FIELD: locking equipment. SUBSTANCE: door locking device has drive plate mounted on pin for restricted motion and provided with openings for receiving cross bars positioned in guiding sleeves and recess for receiving locking member of lock. Recess has working surface positioned at an angle to nonworking surface. Working surface of recess cooperates with that of locking member. Nonworking surface of drive plate adjacent to working surface is positioned in spaced relation to working surface of locking member. Working surface of drive plate is aligned with radial line extending through axis or is positioned in parallel with radial line extending through axis and is spaced from axis by distance not exceeding 50% of distance between pin and opening axis. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 6 cl, 7 dwg
