发明名称 Road/sidewalk shaft cover has at least two rotating bolts at the flat bar which can be operated externally in an assembly which prevents the entry of dirt and sand and is robust in heavy traffic with smooth bolt opening
摘要 The road/sidewalk shaft has a cover with at least two rotating bolts at the flat bar (7) in a release mounting. A housing section is mounted at each bolt, with an arc-shaped peripheral wall and upper and lower closure walls. The housing section swings at a fixed housing section, which also has an arc-shaped peripheral wall and upper and lower closure walls. Each bolt is keyed to a rotating bolt axis (11), with an operating knob (12), which can be accessed from the upper side of the shaft cover (1). Each bolt axis (11) is within a hub (10), as part of the plastics housing (8) which shrouds the rotary bolt within the shaft cover (1).
