[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figure 1 As shown, this utility model provides a smoke curtain wall covering fixing device, including a curtain body 1, a top plate 2 fixedly installed at the upper end of the curtain body 1, positioning side plates 3 installed at both ends of the top plate 2, positioning holes opened at the ends of the positioning side plates 3, wall covering 4 provided on the front of the curtain body 1, a driving device 5 movably installed at the upper end of the wall covering 4, a fixing iron block 6 fixedly installed at the lower end of the curtain body 1 through a support plate, a magnetic stone 7 magnetically attracted to the top of the fixing iron block 6, and guide limiting frames 9 sleeved on both sides of the wall covering 4.

[0025] This technical solution uses the magnetic stone 7 at the lower end of the wall covering 4 to magnetically attract the fixed iron block 6. This fixing method ensures that the wall covering 4 is stably in the working position after being lowered, and is not easily shaken or displaced by external forces such as smoke flow or airflow, thus ensuring the smoke blocking effect. The guide limit brackets 9 on both sides of the wall covering 4 can constrain and guide the wall covering 4, preventing problems such as displacement and wrinkles during the opening and closing of the wall covering 4, further enhancing the stability and fixing effect of the wall covering 4. The magnetic stone 7 and the wall covering 4 are relatively easy to be damaged. Due to the use of magnetic attraction and sleeve connection methods, these components can be easily replaced individually when damaged, without the need to replace the entire smoke curtain device.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, side baffles 8 are fixedly installed on both sides of the vertical wall body 1, and rubber filling pads 10 are adhered to the inner wall of the guide limit frame 9. The back of the rubber filling pads 10 is in contact with the surface of the end of the wall fabric 4. Connecting springs 12 are installed at both the upper and lower ends of the front of the guide limit frame 9. An adjusting plate 11 is fixedly installed at the front end of the connecting spring 12, and the outer end of the adjusting plate 11 is rotatably installed with the front end of the side baffles 8.

[0028] Adopting such Figure 1 The technical solution shown has side baffles 8 fixedly installed on both sides of the smoke curtain body 1 to prevent smoke from escaping from the sides of the smoke curtain body 1, thus enhancing the overall smoke blocking effect. In the event of a fire, it can effectively block the smoke from spreading to the side, making the smoke blocking area more concentrated and improving the smoke curtain's ability to protect specific areas. The rubber filling pad 10 bonded to the inner wall of the guide limit frame 9 contacts the end surface of the wall fabric 4, which can play a role in buffering and sealing, reducing the friction between the wall fabric 4 and the guide limit frame 9, preventing the wall fabric 4 from being damaged during frequent opening and closing, and extending the service life of the wall fabric 4.

[0029] Secondly, in the technical solution, a rubber pressing pad 13 is installed on the inner wall of the inner end of the adjusting plate 11, and the back of the rubber pressing pad 13 is in contact with the front of the wall cloth 4; a sealing filling pad 14 is fixedly installed on the top of the top plate 2, and the upper end of the sealing filling pad 14 is higher than the horizontal height of the top of the positioning side plate 3.

[0030] Its adoption is as follows Figure 1 The technical solution shown has a rubber material with a certain elasticity and friction of the rubber pressing pad 13, which can apply uniform pressure to the wall cloth 4 and further enhance the fixation of the wall cloth 4 in the device. This can effectively prevent the wall cloth 4 from shifting or shaking when affected by external forces such as airflow and vibration, and ensure that the wall cloth 4 is always in a stable working state, thereby improving the stability of the smoke blocking effect.

[0031] Example 3:

[0032] This utility model is as follows Figures 1-4 As shown, the positioning side plate 3 and the top plate 2 are integrally formed, and the positioning hole on the positioning side plate 3 is a rectangular through hole; the driving device 5 includes a motor and a roller, the output shaft of the motor is connected to the roller for transmission, and the upper end of the wall cloth 4 is wound on the roller; the support plate at the lower end of the vertical wall body 1 is fixedly connected by bolts, and the fixing iron block 6 is located on the front of the vertical wall body 1.

[0033] By adopting the above technical solution, the positioning side plate 3 and the top plate 2 adopt an integral molding structure, which significantly enhances the overall structural strength and stability of the device. The integral molding avoids problems such as loose connections and gaps that may exist in the assembled structure, and can better withstand external pressure and impact. It ensures that the device will not affect the smoke blocking effect due to structural problems during long-term use. At the same time, the integral molding design reduces the number of processes in the production and installation process, improves production efficiency, and also reduces the difficulty and cost of installation.

[0034] The working principle of this utility model is as follows: After the motor in the drive device 5 starts, the motor output shaft drives the roller to rotate. Since the upper end of the wallpaper 4 is wound on the roller, the rotation of the roller can realize the winding and unwinding operation of the wallpaper 4. Under normal circumstances, the motor can control the roller to roll up the wallpaper 4, thus not occupying too much space. In case of emergency such as fire, the motor reverses and quickly lowers the wallpaper 4, allowing it to unfold quickly and play a role in blocking smoke. The magnetic stone 7 at the lower end of the wallpaper 4 is magnetically attracted to the fixed iron block 6. When the wallpaper 4 is lowered, the magnetic attraction makes the lower end of the wallpaper 4 firmly fixed to the bottom of the wall hanging body 1, preventing the wallpaper 4 from shaking or shifting. The rubber filling on the inner wall of the guide limit frame 9 The padding pad 10 contacts the end surface of the wallpaper 4. The rubber padding pad 10 not only reduces the friction between the wallpaper 4 and the guide limit frame 9, but also plays a certain sealing role to prevent smoke from leaking from both sides of the wallpaper 4. At the same time, the guide limit frame 9 can guide the wallpaper 4 to remain vertical and neat during the unfolding and retraction process, avoiding wrinkles or displacement of the wallpaper 4. When the wallpaper 4 is displaced due to tension changes or external forces during the unfolding and retraction process, the connecting spring 12 will stretch and deform, driving the adjusting plate 11 to rotate, so that the rubber pressing pad 13 applies appropriate pressure to the wallpaper 4, ensuring that the wallpaper 4 is always in the correct position, while buffering the impact force on the wallpaper 4 and protecting the wallpaper 4 from damage.
