The invention discloses a strip lock anti-falling mechanism. The strip lock anti-falling mechanism comprises a shifting strip, a shifting fork, an anti-falling hook and a hook groove piece; an upper limiting plate is arranged at the position, above the top of the shifting strip, of the upper portion of the shifting fork; a lower limiting plate is arranged at the lower portion of the shifting fork; a movable groove is formed in the position, corresponding to the lower limiting plate, of the back face of the shifting strip; a shifting fork downward pushing wall is arranged at the position, above the lower limiting plate, of the top of the movable groove; the anti-falling hook is pivoted and mounted on the back surface of the shifting strip and is supported below the upper limiting plate; the hook groove piece is arranged on the periphery of the shifting fork and is provided with a hook groove corresponding to the anti-falling hook; in a locking state, the anti-falling hook is hooked on the hook groove and is supported below the upper limiting plate to prevent the shifting fork from falling; during unlocking, the shifting strip is pulled downwards to drive the anti-falling hook to rotate to be separated from the hook groove and jack up the shifting fork, and the shifting fork downward pushing wall pushes the shifting fork to drive the anti-falling hook and the shifting fork to move downwards synchronously when the shifting strip is shifted downwards to achieve unlocking. and locking is facilitated, the shifting fork can be prevented from falling during locking, unlocking is facilitated, meanwhile, simplicity and ingeniousness are achieved, actual production and machining are facilitated, assembling is convenient, and the production cost is controlled.
本发明公开了一种条锁防坠机构，包括拨动条、拨叉、防坠钩和钩槽件，拨叉上部位于拨动条的顶部上方设有上限位板，拨叉下部设有下限位板，拨动条背面对应下限位板设有活动槽，活动槽顶部位于下限位板的上方设有拨叉下推壁，防坠钩枢接安装于拨动条背面并支撑于上限位板的下方，钩槽件设于拨叉外围并对应防坠钩设有钩槽；上锁状态，防坠钩勾在钩槽上并支撑于上限位板下方对拨叉防坠；解锁时，向下拉动拨动条带动防坠钩转动脱离钩槽并将拨叉顶起，由拨叉下推壁推动拨叉在拨动条下拨时带动防坠钩及拨叉同步向下移动实现解锁；方便上锁、上锁时对拨叉起到防坠及方便解锁的同时更为简单巧妙、更利于实际生产加工、装配的便利及控制生产成本。
