[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides an embodiment of an inward-opening casement window with integrated screen, comprising an outer frame 1, a main window frame 2 disposed inside the front end of the outer frame 1, and two sets of openings 18 disposed vertically inside the main window frame 2, with secondary window frames 4 disposed inside the front end of the openings 18, a second handle 5 movably mounted on the left side of the front end of the main window frame 2, a first handle 3 movably mounted on the left side of the front end of the two sets of secondary window frames 4, tempered glass 7 respectively installed and fixed inside the two sets of secondary window frames 4, a first lock groove 15 disposed on the left side inside the openings 18, and a first mounting groove 17 disposed inside the left side of the secondary window frames 4, with a lock block disposed inside the first mounting groove 17. 16. A lock groove 23 is provided on the left side inside the outer frame 1. An installation groove 23 is provided on the left side inside the main window frame 2. A lock block 24 is provided inside the installation groove 23. A fixing foot 10 is fixed at the top and bottom of the right side of the main window frame 2. A fixing bracket 19 is fixed at the top and bottom of the right side of the front end of the outer frame 1. The fixing foot 10 is hinged to the inside of the fixing bracket 19. A fixing foot 22 is fixed at the top and bottom of the right side of the two sets of secondary window frames 4. Four sets of fixing brackets 21 are fixed on the upper and lower right side of the front end of the main window frame 2. The fixing foot 22 is hinged to the inside of the fixing bracket 21.

[0023] The secondary window frame 4 and the opening 18 are symmetrically arranged about the vertical center line of the main window frame 2. The rear end of the second handle 5 passes through the interior of the front end of the main window frame 2 and is fixedly connected to the front end of the second lock block 14. The rear end of the first handle 3 passes through the interior of the front end of the secondary window frame 4 and is fixedly connected to the front end of the first lock block 16.

[0024] Specifically, such as Figures 1-3 As shown, by setting separate secondary window frames 4 at the top and bottom of the front end of the main window frame 2, turning the left handle 3 at the front end of the secondary window frame 4 upwards causes the locking block 16 to exit from the inside of the locking groove 15. After unlocking the secondary window frame 4 inside the opening 18, the secondary window frame 4 can be flipped open to the right. This small window opening method allows for ventilation while reducing the amount of dust entering. At the same time, by turning the left handle 5 at the front end of the main window frame 2 upwards to unlock the main window frame 2 inside the outer frame 1, the main window frame 2 can be opened to the right in a large area. This provides different window opening methods.

[0025] A bottom shell 10 is horizontally fixed at the bottom of the front end of the main window frame 2, and a rotating cylinder 11 is horizontally movably installed inside the bottom shell 10. The two sides of the rotating cylinder 11 pass through the interior of the bottom shell 10. A horizontal bar 8 is horizontally set at the top of the bottom shell 10. A sunshade 9 is set on the rotating cylinder 11. A handle 12 is fixed on the right side of the rotating cylinder 11. A top groove 24 is opened inside the top of the bottom shell 10. The top of the horizontal bar 8 passes through the interior of the top groove 24 and is fixedly connected to the bottom end of the horizontal bar 8. Two sets of hooks 1 27 are fixed on the left and right sides at the middle position of the front end of the main window frame 2. Two sets of hooks 2 6 are fixed on the left and right sides at the top of the front end of the main window frame 2.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, after the sunshade curtain 9 is released from the outside of the rotating cylinder 11 by pulling the horizontal bar 8 upward, the sunshade curtain 9 can be positioned by hooking the horizontal bar 8 onto the two sets of hooks 27 and the two sets of hooks 6. The sunshade curtain 9 can be used to provide auxiliary sunshade and light blocking for the window. By turning the handle 12, the rotating cylinder 11 can be reversed to roll the sunshade curtain 9 back to the outside of the rotating cylinder 11.

[0027] Protective coatings 26 are provided at both ends of the two sets of tempered glass 7;

[0028] Specifically, such as Figure 1 and Figure 4 As shown, by providing a protective coating 26 on the tempered glass 7, which is made of nanomaterials, the protective coating 26 can enhance the scratch resistance of the tempered glass 7, prevent the surface of the tempered glass 7 from being scratched, and at the same time make the tempered glass 7 have anti-fouling properties, effectively preventing fingerprints, oil stains and other stains from adhering to the surface of the tempered glass 7.

[0029] A screen window 25 is installed and fixed inside the rear end of the outer frame 1.

[0030] Working Principle: When installing and using the inward-opening casement window with integrated screen, separate secondary window frames 4 are installed at the top and bottom of the front end of the main window frame 2. Rotating the left-handle 3 at the front end of the secondary window frame 4 upwards causes the locking block 16 to disengage from the lock groove 15, unlocking the secondary window frame 4 inside the opening 18. This allows the secondary window frame 4 to be flipped open to the right, providing ventilation while reducing dust entry. Simultaneously, rotating the left-handle 5 at the front end of the main window frame 2 upwards unlocks the main window frame 2 inside the outer frame 1, allowing the main window frame 2 to open fully to the right. Pulling the horizontal bar 8 upwards releases the sunshade 9 from the outside of the rotating cylinder 11. The sunshade 9 can then be positioned by hooking the horizontal bar 8 onto two sets of hooks 27 and 6, providing auxiliary sun shading and light blocking for the window. In addition, when tempered glass 7 is installed inside the casement window with an integrated inward-opening screen, a protective coating 26 made of nanomaterials is provided on the tempered glass 7 to enhance its scratch resistance and prevent the surface of the tempered glass 7 from being scratched. At the same time, it also makes the tempered glass 7 resistant to dirt, effectively preventing fingerprints, oil stains and other dirt from adhering to the surface of the tempered glass 7.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
