FIELD: construction.SUBSTANCE: cylindrical lock comprises a body, a cam, a groove arranged in the front part of the body, an outer core and an inner core fixed on the body with the help of rings. In cores there is a hole for key placement. In the body and in the inner core there are main holes arranged coaxially, where locking bars are placed, springs, body bars and core bars. In the front part of the body and the front part of the outer core there are inserts of tempered metal are tightly installed. The cam is installed freely between outer and inner cores of identical length. In the outer core there are also main holes, which are coaxial with appropriate main holes arranged in the body, where locking bars, springs, body bars and core bars are installed. Along the entire length of the main holes in the outer core in the same plane with a groove in the body there is an additional slot to form a common slot in order to weaken cross section, in which there is a plastic holder closing the specified common slot, in which there is a spring, a body bar and a core bar arranged. In the additional slot of the outer core there are radial holes drilled, in which there are steel balls installed. Opposite to the slot and opposite to the additional slot arranged accordingly in the body and the outer body there are additional inserts of tempered metal tightly installed in appropriate coaxial holes drilled in the body and the outer core and arranged in staggered order relative to the main holes. In planes perpendicular to the plane of the key hole, in the outer core and in the inner core there are additional holes, where additional core bard are arranged. Inside the body there are longitudinal grooves with a shape corresponding to the shape of the additional core bars.EFFECT: increased level of protection against break-in.4 cl, 8 dwg |
