[0019] The utility model discloses a reconstruction structure of existing window, directly set up new window frame 2 in old window frame 1, and adopt screw fixed connection, and set up outdoor side baffle plate 3 and indoor side baffle plate 4 and shield old window frame 1, and outdoor side baffle plate 3 and indoor side baffle plate 4 are fixedly connected to new window frame 2, fill gap 101 and glue injection space 102 with foaming glue, further improve the connection strength of new window frame 2, guarantee the sealing property of new window simultaneously, need not remove old window frame 1 to realize the reconstruction, reduce the danger coefficient, save time and labor simultaneously, thereby reduce the cost of window replacement.

[0020] It should be noted that the window frame needs to be leveled before installation, so that the vertical column is vertical and the horizontal column is horizontal. The new window frame 2 also needs to be leveled before installation, and its height in the old window frame 1 also needs to be adjusted. In the present embodiment, the bottom of the new window frame 2 is provided with at least two first pads 51, the bottom of the first pad 51 is an A inclined surface 511, the old window frame 1 is provided with a second pad 52 corresponding to the first pad 51, the top of the second pad 52 is a B inclined surface 521, the A inclined surface 511 and the B inclined surface 521 are both provided with mutually matching convex edges, the first pad 51 and the second pad 52 are preferably arranged as right-angled triangles, and the A inclined surface 511 and the B inclined surface 521 are inclined surfaces of right-angled triangles. The A inclined surface 511 and the B inclined surface 521 are both provided with a plurality of convex edges, and the convex edges of the A inclined surface 511 and the convex edges of the B inclined surface 521 are mutually engaged. Through this structure, the horizontal adjustment of the new window frame 2 in the old window frame 1 can be realized. The two first pads 51 are respectively arranged on the left and right sides of the bottom of the new window frame 2, the number of the second pads 52 is the same as that of the first pads 51, and the second pads 52 are arranged on the top of the lower profile of the old window frame 1. The second pads 52 can be fixedly connected to the old window frame 1 by screws, or the second pads 52 can be directly placed on the old window frame 1. This action is completed before the new window frame 2 is placed. After completion, the first pads 51 are placed on the second pads 52. By adjusting the first pads 51 on the left and right sides up and down, the height of the new window frame 2 can be raised or lowered, and the levelness of the new window frame 2 can be adjusted.

[0021] In the present embodiment, the left and right sides of the new window frame 2 are threadedly connected with adjusting members 60, the end of the adjusting member 60 abuts and rotates on the old window frame 1, the adjusting member 60 includes an outer shell and a top screw, the outer shell is fixed on the new window frame 2, and the top screw is threadedly connected to the outer shell, and one end of the top screw abuts the old window frame 1. Through this structure, the vertical adjustment of the new window frame 2 can be realized. The adjusting member 60 is preferably provided with four, and two are correspondingly arranged on the left and right sides of the new window frame 2.

[0022] In this embodiment, multiple connecting plates 23 are provided on the outer side of the new window frame 2. The multiple connecting plates 23 are located on the top, bottom, left, and right sides of the new window frame 2. Each connecting plate 23 has a receiving part 230 that protrudes forward from the new window frame 2. The top of the outdoor side retractable plate 3 is provided with an overlapping part 33. The overlapping part 33 is located between the receiving part 230 and the new window frame 2, and the overlapping part 33 is fixedly connected to the receiving part 230 by a diagonal screw. The connecting plate 23 is T-shaped in general. Its flat part is fixedly connected to the new window frame 2 by screws. The receiving part 230 protrudes forward from the new window frame 2 and is used to connect with the outdoor side retractable plate 3. The overlapping part 33 of the outdoor side retractable plate 3 is located between the receiving part 230 and the new window frame 2. The overlapping part 33 and the receiving part 230 are connected in sequence by diagonal screws, so that the new window frame 2 is fixedly connected to the outdoor side retractable plate 3 by the connecting plate 23. The old window frame 1 is installed inside the window opening. Sealant 103 is applied to the junctions of the outdoor side panel 3 / indoor side panel 4 with the window opening, and to the junctions of the overlap 33 with the new window frame 2. The sealant 103 fills the junctions, improving aesthetics and sealing. The side of the indoor side panel 4 furthest from the new window frame 2 is abutted against the old window frame 1 by a sealing strip 41, bringing the indoor side panel 4 close to the indoor surface of the old window frame 1 and reducing the space occupied indoors. During installation, the indoor side panel 4 is first fixedly connected to the outside of the new window frame 2, and the sealing strip 41 on the other side of the indoor side panel 4 abuts against the old window frame 1, ensuring a sealed overlap between the indoor surfaces of the new window frame 2 and the old window frame 1. The outdoor side panel 3 is then installed after this process, facilitating installation.

[0023] In summary, the new window frame 2 is fixedly connected to the indoor side panel 4 and the connecting plate 23. This can be completed before leaving the factory. First, place the second shim 52 on the old window frame 1. Note that if the old window frame 1 has a baffle, it needs to be cut off first. Then, place the first shim 51 on the second shim 52. Place the new window frame 2 inside the old window frame 1 and place it on the first shim 51. Adjust the height of the first shim 51 on the second shim 52 according to the new window frame 2. The worker also needs to level the new window frame 2 on site. The height and horizontal direction of the new window frame 2 can be adjusted by the matching height of the first shim 51 and the second shim 52. Alternatively, the adjustment can be done first. After determining the height of the first pad 51 and the levelness of the two first pads 51, place the new window frame 2 into the old window frame 1. After placement, install the outdoor side trim 3 and use angled screws to fix the connecting plate 23 and the outdoor side trim 3. At this time, the new window frame 2 is temporarily fixed in the old window frame 1. Then, adjust the left and right sides of the new window frame 2 through the adjusting piece 60 so that the new window frame 2 is in the center of the old window frame 1, and ensure that it is horizontal and vertical. Then, fix the new window frame 2 and the old window frame 1 with screws. Finally, fill with expanding foam. Alternatively, expand foam can be filled before installing the outdoor side trim 3.

[0024] The above embodiment is the preferred embodiment of the utility model, and any similar structure and equivalent changes made should belong to the protection scope of the utility model.
