Description

Self-adaptive heavy pulley adjusting device for panoramic doors and windows Technical Field The utility model relates to the field of doors and windows, in particular to a self-adaptive heavy pulley adjusting device for panoramic doors and windows. Background At present, the sliding door and window performs sliding by installing a pulley assembly at the top or bottom of the door and window frame so as to realize the purposes of opening and closing the sliding door and window. In the existing pulley assembly for sliding doors and windows, as disclosed in Chinese patent literature, the patent application number is 202121760216.X, the technical scheme of the patent application number is named as a double-directional sliding door buffer and a moving door frame, and the scheme mainly comprises a shell, and a first pulley group and a third pulley group which are arranged at two ends of the shell, wherein the first pulley group and the third pulley group respectively consist of a wheel frame, a wheel shaft, a concave pulley, a spherical shaft sleeve, a sliding door mounting hanging box, a connecting screw rod, a nut seat and a nut. When the guide rail is deformed and uneven, the gap and the spherical shaft sleeve formed between the nut seat and the nut can realize automatic adaptation swing adjustment. In practical applications, however, the pulley assembly of this solution has the following drawbacks: The clearance that forms between spherical axle sleeve, nut seat and the nut of this scheme only can make the left and right sides concave wheel of first wheelset and third wheelset in the slip direction make the mutual jump formula swing adjustment from top to bottom to solve the smooth and easy problem of slip that the pit type deformation appears in the guide rail. When the gradient appears after the guide rail is deformed, the first wheel set and the third wheel set cannot realize pitching and swinging adjustment along the sliding direction, so that the guide rail with the gradient cannot be smoothly slid, and therefore, the self-adaptive adjustment range of the scheme is very limited.
