Description

Technical Field

[0001] This utility model belongs to the field of sunshade curtains, and particularly relates to a highly stable sunshade curtain. Background Technology

[0002] Existing sunshades, such as the outdoor windproof sunshade roller blind with application number 201721186891.X, include a roller blind window with a drive tube at the top. One end of the drive tube is rotatably connected to the roller blind window, and the other end is connected to a tubular motor that drives the drive tube to rotate. Roller blind fabric is wound around the drive tube, and a counterweight rod is located at the bottom of the roller blind fabric. To improve wind resistance, a magnetic structure is installed between the bottom rod and the bottom of the roller blind window. When the bottom rod reaches the bottom of the roller blind window, the two establish a magnetic connection, overcoming wind force and preventing the blind fabric from fluttering, resulting in good stability. However, existing sunshades only provide wind resistance when the bottom rod is fully lowered. In actual use, the bottom rod is rarely fully lowered, and the sunshade is often in a half-open state. In this case, the bottom rod is not fixed and cannot provide wind protection, allowing the blind fabric to flutter in the wind, resulting in relatively poor overall stability. Utility Model Content

[0003] The purpose of this invention is to provide a highly stable sunshade curtain. This invention has the advantage of better overall stability.

[0004] The technical solution of this utility model is as follows: A highly stable sunshade curtain includes a roller blind. A transmission tube is located at the top of the roller blind. One end of the transmission tube is rotatably connected to the roller blind. A winding motor is located inside the other end of the transmission tube. The output end of the winding motor is connected to the transmission tube, and the other end of the winding motor is connected to the roller blind. Fabric is wound around the transmission tube. A roller blind bottom rod is located at the lower end of the fabric. A through hole is located inside the roller blind bottom rod. End caps are located at both ends of the roller blind bottom rod. Telescopic shafts that are slidably connected to the roller blind are located on the end caps. A drive rod is located inside the through hole. The two ends of the drive rod are respectively connected to the telescopic shafts of the two end caps. An adjustment knob connected to the drive rod is located on the outside of the roller blind bottom rod. The adjustment knob is used to rotate the drive rod, and the drive rod causes the telescopic shaft to move horizontally.

[0005] In the aforementioned highly stable sunshade curtain, the roller blind includes a curtain box with an opening at the bottom, and both ends of the curtain box are provided with downward-extending columns. The lower end of the columns and both ends of the curtain box are provided with decorative covers. The transmission tube is located inside the curtain box and is rotatably connected to the curtain box through a first bracket. The roller motor is fixed to the curtain box through a second bracket.

[0006] In the aforementioned highly stable sunshade curtain, the inner wall of the column is provided with a sliding groove, and a slider connected to the telescopic shaft is provided on the sliding groove.

[0007] In the aforementioned highly stable sunshade, the cross-section of the drive rod is worm gear shaped, one side of the drive rod is provided with a worm gear that connects to the adjustment knob, the end of the drive rod is screwed to the telescopic shaft, and the threads at both ends of the drive rod are turned in opposite directions.

[0008] In the aforementioned highly stable sunshade curtain, adjustment knobs are provided on both the front and rear sides of the roller blind bottom rod, and two adjustment knobs are connected to both ends of the worm gear, with the worm gear rotatably connected to the roller blind bottom rod.

[0009] Compared with existing technologies, this invention, based on existing sunshade curtains, incorporates telescopic shafts at both ends of the roller blind bottom rod, which are slidably connected to the uprights. A drive rod is installed inside the bottom rod, and an adjustment knob connecting the drive rod is located on the outside. The adjustment knob drives the drive rod, which in turn moves the telescopic shafts, establishing a frictional connection between the telescopic shafts and the uprights. This maintains a constant height of the bottom rod, preventing the fabric from fluttering in the wind. Because the telescopic shafts are slidably connected to the uprights, the bottom rod maintains a fixed height at any point, providing wind protection even without being fully lowered, resulting in better overall stability. In summary, this invention offers the advantage of superior overall stability. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: Highly stable sunshade curtains, such as Figure 1As shown, the device includes a roller shutter window. A transmission tube 1 is located at the top of the roller shutter window. One end of the transmission tube 1 is rotatably connected to the roller shutter window. A winding motor 2 is located inside the other end of the transmission tube 1. The output end of the winding motor 2 is connected to the transmission tube 1, and the other end of the winding motor 2 is connected to the roller shutter window. Fabric 3 is wound around the transmission tube 1, and a roller shutter bottom rod 4 is located at the lower end of the fabric 3. Its features are as follows: The roller shutter bottom rod 4 is made of aluminum alloy and has a through hole 5 inside. Both ends of the roller shutter bottom rod 4 are provided with end caps 6. The end caps 6 are tightly fitted and inserted into the roller shutter bottom rod 4. The end caps 6 are provided with telescopic shafts 7, which pass through the end caps 6 and are axially movable.

[0018] A drive rod 8 is installed inside the through hole 5. The two ends of the drive rod 8 are respectively screwed to the telescopic shafts 7 of the two end caps 6. The threads at the two ends of the drive rod 8 are in opposite directions. The cross-section of the drive rod 8 is worm gear shaped. The drive rod 8 is a stretched aluminum profile with threads machined at both ends. A worm gear 17 is provided on the lower side of the drive rod 8. Both ends of the worm gear 17 extend out of the bottom rod 4 of the roller shutter and are rotatably connected to the bottom rod 4 of the roller shutter. Adjustment knobs 9 are provided at both ends of the worm gear 17.

[0019] The roller blind includes a curtain box 10 with an opening at the bottom. Both ends of the curtain box 10 are provided with downward-extending posts 11. Both the curtain box 10 and the posts are made of aluminum profiles. The lower end of the posts 11 and both ends of the curtain box 10 are provided with decorative covers 12. The posts 11 and the curtain box 10 are tightly fitted and inserted with the corresponding decorative covers 12.

[0020] The transmission pipe 1 is located inside the curtain box 10. The transmission pipe 1 is rotatably connected to the curtain box 10 via the first bracket 13. The roller motor 2 is fixed to the curtain box 10 via the second bracket 14. Both the curtain box 10 and the upright 11 are fixed to the window or door opening by multiple expansion bolts or brackets.

[0021] The inner wall of the column 11 is provided with a sliding groove 15, and a slider 16 connected to the telescopic shaft 7 is provided on the sliding groove 15.

[0022] Working principle: The roller motor 2 drives the transmission tube 1 to rotate forward or backward, causing the fabric 3 to unfold or roll up on the transmission tube 1, which in turn drives the bottom rod 4 of the roller blind to rise and fall.

[0023] When the roller blind bottom rod 4 is at any height, if there is wind and to prevent the fabric 3 from being blown around, turn the adjustment knob 9. The adjustment knob 9 drives the drive rod 8 to rotate, and the drive rod 8 drives the telescopic shaft 7 to move inward. The telescopic shaft 7 presses the slider 16 against the column 11 to establish friction. The height of the roller blind bottom rod 4 remains unchanged, preventing the fabric 3 from swinging.
