[0002] High-speed doors are widely used in modern industrial and commercial settings. They can open and close quickly, meeting the needs of rapid passage for people and goods and effectively improving work efficiency.

[0003] However, existing high-speed doors have shortcomings in terms of airtightness. The gaps at the contact points between the door curtain and the door frame are too large, making it easy for air to leak. Moreover, the bottom of the door curtain is difficult to fit tightly against the ground. During long-term use, due to uneven ground or wear and tear on the door curtain, the gaps will further increase, making it impossible to guarantee airtightness. Utility Model Content

[0004] The purpose of this invention is to provide a high-airtightness, high-speed door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0021] 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.

[0022] Please see Figures 1-6 In this embodiment of the utility model, a high airtightness high-speed door includes a column 1, a curtain 2 and a roller shutter mechanism 3. There are two columns 1, which are arranged opposite each other on both sides of the curtain 2. The roller shutter mechanism 3 is fixedly connected to the top of the column 1. A first sealing mechanism 4 is provided at the contact position between the two columns 1 and the roller shutter mechanism 3 and the curtain 2. A second sealing mechanism 5 is provided at the lower end of the curtain 2.

[0023] like Figure 4 As shown, the column 1 is composed of a front upright plate 11 and a rear upright plate 12. The front upright plate 11 and the rear upright plate 12 are similar to a U-shaped structure. The inner walls of the end 111 of the front upright plate 11 and the end 121 of the rear upright plate 12 overlap and are fixedly connected by bolts. The free ends 112 of the front upright plate 11 and the free ends 122 of the rear upright plate 12 are arranged opposite each other and left with a certain distance to form a card interface 13 for the curtain 2 to pass through. The distance of the card interface 13 is greater than the width of the curtain 2.

[0024] A connecting plate 14 is fixedly connected inside the column 1. A slide rail 15 is fixedly connected to the connecting plate 14. A slider 16 is slidably connected inside the slide rail 15. The slider 16 is fixedly connected to the curtain 2.

[0025] like Figure 2 and Figure 3 As shown, the roller shutter mechanism 3 includes a head cover 31, which is fixedly connected to the upper ends of two columns 1. A through groove 311 for the curtain 2 to pass through is provided on the bottom wall of the head cover 31. The through groove 311 is positioned opposite to the card interface 13.

[0026] like Figure 5 As shown, the first sealing mechanism 4 is a sealing strip 41 fixedly connected to the free ends 112, 122 and the inner wall of the through groove 311. The sealing strip 41 at the upper end of the free ends 112, 122 on both sides is connected to the sealing strip 41 at both ends of the through groove 311 to achieve high airtightness on both sides and above of the high-speed door.

[0027] like Figure 6As shown, the second sealing mechanism 5 includes a bottom beam bag 51, a bottom beam counterweight 52, an inner sealing curtain 53, and an outer sealing curtain 54. The bottom beam bag 51 is formed by folding the lower end of the door curtain 2 and heat-sealing it with the door curtain 2. The bottom beam counterweight 52 is installed inside the bottom beam bag 51. When the door curtain 2 is closed, the bottom of the door curtain 2 abuts against the ground under the gravity of the bottom beam counterweight 52, ensuring the airtightness of the bottom of the high-speed door. In order to increase the contact area between the bottom of the door curtain 2 and the ground, the inner sealing curtain 53 and the outer sealing curtain 54 are fixedly connected to the front and rear sides of the bottom beam bag 51. The upper ends of the inner sealing curtain 53 and the outer sealing curtain 54 are heat-sealed to the bottom beam bag 51, and the lower ends are free ends. When the door curtain 2 is closed, the lower ends of the inner sealing curtain 53 and the outer sealing curtain 54 abut against the ground, increasing the contact area.

[0028] like Figure 4 As shown, the roller blind mechanism 3 also includes a rotating shaft 32, a motor 33 and a motor cover 34. The rotating shaft 32 is rotatably connected inside the head cover 31. The door curtain 2 is installed on the rotating shaft 32. One end of the rotating shaft 32 is fixedly connected to the output end of the motor 33. The motor 33 is fixedly connected to the head cover 31. The motor cover 34 is provided outside the motor 33 and is fixedly connected to the head cover 31.

[0029] The working principle of this utility model is as follows: When the high-speed door needs to be opened, the motor 33 starts, and the output end of the motor 33 drives the rotating shaft 32 to rotate. Since the door curtain 2 is installed on the rotating shaft 32, the rotation of the rotating shaft 32 causes the door curtain 2 to roll up around the rotating shaft 32. Through the through groove 311 of the motor head cover 31, the door curtain 2 moves upward along the slide rail 15 on the column 1, driven by the slider 16, to realize the opening action of the high-speed door. When closing, the motor 33 reverses, and the door curtain 2 moves downward along the slide rail 15 under the control of gravity and the motor 33 until the bottom beam bag 51 at the bottom of the door curtain 2 abuts against the ground under the gravity of the bottom beam counterweight 52, thus completing the closing action. This high-speed door forms a continuous sealing structure by installing sealing strips 41 on the free ends 112 and 122 of the column 1 and on the inner wall of the through groove 311. The sealing strips 41 at the upper ends of the free ends 112 and 122 on both sides are connected to the sealing strips 41 at both ends of the through groove 311. This tightly fits the curtain 2, reduces air exchange on both sides of the curtain 2, and improves the airtightness of the high-speed door on both sides and above. By installing a second sealing mechanism 5 at the lower end of the curtain 2, the curtain 2 can contact the ground when the high-speed door is closed. The inner sealing curtain 53 and outer sealing curtain 54 on the front and rear sides of the bottom beam bag 51 increase the contact area with the ground, preventing air from entering the high-speed door through the lower end of the curtain 2, and further improving the airtightness of the high-speed door.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
