Description

Technical Field

[0001] This utility model relates to the field of fireproof window technology, and in particular to an automatically closing indicator fireproof warning window. Background Technology

[0002] Fire-resistant windows are special windows with important fire protection functions. Their frames and sashes are made of high-temperature resistant and non-flammable materials such as steel and aluminum alloys, and the glass is mostly fire-resistant glass. They can prevent the spread of fire and smoke during a fire, buy time for people to evacuate and reduce losses. They play a key role in places such as commercial buildings. Fire-resistant windows are classified into different types such as Class A, Class B and Class C according to their performance. During installation, they must strictly follow the specifications and standards, and should also be regularly maintained and inspected to ensure that they function properly.

[0003] Existing technologies, such as the utility model with publication number CN212296125U, disclose a fireproof protective window that can close automatically. This patent employs a guide pulley rotatably connected within a limiting groove. One end of the guide pulley is fixedly connected to a connecting seat, and one end of the connecting seat is fixedly connected to an electric telescopic rod. A rotating bracket is fixedly installed at the end of the electric telescopic rod away from the connecting seat, and a fixed plate is rotatably connected to one side of the rotating bracket. This utility model has a scientifically sound and reasonable structure, is safe and convenient to use, and utilizes the limiting groove, limiting seat, guide pulley, connecting seat, and electric telescopic rod. The rotating bracket and fixed plate can drive the aluminum alloy window frame to rotate by extending and shortening the electric telescopic rod during actual application, thereby realizing the automatic opening and closing of the aluminum alloy window frame. In addition, this automatic opening and closing method allows the fireproof window to close quickly in the event of a fire. At the same time, the fireproof window can also play a role in ventilation by automatically opening during actual use. This solves the problem that existing fireproof windows lack automatic closing function in actual application, which makes it difficult to quickly close the open fireproof window in the event of a fire, thus easily causing fire.

[0004] In the process of using automatic closing fireproof windows for fire prevention, most of the existing automatic closing fireproof windows on the market adopt an outward or inward opening design. When it comes to horizontally opening fireproof windows, the automatic closing mechanism used is difficult to effectively achieve horizontal closing movement. When the fireproof windows installed in the building are horizontally opening, the closing of the fireproof windows must be done manually, which leads to a weakening of the fire prevention effect of the fireproof windows. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing fire-resistant windows, where the horizontal opening type requires manual closing, thus weakening the fire-resistant effect. The invention proposes an automatically closing indicator fire warning window.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatically closing fire warning window, comprising an outer frame, a fixed window, and a closing assembly, wherein the fixed window is fixedly connected to the inner wall of the outer frame, a movable window is installed on the inner wall of the outer frame, and the closing assembly is disposed on the inner wall of the outer frame;

[0007] The closing assembly includes a drive unit, which includes a support frame. The support frame is fixedly connected to the inner wall of the outer frame. A servo motor is fixedly connected to the upper surface of the support frame. A transmission gear is bolted to the drive end of the servo motor. A driven gear ring is installed on the inner wall of the outer frame. The transmission gear meshes with the tooth groove of the driven gear ring. A rotating hole is opened on the inner wall of the outer frame. A bidirectional lead screw is rotatably connected to the inner wall of the rotating hole. The driven gear ring is fixedly connected to the arc surface of the bidirectional lead screw. A limit plate is fixedly connected to the inner wall of the outer frame. A guide post is fixedly connected to the surface of the limit plate.

[0008] The closing assembly further includes a linkage unit, which includes a linkage frame. The linkage frame is threadedly connected to the surface of a bidirectional lead screw. The linkage frame is in contact with the inner wall of the outer frame. A U-shaped block is fixedly connected to the side surface of the linkage frame. A circular hole is opened on the surface of the U-shaped block. A first rotating shaft is rotatably connected to the inner wall of the circular hole. A connecting arm is fixedly connected to the arc surface of the first rotating shaft. A second rotating shaft is fixedly connected to the end of the connecting arm away from the first rotating shaft. A positioning frame is fixedly connected to the side surface of the movable window. A clamping plate is fixedly connected to the lower surface of the positioning frame. A through hole is opened on the surface of the clamping plate. The second rotating shaft is rotatably connected to the inner wall of the through hole.

[0009] Preferably, the transmission gear is located on the inner wall of the support frame, and the driven gear ring has a stepped design. Through the cooperation of the transmission gear and the driven gear ring, the bidirectional lead screw can be driven to rotate under the drive of the servo motor.

[0010] Preferably, the bidirectional lead screw passes through the upper surface of the outer frame and can rotate under the drive of the driven gear ring, thereby engaging with the linkage frame on the upper and lower sides and realizing the adjustment operation of the linkage frame position.

[0011] Preferably, there are two limiting plates, which are arranged symmetrically about the bidirectional lead screw. The limiting plates are sleeved on the surface of the bidirectional lead screw. The limiting plates can support and restrict the position of the guide column, thereby ensuring the stability of the guide column in use.

[0012] Preferably, the linkage frame is slidably connected to the surface of the guide column, and there are two linkage frames. The two linkage frames are arranged symmetrically about the bidirectional lead screw. The guide column can guide the movement direction of the linkage frame to ensure the stability of the linkage frame in the moving state.

[0013] Preferably, there are two connecting arms, which are arranged symmetrically about the movable window. The clamp is fixedly connected to the side surface of the movable window. The U-shaped block and the clamp can be connected by the cooperation of the connecting arms with the first and second rotating shafts, so that the U-shaped block can drive the clamp to move.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting a closing component, when the fireproof window needs to close automatically, an external power source supplies power to the servo motor. The servo motor drives the transmission gear, which meshes with the driven gear ring. The driven gear ring drives the bidirectional lead screw to rotate clockwise. While rotating, the bidirectional lead screw meshes with the upper and lower linkage frames. Guided by the guide column and the outer frame, the linkage frames open to the upper and lower sides. At the same time, the linkage frames, in conjunction with the U-shaped block, drive the first rotating shaft and the connecting arm. The connecting arm, under force, cooperates with the second rotating shaft to push the clamping plate. The clamping plate, under force, cooperates with the positioning frame to push the movable window. The movable window is displaced and gradually closes. When the linkage frames move to the maximum distance, the servo motor stops working, and the movable window is completely closed. It also cooperates with the fixed window to seal the outer frame. By setting the closing component, the automatic closing effect of the sliding fireproof window is enhanced, thereby reducing the need for manual operation when the sliding fireproof window is automatically closing, and further improving the fireproof effect of the protective window.

[0026] Specifically, the transmission gear 413 is located on the inner wall of the support frame 411, and the driven gear ring 414 has a stepped design.
