[0002] Roller shutters (also known as roller blinds) are doors with multiple articulated door panels linked together, rotating up and down around a central roller within fixed tracks. They are commonly used in shops. Roller shutters primarily function by using a built-in motor drive, chain drive, limit switch control, and other control systems to automatically open and close the door and retract the shutter.

[0025] Example 1

[0026] Please see Figure 1-6The present invention provides an embodiment of a silent fireproof roller shutter door, comprising: a first door frame 2 and a second door frame 4, which are installed on both sides of a building door; a support plate 7, which is located at the top of the same end of the first door frame 2 and the second door frame 4; a roller shutter door rewind box 1 is provided at the top of the first door frame 2 and the second door frame 4; a roller shutter door body 3 is provided inside the roller shutter door rewind box 1; and a structure for rewinding the roller shutter door body 3 is provided inside the roller shutter door rewind box 1. This structure is an existing structure and will not be described in detail here. Furthermore, the roller shutter door body 3 slides inside the door frame 2 and door frame 4 on both sides. Sound-absorbing foam 16 is installed on the inner walls of the roller shutter door retractor box 1, door frame 2, and door frame 4. A sound-absorbing plate 19 is installed on the inner wall of door frame 4. A sound-absorbing hole 18 is provided on the outer wall of the sound-absorbing plate 19, and a sound-absorbing hole 17 is provided on the inner wall of the sound-absorbing plate 19. The sound-absorbing holes 17 and 18 are staggered. Fire-retardant material is applied to the surfaces of the roller shutter door retractor box 1, door frame 2, roller shutter door body 3, and door frame 4 to provide a certain fire-resistant effect. The sound-absorbing holes 17 and 18 are hexagonal and partially connected. In the rolling and unfolding states of the roller shutter door 3, the two sides of the roller shutter door 3 move along the interior of the door frame 1 2 and the door frame 2 4. However, noise is generated during the movement. The noise flows along the sound-absorbing holes 17 and 18. However, during the movement, the noise is reduced to a certain extent. Then, the sound-absorbing foam 16 further reduces the noise. Through the dual noise reduction effects, a silent state is achieved.

[0027] Example 2

[0028] Please see Figure 1-6 A silent fireproof roller shutter door has two bolt plates 14 fixed at both ends of the bottom of the roller shutter door's retractor box 1. A bolt hole 8 is vertically opened on the support plate 7 for the bolt plates 14 to be inserted. A bolt hole 9 is horizontally opened inside the support plate 7, and the bolt hole 9 passes through the bolt hole 28. A bolt hole 6 is horizontally opened inside the auxiliary handle 5, and a bolt plate 11 is inserted into the bolt hole 9, passing through both the bolt hole 9 and the bolt hole 6. A fixing plate 10 is provided on the lower surface of the support plate 7, and a vertical plate 13 is provided at one end of the bolt plate 11. A tension spring 12 is provided between the vertical plate 13 and the fixing plate 10, and the tension spring 12 is in a retracted state. A rotating plate 15 is rotatably mounted on the lower surface of the support plate 7 above the tension spring 12, and a horizontal notch is provided on the vertical plate 13 for the rotating plate 15 to be inserted.

[0029] After the roller shutter rewind box 1 is placed on the door frame 1 2 and the door frame 2 4, the latch plate 2 14 is inserted into the support plate 7 through the latch hole 2 8. The support plate 7 provides support for the roller shutter rewind box 1. Before the latch plate 2 14 is inserted into the latch hole 2 8, the rotating plate 15 rotates, and one side of the rotating plate 15 abuts against the notch on the vertical plate 13. At this time, the latch plate 1 11 is away from the latch hole 2 8, and the tension spring 12 is in the unfolded state. After the latch plate 2 14 is inserted into the latch hole 2 8, the rotating plate 15 is rotated again. The rotating plate 15 does not abut against the vertical plate 13. At this time, the vertical plate 13, under the tension of the tension spring 12, causes the latch plate 1 11 to pass through the support plate 7 and into the latch plate 2 14. In this way, the roller shutter rewind box 1 is firmly assembled on the roller shutter rewind box 1, and it is also easy to disassemble later. The above description shows that the second pin plate 14 and the support plate 7 are vertically connected, while the first pin plate 11 and the second pin plate 14 are horizontally connected. This improves the stability of the roller shutter door rewind box 1 assembled on the first door frame 2 and the second door frame 4.

[0030] An auxiliary handle 5 is located at the bottom of one end of the roller shutter door body 3, with one end of the auxiliary handle 5 away from the surface of the roller shutter door body 3. An L-plate 20 is provided at one end of the roller shutter door body 3 near the bottom. A second magnet 22 is provided on the upper surface of the auxiliary handle 5, and a first magnet 21 is provided at the top of the inner wall of the L-plate 20. The first magnet 21 and the second magnet 22 are connected by adsorption. By using an adsorption connection, the auxiliary handle 5 can be placed on one side of the roller shutter door body 3 without affecting the bottom of the roller shutter door body 3 contacting the ground. However, before the roller shutter door body 3 is rolled up, the person holds one side of the auxiliary handle 5 and lifts the roller shutter door body 3. Then, the existing winding device in the roller shutter door winding box 1 is used to wind up the roller shutter door body 3. When the roller shutter door body 3 has been raised to a certain height, the auxiliary handle 5 is pulled down to make the auxiliary handle 5 vertical. This makes it easy to pull the roller shutter door body 3 down with the auxiliary handle 5 before closing the door, so that people of shorter stature do not have to be unable to pull the roller shutter door body 3 down.

[0031] Working principle: During use, the roller shutter door body 3 is first wound up within the roller shutter door rewind box 1 according to the original structure of the roller shutter door. However, during the winding process, the two sides of the roller shutter door body 3 move inside the door frame 1 2 and door frame 2 4, which will generate noise in a certain process. At this time, the noise enters the noise reduction hole 18 along the noise reduction hole 17. The noise reduction hole 17 and the noise reduction hole 2 18 are staggered and utilize multiple small noise reduction channels of resistive silencers. The noise will be weakened as it flows along the noise reduction hole 17 and the noise reduction hole 2 18. Then, the noise will be further weakened by the action of the sound-absorbing foam 16, thus forming a silent state.

[0032] Secondly, when the roller shutter door is pulled down to open and close, since the auxiliary handle 5 is in a vertical position, the operator can simply pull the auxiliary handle 5. When the auxiliary handle 5 is pulled to the appropriate position, it is rotated to rest on the L-plate 20 using magnets 22 and 21. When the roller shutter door 3 is retracted, the operator pulls the auxiliary handle 5 down to make it vertical, and at this time, the auxiliary handle 5 is positioned close to the door frame 4. Finally, the use of the silent fireproof roller shutter door is completed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
