Road shaft cover bolting system houses spring-retractable bolt in system housing to engage bottom hole and firmly joined to underside bar held bolted by angled locking ramps.

摘要

A hole (13) in the bottom wall (12) of the bolting system housing (10) is engaged by a bolt (14) as firmly joined to a bar (15). A spring (17) in the housing (10) retracts the bolt (14) axially to pre-tension the bar (15) onto the housing bottom wall (12). Co-operating locking elements on housing (10) and bar (15) releasably lock this (15) in the bolting position. The bolt itself (14) can be pressed inwards and twisted so the bar (15) engages a blocking element as it enters the bolting position. The locking elements are designed as ramps set at 45 deg and molded to housing wall (12) and bar to abut each other in the bolting position.
