Structure for fixing a device on a supporting channel bar

摘要

Means for fixing a device on supporting a channel bar comprise a leg (5), a fixing component (2) and a compression spring (3). The fixing component has a rod (12) and a body (11) which slide in a longitudinal guide (24) in the base (1) of a housing for said device to be fixed on the bar. Two recesses (9, 10) are provided in the base. The compression spring is installed in a partially compressed condition in the first recess (9) and the rod (12) passes through it, said rod forming shoulders (19) with the body. The end of the rod (12) is fitted with a pin (4). The fixing component has two hooks (13, 14) and a guide (15) which co-operates with a groove (27) of the base to make the fixing component captive.
