[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1 , 34. A noise reduction rolling shutter door, comprising a rolling shutter door 1, two fixing mechanisms symmetrically fixed on the door frame of the rolling shutter door 1, two fixing mechanisms are fixed with fixing plates 2, the positions of the two fixing plates 2 are restricted on the door frame of the rolling shutter door 1 by the two fixing mechanisms, two connecting plates 12 are fixed between the two fixing plates 2, an electric telescopic rod 5 is fixed on each connecting plate 12, an extrusion plate 10 is fixed on the electric telescopic rod 5, a protective pad 11 is fixed on the extrusion plate 10, the protective pad 11 is in contact with the door curtain of the rolling shutter door 1, and a protective pad 11 is fixed on the extrusion plate 10 between the two connecting plates 12 and the door frame of the rolling shutter door 1. After the distance between them is determined, the distance between the two extrusion plates 10 and the door frame of the rolling door 1 can be adjusted by extending the two electric telescopic rods 5 at the same time until the two extrusion plates 10 are pressed on the door curtain of the rolling door 1, so that the door curtain of the rolling door 1 is pressed tightly, and when the wind blows the rolling door 1, the door curtain of the rolling door 1 will not make a rustling sound. In addition, the protective pad 11 is separated between the extrusion plates 10 and the door curtain of the rolling door 1, which not only protects the surface of the door curtain of the rolling door 1 from being scratched by the extrusion plates 10, but also prevents noise from friction when the extrusion plates 10 squeeze the door curtain of the rolling door 1.

[0021] When the noise reduction rolling door is in use, two fixing mechanisms are used to fix the two fixing plates 2 on the door frame of the rolling door 1, and the two electric telescopic rods 5 are started to allow the two squeezing plates 10 to squeeze the door curtain falling from the rolling door 1, so that the door curtain of the rolling door 1 can be restricted and the door curtain of the rolling door 1 will not shake when blown by the wind. Therefore, it will not make a rustling sound when blown by the wind, and will not affect people resting in the house. In addition, the two squeezing plates 10 squeeze the door curtain falling from the rolling door 1, which can also provide a safety guarantee for the rolling door 1.

[0022] Example 2

[0023] Based on Example 1, Figure 1 , 2 , 4 and 5, as another preferred embodiment of the utility model, the difference from embodiment 1 is that the fixing mechanism includes two fixing rods 3, the two fixing rods 3 are symmetrically fixed on the fixing plate 2, the two fixing rods 3 are fixed with electromagnets 4, the electromagnets 4 are in contact with the door frame of the rolling door 1, and when the electromagnets 4 are energized, the electromagnets 4 are adsorbed and fixed on the door frame of the rolling door 1, and the two fixing plates 2 are fixed on the door frame of the rolling door 1 by magnetic attraction;

[0024] An automatic control mechanism is fixed on each fixed plate 2, and the automatic control mechanism is electrically connected to a plurality of electromagnets 4. When the automatic control mechanism is used to allow the plurality of electromagnets 4 to contact the door frame of the rolling door 1, they will be energized, and workers do not need to control it separately, freeing their hands. The automatic control mechanism includes a spring 7, one end of the spring 7 is fixed on the fixed plate 2, and the other end is fixed to a touch switch 6, and the touch switch 6 is electrically connected to the plurality of electromagnets 4. When the plurality of electromagnets 4 contact the door frame of the rolling door 1, the touch switch 6 is also squeezed on the door frame of the rolling door 1. At this time, the touch switch 6 is used to automatically connect the power supply to the circuit that supplies power to the plurality of electromagnets 4, so that the plurality of electromagnets 4 can be adsorbed and fixed on the door frame of the rolling door 1.

[0025] A cylinder 8 and an insertion rod 9 are inserted in the spring 7. The cylinder 8 is fixed on the fixed plate 2. One end of the insertion rod 9 is inserted in the cylinder 8 and the other end is fixed on the touch switch 6. The support of the cylinder 8 and the insertion rod 9 does not affect the compression and rebound of the spring 7, and can also ensure that the spring 7 will not bend, so that the touch switch 6 can maintain linear movement.

[0026] When in use, hold the connecting plate 12 and press the connecting plate 12 to move the multiple electromagnets 4 toward the door frame of the rolling door 1. At this time, the touch switch 6 has been in contact with the door frame of the rolling door 1. When the connecting plate 12 continues to approach the door frame of the rolling door 1, the spring 7 is compressed and the insertion rod 9 is inserted into the cylinder 8. When the two fixing plates 2 are in contact with the door frame of the rolling door 1, the touch switch 6 is pressed by the door frame of the rolling door 1 to control the multiple electromagnets 4 to be energized, thereby allowing the multiple electromagnets 4 to be adsorbed and fixed on the door frame of the rolling door 1.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
