pulley.

[0004] The above solution solves the problem of limited turning radius of existing pulleys to a certain extent, but the solution still has many shortcomings. For example, there is no guide structure on the front and rear halves, and the pulley is easily offset during sliding, affecting the sliding smoothness. Summary of the Invention
