AI Technical Summary
Due to the existence of window beams in the existing double-fan casement windows, the view is blocked when the window is closed, and the sealing is insufficient, which affects the insulation effect.
A double-fan case plastic steel window is designed, and the window beam is rotatably connected to one of the casement windows. The sealing member drives the window beam to abut on the inner side wall of the window frame to achieve sealing and support of the window beam. When the casement window is opened, the window beam moves accordingly, reducing the obstruction of the field of view.
It improves the view width of casement windows, enhances the sealing and insulation effect of windows, and reduces the view obstruction when windows are closed.

Abstract
Description
Technical Field
[0001] This application relates to the field of plastic-steel windows, and in particular to a double-sash casement plastic-steel window. Background Art
[0002] Plastic-steel doors and windows are mainly made of polyvinyl chloride (UPVC) resin, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. They are extruded into profiles and then made into door and window frames and sashes by cutting, welding or screwing.
[0003] A casement window is a window in which the sash is connected to the side of the window frame by hinges and the sash rotates horizontally by pushing and pulling; a double-sash casement window is a casement window with two sashes opening in opposite directions. There is a window beam between the currently used double-sash casement windows. The window beam is used to improve the stability when the casement window is closed, but the presence of the window beam blocks the view of the double-sash casement window and the view is not wide. Utility Model Content
[0004] In order to reduce the view blockage of the double-sash casement window after the window is opened, this application provides a double-sash casement plastic-steel window.
[0005] A double-sash casement plastic-steel window provided by this application adopts the following technical solution:
[0006] A double-sash casement plastic-steel window includes a window frame, two casement windows, a window beam and a seal. Both of the two casement windows are rotatably connected to the window frame. The window beam is vertically arranged, and the vertical projection of the window beam is strip-shaped. The window beam is vertically rotatably connected to one of the casement windows. When the two casement windows are closed, the seal abuts the window beam against the inner side wall of the window frame and the window beam abuts against the two casement windows.
[0007] By adopting the above technical solution, when the window is in the closed state, the window beam abuts against the two casement windows under the action of the seal. The window beam plays a supporting role for the casement windows and seals the gap between the two casement windows. When both casement windows need to be opened, the staff can rotate the casement windows, which will drive the window beam to move with the casement windows at this time. The window beam disengages from the window frame, and there is no blockage in the middle of the window frame, improving the view openness of the casement window.
[0008] Optionally, the seal includes a sliding column. The sliding column is arranged on the end face of the window beam. A sliding groove for the sliding column to slide is opened on the window frame. The sliding groove is L-shaped. When the sliding column slides in the sliding groove, the window beam rotates.
[0009] By adopting the above technical solution, when the casement window with a window beam needs to be closed, the user aligns the sliding column on the window beam with the sliding groove on the window frame. The L-shaped sliding groove can drive the window beam to rotate. When the casement window is completely closed, the window beam is located between the window frames and abuts against the two casement windows. The window beam seals the gap between the two casement windows, improving the indoor heat preservation performance.
[0010] Optionally, a guiding inclined surface facilitating the entry of the sliding column is provided on the side of the sliding groove facing the outdoor.
[0011] By adopting the above technical solution, during the installation process of the casement window and the window frame, errors are likely to occur, which may easily cause the position of the window beam relative to the sliding groove to change. The guiding inclined surface facilitates the window beam to enter the sliding groove.
[0012] Optionally, magnets are provided on the casement window, and the magnets are used to keep the cross-section of the window beam perpendicular to the casement window in the vertical direction.
[0013] By adopting the above technical solution, the magnets facilitate the window beam to always adhere to the side wall of the casement window, reducing the influence of the outside world to drive the window beam to rotate relative to the casement window, and facilitating the smooth entry of the sliding column into the sliding groove during the window closing process for the user.
[0014] Optionally, a fixing component for fixing with the window frame is provided on the casement window. The fixing component includes a gear, a rack, and a turntable. The gear is rotatably connected to the casement window, the rack is slidably connected to the casement window in the vertical direction, the rack meshes with the gear, a clamping groove is provided on the inner side wall of the window frame, and the clamping groove is used to clamp the rack. The turntable is used to drive the gear to rotate.
[0015] By adopting the above technical solution, the fixing piece is used to fix the casement window and the window frame when the casement window is closed. After the casement window completes the window closing operation, the user can rotate the turntable. The turntable drives the gear to rotate, the gear drives the rack to move, and the rack cooperates with the clamping groove on the window frame to complete the clamping of the casement window and the window frame.
[0016] Optionally, the fixing component includes a disengaging piece. The disengaging piece includes a spring and a mating rod. A spline groove is provided at one end of the gear, the mating rod is provided on the turntable, a spline is provided at one end of the mating rod, and the spring is used to move the spline away from the spline groove.
[0017] By adopting the above technical solution, when the casement window needs to be opened, the user can first press the turntable so that the spline on the matching rod cooperates with the spline groove on the gear, and then rotate the turntable. The turntable drives the gear to rotate, and the gear drives the rack to move. The rack disengages from the clamping groove, and then the casement window can be pushed open. The disengaging member reduces the user error of the turntable and changes the state of the casement window, improving the rationality of the casement window.
[0018] Optionally, a receiving groove is formed in the casement window, and both the gear and the rack are located in the receiving groove.
[0019] By adopting the above technical solution, the exposure of the gear and rack is reduced, improving the aesthetics of the casement window.
[0020] Optionally, the casement window is connected to the window frame through a four-bar wind brace hinge.
[0021] By adopting the above technical solution, the wind brace hinge is suitable for the casement window, realizing the stability of the casement window and extending the service life of the casement window.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The window beam is rotatably connected to one of the casement windows, and the window beam can move as the casement window is opened, reducing the obstruction of the view after the casement window is opened;
[0024] 2. The sealing member is used to drive the window beam to rotate. When the two casement windows are closed, the window beam is used to seal the gap between the two casement windows, improving the sealing performance of the window and the heat preservation effect indoors.
[0025] 3. The fixing component is used to fix the casement window to the window frame. BRIEF DESCRIPTION OF THE DRAWINGS
