Description

Technical Field

[0001] This utility model belongs to the field of curtain technology, specifically relating to a curtain whose height and width can be freely adjusted. Background Technology

[0002] Curtains are an essential home decoration product for every household. Traditional curtain products on the market are highly customizable, requiring the specific dimensions of each window in the customer's home to be measured and customized according to the width and height of each window. Once made, the size is fixed and cannot be adjusted.

[0003] Currently, curtain sizes are fixed and cannot be adjusted. The sales process requires professional technicians to visit customers' homes to measure dimensions, resulting in significant communication, labor, and time costs. The highly customized nature of curtains increases production costs and extends the production cycle, preventing standardization, mass production, and large-scale manufacturing. Each curtain is custom-made to the dimensions of every window in each customer's home. Once completed, each curtain's size is fixed and cannot be adjusted. Any size deviations during measurement or production cannot be addressed in after-sales service, necessitating remaking. Furthermore, curtains cannot be reused; customers must purchase new ones when moving or changing houses.

[0004] A search revealed that CN220327268U discloses a curtain with adjustable height and width, comprising a first curtain body and a second curtain body. The back of the first curtain body is fixedly connected to multiple rows of equally spaced upper zippers, and the top of the second curtain body is fixedly connected to a row of lower zippers. Because curtains are highly customizable, their manufacturing requires individual customization based on the dimensions of each customer's window, making standardization, prefabrication, and mass production impossible. This utility model patent, allowing for adjustable width and height, achieves standardization, prefabrication, and mass production of curtains, saving time and labor costs. This represents a significant change in the curtain industry model. However, its drawback lies in the fact that the zippers used for adjustment of the first and second curtains are cumbersome to connect in actual use, and the zippers are prone to deformation under pressure, affecting overall usability. Therefore, designing a curtain with adjustable height and width to address these shortcomings is crucial. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a curtain with freely adjustable height and width. This first and second curtain solves the problem in the prior art where the curtain is fixed by a zipper. In actual use, the zipper connection is relatively troublesome, and the zipper is deformed when squeezed, which affects the overall use.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a curtain with freely adjustable height and width, which includes a first curtain and a second curtain; the second curtain is located at the bottom of the first curtain, and a connecting component is provided at the top of the second curtain;

[0009] The connecting assembly is used to connect the second curtain to the first curtain. The connecting assembly includes multiple sets of fixed tubes fixedly connected to the top of the second curtain. The inside of the fixed tube is provided with a receiving groove. Both ends of the receiving groove are slidably connected to limit blocks. A moving rod is fixedly connected to the end of the limit block away from the receiving groove. A compression spring is sleeved on the outside of the moving rod and inside the fixed tube.

[0010] When using the first and second curtains of this technical solution, select a row of connecting posts according to the overall height of the curtains, and connect the fixing cylinder to the corresponding connecting posts. When the fixing cylinder is connected to the connecting posts, the fixing block is displaced into the receiving groove. The compression spring drives the limiting block to move to the bottom of the fixing block, limiting the fixing block inside the receiving groove, thereby limiting the connection between the fixing cylinder and the connecting posts for the installation of the second curtain. When the second curtain is connected to the first curtain, the Velcro surface can be connected to the corresponding Velcro hook surface, increasing the stability of the connection between the second curtain and the first curtain and preventing loosening. When the first and second curtains are connected, the counterweight strip makes the blind curtain vertically downward. The blind curtain can cover the connection between the first and second curtains, thereby increasing the overall aesthetics.

[0011] Preferably, the limiting block is designed with an inverted trapezoidal structure, the moving rod and the fixed cylinder are slidably connected, and the two ends of the compression spring are fixedly connected to the fixed cylinder and the limiting block, respectively.

[0012] Furthermore, multiple sets of connecting posts are fixedly connected to the outer side of the first curtain, and these multiple sets of connecting posts are arranged in four rows on the outer side of the first curtain.

[0013] Furthermore, a fixing block is fixedly connected to the front end of the connecting column, and a guide block is slidably connected to the rear end of the connecting column. The contact surfaces of the fixing block and the guide block form an arc-shaped surface, and both ends of the fixing block and the guide block are designed with a planar structure.

[0014] Furthermore, the fixing block and guide block are slidably connected to the receiving groove, and multiple sets of fixing cylinders are distributed at equal intervals on the outside of the second curtain.

[0015] Furthermore, the outer side of the first curtain and below each column of connecting posts is fixedly connected with a hook and loop fastener, and the end of the second curtain near the first curtain is fixedly connected with a hook and loop fastener, with the hook and loop fastener and hook and loop fastener connected to each other.

[0016] Furthermore, a blind curtain is fixedly connected to the top of the first curtain, and a counterweight strip is fixedly connected to the bottom of the blind curtain.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The first and second curtains of this utility model are designed with a connecting component. When the second curtain needs to be installed on the first curtain, the fixing cylinder is aligned with the connecting post at the selected height position. The connecting posts are arranged in multiple rows corresponding to different heights. The fixing block and guide block inside the fixing cylinder enter the receiving groove, pushing the limiting block to move inward and compressing the spring. When the fixing block is fully in the receiving groove, the compressed spring rebounds, pushing the limiting block to move outward and lock under the fixing block, achieving mechanical locking. Pressing the fixing cylinder causes the guide block to enter the receiving groove again, pushing the limiting block to move inward. At this time, pulling the fixing cylinder outward causes the limiting block to slide outward along the arc surface of the guide block and the fixing block, finally disengaging from the locked state and achieving quick disassembly. By selecting connecting post rows of different heights, the second curtain and the first curtain can be connected at multiple heights, thereby adjusting the overall curtain height. The mechanical locking method using springs and limiting blocks eliminates the need for easily damaged parts such as zippers, making installation and disassembly more convenient and quick. Compared with zippers, the mechanical structure is more resistant to compression and pulling, has a longer service life, and is less likely to be affected by deformation. Attached Figure Description

[0027] This specific embodiment is a curtain whose height and width can be freely adjusted, and its structural diagram is shown below. Figure 1-6 As shown, the curtain includes a first curtain 1 and a second curtain 2; the second curtain 2 is located at the bottom of the first curtain 1, and a connecting component 3 is provided at the top of the second curtain 2;

[0028] The connecting component 3 is used to connect the second curtain 2 to the first curtain 1. The connecting component 3 includes multiple sets of fixing cylinders 4 fixedly connected to the top of the second curtain 2. The inside of the fixing cylinder 4 is provided with a receiving groove 5. Both ends of the receiving groove 5 are slidably connected to limit blocks 6. The end of the limit block 6 away from the receiving groove 5 is fixedly connected to a moving rod 7. A compression spring 8 is sleeved on the outside of the moving rod 7 and inside the fixing cylinder 4.

[0029] In this embodiment, the limiting block 6 is designed with an inverted trapezoidal structure, the moving rod 7 is slidably connected to the fixed cylinder 4, and the two ends of the compression spring 8 are fixedly connected to the fixed cylinder 4 and the limiting block 6 respectively. The moving rod 7 is slidably connected to the fixed cylinder 4. When the limiting block 6 is displaced, the moving rod 7 can guide it, so that the limiting block 6 can be displaced stably. The compression spring 8, in conjunction with the fixed cylinder 4, can drive the limiting block 6 to move.

[0030] Secondly, in this embodiment, multiple sets of connecting posts 9 are fixedly connected to the outside of the first curtain 1. The multiple sets of connecting posts 9 are arranged in four columns on the outside of the first curtain 1. When the second curtain 2 is connected to the first curtain 1, a column of connecting posts 9 is selected according to the overall height of the curtain, and the fixing cylinder 4 is connected to the corresponding connecting post 9.

[0031] In addition, in this embodiment, a fixing block 10 is fixedly connected to the front end of the connecting post 9, and a guide block 11 is slidably connected to the rear end of the connecting post 9. The contact surfaces of the fixing block 10 and the guide block 11 form an arc-shaped surface. Both ends of the fixing block 10 and the guide block 11 are designed with a planar structure. The fixing block 10 and the guide block 11 are slidably connected to the receiving groove 5. Multiple sets of fixing cylinders 4 are evenly distributed on the outside of the second curtain 2. When the fixing cylinder 4 is connected to the connecting post 9, the fixing block 10 is displaced to the inside of the receiving groove 5. The compression spring 8 drives the limiting block 6 to move, so that the limiting block 6 moves to the bottom of the fixing block 10, limiting the fixing block 10 inside the receiving groove 5, thereby limiting the connection between the fixing cylinder 4 and the connecting post 9, and installing the second curtain 2.

[0032] Furthermore, in this embodiment, a hook face 12 is fixedly connected to the outer side of the first curtain 1 and below each column of connecting posts 9. A hook face 13 is fixedly connected to the end of the second curtain 2 near the first curtain 1. The hook face 13 and the hook face 12 are connected to each other. When the second curtain 2 is connected to the first curtain 1, the hook face 13 can be connected to the corresponding hook face 12, which increases the stability of the connection between the second curtain 2 and the first curtain 1 and prevents loosening.

[0033] Furthermore, in this embodiment, a blind curtain 14 is fixedly connected to the top of the first curtain 1, and a counterweight strip is fixedly connected to the bottom of the blind curtain 14. When the first curtain 1 and the second curtain 2 are connected, the counterweight strip makes the blind curtain 14 vertically downward. The blind curtain 14 can cover the connection between the first curtain 1 and the second curtain 2, thereby increasing the overall aesthetics.

[0034] When using the device of this technical solution, when the second curtain 2 is connected to the first curtain 1, a row of connecting posts 9 is selected according to the overall height of the curtains. The fixing cylinder 4 is connected to the corresponding connecting post 9. When the fixing cylinder 4 is connected to the connecting post 9, the fixing block 10 is displaced into the receiving groove 5. The compression spring 8 drives the limiting block 6 to move, so that the limiting block 6 moves to the bottom of the fixing block 10, limiting the fixing block 10 inside the receiving groove 5. Thus, the fixing cylinder 4 and the connecting post 9 are connected and the second curtain 2 is installed. When the second curtain 2 is connected to the first curtain 1, the Velcro surface 13 can be connected to the corresponding Velcro hook surface 12, increasing the stability of the connection between the second curtain 2 and the first curtain 1 and preventing loosening. When the first curtain 1 and the second curtain 2 are connected, the counterweight makes the blind curtain 14 vertically downward. The blind curtain 14 can control the first curtain 1 and the second curtain. The connection point of curtain 2 is covered to enhance the overall aesthetics. When the second curtain 2 needs to be disassembled, press the fixing cylinder 4 to move it towards the connecting post 9, causing the guide block 11 to move into the receiving groove 5. The limiting block 6 contacts the guide block 11, and the compression spring 8 drives the limiting block 6 to move. The limiting block 6 contacts the bottom of the guide block 11, and the fixing cylinder 4 is moved away from the connecting post 9. This causes the limiting block 6 to drive the guide block 11 to move, bringing the guide block 11 into contact with the fixing block 10. The surfaces of the two form an arc, allowing the limiting block 6 to move out from the outside of the guide block 11 and the fixing block 10. This disconnects the lock between the fixing cylinder 4 and the connecting post 9, allowing the second curtain 2 to be disassembled. The second curtain 2 can then be reinstalled according to the required overall height. Compared with existing curtains, this invention improves the overall practicality of the curtain through its design.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
