The grooves of the bottom frame, side frame and top frame are filled with sealing strips. Then the glass is placed in the grooves of the bottom frame and top frame. The L-shaped push plate drives the triangular block to separate from the limiting block, which facilitates the separation of the side frame from the bottom frame and the top frame. This allows the bottom frame, side frame and top frame to be disassembled and assembled, which is convenient for glass replacement.
[0004] However, using the above method, it is difficult to position the corners of the window frame during the manufacturing process, making it difficult to keep it flat and affecting the quality of the window frame. Utility Model Content
[0005] The purpose of this utility model is to provide a modular window frame that allows for easy positioning of the corners of the window frame during its manufacturing process, ensuring flatness and thus improving the quality of the window frame.
[0006] To achieve the above objectives, this utility model provides a combined window frame, including a bottom frame, side frames, and a top frame. Both ends of the bottom frame, side frames, and top frame are 45° cutouts. Both ends of the bottom frame and top frame are fitted and contacted with the ends of the side frames to form a plastic sealed window frame. The model also includes a positioning device.
[0007] The positioning device includes a first corner piece, a second corner piece, a force application component, and a protective component. The first corner piece is fixedly connected to the bottom frame and detachably connected to the side frame.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0021] The first embodiment of this application is as follows:
[0022] Please see Figures 1 to 5 ,in Figure 1 This is a schematic diagram of the overall structure of the modular window frame. Figure 2 This is a structural diagram of the base frame. Figure 3 This is a structural diagram of the top frame. Figure 4 This is a structural diagram of the side frame. Figure 5 This is a front sectional view of the side frame. This utility model provides a combined window frame: including a bottom frame 101, a side frame 102, a top frame 103, and a positioning device. The positioning device includes corner bracket 104, corner bracket 2 105, a force-applying component, and a protective component. Both corner bracket 104 and corner bracket 2 105 have raised particles 106. The force-applying component includes a bottom anti-slip pad 107, a top anti-slip pad 108, and a side anti-slip pad 109. The protective component includes a buffer pad 110 and a sound-absorbing pad 111. The aforementioned solution solves the problem of difficulty in positioning the corners of the window frame during manufacturing, making it difficult to keep flat and affecting the quality of the window frame. It is understood that the aforementioned solution can facilitate the positioning of the corners of the window frame during manufacturing, keeping them flat, thereby improving the quality of the window frame. It can also provide buffer protection for the side frame 102, reduce noise generation, and is more environmentally friendly.
[0023] In this specific embodiment, the bottom frame 101, side frames 102, and top frame 103 all have 45° cuts at both ends. The ends of the bottom frame 101 and top frame 103 are fitted and contacted with the ends of the side frames 102 to form a plastic sealed window frame. There are two side frames 102, which are fitted and contacted on both sides of the upper surface of the bottom frame 101. The top ends of the two side frames 102 are fitted and contacted with the ends of the top frame 103. After the top frame 103, the bottom frame 101, and the two side frames 102 are spliced together, a window frame is formed. The glass is placed into the grooves of the bottom frame 101 and the top frame 103 to complete the installation of the window frame.
[0024] The first corner piece 104 is fixedly connected to the bottom frame 101 and detachably connected to the side frame 102. The second corner piece 105 is fixedly connected to the top frame 103 and detachably connected to the side frame 102. The force-applying components are provided on both the bottom frame 101 and the top frame 103. The protective components are provided on the side frame 102. The first corner piece 104 is symmetrically fixed to both sides of the upper surface of the bottom frame 101, and the second corner piece 105 is symmetrically fixed to both sides of the lower surface of the top frame 103. By setting the first corner piece 104 and the second corner piece 105, when the side frame 102 is installed, the side frame 102 will be snapped into the corresponding corner piece 104 or corner piece 105 of the bottom frame 101. The corner pieces 105 of the top frame 103 ensure that the joints between the side frame 102 and the bottom frame 101, as well as between the side frame 102 and the top frame 103, are smooth and flat. The corner pieces 104 and 105 can respectively lift the connection gaps between the bottom frame 101 and the top frame 103 from the inside, effectively connecting the gaps more firmly and preventing the window frame from loosening after long-term use. The force-applying components are provided on the front sides of the bottom frame 101 and the top frame 103, making it easy to push the window frame after installation. The protective components are provided on the sides of the two side frames 102 that are far apart from each other, which can protect the window frame.
[0025] Secondly, the protruding particles 106 are located on the outer surfaces of the first corner piece 104 and the second corner piece 105, respectively. The protruding particles 106 provide a point of force for the operator, so that when installing the side frame 102, the first corner piece 104 or the second corner piece 105 can be stably gripped through the protruding particles 106, thereby facilitating the installation of the side frame 102.
[0026] Meanwhile, the bottom anti-slip pad 107 is fixedly connected to the bottom frame 101 and located on one side of the bottom frame 101; the top anti-slip pad 108 is fixedly connected to the top frame 103 and located on one side of the top frame 103; the side anti-slip pad 109 is fixedly connected to the side frame 102 and located on one side of the side frame 102. The bottom anti-slip pad 107 is embedded in the front side of the bottom frame 101, the top anti-slip pad 108 is embedded in the front side of the top frame 103, and the side anti-slip pad 109 is embedded in the front side of the side frame 102. The top anti-slip pad 108, the side anti-slip pad 109, and the top anti-slip pad 108 are all made of soft rubber material, which increases the friction between the operator's hand and the window frame when the window frame is pushed after installation, making it easier to push the window frame.
[0027] In addition, the buffer pad 110 is fixedly connected to the side frame 102 and located on one side of the side frame 102; the sound-absorbing pad 111 is fixedly connected to the side frame 102 and located on the side of the side frame 102 near the buffer pad 110. The sound-absorbing pad 111 and the buffer pad 110 are arranged sequentially on the two sides of the side frames 102 that are far apart from each other. The sound-absorbing pad 111 is made of polyester fiber sound-absorbing cotton, and the buffer pad 110 is made of polymer sponge. By setting the buffer pad 110 and the sound-absorbing pad 111, when using this window frame, when the window frame is opened and closed, the side frame 102 can be buffered and protected when it comes into contact with and collides with the wall, and the noise generation can be reduced, which is more environmentally friendly.
[0028] When using a combined window frame according to this embodiment, by setting the first corner piece 104 and the second corner piece 105, when the side frame 102 is installed, the side frame 102 will be snapped into the first corner piece 104 of the corresponding bottom frame 101 or the second corner piece 105 of the top frame 103. This makes the joint between the side frame 102 and the bottom frame 101, and between the side frame 102 and the top frame 103, flat and smooth. The first corner piece 104 and the second corner piece 105 can respectively lift the connection gap between the bottom frame 101 and the top frame 103 from the inside, which can effectively connect the gap more firmly and effectively prevent the window frame connection from loosening after long-term use.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
