Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a heat-insulating and energy-saving polymer resin door and window. Background Art

[0002] Windows are an indispensable part of buildings. They are not only responsible for indoor lighting, ventilation and sound insulation, but also for heat preservation, heat insulation and aesthetics. Windows are composed of frames and glass. Windows can be used as doors, windows and skylights. Skylights are windows installed on the roof of a building, mainly for lighting and ventilation. Types of skylights: Zenith skylight: The most common type of skylight, directly installed on the roof, with good lighting effect. Raised skylight: A structure protruding from the roof, which not only provides lighting but also enhances ventilation. Recessed skylight: A certain angle is formed with the roof surface, which is conducive to the introduction of light and air circulation. Functions of skylights: Natural lighting: Skylights allow natural light to enter the room, reducing the need for lighting during the day and saving energy. Improved ventilation: Skylights can promote the circulation of indoor and outdoor air and improve air quality. Beautify space: Skylight design can enrich the indoor visual experience and add architectural aesthetic value.

[0003] Energy-saving windows are window products designed specifically to reduce building energy consumption. They achieve excellent thermal insulation effects by improving the optical properties, thermal properties and sealing of materials and improving the structure of windows. A lot of research and development efforts have been invested in the selection of materials for energy-saving windows. For example, the use of thermal break aluminum profiles and aluminum alloy thermal insulation profiles can effectively block the transfer of heat and enhance the thermal insulation performance of windows. In addition, polymer resin materials are also widely used in energy-saving windows, such as UPVC (unplasticized polyvinyl chloride) materials and polyurethane materials, because they have good thermal insulation properties and low cost.

[0004] Energy-saving windows also excel in glass configuration. Usually hollow glass or low-emissivity coated glass is used, which can effectively isolate the heat exchange between the inside and outside, and also has good sound insulation effect. More advanced technologies such as hollow built-in blinds can prevent direct sunlight in summer and reduce the burden of air conditioning and refrigeration. And vacuum glass has excellent heat insulation and sound insulation effects, but the cost is too high.

[0005] Due to its good heat insulation and sound insulation performance, hollow glass is widely used as a material for energy-saving doors and windows and glass curtain walls. Glass curtain walls play multiple roles in modern buildings, such as protecting the internal environment of the building, enhancing the architectural aesthetics, and saving energy and protecting the environment. The use of hollow glass greatly enhances the heat insulation performance of the glass curtain wall, reduces the exchange of indoor and outdoor heat energy, and achieves the effect of energy conservation and emission reduction. In addition, due to its special dry gas layer inside, hollow glass can effectively avoid internal condensation caused by temperature differences, thereby preventing early damage to the curtain wall glass and extending the service life of the building.

[0006] For example, the invention patent application with the announcement number CN117489242A provides an aluminum alloy hollow glass door and window. By setting the window frame body, window sash body, hollow glass, connecting side sleeve and locking device, the window sash body can be folded and opened and moved to one end to ensure the air permeability and brightness of the whole device. However, the hollow glass therein is prone to dents and bulges due to the pressure difference between the inside and the outside, and water vapor is easy to enter the inside of the hollow glass, affecting the use effect.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a heat-insulating and energy-saving polymer resin door and window, comprising a rectangular window frame 100, a hollow glass 200, a connecting mechanism and an adjusting mechanism, wherein the rectangular window frame 100 is installed on a wall. The hollow glass 200 comprises two flat glass sheets 201, each of which is arranged along a first direction, and the two flat glass sheets 201 are sequentially distributed along a second direction, and the first direction is perpendicular to the second direction. The first direction is the installation direction of the hollow glass 200, and if the hollow glass 200 is installed vertically, the second direction is the horizontal direction. The connecting mechanism comprises a rectangular connecting frame 300, which is fixedly arranged on the four walls of the hollow glass 200, and the rectangular connecting frame 300 is arranged on the inner side of the rectangular window frame 100, and the space between the two flat glass sheets 201 and the rectangular connecting frame 300 form an installation cavity 202.

[0036] The adjustment mechanism includes a plurality of adjustment components, which are distributed along the circumference of the insulating glass 200, and each adjustment component includes a mounting tube 400, a piston 410, an adjustment ring 420, a first spring 430, and a second spring 440. The mounting tube 400 is arranged on the rectangular connection frame 300, and the two ends of the mounting tube 400 are respectively a first end and a second end. A connecting pipe 450 is fixedly arranged at the first end of the mounting tube 400, and one end of the connecting pipe 450 is arranged in the mounting cavity 202. A connecting port 401 is opened at the second end of the mounting tube 400, and the connecting port 401 is connected to the outside.

[0037] The piston 410 is disposed in the mounting cylinder 400. The piston 410 can move along the axial direction of the mounting cylinder 400. The piston 410 divides the mounting cylinder 400 into a first cavity 402 and a second cavity 403. The first cavity 402 is connected to the connecting pipe 450, and the second cavity 403 is connected to the connecting port 401. The first spring 430 is disposed in the first cavity 402. The first spring 430 connects the piston 410 and the mounting cylinder 400. The adjusting ring 420 is disposed at the connecting port 401. The adjusting ring 420 can move along the axial direction of the mounting cylinder 400. The second spring 440 is disposed in the second cavity 403. The second spring 440 connects the adjusting ring 420 and the piston 410. The length of the adjusting ring 420 in the second cavity 403 is adjusted, so as to control the preload of the first spring 430 and the second spring 440 in the initial state. The specifications of the first spring 430 and the second spring 440 are the same.

[0038] When the heat-insulating and energy-saving polymer resin doors and windows are in use, when the air pressure in the installation cavity 202 is greater than the external air pressure, since the connecting pipe 450 connects the installation cavity 202 with the first cavity 402, and the second cavity 403 is connected with the outside, the pressure in the first cavity 402 is greater than the pressure in the second cavity 403 at this time. Under the action of the pressure difference between the first cavity 402 and the second cavity 403 and the action of the first spring 430, the piston 410 moves toward the second end of the installation cylinder 400, and the internal space of the first cavity 402 increases, thereby balancing the pressure in the installation cavity 202 and preventing the middle parts of the two flat glasses 201 from moving away from each other and deforming.

[0039] When the air pressure in the installation cavity 202 is lower than the external air pressure, the pressure in the first cavity 402 is lower than the pressure in the second cavity 403. Under the action of the pressure difference between the first cavity 402 and the second cavity 403 and the action of the second spring 440, the piston 410 moves toward the first end of the installation cylinder 400, and the internal space of the first cavity 402 is reduced, thereby balancing the pressure in the installation cavity 202 and preventing the middle parts of the two flat glasses 201 from approaching each other and deforming.

[0040] In this embodiment, each adjustment assembly further includes a fixing ring 404, which is detachably disposed in the second cavity 403, and the fixing ring 404 is concentrically disposed with the mounting tube 400. A plurality of first slide grooves 4041 are provided on the outer peripheral wall of the fixing ring 404, and the plurality of first slide grooves 4041 are distributed along the circumference of the fixing ring 404, and each first slide groove 4041 is provided along the axial direction of the mounting tube 400. A plurality of stop blocks 406 are fixedly disposed on the inner peripheral wall of the second end of the mounting tube 400, and each stop block 406 is disposed in a first slide groove 4041. A thread is provided on the inner peripheral wall of the fixing ring 404, and the adjustment ring 420 is coaxially disposed with the mounting tube 400, and a thread is provided on the outer peripheral wall of the adjustment ring 420, and the adjustment ring 420 and the fixing ring 404 are connected by threads. A retaining ring is fixedly arranged on the inner circumferential wall of the installation cylinder 400, and the retaining ring and the stopper 406 are sequentially distributed along the direction from the first end to the second end of the installation cylinder 400, and the retaining ring is used to abut against one side of the fixing ring 404 along the axial direction of the installation cylinder 400. The detachable fixing ring 404 is provided to facilitate the placement of the piston 410 into the installation cylinder 400.

[0041] During installation, the first spring 430, the piston 410, the second spring 440 and the fixing ring 404 are first placed into the installation cylinder 400 in sequence, and the stopper 406 on the fixing ring 404 is placed in the first slide groove 4041. The stopper ring is used to limit the fixing ring 404. Then, the adjusting ring 420 is threadedly matched with the fixing ring 404, and the adjusting ring 420 is screwed into the second cavity 403.

[0042] In this embodiment, along the axial direction of the mounting tube 400, one side of the adjusting ring 420 is fixedly connected to the second spring 440, and the other side of the adjusting ring 420 is provided with two clamping grooves 421. A tool is clamped in the clamping grooves 421, so that the adjusting ring 420 can be rotated conveniently.

[0043] In this embodiment, the piston 410 includes a rubber block 411 and a rubber ring 412. Along the circumference of the mounting tube 400, the outer wall of the rubber block 411 is arc-shaped, and the concave surface of the arc-shaped outer wall faces the axis of the mounting tube 400. The rubber ring 412 is sleeved on the outer side of the rubber block 411, and the inner wall of the rubber ring 412 is arc-shaped. The inner circumferential wall of the rubber ring 412 abuts against the outer circumferential wall of the rubber block 411, and the outer circumferential wall of the rubber ring 412 is in frictional contact with the inner circumferential wall of the mounting tube 400.

[0044] When the first spring 430 or the second spring 440 pushes the piston 410 to move, the push of the first spring 430 or the second spring 440 first deforms the rubber block 411, and the width of the rubber block 411 increases. After the rubber block 411 is deformed, it squeezes the rubber ring 412, thereby increasing the friction between the rubber ring 412 and the installation tube 400, so that the installation cavity 202 will not move until the pressure difference between the inside and outside of the installation cavity 202 reaches a preset size, thereby preventing the frequent movement of the piston 410 from causing excessive water vapor to enter the installation cavity 202 from the piston 410, thereby affecting the thermal insulation of the thermal insulation and energy-saving polymer resin doors and windows.

[0045] In this embodiment, a third cavity 413 is formed in the rubber block 411. A plurality of through holes 414 are formed on one side of the rubber block 411 in the second cavity 403 along the axial direction of the mounting tube 400. Water-absorbing rubber is disposed in the third cavity 413.

[0046] The water-absorbing rubber absorbs moisture in the second cavity 403 and the third cavity 413. When the external humidity is high, the water-absorbing rubber expands after absorbing water vapor. The expanded water-absorbing rubber squeezes the rubber block 411 and the rubber ring 412, thereby increasing the friction between the rubber ring 412 and the mounting cylinder 400, making the piston 410 more difficult to move.

[0047] In this embodiment, a connection disk 405 is fixedly disposed on the first end of the installation tube 400 , and the connection disk 405 and the rectangular connection frame 300 are detachably connected.

[0048] In this embodiment, along the second direction, the two sides of the insulating glass 200 are the first side and the second side, respectively, and the first side and the second side are both outside the installation cavity 202. The rectangular connection frame 300 includes a fixing frame 310, and the fixing frame 310 is provided with a first connection groove 311. The first connection groove 311 is rectangular and arranged along the circumference of the insulating glass 200. The four sides of the insulating glass 200 are arranged in the first connection groove 311. A first sealing strip is arranged in the first connection groove 311, and the first sealing strip is used to seal the gap between the two flat glasses 201. A second sealing strip is arranged at the contact point between the first side of the insulating glass 200 and the rectangular connection frame 300. A desiccant is arranged in the installation cavity 202, and the desiccant is used to absorb moisture in the installation cavity 202.

[0049] In this embodiment, the fixing frame 310 is further provided with a second connection groove 312, which is rectangular and arranged along the circumference of the insulating glass 200. The second connection groove 312 is located outside the first connection groove 311, and an aluminum strip is arranged between the first connection groove 311 and the second connection groove 312, and the aluminum strip is arranged along the circumference of the insulating glass 200. The installation tube 400 is arranged in the second connection groove 312, and one end of the connection pipe 450 passes through the aluminum strip and the first sealing strip and is arranged in the installation cavity 202.

[0050] In this embodiment, the rectangular connection frame 300 further includes a first movable frame 320 and a second movable frame 330. The first movable frame 320 is arranged along the circumference of the insulating glass 200. The first movable frame 320 is detachably arranged on the fixed frame 310 and is located in the first connection groove 311. The first movable frame 320 and the second side of the insulating glass 200 are against each other. A third sealing strip 321 is arranged at the contact point between the first movable frame 320 and the second side of the insulating glass 200. The second movable frame 330 is arranged along the circumference of the insulating glass 200. The second movable frame 330 is detachably arranged on the fixed frame 310 and is located in the second connection groove 312.

[0051] During installation, after multiple installation tubes 400 are set in the second connection groove 312, the second movable frame 330 is fixedly set in the second connection groove 312. Then, the surrounding of the insulating glass 200 is placed in the first connection groove 311, and a second sealing strip is set at the contact between the first side of the insulating glass 200 and the rectangular connection frame 300. After that, the first movable frame 320 is fixedly set on the second side of the insulating glass 200, and a third sealing strip 321 is set at the contact between the first movable frame 320 and the second side of the insulating glass 200. Thus, the installation of the heat-insulating and energy-saving polymer resin door and window is completed.

[0052] In this embodiment, the rectangular window frame 100 includes a plurality of frames, which are connected end to end. The fixed frame 310 includes a plurality of frames, which are distributed along the circumference of the insulating glass 200, and the plurality of frames are connected end to end. The first movable frame 320 includes a plurality of first connecting rods, which are connected end to end. The second movable frame 330 includes a plurality of second connecting rods, which are connected end to end. The frame, the first connecting rod and the second connecting rod are made of polymer resin material.

[0053] Working process: first, put the first spring 430, the piston 410, the second spring 440 and the fixing ring 404 into the installation tube 400 in sequence, then thread the adjusting ring 420 and the fixing ring 404 together, and screw the adjusting ring 420 into the second cavity 403. The first spring 430 and the second spring 440 are in a compressed state, and at this time, since the first end and the second end of the installation tube 400 are connected to the outside world, the extended lengths of the first spring 430 and the second spring 440 are the same.

[0054] After multiple installation tubes 400 are arranged in the second connection groove 312, the second movable frame 330 is fixedly arranged in the second connection groove 312. Then, the fixed frame 310 is connected to the insulating glass 200, that is, the four sides of the insulating glass 200 are in the first connection groove 311, and then the second sealing strip is arranged at the contact between the first side of the insulating glass 200 and the rectangular connection frame 300. The first movable frame 320 is fixedly arranged on the second side of the insulating glass 200, and the third sealing strip 321 is arranged at the contact between the first movable frame 320 and the second side of the insulating glass 200. Finally, the assembled insulating glass 200 and the rectangular connection frame 300 are installed on the rectangular window frame 100.

[0055] When the air pressure in the installation cavity 202 is greater than the external air pressure, since the connecting tube 450 connects the installation cavity 202 and the first cavity 402, and the second cavity 403 is connected to the outside, the pressure in the first cavity 402 is greater than the pressure in the second cavity 403. Under the action of the pressure difference between the first cavity 402 and the second cavity 403 and the action of the first spring 430, the piston 410 moves toward the second end of the installation cylinder 400, and the internal space of the first cavity 402 increases, thereby balancing the pressure in the installation cavity 202 and preventing the middle parts of the two flat glasses 201 from moving away from each other and deforming.

[0056] When the air pressure in the installation cavity 202 is lower than the external air pressure, the pressure in the first cavity 402 is lower than the pressure in the second cavity 403. Under the action of the pressure difference between the first cavity 402 and the second cavity 403 and the action of the second spring 440, the piston 410 moves toward the first end of the installation cylinder 400, and the internal space of the first cavity 402 is reduced, thereby balancing the pressure in the installation cavity 202 and preventing the middle parts of the two flat glasses 201 from approaching each other and deforming.

[0057] When the first spring 430 or the second spring 440 pushes the piston 410 to move, the push of the first spring 430 or the second spring 440 first deforms the rubber block 411, and the width of the rubber block 411 increases. After the rubber block 411 is deformed, it squeezes the rubber ring 412, thereby increasing the friction between the rubber ring 412 and the installation tube 400, so that the installation cavity 202 will not move until the pressure difference between the inside and outside of the installation cavity 202 reaches a preset size, thereby preventing the frequent movement of the piston 410 from causing excessive water vapor to enter the installation cavity 202 from the piston 410, thereby affecting the thermal insulation of the thermal insulation and energy-saving polymer resin doors and windows.

[0058] In the initial state, according to the different usage environments of the thermal insulation and energy-saving polymer resin doors and windows, the length of the adjusting ring 420 screwed into the second cavity 403 is adjusted. When the adjusting ring 420 is closer to the piston 410, the first spring 430 and the second spring 440 are more compressed, and the preload force of the first spring 430 and the second spring 440 is greater, which makes the piston 410 more difficult to move, so that the adjusting mechanism can balance the air pressure in the installation cavity 202 while preventing excessive water vapor from entering the installation cavity 202.

[0059] The water-absorbing rubber absorbs moisture in the second cavity 403 and the third cavity 413. When the external humidity is high, the water-absorbing rubber expands after absorbing water vapor. The expanded water-absorbing rubber squeezes the rubber block 411 and the rubber ring 412, thereby increasing the friction between the rubber ring 412 and the mounting cylinder 400, making the piston 410 more difficult to move.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
