Day and night curtain double-track double-control associated limiter
The invention discloses a day and night curtain double-track double-control associated limiter which comprises a limiting seat, a descending stop block, an ascending stop block, a main screw rod, a main gear, an auxiliary screw rod and an auxiliary gear, the main gear is meshed with the auxiliary gear, a descending stop bulge is arranged on the main screw rod, an ascending stop bulge and a synchronous linkage bulge are arranged on the auxiliary screw rod, and the synchronous linkage bulge is meshed with the descending stop block. A synchronous linkage shifting block is arranged on the end face of the auxiliary gear and shifts the synchronous linkage protrusion, so that the auxiliary mandrel rotates synchronously along with the main mandrel. By the adoption of the technical scheme, double-rail double-control relevance limiting control is achieved, when the curtain body bottom rail moves upwards to support the curtain body top rail and a lifting rope of the curtain body top rail lifting winder loses the gravity of the curtain body top rail, double rails are synchronously linked through the limiting device, and the curtain body top rail lifting winder can lift the curtain body top rail. Therefore, the problems of loosening and disordered rope arrangement of the lifting rope of the top rail lifting winder are thoroughly solved, and the day and night curtain runs more safely and reliably.
本发明公开了一种日夜帘双轨双控关联型限位器，包括限位座、下行止位挡块、上行止位挡块、主螺杆、主齿轮、辅助螺杆和辅助齿轮，主齿轮与辅助齿轮相啮合，主螺杆上设有下行止位凸起，辅助螺杆上设有上行止位凸起和同步联动凸起，辅助齿轮的端面上设有同步联动拨块，同步联动拨块拨动同步联动凸起，使辅助芯轴跟随主芯轴同步转动。本专利的限位器采用了上述的技术方案，实现了双轨双控的关联性限位控制，当帘体底轨上移到将帘体顶轨撑起，当帘体顶轨升降卷线器的提绳失去帘体顶轨的重力时，通过限位器使双轨实现同步联动，从而彻底解决了顶轨升降卷线器的提绳发生松弛和排绳混乱的问题，使日夜帘的运行更加安全可靠。
