Description

Technical Field

[0001] This invention relates to the field of building door and window technology, and in particular to a high-sealing aluminum-wood composite heat-insulating window. Background Technology

[0002] Aluminum-wood composite doors and windows employ an exterior aluminum and interior wood structure, with most using multi-layered, double-glazed tempered glass. The metallic properties of the exterior aluminum not only make them waterproof and moisture-proof but also resistant to deformation. The interior wood is primarily made from rigorously selected Nordic red pine grown near the Arctic Circle and larch from the primeval forests of Northeast Asia, coated with imported wood-specific paint. This not only provides moisture and corrosion resistance but also offers a variety of colors, significantly enhancing the building's sophistication and creating a pleasing visual effect. The "thermal break + double glazing" structure enhances sound insulation and sealing, while also providing thermal insulation, greatly reducing energy consumption for heating and cooling. This fully embodies the energy-saving and environmentally friendly nature of these doors and windows.

[0003] Multi-layered tempered glass in aluminum-wood composite doors and windows often uses sealing strips for sealing, thereby enhancing the thermal insulation performance of the doors and windows. However, existing sealing strips are susceptible to thermal expansion and contraction due to changes in ambient temperature. When heated, the sealing strip generally expands, resulting in a tighter contact between the strip and the glass and window frame, without affecting its sealing performance. When exposed to low temperatures, the sealing strip contracts, which can easily create gaps between the strip and the glass and window frame, thus affecting its sealing and thermal insulation effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a high-sealing aluminum-wood composite heat-insulating window, thereby preventing the sealing strip from shrinking due to cold and improving the sealing performance.

[0005] This invention provides a high-sealing aluminum-wood composite heat-insulating window, comprising a window frame and a window sash. The window sash is installed on the inner side of the window frame and hinged thereto. The window sash includes a sash frame, tempered glass, and a glass mounting frame. A glass mounting frame is installed on the inner side of the sash frame, and multiple pieces of tempered glass are installed on the inner side of the glass mounting frame. A central sealing strip is installed at the edge between adjacent tempered glass panes, and the tempered glass at both ends is tightly fitted to the inner wall of the glass mounting groove. The invention is characterized in that the glass mounting frame seals the tempered glass through a sealing mechanism, which includes a central sealing strip, a clamping plate, and a piston. The glass mounting frame has cylindrical cavities and placement slots at both ends of its two side walls, with the cylindrical cavities and placement slots corresponding to each other. A piston is installed inside the cylindrical cavity, and the piston is connected to the inner wall of the cylindrical cavity facing outward by a compression spring. The compression cavity formed between the piston and the inner wall of the cylindrical cavity facing inward is filled with compressed gas, which partially compresses the compression spring through the piston. The intermediate sealing strip has a sealed cavity inside, and the compressed cavity communicates with the cavity of the intermediate sealing strip through a connecting hole. The cavity of the intermediate sealing strip is filled with gas, causing the intermediate sealing strip to expand.

[0006] The aforementioned window sash frame includes a wooden window sash frame and an external aluminum sash frame. The external aluminum sash frame is fixedly installed on the exterior-facing side of the wooden window sash frame to form a complete window sash frame.

[0007] The window frame described above has a groove on the inside, and a glass mounting frame is installed in the groove of the window frame.

[0008] A buffer pad is installed between the tempered glass at both ends and the inner wall of the glass mounting groove. The buffer pad has a certain degree of elasticity and sealing.

[0009] The glass mounting frame described above has a mounting base installed in the glass mounting groove. The mounting base is sandwiched between two adjacent tempered glass panes and is used to install the intermediate sealing strip.

[0010] The aforementioned glass mounting frame has a cylindrical cavity on its end wall, and a piston is installed inside the cylindrical cavity. The piston is connected to the inner wall of the cylindrical cavity facing outward by a compression spring. The compression cavity formed between the piston and the inner wall of the cylindrical cavity facing inward is filled with compressed gas. The compressed gas partially compresses the compression spring through the piston. The two inner walls of the groove of the window frame are connected to the tempered glass at both ends by end sealing strips. The end sealing strip has a sealed cavity inside, and the compression cavity is connected to the cavity of the end sealing strip through a connecting hole. The cavity of the end sealing strip is filled with gas, causing the end sealing strip to expand.

[0011] The depth of the aforementioned placement groove is greater than the thickness of the two side walls of the glass mounting groove. The outer end of the cylindrical cavity is provided with a guide hole that communicates with the placement groove. A clamping plate is installed inside the placement groove. The clamping plates at both ends of the glass mounting frame are in contact with the tempered glass at both ends. The piston is connected to the inner end of the connecting rod, and the outer end of the connecting rod passes through the guide hole and is connected to the clamping plate.

[0012] The aforementioned compressed cavity is connected through a connecting hole, which is connected to the cavity of the intermediate sealing strip through a connecting pipe.

[0013] Compared with the prior art, the present invention has the following outstanding advantages:

[0014] 1. When the end sealing strip and the middle sealing strip of the present invention are cooled and contracted, the gas inside them is cooled and contracted, the pressure decreases, the compression spring relaxes, and the piston squeezes the compression cavity, squeezing the gas in the compression cavity into the end sealing strip and the middle sealing strip, so that the end sealing strip and the middle sealing strip re-expand and restore to the volume before contraction, reaching a new equilibrium, thereby preventing the end sealing strip and the middle sealing strip from contracting and affecting the sealing performance.

[0015] 2. When the end sealing strip and the middle sealing strip of the present invention expand due to cold, when the internal gas pressure is greater than the spring force of the compression spring, they compress the compression spring, making the volume of the compression cavity larger, so that a part of the gas in the cavity of the end sealing strip and the middle sealing strip enters the compression cavity, thus avoiding the end sealing strip and the middle sealing strip from over-expanding and breaking.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the present invention includes a window frame 1 and a window sash 2, the window sash 2 being installed on the inner side of the window frame 1 and hinged thereto.

[0022] The window frame 1 comprises an aluminum outer frame and a wooden inner frame, which are fitted together to form a complete window frame 1. The window frame 1 is an existing device, and its specific structure will not be described in detail.

[0023] The window sash 2 includes a window sash frame 21, tempered glass 23, glass mounting frame 22 and sealing mechanism 24. The window sash frame 21 includes a wooden window sash frame 212 and an external aluminum sash frame 211. The external aluminum sash frame 211 is fixedly installed on the side of the wooden window sash frame 212 facing the outside, forming a complete window sash frame 21.

[0024] In the optimized solution, the wooden window sash frame 212 and the external aluminum sash frame 211 are hollow structures with internal heat insulation cavities.

[0025] like Figures 2-4 As shown, the glass mounting frame 22 seals the tempered glass 23 through a sealing mechanism 24, which includes an intermediate sealing strip 245, a clamping plate 241, and a piston 243.

[0026] The window frame 21 has a groove on its inner side, and a glass mounting frame 22 is installed in the groove of the window frame 21. The glass mounting frame 22 has a glass mounting groove on its inner side, and multiple pieces of tempered glass 23 are installed in the glass mounting groove. A middle sealing strip 245 is installed at the edge between two adjacent pieces of tempered glass 23, and the tempered glass 23 at both ends is tightly fitted to the inner wall of the glass mounting groove.

[0027] In the optimized solution, a buffer pad is installed between the tempered glass 23 at both ends and the inner wall of the glass mounting groove. The buffer pad has a certain degree of elasticity and sealing.

[0028] A mounting base 244 is installed in the glass mounting groove of the glass mounting frame 22. The mounting base 244 is sandwiched between two adjacent tempered glass panes 23 and is used to install the intermediate sealing strip 245. The mounting base 244 is made of elastic material and can produce a small amount of elastic deformation when compressed.

[0029] The glass mounting frame 22 has multiple linearly and uniformly distributed cylindrical cavities and placement grooves at both ends of its two side walls. The cylindrical cavities and placement grooves are positioned corresponding to each other. The depth of the placement grooves is greater than the thickness of the two side walls of the glass mounting grooves. The outer end of the cylindrical cavity is provided with a guide hole that communicates with the placement groove. A clamping plate 241 is installed in the placement groove. The clamping plates 241 at both ends of the glass mounting frame 22 are in contact with the tempered glass 23 at both ends.

[0030] A piston 243 is installed inside the cylindrical cavity. The piston 243 is connected to the inner end of the connecting rod 242. The outer end of the connecting rod 242 passes through the guide hole and is connected to the clamping plate 241. The piston 243 is connected to the inner wall of the cylindrical cavity facing outward by a compression spring. The compression cavity formed between the piston 243 and the inner wall of the cylindrical cavity facing inward is filled with compressed gas. The compressed gas partially compresses the compression spring through the piston 243.

[0031] The intermediate sealing strip 245 has a sealed cavity inside and is made of a rubber material with a certain degree of elasticity. Multiple compression cavities on each side wall of the glass mounting frame 22 are connected by connecting holes, which are connected to the cavity of the intermediate sealing strip 245 via connecting pipes. Gas is injected into the cavity of the intermediate sealing strip 245, causing it to expand and thus enabling it to make tight contact with the tempered glass 23 at both ends.

[0032] In the optimized scheme, the upper and lower end walls of the glass mounting frame 22 are respectively provided with multiple cylindrical cavities that are linearly and uniformly distributed. A piston 243 is installed in the cylindrical cavity. The piston 243 is connected to the inner wall of the cylindrical cavity facing outward by a compression spring. The compression cavity formed between the piston 243 and the inner wall of the cylindrical cavity facing inward is filled with compressed gas. The compressed gas partially compresses the compression spring through the piston 243.

[0033] The inner walls of the groove in the window sash frame 21 are connected to the tempered glass 23 at both ends by end sealing strips 25. The end sealing strip 25 has a sealed cavity inside and is made of a rubber material with a certain degree of elasticity. Multiple compression cavities on the upper and lower end walls of the glass mounting frame 22 are connected by connecting holes, which are connected to the cavities of the end sealing strip 25 via connecting pipes. Gas is injected into the cavities of the end sealing strip 25, causing it to expand and thus enabling it to make tight contact with the tempered glass 23 at both ends.

[0034] The air pressure in the end sealing strip 25 and the middle sealing strip 245 is the same as the air pressure in the corresponding compressed cavity.

[0035] In this embodiment, the gas is carbon dioxide.

[0036] The operation process is as follows: When the end sealing strip 25 and the middle sealing strip 245 of the present invention are cooled and contracted, the gas inside them is cooled and contracted, the pressure decreases, the compression spring relaxes, and the piston 243 squeezes the compression cavity, forcing the gas in the compression cavity into the end sealing strip 25 and the middle sealing strip 245, so that the end sealing strip 25 and the middle sealing strip 245 re-expand and return to their original volume before contraction, until a new force balance is reached. During the movement of the piston 243 on both sides of the glass mounting frame 22, it drives the clamping plate 241 to move inward through the connecting rod 242, thereby pressurizing the tempered glass 23 inward, so that it fits tightly against the middle sealing strip 245. When the end sealing strip 25 and the middle sealing strip 245 expand due to cold, when the internal gas pressure is greater than the spring force of the compression spring, they compress the compression spring, making the volume of the compression cavity larger. This allows some of the gas inside the cavity of the end sealing strip 25 and the middle sealing strip 245 to enter the compression cavity, thus preventing the end sealing strip 25 and the middle sealing strip 245 from expanding and rupturing.

[0037] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes made to it without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
