Pulley mechanism and heavy lifting door and window
The invention discloses a pulley mechanism and a heavy lifting door/window, the heavy lifting door/window comprises a door/window main body and a pulley mechanism, the pulley mechanism is connected to the door/window main body and used for supporting the door/window main body, and the pulley mechanism is configured at the non-end part of the heavy lifting door/window in the horizontal direction; the pulley mechanism comprises a connecting piece, a baffle, an elastic piece and a pulley assembly, one end of the elastic piece is connected to the connecting piece, the other end of the elastic piece is connected to the pulley assembly, and the sliding rail for installing the pulley mechanism and the sectional material of the door and window body have inevitable size errors in the actual use process. The elastic piece can stretch out and draw back freely, the pressure applied to the pulley assembly by the elastic piece does not exceed the maximum bearing capacity of the pulley all the time, under the action of the elastic piece, damage cannot be caused when the stress space height of the pulley mechanism changes, and the service life of the pulley mechanism and the heavy lifting door and window is effectively prolonged.
本发明公开了一种滑轮机构及重型提升门窗，重型提升门窗包括门窗主体和滑轮机构，滑轮机构连接于门窗主体，用于支撑门窗主体，该滑轮机构被配置在重型提升门窗在水平方向的非端部；滑轮机构包括连接件、挡板、弹性件和滑轮组件，弹性件的一端连接于连接件，另一端连接于滑轮组件，安装滑轮机构的滑轨及门窗主体的型材在实际使用过程中存在无法避免的尺寸误差，当滑轮机构的受力高度发生变化时，弹性件能自由伸缩，弹性件给到滑轮组件的压力始终不超出滑轮的最大承受力，在弹性件作用下，本发明中的滑轮机构的受力空间高度发生变化时也不会造成损坏，有效地延长了滑轮机构及重型提升门窗的使用寿命。
