Locking device for detachable connection of two components has threaded bolt with locking plate release pin, pressed towards plate by retainer spring with lower return force than support spring

摘要

The device consists of a threaded bolt (6) fitted into apertures (3,4) in the components (1,2), and a seat element (7) for a locking mechanism. This has two securing plates, one (9) of which is detached from the other one (8) by a release pin (11) integrated in the bolt. The pin is pressed towards the first plate, which is located on the side away from the bolt, by a retainer spring (12). The return force of the spring is lower than that of a support spring (10) acting in direction of the bolt. The axial movement of the first plate is limited, so that the plates are disconnected when in end position. The plates are supported on each other via an intermediate spring (13).
