Description

Technical Field

[0001] The utility model relates to a Roman blind structure, in particular to a Roman blind structure with adjustable ends. Background Art

[0002] Roman blinds are new decorations, which can be divided into folding, fan, wave and other types according to their shapes. Roman blinds can create a warmer effect, and are now commonly used in the decoration of high-end entertainment and leisure places such as homes and hotels, and are deeply loved by the public. Roman blinds include manual Roman blinds and electric Roman blinds. They can be divided into folding, fan and wave types according to their shapes. Electric Roman blinds use AC tubular motors, which use speed control devices to make the rope winder on the coaxial axis rotate, pull the lifting rope to rise and fall, and thus achieve the opening and closing of the curtain.

[0003] Roman blinds are a type of curtain decoration. They are made by running a horizontal bar through the fabric, making the fabric look stiff and giving full play to the texture of the fabric. Compared with the roller blinds that also operate by pulling up, Roman blinds have a more layered feel, and the decorative effect is very gorgeous and beautiful, adding an elegant and simple beauty to the window. The existing Roman blinds are basically fixed in size, but there will always be some errors for different window frames, and they cannot be perfectly adapted. Summary of the invention

[0022] The technical solutions of the utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0023] Embodiment:

[0024] As shown in Figure 1 , a Roman blind structure with adjustable ends includes a top plate 2, which is a profile structure. A long groove 22 is formed at the lower end of the top plate 2. End cap structures are installed on both sides of the top plate 2. The end cap structure at one end is telescopic and adjustable, and the end cap structure at the other end is fixed and non-adjustable. The non-adjustable end cap structure includes an end cap mounting box 3, and the cross-section of the end cap mounting box 3 is the same as that of the top plate. On the left, right, and bottom sides of the end face of the end cap mounting box 3, a top plate positioning member 4 is formed respectively, which is used to insert into the top plate profile, so as to connect the end cap structure and the top plate 6 together. A drawstring structure is installed on the end cap to facilitate the installation and operation of the drawstring.

[0025] As shown in Figure 2 and 3 and 4, the telescopic and adjustable end cap structure includes an end cap body 1. The end cap body 1 has a cylindrical receiving cavity 10, and an elastic member is installed in the receiving cavity 10. On the left and right sides outside the receiving cavity 10, a vertical baffle 9 is formed respectively. The bottom end of the baffle 9 is arc-connected to the outer wall of the receiving cavity. The baffle 9 is connected to the cavity wall of the receiving cavity 10 through a support rib 19. The vertical baffle 9 is in contact with the side cavity wall 20 of the top plate cavity, and the upper arc surface of the receiving cavity 10 is in contact with the upper cavity wall 21 of the top plate cavity (as shown in Figure 5 ). An end baffle 8 is formed at the end of the receiving cavity 10, and the end baffle 8 is higher than the receiving cavity 10, which is used to position the end cap body 1 after the end cap body 1 is inserted into the profile cavity of the top plate 6. A lower positioning seat 12 is formed at the bottom of the receiving cavity 10, and the length of the lower positioning seat 12 is slightly longer than the length of the receiving cavity 10. The bottom surface of the lower positioning seat 12 abuts against the inner surface of the long groove 22 of the top plate. A locking position 11 is formed at the end of the lower positioning seat 12, and a thread is formed in the locking position 11. After the end cap body 1 is inserted into the top plate 6, a screw passes through the long groove of the top plate and is fixed on the locking position 11, so as to fix the end cap body 1 and the top plate 6.

[0026] The elastic component within the accommodating cavity includes a piston assembly that abuts against the wall or window frame. The piston assembly is located within the positioning assembly, and the positioning assembly is located within the accommodating cavity. A positioning member 18 is concentrically arranged within the accommodating cavity. One end of the positioning member 18 is formed with an annular outer operation disc 6, and the outer operation disc 6 is located outside the end baffle 8 of the end cover body. A dial groove 7 for the operation of a wrench 5 is formed on the outer operation disc 6. The positioning member 18 also includes a hollow cavity, and a telescopic rod 16 is threadedly connected to the inner wall of the cavity. The telescopic rod 16 also has a hollow cavity, and the cross-section of the telescopic rod 16 is non-circular. A piston rod 15 that cannot rotate relative to the telescopic rod is installed within the cavity of the telescopic rod 16, and the cross-section of the piston rod 15 is the same as that of the telescopic rod. A piston disc 14 is formed at the end of the piston rod 15, and one end of the telescopic rod 16 abuts against the piston disc 14. Through holes are formed at the bottom of the cavity of the telescopic rod 16, at the bottom of the cavity of the positioning member 18, and at the bottom of the accommodating cavity 10. After the end of the piston rod 15 sequentially passes through the through holes at the bottom of the cavity of the telescopic rod and the through holes at the bottom of the cavity of the positioning member, it is located outside the end face of the end cover body 1, and the end of the piston rod 15 is fixed to the outside of the end face of the end cover body 1 by screws. A spring 17 is sleeved on the outer circumference of the portion of the piston rod 15 located within the cavity of the telescopic rod 16. One end of the spring 17 abuts against the piston rod 15, and the other end of the spring 17 abuts against the bottom of the cavity of the telescopic rod 16. A groove is formed on the piston disc 14 to install an elastic pressing disc 13.

[0027] During use, the end cover structures at both ends are installed onto the ejector rod through the ejector rod fixing structure, and then the ejector rod is installed onto the window frame or wall. Since the end cover structure at one end of the ejector rod is adjustable, the pressing disc is abutted against the window frame or wall by compressing the spring, and then a wrench or the outer operation disc is rotated to rotate the positioning member. The rotation of the positioning member drives the telescopic rod to axially move within the cavity of the positioning member, thereby pressing the end of the telescopic rod against the piston disc at the end of the piston rod to lock the piston assembly, thus completing the installation of the Roman blind.

[0028] The specific embodiments described herein are merely illustrative of the concept of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
