Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a longitudinally retractable curtain with edges that are not easily deformed. Background Art

[0002] Curtains are an important part of home decoration. According to the classification of the retracting method, they include horizontal retractable curtains and vertical retractable curtains. With the development of intelligent life, electric curtains have gradually entered the public eye. On the basis of traditional horizontal and vertical retractable curtains, one button can often realize automatic retraction of the curtain body, and the convenience of use is significantly improved. However, it is still in the early stages of development, so there are some problems. Taking the vertical retractable curtains as an example, chains are symmetrically arranged on both sides of the curtain body, and limiting structures are symmetrically arranged at both ends of the reel, and the chains are slidably connected to the limiting structures. Although this can ensure the stability of the retracting process, the chains and the curtain body are generally directly welded by ultrasonic welding, which leads to a significant increase in the thickness of the welding position. In addition, the curtain body and the chain are not soft fabrics, but chemicals after comprehensive consideration of factors such as hardness, toughness, and flatness. Therefore, the retracting process is particularly prone to wrinkling of the welding position, which in turn affects the aesthetics of the curtain body and even increases the possibility of damage to the wrinkled position. Based on this situation, how to avoid the situation where the welding positions on both sides of the vertical retractable curtains are too thick and wrinkled during use is becoming an increasingly urgent problem that relevant technical personnel need to solve. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a longitudinally retractable curtain whose edge is not easily deformed.

[0004] A longitudinally retractable curtain with edges that are not easily deformed, comprising a curtain body, characterized in that: chain belts are symmetrically arranged on both sides of the curtain body, a cloth belt is arranged in front of the chain belt, a first connecting belt is arranged at a position corresponding to the curtain body at the rear of the cloth belt, a second connecting belt is arranged at a position corresponding to the chain belt at the rear of the cloth belt, the cloth belt is fixedly connected to the curtain body via the first connecting belt, and the cloth belt is fixedly connected to the chain belt via the second connecting belt.

[0005] Furthermore, the link belt includes an inner connecting part and an outer connecting part, the outer connecting part and the inner connecting part are an integral structure, the second connecting belt is located in front of the inner connecting part, one end of the inner connecting part away from the outer connecting part is located between the cloth belt and the curtain body, and the part of the inner connecting part located between the cloth belt and the curtain body is in contact with the curtain body.

[0006] Furthermore, the thickness of the cloth belt is smaller than the thickness of the chain belt, and the thickness of the chain belt is smaller than the thickness of the curtain body.

[0007] The beneficial effects of the longitudinally retractable curtain with edges that are not easily deformed of the utility model are as follows:

[0008] 1. The design that the cloth belt is fixedly connected to the curtain body and the chain belt through the first connecting belt and the second connecting belt respectively effectively avoids the direct connection between the chain belt and the curtain body. The design that the cloth belt thickness is less than the chain belt thickness and the chain belt thickness is less than the curtain body thickness makes it possible to make the overall thickness less than the thickness of the chain belt and the curtain body directly welded even with the introduction of the new structure of the cloth belt, thereby effectively avoiding the situation that the welding positions on both sides of the longitudinal retractable curtain are too thick and thus wrinkled during use;

[0009] 2. The design that the inner connection part is located between the cloth belt and the curtain body at one end away from the outer connection part and fits with the curtain body effectively ensures the continuity of the cloth belt, chain belt and curtain body as a whole after welding, thereby effectively ensuring the stability of the curtain body during the retraction and extension process.

[0015] To make the description clearer, a longitudinally retractable curtain with edges that are not easily deformed of the utility model is further described in conjunction with the accompanying drawings of the specification.

[0016] A longitudinally retractable curtain with edges that are not easily deformed, comprising a curtain body 3, characterized in that: chain belts 1 are symmetrically arranged on both sides of the curtain body 3, a cloth belt 2 is arranged at the front of the chain belt 1, a first connecting belt 4 is arranged at the rear of the cloth belt 2 corresponding to the curtain body 3, a second connecting belt 5 is arranged at the rear of the cloth belt 2 corresponding to the chain belt 1, the cloth belt 2 is fixedly connected to the curtain body 3 via the first connecting belt 4, and the cloth belt 2 is fixedly connected to the chain belt 1 via the second connecting belt 5.

[0017] Furthermore, the chain belt 1 includes an inner connecting part 7 and an outer connecting part 6, the outer connecting part 6 and the inner connecting part 7 are an integral structure, the second connecting belt 5 is located in front of the inner connecting part 7, the end of the inner connecting part 7 away from the outer connecting part 6 is located between the cloth belt 2 and the curtain body 3, and the part of the inner connecting part 7 located between the cloth belt 2 and the curtain body 3 is in contact with the curtain body 3.

[0018] Furthermore, the thickness of the cloth belt 2 is smaller than the thickness of the chain belt 1 , and the thickness of the chain belt 1 is smaller than the thickness of the curtain body 3 .

[0019] The working principle of the longitudinal retractable curtain with edges not easily deformed of the utility model is as follows: as shown in the attached drawings, the curtain body 3, the chain belt 1, and the cloth belt 2 are laid flat in the processing position in sequence, and the cloth belt 2, the curtain body 3, and the chain belt 1 are welded at the positions of the first connecting belt 4 and the second connecting belt 5 by ultrasonic welding equipment. After the welding is completed, the chain belt 1, the cloth belt 2, and the curtain body 3 become a whole, the upper part of the curtain body 3 is fixedly connected to the matching reel, the outer connecting part 6 is slidably connected to the matching limiting structure, and a draping structure is fixed at the lower part of the curtain body 3 to keep the curtain body 3 flat , the curtain can be put into use. In the default state, the curtain body 3 is in the rolled-up state. Press the relevant button to start the release command, and the reel starts to rotate. Under the sliding limit of the limiting structure on the chain belt 1 and the draping effect of the draping structure on the curtain body 3, the curtain body 3 always remains flat until it is fully unfolded. The cloth belt 2 is fixedly connected with the curtain body 3 and the chain belt 1, and the thickness of the cloth belt 2 is less than the thickness of the chain belt 1, and the thickness of the chain belt 1 is less than the thickness of the curtain body 3, so that the welding position will not be too thick, and the welding position will not be wrinkled due to its thickness even if it is repeatedly retracted and released.
