Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and specifically discloses a building window with a multiple locking structure. Background Technology

[0002] With the increasing development of modern architecture, building windows, while providing lighting and ventilation, must also possess good safety and practicality. Currently, common building windows on the market typically employ a single locking structure, such as traditional window latches or ordinary handle locking devices. While these devices provide basic safety in daily use, they still have some shortcomings in practical applications, especially when facing sudden external forces, strong winds, or external impacts, where the safety and stability of the window are often insufficiently guaranteed. The safety problems of traditional windows mainly focus on two aspects: First, a single locking structure may not be able to guarantee the secure fixation of the window sash in extreme weather or emergencies, especially when the window is impacted by strong external winds, easily leading to loosening or deformation of the sash; second, existing windows lack effective anti-fall designs, especially in high-rise buildings, where the risk of accidental window sash detachment is high, potentially posing serious safety hazards to pedestrians or the surrounding environment. Therefore, designing a building window with a multi-locking structure and anti-fall function has become an urgent need to improve building safety performance. An existing window with a roller shutter (Publication No.: CN105041121A) has at least the following drawbacks:

[0003] 1. Existing windows lack a multi-locking structure, thus failing to provide multiple layers of protection during use. If a single locking device fails, the window sash may pose a significant security risk due to the lack of additional safety features. Therefore, a multi-locking structure is urgently needed.

[0004] 2. Most existing building windows lack fall protection design, especially in high-rise buildings. When the window sash is opened or repaired by external force, without fall protection device, the window sash may fall off accidentally, posing a significant safety risk and affecting the safety of the building and people. Therefore, there is an urgent need for a device with fall protection design. Utility Model Content

[0005] The main objective of this invention is to provide a building window with a multi-locking structure, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a building window with a multi-locking structure, including a building window body, a window handle lock installed in front of the building window body, a bolt lock installed above the building window body, a bolt post installed on the bolt lock, an anti-fall limiting plate installed in front of the building window body, the bolt lock being welded together, and the building window body being detachable.

[0007] Preferably, the building window body adopts a rounded corner design.

[0008] Preferably, the anti-fall limiting plate is connected by welding.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. This utility model combines a bolt lock and a window handle lock to achieve double locking, greatly improving window security. Even if one locking method fails, the other locking method can still work effectively, ensuring that the window sash is firmly fixed in the frame and reducing the risk of the window sash loosening or falling off due to strong external winds, impacts, or accidental collisions.

[0011] 2. In high-rise buildings, the accidental detachment of window sashes can pose a significant safety hazard to pedestrians or the surrounding environment. By installing anti-fall limiting plates on the windows, even if the window sash is accidentally opened during maintenance or cleaning, or affected by strong external winds, the limiting plates can promptly restrict the opening of the window sash, preventing it from falling and effectively improving the safety of high-rise buildings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] A building window with a multi-locking structure includes a building window body, a window handle lock installed at the front of the building window body, a bolt latch installed at the top of the building window body, a bolt post installed on the bolt latch, and an anti-fall limiting plate installed at the front of the building window body. The bolt latch is welded together, the building window body is detachable, the building window body has rounded corners, and the anti-fall limiting plate is welded together.

[0022] It should be noted that this utility model achieves double locking by combining a bolt lock and a window handle lock. Compared with existing single locking methods, this utility model can significantly improve the stability and protective capability of windows under special conditions such as strong winds and external impacts. The following specific data demonstrates its superiority: In a strong wind simulation experiment with a wind speed of 50 km / h, the window with a single locking method showed obvious loosening of the window sash after 10 strong wind impacts, requiring relocking. However, the window with double locking using this utility model, under the same experimental conditions, remained stable after 30 strong wind impacts, with no signs of loosening in the locking device, and the force distribution on the window sash was more even. This experiment shows that the wind resistance performance of this utility model in strong wind environments is improved by nearly 3 times. Applying an external force of 50 kg to the window sash, the locking device of the window with a single locking method partially disengaged after 3 impacts, reducing the seal between the frame and the window sash; while the double locking structure of this utility model remained intact after 10 impacts with the same external force, and the window sash remained firm without loosening. This indicates that the impact resistance of this invention is improved by more than 2 times. After 3000 window opening and closing tests, the wear rate of the latch and window frame contact point of a single-locking window reached as high as 0.5 mm after repeated use, resulting in a weakened locking effect; while the wear rate of the double-locking structure of this invention was controlled within 0.2 mm under the same test, improving durability by about 2.5 times and significantly extending the service life of the window. For high-rise buildings, accidental window sash detachment may pose a serious safety hazard to pedestrians or the surrounding environment. This invention effectively prevents the window sash from accidentally detaching due to external force or misoperation by installing an anti-fall limit plate on the window. The following experimental data demonstrates the superiority of this invention in high-rise buildings: In a 50-meter high-altitude simulation experiment, the window sash without the anti-fall limit plate completely detached from the window frame after being opened by external force, with a 70% probability of accidental fall, posing a great safety hazard. Windows equipped with anti-fall limiting plates, under the same external force, firmly confine the window sash within a safe range, with a 0% probability of sash detachment. This data demonstrates the significant advantage of this invention in preventing window sash detachment. Strong wind safety tests were conducted on high-rise building windows at 60 km / h. Traditional windows, lacking anti-fall limiting designs, experienced a displacement of approximately 10 mm within 10 minutes, easily leading to sash detachment from the frame. The windows of this invention, after the same period of strong wind testing, exhibited displacement controlled within 3 mm, effectively limiting the sash's movement range through the limiting plates, ensuring its safety and stability. In a simulated maintenance scenario, operators cleaned windows on the 10th floor. Windows without anti-fall limiting plates experienced sash detachment due to external force during cleaning, with an accident rate of 15%. Windows equipped with anti-fall limiting plates, under the same conditions, did not experience sash detachment, with an accident rate of 0%.This data shows that the present invention greatly improves the safety and reliability of windows in high-rise buildings.

[0023] It should be noted that the table below is a comparison of experimental data between this utility model and traditional equipment:
