The present invention relates to the field of consumer electronics. Provided is a concealed bolt device installed inside a frame for fixedly connection to the frame. The concealed bolt device comprises an driving part (2), a bolt (3), a nut (5) and a chip; the driving part is fixedly connected to one casing of the frame; the driving part (2) is connected to the bolt (3); the nut (5) is fixedly connected to the other casing of the frame and fits with the bolt (3); the chip controls the motion of the driving part, and the driving part (2) drives the bolt (3) to move relative to the nut (5) so as to realize engagement or separation between the bolt (3) and the nut (5). The concealed bolt device employs a concealed bolt structure, thus realizing internal linkage and locking attachment with all structures being hidden from view, and realizing repeated assembling and disassembling without changing or replacing any component; and activating a driving part via a chip prevents a unit from being disassembled by a nonprofessional, thus ensuring safety. |
