Description

Technical Field

[0001] The utility model relates to the technology of cloth curtain field, in particular to a cloth body connection structure and a rolling curtain. Background Art

[0002] The cloth curtain can be used as a sunshade. When it is a sunshade, such as when the user is taking a nap, it can prevent sunlight from shining into the house to avoid affecting the user's daily life.

[0003] When used as a windproof curtain, in order to prevent the curtain from being blown up by airflow, it is generally used in conjunction with a track, and the track is used to limit the curtain from being blown up.

[0004] When the curtain is used in conjunction with a track, the curtain inside the track cannot be effectively limited due to the difference in thickness. For this reason, limiting parts are generally required on both sides of the curtain to connect with the track to prevent the curtain from separating from the track.

[0005] However, the curtain is suspended in the air through the sleeve rod body. When the curtain is rolled up, the limiter is easy to affect the rolling of the curtain, which is more likely to cause the volume of the roller after the curtain is rolled up to be large, and thus a larger storage space is required to ensure that the curtain can be rolled up smoothly. Utility Model Content

[0006] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a cloth connecting structure and a roller blind. By using a limiter in the shape of a flexible sheet, the cloth blind can be easily rolled up and the volume of the roller after the cloth blind is rolled up can be reduced.

[0007] To achieve the above objectives, the utility model adopts the following technical solution: a cloth connecting structure and a roller blind, comprising a flexible sheet, a connecting piece and a cloth, wherein one end of the connecting piece is connected to the flexible sheet, and the other end is connected to the cloth.

[0008] Furthermore, the connecting piece has a first connecting portion connected to the flexible sheet, and the sum of the thickness of the first connecting portion and the flexible sheet is less than 1 mm.

[0009] Furthermore, the first connecting portion wraps around the flexible sheet.

[0010] Furthermore, the first connecting portion is a planar structure, and the first connecting portion is welded to a corresponding end surface of the flexible sheet.

[0011] Furthermore, the connecting member has a second connecting portion connected to the cloth body, and the second connecting portion extends out of the track.

[0012] Furthermore, the connecting member is fixed by welding with the flexible sheet through an adhesive member.

[0013] Furthermore, the connecting piece is fixed to the cloth body by welding through an adhesive.

[0014] Furthermore, the adhesive member is a hot melt adhesive strip, or glue, or a hot melt PVC strip material; the connecting member is a cloth with hot melt adhesive.

[0015] Furthermore, the flexible sheet is a rigid sheet.

[0016] A rolling curtain has a cloth body wound with a rotating rod, the rotating rod is installed on a plane so that the cloth body is suspended in the air, and the flexible sheet material is slidably arranged in a track.

[0017] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that the flexible sheet is connected to the cloth body through a connecting piece. If the cloth body needs to be rolled up, the flexible sheet can reduce the volume of the roll after the cloth body is rolled up due to its own shape and the cooperation with the connecting piece, and reduces the occupied space, making it convenient for users to store and use it.

[0018] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please refer to Figure 1-6 As shown, it shows the specific structure of the preferred first embodiment of the utility model, which is a cloth body connection structure and a rolling curtain, including a flexible sheet 10, a connecting member 20 and a cloth body 30, one end of the connecting member 20 is connected to the flexible sheet 10, and the other end is connected to the cloth body 30. When the cloth body 30 is rolled up, the volume of the roll formed after rolling up can also be reduced, thereby further reducing the space occupied by the cloth body connection structure.

[0032] Specifically, there are no less than two tracks 40, and the two tracks 40 are correspondingly installed on the wall or plane. The left and right side edges of the cloth body 30 are respectively connected to the flexible sheet 10 through the connecting parts 20, and the flexible sheet 10 is inserted into the track 40 and slides. When the airflow blows over the cloth body 30, due to the sliding connection between the flexible sheet 10 and the track 40, the side edges or corners of the cloth body 30 will not be blown up, thereby enhancing the protective effect of the cloth body when used as a windproof curtain or a sunshade curtain. When the airflow blows over the cloth body 30, or the cloth body 30 moves up and down, because the flexible sheet 10 is in the shape of a plate, the connection part with the cloth body 30 is located in the middle of the flexible sheet 10, so that the two sides of the flexible sheet 10 can conflict with the inner wall of the track 40, so that when the cloth body 30 moves / is blown by the airflow, the flexible sheet 10 will not be easily separated from the track 40, and affect the user's use. Figure 1 As shown, the flexible sheet 10 is located in the track 40 and moves up / down along the track 40. The cloth body 30 and the connecting member 20 are in a taut state due to the connection between the flexible sheet 10 and the track 40, so as to achieve a better windproof / sunshading effect.

[0033] like Figure 2 As shown, exemplarily, the connector 20 has a first connector 21 connected to the flexible sheet 10 , the sum of the thickness of the first connector 21 and the flexible sheet 10 is less than 1 mm, and the first connector 21 wraps the flexible sheet 10 . When installing the assembly, the flexible sheet 10 is placed on the first connecting part 21, or the first connecting part 21 is fitted with one side of the flexible sheet 10, and then the first connecting part 21 is bent to form two bending surfaces, and the two bending surfaces are respectively fitted with one of the two side edges of the flexible sheet 10. Finally, the bending surface is bent again and moved to the middle of the other side of the flexible sheet 10. At this time, the first connecting part 21 completes the wrapping of the flexible sheet 10, and then the two bending surfaces are overlapped and tightened to increase the tightness of the flexible sheet 10 after wrapping. In addition, because the total thickness of the flexible sheet 10 after wrapping and the first connecting part 21 after wrapping the flexible sheet 10 is less than 1 mm, when the cloth body 30 is rolled up, the rolled cloth body 30 is smaller in size and occupies less space than the reel that uses objects such as ropes and rubber ropes as sliding parts and is rolled up with the cloth body 30, and is more convenient for users to use.

[0034] Exemplarily, the connector 20 has a second connecting portion 22 connected to the cloth body 30, and the second connecting portion 22 extends out of the track 40. The second connecting portion 22 is the portion after the two bending surfaces in the first connecting portion 21 overlap, and the second connecting portion 22 is connected to the cloth body 30. The connecting portion between the cloth body 30 and the second connecting portion 22 can be located on both sides of the second connecting portion 22, or can be located between the overlapping portions of the two bending surfaces. It should be noted that the position of the cloth body 30 corresponds to the middle of one side of the flexible sheet 10 to ensure that the cloth body 30 is horizontal after the flexible sheet 10 is slidably connected to the track 40. Improve the overall stability when the user rolls up the cloth body 30.

[0035] like Figure 2 As shown, for example, the connector 20 is bonded and fixed to the flexible sheet 10 by an adhesive 50, and the adhesive 50 can be a hot-melt adhesive strip, or glue, or a PVC strip or other hot-melt material. After the first connector 21 is sleeved with the flexible sheet 10, in order to prevent the flexible sheet 10 from separating from the connector 20, the adhesive 50 can be coated or placed on the fitting surface of the first connector 21 and the flexible sheet 10, and the first connector 21 and the flexible sheet 10 are connected together by its viscosity / hot pressing / melting during hot air blowing. Although this method can prevent the flexible sheet 10 from slipping out of the first connector 21 when the cloth body 30 is suspended in the air. However, after the first connector 21 wraps the flexible sheet 10, the two overlapping surfaces of the first connector 21 may not be aligned, thereby affecting the appearance of the product.

[0036] Exemplarily, the adhesive 50 can also be located between the two overlapping surfaces of the first connecting part 21, that is, in the second connecting part 22. When the adhesive 50 is located in the second connecting part 22, the cloth body 30 can be inserted therein and connect the connecting part 20 and the cloth body 30 together, and the flexible sheet 10 is tightly fitted to the first connecting part 21 to form a limit. Since the flexible sheet 10 is not in direct contact with the adhesive 50, space for adjustment of the first connecting part 21 can be provided to facilitate production personnel to align the two overlapping surfaces of the first connecting part 21.

[0037] Exemplarily, the connector 20 is bonded and fixed to the cloth body 30 by means of an adhesive 50. The cloth body 30 can also be bonded and fixed to the side of the second connecting portion 22 by means of an adhesive 50. Compared with the cloth body 30 being located inside the second connecting portion 22, the cloth body 30 located on the outer wall of the second connecting portion 22 will not generate contact friction with the inner wall of the track 40 due to the offset of the position of the second connecting portion 22, so as to avoid the surface of the cloth body 30 being worn and affecting the beauty of the cloth body 30.

[0038] It should be noted that the flexible sheet 10 is a steel sheet. The flexible sheet 10 has a certain flexibility and a certain strength to prevent the flexible sheet 10 from falling off when sliding in the track 40 .

[0039] Embodiment 1

[0040] Based on the function and structure of the above-mentioned cloth body connection structure, Figure 3-4 As shown, in the first embodiment, the flexible sheet 10 is connected via the first connecting portion 21 .

[0041] In the first embodiment, the first connection portion 21 is a planar structure, and the first connection portion 21 is welded to the corresponding end surface of the flexible sheet 10 .

[0042] Specifically, the first connection part 21 is changed from wrapping the flexible sheet 10 in the previous embodiment to being attached to one side of the flexible sheet 10. When the flexible sheet 10 and the first connection part 21 are assembled and installed, compared with the previous embodiment, in which the first connection part 21 needs to wrap the flexible sheet 10 and the connection between the first connection part 21 and the second connection part 22 needs to correspond to the middle of one side of the flexible sheet 10, in this first embodiment, the first connection part 21 is a layer of plate / cloth, and the plate / cloth only needs to be aligned with one side of the flexible sheet 10, which is faster in processing and production than the previous example.

[0043] Exemplarily, the connecting member 20 is bonded and fixed to the flexible sheet 10 by an adhesive member 50 .

[0044] Specifically, the adhesive member 50 is located at the bonding surface between the first connection portion 21 and the flexible sheet 10 . The adhesive member 50 is preferably a hot melt adhesive strip. Since the hot melt adhesive strip has a certain anti-stretching effect, it can effectively prevent the first connection portion 21 and the flexible sheet 10 from separating.

[0045] Embodiment 2

[0046] Based on the function and structure of the above-mentioned cloth body connection structure, Figure 5 As shown, in the second embodiment, the connecting member 20 can be a hot melt adhesive strip, or glue, or a hot melt PVC strip material. Compared with the above two embodiments, in this embodiment, the connecting member 20 is changed to a hot melt adhesive strip, and the cloth body 30 can be directly connected to the flexible sheet 10 through the hot melt adhesive strip. By reducing the connection structure between the cloth body 30 and the flexible sheet 10, the manufacturing cost is reduced, the manufacturing process is accelerated, and after the cloth body 30 is rolled up, the volume of the cloth body 30 after rolling up can still be reduced.

[0047] Embodiment 3

[0048] This embodiment is to utilize the function and structure of the above-mentioned cloth body connection structure in an application in a rolling curtain, such as Figure 6 As shown, in the third embodiment, the cloth body 30 is wound around the rotating rod 60, and the cloth body 30 is rolled up / loosened as the rotating rod 60 rotates forward / reverse.

[0049] Exemplarily, a rolling blind, a cloth body 30 is wound with a rotating rod 60, and the rotating rod 60 is installed on a plane so that the cloth body 30 is suspended in the air. When the cloth body 30 rotates with the rotating rod 60 to be rolled up, at least one side of the cloth body 30 is connected to the flexible sheet 10 through a connecting member 20. At this time, when the cloth body 30 rotates with the rotating rod 60 to be rolled up, the flexible sheet 10 is located in the middle of one side because the connection with the flexible sheet 10 is located. The flexible sheet 10 is tilted under the pressure of the cloth body 30 during rolling up, and is wrapped between the reels of the rolled cloth body 30. Compared with the existing rolling blinds that use ropes or rubber ropes or other objects as sliding blocks of the track 40, the volume of this rolling blind after rolling up is smaller, the space required is less, and it is more convenient for users to use. Compared with the traditional cloth body connection structure, the sliding part sliding in the track 40 is larger in volume. The cloth body connection structure reduces the volume of the sliding part, so that the track 40 occupies less space.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
