The invention discloses a semi-enclosed pulley component shell assembly which is sheathed outside the pulley component moving along the track and used for the outer sealing of the pulley component; the main body of the shell of the pulley component is a shell with an inner cavity, and can also include a shell cover plate; the top of the shell of the pulley component is an open shape; and a through-type opening with a similar track section is arranged at the bottom of the shell of the pulley component; A sealing structure and a sealing strip are arranged at the lip of the through-type notch, and at least one side end face of the outer shell of the pulley component is provided with a sealing shield. A relatively closed space is formed between the shell cover plate (or the fixed surface of the pulley), the shell of the pulley component, the sealing strip, the sealing shield, the track surface or the profile surface; the pulley components are installed in the relatively closed cavity and move along the track. The invention can effectively solve the problems caused by the insufficient sealing of the pulley parts due to the naked reasons, such as waterproof, dust-proof, heat preservation, etc. Meanwhile, the closed space composed of multiple components can also reduce the noise generated by the movement of the pulley parts.

一种半封闭式滑轮部件外壳组件
本专利技术公开了一种包套在沿轨道运动的滑轮部件的外部,用于增强滑轮部件外部密封的半密闭式滑轮部件外壳组件,尤其是:用于建筑领域推拉门窗轨道型材上的一种半封闭式滑轮部件外壳组件。
技术介绍
现有的推拉门窗,由型材拼接成型的上下左右四边框组成:主要有水平方向的上滑道、下滑道,竖直方向的边封组成的门窗框;由水平方向的上横、下横,竖直方向的光企、勾企以及门窗板如玻璃构成的门窗扇;门窗扇放置在门窗框的上滑道、下滑道之间。滑轮部件在门窗扇下横的滑轮槽中,承载着门窗扇可在下滑道的轨道上滑动,形成推拉门窗。推拉门窗以其重量轻、开启关闭方便、面积大视野广、不占室内外空间、抗风压能力强,而深受用户喜爱,在门窗领域中占有重要的地位。但推拉门窗因传统结构上的原因,难以全面采用密封胶条等高效密封材料进行密封,主要困难在于推拉门窗在水平方向的上横对上滑道、下横对下滑道的的密封问题,由于密封性不够,进而导致防风保温、隔音防尘方面性能偏低,使用体验上的欠缺妨碍了其进一步的发展。为克服推拉型门窗在密封结构上的不足,众多科技工作人员作出了不懈的努力来提高密封性方面的性能 ...
