Description

一种滑车机构a pulley mechanism 技术领域technical field
本实用新型涉及开合窗帘技术领域,具体地,涉及一种滑车机构。The utility model relates to the technical field of opening and closing curtains, in particular to a pulley mechanism.
背景技术Background technique
开合窗帘传动装置中,具有主驱动机构及从驱动机构,其中主驱动机构中具有主滑轨、主传动带及主滑车机构,主传动带固定连接有主滑车机构,进而可以通过主传动带带动主滑车机构沿着主滑轨滑动,从而进一步带动主帘的移动,从驱动机构具有副滑轨、从传动带及从滑车机构,当主驱动机构运动的时候,可以间接带动从传动带移动,通过从传动带带动从滑车机构沿着副滑轨滑动,从而进一步带动副帘的移动。The opening and closing curtain transmission device has a main driving mechanism and a secondary driving mechanism, wherein the main driving mechanism has a main sliding rail, a main transmission belt and a main pulley mechanism, and the main transmission belt is fixedly connected with the main pulley mechanism, which can drive the main pulley through the main transmission belt. The mechanism slides along the main sliding rail, thereby further driving the movement of the main curtain. The secondary driving mechanism has a secondary sliding rail, a secondary transmission belt and a secondary pulley mechanism. When the main driving mechanism moves, it can indirectly drive the secondary transmission belt to move. The pulley mechanism slides along the auxiliary sliding rail, thereby further driving the movement of the auxiliary curtain.
换句话说,传统的开合窗帘传动装置中,主滑车机构及从滑车机构都是分别固定连接在主传动带及从传动带上,而当窗户的尺寸发生变化,需要调节主滑轨或副滑轨的相对长度,以使开合窗帘传动装置适应窗户尺寸的变化,调节主滑轨或副滑轨的相对长度后,需要同时调节主滑车机构或从滑车机构在主传动带或从传动带上的位置,使得主滑车机构或者从滑车机构拉动主帘或副帘的幅度同样满足窗户尺寸要求。由于传统的开合窗帘传动装置中,主滑车机构及从滑车机构都是分别固定连接在主传动带及从传动带上,此时只能将主滑车机构或者从滑车机构机构从开合窗帘传动装置中整体拆卸出来,再分别固定在传动带合适的位置,调节不便。In other words, in the traditional opening and closing curtain transmission device, the main pulley mechanism and the slave pulley mechanism are fixedly connected to the main drive belt and the slave drive belt respectively, and when the size of the window changes, it is necessary to adjust the main slide rail or auxiliary slide rail. In order to make the opening and closing curtain transmission device adapt to the change of window size, after adjusting the relative length of the main sliding rail or the auxiliary sliding rail, it is necessary to adjust the position of the main pulley mechanism or the slave pulley mechanism on the main drive belt or the slave drive belt at the same time. The range of pulling the main curtain or the auxiliary curtain from the main pulley mechanism or the pulley mechanism can also meet the window size requirements. Since in the traditional opening and closing curtain transmission device, the main pulley mechanism and the slave pulley mechanism are fixedly connected to the main transmission belt and the slave transmission belt, respectively. At this time, only the main pulley mechanism or the slave pulley mechanism can be removed from the opening and closing curtain transmission device It is disassembled as a whole, and then fixed to the appropriate position of the transmission belt, which is inconvenient to adjust.
