Spiral type reverse clutch assembly
The invention provides a spiral type reverse clutch assembly. A radial blind hole is formed in the outer circumferential surface of a square steel sleeve, a square steel hole is formed in the end surface of the square steel sleeve, and a protrusive spiral structure is arranged on the outer circumferential surface; a step counter bored hole for installing the square steel sleeve is formed in the end surface of an internal handle rotating piece, a radial lifting pin hole is formed in the outer circumferential surface of the internal handle rotating piece, and the lifting pin hole is communicated with the step counter bored hole; an internal handle rotating piece spiral structure matched with the spiral structure of the square steel sleeve is arranged on the step surface of the step counter bored hole. The spiral type reverse clutch assembly is located on an indoor back panel, even though a front panel is broken and disassembled, a door lock cannot be unlocked; in addition, the spiral type reverse clutch assembly can be rotated unidirectionally, when the spiral type reverse clutch assembly is rotated reversely, the spiral surfaces of the internal handle rotating piece and the square steel sleeve enable the square steel sleeve and the internal handle rotating piece to be separated, the internal handle rotating piece cannot be rotated depending on friction force, the safety is high, and fast locking can be achieved both indoors and outdoors according to the design.
