LOCKING DEVICE FOR AN AXIALY MOVING PIN

摘要

Locking device (20) includes housing (21) with bore (22) for receiving end portion (12) of a pin. With end portion (12) fully inserted in housing (21), body portion (25) of rotating locking member (23) can interact with circumferential recess (13) of end portion (12) to prevent longitudinal or axial movement of the pin relative to housing (21). When head portion (24) of member (23) is rotated through half a turn from the locking position, an identation or notch in portion (25) is aligned with bore (22) and end portion (12) can be withdrawn from bore (22). Member (23) can be rotated by way of a key or other suitable tool. Locking device (20) can be used to secure the adjusting pin for telescopic members such as bracing used in building construction or a tow bar on a vehicle.
