Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a fabric connecting component and a curtain. Background Technology

[0002] Manually operated curtains (or manually sliding curtains), as a new type of curtain, typically include the following basic structure: a track, curtain slats for mounting the curtain fabric, pulleys for moving the curtain slats within the track, and a pull cord or operating rod. Users pull the pull cord or operating rod to move the curtain slats and pulleys along the track, thus achieving the coordinated opening and closing of multiple curtain slats.

[0003] However, there are two main ways to connect the curtain fabric and slats during the installation of curtains. The first method involves gluing the fabric to the slats. Therefore, when installing the curtain, users need to adjust the fabric size according to the height of the area to be covered, cut it accordingly, and then apply and glue it – a rather cumbersome process. Furthermore, when using glue to glue wider curtains, unevenness is common, and once glued, it's difficult to reshape, resulting in a less than aesthetically pleasing final curtain. The second method involves sewing Velcro onto the curtain fabric first, then using the Velcro to attach the fabric to the slats which have matching Velcro. This leaves stitching marks on the fabric, causing unevenness. Additionally, when users attach the curtain to the slats, the fabric and slats are very prone to misalignment, resulting in an overall skewed appearance.

[0004] Therefore, there is an urgent need to provide a fabric connection component to improve the installation method of curtains, so as to solve the problems of cumbersome curtain installation and poor flatness of curtains after installation in the existing technology, thereby improving the user experience and the overall quality of the product. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a fabric connecting component and a curtain that can solve the problems of complicated curtain installation and poor flatness of the curtain after installation in the prior art.

[0006] To achieve the above and other objectives, this utility model is implemented through the following technical solution: As a first aspect, this utility model proposes a fabric connecting assembly, including a core rod for limiting and installing the curtain fabric within a snap-fit ​​component; the snap-fit ​​component includes a snap-fit ​​ring, a straight strip, and a locking strip; the snap-fit ​​ring is used to limit and install the core rod and the curtain fabric, and has an opening thereon for the lower end of the curtain fabric to pass through; the straight strip extends vertically downward at the opening; the opening and the locking strip are respectively located on the front and rear sides of the straight strip, and the included angle between the locking strip and the straight strip is an acute angle.

[0007] In one embodiment, the snap ring, the straight bar, and the snap bar are integrally formed.

[0008] In one embodiment, at least the card strip is made of an elastic material.

[0009] In one embodiment, the length of the card strip is less than the length of the straight strip.

[0010] As a second aspect, the present invention provides an opening and closing curtain, including a fabric connecting assembly as described in the first aspect, which engages with the snap-fit ​​groove of the curtain slats.

[0011] In one embodiment, a protrusion is provided in the snap-fit ​​groove.

[0012] In one embodiment, the distance L2 from the bottom of the protrusion to the upper end of the slot of the snap-fit ​​groove is less than the distance L1 from the bottom of the card strip to the upper end of the opening.

[0013] In one embodiment, when installing the fabric connecting assembly, the side with the locking strip is inserted into the locking groove facing the curtain slat; during installation, the locking strip undergoes elastic deformation under force, causing the fabric connecting assembly to be inserted from the opening of the locking groove backward and upward, and after installation, the locking strip returns to its original position and engages with the protrusion to lock tightly.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The fabric connecting component provided by this utility model has a simple structure. Compared with the traditional method of using glue or Velcro to attach the curtain, the way the curtain is installed allows users to easily adjust the folding length of the upper end of the curtain according to the height of the area to be covered. This not only saves the tedious operations of cutting the curtain and applying glue or sewing Velcro, but also allows the fabric to be shaped by adjusting the lower end of the curtain when the flatness of the curtain is not good, thus ensuring the flatness of the curtain.

[0016] 2. The structural design of the fabric connection component provided by this utility model allows the installation of the curtain fabric to be carried out after the curtain slats are installed in the track, avoiding the problems of complex assembly process and large overall weight leading to high labor intensity when the curtain fabric and curtain slats are installed together in the track in the prior art.

[0017] 3. The protrusion inside the snap-fit ​​groove of this utility model can effectively prevent the fabric connecting component from coming off.

[0018] 4. The design of the relationship between distances L1 and L2 in this utility model ensures that the fabric connecting component will not come out after being installed on the curtain slat, and can also shape the curtain fabric extending from the snap ring. Attached Figure Description

[0025] To avoid confusion with this utility model, some technical features known in the art have not been described.

[0026] Example 1:

[0027] like Figure 1As shown, this embodiment provides a fabric connection assembly including a core rod 10 and a snap-fit ​​component 20. The core rod 10 is a cylinder, which can be solid or hollow, and is used to limit the installation of the curtain fabric 30 within the snap-fit ​​component 20. The side projection shape of the snap-fit ​​component 20 is R-shaped, including an integrally formed snap-fit ​​ring 21, a straight bar 22, and a snap-fit ​​strip 23. The snap-fit ​​ring 21 is used to limit the installation of the curtain fabric 30 and the core rod 10, and has an opening 211 for the lower end of the curtain fabric 30 to pass through. The straight bar 22 extends vertically downward at the opening 211 to guide the lower end of the curtain fabric 30 to remain vertical. The opening 211 and the snap-fit ​​strip 23 are respectively located on the front and rear sides of the straight bar 22. The snap-fit ​​strip 23 can be set on the snap-fit ​​ring 21 and / or the straight bar 22, and the included angle formed between the snap-fit ​​strip 23 and the straight bar 22 is an acute angle. The clip 23 is made of an elastic material and is elastic, allowing it to deform elastically to change the angle between itself and the straight bar 22. The length of the clip 23 is less than the length of the straight bar 22.

[0028] When installing the curtain 30 onto the fabric connecting assembly, first fold the excess fabric at the top of the curtain 30 and insert it together with the core rod 20 into the snap ring 21 from the left / right side of the snap member 20, so that the bottom of the curtain 30 can pass through the opening 211. This reliably fixes the curtain 30 to the snap member 20, ensuring that the bottom of the curtain 30 is flat and vertically downward. When it is necessary to remove the curtain 30, simply pass the core rod 20 through the side of the snap ring 21. Compared with the traditional method of using glue or Velcro to attach the curtain 30, this method of installing the curtain 30 allows users to easily adjust the folded length of the top of the curtain 30 according to the height of the area to be covered. It not only eliminates the tedious operations of cutting the curtain 30 and applying glue or sewing Velcro, but also allows for fabric reshaping by adjusting the bottom of the curtain 30 when the flatness of the curtain 30 is not ideal, ensuring the flatness of the curtain 30.

[0029] Example 2:

[0030] Please combine Figure 1-3 This embodiment provides an opening and closing curtain, including a track, a curtain slat 40 with a snap-fit ​​groove 411, a fabric connecting assembly as described in Embodiment 1, and a drive component. The curtain slat 40 slides linearly within the track; the fabric connecting assembly is made of elastic material and snaps into the snap-fit ​​groove 411 of the curtain slat 40 to limit the installation of the curtain fabric 30. The fabric connecting assembly can be installed with the curtain fabric 30 and then snapped into the curtain slat 40, or it can be snapped into the curtain slat 40 first and then installed with the curtain fabric 30; the drive component (e.g., a traction rope or operating rod) is connected to a positioning block on the foremost curtain slat and / or the last curtain slat. The user pulls the drive component to move the curtain slat where the positioning block is located within the track, thereby realizing the coordinated opening or closing of multiple curtain slats.

[0031] When installing the fabric connecting assembly to the slat assembly, insert the snap-fit ​​groove 41 with the side of the snap-fit ​​strip 23 facing the slat 40. During installation, the snap-fit ​​strip 23 undergoes elastic deformation under force, and the fabric connecting assembly is inserted from the opening of the snap-fit ​​groove 41 to the rear and upward. After installation, the snap-fit ​​strip 23 returns to its original position and tightly engages with the protrusion 411 of the snap-fit ​​groove 41.

[0032] Furthermore, the distance L2 from the bottom of the protrusion 411 to the upper end of the slot of the snap-fit ​​groove 41 is designed to be smaller than the distance L1 from the bottom of the snap-fit ​​strip 23 to the upper end of the opening 211. This ensures that the fabric connecting assembly will not come off after being installed on the slat 40, and also allows for the shaping of the fabric 30 extending from the snap-fit ​​ring 21.

[0033] In summary, the fabric connecting assembly provided by this utility model has a simple structure. Compared with traditional methods of using glue or Velcro for attaching curtains, the method of installing the curtain allows users to easily adjust the folded length of the upper end of the curtain according to the height of the area to be covered. This not only eliminates the tedious operations of cutting the curtain and applying glue or sewing Velcro, but also allows for fabric reshaping by adjusting the lower end of the curtain when the curtain's flatness is not ideal, ensuring the curtain's flatness. Furthermore, the structural design of the fabric connecting assembly allows the curtain to be installed after the slats are installed in the track, avoiding the problems of complex assembly processes and high labor intensity caused by the large overall weight when installing the curtain and slats together in the existing technology.

[0034] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
