Embodiment Construction
[0010] Such as Figure 1-2 As shown, a pulley-type upper attachment of a sliding window includes an attachment seat 2 that can be embedded in the upper frame 1 of the door and window sash, and the attachment seat 2 is provided with an upper frame 3 that can accommodate the door and window frame. The guide groove 21 into which the guide strip 31 is inserted. In the present invention, the gear holder 2 is respectively equipped with rollers 4 clamped on both sides of the guide strip 31 and rolling along the length direction of the guide strip 31 on both sides of the guide groove 21 . Because the upper attached gear of the present invention has installed roller 4 additionally, utilizes roller 4 to clamp the both sides of guide bar 31, the sliding fit of traditionally attached gear and guide bar 31 has become rolling fit, has greatly reduced the upper attached gear and the two sides of guide bar 31. The frictional resistance between the guide strips 31 makes it more superior in per...

The invention discloses a rolling wheel type upper guide piece of a sliding window. The upper guide piece comprises a guide piece base capable of being embedded in an upper sash frame of a door and window sash, the guide piece base is provided with a guide groove capable of allowing a guide strip of an upper frame of a door and window frame to insert therein, the guide piece base is provided with rolling wheels on the two sides of the guide groove respectively, and the rolling wheels are clamped on the two sides of the guide strip and roll in the length direction of the guide strip. Because the two sides of the guide groove of the upper guide piece of the sliding window are provided with the rolling wheels, the guide strip is clamped by the rolling wheels on the two sides, and accordingly friction between the upper guide piece and the guide strip is maintained as rolling friction, friction resistance between the upper guide piece and the guide strip is greatly reduced, friction loss between the upper guide piece and the guide strip is reduced, and the service life of the upper guide piece is effectively prolonged.
Description
technical field [0001] The invention relates to the technical field of sliding windows, in particular to an upper attachment of a movable sash of a sliding window. Background technique [0002] In the sliding window, the movable sash is embedded in the groove rails of the upper frame and the lower frame of the window frame to slide. Usually, the groove track of the lower frame of the window frame has an upwardly convex guide rail, and the U-shaped sheave is installed on the lower frame of the sash, and the sheave supports the sash to slide on the guide rail. In order to prevent the upper end of the window sash from swinging back and forth, some window frame upper frames will form a downwardly convex guide strip. Correspondingly, an upper bracket is installed on the upper frame of the window sash, and the upper bracket is provided with a U-shaped guide groove, and the guide strip is inserted into the guide groove. Inside. Because there is sliding friction between the guide ...
