Abstract

The invention discloses a mute sliding rail wheel set which comprises an idler wheel shelf containing idler wheels. The idler wheel shelf is arranged in a housing in a sleeved mode. Transverse bolts and a traction screw connect the idler wheel shelf with the housing horizontally and longitudinally, and a sound absorption cotton layer is arranged on the inner wall of the idler wheel shelf. According to the mute sliding rail wheel set, the sound absorption cotton layer is arranged on the inner wall of the idler wheel shelf, so that noise generated by the sliding rail wheel set is greatly attenuated, and a mute effect is achieved. In addition, sound absorption cotton is internally mounted so as to be not likely to be damaged or fall off, and the service life is long. The mute sliding rail wheel set is easy to manufacture, and capable of being widely applied to assembling of sliding doors and windows.

Description

technical field [0001] The invention relates to a slide rail wheel set for sliding doors and windows. Background technique [0002] Sliding doors and windows generally all need to be equipped with a slide rail wheel set on the lower frame of the door leaf or window sash, so that the door leaf or window sash can stand upright on the slide rail and slide along the slide rail. The structure of the slide rail wheel set can be referred to figure 1 and figure 2 . Such as figure 1 and figure 2 As shown, the slide rail wheel set includes a shell 1 stamped from sheet metal, which is a rectangular box with an opening downward as a whole, and the first connecting hole is opened at the right end of the shell 1; the shape of a roller frame 2 is also open. Downward rectangular box body, the second connection hole opened at the right end of the roller frame 2, several rollers 3 are installed on the roller frame 2 through roller shafts; the roller frame 2 is inserted into the shell 1...
