Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a fireproof door and window with good sealing performance. Background Technology

[0002] Doors and windows are an important component of building envelope systems. As people's living standards continue to improve, the requirements for doors and windows are becoming more and more diversified. Fireproof doors and windows use thermally broken aluminum profiles and insulated glass, and have functions such as energy saving, sound insulation, noise reduction, dust prevention, and waterproofing. At present, fireproof doors and windows are widely used in major buildings.

[0003] In existing technologies, conventional fireproof doors and windows are usually sealed to the wall with foam adhesive during installation. However, over time, the foam adhesive can deteriorate, resulting in a poor seal. Additionally, the window frame and sash may not fit tightly together, leading to a poor sealing effect. Furthermore, the window frame's sound insulation and noise reduction capabilities are inadequate, failing to effectively isolate noise. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-4 This utility model discloses a fireproof door and window with good sealing performance, including a window frame 1. Window sashes 2 are hinged to the left and right side walls of the front side of the window frame 1. The window sashes 2 are locked and fixed to the window frame 1 by a latch 3. A U-shaped groove 4 is opened at the corresponding position of the front side of the window frame 1 and the periphery of the window sash 2. A sealing cover plate 6 is installed on the front side of the window frame 1 corresponding to the U-shaped groove 4 by a locking mechanism 5. A first sealing mechanism 7 is fixedly installed on the inner wall of the U-shaped groove 4 near the center. A noise reduction mechanism 8 is fixedly installed on the left and right sides of the first sealing mechanism 7. A second sealing mechanism 9 is provided at the corresponding position of the rear side of the window sash 2 and the window frame 1. A third sealing mechanism 10 is installed at the corresponding position of the rear side of the window sash 2 and the sealing cover plate 6. A fourth sealing mechanism 11 is provided on the outer surface of the window frame 1.

[0021] Specifically, the locking mechanism 5 includes a fixing block 501 and a locking bolt 502. The four corners of the rear side of the sealing cover plate 6 are fixedly installed with fixing blocks 501, and the fixing blocks 501 are locked and fixed to the window frame 1 by the locking bolts 502.

[0022] In this embodiment, the locking bolt 502 locks the fixing block 501 to the window frame 1, thereby achieving the effect of locking the sealing cover 6 to the front side of the window frame 1.

[0023] Specifically, the first sealing mechanism 7 includes a rubber block 701, a mounting groove 702, a spring 703, and an arc-shaped groove 704. The upper surface of the rubber block 701 is provided with a mounting groove 702. A spring 703 is fixedly installed in the mounting groove 702, and the spring 703 is fixedly connected to the inner wall of the U-shaped groove 4. The side of the rubber block 701 near the window sash 2 has an arc-shaped structure, and the side of the window sash 2 corresponding to the rubber block 701 is provided with an arc-shaped groove 704.

[0024] In this embodiment, the spring 703 pushes the lower surface of the rubber block 701 into the arc-shaped groove 704 on the window sash 2, so that the rubber block 701 and the window sash 2 form a sealed state.

[0025] Specifically, the noise reduction mechanism 8 includes sound-absorbing cotton 801 and sound insulation board 802. The sound-absorbing cotton 801 and sound insulation board 802 are fixedly installed on the side of the mounting groove 702 and the sealing cover plate 6 facing the rubber block 701 in sequence.

[0026] In this embodiment, the sound-absorbing cotton 801 and the sound insulation board 802 further improve the sound insulation and noise reduction function of the window frame 1.

[0027] Specifically, the second sealing mechanism 9 includes a slot 901, a rubber sealing strip 902, and teeth 903. The slot 901 is provided on the rear side of the window sash 2 facing the window frame 1. The rubber sealing strip 902 is snapped into the slot 901. Teeth 903 are provided on the rubber sealing strip 902 near its edge. The third sealing mechanism 10 has the same structure as the first sealing mechanism 7.

[0028] In this embodiment, the rubber sealing strip 902 is snapped into the slot 901, so that the rubber sealing strip 902 and the toothed structure 903 fit against the front side of the rear window frame 1, and the rear side of the window sash 2 fits tightly against the front side of the window frame 1. Similarly, the third sealing mechanism 10 makes the rear side of the window sash 2 fit tightly against the front side of the sealing cover 6, so as to improve the sealing effect.

[0029] Specifically, the fourth sealing mechanism 11 includes a mounting frame 111 and a high-temperature expansion strip 112. The mounting frame 111 is provided on the side of the window frame 1, and the high-temperature expansion strip 112 is fixedly installed in the mounting frame 111.

[0030] In this embodiment, the mounting frame 111 is used to install the high-temperature expansion strip 112. The high-temperature expansion strip 112 expands when heated, causing it to press tightly against the wall, thus forming a better sealing effect.

[0031] In use, the high-temperature expansion strip 112 is installed via the mounting frame 111 of the fourth sealing mechanism 11. The high-temperature expansion strip 112 expands when heated, causing it to press tightly against the wall, creating a good seal. The spring 703 in the first sealing mechanism 7 pushes the lower surface of the rubber block 701 into the arc-shaped groove 704 on the window sash 2, creating a seal between the rubber block 701 and the window sash 2. The second sealing mechanism 9 connects the rubber sealing strip 902 with the toothed structure 903 to the front side of the rear window frame 1. The surface is fitted so that the rear side of the window sash 2 is tightly fitted to the front side of the window frame 1. Similarly, the third sealing mechanism 10 makes the rear side of the window sash 2 tightly fitted to the front side of the sealing cover 6, so as to improve the sealing effect and effectively prevent air leakage when the window sash 2 is closed. In the event of a fire, it can better prevent external smoke and dust from entering. The sound-absorbing cotton 801 and the sound insulation board 802 in the noise reduction mechanism 8 further improve the sound insulation and noise reduction function of the window frame 1, making the window frame 1 less likely to transmit sound, reducing external noise pollution, and facilitating use.

[0032] In summary, this fireproof door and window with good sealing performance provides better sealing between the window frame 1 and the wall and the window sash 2, effectively preventing air leakage when the window sash 2 is closed, better preventing external smoke and dust from entering, and increasing the sound insulation and noise reduction function of the window frame 1, which can reduce external noise and facilitate use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
