Description

Technical Field

[0001] This utility model relates to the field of roller blinds, and more specifically, it relates to an easy-to-install roller blind bottom beam. Background Technology

[0002] Traditional roller blind bottom beams mostly use a one-piece structure, requiring the curtain end to be inserted into the fixing groove of the bottom beam during installation. This process is cumbersome and can easily lead to wrinkles or damage to the curtain material. Although some detachable bottom beams are separated using a snap-fit ​​structure, they still suffer from insufficient clamping force and poor stability after installation.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-to-install roller shutter bottom beam.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an easy-to-install roller blind bottom beam includes a detachably connected outer frame and a curtain material clamping assembly. The curtain material clamping assembly includes a first clamping block, a second clamping block, and a third clamping block arranged in sequence. The first clamping block, the second clamping block, and the third clamping block can be separated and combined with each other. The side of the first clamping block facing the second clamping block has a wavy surface, and the second clamping block also has a corresponding wavy surface. The side of the second clamping block facing the third clamping block has a protruding strip, and the side of the third clamping block facing the second clamping block has a groove that matches the protruding strip. When the outer frame and the curtain material clamping assembly are connected, the outer frame can keep the first clamping block, the second clamping block, and the third clamping block in a combined state.

[0006] The present invention is further configured such that: the cross-sectional shape of the outer frame is U-shaped, and elastic clips are provided on the left inner sidewall and the right inner sidewall of the outer frame; a slot matching the elastic clip is provided on the side of the first clamping block away from the second clamping block; and a slot matching the elastic clip is provided on the side of the third clamping block away from the second clamping block.

[0007] The present invention is further configured such that: the elastic clip includes an upper clip and a lower clip, the upper clip located on the left inner side wall and the right inner side wall of the outer frame are at corresponding heights, and the lower clip located on the left inner side wall and the right inner side wall of the outer frame are at corresponding heights.

[0008] The present invention is further configured such that: the bottom ends of the first clamping block and the third clamping block are provided with guide slopes, so that the combined first clamping block, second clamping block and third clamping block form a structure that is narrow at the bottom and wide at the top.

[0009] In summary, this utility model has the following beneficial effects:

[0010] This utility model features a detachably connected outer frame and curtain material clamping assembly. The clamping blocks are designed to be disassembled without tools, making it easy to replace the curtain material or adjust the clamping position. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: An easy-to-install roller shutter bottom beam, such as Figure 1 , 2 As shown, the device includes a detachably connected outer frame 1 and a curtain material clamping assembly. The outer frame 1 is made of aluminum profile. The curtain material clamping assembly consists of a first clamping block 2, a second clamping block 3, and a third clamping block 4 arranged sequentially. These three components can be separated or combined. The contact surfaces of the first clamping block 2 and the second clamping block 3 are provided with a wavy meshing surface, which increases friction through the interlocking of concave and convex surfaces to prevent slippage between the clamping blocks. The second clamping block 3 and the third clamping block 4 are precisely positioned by a convex strip 6-groove 7 structure to ensure alignment of the curtain material clamping assembly.

[0016] The outer frame 1 has a U-shaped cross-section. When the curtain clamping assembly is located inside the outer frame 1, the outer frame 1 can keep the curtain clamping assembly in an assembled state. Elastic clips 8 are provided on the left inner sidewall and the right inner sidewall of the outer frame 1. The first clamping block 2 has a slot 9 that matches the elastic clip 8 on the side away from the second clamping block 3. The third clamping block 4 has a slot 9 that matches the elastic clip 8 on the side away from the second clamping block 3.

[0017] The elastic clip 8 includes an upper clip and a lower clip. The upper clip located on the left inner side wall and the right inner side wall of the outer frame 1 have corresponding heights, and the lower clip located on the left inner side wall and the right inner side wall of the outer frame 1 have corresponding heights.

[0018] The bottom ends of the first clamping block 2 and the third clamping block 4 are provided with guide slopes 10, so that the combined first clamping block 2, second clamping block 3 and third clamping block 4 form a structure that is narrow at the bottom and wide at the top, forming a wedge-shaped structure that is narrow at the bottom and wide at the top, which facilitates automatic alignment and locking when the outer frame 1 is inserted.

[0019] Taking PVC curtain installation as an example:

[0020] Pre-fixing of the curtain material: Lay the end of the curtain material flat between the second clamping block 3 and the third clamping block 4, align the groove 7 of the third clamping block 4 with the protrusion 6 of the second clamping block 3, and push it in vertically until it is completely fitted. Then lay the remaining part of the curtain material flat on the wavy surface 5 between the second clamping block 3 and the first clamping block 2, and press it to make the two initially mesh.

[0021] Clamping block assembly:

[0022] Outer frame 1 assembly: Push the assembled clamping assembly upward from the bottom of the outer frame 1. The guide slope 10 guides the clamping block to the center. The elastic clips 8 (upper and lower clips) of the outer frame 1 are simultaneously inserted into the slots 9 of the first clamping block 2 and the third clamping block 4. A "click" sound indicates that the installation is complete.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
