Technical Field
[0001] This utility model relates to the field of fireproof window technology, specifically to an automatic sliding and closing fireproof window. Background Technology
[0002] Fire-resistant windows are windows that, together with their frames, can meet the requirements for fire resistance stability and fire integrity for a certain period of time. They are generally made of wood or steel for the window frame and sash skeleton, filled with non-combustible materials, and equipped with fire-resistant glass, fire-resistant latches, fire-resistant hinges, etc., which can meet certain fire resistance integrity and heat insulation requirements.
[0003] Current fireproof windows cannot automatically close in time to isolate the fire and smoke when a fire occurs. Therefore, we propose a fireproof window that can automatically slide and close. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic sliding and closing fireproof window, which has the advantage of being able to automatically close the fireproof window in time when fire and smoke occur, so as to block the fire and smoke and provide time for safe evacuation. It solves the problem that current fireproof windows cannot automatically close in time to isolate the fire and smoke when fire and smoke occur.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically sliding and closing fireproof window, comprising a window frame and a fireproof window body. The fireproof window body is rotatably installed inside the window frame via hinges. Two second electric push rods are symmetrically rotatably installed inside the window frame near the rear surface of the fireproof window body on both sides, with the ends of the two second electric push rods rotatably connected to the rear surface of the fireproof window body on both sides. A first electric push rod is rotatably installed inside the window frame above the two second electric push rods, with the ends of the two first electric push rods rotatably connected to the outer surfaces of the two second electric push rods. A mounting groove is provided on the front surface of the window frame near the lower surface, and a smoke sensor is fixedly installed inside the mounting groove.
[0006] Preferably, both the first and second electric push rods are electrically connected to the smoke sensor, and the smoke sensor can trigger the first and second electric push rods to work when it detects smoke from a fire.
[0007] Preferably, a manual switch is fixedly installed on the rear surface of the window frame, and both the first electric push rod and the second electric push rod are electrically connected to the manual switch, so that the first electric push rod and the second electric push rod can be controlled by the manual switch.
[0008] Preferably, a baffle is fixedly installed on the inner wall of the window frame near the rear surface of the fireproof window body. After the fireproof window body rotates and closes into the window frame, the rear surface of the fireproof window body contacts the baffle, restricting the rotation of the fireproof window body.
[0009] Preferably, the front surface of the baffle is provided with a groove, and a sealing strip is provided inside the groove. After the fireproof window body is rotated and closed, the rear surface of the fireproof window body and the sealing strip inside the groove on the front surface of the baffle contact each other. The sealing strip plays a sealing role to prevent smoke or rainwater from entering the interior of the building through gaps.
[0010] Preferably, the inner wall of the groove is provided with a slot, and the outer surface of the sealing strip is provided with a protrusion, which is located inside the slot. The sealing strip is fixed inside the groove by the slot and the protrusion, which facilitates the disassembly and replacement of the sealing strip.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

This utility model, by incorporating a window frame, fireproof window body, hinges, a smoke sensor, a first electric push rod, and a second electric push rod, achieves the effect of automatically closing the fireproof window in a timely manner when fire and smoke occur, thereby blocking the fire and smoke and providing time for safe evacuation. The window frame is fixed to the wall of the building. When fire and smoke are detected by the smoke sensor, the first and second electric push rods are triggered to rotate. The first electric push rod drives the second electric push rod to rotate, and the second electric push rod drives the fireproof window body to rotate to complete the closing action, thereby blocking the fire and smoke.
[0013] 2. This utility model achieves a sealing effect between the window frame and the fireproof window body by setting a baffle, a groove and a sealing strip, so as to prevent smoke or rainwater from entering the building through the gap. After the fireproof window body is rotated and closed, the sealing strip inside the groove on the rear surface of the fireproof window body and the baffle front surface comes into contact, and the sealing strip plays a sealing role.
[0014] 3. This utility model achieves the effect of facilitating the disassembly and replacement of the sealing strip by setting the slot and the protrusion. The sealing strip is fixed inside the groove by the slot and the protrusion, which facilitates the disassembly and replacement of the sealing strip. Attached Figure Description
