Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtains, in particular to a windproof rolling curtain. Background Art

[0002] A rolling curtain is a type of window decoration product with various types and a wide range of application scenarios. The rolling curtain is made by processing curtain fabric with resin and rolled into a drum shape. It is a form of curtain that is raised and lowered by a pull rope or chain. Usually, when the rolling curtain is unfolded, the lower beam of the rolling curtain generates a vertical downward pull on the curtain fabric under the action of gravity, causing the curtain fabric to droop to achieve the shading effect. However, when used in some areas with strong winds, the curtain fabric is blown up under the action of the wind because there is no fixing device, resulting in the curtain fabric being blown up by the wind and affecting its use function.

[0003] The prior art CN203655106U discloses a windproof rolling curtain, which includes a pull rope, a pulley, a top pipe, a curtain fabric, a lower beam of the rolling curtain, a clamping block, a clamping groove, a clamping block and a rubber band. Pulling the pull rope drives the pulley to rotate, and the pulley drives the top pipe to roll up or unfold the curtain fabric; the lower beam of the rolling curtain exerts a vertical pull on the curtain fabric under the action of gravity, pulling the clamping block towards the ground side and buckling it in the clamping groove. The clamping block rebounds under the action of the rubber band and firmly clamps in the clamping groove, so that the curtain fabric and the lower beam of the rolling curtain are fixed, preventing the curtain fabric from being blown up by the wind and affecting its use function.

[0004] In normal use, in the process of restricting the curtain fabric in the prior art, it is time-consuming and laborious, and mostly inconvenient, making it inconvenient to restrict the curtain fabric to prevent the curtain fabric from being blown up by the wind, thereby affecting the use effect of the rolling curtain. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a windproof rolling curtain, which solves the problem that in the prior art, in the process of restricting the curtain fabric, it is time-consuming and laborious, and mostly inconvenient, making it inconvenient to restrict the curtain fabric to prevent the curtain fabric from being blown up by the wind, thereby affecting the use effect of the rolling curtain.

[0006] To achieve the above purpose, the utility model provides a windproof rolling curtain, which includes a rear shell and an installation component; the installation component includes a front shell, an outer cover, a roller, a curtain fabric, an outer guide rail, an inner guide rail, a weighted lower rod and a driving member. The outer cover is connected to the rear shell by bolts, the front shell is connected to the outer cover by bolts and is detachably connected to the rear shell. The driving member is arranged on the outer cover, the roller is connected to the driving member, the curtain fabric is detachably connected to the roller, the outer guide rail is connected to the outer cover by bolts, the inner guide rail is slidably connected to the outer guide rail and is slidably connected to the curtain fabric, and the weighted lower rod is slidably connected to the outer guide rail and is detachably connected to the curtain fabric.

[0007] Among them, the driving member includes a mounting bracket, a circular shaft, and a tubular motor. The mounting bracket is mounted on one side of the outer cover close to the roller through bolts; the circular shaft is detachably connected to the mounting bracket and is slidably connected to the roller; the tubular motor is inserted into the circular shaft, and the tubular motor is detachably connected to the mounting bracket.

[0008] Among them, the inner guide rail has a limiting groove, which is located on one side of the inner guide rail close to the rolling curtain cloth and cooperates with the rolling curtain cloth.

[0009] Among them, the mounting assembly further includes an anti-collision strip and a T-shaped block. The T-shaped block is slidably connected to the weighted lower rod and is located on one side of the weighted lower rod away from the rolling curtain cloth; the anti-collision strip is fixedly connected to the T-shaped block and is located on one side of the T-shaped block away from the weighted lower rod.

[0010] Among them, the weighted lower rod has a T-shaped groove, which is located on one side of the weighted lower rod close to the T-shaped block and cooperates with the T-shaped block.

[0011] For a windproof rolling curtain of the present utility model, the tubular motor drives the circular shaft to rotate. When the circular shaft rotates, it drives the roller to rotate counterclockwise. When the roller rotates, it unfolds the rolled-up rolling curtain cloth. At the same time, under the gravity of the weighted lower rod, the weighted lower rod moves on the outer guide rail. When the weighted lower rod moves, it drives the rolling curtain cloth to move on the limiting groove of the inner guide rail. With the cooperation of the inner guide rail and the weighted lower rod, during the unfolding process of the rolling curtain cloth, it is restricted at the same time, making it convenient to restrict the rolling curtain cloth, thereby preventing the rolling curtain cloth from being blown up by the wind and improving the use effect of the rolling curtain.

When the weighted lower rod 108 moves, it drives the rolling curtain 105 to move on the limiting groove of the inner guide rail 107. With the cooperation of the inner guide rail 107 and the weighted lower rod 108, during the unfolding process of the rolling curtain 105, the rolling curtain 105 is restricted at the same time, so that it is convenient to restrict the rolling curtain 105, thereby avoiding the rolling curtain 105 from being blown up by the wind, and thus improving the use effect of the rolling curtain.

The anti-collision strip 201 is made of rubber material, and the anti-collision strip 201 is located at the bottom of the T-shaped block 202. When the weighted lower rod 108 moves, it drives the anti-collision strip 201 to descend, and the anti-collision strip 201 contacts the wall surface, thereby preventing damage caused by the contact between the weighted lower rod 108 and the wall surface when it descends.

[0033] Secondly, the weighted lower rod 108 has a T-shaped groove 203, and the T-shaped groove 203 is located on the side of the weighted lower rod 108 close to the T-shaped block 202 and cooperates with the T-shaped block 202. The T-shaped groove 203 is located at the bottom of the weighted lower rod 108, and the T-shaped groove 203 is slidably connected to the outer side of the T-shaped block 202. By inserting the T-shaped block 202 into the T-shaped groove 203, the connection between the T-shaped block 202 and the weighted lower rod 108 is realized.
