Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

Example 1:

as shown in fig. 1 to 4, a connection structure of a curtain cloth and a curtain rail includes a curtain rail 1 and a curtain cloth 2. The curtain rail 1 is sized to fit the window frame (not shown) in use. The curtain frame 1 is fixed with the window frame. For convenience of description, the curtain rail 1 of the present embodiment has a rectangular frame structure. The curtain cloth 2 is made of flexible fabric, and can be plastic cloth, textile cloth and the like. The curtain cloth 2 can shield the whole window when being completely unfolded. The curtain rod 1 is provided with a fixing belt 11 and a winding mechanism 12 which correspond to each other in position. As shown in fig. 1, the fastening band 11 is located at the left end of the curtain rod 1, and the winding mechanism 12 is located at the right end of the curtain rod 1. The fixing belt 11 is strip-shaped, the left side of the fixing belt is fixed with the left end of the curtain frame 1, and the right side of the fixing belt is suspended. The suspended side of the fixing belt 11 is provided with zipper teeth 4. The winding mechanism 12 is fixed with the right end of the curtain rod 1. The right end of the curtain cloth 2 is fixed with the winding mechanism 12. The winding mechanism 12 is provided with a rotatable winding rod (not shown). The right end of the curtain cloth 2 is fixed with the winding rod, and when the winding rod rotates, the curtain cloth 2 can be wound on the winding rod or withdrawn from the winding rod. The left end of the curtain cloth 2 is connected with a transition belt 3.

The transition zone 3 is Y-shaped in cross-section (as shown in figure 2). The transition belt 3 includes an upper connecting portion 31, a tooth connecting portion 32, and a lower connecting portion 33. The transition zone 3 is a textile belt. On the left in fig. 2 is a tooth attachment 32. The tooth attachment portion 32 has a plain weave structure. Fig. 3 shows a schematic view of the interlacing of the weft threads 34 with the warp threads 35 of the tooth attachment 32. In the figure, the weft 34 and the warp 35 are in a plain weave of one-over-one-under, but it is also possible to use two-over-two-under plain weaves, but not one-over-one-under plain weave is tight. The tooth connecting portion 32 is embedded with the core rope 5. The core rope 5 is a rope structure with a circular section. The core string 5 is adjacent to the tooth attachment portion 32 side. The core rope 5 is interlaced with the weft 34 of the tooth attachment portion 32, surrounded by the weft 34 of the tooth attachment portion 32, and the entire core rope 5 is embedded in the tooth attachment portion 32 near the left side of the transition belt 3. The transition belt 3 is provided with zipper teeth 4. The fastener element 4 is located on the left side of the element attaching portion 32. The right part of the fastener element 4 is a tooth root that sandwiches the element connecting part 32 of the insert core 5. The left end of the fastener element 4 is a tooth portion exposed to the left side of the element connecting portion 32. The tooth part of the zipper teeth 4 is matched with the tooth part of the zipper teeth 4 arranged on the suspended side of the fixing band 11, and the zipper teeth and the tooth part can be connected or separated through the action of a zipper puller (not shown).

One end of each of the upper connecting portion 31 and the lower connecting portion 33 is fixed to the tooth connecting portion 32, and the other end thereof forms an opening. The right end of the tooth connecting part 32 is connected with the left ends of the upper connecting part 31 and the lower connecting part 33. In the weaving process, starting from the boundary between the right end of the tooth connecting part 32 and the upper connecting part 31 and the lower connecting part 33, the weft 34 of the previous weft is interwoven with the warp 35 of the upper connecting part 31, and the weft 34 of the next weft is interwoven with the warp 35 of the lower connecting part 33. The weft threads 34 of two adjacent wefts are alternately interwoven with the warp threads 35 of the upper connecting part 31 and the warp threads 35 of the lower connecting part 33. The upper connecting portion 31 and the lower connecting portion 33 on the right side of the transition zone 3 are two independent structures, i.e., an upper piece and a lower piece, and form openings.

The upper connecting portion 31 and the lower connecting portion 33 have a tissue structure exposed to the meridians. In order to increase the firmness of the connection between the transition belt 3 and the curtain fabric 2, the warp threads exposed from the upper connection part 32 and the lower connection part 33 are made of the same material as the curtain fabric 2. Fig. 3 shows the upper connecting portion 31 and the lower connecting portion 33 with twill exposed warp weaves for illustration purposes only. The warp yarns 35 of the upper connecting portion 31 are of a four-down two-up warp structure, and the warp yarns 35 are twilled to expose the lower surface of the upper connecting portion 32. Similarly, the warp yarns 35 of the lower connecting portion 33 have a two-over-four warp weave, and the warp yarns 35 are twilled to expose the upper surface of the lower connecting portion 33.

The warp threads exposed out of the upper connecting part 31 and the lower connecting part 33 are matched with the curtain cloth 2. The curtain cloth 2 is fixedly inserted into the opening end. The ends of the curtain cloth 2 are welded or bonded to the upper and

lower connection parts

31 and 33. In fig. 2, the left end of the curtain fabric 2 is inserted into an opening formed by the upper connecting portion 31 and the lower connecting portion 33. If the curtain fabric 2 is made of heat-fusible plastic, the exposed warp threads 35 of the upper and lower connecting

portions

31 and 33 are also made of heat-fusible plastic. When the left end of the curtain fabric 2 is inserted into the opening formed by the upper connecting part 31 and the lower connecting part 33, the warp sinking of the upper connecting part 31 and the warp lifting of the lower connecting part 33 are respectively welded with the two surfaces of the left end of the curtain fabric 2 through hot melting treatment. If the window shade 2 is a woven fabric, the warp yarns 35 exposed at the upper and lower connecting

portions

31, 33 are made of the same material as the woven fabric of the window shade 2. When the left end of the curtain fabric 2 is inserted into the opening formed by the upper connecting part 31 and the lower connecting part 33, the warp sinking of the upper connecting part 31 and the warp lifting of the lower connecting part 33 are respectively bonded with the two surfaces of the left end of the curtain fabric 2 through the adhesive.
