Description

Technical Field

[0001] The utility model relates to a curtain lower beam system. Background Art

[0002] With the development of society, people's requirements for curtain products are not only functional, but also have higher and higher aesthetic requirements for their appearance. From the initial requirement of only blocking light to meet the normal retraction and release functions, to requiring the curtain cover and lower beam and other profiles and fabrics to be color-matched in order to make the curtain look more beautiful. For example, the patent with application number 2023210158891 is provided with a wrapping cloth on the outer surface of the U-shaped lower beam to make the surface color of the lower beam consistent with the main color of the curtain, thereby improving the overall look of the curtain. The coordination between the lower beam head and the round lower beam requires the addition of a round lower beam head, which is also the mainstream setting method in the industry. However, this setting method not only increases the manufacturing cost due to the addition of a round lower beam head, but also adds processes to the later assembly. Therefore, the applicant has made improvements to this. Utility Model Content

[0025] (Example 1)

[0026] See Figure 1-2The curtain lower beam system of this embodiment includes a U-shaped lower beam 1, each end of the U-shaped lower beam 1 is equipped with an integrated lower beam head 2, a cavity is provided in the middle of the U-shaped lower beam 1, a balance rod 3 is provided inside the cavity, the lower beam head 2 is clamped with the U-shaped lower beam 1, and the balance rod 3 is connected to the lower beam head 2; the outer surface of the U-shaped lower beam 1 is covered with a wrapping cloth 4.

[0027] Specifically, a cylindrical boss 2-1 is provided on the side of the lower beam seal 2 facing the balance bar 3. The balance bar 3 is a tubular structure. The cylindrical boss 2-1 is inserted into the end of the balance bar 3 and cooperates with the balance bar 3. In this embodiment, the cylindrical boss 2-1 is rotatably connected to the balance bar 3. The lower beam seal 2 is made of nylon plastic, so that the rotational cooperation between the lower beam seal 2 and the balance bar 3 is smoother. The curtain body bypasses the balance bar 3. When the curtain body is retracted and released, there is friction between the curtain body and the balance bar 3, causing the balance bar 3 to rotate.

[0028] A plurality of limiting beams 1-1 are arranged on the inner wall of the U-shaped lower beam 1, and a limiting cavity is formed between the U-shaped lower beam 1 and the plurality of limiting beams 1-1. A limiting strip 2-2 is arranged on the side of the lower beam head 2 facing the U-shaped lower beam 1, and the limiting strip 2-2 is inserted into the limiting cavity. The end of the limiting strip 2-2 abuts against the limiting beam 1-1, thereby limiting the axial rotation between the U-shaped lower beam 1 and the lower beam head 2.

[0029] A cloth-entrapment groove 1-2 opening toward the cavity is provided at the top of one side of the U-shaped lower beam 1, and a cloth-hiding groove 1-3 opening away from the cavity is provided at the top of the other side of the U-shaped lower beam 1. Clamping strips 5 are fixed at both ends of the wrapping cloth 4. First, one clamping strip 5 is clamped into the cloth-entrapment groove 1-2. After the wrapping cloth 4 goes around the outer surface of the U-shaped lower beam 1, another clamping strip 5 is clamped into the cloth-hiding groove 1-3 to prevent the excess wrapping cloth 4 from being exposed. Both ends of the wrapping cloth 4 are clamped into the groove through the clamping strips 5, so that the wrapping cloth 4 covering the outer surface of the U-shaped lower beam 1 is in a tight state to prevent wrinkles from affecting the appearance.

[0030] The utility model directly cooperates with the lower beam head 2 and the balance rod 3, eliminating the round lower beam head, which not only saves production costs but also simplifies the subsequent assembly process. A wrapping cloth 4 is provided on the outer surface of the U-shaped lower beam 1 to make the U-shaped lower beam 1 consistent with the color of the curtain fabric, thereby increasing the overall aesthetics.

[0031] 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.
