Abstract

According to a child safety seat with the rotating mechanism provided by the present invention, the seat body is driven to rotate 360 degrees through the toothed ring and the screw rod. The screw rod is more labor-saving and has a simpler structure. The turntable is fixed relative to the seat body. The locking member is arranged at a bottom of the seat body, and the positioning slot is arranged on the toothed ring, to fix the turntable and the toothed ring. By the arrangement of the plurality of positioning slots on the toothed ring and the arrangement of an unlocking switch configured to unlock the locking member and the positioning slots, the seat body can be manually rotated through the turntable, which is faster. By the arrangement of the sensor to sense whether the seat body is locked, the safety of use is improved.
