Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a blind curtain. Background Art

[0002] The existing blinds are relatively common, such as the three-dimensional blinds with patent number 202023322556.2. Figure 1 ,like Figure 1 As shown, it includes an upper beam 1 and a bottom strip 3 arranged parallel to the upper beam 1. The upper beam 1 is provided with a hanging rope fixed to the upper end thereof, and a plurality of blades 2 are fixedly connected to the hanging rope. The blades 2 are in strip shape and arranged parallel to the upper beam 1. The blades 2 are unfolded to form a closed curtain to block the light from the window. The switching of the open and closed states of the blades 2 needs to be achieved by driving the blades 2 by the hanging rope. In the prior art, there are rubber gaskets between the interlaced holes of the upper beam 1 and the hanging rope to prevent the hanging rope from being worn and broken. However, when there is a strong wind outside the window, the curtain will not only be blown with a large amplitude, but also cause friction between the hanging rope and the two sides of the upper beam 1. When the window is opened for a long time under strong wind conditions, the hanging rope will be broken.

[0003] Therefore, it is necessary to develop a venetian blind that prevents the hanging rope from being worn. Utility Model Content

DETAILED DESCRIPTION

[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Figure 3 A three-dimensional diagram of the optimal embodiment of the top connection frame and the clamping structure of the utility model; Figure 4 For the utility model Figure 3 The enlarged structural diagram at A in the figure. Figures 2 to 4 As shown, the utility model provides a venetian blind, comprising: a top connecting beam 100, a bottom connecting beam 200, a wire pulling structure 300 and a plurality of louvers 400 arranged on the wire pulling structure 300, the bottom connecting beam 200 is arranged at the bottom of the wire pulling structure 300, and at the same time abuts against the bottom louver 400, a wire threading hole 101 is opened on the top connecting beam 100, a clamping structure 500 is arranged on the top connecting beam 100, a part of the wire pulling structure 300 passes through the wire threading hole 101 and extends to the bottom of the clamping structure 500, the clamping structure 500 can not only allow the venetian blind to be quickly removed from the top surface in use, but also prevent the wire pulling structure 300 from shaking too much and causing friction with the top connecting beam 100.

[0027] Please continue reading Figure 4 Combined with Figure 5 , Figure 5 This is an exploded view of the optimal embodiment of the clamping structure of the utility model. Figures 4 to 5As shown, the composition structure of the clamping structure 500 is specifically described below. The clamping structure 500 includes a U-shaped mounting block 501, the opening of the U-shaped mounting block 501 faces downward, and a mounting hole is opened on the top of the U-shaped mounting block 501 for mounting the blinds on the top surface in use. The U-shaped mounting block 501 is sleeved on the top connecting beam 100. Specifically, it is necessary to first fix the U-shaped mounting block 501 on a suitable mounting surface, and then clamp the top connecting beam 100 in the U-shaped mounting block 501, and the opening of the U-shaped mounting block 501 faces the direction of the bottom connecting beam 200. In addition, the U-shaped mounting block 501 covers the position of the threading hole 101. Therefore, the U-shaped mounting block 501 covers the sides of the top connecting beam 100 on both sides of the threading hole 101, which effectively avoids the excessive shaking of the wire pulling structure 300 and can also avoid direct contact with the top connecting beam 100. In order to further prevent the wire pulling structure 300 and the U-shaped mounting block 501 from being worn, arc surfaces 502 are provided on both inner side walls of the opening of the U-shaped mounting block 501. In this way, the wire pulling structure 300 and the arc surfaces will collide with each other when the curtain swings back and forth. It should be further explained that an elastic protective structure is provided on the arc surface 502, and the elastic protective structure is a silicone pad.

[0028] Please continue reading Figure 4 Combined with Figure 5 .like Figures 4 to 5 As shown, two limiting grooves 503 are provided on one side of the inner wall of the clamping structure 500. An insertion hole 504 is provided on the other side of the inner wall of the clamping structure 500, and the inner contour of the insertion hole 504 coincides with the inner contour of the limiting groove 503. The clamping structure 500 includes a U-shaped clamping strip 505. In the installed state, one end of the U-shaped clamping strip 505 enters from the insertion hole 504 and extends into the limiting groove 503. A chamfered surface is provided on one end of the U-shaped clamping strip 505 to facilitate alignment of the insertion hole 504 and the limiting groove 503. The top edge lines of the limiting groove 503 and the insertion hole 504 coincide with each other, and the distance from the top of the limiting groove 503 to the top of the U-shaped mounting block 501 is consistent with the thickness of the top connecting beam 100. After the top connecting beam 100 is inserted into the U-shaped mounting block 501, the U-shaped clip 505 is inserted to relatively fix the top connecting beam 100, so that the curtain as a whole can be stably fixed on the top surface in use, and the curtain can also be easily removed for cleaning.

[0029] In summary, the beneficial effects of the utility model are as follows: by providing the U-shaped clip 505 and the arc surface 502, the excessive shaking amplitude of the pull wire structure 300 is avoided, and at the same time, the friction between the pull wire structure 300 and the two sides of the bottom of the top connecting beam 100 is prevented, thereby enhancing the stability of the curtain during use; by providing the U-shaped clip 505, the top connecting beam 100 can be simply and quickly assembled on the use surface, and at the same time, the curtain can be easily disassembled and washed.
