Abstract
The utility model discloses a safety lock and the key. The safety lock comprises a lock plug; a metal sleeve which is provided with a top surface is arranged outside the lock plug; a permeation groove is opened from the middle part to the side wall of the metal sleeve on the top surface; the permeation groove extends downwards for a certain distance along the side wall of the metal sleeve and axially to the metal sleeve, thus the permeation groove takes the shape of L on the side wall of the metal sleeve; the permeation groove is opened with an expansion hole at the end part on the metal sleeve and the diameter of the expansion hole is larger than the width of the permeation groove; the top surface of the lock plug is not higher than the lowest points of the permeation groove and the expansion hole. The key used for the safety lock is provided with a connection rod, one end of which is connected with a holding part of the key and the other end is connected with the cylindrical opening end of the key; the outer diameter of the cylindrical opening end is smaller than the diameter of the expansion hole on the safety lock but larger than the width of the permeation groove; the diameter of the connection rod is smaller than the width of the permeation groove.
Description
Technical field
