Description

Technical Field

[0001] This utility model relates to the field of louver technology, and more specifically, to a sealed, high-performance heat-insulating louver. Background Technology

[0002] Currently, louvers are a common architectural shading facility widely used in residential, office and commercial spaces. Their main functions include heat insulation, light blocking and regulating indoor lighting. Traditional louvers consist of multiple horizontal or vertically arranged blades. By adjusting the angle of the blades, the amount of light entering can be controlled, while reducing the accumulation of heat from solar radiation, thereby reducing air conditioning energy consumption.

[0003] However, existing venetian blinds present a contradiction between ventilation and light blocking in actual use. Specifically, when the window is opened to allow natural wind, the venetian blind blades are easily affected by the wind and sway or shift, resulting in irregular gaps between the blades. In addition, the structural stability is poor. Traditional venetian blind blades are mostly adjusted in angle by ropes or linkage mechanisms, but the connection between the blades and the guide rail or bracket lacks an effective wind-resistant fixing mechanism; the pull rope is easily tangled under the action of wind.

[0004] Therefore, it is necessary to develop a sealed, high-performance heat-insulating louver. Utility Model Content

[0005] This invention provides a sealed, high-performance heat-insulating louver to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a sealed high-performance heat-insulating louver, comprising: a fixed upper beam, a suspended lower beam, a pull cord structure, and multiple light-blocking louvers. The pull cord structure is disposed on the fixed upper beam, and the light-blocking louvers are disposed on the pull cord structure. A beaded structure is also disposed on one side of the fixed upper beam, and a sealing structure is disposed at the bottom of the suspended lower beam. The sealing structure includes two sealing strips, and a portion of the beaded structure is adapted to be engaged between the two sealing strips.

[0007] In a preferred embodiment, the bead string structure includes a connecting rope on which adjusting beads are evenly distributed.

[0008] In a preferred embodiment, the sealing structure further includes a counterweight plate disposed on the bottom surface of the suspended lower beam, and the sealing strip disposed on the bottom surface of the counterweight plate.

[0009] In a preferred embodiment, the bottom surface of the sealing strip is a pressing plane, and the two pressing planes are adapted to abut against the windowsill surface.

[0010] In a preferred embodiment, one side of the sealing strip is an arc-shaped concave surface.

[0011] In a preferred embodiment, a limiting recess is formed between the two arc-shaped concave surfaces, the limiting recess being adapted to retain the adjusting bead.

[0012] In a preferred embodiment, the entrance of the limiting recess has an opening groove, the width of which is 1 / 3 of the diameter of the adjusting bead.

[0013] In a preferred embodiment, the furthest distance between the two arcuate concave surfaces is greater than the diameter of the adjusting bead.

[0014] In a preferred embodiment, the bottom of the limiting recess is provided with a rounded chamfered surface.

[0015] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0016] By setting two sealing strips, double sealing and light blocking are achieved, reducing the probability of light leakage and enhancing the light blocking effect;

[0017] By setting limiting recesses, a relatively fixed effect is achieved on the overall beaded structure, avoiding the phenomenon of light leakage caused by the beaded structure entangled with the light-blocking louvers.

[0018] By setting a counterweight plate and two sealing strips, the lower beam of the suspension and the bottom surface of the louver frame are made into soft contact, and the counterweighted louver can remain upright even in the presence of a slight breeze, thus preventing gaps and light leakage.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] Please see Figures 1 to 4 This utility model provides a sealed high-performance heat-insulating louver, including: a fixed upper beam 100, a suspended lower beam 200, a pull rope structure 300, and multiple light-blocking louvers 400. The fixed upper beam 100 is used to fix it to the top frame of the window. The pull rope structure 300 and multiple light-blocking louvers 400 are arranged between the fixed upper beam 100 and the suspended lower beam 200. The pull rope structure 300 is arranged on the fixed upper beam 100, and the light-blocking louvers 400 are arranged on the pull rope structure 300. A beaded structure 500 is also provided on one side of the fixed upper beam 100. Similar to the prior art, the beaded structure 500 in this embodiment is used to adjust the opening and closing state of the light-blocking louvers 400. The beaded structure 500 allows the light-blocking louvers 400 to move up and down or rotate. In order to prevent the beaded structure 500 from getting tangled on the light-blocking louvers 400 when the window is open for ventilation, part of the beaded structure 500 is adapted to be stuck between two sealing strips 602. The bead string structure 500 includes a connecting rope 501, on which adjusting beads 502 are evenly arranged. After the light-blocking louver 400 is adjusted to the ideal state by the bead string structure 500, one adjusting bead 502 at the lowest horizontal line can be inserted between two sealing strips 602, thereby achieving relative fixation of the bead string structure 500.

[0027] like Figures 3 to 4 As shown, to enhance the light-blocking strength of the Venetian blinds during use, a sealing structure 600 is provided at the bottom of the lower beam 200. The sealing structure 600 includes a counterweight plate 601 and two sealing strips 602. The counterweight plate 601 is located on the bottom surface of the lower beam 200, and the sealing strips 602 are located on the bottom surface of the counterweight plate 601. The bottom surface of the sealing strips 602 is a pressing plane 604, and the two pressing planes 604 are adapted to abut against the windowsill surface. Compared with the prior art, which uses only one plane to abut against the bottom surface of the window frame to prevent light from passing through the bottom gap, the two sealing strips 602 in this embodiment achieve double sealing and light blocking, reducing the probability of light leakage and enhancing the light-blocking effect.

[0028] like Figures 3 to 4As shown, one side of the sealing strip 602 is an arc-shaped concave surface 603. A limiting recess 606 is formed between the two arc-shaped concave surfaces 603. The limiting recess 606 formed between the two arc-shaped concave surfaces 603 is used to insert the adjusting bead 502 to achieve the overall fixing effect of the bead string structure 500. The limiting recess 606 is suitable for retaining the adjusting bead 502. The entrance position of the limiting recess 606 has an opening groove 605, the width of which is 1 / 3 of the diameter of the adjusting bead 502. The farthest distance between the two arc-shaped concave surfaces 603 is greater than the diameter of the adjusting bead 502. The bottom of the limiting recess 606 is provided with a rounded chamfered surface. The opening groove 605 is used to prevent the adjusting bead 502 from falling out without external force, and the rounded chamfered surface facilitates the insertion of the adjusting bead 502.

[0029] In summary, the beneficial effects of this utility model are as follows: by setting two sealing strips 602, double sealing and light blocking are achieved, reducing the probability of light leakage and enhancing the light blocking effect; by setting the limiting recess 606, the overall relative fixation effect of the bead string structure 500 is achieved, avoiding the phenomenon of light leakage caused by the bead string structure 500 wrapping around the light blocking louver 400; in addition, by setting the counterweight plate 601 and two sealing strips 602, the suspended lower beam 200 and the bottom surface of the louver frame are in soft contact, and the counterweighted louver can remain upright even when there is a slight breeze, avoiding the phenomenon of light leakage caused by gaps.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
