Background

The wind-proof rolling curtain is a rolling curtain which is added with a function of preventing curtain cloth from being lifted by wind power on the basis of the structure, and has the advantages of compact structure and simple and convenient operation compared with other products such as folding cloth curtains or venetian blinds.

The existing windproof roller shutters in the market at present are heavy in structural design in order to achieve the windproof effect. Specifically, in the existing wind-proof rolling blind, the side posts at both sides are integrally connected to the winding device at the top and fixed on the building together with the winding device, and when the blind body is tensioned, all stress points of the side posts are concentrated at the connection part of the side posts and the winding device. On one hand, the side column needs to be designed to be thicker, so that the joint of the side column and the rolling device can have enough strength, and then the curtain body is tensioned; on the other hand, the lower beam needs to be designed to be heavier, so that enough lower tension can be provided when the lower beam is blown by strong wind, the stress of the side columns on two sides is relieved, and the deformation of the connection part of the side columns and the winding device is avoided.

Therefore, the existing windproof roller shutters need to adopt thicker side columns and heavier underbeams to ensure the stable operation of the device. The windproof roller shutter has the characteristics that the windproof roller shutter occupies larger space, is more suitable for being used in outdoor spaces such as balconies and the like, is not suitable for being used indoors, and limits the application range of the windproof roller shutter. In addition, the windproof roller shutter is heavy in structure, so that the windproof roller shutter is more in material and higher in manufacturing cost, and the popularization and the use of the windproof roller shutter are limited.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an indoor windproof roller shutter according to an embodiment of the present invention includes a winding device 1, a shutter body 2, side pillars 3 and a lower beam 4, wherein the upper end of the shutter body 2 is wound on the winding device 1, the lower end of the shutter body 2 is connected to the lower beam 4, and the side pillars 3 are respectively disposed on the left and right sides of the shutter body 2; the side columns 3 and the winding device 1 are arranged in a split mode and are respectively fixed on a building.

Specifically, as shown in fig. 2 to fig. 6, the side post 3 has a vertical guide groove 30 extending in the vertical direction, the left and right ends of the curtain body 2 have protruding flexible clamping members 20, and the left and right ends of the curtain body 2 are connected in the vertical guide groove 30 of the side post 3 in a limited manner by the flexible clamping members 20, so that the curtain body 2 is tightened in the horizontal direction and the two ends of the curtain body 2 can slide along the vertical guide groove 30.

The vertical guide groove 30 can play a role in guiding and shading, so that on one hand, the flexible clamping piece 20 at the edge of the curtain body 2 can slide up and down in the groove, and the edge of the curtain body 2 cannot slide out of the groove body; on the other hand, the gap at the edge of the curtain body 2 can be shielded, and the shading effect of the curtain body 2 is improved.

Furthermore, the lower beam 4 is provided with a horizontal limiting groove 40 extending along the horizontal direction, the lower end of the curtain body 2 is also provided with a convex flexible clamping piece 20, and the lower end of the curtain body 2 is connected in the horizontal limiting groove 40 of the lower beam 4 in a limiting manner through the flexible clamping piece 20, so that the lower end of the curtain body 2 is drooping and tensioned under the action of the gravity of the lower beam 4. The lower beam 4 can play a role of a counterweight, so that the lower end of the curtain body 2 keeps drooping, the left end and the right end of the curtain body 2 can be ensured to smoothly slide in the vertical guide grooves 30, and the blocking is avoided.

In this embodiment, the flexible clip 20 is a zipper tooth welded to the edge of the curtain body 2. The zipper teeth have enough flexibility, can be wound on the winding device 1 along with the curtain body 2, and the thickness of the zipper teeth is larger than the curtain body 2, can be connected in the vertical guide groove 30 and the horizontal limit groove 40 in a limiting manner, so that the left end, the right end and the lower end of the curtain body 2 are fixed, and then the curtain body 2 is tightened to play a role in preventing wind and shading.

Further, the lower beam 4 is located between the two side columns 3, two ends of the lower beam 4 are respectively provided with an end cover 45, and the end covers 45 are connected to the end portions of the lower beam 4 in a buckling mode.

Specifically, as shown in fig. 4 and 6, the lower beam 4 includes a main section bar 41 and a binding 42; the middle part of the main section bar 41 is provided with a clapboard, a horizontal limiting groove 40 is formed above the clapboard and is connected with the lower end of the curtain body 2, and a clamping groove 43 is formed below the clapboard;

the edge 42 is covered outside the main section 41 from the lower part, the notch of the horizontal limiting groove 40 is exposed from the upper part of the edge 42, and the bottom surface of the edge 42 covers the notch of the clamping groove 43.

Furthermore, clamping holes 44 are formed in the bottom surfaces of the edges 42 near the two ends of the lower beam 4; the end cover 45 is provided with a blocking part 451, and the blocking part 451 is inserted into the clamping groove 43, so that the end cover 45 is limited at the end part of the lower beam 4; a clamping hook 452 is arranged below the blocking part 451, and the clamping hook 452 is matched with the clamping hole 44 on the bottom surface of the binding edge 42, so that the end cover 45 is fixedly connected to the end part of the lower beam 4 in a clamping manner.

In this embodiment, the edge 42 is formed by bending a metal plate. In the existing windproof roller shutter, the lower beam is made of aluminum alloy materials, mainly because the aluminum alloy is easy to extrude and form. However, aluminum alloys have the disadvantages of being too light in weight, not light enough to be made small in size, and too heavy and large to be made large. The embodiment of the utility model provides an in the underbeam adopt the metal sheet shaping of bending, and the size is little, weighs down great, makes the structure of preventing wind the roll screen light and handy more.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
