Technical Field

[0001] The utility model relates to the technical field of casement windows, in particular to a sun-proof inward-opening casement window. Background Technique

[0002] In modern architecture, more and more glass is used from the wall surface to the roof. The transparency of the glass enables people to fully feel nature, natural landscapes, natural light and natural space. However, it also brings the hidden danger of increased energy consumption in heating and cooling. Building shading can prevent harmful direct sunlight and reduce the solar radiation heat transmitted into the room, which is one of the effective measures to eliminate and prevent indoor overheating in summer.

[0003] For example, the Chinese utility model patent with the publication number of CN213391704U. This utility model relates to an internally-mounted electric casement window. An electric casement window motor for driving the window sash to rotate is installed in the profile cavity of the window frame. The output square shaft of the electric casement window motor exposes the window frame and is connected to one end of a support rod, and the other end of the support rod is connected to the window sash; an electric lock box for locking and unlocking the window sash is installed on the window sash; the electric lock box is connected to the controller through a first power supply wiring, the electric casement window motor is connected to the controller through a second power supply wiring, and the rain drop sensor is connected to the controller through a third power supply wiring. The corresponding actions of the electric casement window motor and the electric lock box can be controlled through the function keys on the control panel, so as to realize the automatic opening and closing of the window sash.

[0004] However, there are still some problems. Although the corresponding actions of the electric casement window motor and the electric lock box can be controlled through the function keys on the control panel, and then the automatic opening and closing of the window sash can be realized, the heat insulation effect of the casement window still needs to be improved. In summer, it cannot effectively isolate the external sunlight, resulting in the continuous rise of the indoor temperature under the sunlight irradiation, reducing the comfort of users using the aluminum alloy casement window. Therefore, a sun-proof inward-opening casement window is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a sun-proof inward-opening casement window, which has the advantage of sun protection and solves the problem that the external sunlight cannot be effectively isolated in summer.

[0006] To achieve the above object, the utility model provides the following technical scheme: A sun-proof inward-opening casement window, including a fixed frame, a connection frame is hinged to the front of the fixed frame, a glass window is inlaid in the connection frame, a protection box is fixed on the top of the fixed frame, a rotating rod is rotatably connected inside the protection box, two baffles are fixed on the outer surface of the rotating rod, and a meshing wheel is fixed on the outer surface of the rotating rod;

[0007] The outer surface of the meshing wheel is drivingly connected to a meshing chain that penetrates to the outside of the protective box.

When the magnetic strip moves to the bottom, it will be magnetically connected to the magnetic plate at the bottom, so that the overall sunshade component will not flutter due to excessive wind. The provided fixing member enables the magnetic strip to be disassembled, making it convenient to replace the sunshade curtain later, effectively improving the overall practicality.

[0026] 2. For this sunshade inward-opening casement window, by pulling the meshing chain, the meshing wheel can be rotated, thereby rotating the rotating rod, without the need for electric drive, reducing the power demand.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 2 , in this embodiment, a sun protection inward-opening casement window includes a fixed frame 1. A connecting frame 2 is hinged to the front surface of the fixed frame 1. A handle 13 is fixed to the front surface of the connecting frame 2. A sponge pad is sleeved on the outer surface of the handle 13. By providing the handle 13, it is convenient to pull the connecting frame 2 to move. A sealing gasket 14 is fixed to the back surface of the connecting frame 2. The sealing gasket 14 is an annular gasket. By providing the sealing gasket 14, the sealing performance at the connection between the connecting frame 2 and the fixed frame 1 can be effectively improved, thereby effectively preventing rainwater from entering the house interior.

[0033] In addition, a glass window 3 is inlaid in the connecting frame 2. A sun protection film is fixed to the front surface of the glass window 3. The sun protection film is a glass heat insulation film, which can further improve the overall sun protection performance. A protection box 4 is fixed to the top of the fixed frame 1. A rotating rod 5 is rotatably connected inside the protection box 4. A fixed bearing 11 is fixed to the left inner wall of the cavity of the protection box 4. The inside of the fixed bearing 11 is fixed to the rotating rod 5. By providing the fixed bearing 11, the rotation of the rotating rod 5 can be more stable. Two baffles 6 are fixed to the outer surface of the rotating rod 5. A meshing wheel 7 is fixed to the outer surface of the rotating rod 5.

[0034] Furthermore, the outer surface of the meshing wheel 7 is drivingly connected to a meshing chain 8 that penetrates to the outside of the protective box 4. A meshing block is fixed on the outer surface of the meshing wheel 7, and a meshing hole adapted to the meshing block is formed inside the meshing chain 8. By providing the meshing block and the meshing hole, when the meshing chain 8 is pulled, the meshing wheel 7 will rotate, thereby causing the rotating rod 5 to rotate. A sunscreen component 9 that penetrates to the outside of the protective box 4 is fixed on the outer surface of the rotating rod 5. The sunscreen component 9 is used to improve the overall sunscreen property. A friction block 10 is fixed on the right side wall of the inner cavity of the protective box 4. A friction pad is fixed inside the friction block 10, and the friction pad is in close contact with the rotating rod 5. By providing the friction block 10, the friction force when the rotating rod 5 rotates can be effectively increased, thereby effectively preventing the rotating rod 5 from rotating due to gravity or wind force. A magnetic plate 12 is fixed inside the fixed frame 1.

[0035] Generally speaking, by providing the friction block 10, the friction force received when the rotating rod 5 rotates can be effectively increased, and further the stability of the rotation of the rotating rod 5 can be effectively ensured. And by providing the sealing gasket 14, the sealing property at the connection between the fixed frame 1 and the connection frame 2 can be effectively improved, making the overall more practical.

[0036] Please refer to Figure 3 , in this embodiment, the sunscreen component 9 includes a sunscreen curtain 901, a limit block 902, a fixing member 903 and a magnetic strip 904. The sunscreen curtain 901 is fixed to the rotating rod 5, and the sunscreen curtain 901 is wound around the outer surface of the rotating rod 5. The provided sunscreen curtain 901 can prevent sunlight from entering the room, thereby effectively improving the overall sunscreen property.

[0037] Additionally, the sunscreen curtain 901 penetrates to the outside of the protective box 4. The bottom of the sunscreen curtain 901 is fixed to the limit block 902, and the outer surface of the limit block 902 is fixed to the fixing member 903. The fixing member 903 includes a fixing bolt 9032 and two clamping blocks 9031. The two clamping blocks 9031 are threadedly connected to the fixing bolt 9032. The limit block 902 is located between the two clamping blocks 9031. The provided fixing bolt 9032 can connect and fix the two clamping blocks 9031, thereby fixing the limit block 902 between the two clamping blocks 9031, enabling the magnetic strip 904 to be fixed to the sunscreen curtain 901. The magnetic strip 904 is fixed inside the fixing member 903.

[0038] Generally speaking, the provided magnetic strip 904 can be magnetically connected to the magnetic plate 12, so that the sunscreen curtain 901 will not flutter. And the two clamping blocks 9031 are fixed by the fixing bolt 9032, making it convenient to disassemble the clamping blocks 9031 subsequently, and further making the overall more practical.

[0039] The working principle of the above embodiment is as follows:

[0040] By pulling the meshing chain 8, the meshing wheel 7 can be rotated, so that the rotating rod 5 rotates together. Since the friction block 10 is in close contact with the rotating rod 5, a relatively large force is required to pull the meshing chain 8, making the rotation of the rotating rod 5 more stable. When the rotating rod 5 rotates, the sunscreen curtain 901 wound around the rotating rod 5 enters a slack state. Then, under the gravity of the magnetic strip 904 and the fixing member 903, it moves downward to the bottom. After the magnetic strip 904 moves downward, it contacts the magnetic plate 12 on the fixed frame 1, and then the magnetic strip 904 and the magnetic plate 12 are magnetically connected, effectively preventing the sunscreen curtain 901 from being blown up by the external wind and making the sunscreen of the sunscreen curtain 901 more stable. When the sunscreen curtain 901 needs to be retracted later, pulling the other side of the meshing chain 8 can make the meshing wheel 7 rotate in the reverse direction, so as to wind the sunscreen curtain 901 around the outer surface of the rotating rod 5 again. The magnetic strip 904 and the fixing member 903 have a certain gravity, and under the limit of the baffle 6, the sunscreen curtain 901 can be wound around the outer surface of the rotating rod 5 smoothly. When the sunscreen curtain 901 needs to be replaced later, only by rotating the fixing bolt 9032, the disassembly of the fixing member 903 and the sunscreen curtain 901 can be completed, so that the fixing member 903 can be reused. The overall structure is simple, effectively improving the overall sun protection performance, making the whole more practical.
