Description

Technical Field

[0001] The utility model relates to a central support bracket for splicing rolling curtains. Background Art

[0002] The double-jointed roller blind is a specially designed curtain type suitable for large-span windows or door openings. By splicing two or more roller blind fabrics together, it can achieve large-area shading, heat insulation, privacy protection and other functions. The double-jointed roller blind connects and stabilizes two or more roller blind fabrics through the cooperation of the spline sleeve and the spline sleeve tail, ensuring that they remain synchronized, flat and stable during the process of unfolding, folding and operation. In order to make the connection more stable, the spline sleeve and the spline sleeve tail are usually fixed and supported by a central bracket.

[0003] However, the existing center brackets are either top mounted or side mounted, which cannot be adapted to all situations, so the applicant has made improvements. Utility Model Content

[0027] (Example 1)

[0028] See Figure 1-2 A central support for a spliced ​​roller shutter comprises a mounting frame 1 and a bearing adjustment frame 2. The mounting frame 1 is provided with a top mounting plate 1-1 and a side mounting plate 1-2. The bearing adjustment frame 2 comprises a bearing fixing frame 2-1 and a direction adjustment plate 2-2. The direction adjustment plate 2-2 is detachably fixed to the mounting frame 1. A through hole for the bearing fixing frame 2-1 to move is provided in the middle of the direction adjustment plate 2-2. The bearing fixing frame 2-1 is slidably connected with the direction adjustment plate 2-2 within the range of the through hole. The direction of the direction adjustment plate 2-2 is adjustable so that the moving direction of the bearing fixing frame 2-1 is changed between a first direction and a second direction. The first direction is parallel to the top mounting plate 1-1, and the second direction is parallel to the side mounting plate 1-2.

[0029] Specifically, the mounting frame 1 and the direction adjustment plate 2-2 are provided with matching adjustment screw holes, and the direction adjustment plate 2-2 is fixedly connected to the mounting frame 1 by screws, and there are four adjustment screw holes, which are distributed in a square. When the installation scheme is switched between top mounting and side mounting, it is only necessary to remove the screws, rotate the direction adjustment plate 2-2 90°, and then fix it with screws.

[0030] A sliding column 2-2-1 and an adjusting bolt 2-2-2 are arranged in the through hole of the direction adjustment plate 2-2. The sliding column 2-2-1 and the adjusting bolt 2-2-2 are parallel. The sliding column 2-2-1 is fixed in the through hole. The adjusting bolt 2-2-2 is rotatably connected with the direction adjustment plate 2-2. One end of the bearing fixing frame 2-1 is sleeved on the sliding column 2-2-1 and slides axially along the sliding column 2-2-1. The other end of the bearing fixing frame 2-1 is threadedly connected with the adjusting bolt 2-2-2. The distance between the bearing fixing frame and the top mounting plate, or between the fixing frame and the side mounting plate, can be changed by rotating the adjusting bolt.

[0031] Both the top mounting plate 1-1 and the side mounting plate 1-2 are provided with mounting screw holes 1-3, and the mounting screw holes 1-3 are waist-shaped holes, which are convenient for later installation.

[0032] A bearing 3 is arranged in the middle of the bearing fixing frame 2-1, the outer ring of the bearing 3 is fixed to the bearing fixing frame 2-1, and the inner ring of the bearing 3 cooperates with the spline sleeve tail installed at the end of the rolling curtain, so that the spline sleeve tail can rotate on the entire central bracket.

[0033] A hook 1-4 extends outward from one end of the top mounting plate 1-1 away from the side mounting plate 1-2. The hook 1-4 is used to hang the outer cover plate of the curtain, making the curtain more beautiful as a whole. In the prior art, whether it is a top-mounted or side-mounted central bracket, the installation method can actually be changed after the whole is rotated 90°. However, such a central bracket cannot be designed with a hook for hanging the cover plate. Once the installation method is changed, the direction of the hook will also change, and the cover plate cannot be hung. Therefore, there is no hook designed on the traditional central bracket, and the entire central device will be exposed to the outside, affecting the appearance. In this embodiment, since it is the direction adjustment plate 2-2 that is rotated, the overall direction of the mounting frame 1 remains unchanged, and the effect is better.

[0034] The mounting frame 1 of the center bracket of the utility model is provided with a top mounting plate 1-1 and a side mounting plate 1-2, which can adapt to various installation environments. At the same time, because the orientation of the direction adjustment plate 2-2 can be adjusted, the movable direction of the bearing fixing frame 2-1 can be changed between the first direction and the second direction. When the top mounting solution is adopted, the bearing fixing frame 2-1 is adjusted to slide along the second direction. When the side mounting solution is adopted, the bearing fixing frame 2-1 is adjusted to slide along the first direction, so that the center bracket can better support the end of the roller blind.

[0035] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
