[0016] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0017] Example 1 like Figures 1-6 As shown in this embodiment, an assembled fireproof door and window includes a door frame 1, which is the basic load-bearing component of the entire fireproof door and window. An installation groove 101 is specially provided inside the door frame 1. The size of the installation groove 101 matches that of the inner frame 2 for installing the inner frame 2. On the door frame 1, a recess 103 is provided between two pin grooves 102 on the same side, providing space for the pressure block 402 of the snap-fit ​​assembly 4. Furthermore, concealing frames 5 are installed inside the door frame 1 on both sides of the installation groove 101. The concealing frames 5 can cover the installation area, improving the overall aesthetics.

[0018] The inner frame 2 is a key structure for fixing the transparent window 3, and it is installed in the mounting groove 101 of the door frame 1. Two pins 201 are fixed to each side of the inner frame 2. These pins 201 cooperate with the pin slots 102 on the door frame 1 to connect the inner frame 2 to the door frame 1. The inner frame 2 consists of a U-shaped frame 202 and a crossbar 203. The crossbar 203 is located at the opening of the U-shaped frame 202, and its two ends are connected to the two ends of the opening of the U-shaped frame 202, together securing the transparent window 3 firmly.

[0019] The transparent window 3 is installed inside the inner frame 2 and is made of high-quality fireproof material. This material has good high temperature resistance and fire insulation effect, and can effectively block the spread of fire and smoke in the event of a fire.

[0020] The snap-fit ​​assembly 4 is the core component for quickly connecting and fixing the inner frame 2 and the door frame 1. It is used to snap the pin 201 into the pin groove 102. It includes a slider 401, a pressure block 402, two push rods 403 and a locking bolt 404. The slider 401 is slidably connected in the pin groove 102. The slider 401 has an L-shaped groove 4011, the shape of which is adapted to the pin 201. The pressure block 402 is located in the middle of the recess 103 and is a key component for operating the snap-fit ​​assembly. Two push rods 403 are rotatably connected to both sides of the pressure block 402, and the end of the push rod 403 away from the pressure block 402 is hinged to the corresponding slider 401, realizing the linkage between the pressure block 402 and the slider 401. The locking bolt 404 is installed on the pressure block 402, and its threaded end is movably engaged with the side wall of the recess 103 for further fixation after the pressure block 402 is pressed into the recess 103.

[0021] The concealing frame 5 has mounting holes 501 at each of its four corners. Screws 6 are installed inside the mounting holes 501, with their threaded ends engaging with the side wall of the door frame 1, thus securing the concealing frame 5 to the door frame 1. A cap 7 is also provided at the opening of the mounting hole 501 to cover the screws 6, preventing them from being exposed and affecting the aesthetics. Slots 204 are provided on the side walls of both ends of the opening of the U-shaped frame 202. Each end of the crossbar 203 has an ear plate 205 fixed to it, which is inserted into the slot 204 on the same side. Multiple screws 206 are installed on the ear plates 205, with their threaded ends engaging with the side wall of the slot 204, thus firmly connecting the crossbar 203 to the U-shaped frame 202.

[0022] Connection between inner frame 2 and door frame 1: The pins 201 on both sides of the inner frame 2 are movably engaged in the pin slots 102 on both sides of the mounting slot 101 of the door frame 1 through the snap-fit ​​assembly 4. When the pressure block 402 is outside the recess 103, the opening of the L-shaped groove 4011 on the slider 401 is aligned with the pin groove 102, allowing the pin 201 to be smoothly installed into the L-shaped groove 4011. When the pressure block 402 is pressed into the recess 103, the push rod 403 pushes the slider 401 to slide, causing the opening of the L-shaped groove 4011 to intersect with the pin groove 102. The pin 201 is then confined within the L-shaped groove 4011 and cannot slide out of the pin groove 102, thus locking the pin 201 into the pin groove 102. At this point, the pressure block 402 and the push rod 403 are completely submerged in the recess 103. Finally, the locking bolt 404 is tightened to further secure the pressure block 402, ensuring the stability of the connection.

[0023] The shading frame 5 is fixed to the door frame 1 by screw 6. Screw 6 passes through the mounting holes 501 at the four corners of the shading frame 5, and its threaded end is engaged with the side wall of the door frame 1. After the shading frame 5 is installed, the plug 7 is installed at the opening of the mounting hole 501 to cover the screw 6.

[0024] The ear plates 205 at both ends of the crossbar 203 are inserted into the slots 204 on the side walls of the openings of the U-shaped frame 202, respectively. Then, by tightening the multiple screws 206 on the ear plates 205, the threaded ends of the screws 206 are engaged with the side walls of the slots 204, thereby firmly connecting the crossbar 203 and the U-shaped frame 202 together to form a complete inner frame 2 to fix the transparent window 3.
