Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the embodiments of the above-mentioned drawings.

[0016] see Figure 1-3 A pair of fixed hinges I3 and Hinge II4 are respectively arranged at the upper and lower parts of the junction of the window frame 1 and the sash 2 of the rotating shaft type electric window opening device, and a rotating shaft 5 runs through the hinges I and Hinge II. I is supporting and is connected with hinge II, so that the rotation of the rotating shaft can drive the opening and closing of the sash.

[0017] The power mechanism and power transmission mechanism to realize the opening and closing of the window sash are arranged at the lower part of the window frame, and the geared motor 12 and the worm gear reducer 11 are used as the power output. The worm of the worm gear reducer is connected with the output shaft of the geared motor with a coupling 13, This can make the structure compact and reduce the occupi...

Abstract

A rotating axle-type electric window opener features that a pair of hinges is arranged between window frame and window sash, a rotating axle passing through then is driven by an electric motor via worm gear speed reducer, controllable engaged clutch and a pair of internally engaged gears for opening the window sash, an electromagnet controlled lock is installed between window frame and window sash, and a handle for manually opening the window sash is arranged.

Description

technical field [0001] The invention relates to an opening and closing device for a casement window, in particular to a window opening device which realizes opening and closing of a window sash through a pair of inner meshing gears of a power transmission mechanism to drive a rotating shaft and controls a window lock by an electromagnet. Background technique [0002] The window sashes of modern residences and office buildings are mostly aluminum alloy or plastic steel mobile window sashes, but this kind of window sashes can only be half opened. In fact, fully open window sashes are deeply favored by people and have a large market. The casement windows of rotary sash are mostly opened and closed manually. With the development of science and technology, automatic opening and closing devices for casement windows have also emerged at the historic moment, such as the "grain depot automatic opening and closing window" of CN2489056y , the power it adopts is a geared motor and a wor...
