The two blind units 1 are connected through a connecting piece 2, and the blind curtain 11 of the two blind units 1 jointly form a curtain body of the honeycomb curtain.

Specifically, the honeycomb curtain provided in this embodiment includes two symmetrically arranged blind units 1, where the blind units 1 are equivalent to the existing blind, and after the two blind units 1 are connected, the blind units 11 of the two blind units 1 can jointly form a honeycomb structure, that is, the blind units 11 of the two blind units 1 jointly form a curtain body of the honeycomb curtain. The invention creatively uses two hundred-fold curtains to be connected with each other to form the curtain body of the honeycomb curtain, and uses the connecting piece 2 to connect the two curtains together, without the traditional cementing process (the hundred-fold curtains only need to be subjected to a bending process, namely the hundred-fold curtains 11 are bent to form a plurality of folding units 111), thereby greatly simplifying the manufacturing process flow, improving the production and manufacturing efficiency, and having stable and reliable structure and prolonging the service life of the honeycomb curtain.

As shown in fig. 1 and 2, as an embodiment, a gap is formed between the blind curtain pieces 11 of the two blind units 1, and a heat insulation cavity 100 is formed in the space between the blind curtain pieces 11 of the two blind units 1, so that the heat insulation effect of the honeycomb curtain is improved.

As shown in fig. 2 and 3, as an embodiment, each pleated cover unit 1 further includes a pull rope 12, and the pull rope 12 is simultaneously connected to a plurality of folding units 111 in the pleated cover 11; the stay cords 12 of the two blind units 1 are connected through a connecting piece 2. When the pull rope 12 is pulled, the pull rope 12 can drive each folding unit 111 to fold together or unfold, so that the shutter curtain 11 is opened and closed, and the curtain body of the honeycomb curtain is opened and closed.

As shown in fig. 2 and 3, as an embodiment, each of the folding units 111 is provided with a convex ring portion 112, and the convex ring portion 112 is located on one side of the folding unit 111 where the two blind units 1 are close to each other, and the pull rope 12 passes through the convex ring portions 112 on the plurality of folding units 111 at the same time, so that the connection between the pull rope 12 and the plurality of folding units 111 in the blind 11 is achieved. Meanwhile, the pull rope 12 is positioned between the two blind curtains 11 of the two blind units 1, so that the effect of hiding the pull rope 12 is achieved, and the attractiveness of the honeycomb curtain is improved.

Specifically, the existing blind is generally perforated on each folding unit 111, and then the pull rope 12 is passed through the holes on each folding unit 111, so as to connect the pull rope 12 with each folding unit 111; but the mode not only increases the manufacturing steps and reduces the production efficiency, but also the holes on the curtain cloth can influence the light shielding performance and the beautiful appearance of the curtain cloth. In the embodiment, the convex ring parts 112 for the pull ropes 12 to pass through are arranged on each folding unit 111 of the hundred-fold curtain cloth 11, so that the curtain cloth does not need to be perforated, the manufacturing process is simplified, the production efficiency is improved, and the light-shielding property and the attractiveness of the curtain cloth are improved; moreover, as shown in fig. 2, the pull ropes 12 of the two pleated cover units 1 can be closer together, so that the pleated cover 11 of the two pleated cover units 1 can be more symmetrically fit.

Of course, in other embodiments, the cord 12 may be connected to each folding unit 111 by punching the cord. As shown in fig. 5 and 6, as another embodiment, each folding unit 111 is provided with a perforation 1110, and the pull rope 12 passes through the perforations 1110 of the plurality of folding units 111 at the same time, so that the pull rope 12 is connected to each folding unit 111.

As shown in fig. 2 and 4, as an embodiment, the connecting member 2 has a ring structure, and the pull ropes 12 of the two pleated cover units 1 pass through the connecting member 2, so that the pull ropes 12 of the two pleated cover units 1 are connected together by the connecting member 2, and the connecting member 2 can be prevented from falling off from the pull ropes 12. In this embodiment, the connecting member 2 has a circular ring structure, but may have a square ring structure, a triangular ring structure, or other structures (such as clips).

Specifically, at the time of installation, the pull cord 12 passes through the connector 2 while passing through the collar portion 112 on each folding unit 111, thereby achieving connection between the pull cord 12 and the collar portion 112 and the connector 2.

In other embodiments, the two blind units 1 may be directly connected to each other by the connecting piece 2. For example, the corresponding convex ring portions 112 of the two pleated cover units 1 are connected by the connecting piece 2.

As shown in fig. 3, as an embodiment, a folded edge 111b is formed at a folded portion of each folding unit 111, and a convex ring portion 112 is provided on the folded edge 111b of each folding unit 111. By disposing the collar portion 112 on the flange 111b of the folding unit 111, the pull cord 12 is facilitated to pass through the collar portion 112, and normal folding and unfolding actions of the folding unit 111 are not affected.

As shown in fig. 3, as an embodiment, two convex ring portions 112 are provided on each folding unit 111, and the two convex ring portions 112 are provided at intervals on the folding unit 111. The two convex ring portions 112 are disposed at intervals on the folded edge 111b of the folding unit 111. Each pleated cover unit 1 includes two pull cords 12, and the two pull cords 12 respectively pass through two convex ring portions 112 on each pleated cover unit 111. The two convex ring portions 112 on each folding unit 111 are respectively arranged near the two side edges of the blind curtain cloth 11, so that the two pull ropes 12 are also respectively arranged near the two side edges of the blind curtain cloth 11.

As shown in fig. 2, as an embodiment, two blind units 1 are connected by a plurality of connection members 2, and the plurality of connection members 2 are arranged at intervals in the up-down direction.

As shown in fig. 2 and 5, as an embodiment, each of the folding units 111 has a V-shaped structure, and V-shaped grooves 111a are formed between two adjacent folding units 111, and since the two blind units 1 are symmetrically arranged, the corresponding V-shaped grooves 111a on the two blind units 1 are also symmetrically arranged, thereby forming a honeycomb structure. The connecting piece 2 is arranged corresponding to the V-shaped groove 111a (the connecting piece 2 is positioned between two convex ring parts 112 which are adjacent up and down); when the body of the honeycomb curtain is folded (i.e. the blind curtain 11 is folded), the connecting pieces 2 can be accommodated in the V-shaped grooves 111a (as shown in fig. 5, especially when the connecting pieces 2 are large in size, the opposite ends of the connecting pieces 2 can be obviously accommodated in the V-shaped grooves 111a on two sides), so that interference between the connecting pieces 2 and the blind curtain 11 is avoided to influence normal folding and unfolding functions of the honeycomb curtain.

As shown in fig. 9 and 10, as an embodiment, the pleated cover 11 is woven by a plurality of threads 110 (i.e., the pleated cover 11 is a woven fabric), the raised ring portion 112 and the threads 110 are integrally formed (i.e., the raised ring portion 112 is a part of the threads 110 (i.e., the raised ring portion 112 and the pleated cover 11 are integrally formed), and part of the raised ring portion 112 is formed by bending and protruding a part of the threads 110 from the surface of the pleated cover 11. The pleated cover 11 may be a woven fabric knitted by a plain weave, a twill weave, a satin weave, or the like.

As shown in fig. 9 and 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 pleated cover 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 a part of the positions of the warp 1101 or the weft 1102 from the surface of the pleated cover 11.

As shown in fig. 9 and 10, in a preferred embodiment, the convex ring portion 112 is formed by bending and protruding a part of the warp 1101 from the surface of the pleated cover 11. Of course, in other embodiments, the convex ring portion 112 may be formed by bending and protruding from the surface of the pleated cover 11 for part of the positions of the weft 1102; alternatively, the convex ring portion 112 is formed by bending and protruding part of the positions of the warp 1101 and the weft 1102 from the surface of the pleated cover 11.

Specifically, the raised ring portion 112 on the pleated cover 11 may use hooks or other tools to hook the wires 110 in the pleated cover 11, so that part of the positions of the wires 110 protrude from the surface of the pleated cover 11, thereby forming the raised ring portion 112. As shown in fig. 7 to 10, when the convex ring portion 112 is not formed on the pleated cover 11, the surface of the pleated cover 11 is flat, and the wires 110 in the pleated cover 11 do not protrude from the surface of the pleated cover 11; as shown in fig. 9 and 10, when the convex ring portion 112 is formed on the pleated cover 11, the warp 1101 in the pleated cover 11 may be hooked by a hook or other tool, so that part of the warp 1101 is bent and protrudes out of the surface of the pleated cover 11, thereby forming the convex ring portion 112 on the pleated cover 11, and the pull cord 12 may pass through the convex ring portion 112 (of course, in other embodiments, the weft 1102 in the pleated cover 11 may be hooked by a hook or other tool to form the convex ring portion 112, or both the warp 1101 and the weft 1102 in the pleated cover 11 may be hooked to form the convex ring portion 112). The manufacturing method is simple in process, the hundred-fold curtain cloth 11 does not need to be perforated, structural members are not required to be additionally arranged on the hundred-fold curtain cloth 11, the structure of the hundred-fold curtain cloth 11 is not damaged, the manufacturing process is simplified, and the light-shielding performance and the attractiveness of the curtain cloth are improved.

As another embodiment, the convex ring portion 112 and the blind curtain 11 may be in a split structure (i.e., the convex ring portion 112 and the blind curtain 11 are two separate components), and the surfaces of the convex ring portion 112 and the blind curtain 11 are fixed by adhesion. In the manufacture, the wires (of course, the convex ring portion 112 may be made of other materials) may be adhered to the surface of the pleated cover 11, thereby forming the convex ring portion 112.

As shown in fig. 1, 11 and 12, as an embodiment, the honeycomb curtain further includes a curtain rod 3, the shutter curtain 11 is connected to the curtain rod 3, and the curtain rod 3 is provided with a damping member 4, where the damping member 4 is fixed to the curtain rod 3. The damping piece 4 is provided with a through hole 40, and the through hole 40 penetrates through the damping piece 4; the pull cord 12 passes through the through hole 40, and the pull cord 12 contacts with the inner wall of the through hole 40. The pull rope 12 can move relative to the damping piece 4 under the action of external pulling force and is fixed with the damping piece 4 under the action of friction force after the external pulling force is lost (contact friction force exists between the pull rope 12 and the damping piece 4 because the pull rope 12 is contacted with the inner wall of the through hole 40, the pull rope 12 is fixed with the damping piece 4 when the external pulling force is smaller than the contact friction force, and the pull rope 12 can move relative to the damping piece 4 when the external pulling force is larger than the contact friction force).

Specifically, in this embodiment, by providing the damping member 4 on the curtain rod 3 and providing the through hole 40 on the damping member 4, the pull rope 12 passes through the through hole 40, and the pull rope 12 contacts with the inner wall of the through hole 40, so that the pull rope 12 can be fixed with the damping member 4 under the action of friction force, and the pull rope 12 can move relative to the damping member 4 in the through hole 40 when receiving external tension force, thereby realizing the relative movement and locking function between the pull rope 12 and the damping member 4. The damping mechanism is simple in structure, convenient to assemble, stable and reliable in structure, stable and beneficial to prolonging the service life of the honeycomb curtain, and not only reduces the production cost, simplifies the production flow and improves the production efficiency, but also can be conveniently replaced after the damping piece 4 is damaged (only the damping piece 4 is required to be detached and replaced).

As an embodiment, the hole diameter of the through hole 40 is smaller (slightly smaller) than the outer diameter of the pull string 12, and the outer wall of the pull string 12 can be fixed in contact with the inner wall of the through hole 40 by pressing. Specifically, since the aperture of the through hole 40 is smaller than the outer diameter of the pull rope 12, when the pull rope 12 is mounted in the through hole 40 on the damping member 4, a pressing force is generated between the outer wall of the pull rope 12 and the inner wall of the through hole 40, so that a contact friction force is generated between the outer wall of the pull rope 12 and the inner wall of the through hole 40, and the pull rope 12 does not generate relative movement with the damping member 4 when not subjected to the external force. Meanwhile, the pull rope 12 is generally made of a flexible material, so that the portion of the pull rope 12 located in the through hole 40 is deformed under the action of the extrusion force, so that the pull rope 12 can be better attached to the inner wall of the through hole 40, and a more stable contact friction force is generated.

As an embodiment, the pull ropes 12 of the two pleated cover units 1 may pass through the same damping member 4 (for example, the two pull ropes 12 corresponding to the two pleated cover units 1 pass through the same through hole 40 on the damping member 4, or two through holes 40 are provided on each damping member 4, and the two pull ropes 12 corresponding to the two pleated cover units 1 respectively pass through the two through holes 40 on the damping member 4), or may respectively pass through different damping members 4.

As shown in fig. 11 and 12, the damper 4 includes a fixing block 41 as an embodiment, and the fixing block 41 is provided on the curtain rod 3 and fixed to the curtain rod 3. The through hole 40 is arranged on the fixed block 41, the through hole 40 penetrates through the fixed block 41, and the pull rope 12 penetrates through the through hole 40 on the fixed block 41. The pull cord 12 can move relative to the fixing block 41 under the action of external pulling force in the through hole 40, and is fixed with the fixing block 41 under the action of friction force after losing the action of external pulling force.

As an embodiment, the fixing block 41 is made of an elastic material, such as soft rubber (soft plastic), soft silica gel, soft rubber, or the like. By the arrangement, when the pull rope 12 is pulled, the fixed block 41 can deform to a certain extent (micro deformation), so that rigid friction between the fixed block 41 and the pull rope 12 is avoided, abrasion of the fixed block 41 and the pull rope 12 is reduced, and the service lives of the fixed block 41 and the pull rope 12 are prolonged. Of course, in other embodiments, the fixing block 41 may be made of a hard material, such as hard plastic, metal, etc.

As another embodiment, the fixing block 41 is made of a wear-resistant material, such as a wear-resistant metal material (e.g., wear-resistant steel, wear-resistant cast iron, etc.), a wear-resistant plastic material, a wear-resistant rubber material, or a wear-resistant ceramic material. This arrangement also can extend the service life of the fixing block 41.

As shown in fig. 13 to 15, as another embodiment, the damper 4 includes a fixing block 41 and a wear-resistant sleeve 42 of a cylindrical structure, and the fixing block 41 is provided on the curtain rod 3 and fixed to the curtain rod 3. The fixed block 41 is provided with a perforation 411, the perforation 411 penetrates through the fixed block 41, the wear-resistant sleeve 42 is arranged in the perforation 411 of the fixed block 41, and the wear-resistant sleeve 42 is fixed with the fixed block 41. The through hole 40 is arranged on the wear-resistant sleeve 42, the through hole 40 penetrates through the wear-resistant sleeve 42, and the pull rope 12 penetrates through the through hole 40 on the wear-resistant sleeve 42. The pull cord 12 is capable of moving relative to the wear sleeve 42 in the through bore 40 when subjected to an external pulling force and is secured to the wear sleeve 42 under friction after the external pulling force is lost.

Specifically, by arranging the wear-resistant sleeve 42 in the fixed block 41, the wear-resistant sleeve 42 is utilized to contact and rub the pull rope 12, namely, the pull rope 12 is prevented from directly contacting the fixed block 41, and the wear-resistant sleeve 42 has good wear resistance, so that the service life of the damping piece 4 is prolonged.

As one embodiment, the wear sleeve 42 is made of a wear resistant material, such as a wear resistant metallic material (e.g., wear resistant steel, wear resistant cast iron, etc.), a wear resistant ceramic material, or the like.

As an embodiment, the wear-resistant sleeve 42 and the fixing block 41 may be fixedly connected by glue, or may 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, or the like.

As shown in fig. 11 and 12, as an embodiment, the curtain rod 3 is provided with an installation groove 30, and the fixing block 41 is engaged with the installation groove 30. The mounting groove 30 extends along the length direction of the curtain rod 3, an opening 300 communicated with the mounting groove 30 is formed in the end portion of the curtain rod 3, and the opening 300 is used for allowing the fixing block 41 to pass through and then slide into the mounting groove 30.

Specifically, when the fixing block 41 is mounted, the fixing block 41 is only required to slide into the mounting groove 30 from the opening 300, and then the fixing block 41 is slid in the mounting groove 30 to a required mounting position, so that the mounting is convenient, and the fixing block 41 cannot easily fall off from the mounting groove 30.

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

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

Specifically, as shown in fig. 11 and 12, in the present embodiment, the fixing member 5 is a screw; the fixing block 41 is provided with screw holes 412, the fixing piece 5 is positioned outside the curtain rod 3, and after the fixing piece 5 passes through the curtain rod 3 (the curtain rod 3 is provided with hole sites for the fixing piece 5 to pass through), the fixing piece 5 stretches into the curtain rod 3 and is connected with the screw holes 412 on the fixing block 41, so that the fixing block 41 is further fixed and limited. Of course, in other embodiments, the fixing member 5 may be other devices, such as a spring, a pin, etc.

As shown in fig. 11 and 12, as an embodiment, one end of the pull cord 12 is located outside the curtain rod 3, and the other end of the pull cord 12 passes through the curtain rod 3 (a hole for the pull cord 12 to pass through is provided in the curtain rod 3) and then extends into the curtain rod 3, and passes through the through hole 40 in the damper 4 and then passes out of the curtain rod 3.

As shown in fig. 1 and 11, as an embodiment, two damper members 4 are provided on the curtain rod 3, the two damper members 4 are provided on the curtain rod 3 at intervals in the longitudinal direction thereof, and the pull ropes 12 are respectively provided on the two damper members 4 in a penetrating manner.

As shown in fig. 1, as an embodiment, the number of the curtain rods 3 is two, namely an upper curtain rod and a lower curtain rod (not shown), which are arranged at intervals up and down, and the upper curtain rod is located above the lower curtain rod. The shutter curtain cloth 11 is positioned between the upper curtain rod and the lower curtain rod, the top ends of the shutter curtain cloth 11 of the two shutter curtain units 1 are simultaneously connected with the upper curtain rod, the bottom ends of the shutter curtain cloth 11 of the two shutter curtain units 1 are simultaneously connected with the lower curtain rod, damping pieces 4 are arranged on the upper curtain rod and the lower curtain rod, and the upper end and the lower end of the pull rope 12 respectively penetrate through the damping pieces 4 on the upper curtain rod and the damping pieces 4 on the lower curtain rod. Of course, in other embodiments, the damping member 4 may be provided only on one of the upper and lower curtain rods.

In particular, the upper curtain rod is generally fixed to the wall. When the honeycomb curtain is required to be folded upwards, the upper end of the pull rope 12 is only required to be pulled (namely, the pull rope 12 extends to one end of the upper curtain rod), at the moment, the lower curtain rod moves upwards under the pulling action of the pull rope 12 (relative movement between the lower curtain rod and the pull rope 12 cannot be generated), meanwhile, the lower curtain rod pushes all the folding units 111 of the pleated curtain 11 to perform folding action, so that the pleated curtain 11 is folded upwards (or the lower end of the pull rope 12 is pulled by one hand (namely, the pull rope 12 extends to one end of the lower curtain rod), and then the lower curtain rod is pushed by the other hand to move upwards, so that the lower curtain rod pushes all the folding units 111 of the pleated curtain 11 to perform folding action, and the pleated curtain 11 is folded upwards); when the cellular shade is retracted upwardly to the desired position, the lower shade bar is locked in the secured position by releasing the pull cord 12, and the cellular shade is positioned in the desired position. When the honeycomb curtain needs to be hung downwards, only the lower end of the pull rope 12 is required to be pulled downwards (or the lower curtain rod is pushed by hands to move downwards), and at the moment, the lower curtain rod drives each folding unit 111 to perform unfolding action, so that the blind curtain 11 is unfolded, and the up-and-down retraction of the honeycomb curtain is realized.

The honeycomb curtain provided by the embodiment of the invention comprises two symmetrically arranged blind units 1, wherein the blind units 1 are equivalent to the existing blind, and after the two blind units 1 are connected, the blind units 11 of the two blind units 1 can jointly form a honeycomb structure, namely, the blind units 11 of the two blind units 1 jointly form a curtain body of the honeycomb curtain. The invention creatively uses two hundred-fold curtains to be connected with each other to form the curtain body of the honeycomb curtain, and uses the connecting piece 2 to connect the two curtains together, without the traditional cementing process (the hundred-fold curtains only need to be folded), thereby greatly simplifying the manufacturing process flow, improving the production and manufacturing efficiency, and improving the service life of the honeycomb curtain.

The foregoing is merely illustrative embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present invention, and the invention should be covered. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
