The invention relates to a self-locking device which comprises a first abutting plate, a second abutting plate, a spring arranged between the first abutting plate and the second abutting plate, and a rail ditch with one end connected to the first abutting plate through a shaft. One side of the second abutting plate extends outwards to form a rail block matched with a rail hook, and the other side of the second abutting plate extends outwards to form a first slide block with a first inclined face at the free end. The self-locking device further comprises a locking block matched with the first slide block. A guide groove connected with the other end of the rail hook in a sliding mode is formed in the rail block. By means of the self-locking device, the defect that an existing roller shutter window and door can not be automatically locked is overcome, and the automatic locking is completely achieved; the self-locking device is simple in structure, easy to produce, low in cost, capable of being produced on a large scale and remarkable in social and economic benefit; the self-locking device is compact in structure, a beam and a bottom frame of the self-locking device firmly abut against each other, and gaps can be effectively avoided; the self-locking device is easy and convenient to use and can be easily accepted by consumers, and the user experience is high.
