Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a window pulley. Background Art

[0002] Windows are a fixture in nearly every home, and installing a window frame is essential. At the bottom of the frame is a sash groove, which allows the window sash to slide left and right. Window sash grooves easily accumulate dust, making them essential for routine cleaning. Currently, manual cleaning is common, but due to the narrowness of the sash groove and the obstruction of the window sash, dust collection within the sash groove is difficult, making cleaning more challenging. Therefore, it became necessary to develop a window pulley that could collect dust within the sash groove. Utility Model Content

The front panel and the rear panel are arranged relative to each other in the front and rear directions. The front panel and the rear panel are both provided with a guide hole 11. The guide hole 11 is arranged upward and tilted from the inside to the outside along the moving direction of the pulley 40. Therefore, the pulley 40 can be dynamically adjusted along the direction of the guide hole 11 according to the actual operating conditions, so that the window pulley 100 can run more smoothly. The side panels connect the front panel and the rear panel. There are two side panels, and the two side panels are respectively arranged on the left and right sides of the front panel and the rear panel. One of the side panels is provided with a snap-on strip 12 adapted to the window side frame, and the snap-on strip 12 is provided with a mounting hole 13; the other side panel is provided with a fixing hole 14. The window pulley 100 can be fixed to the bottom of the window sash through the arrangement of the mounting hole 13 and the fixing hole 14, which is more convenient for users to install.

[0037] See also Figure 2 The inner shell 20 is arranged in a frame-shaped structure, and the inner shell 20 includes a front plate, a back plate and a side plate. The front plate and the back plate are arranged opposite to each other front and back, and the side plate is arranged between the front plate and the back plate. A hinge hole 21 is provided on the front plate and the back plate, and the end of the hinge shaft 30 passes through the hinge hole 21 and extends into the guide hole 11. A lower slot 22 is provided at the lower end of the front plate and the back plate.

The scraper plate 50 includes a main body 51 and an abutting portion 52 connected to the main body 51. The abutting portion 52 is always in abutment with the window frame slide groove. The main body 51 is tilted outward along the moving direction of the pulley 40. The angle between the main body 51 and the horizontal plane is 25° to 35°. In this way, when the scraper plate 50 moves outward, most of the dust can be shoveled together and gathered. The scraper plate 50 is provided with a clearance groove 53 adapted to the window frame guide rail. The clearance groove 53 extends from the main body 51 to the abutting portion 52. The material of the scraper plate 50 is silicone.
