Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a seamless, moisture-proof, thermally broken sliding window. Background Technology
[0002] In the field of building doors and windows, sliding windows bring many conveniences to users with their unique opening method. However, existing sliding windows have some significant defects that urgently need to be improved through innovative technologies. Traditional sliding windows are usually assembled by splicing, which makes the window frame prone to cracking and deformation at the splicing gaps during long-term use. Once the gaps become larger, it not only affects the overall aesthetics of the window, but more seriously, it reduces the window's airtightness. Rainwater, dust and other impurities from the outside will enter the room through these gaps, causing indoor environmental pollution. At the same time, it will also accelerate the corrosion of the internal structure of the window and shorten the window's service life.
[0003] Poor moisture-proof performance is also a major drawback of traditional sliding windows. In humid environments, especially during the plum rain season in the south or in areas near the sea, ordinary sliding windows cannot effectively prevent moisture from entering. Moisture condenses into water droplets on the window frame and sash, and long-term accumulation will cause mold and rot in wooden window frames and rust in metal window frames, thus affecting the normal use of the windows and potentially damaging surrounding walls, furniture, etc.
[0004] In addition, the thermal break structure of traditional sliding windows is often not perfect. The thermal break technology aims to separate the inner and outer parts of the aluminum alloy window frame with thermal break strips to improve the thermal insulation performance of the window. However, some sliding windows have unreasonable thermal break designs and substandard thermal break strips, which greatly reduces the thermal insulation effect. In winter, indoor heat is easily lost to the outside through the windows, increasing heating costs. In summer, outdoor heat is easily transferred into the room, affecting the cooling effect of indoor air conditioning and consuming more electricity.
[0005] To address the issues of gaps between seams, insufficient moisture resistance, and structural defects in traditional sliding windows, developing a seamless, moisture-proof, thermally broken sliding window is of significant practical importance and market demand. This will bring new technological breakthroughs and product upgrades to the building doors and windows industry. Utility Model Content
[0006] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a seamless, moisture-proof, thermally broken sliding window that can solve the above-mentioned problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a seamless, moisture-proof, thermally broken sliding window, including a window frame, on which two sliding grooves are provided, and a first sealing strip is snapped onto the window frame, with two first sealing strips located on both sides of the window frame respectively;
[0008] A third sealing strip is snapped onto the slide groove, and two third sealing strips are provided on each slide groove, located on both sides of the slide groove;
[0009] A fan frame is provided on the slide, and a pulley is rotatably connected to the bottom of the fan frame;
[0010] The bottom of the chute has a drain outlet, and the sash frame is fitted with double-glazed glass, which consists of two layers of glass.
[0011] Preferably, the drain outlet is L-shaped and extends to the side of the window frame.
[0012] Preferably, a second sealing strip is adhered to the outer side of the connection between the fan frame and the insulating glass;
[0013] Moisture-proof strips are snapped onto the outer side of the fan frame;
[0014] The bottom of the fan frame is fitted with a dustproof edge.
[0015] Preferably, the dustproof edge is located at the bottom of the fan frame and on both sides of the pulley.
[0016] Preferably, the fan frame is provided with a heat insulation strip inside.
[0017] Preferably, the heat insulation strip is wavy.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] (1) When the window sash is closed, the moisture-proof strip can fit tightly against the window frame, effectively blocking rainwater from seeping into the room from the bottom and sides. It can also play a certain role in sound insulation and shock absorption. When rainwater enters the track, it will flow along the track to the drain outlet and be quickly discharged to the outside, avoiding rainwater accumulation in the track and leakage.
[0020] (2) This seamless, moisture-proof, thermally broken sliding window achieves integrated molding of the window frame and sash frame through an ultra-large extrusion process, completely solving the leakage and strength problems caused by traditional splicing processes, improving the overall performance and aesthetics of the window. It innovatively sets three different sealing strips: the outer side is weather-resistant and dustproof, the middle side ensures sealing, and the inner side fills the gaps. Combined with high-density moisture-proof strips on the bottom and sides of the window sash, it forms an all-round, multi-layer sealing system, which greatly improves the moisture-proof, dust-proof, and sound insulation effects.

[0031] Please see Figure 1-4This utility model provides a technical solution: a seamless, moisture-proof, thermally broken sliding window, including a window frame 1, a sliding groove 2 on the window frame 1, two sliding grooves 2, a first sealing strip 3 snapped onto the window frame 1, two first sealing strips 3 are provided, respectively located on both sides of the window frame 1, a third sealing strip 5 snapped onto the sliding groove 2, two third sealing strips 5 are provided on each sliding groove 2, located on both sides of the sliding groove 2, a sash frame 6 is provided on the sliding groove 2, the bottom of the sash frame 6 is rotatably connected to a pulley 12, the sash frame 6 moves horizontally on the sliding groove 2 by rolling on the pulley 12, and a drain outlet 8 is provided on the inner bottom surface of the sliding groove 2, the drain outlet 8 is L-shaped and extends to the side of the window frame 1;
[0032] The sash frame 6 is equipped with a double-glazed glass 11, which consists of two layers of glass with a hollow space between them, thereby enhancing the windproof and heat insulation performance of the sliding window.
[0033] A second sealing strip 4 is bonded to the outside of the connection between the sash frame 6 and the insulated glass 11. A moisture-proof strip 7 is snapped onto the outside of the sash frame 6. A dustproof edge 10 is snapped onto the bottom of the sash frame 6.

When rainwater enters the slide 2, it will flow along the slide 2 to the drain outlet 8 and be quickly discharged to the outside, avoiding rainwater accumulation in the slide 2 and leakage. The window frame 1 and sash frame 6 are integrated through ultra-large extrusion process, which completely solves the leakage and strength problems caused by traditional splicing process, improves the overall performance and aesthetics of the window. The innovative design sets three different sealing strips: the outer one is weather-resistant and dustproof, the middle one ensures sealing, and the inner one fills the gaps. Combined with the high-density moisture-proof strips 7 at the bottom and sides of the window sash, it forms an all-round, multi-layer sealing system, which greatly improves the moisture-proof, dustproof and sound insulation effects.
