Background

The curtain cloth of the traditional roller shutter slides up and down on the surface of the window frame or the side rail, and the lower end of the curtain cloth freely sags, so that the lower end of the curtain cloth is easy to blow by wind. In order to prevent wind from blowing on the curtain, a zipper or a bead is used to connect the curtain to the side rail while sliding, and various wind-proof roller blinds are produced according to the lateral fixing method. Chinese patent application No. 202110787299X discloses a wind-resistant roller shutter that uses running beads to attach the curtain to the side rails.

The wind-proof rolling curtain is the same as other existing rolling curtains, and is characterized in that a scroll is fixedly arranged at the upper end of a window, and the scroll is rotated to wind or release curtain cloth. The window curtain is firstly opened from the lower part of the window, so that the upper part of the window is shaded, the lower part of the window is lighted, the lower part of the window can not shade the sight line when opened, and the upper part of the window can not be lighted. However, in real life, private spaces such as rooms, meeting rooms, toilets and the like, school classrooms and office places often require the lower half of a window to shield vision, and the upper half is used for lighting. There is a need for an upward opening roller blind. In order to shade the sight or direct light at different positions, the shutter is required to shade the middle part or the upper part of the window, and the ideal shutter can prevent wind, spread out at any position and shade any position of the window.

Chinese patent ZL201310342886.3 discloses an upward-opening roller shutter, and the patent makes the haulage rope drive the reel to rotate while driving the reel to lift by connecting the two ends of the reel with a movable pulley mechanism, thereby realizing the dynamic upward-opening roller shutter effect. Chinese patent ZL201510232038.6 discloses a roller blind type curtain which can be opened at any position and which is characterized in that a roller shaft is rotated while being lifted. The Chinese patent ZL201810513089.X discloses a roller shutter which does not depend on gravity and can be opened and closed freely up and down. Chinese patent ZL202020173013 discloses another roller shutter with liftable roller shafts, two sides of which are provided with guide grooves, and sliding grooves and driving grooves are arranged in the guide grooves. The rack is arranged in the driving groove, the gear is arranged on the scroll, and the motor drives the gear to rotate so as to drive the scroll to rotate and lift along the rack, so that the opening and closing or lifting of the roller shutter are realized. The Chinese patent ZL2022213630269 develops a new way, adopts the tensioning up and down of curtain cloth and attaches to a window frame, drives the center of a scroll to move up and down, realizes the up and down opening and closing of the roller shutter and achieves the windproof effect.

The present utility model is a further improvement on the above utility model.

Disclosure of Invention

A wind-proof rolling curtain comprises a scroll, curtain cloth and side rails, wherein the scroll, a limiter and a traction device are arranged, the scroll and the scroll are coaxially connected, the scroll and the side rails are meshed with each other, one end of the limiter is connected with a center shaft of the scroll, the other end of the limiter is connected with the side rails in a sliding manner, and the traction device drives the limiter to reciprocate along the side rails. The function of the stop is to maintain the wheel and side rail in an intermeshed condition during movement. Thus, when the limiter is driven to reciprocate along the side rail, the reel can be driven by the rotating wheel to rotate and lift.

Preferably, the side rail is provided with a rack, and the rotating wheel is a gear meshed with the rack.

Preferably, the reel is coaxially connected with the rotating wheel through a tensioning spring. When the upper lifting scroll and the lower lifting scroll are adopted, the tensioning spring is arranged for keeping the curtain cloth in a tensioning state all the time. At least one spool is coaxially connected to the wheel by a tension spring. The tensioning spring can be hidden in the scroll, so that the rolling curtain is attractive and compact.

Preferably, the retractor is a synchronous belt driven by a motor.

The winding shaft comprises a first winding shaft and a second winding shaft, and two ends of the curtain cloth are respectively wound on the first winding shaft and the second winding shaft.

Description of the embodiments

The technical scheme of the utility model is further described below with reference to the embodiment and the attached drawings.

Examples

As shown in fig. 1, the rotating wheel 3 is a gear, the side rail 2 is provided with a rack 4, and the rotating wheel 3 and the rack 4 are meshed with each other. One end of the limiter 5 is connected with the center shaft 6 of the rotating wheel, one end of the limiter is in sliding connection with the side rail 2, and the tractor 7 drives the limiter 5 to slide up and down along the side rail 2. The turning wheel 3 can move up and down by the action of the stopper 5, and the turning wheel 3 rotates while ascending and descending because the turning wheel is always kept in an intermeshed state with the side rail 2 during the up and down movement.

Fig. 2 is a schematic view of the front structure of the wind-proof rolling shutter of the present utility model. As shown in fig. 2, the reel 1 and the rotating wheel 3 are coaxially and fixedly connected, and the reel 1 and the rotating wheel 3 are coaxially connected with the central shaft 6 of the rotating wheel. When the rotating wheel 3 rotates while ascending and descending, the reel 1 is driven to ascend and descend and rotate. This allows the winding or releasing of the curtain of the wind-resistant roller blind of the utility model.

Examples

In this embodiment, the arrangement of the wheel 3, rack 4, stopper 5, wheel center shaft 6, retractor 7 and side rail 2 is the same as that of embodiment 1, but as shown in fig. 3, the reel 1 and wheel 3 are coaxially connected with the wheel center shaft 6 by a tension spring 8. When the rotating wheel 3 rotates while lifting, the rotation torque drives the scroll 1 to rotate through the tensioning spring 8. Due to the torsion of the tensioning spring 8, the synchronism between the winding shaft 1 and the rotating wheel 3 can be automatically adjusted, so that the curtain cloth wound on the winding shaft is always in a tensioning state.

Examples

As shown in fig. 4, in this embodiment, a first reel 11 and a second reel 12 are provided, and the upper end of the curtain 9 is wound around the first reel 11 clockwise, and the lower end is wound around the second reel 12 counterclockwise. A tension spring 8 is arranged between the second reel 12 and the wheel 3. The torsion of the tensioning spring 8 acts on the second reel 12 in a counter-clockwise direction so that the curtain 9 is always in tension.

Examples

In this embodiment, as shown in fig. 5, the first reel 11, the second reel 12 and the curtain 9 are arranged as in embodiment 3, but a tension spring 8 is also arranged between the first reel 11 and the wheel 3. The torsion of the tensioning spring 8 acts on the first reel 11 in a clockwise direction so that the curtain 9 is always in tension. The curtain cloth 9 has the advantages that the two ends of the curtain cloth 9 can be still kept tensioned in a non-sliding state of the curtain cloth 9 relative to the side rail 2, so that the curtain cloth 9 can be attached to the side rail 2, and the wind resistance and privacy protection of the curtain cloth are improved. The meaning of the adhesion is that the two surfaces can be adhered to each other when approaching, and can be peeled off nondestructively. When the curtain cloth and the side rail of the present embodiment are in a non-sliding state, the curtain cloth may be attached to the side rail and peeled from the side rail by rotation of the reel.
