Bar is made as extension of rotary unit rod included in secrecy mechanism. Bar is provided with thread made on bar end and screwed into nut restricted from rotation relatively the body. During door locking nut translates towards lock body. Locking operation terminates as nut end surface touches opposite lock body surface. Secrecy mechanism is installed in lock. Secrecy mechanism has tubular key with cylindrical arm. Axle projecting beyond arm is installed in axial orifice of the key so that the axle is spaced from orifice edge and restricted from axial movement. Projected axle end is provided with radial orifice. ^ EFFECT: increased resistance to breakage-in. ^ 2 cl, 2 dwg |
