Description

Technical Field

[0001] The utility model relates to the field of windshields, in particular to a heat-insulating windshield with automatic forward and reverse switches. Background Art

[0002] In ventilation ducts and windows, windshields are commonly used to block air. Existing windshields can be opened and closed automatically, such as shutter windshields, but cannot be opened and closed automatically in both directions and have no heat insulation properties, which is not conducive to convenient use in many aspects. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems in the prior art. To this end, the utility model proposes a heat-insulating forward and reverse automatic switch wind shield with a simple structure and easy operation.

[0004] According to the first aspect of the embodiment of the utility model, an insulated forward and reverse automatic switch windshield includes: a ventilation duct for guiding wind flow; a heat-insulating windshield with insulation material inside; a support frame with a hole for placing a movable coupling; a movable coupling placed on the heat-insulating windshield with both ends placed on the support frame; and a sealing ring for sealing the gap between the heat-insulating windshield and the support frame or the ventilation duct.

[0005] The heat-insulating windshield is counterweighted by adjusting the position of the movable coupling and the heat-insulating windshield, and the vertical ventilation duct is configured so that the areas of the heat-insulating windshields on both sides of the movable coupling are different, but the weights of the heat-insulating windshields on both sides of the movable coupling are the same. When wind passes through, the heat-insulating windshields on both sides of the movable coupling are different in force due to the different force areas and magnitudes, thereby twisting the heat-insulating windshield and automatically opening the heat-insulating windshield. When the wind stops, the weights of the heat-insulating windshields on both sides of the movable coupling are the same, so that the heat-insulating windshield automatically remains horizontal when there is no external force. , thereby automatically closing the ventilation duct. For horizontal ventilation ducts, the heat shields on both sides of the movable coupling have different areas and weights, with the upper part being lighter and the lower part being heavier. When wind passes through, the heat shields on both sides of the movable coupling are subjected to different forces due to their different areas, thus twisting the heat shields and automatically opening them. When the wind stops, the heat shields on both sides of the movable coupling have different weights, with the upper part being lighter and the lower part being heavier. This ensures that the heat shields automatically remain upright when no external force is applied, thereby automatically closing the ventilation duct. Ventilation ducts at different angles use the same principle. The sealing ring further seals the gap between the heat shield and the ventilation duct, while reducing friction.

[0006] According to an embodiment of the utility model, a heat-insulating forward and reverse automatic switch windshield has at least the following technical effects: the heat-insulating windshield has heat-insulating properties and plays a heat-insulating role. The heat-insulating windshield can automatically open in the forward and reverse directions according to the different directions of the wind, whether the wind is blowing forward or backward, and can automatically close the air outlet after the wind stops.

[0007] According to some embodiments of the present invention, the heat-insulating windshield is not only heat-insulating but also flame-retardant, and does not require any heat-insulating material or heat-insulating properties; the sealing ring around the heat-insulating windshield is made of rubber material or a brush edge;

[0008] According to some embodiments of the present invention, the heat-insulating windshield can be made into a circular, square or various other shapes.

[0009] According to some embodiments of the present invention, the support frame can be replaced by the ventilation duct itself.

[0010] According to some embodiments of the present invention, the movable coupling can be equipped with a manual or motorized device, and the heat insulation wind shield can be opened and closed by manual or mechanical control.

[0011] According to some embodiments of the present invention, the heat-insulating windshield and the movable coupling are located at one end of the heat-insulating windshield, and the heat-insulating windshield can swing left and right when hung on the movable coupling.

[0012] According to some embodiments of the present invention, the heat insulating windshield and the movable coupling are located at one end of the heat insulating windshield, and when the heat insulating windshield is suspended under the movable coupling, one part swings to the left and the other part swings to the right.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figures 1 to 3 A heat-insulating forward and reverse automatic switch windshield according to an embodiment of the present invention includes a ventilation duct 100, a support frame 110, a heat-insulating windshield 200, a movable coupling 300 and a sealing ring 400.

[0027] The ventilation duct 100 is used to guide the flow of wind; the heat-insulating windshield 200 has insulation material inside; the support frame 110 has a hole for placing a movable coupling; the movable coupling 300 is placed on the heat-insulating windshield, with both ends placed on the support frame; the sealing ring 400 is used to seal the gap between the heat-insulating windshield and the support frame or the ventilation duct.

[0028] The utility model provides a heat-insulating forward and reverse automatic switch windshield, which uses the heat-insulating windshield 200 to adjust the position through the movable coupling 300 and the heat-insulating windshield 200 for counterweight, and the vertical ventilation duct 100, so that the areas of the heat-insulating windshields 200 on both sides of the movable coupling are different, but the weights of the heat-insulating windshields 200 on both sides of the movable coupling 300 are the same.

When wind passes through, the insulating windshields 200 on either side of the movable coupling 300 experience different forces due to their different areas, causing them to twist and automatically open. When the wind stops, the insulating windshields 200 on either side of the movable coupling 300 maintain verticality when no external force is applied, thereby automatically closing the ventilation duct 100. Ventilation ducts 100 at different angles operate under the same principle. The sealing ring 400 further seals the gap between the insulating windshield 200 and the ventilation duct 100, while also reducing friction.

[0029] According to some embodiments of the present invention, the heat-insulating windshield 200 is not only heat-insulating but also flame-retardant, and does not require any heat-insulating material or heat-insulating properties.
