[0029] Reference Figure 1 and Figure 2 The utility model provides a shaft support bracket structure, including a bracket body 1 and a supporting unit 2. The number of the bracket bodies 1 is several, and the several bracket bodies 1 are connected to the keel structure of the rolling shutter box 5 at intervals. The bracket body 1 is provided with a storage groove 11 for the rolling shutter main shaft 4 and the rolling shutter to pass through. The supporting unit 2 is connected to the bracket body 1 and is located at the middle and lower edge of the storage groove 11, and the supporting unit 2 can contact the rolling shutter.

[0030] During daily use, the supporting unit 2 can support the roller blind and the roller blind main shaft 4, and through the arrangement of a certain number of bracket bodies 1, multiple supports can be formed along the length direction, thereby effectively reducing the deflection of the roller blind main shaft 4 as a whole, further reducing deformation, ensuring the use effect, and extending the service life.

[0031] As an optional implementation, a plurality of support bodies 1 are evenly distributed at equal intervals. Such an arrangement can balance the force, make the force more uniform, and improve the supporting effect.

[0032] As an optional implementation, the bracket body 1 is connected to the rolling shutter box 5 by welding. The welding connection has good connection strength, which can extend the service life of the bracket body 1 and reduce the risks during use.

[0033] As an optional embodiment, the supporting unit 2 includes a plurality of rolling wheels 21, which are detachably connected to the bracket body 1. The rolling wheels 21 can rotate relative to the bracket body 1 after being subjected to force, so that the rolling curtain and the rolling curtain main shaft 4 can be supported during the movement of the rolling curtain. By setting a certain number of rolling wheels 21, multiple supports can be formed along the circumferential direction, thereby reducing the deflection of the rolling curtain main shaft 4 and reducing deformation in general.

[0034] The middle and upper part of the rolling wheel 21 is located inside the storage groove 11 , so it can be relatively extended to a certain distance, which is more conducive to contact with the rolling curtain and also conducive to supporting the rolling curtain and the rolling curtain main shaft 4 .

[0035] As an optional implementation, the bracket body 1 is provided with a bolt hole at the corresponding connection position of each rolling wheel 21, and the rolling wheel 21 is bolted to the bolt hole through a fixing bolt. The bolt connection has good connection strength and is easy to disassemble and assemble, and is convenient for replacement and maintenance.

[0036] As an optional embodiment, rolling wheels 21 are connected to both sides of the bracket body 1. Such an arrangement can balance the force on both sides of the bracket body 1, so that the roller blind and the roller blind main shaft 4 are more evenly stressed on both sides of the bracket body 1, forming a better supporting effect and reducing deformation;

[0037] In this embodiment, for the sake of convenience, the drawings do not show the schematic effect of having rolling wheels 21 on both sides, but only show the schematic effect of having rolling wheels 21 on one side.

[0038] As an optional implementation, it also includes a guide limit unit 3, which is connected to the bracket body 1 and located at the top of the exit of the rolling curtain. The guide limit unit 3 can form a guide limit effect on the rolling curtain, making the rolling curtain more stable when lifting.

[0039] As an optional embodiment, the guide limiting unit 3 includes a guide wheel 31, which is detachably connected to the bracket body 1. The guide wheel 31 can rotate relative to the bracket body 1 after being subjected to force, so that during the movement of the rolling curtain, the rolling curtain and the rolling curtain main shaft 4 can be guided and limited, which is more stable;

[0040] The bottom of the guide wheel 31 is located inside the storage groove 11, so it can be relatively extended to a certain distance, which is more conducive to contact with the rolling curtain.

[0041] As an optional implementation, the bracket body 1 is provided with a bolt hole at the corresponding connection position of the guide wheel 31, and the guide wheel 31 is bolted to the bolt hole through a fixing bolt. The bolt connection has good connection strength and is easy to disassemble and assemble, and is convenient for replacement and maintenance.

[0042] As an optional embodiment, guide wheels 31 are connected to both sides of the bracket body 1. Such a configuration can balance the force on both sides of the bracket body 1, so that the roller blind and the roller blind main shaft 4 are more evenly stressed on both sides of the bracket body 1, thereby forming a better guiding effect.

[0043] In this embodiment, for the sake of convenience, the schematic effect of having guide wheels 31 on both sides is not shown in the drawings, but only the schematic effect of having guide wheels 31 on one side is shown.

[0044] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
