Anti-falling locking device
The invention provides an anti-falling locking device. The anti-falling locking device comprises a disc spring cylinder, a door frame, an upper wedge-shaped block and a lower wedge-shaped block. The cylinder body end of the disc spring cylinder is hinged with the door frame; the upper wedge-shaped block is detachably installed at the cylinder body end of the disc spring cylinder, and the lower wedge-shaped block is hung on the door frame through an extension spring. The upper wedge-shaped block is provided with a downward wedge-shaped surface, the lower wedge-shaped block is provided with an upward wedge-shaped surface, and the downward wedge-shaped surface of the upper wedge-shaped block is in contact with the upward wedge-shaped surface of the lower wedge-shaped block; when the part to be prevented from falling accidentally falls, the lower wedge-shaped block moves upwards and horizontally relative to the upper wedge-shaped block, the anti-falling locking device can be in a locked state, and the part to be prevented from falling continuously is prevented from falling. The anti-falling locking device is compact in structure, safe, reliable and easy to operate.
本发明提供了一种防坠落锁紧装置，其包括碟簧缸、门框、上楔形块、下楔形块；所述碟簧缸的缸体端与所述门框铰接；所述上楔形块可拆卸的安装在所述碟簧缸的缸体端上，所述下楔形块通过拉伸弹簧吊装在所述门框上；所述上楔形块具有向下的楔形面，所述下楔形块具有向上的楔形面，且所述上楔形块向下的楔形面与所述下楔形块向上的楔形面接触；当待防坠落件意外坠落时，下楔形块相对于上楔形块向上移动和水平移动，可让防坠落锁紧装置处于锁定状态，阻止待防坠落件继续坠落。本发明的防坠落锁紧装置结构紧凑、安全可靠、易于操作。
