[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a fireproof rolling shutter door that is easy to install provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the lifting plate installation structure is shown; Figure 3 for Figure 1The schematic diagram of the sliding sleeve installation structure is shown, a fire shutter door that is easy to install, comprising: two bases 1, the tops of the two bases 1 are both rotatably installed with screw rods 2 through bearings, a top plate 3 is provided between the tops of the two screw rods 2, the two screw rods 2 and the top plate 3 are rotatably installed through bearings, the tops of the two screw rods 2 both penetrate the top plate 3 and are key-connected with a first gear 4, the outsides of the two first gears 4 are both meshedly connected with a second gear 5, the center points of the two second gears 5 are key-connected with a motor 6, the two motors 6 are both fixedly installed with the top plate 3, a lifting plate 7 is meshedly connected between the two screw rods 2, and a lifting plate 7 is provided between the two screw rods 2. The plate 7 moves up and down along the length direction of the screw rod 2 through the rotation of the screw rod 2. A protective shell 8 is fixedly installed on the top of the lifting plate 7. Since the heights of doors of different buildings are different, it is necessary to customize the rolling door according to the actual height when installing it, and the customization cost is relatively high. The motor 6 effectively drives the second gear 5 to rotate, the second gear 5 drives the first gear 4 to rotate, and the first gear 4 drives the screw rod 2 to rotate. The rotation of the two screw rods 2 effectively changes the height of the lifting plate 7, which is convenient for adjustment according to the actual height, greatly improving the practicability of the rolling door and facilitating installation.

[0020] Slide rails 9 are fixedly installed on the top of the two bases 1 and on the outer side of the screw rod 2. The tops of the two slide rails 9 are fixedly installed between the top plate 3. The fixed installation of the slide rails 9 and the top plate 3 greatly improves the stability of the rolling door.

[0021] A rolling door 10 is provided inside the protective shell 8, and the outer sides of the rolling door 10 are located inside the two sliding rails 9. A handle 11 is fixedly installed on the outer side of the rolling door 10. A rolling mechanism is provided inside the protective shell 8. The rolling shutter door is an existing mature technical means and will not be introduced in detail here. The sliding rails 9 are used to effectively limit the rolling door 10 to prevent the rolling door 10 from deflecting, thereby greatly improving the stability.

[0022] A mounting plate 12 is welded to one side of the top of the top plate 3, and the mounting plate 12 is effectively fixed to the wall by screws.

[0023] A sliding rod 14 is welded to one side of the outside of one of the bases 1, and a sliding sleeve 13 is welded to one side of the outside of the other base 1. The sliding rod 14 is slidably installed with the sliding sleeve 13 along the length direction of the sliding sleeve 13. A bolt 15 is threadedly connected to the top of the sliding sleeve 13, and the number of bolts 15 is two. The sliding rod 14 is fixed to the sliding sleeve 13 by locking bolts 15. Since the widths of doors of different buildings are different, the sliding rod 14 can slide inside the sliding sleeve 13 by loosening the bolts 15, which is convenient for adjusting to a suitable position according to the width of the door. After the adjustment, the bolts 15 are locked, and then the appropriate protective shell 8 and the rolling door 10 are rotated according to the width for installation. This structure is simple and easy to install, which greatly improves the installation efficiency.

[0024] The working principle of the fireproof rolling shutter door which is easy to install provided by the utility model is as follows:

[0025] Step 1: Since the widths of doors of different buildings are different, by loosening the bolts 15, the slide rod 14 can slide inside the slide sleeve 13, which is convenient for adjusting to a suitable position according to the width of the door. After the adjustment, the bolts 15 are tightened, and then the appropriate protective shell 8 and the rolling door 10 are rotated according to the width for installation. Since the heights of doors of different buildings are different, it is necessary to customize the rolling door according to the actual height when installing it, and the customization cost is relatively high. The motor 6 effectively drives the second gear 5 to rotate, and the second gear 5 drives the first gear 4 to rotate, and the first gear 4 drives the screw rod 2 to rotate. The rotation of the two screw rods 2 effectively changes the height of the lifting plate 7, which is convenient for adjustment according to the actual height, greatly improving the practicality of the rolling door and facilitating installation.

[0026] Step 2: The fixed installation of the slide rail 9 and the top plate 3 greatly improves the stability of the rolling door. A winding mechanism is provided inside the protective shell 8. The rolling door is an existing mature technical means and will not be introduced in detail here. The slide rail 9 effectively limits the rolling door 10 to avoid deviation of the rolling door 10, thereby greatly improving the stability.

[0027] Compared with the related art, the fireproof rolling shutter door provided by the utility model which is easy to install has the following beneficial effects:

[0028] Since the heights of doors of different buildings are different, the rolling door needs to be customized according to the actual height when it is installed, and the customization cost is relatively high. The motor 6 effectively drives the second gear 5 to rotate, the second gear 5 drives the first gear 4 to rotate, and the first gear 4 drives the screw rod 2 to rotate. The rotation of the two screw rods 2 effectively changes the height of the lifting plate 7, which is convenient for adjustment according to the actual height, greatly improving the practicality of the rolling door and facilitating installation.
