[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-4 The utility model provides an embodiment of a fire truck rolling door structure, including a guide rail 1, a door panel 9 is arranged on the inner side of the guide rail 1, and the door panel 9 can have its normal retracting and releasing function by arranging the guide rail 9. The two ends of the bottom of the guide rail 1 are fixedly connected with a fixing seat 3, and the two ends of the bottom of the door panel 9 are rotatably connected with a rotating frame 2, and the other end of the rotating frame 2 is rotatably connected with a rotating member 6, and the door head rod 7 can be driven to move by the rotating frame 2 and the rotating member 6;

[0026] The rotating member 6 is fixedly connected to the door head rod 7 inside, and the two ends of the door head rod 7 are fixedly connected to the limiting block 5. The fixed seat 3 is provided with a limiting groove 8, and the limiting block 5 corresponds to the limiting groove 8. The limiting block 5 is provided with a groove 14 inside, and the inside of the groove 14 is fixedly connected to the fixing plate 12. The two ends of the fixing plate 12 are fixedly connected to the first spring 13, and the other end of the first spring 13 is fixedly connected to the limiting plate 11. The other end of the limiting plate 11 is fixedly connected to the positioning block 10. The two ends of the fixing seat 3 are penetrated with the positioning groove 4, and the positioning block 10 and the positioning groove 4, during the process of pulling down, the limit blocks 5 at both ends can correspond to the limit grooves 8 inside the fixing seat 3, and the positioning blocks 10 at both ends are pressed inward to shrink inward, at this time, the limit blocks 5 can stably enter the inside of the limit grooves 8, and after the positioning blocks 10 at both ends of the limit block 5 pass the position of the positioning grooves 4, the first springs 13 inside can make the limit plates 11 drive the positioning blocks 10 to pop outward, so that the positioning blocks 10 are clamped and fixed with the positioning grooves 4, so that the staff can play a role of insurance when closing the door head rod 7;

[0027] The rotating end of the rotating frame 2 connected to the rotating member 6 is fixedly connected with a second gear 19, and an outer end of the rotating member 6 is fixedly connected with a mounting plate 17. The second gear 19 is connected to the rotating shaft of the rotating frame 2, so that the rotating frame 2 can drive the second gear 19 to rotate during the rotation process;

[0028] A movable rod 16 is movably connected to the mounting plate 17, and a second spring 15 is arranged on the movable rod 16. A first gear 18 is fixedly connected to the inner end of the movable rod 16, and the first gear 18 and the second gear 19 are meshed with each other. When the door head rod 7 is pulled down, the staff needs to pull the movable rod 16 outwards, and the first gear 18 can be driven to disengage from the second gear 19 under the action of the movable rod 16 to ensure the stable rotation of the rotating frame 2.
