[0002] Three-wing revolving doors, with their simple, beautiful, and economical design, are widely used in office buildings, hotels, shopping malls, airports, and other places. They simultaneously address the seemingly contradictory requirements of building entrance accessibility and environmental isolation, effectively providing windproofing, dustproofing, and sound insulation, thereby improving the environment near the entrance. When combined with display cases, they further enhance the decorative effect. Three-wing revolving doors are suitable for buildings with high pedestrian traffic, offering ample space, strong passage capacity, and providing a safe and comfortable passageway, making them suitable for airports, shopping malls, and government institutions.

[0003] Three-wing revolving doors have been used in the market for many years and are loved by many customers because of their lightweight structure and flexible rotation. However, in the design of building structures, the height of a large number of door openings is limited, resulting in a relatively low overall height of the door. Traditional revolving doors are limited by the overall size of the structure and motor, and the door header can usually only be 300mm, which reduces the passage height of the door and affects the passage of people. Therefore, a three-wing door drive structure is proposed. Utility Model Content

[0027] Example

[0028] Please see Figure 1-7 This utility model provides a technical solution: a three-wing door drive structure, including a column 1, a revolving door header 2 installed on the top of the column 1, a beam 3 installed inside the revolving door header 2, and a drive assembly set on the beam 3; through the design of the drive assembly, the height of the revolving door header 2 can be reduced, so that the three-wing door is not limited by the overall size of the structure and motor, and the passage height of the revolving door can be increased, greatly improving the practicality of the revolving door. At the same time, the drive assembly has a compact structure, smooth deceleration operation, and small transmission gap through belt and gear meshing transmission, effectively avoiding the shaking phenomenon when the door leaf 6 rotates;

[0029] The drive assembly includes a fixed base 4, a rotating shaft 5, and three door panels 6. The fixed base 4 is installed at the bottom of the main beam 3. The rotating shaft 5 is rotatably connected to the fixed base 4. The three door panels 6 are installed on the outside of the rotating shaft 5. Each of the three door panels 6 has a mounting component on its bottom side. A driven gear 7 is fixedly sleeved on the top outer side of the rotating shaft 5. A connecting base 12 is installed on the inner side of the main beam 3. A connecting shaft 9 is installed on the connecting base 12. A driving gear 10 is installed at the bottom outer side of the connecting shaft 9. A driven pulley 13 is installed at the top outer side of the connecting shaft 9. A drive motor 8 is installed on the top of the fixed base 4. A driving pulley 13 is installed on the output shaft of the drive motor 8. The drive gear 10 is meshed with the drive belt 11 on the outside of the driven gear 7. The drive belt 11 and the driven belt 13 are connected by a belt. By connecting the power supply to the drive motor 8, the drive motor 8 is started. The output shaft of the drive motor 8 drives the drive belt 11 to rotate. The drive belt 11 drives the driven belt 13 to rotate through the belt. Then, the driven belt 13 drives the drive gear 10 to rotate through the connecting shaft 9. This causes the drive gear 10 to drive the driven belt 13 to rotate on the top of the fixed base 4. During the rotation of the drive gear 10, the door leaf 6 is driven to rotate through the rotating shaft 5, thus completing the normal operation of the three-wing door.

[0030] By setting up the installation components, the sweeping strip 15 can be disassembled and replaced easily, saving time and effort. The installation components include a first groove 14 and a sweeping strip 15. The first groove 14 is located at the bottom of the door leaf 6, and the sweeping strip 15 is installed inside the first groove 14. One end of the first groove 14 has a slot 16. One end of the bottom of the door leaf 6 has a second groove 17. A U-shaped frame 18 is installed on one side of the second groove 17 at the bottom of the door leaf 6. A plug 19 is movably inserted through the inner side of the U-shaped frame 18, and a tension spring 20 is movably sleeved on the outer side of the plug 19. A limit plate 21 is set inside the second groove 17. One end of the limit plate 21 has a groove 22. A connecting block 23 is fixedly connected to one side of the limit plate 21. One side of the connecting block 23 has a groove 22. A limiting groove 24 is provided, and a groove 22 is sleeved on the outside of the first groove 14. One end of the sweeping strip 15 abuts against the bottom side of the groove 22. One end of the insert post 19 matches the limiting groove 24, and one end of the insert post 19 is movably inserted into the limiting groove 24. By pulling one end of the insert post 19, the insert post 19 moves out of the limiting groove 24 on the connecting block 23. At this time, pull one end of the limiting plate 21 downward and move it downward. When one end of the limiting plate 21 moves out of the second groove 17, pull the limiting plate 21 to one end, and one end of the limiting plate 21 moves away from the inside of the slot 16. At the same time, the first groove 14 is disengaged from the groove 22, and the limiting plate 21 can be disassembled. Then, the sweeping strip 15 inside the first groove 14 can be pulled out and replaced.

[0031] To facilitate the installation of the sweeping strip 15, one end of the tension spring 20 is fixedly connected to the outside of the U-shaped frame 18, and the other end of the tension spring 20 is fixedly connected to the outside of the insert post 19. During installation, by pulling one end of the insert post 19, the tension spring 20 is stretched, and the limiting plate 21 is installed inside the second groove 17. When the insert post 19 is released, the tension spring 20 will drive the insert post 19 to reset, and one end of the insert post 19 will be inserted into the inside of the limiting groove 24, thus completing the installation of the limiting plate 21. The operation is simple and quick.

[0032] The working principle or structural principle is as follows: When the three-wing door rotates, the power supply to the drive motor 8 is connected, controlling the drive motor 8 to start. The output shaft of the drive motor 8 drives the active belt pulley 11 to rotate. The active belt pulley 11 drives the driven belt pulley 13 to rotate via the belt. Then, the driven belt pulley 13 drives the active gear 10 to rotate via the connecting shaft 9, so that the active gear 10 drives the driven belt pulley 13 to rotate on the top of the fixed base 4. During the rotation of the active gear 10, the door leaf 6 is driven to rotate via the rotating shaft 5, thus completing the normal operation of the three-wing door. Through the design of the drive component, the height of the revolving door header 2 can be reduced, so that the three-wing door is not limited by the overall size of the structure and motor, and the passage height of the revolving door can be increased, greatly improving the practicality of the revolving door. At the same time, the drive component has a compact structure and smooth deceleration operation. Through the meshing transmission of belt and gear, the transmission gap is small, effectively avoiding the shaking phenomenon that occurs when the door leaf 6 rotates.

[0033] When the sweeping strip 15 needs to be replaced, by pulling one end of the insert post 19, the tension spring 20 is stretched and the insert post 19 moves out of the limiting groove 24 on the connecting block 23. At this time, pull one end of the limiting plate 21 downward and move it downward. When one end of the limiting plate 21 moves out of the interior of the second groove 17, pull the limiting plate 21 to one end. One end of the limiting plate 21 moves away from the interior of the slot 16. At the same time, the first groove 14 disengages from the groove 22, and the limiting plate 21 can be disassembled. Then, the sweeping strip 15 inside the first groove 14 can be pulled out to complete the disassembly and replacement of the sweeping strip 15.
