Cable-type external sunshade roller blinds

Abstract

The invention discloses a guyed external sunshade roller shutter, and belongs to the field of construction external sunshade equipment. The guyed external sunshade roller shutter comprises a roller shutter body and a roller shutter retracting and releasing mechanism; the roller shutter body is wound on the exterior of the roller shutter retracting and releasing mechanism in a liftable manner; the roller shutter body is rotatably provided with a plurality of slats (4). The guyed external sunshade roller shutter is characterized by also comprising at least one rope-shaped component connected with all the slats (4); the at least one rope-shaped component and the roller shutter body are synchronously wound on the roller shutter retracting and releasing mechanism; the upper end of the at least one rope-shaped component is fixed to the roller shutter retracting and releasing mechanism; during the downward releasing process of the roller shutter body, the upper end of the at least one rope-shaped component goes on rotating along with the roller shutter retracting and releasing mechanism, and relative displacement is generated between the at least one rope-shaped component and the roller shutter body to pull the slats (4) of the roller shutter to be turned over; the at least one rope-shaped component rotates along with a reel to pull the slats to be turned over upwards, so that the slats are in an opened state to realize the automatic turnover of the slats. The guyed external sunshade roller shutter has the advantages that the structure is simple, the operation is convenient, working is reliable, and the wind-proof effect is good, and the like.

Description

technical field

[0001] The utility model relates to a cable-type external sun-shading venetian roller shutter, which belongs to the field of external sun-shading equipment for buildings. Background technique

[0002] The sunshade system is divided into inner sunshade and outer sunshade according to the relative position of its installation position and the building wall. The outer sunshade is a device installed outside the transparent enclosure of the building to block sunlight. External shading is to use a certain physical method to block solar radiant heat and sunlight from entering the interior through the building envelope. External shading is one of the effective methods for building energy-saving design in hot-summer and cold-winter regions and hot-summer and warm-winter regions in China, especially in summer, to block solar radiant heat from entering the room and to avoid indoor heat loss in winter. Comfort and light comfort. At present, two sets of operating device...

Examples

Embodiment 1

[0046] refer to Figure 1~2 In this embodiment, the roller blind retractable mechanism includes a horizontally arranged reel 1 and an adjustment part wound on the reel 1, the upper end of the venetian roller blind is connected with the lower end of the adjustment part; the upper end of the rope-like member is fixed on the adjustment part and the rope The shape part protrudes from the side of the outer side of the adjustment part. The outer side of the adjustment part is the side of the adjustment part facing away from the reel 1 when the adjustment part is wound on the reel 1. The venetian roller blind can be connected with the reel through the adjustment part. The separation of the reel 1 facilitates the connection between the reel 1 and the venetian roller blind, and facilitates the installation of rope-like components. The length of the rope-like part is greater than the height of the venetian blind, but the length of the rope-like part is less than the maximum stroke of th...

Embodiment 2

[0057] refer to Figure 12 The difference between this embodiment and Embodiment 1 is that the blade 4 is located on the outside of the venetian blind, that is, the blade 4 is rotated on the other side of the blade shaft 5 relative to the reel 1, and the upper end point of the blade cable 3 is connected to the adjustment roller blind 2 and the blade cable 3 protrudes from the outer side of the adjustment roller blind 2, and then the blade cable 3 passes from the inner surface of the adjustment roller blind 2 to the outer surface to pass the blades 4 in series, or connect to the side of the reel 1 In terms of the effective area, the effective area of ​​the reel 1 is the area located on the axially outer surface of the reel 1 and connected to the outer surface of the adjustment part. Other structures are with embodiment 1.

Embodiment 3

[0059] refer to Figure 13 In the present embodiment, vertical rails 8 are provided at both ends of the blade shaft 5, and both ends of the blade shaft 5 are longer than the blades 4 and are slidably arranged in the rails 8, and the blades 4 are rotated between the rails 8 on both sides. The two ends of the roller blind 2 are also slidably arranged in the track 8, and the two ends of the blade shaft 5 and the roller shutter shaft 201 are guided and fixed by the rail 8 to improve the windproof effect. As a further improvement, the blade 4, the blade shaft 5, and the track 8 And the adjustment roller blind 2 is made of metal, after being fixed by the track 8, the present invention can also play the anti-theft effect as an anti-theft window. Other structures are with embodiment 1 or 2.
