Description

Technical Field

[0001] The present application relates to the technical field of sunshade curtains, and in particular to a sunshade curtain. Background Art

[0002] Sunshade curtains are widely used in schools, hospitals, office buildings and other places because of their easy installation, simple structure and obvious sunshade effect.

[0003] Patent publication number CN104989260A discloses a wind-resistant sunshade curtain. The specification describes a side rail with two symmetrically arranged clips longitudinally inserted into its inner edge. A gap is formed between the clips, facing the side of the rolling curtain fabric. The upper end of the gap is connected to the window cover. The two edges of the rolling curtain fabric extend through the longitudinal opening of the side rail and the gap between the clips, respectively, and then into the inner cavity of the side rail. It is conceivable that the two clips could be integrally formed, in which case the clipping element would serve as the inner rail with the gap.

[0004] In the aforementioned patent, the two sides of the rolling curtain slide within the gap. However, when the rolling curtain is initially retracted, it escapes from the gap. Furthermore, when the rolling curtain is pulled downward to unfold, due to installation errors, the two sides of the rolling curtain are easily misaligned with the gap, causing the rolling curtain to interfere with the top of the side rail, affecting the unwinding and use of the rolling curtain. Utility Model Content

[0005] In order to improve the smoothness of curtain retraction, the present application provides a sunshade curtain.

[0006] The present application provides a sunshade curtain, which adopts the following technical solution:

[0007] A sunshade curtain comprises a curtain cover, wherein a curtain is wound inside the curtain cover, vertical frames are symmetrically provided at both ends of the bottom surface of the curtain cover, two sides of the curtain respectively pass through and extend into the vertical frames, and limit strips are respectively provided on both sides of the curtain, a guide cavity is provided in the vertical frame, and a guide rail is provided in the guide cavity, and the two sides of the curtain are respectively slidably connected to the guide rails, a guide seat is provided at the top end of the guide rail, and a guide opening is opened on the top surface of the guide seat, and the two sides of the curtain are respectively slidably connected to the guide seat through the guide opening.

[0008] By adopting the above technical solution, when using the sunshade curtain, the curtain is pulled downward to be rolled out from the curtain cover. During the process of pulling the curtain downward, the two sides of the curtain are first slid and inserted into the guide seat through the guide opening, and then the curtain slides along the guide seat and is inserted into the guide rail. The curtain is finally pulled downward along the guide rail and is finally stably inserted into the guide rail through the guide opening, avoiding interference and collision between the curtain and the top of the guide rail when it is initially pulled down, which is beneficial to improve the smoothness of the curtain retraction and pulling.

[0009] Optionally, the inner wall of the guide base is provided with an insertion strip, one end of the insertion strip extends out of the guide base, the top surface of the guide rail is provided with an insertion slot, and the insertion strip is tightly inserted into the insertion slot.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] See also Figures 1-4 A sunshade curtain comprises a curtain cover 1. A curtain 2 is wound and installed inside the curtain cover 1, and one end of the curtain 2 passes through and extends outside the bottom of the curtain cover 1. The winding method of the curtain 2 is a well-known means in the art. Vertical frames 3 are symmetrically fixedly connected to both ends of the bottom surface of the curtain cover 1, and both sides of the curtain 2 extend into the vertical frames 3 respectively. Limiting strips 4 are provided on both sides of the curtain 2, and the curtain 2 is slidably connected to the vertical frames 3. A guide cavity 5 is reserved in the middle of the vertical frame 3, and a guide rail 6 is installed in the guide cavity 5. The two sides of the curtain 2 are slidably connected to the guide rails 6 on both sides respectively. A guide seat 7 is installed at the top of the guide rail 6, and a guide opening 8 is provided on the top surface of the guide seat 7. The two sides of the curtain 2 are slidably connected to the guide seat 7 on both sides through the guide opening 8.

[0032] When the sunshade curtain is to be used, the bottom end of the curtain 2 is pulled downward. After the curtain 2 is extended from the curtain cover 1, both sides of the curtain 2 are inserted into the guide seats 7 through the guide openings 8. As the curtain 2 is continuously pulled downward, both sides of the curtain 2 are slidably inserted into the guide rails 6 through the guide seats 7. The curtain 2 is then pulled out for use.

[0033] See also Figure 4 To facilitate assembly and disassembly of the guide base 7 and the guide rail 6, three inserting strips 9 are fixedly connected to the inner wall of the guide base 7, with one end of each of the three inserting strips 9 extending outside the guide base 7. Slots 10 are provided at the top of the guide rail 6 corresponding to the positions of the three inserting strips 9, and the inserting strips 9 are tightly plugged into the slots 10.

[0034] When the guide base 7 needs to be installed, the inserting strips 9 on the guide base 7 are first aligned and inserted into the slots 10 . Since the inserting strips 9 are tightly inserted into the slots 10 , the guide base 7 is fixedly connected to the guide rail 6 via the inserting strips 9 .

[0035] It is worth noting that see Figure 4 The wall of the guide opening 8 is arranged in an arc shape along the direction of the guide rail 6. Under the effect of the guide opening 8 arranged in an arc shape, it is beneficial to further improve the stability of the two sides of the curtain 2 slidingly plugged into the guide seat 7.

[0036] See also Figure 4 To prevent the curtain 2 from tearing when subjected to left-right pulling forces, multiple groups of spring clips 11 are installed in the guide cavity 5. These groups of spring clips 11 are linearly distributed along the vertical direction of the mullion 3. Each group of spring clips 11 includes two spring clips 11, which are symmetrically installed in the guide cavity 5. One side of each spring clip 11 abuts against the surface of the guide rail 6, and the other side of each spring clip 11 abuts against the inner wall of the guide cavity 5.

[0037] The spring piece 11 is bent into a semi-arc shape, and both ends of the spring piece 11 are fixedly connected to the clamping strips 12 , and the clamping strips 12 are clamped in the slot 10 .

[0038] In addition, a buffer block 13 is installed in the spring piece 11 , and the buffer block 13 is fixedly connected to the inner wall of the guide rail 6 .

[0039] When the curtain 2 is pulled left or right, the two ends of the curtain 2, respectively, drive the guide rail 6 to move left or right via the limit bars 4. At this time, the guide rail 6 squeezes the spring plate 11, which in turn cushions the squeezing force of the guide rail 6. Furthermore, when the curtain 2 is suddenly pulled left or right, the two ends of the curtain 2, respectively, drive the guide rail 6 to move instantaneously via the limit bars 4. At this time, the guide rail 6 squeezes the spring plate 11 and presses it against one side of the buffer block 13. The buffer block 13 helps prevent the guide rail 6 from colliding with the wall of the guide cavity 5 and causing damage.

[0040] See also Figure 1 and Figure 2 One end of the curtain 2 is fixedly clamped with a hanging tube 14, and both ends of the hanging tube 14 are slidably connected to the vertical frames 3 on both sides.

[0041] The vertical movement of the hanging tube 14 is guided by the vertical frames 3 on both sides, thereby improving the stability of the vertical movement of the hanging tube 14. Clamping and fixing one end of the curtain 2 by the hanging tube 14 is conducive to preventing one end of the curtain 2 from getting wet and winding.

[0042] See also Figure 3 To enhance the ease of assembly and disassembly of the mullion 3 and the stability of the guide rail 6 within the guide cavity 5, the mullion 3 includes a base plate 15, a first half-frame 16, and a second half-frame 17. The first half-frame 16 is fixed to the top surface of the base plate 15 via bolts. The first half-frame 16 and the second half-frame 17 are positioned opposite each other. A protrusion 18 and a clip 19 are fixedly connected to the side of the second half-frame 17 facing the first half-frame 16. A groove 20 and a fixing bar 21 are fixedly connected to the side of the first half-frame 16 facing the second half-frame 17. The protrusion 18 engages with the groove 20, and the fixing bar 21 snaps into the clip 19.

[0043] When assembling the mullion 3, first, bolt the first half-frame 16 to the top surface of the base plate 15. Then, pre-install the guide rail 6 in the guide cavity 5. Next, position the second half-frame 17 opposite the first half-frame 16. Then, forcefully push the second half-frame 17 toward the first half-frame 16 to engage. At this point, the protruding strips 18 engage with the grooves 20, and the fixing strips 21 engage with the clips 19. The first and second half-frames 16, 17 are securely connected.

[0044] The working principle of a sunshade curtain:

[0045] When the sunshade curtain is to be used, the bottom end of the curtain 2 is pulled downward. After the curtain 2 is extended from the curtain cover 1, both sides of the curtain 2 are inserted into the guide seats 7 through the guide openings 8. As the curtain 2 is continuously pulled downward, both sides of the curtain 2 are slidably inserted into the guide rails 6 through the guide seats 7. The curtain 2 is then pulled out for use.

[0046] When the curtain 2 is pulled left or right, the two ends of the curtain 2, respectively, drive the guide rail 6 to move left or right via the limit bars 4. At this time, the guide rail 6 squeezes the spring plate 11, which in turn cushions the squeezing force of the guide rail 6. Furthermore, when the curtain 2 is suddenly pulled left or right, the two ends of the curtain 2, respectively, drive the guide rail 6 to move instantaneously via the limit bars 4. At this time, the guide rail 6 squeezes the spring plate 11 and presses it against one side of the buffer block 13. The buffer block 13 helps prevent the guide rail 6 from colliding with the wall of the guide cavity 5 and causing damage.

[0047] In summary, the arc-shaped guide opening 8 ultimately allows the curtain 2 to be stably inserted into the guide rail 6, avoiding interference and collision between the curtain 2 and the top of the guide rail 6 when initially pulled down, thereby facilitating smoother retraction of the curtain 2.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
