Abstract

The invention relates to ((means to protect protected areas and improves reliability and secrecy of locking. As a seal, a control tape 6 is applied, which is fixed as a roll in the case 1 of a lock with a bow 4 and separated from the perforated sheet of the tear-off book, identified by an eight-digit number A knife 18, which is fixed in the housing, interacts with the tape 6. When the key is turned, the sleeve 8 rotates with the cylinder mechanism 2, on which the charging end of the control tape 6 is fixed. Thus, any turning the key is inevitably accompanied by cutting the tape 6, which makes it possible to unambiguously determine whether the action was malicious when opening the lock.The locking member 25 is actuated by a spring 26 placed at the slot, which is made on the surface of the sleeve 8. 1 cpf. 13 silt

Claims (2)

Claim 1. A control lock comprising a housing with a viewing window, a locking key, cylinder key located in the housing with the possibility of longitudinal movement. A mechanism associated with the locking body and having a leash, a control unit including a control unit located on a rack parallel to the axis of the cylinder mechanism. a control tape, a sleeve with a slot and a destructive element for placement in the slot of the sleeve and interact with the control tape, characterized in that, in order to increase the reliability and secrecy of locking, it is equipped with a means for moving the control tape, including an elastic plate connected to the lead of the cylinder mechanism with puklevki and placed on the casing with the cover of the viewing window by a casing, while the sleeve of the control unit is made in the form of a glass, mounted for rotation to accommodate the coax tape Along with the cylinder mechanism with its bottom located on the side opposite to the key input and with a gap for placing the elastic plate, it has holes on the inner surface of the bottom for the placement of pupples, and on the outer surface there is an ellipsoid groove and a cut made along the major axis an ellipse, and the cylinder mechanism is connected to the locking body by means of a pin fixed at one end to the locking body with the possibility of moving its free end along the ellipsoid groove, and crackers placed in the slot of the bushings kits and mutually spring-loaded to contact the pin in the closed position and to ensure that the locking element is pulled out of this position, and to prevent the control tape from returning and to visually observe its position, the control unit includes a ratchet mounted on the outer surface of the sleeve from the key input side and the spring-loaded stem interacting with it, while the housing has grooves for accommodating the stem and rigidly installing the destructive element. 2. Castle pop. 1, characterized in that a transverse slot is made in the housing on the key input side to accommodate an additional control element. fs / 2.6 ta.7 phage. 9 of FIG. 12
