Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a fireproof rolling shutter door with a stable structure, comprising a shell 1, a controller 2 is installed on one side surface of the shell 1, a rolling shutter mechanism 3 is arranged on the inner surface of the shell 1, a guide rail 4 is fixedly connected to the lower surface of the shell 1, and a door panel mechanism 5 is arranged on the inner surface of the guide rail 4;

[0019] The rolling shutter mechanism 3 includes a rotating shaft 301, a gearbox 302, a driving motor 303, a hinge plate 304, a fixed plate 305 and a groove plate 306. The inner surface of the housing 1 is rotatably connected with the rotating shaft 301, one end of the rotating shaft 301 is mounted with the gearbox 302, one side surface of the gearbox 302 is mounted with the driving motor 303, the outer surface of the rotating shaft 301 is fixedly connected with the fixed plate 305, one end of the rotating shaft 301 is rotatably connected with the fixed plate 305, and one side surface of the fixed plate 305 is fixedly connected with the groove plate 306;

[0020] The door panel mechanism 5 includes a sliding groove 501, a sliding block 502, a door panel 503, a hinge 504, a base 505, a limit block 506 and a clamping plate 507. The inner surface of the guide rail 4 is provided with a sliding groove 501, the inner surface of the sliding groove 501 is slidably connected with the sliding block 502, one side surface of the sliding block 502 is fixedly connected with the door panel 503, the outer surface of the door panel 503 is fixedly connected with the hinge 504, and the lower surface of the door panel 503 is fixedly connected with the base 505. The other end of the door panel 503 is fixedly connected to a limit block 506, and the outer surface of the limit block 506 is slidably connected to a clamping plate 507. Through the setting of the rolling shutter mechanism 3 and the door panel mechanism 5, when in use, the drive motor 303 is started, and the drive motor 303 drives the rotating shaft 301 to rotate through the gearbox 302. The gearbox 302 can change the speed of the drive motor 303 so that it can adapt to different situations. The rotation of the rotating shaft 301 drives the hinge plate 304 to rotate, and the hinge plate 30 A hinge 504 is fixed at one end of the hinge plate 304. When the hinge plate 304 rotates, the hinge 504 can be pulled, and the groove plate 306 can limit the door panel 503 so that the door panel 503 can be rolled into the housing 1. The driving motors 303 on both sides are started at the same time, and the hinge 504 drives the door panel 503 to roll up the curtain, and the sliding block 502 will slide in the sliding groove 501. The hinge 504 can also drive the limit block 506 and the clamping plate 507 to roll up the curtain, so that all the door panels 503 can be rolled into the housing 1. 3 The rolling shutter enters the housing 1. When only one side of the driving motor 303 is started, the hinge 504 drives one side of the door panel 503 to roll up the shutter, and the clamping plate 507 will be pressed by the base 505 and will not move, so that one side of the door panel 503 can be rolled up. At this time, the limit block 506 will slide in the clamping plate 507, and the clamping plate 507 will limit the limit block 506, acting as a guide rail 4, which will not affect the use of the rolling shutter door. Even if one side of the door panel 503 is damaged, it will not waste rescue time.

[0021] Furthermore, the rotating shaft 301 is symmetrically arranged with respect to the central axis of the outer shell 1, and two groups of hinge plates 304 are evenly spaced on the outer surface of the rotating shaft 301. Through the arrangement of the rotating shaft 301, when in use, the driving motors 303 on the left and right sides can be started at the same time through the controller 2, or a single driving motor 303 can be started to drive the door panel 503 on one side to pull the rolling shutter.

[0022] Furthermore, the inner wall size of the sliding groove 501 is consistent with the outer wall size of the sliding block 502, and two groups of hinges 504 are arranged at equal intervals on the outer surface of the door panel 503. Through the setting of the sliding groove 501 and the sliding block 502, when in use, the sliding block 502 slides in the sliding groove 501, and the sliding groove 501 will limit the sliding block 502, so that the sliding of the sliding block 502 is more stable.

[0023] Furthermore, one end of the hinge 504 is fixedly connected to the hinge plate 304, and the outer wall size of the limit block 506 is consistent with the inner wall size of the splint 507. Through the setting of the limit block 506 and the splint 507, when in use, the limit block 506 will slide in the splint 507, and the splint 507 will limit the limit block 506, making the sliding of the limit block 506 more stable.

[0024] Working principle: Start the drive motor 303, the drive motor 303 drives the rotating shaft 301 to rotate through the gearbox 302, the gearbox 302 can change the speed of the drive motor 303, so that it can adapt to different situations, the rotation of the rotating shaft 301 drives the hinge plate 304 to rotate, and a hinge 504 is fixed at one end of the hinge plate 304. When the hinge plate 304 rotates, the hinge 504 can be pulled, and the groove plate 306 can limit the door panel 503 so that the door panel 503 can be rolled into the shell 1. The drive motors 303 on the left and right sides can be started at the same time through the controller 2, or a single drive motor 303 can be started to drive the door panel 503 on one side to pull the rolling curtain. When the drive motors 303 on both sides are started at the same time, the hinge 504 drives the door panel 503 To roll up the shutter, the sliding block 502 will slide in the sliding groove 501, and the sliding groove 501 will limit the sliding block 502. The hinge 504 can also drive the limit block 506 and the clamping plate 507 to roll up the shutter, so that all the door panels 503 can be rolled up into the shell 1. When only one side of the driving motor 303 is started, the hinge 504 drives the door panel 503 on one side to roll up the shutter, and the clamping plate 507 will be pressed by the base 505 and will not move, so that the door panel 503 on one side can be rolled up. At this time, the limit block 506 will slide in the clamping plate 507, and the clamping plate 507 will limit the limit block 506, acting as a guide rail 4, and will not affect the use of the rolling door. In this way, even if one side of the door panel 503 is damaged, rescue time will not be wasted, thereby improving the safety performance of the rolling door.
