[0025] Example
[0026] In the prior art, when the rolling door is retracted or extended, it is driven by motors, and the speed of these motors is generally low. Therefore, after a fire occurs, the low-speed motor will prolong the closing time of the rolling door, thereby increasing the risk of fire spreading. What's worse, the fire will cut off the power supply, causing the rolling door to lose the closing power and unable to complete closing.
[0027] See also Figure 1-6The utility model provides a technical solution: a vertical lifting fireproof rolling shutter door, comprising a vertical fireproof rolling shutter door body 1, a lock core for anti-theft is arranged on the surface of the vertical fireproof rolling shutter door body 1, a handle 2 for convenient grasping of the door body is symmetrically fixed on the surface of the vertical fireproof rolling shutter door body 1, a protective shell 3 is fixed on the surface of the vertical fireproof rolling shutter door body 1, a winding assembly 4 is arranged on the surface of the winding assembly 4, an output device 5 is arranged on the surface of the output device 5, a bearing structure 6 is arranged on the surface of the bearing structure 6, a limiting mechanism 7 is arranged on the surface of the bearing structure 6, the limiting mechanism 7 is connected to the vertical fireproof rolling shutter door body 1, and a driving part is arranged on the surface of the limiting mechanism 7 Component 8. In order to provide heat dissipation protection for the motor 502, heat dissipation holes are provided on the surface of the protective shell 3, and the heat dissipation holes are evenly spaced on the protective shell 3. In order to retract and extend the rolling shutter door, a winding component 4 is provided. The winding component 4 includes a rotating shaft 401 and a slot 402. A rotating shaft 401 is provided on the surface of the vertical fireproof rolling shutter door body 1, and a slot 402 is provided at the end of the rotating shaft 401. In order to realize electric retraction and reduce the amount of labor consumed by the user when opening or closing the door body in daily life, an output device 5 is provided. The output device 5 includes an insertion rod 501 and a motor 502. The internal snap-fit sliding connection of the slot 402 is connected with the insertion rod 501, and the motor 502 is fixed at the end of the insertion rod 501.
[0028] In order to place the motor 502 so that it can work smoothly, a bearing structure 6 is provided, and the bearing structure 6 includes a support plate 601 and a connecting plate 602. The support plate 601 is fixed to the bottom of the motor 502, and the support plate 601 fits with the protective shell 3. The support plate 601 and the protective shell 3 fit together so that the motor 502 is in a relatively closed space, thereby protecting the motor 502 and extending its service life. A connecting plate 602 is fixed to the bottom of the support plate 601. In order to limit the connecting plate 602 so that it can keep moving smoothly, a limiting mechanism 7 is provided. The limiting mechanism 7 includes a slide bar 701 and a vertical plate 702. The slide bar 701 is installed through the interior of the connecting plate 602, and the vertical plate 702 is fixed at the end of the slide bar 701. The plate 702 is fixed to the vertical fire shutter door body 1. In order to provide a power source for the displacement of the connecting plate 602, thereby separating the motor 502 from the rotating shaft 401, and facilitating personnel to quickly close the vertical fire shutter door body 1, a driving component 8 is provided. The driving component 8 includes a screw 801 and a knob 802. The surface bearing of the vertical plate 702 is connected to the screw 801, and the end of the screw 801 passes through the interior of the connecting plate 602. The end of the screw 801 is fixed with a knob 802. In order to reduce the time for rotating the knob 802, the thread spacing on the surface of the screw 801 is large. This design enables the screw 801 to drive the connecting plate 602 to move a long distance without having to rotate at a large angle, thereby realizing the rapid separation of the insertion rod 501 and the slot 402 and reducing the driving time.
[0029] The model of the motor 502 is 5D120RGA-RV.
[0030] According to the working principle or structural principle, in daily use, the staff can use the motor 502 to drive the rotating shaft 401 to rotate, so as to retract and extend the door body, so that the staff can open and close the door without human drive, which greatly reduces the daily labor. If a fire occurs, the staff needs to quickly close the door body or cut off the power supply due to the fire, so that the vertical fire shutter door body 1 cannot be closed. At this time, the staff can drive the screw 801 to rotate through the knob 802. Because the screw 801 is threadedly connected to the connecting plate 602, when the screw 801 rotates, The threads on the surface of the screw 801 will drive the connecting plate 602 to move. Because the connecting plate 602 and the support plate 601 are fixed to each other, when the connecting plate 602 is displaced, it will drive the support plate 601 to move synchronously, and then the fixed motor 502 on the support plate 601 will also move in the same direction, so that the plug rod 501 on the output shaft of the motor 502 is disconnected from the slot 402, that is, the motor 502 with a self-locking function no longer limits the rotating shaft 401, and the door body can be driven to be retracted and released by external forces. At this time, the staff can use the handle 2 to quickly close the door body.
[0031] In summary, the device has the advantages of quick closing and simple structure.
