Rotary self-locking start structure of door lock

Abstract

A rotary self-locking start structure of a door lock comprises a panel, a counter locking rotary knob, a first elastic part, a fixing base, a counter locking device and a square strip; the panel is provided with a movable through hole, and at least one limiting boss is arranged on the inner wall of the movable through hole; the counter locking rotary knob comprises a rotary body; a clutch cavity is arranged in the rotary body, at least two segments of stop skirt edges are arranged at the outer edge of the rotary body, and a clutch notch is formed between every two adjacent segments of block skirts; the fixing base and the clutch cavity are arranged face to face, and when the counter locking rotary knob is pressed, the fixing base is sleeved with the clutch cavity; one end of the first elastic part abuts against the bottom end of the clutch cavity, and the other end of the elastic part abuts against the bottom end of the fixing base; the counter locking device is installed on the paneland used for achieving counter locking of the door lock; and the square strip penetrates through the counter locking device to be connected with the fixing base. According to the rotary self-locking start structure, counter locking caused by misoperation of a child and the like can be effectively avoided, and misoperation preventing can be achieved.
