Title: SECURING DEVICE FOR ATTACHING TO A LEDGE OF AN ACTUATING DRIVE HOUSING HAVING A REGULAR, CONVEX, POLYGONAL OUTER CONTOUR, WHICH LEDGE COAXIALLY SURROUNDS AN ACTUATION CONNECTION
Abstract:
The invention relates to a device for securing an actuating drive (1) attached to a tube outer face of a ventilation tube against rotation during operation. The actuating drive has an actuator for driving an actuation connection about an actuation axis. The actuation connection interacts with a flap arranged in the ventilation tube to set a gaseous volumetric flow, in particular for the heating, ventilation, or air conditioning of a building. The actuating drive comprises a housing (2) having a ledge (3), which is formed on a bottom side of the housing and surrounds the actuation connection coaxially to the actuation axis. The housing bottom side lies opposite the tube outer face. The device has a fastening part for fastening to the tube outer face and a fork-shaped receptacle formed at the remote end of the fastening part. Said receptacle is geometrically coordinated with a radial outer face of the housing ledge in such a way that the receptacle, after lateral sliding onto the outer face of the ledge, fixes said ledge and thus the actuating drive, by means of interlocking connection, against rotation about the actuation axis.
