Description

Technical Field

[0001] The utility model relates to the technical field of Roman blinds, and specifically relates to an arc-shaped Roman blind. Background Art

[0002] An arc-shaped Roman blind is a kind of curtain, whose bottom edge is arc-shaped, opposite to the Roman blind with a straight bottom edge. This kind of curtain is usually used for window decoration. The opening and closing degree of the curtain can be adjusted by pulling a thin line to achieve the effect of adjusting indoor light. The arc-shaped Roman blinds come in various styles and can be selected according to different decoration styles and requirements. When installing the arc-shaped Roman blind, the size and shape of the window need to be considered to ensure that the curtain can completely cover the window and present the best decorative effect.

[0003] However, for an extra-long Roman blind, during the installation process, the driving connection problem needs to be considered. Moreover, only using the form of thin line adjustment to control the opening and closing degree of the curtain will also lose safety due to the excessive weight of the arc-shaped Roman blind with too large a specification, resulting in the loss of safety of the form driven by a thin string.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The embodiment of the utility model provides an arc-shaped Roman blind, as Figures 1-5As shown in the figure, it includes a mounting base plate 101. The mounting base plate 101 is arc-shaped. Threaded holes are provided at the top ends on both sides of the mounting base plate 101 for easy installation and connection. Two vertically arranged support mounting plates 104 are fixedly provided on both sides of the lower end surface of the mounting base plate 101. The positions of the support mounting plates 104 on both sides are symmetrical. A number of rotating cylinders 106 are rotatably provided between the support mounting plates 104. The rotating cylinders 106 are evenly distributed along the arc of the mounting base plate 101. Both ends of the rotating cylinder 106 are connected to the tops of the support mounting plates 104 on both sides. Adjacent rotating cylinders 106 on both sides are hinged by a hinge rod 110.

[0024] Further, a support sleeve 107 is sleeved on the outer end surface of each rotating cylinder 106. A number of curtain fabrics 103 are provided below the support sleeve 107. The curtain fabrics 103 are arranged in a hierarchical matrix from top to bottom.

[0025] It should be further noted that the curtain fabrics 103 are arranged in multiple layers according to the installation length.

[0026] Further, the outer end surface of the top curtain fabric 103 is connected to the surface of the support sleeve 107. An arc-shaped connecting plate 105 is connected between adjacent curtain fabrics 103 on both sides.

[0027] Further, a number of round hole guide plates 108 are fixedly provided on the outer end surface of the arc-shaped connecting plate 105. A lifting rope 102 is connected between the vertical round hole guide plates 108.

[0028] Further, the top end of the lifting rope 102 extends upward and is fixedly connected to the surface of the support sleeve 107.

[0029] Further, a lifting and lowering rod 109 for edge sealing is fixedly connected to the lower end of the bottom curtain fabric 103. The lower end of the lifting rope 102 is fixedly connected to the upper end surface of the lifting and lowering rod 109.

[0030] It is worth further noting that a power driving component is connected to one end of the support sleeve 107. The power driving component can be manually driven or electrically driven. The electric drive is a driving motor, and the driving motor can drive the rotating cylinder 106 to rotate.

[0031] When using this solution, first drive the mounting base plate 101 to move to the arc-shaped window frame, which is suitable for the installation of the arc-shaped Roman blind. At this time, through the threaded holes on the surface of the mounting base plate 101, the mounting base plate 101 is stably installed on the top of the window frame. Then, after stably installing the support mounting plates 104 on both sides to both sides of the lower end of the mounting base plate 101, at this time, install the rotating cylinders 106 on both sides between the support mounting plates 104 on both sides, and connect them by hinge rods 110 between adjacent rotating cylinders 106 on both sides.

[0032] At this time, according to the driving requirements, the driving components are installed on the supporting mounting plates 104 on both sides and are power-connected to the rotating cylinders 106 on both sides. Subsequently, the curtain fabric 103 is installed horizontally, and multi-level arrangements are made according to the installation length. An arc-shaped connecting plate 105 is provided between adjacent curtain fabrics 103 for connection, and a lifting and lowering rod 109 for edge sealing is installed at the bottom curtain fabric 103. At the same time, the lifting and lowering rod 109 serves as a lifting and guiding movement.

[0033] After the installation and arrangement are completed, the lifting ropes 102 are passed through the round hole guide plates 108 on each side and are stably connected to the lifting and lowering rod 109 at the bottom. Subsequently, the top of the lifting rope 102 is connected to the rotating cylinder 106.

[0034] When the curtain fabric 103 is lifted and lowered, at this time, the driving component drives the rotating cylinder 106 to rotate. The rotating cylinders 106 are articulated and driven through the articulated rod 110, thereby driving the rotating cylinders 106 on each side to rotate. At this time, through the rotation of the rotating cylinder 106, the lifting ropes 102 on each side are pulled upward, and the arc-shaped lifting and lowering rod 109 at the bottom is pulled upward to move, thereby driving the curtain fabrics 103 on each side to gradually contract from bottom to top and stop after moving to the upper limit position, thereby completing the tightening work of the curtain fabric 103.

[0035] During this process, through the connection between the arc-shaped connecting plates 105 on each side and the support and guidance of the round hole guide plates 108, the lifting stability of the lifting ropes 102 is improved, preventing the lifting ropes 102 from detaching from the surface of the curtain fabric 103, and the connection stability is achieved through the arc-shaped connecting plates 105 on each side, thereby realizing the lifting work of the arc-shaped Roman blinds.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
