[0030] 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.

[0031] like Figures 1-5As shown, this utility model provides an operable curtain wall sash, including a window frame assembly 1, a window sash assembly 2, and a support member 3. The window frame assembly 1 is fixedly connected to the building structure, and its interior can accommodate the window sash assembly 2, on which a glass body 4 is installed. The support member 3 includes a support rod 31 and a bracket 32. The bracket 32 ​​is fixed to the window frame assembly 1. One end of the support rod 31 is rotatably connected to the bracket 32, and the other end is rotatably connected to the window sash assembly 2. One side of the window sash assembly 2 is rotatably connected to the window frame assembly 1, allowing the window sash assembly 2 to have an open and closed state. The combination of the support rod 31 and the bracket 32 ​​forms an anti-fall device to prevent the operable sash from falling off in extreme conditions such as strong winds or earthquakes.

[0032] The operable sash of the curtain wall proposed in this utility model utilizes a rotatable connection between one side of the sash assembly 2 and the window frame assembly 1, while the other end of the support rod 31 is also rotatably connected to the sash assembly 2, allowing the sash assembly 2 to flexibly switch between an open and closed state. When the sash assembly 2 is in the open state, the support rod 31 and the bracket 32 ​​connect the sash assembly 2 to the window frame assembly 1, preventing the sash assembly 2 from falling off the window frame assembly 1. When the sash assembly 2 is in the closed state, the sash assembly 2 is housed in the window frame assembly 1, reducing the impact of wind load and improving the structural stability of the entire operable sash system.

[0033] It should be noted that, by Figure 1 As can be seen, the opening method of the window sash assembly 2 in the above embodiment is outward opening and top-hung. In other implementation methods, the opening method of the window sash assembly 2 can also be outward opening, inward opening, bottom-hung, etc. The corresponding structures of the curtain wall opening sash can be adjusted accordingly.

[0034] There are various structures for the rotatable connection between the window frame assembly 1 and the support rod 31. For example, it can be achieved through riveting, or through a multi-link structure, such as... Figure 2 and Figure 3 As shown, a first pin 11 is fixedly installed on the window frame assembly 1. The support rod 31 is rotatably connected to the window frame assembly 1 through the first pin 11. The front end of the support rod 31 is rotatably connected to the window frame assembly 1 through the first pin 11. The support rod 31 can rotate flexibly around the first pin 11, thereby providing smooth support and connection during the opening and closing of the window sash assembly 2. When the window sash assembly 2 is closed, it fits tightly with the window frame assembly 1. When the window sash assembly 2 is open, it provides sufficient tension.

[0035] It should be noted that one side of window sash assembly 2 is defined as the first side, and the other side is defined as the second side; the second side and the second side are not on the same side. For example... Figure 2 and Figure 3As shown, the first side is the top of the window sash assembly 2, and the second side is the bottom of the window sash assembly 2. It can be understood that in other embodiments, the first side can be the top and the second side can be the side. By simply making adaptive adjustments to the opening direction of the window sash assembly 2 and the connection position of the support rod 31, the window sash assembly 2 can be held in place by the support rod 31 when it is opened.

[0036] To improve the rotational flexibility of the support rod 31, a connector 33 is provided on the support 32. One end of the connector 33 is fixed to the support 32, and the other end is rotatably connected to the support rod 31. The connector 33 and the support rod 31 form a multi-link structure, which facilitates precise control of the rotation angle of the support rod 31, thereby achieving precise control of the opening angle of the window sash assembly 2. At the same time, it can be understood that the connector 33 provides a certain degree of adjustability between the window frame assembly 1 and the support rod 31, which facilitates fine-tuning according to different installation environments and building structures, improving the versatility and practicality of the operable sash.

[0037] There are several ways to fix the support 32 and the connector 33. For example, it can be fixed by welding, or by interference fit, etc. Figure 3 As shown, the support 32 is also provided with a set screw 321. The connector 33 is fixedly connected to the support 32 by the set screw 321. The installation process is simple, quick and easy to adjust. Just align the connector 33 with the corresponding position on the support 32 and then tighten the set screw 321 to complete the fixation.

[0038] Furthermore, a hinge shaft 311 is provided on the support rod 31. The hinge shaft 311 passes through the support rod 31 and the connector 33, allowing the support rod 31 and the connector 33 to be rotatably connected. The hinge shaft 311 tightly connects the support rod 31 and the connector 33 together, forming a stable rotating pair. This ensures that the support rod 31 can maintain a stable connection with the connector 33 while bearing the weight of the window sash assembly 2 and external loads, reducing the swaying and loosening of the support rod 31, thereby improving the stability of the entire opening sash device. Understandably, during installation, the connection state between the support rod 31 and the connector 33 can be adjusted by adjusting the position or tightness of the hinge shaft 311 to adapt to different installation environments and building structure requirements.

[0039] To enhance the structural strength of the operable sash, window sash assembly 2 is made of high-strength aluminum alloy profile with anodized surface treatment to improve corrosion resistance. The high-strength aluminum alloy material possesses high strength, capable of withstanding various forces encountered by window sash assembly 2 during opening, closing, and daily use, such as wind loads and its own weight. This ensures the stability of the window sash's shape and structure, enhancing the overall structural strength and rigidity.

[0040] According to another embodiment of the present invention, a second pin 12 is provided at the bottom of the window frame assembly 1, and the window sash assembly 2 is rotatably connected to the window frame assembly 1 through the second pin 12. The second pin 12 provides a stable rotation support point for the window sash assembly 2, ensuring that the window sash assembly 2 can remain stable during opening and closing, and reducing shaking and loosening.

[0041] According to another embodiment of this utility model, the window frame assembly 1 is provided with a multi-locking point structure 13, which is connected to the window sash assembly 2. When the window sash assembly 2 is in the closed state, it is housed inside the window frame assembly 1, and the multi-locking point structure 13 fixes it to the window frame assembly 1. The multi-locking point structure 13 provides support and fixation at multiple positions on the window sash assembly 2, enabling the window sash to be more stably fixed inside the window frame assembly 1 when closed. The multi-locking point structure 13, through the arrangement of multiple locking points, can evenly distribute the load (such as wind load, self-weight, etc.) on the window sash assembly 2 onto the window frame assembly 1, avoiding local stress concentration and reducing deformation of the window frame assembly 1 and the window sash assembly 2.

[0042] According to another embodiment of this utility model, a sealing strip (not shown in the figure) is provided around the window sash assembly 2. The sealing strip is used for waterproofing. The sealing strip is made of EPDM rubber, which has good elasticity and weather resistance. The elasticity of the sealing strip improves the sealing performance and prevents rainwater and air penetration. Figures 2-5 As shown, a waterproof component 21 is also provided at the connection point between the window frame assembly 1 and the window sash assembly 2 to prevent rainwater from seeping into the building interior through the gap at the connection point.

[0043] According to another embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the window frame assembly 1 is provided with an opening device 14. The opening device 14 is fixedly connected to the window frame assembly 1 by a fastener 141. It can be seen that the fastener 141 is a screw, which tightly fits the opening device 14 to the side of the window frame assembly 1.

[0044] The output end of the opening device 14 is connected to the window sash assembly 2 to drive the window sash assembly 2 to rotate. The opening device 14 is equipped with a motor and is electrically connected to the control device, so that the opening and closing of the window sash assembly 2 can be realized through remote control. At the same time, the electric opening device 14 can precisely control the opening angle of the window sash assembly 2 as needed, realizing multiple states of adjustment from slightly open to fully open, to meet different ventilation needs and usage scenarios.

[0045] In addition, the opening device 14 has an overload protection function. When encountering abnormal resistance or overload, the device will automatically stop operating to avoid equipment damage or safety accidents caused by overload, thus ensuring the safe use of the opening fan.

[0046] A buffer device is installed at the edge of the window frame assembly 1 of the operable sash to effectively absorb and mitigate the impact force during opening and closing, preventing damage to the window sash and frame due to collision and extending service life. Understandably, the buffer device can be made of rubber, springs, hydraulic dampers, etc.
