Interlockable gear-push mechanical anti-theft lock
The invention discloses an interlockable gear-push mechanical anti-theft lock. A rear cylinder and a front cylinder are thoroughly disconnected; a connecting member is hidden in an invisible hole; an expanding sheet locks the front cylinder; the front cylinder is internally provided with a cranked channel, a special keyhole and the invisible hole in which the connecting member is disposed; the connecting member is disconnected with the rear cylinder; the front of the rear cylinder is provided with a connecting hole, and a connecting bolt fixed to the rear of the rear cylinder penetrates a through hole; a slider is mounted in a slide channel and a cranked channel; the slider and a sliding spring are mounted in the slide channel; the expanding end of the expanding sheet locks the front cylinder in a locking channel; a gear-push device and a connecting locking device lock the front cylinder. The lock has the functions of mechanical interlocking, invisibility and invisible connection of the front and rear cylinders; a thief can never open an internal supporting locking member and rotate the rear cylinder; even after the internal supporting locking member and the connecting member are damaged by forcible means, only the front cylinder is rotatable, the rear cylinder is unable to be rotated, and thus theft is thoroughly prevented.
