[0029] In the description of the present invention, “plurality” means two or more, unless otherwise clearly defined.

[0030] Example 1:

[0031] Please refer to Figures 1-6 A silent head structure for a rolling shutter door includes a head body 1 and a plurality of silent cottons 2.

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, the head body 1 includes a vertical portion 12 and a horizontal portion 11. The vertical portion 12 and the horizontal portion 11 are arranged perpendicular to each other to form an L-shaped structure. When the head body 1 is installed on the rolling door, the vertical portion 12 is against the side wall of the rolling door, and the horizontal portion 11 is against the front of the rolling door.

[0033] Several silent cottons 2 are detachably connected to the horizontal part 11. With such arrangement, when several rolling shutter doors are rolled up, the rolling shutter doors abut against the silent cotton 2, thereby avoiding contact between the rolling shutter doors and the head body 1, effectively reducing noise; the silent cotton 2 collides with the rolling shutter doors for a long time, causing the silent cotton 2 to wear and reduce the sound-absorbing effect. Therefore, by detachably arranging the silent cotton 2 and the horizontal part 11, the worn silent cotton 2 can be removed and replaced with a new silent cotton 2 to meet the sound-absorbing requirements.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, the horizontal part 11 has several mounting grooves 11a, and the bottom of the silent cotton 2 has a protrusion 21 with the same shape as the mounting groove 11a. The protrusion 21 can be embedded in the mounting groove 11a, thereby realizing the connection between the silent cotton 2 and the horizontal part 11; both ends of the mounting groove 11a pass through the horizontal part 11, and the silent cotton 2 is separated from the mounting groove 11a by sliding the silent cotton 2 to both sides, completing the disassembly.

[0035] The vertical portion 12 has a mounting hole 12a, through which a screw passes to connect the head body 1 to the rolling door. The head body 1 can be installed on or removed from the rolling door by tightening or loosening the screw.

[0036] like Figure 1 、 Figure 3 and Figure 4 As shown, the two ends of the vertical portion 12 are respectively provided with a first connecting plate 121 and a second connecting plate 122; when several head bodies 1 are respectively installed on the rolling shutter door, the outer wall of the first connecting plate 121 abuts against the inner wall of the second connecting plate 122, as shown in FIG. Figure 5 and Figure 6 As shown; the outer wall of the first connecting plate 121 of the upper head body 1 is abutted against the inner wall of the second connecting plate 122 of the lower head body 1, so that several head bodies 1 limit the horizontal direction of the lower head body 1 and the rolling door in turn, and no sliding will occur between several adjacent rolling doors, so that the two ends of several rolling doors are always located in the same straight line, ensuring the normal use of the rolling doors.

[0037] The working principle of this embodiment is:

[0038] When the rolling shutter door is rolled up, the rolling shutter door abuts against the silent cotton 2, thereby preventing the rolling shutter door from contacting the head body 1, effectively reducing noise; the silent cotton 2 collides with the rolling shutter door for a long time, causing the silent cotton 2 to wear and reduce the sound-absorbing effect. Therefore, by making the silent cotton 2 and the horizontal part 11 detachable, the worn silent cotton 2 can be removed and replaced with a new silent cotton 2 to meet the sound-absorbing requirements.

[0039] Example 2:

[0040] This embodiment is an improvement based on embodiment 1. When several head bodies 1 are installed on the rolling door, due to the abutment between the first connecting plate 121 and the second connecting plate 122, friction is generated when the first connecting plate 121 and the second connecting plate 122 rotate. Depending on the surface roughness, noise may be emitted; or when the connecting shaft of the rolling door is rusted, a sharp and harsh sound may be emitted during rotation.

[0041] Please refer to Figure 7 , and also includes a rotating member 3, which includes a rotating shaft 31, two rotating plates 32 and a plurality of spheres 33; the two rotating plates 32 are respectively sleeved on both ends of the rotating shaft 31, and the inner walls of the rotating plates 32 and the outer periphery of the rotating shaft 31 respectively have arc-shaped grooves, and the plurality of spheres 33 are respectively embedded between the rotating plates 32 and the rotating shaft 31 and embedded in the arc-shaped grooves, so that the rotating plates 32 and the rotating shaft 31 are rotatably connected.

[0042] The first connecting plate 121 and the second connecting plate 122 each have a through hole. When the rotating member 3 connects the two head bodies 1, the two rotating plates 32 are respectively embedded in the through holes of the first connecting plate 121 and the second connecting plate 122. Due to the presence of the plurality of spheres 33, there is rolling friction between the rotating plate 32 and the rotating shaft 31, which greatly reduces the friction between the rotating plate 32 and the rotating shaft 31 and also reduces the noise generated by the rotation. At the same time, any two adjacent head bodies 1 are connected by the rotating member 3, which can eliminate the connecting shaft between the two adjacent rolling shutters, thereby avoiding the rust of the connecting shaft causing the rolling shutter to rotate and emit a sharp and harsh sound. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
