Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curtain structure, and particularly relates to a honeycomb curtain. BACKGROUND

[0002] The honeycomb curtain is also called an organ curtain, which is similar to the shape of a hand organ in appearance and looks like a honeycomb. The biggest advantage of the honeycomb curtain is that it can meet various needs of various types of household windows, such as corner windows, oval arc windows, floor windows, inclined roof windows, and even overhead skylights. The unique honeycomb structure of the honeycomb curtain can store air in the hollow layer and keep the indoor temperature constant.

[0003] The honeycomb curtain generally comprises a curtain rod, a foldable curtain body, a pull rope and the like. The curtain body comprises a plurality of foldable units connected in sequence. Each foldable unit of the curtain body is provided with a through hole. The pull rope passes through the through hole of each foldable unit. The lower end of the curtain body is pulled up or lowered by the pull rope, so that the foldable units are folded or unfolded, thereby realizing the opening and closing of the honeycomb curtain.

[0004] However, the current honeycomb curtain generally has the following shortcomings: 1. The curtain body of the current honeycomb curtain is generally formed by bonding a plurality of quadrilateral or hexagonal structure unit curtains (for details, refer to patents CN105804623A and CN211524647U, etc.). The manufacturing process is complex, the manufacturing efficiency is low, and the position between the upper and lower unit curtains is prone to deviation during bonding. In addition, the unit curtains are prone to delamination during long-term use, thereby affecting the appearance and service life of the honeycomb curtain. 2. The curtain rod of the honeycomb curtain is generally provided with a damping mechanism, and the pull rope is connected to the damping mechanism. When the curtain body needs to be positioned at the current position after being pulled up to a certain position, the damping mechanism is used to position the pull rope at the current position, thereby realizing the positioning of the curtain body. However, the existing damping mechanism generally has a complex structure, which increases the production cost, and the damping mechanism is a wearing part, which is prone to damage during use, thereby shortening the service life of the honeycomb curtain. SUMMARY

[0005] The present application aims to provide a honeycomb curtain with a simple structure and manufacturing process, stable and reliable structure, and improved production efficiency and service life.

[0006] The present application provides a honeycomb curtain, which comprises two symmetrical pleated curtain units. Each pleated curtain unit comprises a pleated curtain cloth, and the pleated curtain cloth comprises a plurality of foldable units connected in sequence. The two pleated curtain units are connected by a connecting piece, and the pleated curtain cloths of the two pleated curtain units jointly form the curtain body of the honeycomb curtain.

[0007] In an implementation, each of the folding units is in a V-shaped structure, and a V-shaped groove is formed between two adjacent folding units, and the connecting member is arranged corresponding to the V-shaped groove; when the curtain body of the cellular shade is folded, the connecting member can be accommodated in the V-shaped groove.

[0008] In an implementation, each of the pleated shade units further comprises a pull rope, and the pull rope is connected to multiple folding units in the pleated shade cloth; the pull ropes of two pleated shade units are connected through the connecting member.

[0009] In an implementation, a convex ring part is arranged on each of the folding units, and the convex ring part is located on a side of the folding unit on which the two pleated shade units are close to each other, and the pull rope passes through the convex ring parts on multiple folding units; the pull rope is located between the pleated shade cloths of the two pleated shade units.

[0010] In an implementation, the pleated shade cloth is woven by multiple wires, the convex ring part is in an integral structure with the wires, and the convex ring part is formed by bending and protruding from the surface of the pleated shade cloth at a part position of the wires.

[0011] In an implementation, the convex ring part is fixed to the surface of the pleated shade cloth by adhesion.

[0012] In an implementation, a folding edge is formed at the bending part of the folding unit, and the convex ring part is arranged on the folding edge of each folding unit.

[0013] In an implementation, the connecting member is in a ring structure, and the pull ropes of the two pleated shade units pass through the connecting member, so that the pull ropes of the two pleated shade units are connected together through the connecting member.

[0014] In an implementation, each of the pleated shade units further comprises a pull rope, and the pull rope is connected to multiple folding units in the pleated shade cloth; the cellular shade further comprises a curtain rod, the pleated shade cloth is connected to the curtain rod, a damping member is arranged on the curtain rod, and the damping member is fixed to the curtain rod; a through hole is arranged on the damping member and penetrates through the damping member; the pull rope passes through the through hole, and the pull rope is in contact with the inner wall of the through hole; the pull rope can move relative to the damping member in the through hole when subjected to external pulling force, and is fixed to the damping member under the action of friction after losing the external pulling force.

[0015] In an implementation, there is a gap between the pleated shade cloths of the two pleated shade units, and a heat insulation cavity is formed in the space between the pleated shade cloths of the two pleated shade units.

[0016] The honeycomb shade provided by the present invention comprises two symmetrically arranged pleated shade units, which are equivalent to existing pleated shades. Due to the unique V-shaped bend structure of the pleated shade fabric, the pleated shade fabrics of the two units, when connected, can collectively form a honeycomb structure, i.e., the pleated shade fabrics of the two units collectively constitute the shade body of the honeycomb shade. The present invention creatively connects two pleated shades to form the shade body of the honeycomb shade, and uses a connector to connect the two together, eliminating the need for traditional gluing processes. This not only greatly simplifies the manufacturing process and improves production efficiency, but also provides a stable and reliable structure, extending the service life of the honeycomb shade.

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] The terms "first," "second," "third," "fourth," and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequential order or sequence.

[0034] The directional terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of the present invention are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are intended only for clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in the present invention.

[0035] like Figures 1 to 4 As shown, the honeycomb shade provided by an embodiment of the present invention includes two symmetrically arranged pleated shade units 1. These pleated shade units 1 can be conventional pleated shades. Each pleated shade unit 1 includes a pleated shade fabric 11, which includes a plurality of sequentially connected folding units 111. The two pleated shade units 1 are connected by a connector 2, and the pleated shade fabrics 11 of the two pleated shade units 1 together form the shade body of the honeycomb shade.

[0036] Specifically, the honeycomb curtain provided by the embodiment comprises two symmetrical pleated curtain units 1, which are equivalent to the existing pleated curtains. Due to the special V-shaped bending structure of the pleated curtain cloth 11, the pleated curtain cloth 11 of the two pleated curtain units 1 can form a honeycomb structure after being connected, that is, the pleated curtain cloth 11 of the two pleated curtain units 1 constitutes the curtain body of the honeycomb curtain. The honeycomb curtain body is formed by connecting the two pleated curtains, and the two pleated curtains are connected by the connecting piece 2. The traditional gluing process is not needed (the pleated curtain only needs to be bent to form a plurality of folding units 111), which greatly simplifies the manufacturing process, improves the production efficiency, and improves the service life of the honeycomb curtain.

[0037] As shown in Figure 1 and Figure 2 , as an embodiment, the pleated curtain cloth 11 of the two pleated curtain units 1 has a gap, and the space between the pleated curtain cloth 11 of the two pleated curtain units 1 forms a heat insulation cavity 100, thereby improving the heat insulation effect of the honeycomb curtain.

[0038] As shown in Figure 2 and Figure 3 , as an embodiment, each pleated curtain unit 1 further comprises a pull rope 12, and the pull rope 12 is connected with a plurality of folding units 111 in the pleated curtain cloth 11. The pull ropes 12 of the two pleated curtain units 1 are connected by the connecting piece 2. When the pull rope 12 is pulled, the pull rope 12 can drive each folding unit 111 to fold together or stretch out, thereby realizing the opening and closing of the pleated curtain cloth 11, and further realizing the opening and closing of the curtain body of the honeycomb curtain.

[0039] As shown in Figure 2 and Figure 3 , as an embodiment, each folding unit 111 is provided with a convex ring part 112, and the convex ring part 112 is located on the side of the folding unit 111 close to the other pleated curtain unit 1. The pull rope 12 passes through the convex ring part 112 of the plurality of folding units 111, thereby realizing the connection between the pull rope 12 and the plurality of folding units 111 in the pleated curtain cloth 11. At the same time, the pull rope 12 is located between the pleated curtain cloth 11 of the two pleated curtain units 1, thereby achieving the effect of hiding the pull rope 12 and improving the aesthetic degree of the honeycomb curtain.

[0040] Specifically, the existing pleated curtain is generally punched on each folding unit 111, and then the pull rope 12 is passed through the hole on each folding unit 111, so as to realize the connection of the pull rope 12 and each folding unit 111; but this way not only increases the manufacturing steps and reduces the production efficiency, but also the hole on the curtain cloth affects the light shielding and aesthetic of the curtain cloth. The embodiment sets a convex ring part 112 on each folding unit 111 of the pleated curtain cloth 11 for the pull rope 12 to pass through, so that the curtain cloth does not need to be punched, which not only simplifies the manufacturing process and improves the production efficiency, but also improves the light shielding and aesthetic of the curtain cloth; and as shown in Figure 2 the way can also make the pull ropes 12 of the two pleated curtain units 1 closer, so that the pleated curtain cloths 11 of the two pleated curtain units 1 are more symmetrical and fit.

[0041] Of course, in other embodiments, the connection of the pull rope 12 and each folding unit 111 can also be realized by punching the curtain cloth. As shown in Figure 5 and Figure 6 as another embodiment, each folding unit 111 is provided with a through hole 1110, and the pull rope 12 passes through the through holes 1110 on multiple folding units 111 at the same time, so as to realize the connection of the pull rope 12 and each folding unit 111.

[0042] As shown in Figure 2 and Figure 4 as an embodiment, the connecting piece 2 is in a ring structure, and the pull ropes 12 of the two pleated curtain units 1 pass through the connecting piece 2, so that the pull ropes 12 of the two pleated curtain units 1 are connected together through the connecting piece 2, and the connecting piece 2 can be prevented from falling off the pull rope 12. In the embodiment, the connecting piece 2 is in a circular ring structure, and of course can also be in a square ring structure, a triangular ring structure, or other structures (such as a paper clip).

[0043] Specifically, during installation, the pull rope 12 passes through the convex ring part 112 on each folding unit 111 and the connecting piece 2 at the same time, so as to realize the connection between the pull rope 12 and the convex ring part 112 and the connecting piece 2.

[0044] In other embodiments, the pleated curtain cloths 11 of the two pleated curtain units 1 can also be directly connected through the connecting piece 2. For example, the corresponding convex ring parts 112 on the two pleated curtain units 1 are connected through the connecting piece 2.

[0045] As shown in Figure 3As shown, as an embodiment, a folded edge 111b is formed at the bend of each folding unit 111, and a convex ring portion 112 is provided on the folded edge 111b of each folding unit 111. By providing the convex ring portion 112 on the folded edge 111b of the folding unit 111, it is easy for the drawstring 12 to pass through the convex ring portion 112 without affecting the normal folding and unfolding of the folding unit 111.

[0046] like Figure 3 As shown, as an embodiment, each folding unit 111 is provided with two convex ring portions 112, and the two convex ring portions 112 are spaced apart on the folding unit 111. The two convex ring portions 112 are spaced apart on the folded edge 111b of the folding unit 111. Each pleated curtain unit 1 includes two drawstrings 12, and the two drawstrings 12 pass through the two convex ring portions 112 on each folding unit 111, respectively. The two convex ring portions 112 on each folding unit 111 are respectively disposed near the two side edges of the pleated curtain fabric 11, and therefore the two drawstrings 12 are also respectively disposed near the two side edges of the pleated curtain fabric 11.

[0047] like Figure 2 As shown, as an embodiment, two pleated curtain units 1 are connected via a plurality of connectors 2, and the plurality of connectors 2 are spaced apart in the up-down direction.

[0048] like Figure 2 and Figure 5 As shown in FIG. 1 , as an embodiment, each folding unit 111 is a V-shaped structure, and a V-shaped groove 111a is formed between two adjacent folding units 111. Since the two pleated curtain units 1 are symmetrically arranged, the corresponding V-shaped grooves 111a on the two pleated curtain units 1 are also symmetrically arranged, thereby forming a honeycomb structure. The connecting member 2 is arranged corresponding to the V-shaped groove 111a (the connecting member 2 is located between the two adjacent convex ring portions 112 above and below); when the curtain body of the honeycomb curtain is folded (that is, when the pleated curtain fabric 11 is folded), the connecting member 2 can be accommodated in the V-shaped groove 111a (such as Figure 5 As shown, especially when the size of the connecting member 2 is large, the opposite ends of the connecting member 2 can be clearly accommodated in the V-shaped grooves 111a on both sides), thereby avoiding interference between the connecting member 2 and the pleated curtain fabric 11 and affecting the normal folding and unfolding functions of the honeycomb curtain.

[0049] like Figure 9 and Figure 10As shown, as an embodiment, the shade cloth 11 is woven by a plurality of threads 110 (i.e. the shade cloth 11 is a woven fabric), the convex ring portion 112 is an integral structure with the threads 110 (i.e. the convex ring portion 112 is a part of the threads 110, and the convex ring portion 112 is an integral structure with the shade cloth 11), and the convex ring portion 112 is formed by bending and protruding part of the threads 110 from the surface of the shade cloth 11. The shade cloth 11 can be a woven fabric woven by plain weave, twill weave or satin weave, etc.

[0050] As shown in Figure 9 and Figure 10 As an embodiment, the plurality of threads 110 includes a plurality of warp threads 1101 and a plurality of weft threads 1102, and the shade cloth 11 is woven by the plurality of warp threads 1101 and the plurality of weft threads 1102; the convex ring portion 112 is formed by bending and protruding part of the warp threads 1101 or the weft threads 1102 from the surface of the shade cloth 11.

[0051] As shown in Figure 9 and Figure 10 As a preferred embodiment, the convex ring portion 112 is formed by bending and protruding part of the warp threads 1101 from the surface of the shade cloth 11. Of course, in other embodiments, the convex ring portion 112 can also be formed by bending and protruding part of the weft threads 1102 from the surface of the shade cloth 11; or the convex ring portion 112 is formed by bending and protruding part of the warp threads 1101 and the weft threads 1102 from the surface of the shade cloth 11.

[0052] Specifically, the convex ring portion 112 on the shade cloth 11 can be formed by hooking out part of the threads 110 in the shade cloth 11 with a hook or other tools, so that part of the threads 110 protrude from the surface of the shade cloth 11, thereby forming the convex ring portion 112. The forming process of the convex ring portion 112 on the shade cloth 11 can refer to the forming process of the convex ring portion 112 on the shade cloth 11 shown in Figures 7 to 10 As shown in Figure 7 and Figure 8 When the convex ring portion 112 has not been formed on the shade cloth 11, the surface of the shade cloth 11 is flat, and the threads 110 in the shade cloth 11 do not protrude from the surface of the shade cloth 11; as shown in Figure 9 and Figure 10As shown, when forming the convex ring portion 112 on the pleated curtain 11, a hook or other tool can be used to hook out the warp 1101 in the pleated curtain 11, so that part of the warp 1101 is bent and protrudes from the surface of the pleated curtain 11, thereby forming the convex ring portion 112 on the pleated curtain 11, and the draw cord 12 can pass through the convex ring portion 112 (of course, in other embodiments, a hook or other tool can also be used to hook out the weft 1102 in the pleated curtain 11 to form the convex ring portion 112; or the warp 1101 and weft 1102 in the pleated curtain 11 can be hooked out at the same time to form the convex ring portion 112). This production method is simple in process, does not require punching the pleated curtain 11, does not require additional structural parts to be set on the pleated curtain 11, and does not damage the structure of the pleated curtain 11, thereby simplifying the production process and improving the light-shielding and aesthetic properties of the curtain.

[0053] As another embodiment, the convex ring portion 112 and the pleated curtain fabric 11 can also be separate structures (i.e., the convex ring portion 112 and the pleated curtain fabric 11 are two separate components), and the convex ring portion 112 is fixed to the surface of the pleated curtain fabric 11 by bonding. During manufacturing, a silk thread (of course, the convex ring portion 112 can also be made of other materials) can be bonded to the surface of the pleated curtain fabric 11 to form the convex ring portion 112.

[0054] like Figure 1 、 Figure 11 and Figure 12 As shown, as an embodiment, a honeycomb shade further includes a curtain rod 3, a pleated curtain fabric 11 connected to the curtain rod 3, and a damper 4 fixed to the curtain rod 3. The damper 4 has a through-hole 40 extending through the damper 4. A pull cord 12 passes through the through-hole 40 and contacts the inner wall of the through-hole 40. The pull cord 12 can move relative to the damper 4 within the through-hole 40 when subjected to an external tension. When the external tension is removed, the pull cord 12 is fixed to the damper 4 due to friction. (Due to the contact between the pull cord 12 and the inner wall of the through-hole 40, contact friction exists between the pull cord 12 and the damper 4. When the external tension is less than the contact friction, the pull cord 12 is fixed to the damper 4. When the external tension is greater than the contact friction, the pull cord 12 is able to move relative to the damper 4.)

[0055] Specifically, this embodiment provides a damping member 4 on the curtain rod 3 and a through-hole 40 on the damping member 4. The pull cord 12 passes through the through-hole 40 and contacts the inner wall of the through-hole 40. This allows the pull cord 12 to be fixed to the damping member 4 by friction. Furthermore, when subjected to an external tensile force, the pull cord 12 can move relative to the damping member 4 within the through-hole 40, thereby achieving relative movement and locking between the pull cord 12 and the damping member 4. This damping mechanism has a simple structure and is easy to assemble, which not only reduces production costs, simplifies the production process, and improves production efficiency, but also allows for easy replacement of the damping member 4 if damaged (simply by removing and replacing it). Furthermore, the structure is stable and reliable, which helps extend the service life of the cellular shade.

[0056] As an embodiment, the diameter of the through hole 40 is smaller than (slightly smaller than) the outer diameter of the pull rope 12, and the outer wall of the pull rope 12 can be fixed by contacting the inner wall of the through hole 40 through extrusion. Specifically, since the diameter of the through hole 40 is smaller than the outer diameter of the pull rope 12, when the pull rope 12 is installed in the through hole 40 on the damping member 4, an extrusion force is generated between the outer wall of the pull rope 12 and the inner wall of the through hole 40, which in turn generates a contact friction force between the outer wall of the pull rope 12 and the inner wall of the through hole 40. Therefore, the pull rope 12 will not produce relative movement with the damping member 4 when no external force is applied. At the same time, the pull rope 12 is generally made of a flexible material, so the portion of the pull rope 12 located in the through hole 40 will deform under the action of the extrusion force, so that the pull rope 12 and the inner wall of the through hole 40 can better fit, generating a more stable contact friction force.

[0057] As an embodiment, the pull cords 12 of the two pleated curtain units 1 can pass through the same damping member 4 (for example, the two pull cords 12 corresponding to the two pleated curtain units 1 pass through the same through hole 40 on the damping member 4; or, each damping member 4 is provided with two through holes 40, and the two pull cords 12 corresponding to the two pleated curtain units 1 pass through the two through holes 40 on the damping member 4 respectively), or they can pass through different damping members 4 respectively.

[0058] like Figure 11 and Figure 12 As shown, as one embodiment, the damping member 4 includes a fixing block 41, which is disposed on and fixed to the curtain rod 3. A through hole 40 is provided in the fixing block 41 and extends through the fixing block 41. The pull cord 12 passes through the through hole 40 of the fixing block 41. The pull cord 12 can move within the through hole 40 relative to the fixing block 41 when subjected to an external tension. After the external tension is removed, the pull cord 12 is fixed to the fixing block 41 due to friction.

[0059] As an implementation, the fixing block 41 is made of elastic material, such as soft plastic, soft silica gel, soft rubber, etc. In this way, when the pull rope 12 is pulled, the fixing block 41 can be deformed to a certain extent (slightly), thereby avoiding rigid friction between the fixing block 41 and the pull rope 12, reducing the wear of the fixing block 41 and the pull rope 12, and prolonging the service life of the fixing block 41 and the pull rope 12. Of course, in other embodiments, the fixing block 41 can also be made of hard material, such as hard plastic, metal, etc.

[0060] As another implementation, the fixing block 41 is made of wear-resistant material, such as wear-resistant metal material (e.g., wear-resistant steel, wear-resistant cast iron, etc.), wear-resistant plastic material, wear-resistant rubber material, or wear-resistant ceramic material, etc. In this way, the service life of the fixing block 41 can also be prolonged.

[0061] As shown in Figures 13 to 15 As another implementation, the damping member 4 includes a fixing block 41 and a wear-resistant sleeve 42 of a cylindrical structure, the fixing block 41 is arranged on the curtain rod 3 and fixed thereto. The fixing block 41 is provided with a through hole 411 penetrating the fixing block 41, and the wear-resistant sleeve 42 is arranged in the through hole 411 of the fixing block 41 and fixed thereto. The through hole 40 is arranged on the wear-resistant sleeve 42, the pull rope 12 passes through the through hole 40 on the wear-resistant sleeve 42. The pull rope 12 can move relative to the wear-resistant sleeve 42 in the through hole 40 when subjected to external tension, and be fixed relative to the wear-resistant sleeve 42 under the action of friction after losing external tension.

[0062] Specifically, by arranging the wear-resistant sleeve 42 in the fixing block 41, the wear-resistant sleeve 42 is used to contact and rub with the pull rope 12, i.e., the pull rope 12 does not directly contact the fixing block 41, and the wear-resistant sleeve 42 has good wear resistance, thereby prolonging the service life of the damping member 4.

[0063] As an implementation, the wear-resistant sleeve 42 is made of wear-resistant material, such as wear-resistant metal material (e.g., wear-resistant steel, wear-resistant cast iron, etc.), wear-resistant ceramic material, etc.

[0064] As an implementation, the wear-resistant sleeve 42 and the fixing block 41 can be fixedly connected by glue, or can be fixed by interference fit (i.e., the outer diameter of the wear-resistant sleeve 42 is slightly larger than the inner diameter of the through hole 411), clamping, etc.

[0065] As shown in Figure 11 and Figure 12As shown, as an embodiment, the curtain rod 3 is provided with a mounting groove 30, and the fixing block 41 is clamped in the mounting groove 30. The mounting groove 30 extends along the length direction of the curtain rod 3, and the end of the curtain rod 3 is provided with an opening 300 which is communicated with the mounting groove 30, and the opening 300 is used for sliding the fixing block 41 into the mounting groove 30.

[0066] Specifically, when installing the fixing block 41, it is only needed to slide the fixing block 41 into the mounting groove 30 from the opening 300, and then slide the fixing block 41 in the mounting groove 30 to the required installation position, so as to facilitate the installation, and the fixing block 41 will not easily fall off from the mounting groove 30.

[0067] As an embodiment, the curtain rod 3 is a profile, and the whole curtain rod 3 is an integral structure.

[0068] As shown in Figure 11 and Figure 12 , as an embodiment, the fixing block 41 and the curtain rod 3 are further fixed by the fixing member 5.

[0069] Specifically, as shown in Figure 11 and Figure 12 , in the embodiment, the fixing member 5 is a screw; the fixing block 41 is provided with a screw hole 412, the fixing member 5 is located outside the curtain rod 3, the fixing member 5 extends into the curtain rod 3 after passing through the curtain rod 3 (the curtain rod 3 is provided with a hole position for the fixing member 5 to pass through) and is connected with the screw hole 412 on the fixing block 41, so as to further fix and limit the fixing block 41. Of course, in other embodiments, the fixing member 5 can also be other devices, such as a spring, a pin shaft, etc.

[0070] As shown in Figure 11 and Figure 12 , as an embodiment, one end of the pull rope 12 is located outside the curtain rod 3, the other end of the pull rope 12 extends into the curtain rod 3 after passing through the curtain rod 3 (the curtain rod 3 is provided with a hole position for the pull rope 12 to pass through), and then passes through the through hole 40 on the damping member 4 and extends out of the curtain rod 3.

[0071] As shown in Figure 1 and Figure 11 , as an embodiment, the curtain rod 3 is provided with two damping members 4, and the two damping members 4 are spaced apart along the length direction of the curtain rod 3, and the pull rope 12 is respectively arranged on the two damping members 4.

[0072] As shown in Figure 1As shown, as an embodiment, the number of curtain rods 3 is two, which are respectively upper curtain rod and lower curtain rod (not numbered in the figure), the upper curtain rod and the lower curtain rod are arranged in an upper and lower spaced manner, and the upper curtain rod is located above the lower curtain rod. The pleated curtain cloth 11 is located between the upper curtain rod and the lower curtain rod, and the top end of the pleated curtain cloth 11 of the two pleated curtain units 1 is connected with the upper curtain rod at the same time, the bottom end of the pleated curtain cloth 11 of the two pleated curtain units 1 is connected with the lower curtain rod at the same time, the upper curtain rod and the lower curtain rod are both provided with the damping member 4, and the upper and lower ends of the pull rope 12 pass through the damping member 4 on the upper curtain rod and the damping member 4 on the lower curtain rod respectively. Of course, in other embodiments, the damping member 4 can be arranged on only one of the upper curtain rod and the lower curtain rod.

[0073] Specifically, the upper curtain rod is generally fixed on the wall. In use, when the honeycomb curtain needs to be retracted upward, only the upper end of the pull rope 12 (i.e. the end of the pull rope 12 extending to the upper curtain rod) needs to be pulled, at this time, the lower curtain rod moves upward under the pulling action of the pull rope 12 (no relative movement occurs between the lower curtain rod and the pull rope 12), and at the same time, the lower curtain rod pushes each folding unit 111 of the pleated curtain cloth 11 to perform a folding action, so that the pleated curtain cloth 11 is retracted upward (or one hand holds the lower end of the pull rope 12 (i.e. the end of the pull rope 12 extending to the lower curtain rod), and the other hand pushes the lower curtain rod to move upward, so that the lower curtain rod pushes each folding unit 111 of the pleated curtain cloth 11 to perform a folding action, and then the pleated curtain cloth 11 is retracted upward); when the honeycomb curtain is retracted upward to a specified position, the pull rope 12 is released, and the lower curtain rod is locked at the fixed position, at this time, the honeycomb curtain is also positioned at the specified position. When the honeycomb curtain needs to be lowered, only the lower end of the pull rope 12 needs to be pulled downward (or the lower curtain rod is pushed downward), at this time, the lower curtain rod drives each folding unit 111 to perform an unfolding action, so that the pleated curtain cloth 11 is opened, thereby realizing the upward and downward retraction of the honeycomb curtain.

[0074] The honeycomb curtain provided by the embodiment of the present application comprises two symmetrically arranged pleated curtain units 1, which are equivalent to the existing pleated curtain. Due to the special V-shaped bending structure of the pleated curtain cloth 11, the pleated curtain cloth 11 of the two pleated curtain units 1 can form a honeycomb structure after being connected, that is, the pleated curtain cloth 11 of the two pleated curtain units 1 constitutes the curtain body of the honeycomb curtain. The present application creatively uses two pleated curtains to form the curtain body of the honeycomb curtain, and uses the connecting member 2 to connect the two pleated curtains together, without the traditional gluing process (only the bending process is needed for the pleated curtain), which not only greatly simplifies the manufacturing process, improves the production efficiency, but also improves the service life of the honeycomb curtain.

[0075] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
