FIELD: construction.SUBSTANCE: invention relates to the field of construction, namely, to structures of screening or protective devices for openings. The tubular drive for actuation of a wound element in a building, comprises a geared engine in a pipe with a longitudinal axis and an output shaft at the first end of the pipe, a fixed point of two parts at the second end of the pipe, at the same time the fixed point comprises the first part, at least partially arranged outside the pipe, and the second part assembled in the pipe. The first part comprises at least one axial continuation of the torque and weight perception, at the same time the specified continuation of torque and weight perception is made as capable of entering into at least one groove of the second part and is stopped in the reciprocal movement along the longitudinal axis relative to the pipe of the drive with the help of the first stopping facility.EFFECT: invention will make it possible to simplify drive installation.11 cl, 8 dwg |
