The window opener comprises a lower bottom plate, a guide rail, a locking hook and an upper bottom plate, wherein one end of the guide rail is installed on the lower bottom plate, the locking hook is hinged to the guide rail, and the upper bottom plate is arranged on the guide rail in a sliding mode. A locking head is fixedly connected to the upper bottom plate. A window opening device and an assistance system are hinged to the upper bottom plate. The other end of the window opening device and the other end of the assistance system are installed at the other end of the guide rail. Both the window opening device and the assistance system are parallel to the guide rail. A telescopic element is installed on the lower bottom plate. The output end of the telescopic element is hinged to one end of the locking hook. The telescopic element can push the locking hook to rotate so that the other end of the locking hook can hook or release the locking head. The window opener has the advantages that manual starting is convenient, the starting speed is stable, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a manually openable window opener and a smoke exhaust system. Background technique [0002] With the improvement of domestic fire safety awareness and standard requirements, there are more and more window openers for building smoke exhaust windows, but the original window openers for building smoke exhaust windows are limited by the stroke of the electric push rod due to their low opening speed and time-consuming opening angle. Insufficient size or complex structure, insufficient self-locking force in the closed state, poor wind resistance and negative pressure, and easy water leakage limit the popularization and promotion of smoke exhaust windows. [0003] Chinese patent CN203559687U discloses a manual window opener, including a handle, the handle is connected to a connecting rope, the connecting rope is connected to one end of a locking mechanism, the locking m...
