A nut lock or locking cap secures a nut on a bolt so that the nut cannot loosen itself and so that the nut cannot fall off the bolt. For this purpose the nut lock has a first ring section that at least partially surrounds the bolt and a second ring section that at least partially surrounds the nut. The two ring sections are interconnected by a radially extending flange, whereby the first ring section has a smaller diameter than the diameter of the second ring section. The first ring section has at least one through-hole that can be aligned with a cross-bore in the bolt for the insertion of a locking pin. The second ring section has radially inwardly facing profiled surfaces that enter into a form-locking, force-transmitting connection with the outer profile of the nut.

Device for locking a nut on a bolt

An actuation device for a slat, a rail for guiding and moving the slat into and out of an aircraft wing has the slat pivoted on the rail in a particular point (8); a thrust rod has one end hinged to the slat and a drive crank is connected to a second end of the thrust rod; a lever assembly connects the rail additionally to the slat at points on the rail and the slat different from the particular point and for pivoting and steering the slat relative to the particular point, for holding the rear end of the slat against the wing in a first protraction range and opening a gap upon further protraction.
