Adopt above-mentioned technical scheme, make the casement under the closure state through setting up limit baffle, limit baffle and output push rod front end butt avoid the casement closure state under the swing, under the biggest open mode of casement, limit baffle and output push rod rear end butt avoid the excessive displacement of output push rod, lead to the casement to be in the most greatly reduced angle that contracts after the open mode, promote product stability.
Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the driving assembly comprises a turbine shaft arranged on the fixing base plate, a worm meshed with the turbine shaft and a hand crank driving the worm to rotate, and the window pushing swing rod is fixedly connected with the turbine shaft through a connecting piece and driven to swing by taking the turbine shaft as a fulcrum through the hand crank.
By adopting the technical scheme, the hand crank drives the sliding window swing rod to swing through the turbine worm, so that the window swing rod has a larger transmission ratio, is compact in structure, stable in transmission and free of noise, and meanwhile, the kinetic energy of the obliquely arranged worm can be transmitted to the horizontal turbine shaft through the vortex worm, so that the hand crank can conveniently apply force.
Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the fixed base plate is provided with a gear shaft installation cavity for installing a turbine shaft and a worm installation cavity for installing a worm, bearings are arranged at two ends of the turbine shaft corresponding to the gear shaft installation cavity, and a movable notch for swinging the push window swing rod is arranged at the position of the fixed base plate corresponding to the gear shaft installation cavity.
By adopting the technical scheme, the gear shaft mounting cavity and the worm mounting cavity are arranged, so that the internal parts of the window opener cannot deviate in the using process, the friction coefficient and the noise of a transmission load are reduced by arranging the bearing, and the swing angle of the window pushing swing rod is limited by arranging the movable notch.
Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the crank is including connecting seat, rocking arm and rocking handle, the connecting seat passes through fastener and worm fixed connection, the rocking arm passes through the articulated elements and is articulated mutually with the connecting seat, makes the rocking arm can pass through the articulated elements and changes application of force direction, the rocking handle is articulated mutually with the rocking arm.
By adopting the technical scheme, the rocking handle is hinged with the rocking arm, and the rocking arm is hinged with the connecting seat, so that when a user drives the window opener to work by hand, the user can adjust the rocking handle according to different window sash scenes by changing the force application direction of the rocking arm, and the operation is more convenient.
The utility model is further described below with reference to the accompanying drawings.
