Technical Field
[0001] This utility model relates to the field of aluminum alloy sliding door and window technology, and in particular to a heat-insulating aluminum alloy sliding door and window. Background Technology
[0002] Sliding doors and windows can be divided into two types according to the direction of sliding: horizontal sliding windows and vertical sliding windows. Sliding windows can also be divided into waterproof and heat-insulating types according to their protective functions. Most sliding doors and windows on the market have waterproof and heat-insulating functions. The waterproofing of this type of door and window is generally achieved by using sealing strips and drainage holes. The heat insulation of this type of door and window is achieved by using some heat-insulating materials to process the door and window, thereby giving the door and window a certain degree of heat insulation.
[0003] Existing aluminum alloy sliding doors and windows often experience high temperatures due to sunlight exposure at the glass, leading to increased indoor temperatures. While some windows are fitted with heat-insulating films, this insulation is typically only needed in summer. This can impair light transmission during seasons when insulation is not required, making the heat-insulating film application method inadequate. To address the periodic heat insulation needs of aluminum alloy sliding doors and windows, we propose a heat-insulating aluminum alloy sliding door and window design. Utility Model Content
[0004] The main objective of this invention is to provide a heat-insulating aluminum alloy sliding door and window. A heat-insulating mechanism is installed at the door / window frame, creating a side-pull heat-insulating structure. When the heat-insulating film is pulled out and fixed at the U-shaped plate, it can cover and insulate the door / window frame, allowing for on-demand light and heat insulation. After the heat-insulating film is pulled open at the U-shaped plate, it is elastically pulled by a spring, automatically retracting into the vertical box for storage. This effectively ensures normal light transmission at the door / window frame during seasons when heat insulation is not required, effectively solving the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A heat-insulated aluminum alloy sliding door and window includes a door and window frame and a heat insulation mechanism. The heat insulation mechanism includes an L-shaped bottom connecting plate, a vertical box, a U-shaped fixed plate, a core column, a spring, a heat insulation film, a cover, a rubber handle, and a fixed rod. The L-shaped bottom connecting plate is bolted to the outside of the bottom frame plate of the door and window frame. The vertical box and the U-shaped fixed plate are symmetrically welded to the upper surface of the L-shaped bottom connecting plate. The vertical box and the U-shaped fixed plate cover the outside of the vertical frame plate of the door and window frame, and the top of the vertical box faces... A column hole is provided at the bottom, and a core column is fixed in the center of the bottom wall of the column hole. The heat insulation film is connected to the outside of the core column by a spring. The spring and the film body of the heat insulation film are inserted into the column hole. A side slit is provided on the side of the vertical box at the wall of the column hole towards the U-shaped fixed plate. A rubber handle is fixed to the outer edge of the heat insulation film extending out of the side slit. A fixed hole for fixing the fixed rod is provided on the surface of the rubber handle. The top of the vertical box is sealed with a cover for the column hole by bolts.
[0007] Furthermore, the core column is fitted with a spring, and the inner spring plate of the spring is inserted into the surface groove of the core column. The spring bar of the spring is bonded and fixed to the surface of the heat insulation film.
[0008] By adopting the above technical solution, the spring can be connected to the heat insulation film after the spring is locked at the core post. When the heat insulation film is pulled out of the side opening, the spring can be pulled out. When the heat insulation film loses its tension, the spring can pull the heat insulation film back into the column hole of the vertical box.
[0009] Furthermore, the length of the cavity of the column hole is the same as the length of the groove of the side section;
[0010] By adopting the above technical solution, a heat insulation membrane can be passed through the side opening of the column hole.
[0011] Furthermore, an installation hole for screwing bolts is provided between the cover body of the cover and the vertical box outside the column hole, and four sets of bolts are screwed onto the top of the cover and the vertical box.
[0012] By adopting the above technical solution, the cover can be installed on the top of the vertical box with four sets of bolts to cover the column hole.
[0013] Furthermore, the length of the rubber handle is the same as the height of the heat insulation film, and the handle is inserted into the groove of the U-shaped plate.
[0014] By adopting the above technical solution, the heat insulation film can be inserted into the U-shaped fixed plate and restrained by the fixed rod with a rubber handle.
[0015] Furthermore, the depth of the cavity of the fixed hole is less than the height of the rod body of the fixed rod;
[0016] By adopting the above technical solution, the rubber handle can be inserted into the fixed rod through the fixed hole, so that the fixed rod can prevent the heat insulation film from retracting into the vertical box.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model provides a heat insulation mechanism to the frame of aluminum alloy sliding doors and windows. The heat insulation mechanism forms a side-pull heat insulation structure on the outside of the door and window frame. When the heat insulation film of the heat insulation mechanism is pulled out and fixed at the U-shaped fixed plate, the heat insulation film can cover and insulate the frame of the aluminum alloy sliding doors and windows, so that the frame of the aluminum alloy sliding doors and windows can block light and insulate as needed, thus meeting the heat insulation requirements of aluminum alloy sliding doors and windows.
[0019] Furthermore, after the heat insulation film of the heat insulation mechanism is pulled open at the U-shaped fixed plate, the heat insulation film can be elastically pulled by the spring, so that the heat insulation film is automatically rolled back into the vertical box for storage, effectively ensuring that the window frame of the aluminum alloy sliding door and window can transmit light normally in the season when heat insulation is not required.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-3As shown, a heat-insulated aluminum alloy sliding door and window includes a door and window frame 1 and a heat insulation mechanism 2. The heat insulation mechanism 2 includes an L-shaped bottom connecting plate 3, a vertical box 4, a U-shaped fixed plate 5, a core column 7, a spring 8, a heat insulation film 9, a cover 11, a rubber handle 12, and a fixed rod 14. The L-shaped bottom connecting plate 3 is bolted to the outside of the bottom frame plate of the door and window frame 1. The vertical box 4 and the U-shaped fixed plate 5 are symmetrically welded to the upper plate of the L-shaped bottom connecting plate 3. The vertical box 4 and the U-shaped fixed plate 5 cover the outside of the vertical frame plate of the door and window frame 1, and the top of the vertical box 4 faces downward. A column hole 6 is provided, and a core column 7 is fixed in the center of the bottom wall of the column hole 6. The core column 7 is connected to the heat insulation film 9 by a spring 8. The spring 8 and the film body of the heat insulation film 9 are inserted into the column hole 6. A side slit 10 is provided on the side of the vertical box 4 at the wall of the column hole 6 towards the U-shaped fixed plate 5. A rubber handle 12 is fixed to the outer edge of the heat insulation film 9 extending out of the side slit 10. A fixed hole 13 for fixing the fixed rod 14 is provided on the surface of the rubber handle 12. The top of the vertical box 4 is locked with a cover 11 that presses against the column hole 6.
[0026] The core post 7 is fitted with a spring 8, and the inner spring plate of the spring 8 is inserted into the groove on the surface of the core post 7. The spring bar of the spring 8 is bonded and fixed to the surface of the heat insulation film 9.
[0027] By adopting the above technical solution, after the spring 8 is locked at the core post 7, the spring 8 can be connected to the heat insulation film 9. When the heat insulation film 9 is pulled out of the side cutout 10, the spring 8 can be pulled out. When the heat insulation film 9 loses tension, the spring 8 can pull the heat insulation film 9 back into the column hole 6 of the vertical box 4.
[0028] The length of the cavity of the column hole 6 is the same as the length of the groove of the side section 10;
[0029] By adopting the above technical solution, the heat insulation film 9 can be passed through the column hole 6 between the side cutouts 10.
[0030] The cover 11 has an installation hole for screwing bolts between the cover body and the vertical box 4 outside the column hole 6, and the cover 11 is screwed to the top of the vertical box 4 with four sets of bolts.
[0031] By adopting the above technical solution, the cover 11 can be installed on the top of the vertical box 4 with four sets of bolts to cover the column hole 6.
[0032] The length of the rubber handle 12 is the same as the height of the heat insulation film 9, and the handle of the rubber handle 12 is inserted into the groove of the U-shaped fixed plate 5.
[0033] By adopting the above technical solution, the heat insulation film 9 can be inserted into the U-shaped fixed plate 5 by the rubber handle 12 and restrained by the fixed rod 14.
[0034] Wherein, the cavity depth of the fixed hole 13 is less than the rod height of the fixed rod 14;
[0035] By adopting the above technical solution, the rubber handle 12 can be inserted into the fixed rod 14 through the fixed hole 13, so that the fixed rod 14 can restrain the heat insulation film 9 from retracting into the vertical box 4.
[0036] It should be noted that this utility model is a heat-insulating aluminum alloy sliding door and window. After the heat insulation mechanism 2 is set at the door and window frame 1 of the aluminum alloy sliding door and window, the L-shaped bottom connecting plate 3 of the heat insulation mechanism 2 can be screwed onto the outer side of the lower frame plate of the door and window frame 1 by means of bolts. Then, the vertical box 4 and the U-shaped fixing plate 5 above the L-shaped bottom connecting plate 3 symmetrically press on the surface of the vertical frame plate of the door and window frame 1. When the door and window frame 1 needs to be heat-insulated, the rubber handle 12 can be pinched and pulled out from the side opening 10, so that the rubber handle 12 is inserted into the U-shaped fixing plate 5. The rubber handle 12 is locked in the fixing rod 14 by the fixing hole 13. When the rubber handle 12 is pulled, the heat insulation film 9 can be pulled out. The spring 8 pulls out the column hole 6 and side opening 10 of the vertical box 4, allowing the heat insulation film 9 to block the light transmission part inside the door and window frame 1. The spring 8, due to the elasticity accumulated after being pulled out, combined with the heat insulation film 9, makes it difficult for the indoor temperature of the aluminum alloy sliding door and window frame 1 to rise due to sunlight. If the aluminum alloy sliding door and window does not need heat insulation in the non-hot season, the rubber handle 12 is pulled out from the fixed rod 14 and then the rubber handle 12 is released. Under the action of the spring 8, the heat insulation film 9 can be rolled back into the column hole 6 outside the core column 7, allowing the aluminum alloy sliding door and window frame 1 to transmit light normally.
[0037] It should be noted that this utility model is a heat-insulating aluminum alloy sliding door and window. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
