Abstract

The invention provides a knob device capable of bidirectionally rotating and automatically resetting for a lock. The knob device comprises an upper cover and a base, wherein the base is provided with a knob shifting block synchronously rotating with a knob rotating shaft, and a rotating shaft plug-in mounting hole for mounting the knob rotating shaft is formed in a square shaft; the knob shifting block comprises the square shaft which is arranged vertically; the base is also provided with at least one knob shifting block locating block; a sliding chute is formed in the base, and the knob shifting block locating block is arranged in the sliding chute; a reset spring is arranged in the sliding chute and is compressed between the sliding chute and the knob shifting block locating block, so that the knob shifting block locating block pushes and presses the side of the square shaft; and the knob shifting block locating block can elastically slide back and forth in the sliding chute along with the rotation of the knob shifting block. The knob device provided by the invention has the advantages of resetting accuracy, large rotation angle, resetting automation and the like.

Description

technical field [0001] The invention relates to a lock device; in particular, it is a bidirectionally rotatable and automatic reset knob device used in door locks. Background technique [0002] Most existing knob devices in door locks can only achieve an effective rotation range of 90°, that is, when unlocking, turn the knob 90° clockwise or counterclockwise, and lock it by turning the knob counterclockwise 90° to reset Achieved. The rotation angle is limited, and the user is easy to over-twist to damage the internal structure of the knob device. On the other hand, the structure of most knob devices has the problem of insufficient stability. Its structure is complex, the resistance to be overcome when twisting is relatively large, and the rebound force of reset after twisting is also relatively large. Inconvenient to use also shortens the service life of the knob device. [0003] For this reason, it is necessary to design a knob device with a simpler structure, more stabl...
