PVC (polyvinyl chloride) plastic-wood ventilating window
The invention provides a PVC plastic-wood ventilated window which is characterized in that a transmission mechanism used for driving a plurality of fan blades to synchronously rotate is arranged in one vertical frame, the fan blades are rotationally connected and assembled between the two vertical frames, and horizontal frames are assembled and connected to the tops and the bottoms of the two vertical frames; compared with the prior art, when the included angle between the inclined face and the vertical face is 18.43 degrees, component force of force in the horizontal direction can be weakened, the rotating force of the fan blades is smaller due to the fact that the fan blades attempt to receive, and therefore the fan blades are not prone to rotating due to the design of the included angle of 18.43 degrees, the pushing rate is reduced, and when the fan blades are driven by external force to rotate, the fan blades are not prone to rotating. At the moment, the directions of the forces are just opposite, and a labor-saving pulley block formed by the large pulley, the small pulley and the fixed pulley is converted into a labor-consuming pulley block, so that the fan blades are not easy to push away, the probability that the fan blades are pushed away is reduced, the pushing-away rate of the fan blades is reduced, and the pushing-away rate is further reduced.
本发明提供了一种PVC塑木透气窗，一个竖直边框的内部设有用于带动若干扇叶同步转动的传动机构，若干扇叶转动连接组装在两个竖直边框之间，两个竖直边框的顶部和底部均组装连接有水平边框；本发明与现有技术相比，当倾斜面与竖直面的夹角为18.43°时，力在水平方向上的分力会被削弱，扇叶收到的试图使其转动的力更小，因此，18.43°的夹角设计使得扇叶更不易被转动，从而减低推开率，当扇叶被外力驱动进行转动时，此时力的方向刚好相反，此时的大滑轮、小滑轮和定滑轮构成省力的滑轮组转换成了费力滑轮组，使扇叶不易被推开，从而减少了扇叶被推开的几率，减少了扇叶的推开率，进一步减低推开率。
