Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy doors and windows, in particular to a combined aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows are doors and windows that use aluminum alloy as load-bearing rods and whose window structures are made of aluminum alloy. Because of their large window widths, large glass blocks, wide fields of view and high daylighting rates, they are the preferred option for people living in modern cities when decorating their mid- and high-rise buildings.

[0003] With people's continuous pursuit of higher living standards, rooms with sea view, lake view and landscape have emerged. While providing living value, they also provide residents with certain emotional value. When choosing windows, rooms with sea view, lake view and landscape generally choose large windows in order to see more scenery.

[0004] For some coastal areas, sea view rooms are a major feature. While houses near the seaside bring people more beautiful scenery, they also have to withstand greater wind pressure. Existing aluminum alloy doors and windows have a certain wind pressure resistance, but their wind pressure resistance is fixed. When the wind pressure level is greater than the wind pressure resistance level of the aluminum alloy doors and windows, the windows may be damaged due to the imbalance of pressure inside and outside the windows, especially the windows on the windward side of the sea view room. In more serious cases, they may fly off. After the windows fly off, they may injure the occupants or damage indoor items. If they fall from middle and high floors, they may also cause safety hazards to passers-by. For this reason, a combined aluminum alloy door and window is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a combined aluminum alloy door and window, which solves the problem that the existing aluminum alloy windows may be damaged or fly off due to unbalanced wind pressure when encountering a large wind pressure level. By utilizing a maximum wind pressure that exceeds the maximum wind pressure that the aluminum alloy window can withstand, the internal and external pressures of the aluminum alloy window can be balanced and the stability of the connection between the aluminum alloy frame and the wall can be increased.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A combined aluminum alloy door and window, comprising an aluminum alloy frame and an opening and closing mechanism, wherein the opening and closing mechanism is symmetrically distributed on the front side of the aluminum alloy frame;

[0008] The opening and closing mechanism includes an outer tube, an opening and closing rod, a guide groove, a guide column, a first return spring, a vent, an opening and closing control plate, a sleeve and a second return spring. The outer tube is symmetrically fixedly connected to the front side of the aluminum alloy frame in the upper and lower parts, the opening and closing rod is symmetrically arranged in the inner cavity of the outer tube, the vent is opened in the middle of the front side of the outer tube and is connected to the rear side of the aluminum alloy frame, and the two opening and closing rods are closed after the opposite sides are merged. The guide groove and the first return spring are evenly and staggeredly distributed on the outer wall of the outer tube. The guide column is located in the inner cavity of the guide groove and the rear end is fixedly connected to the opening and closing rod. The opening and closing control plate is fixedly connected to the guide column and the front end of the first return spring. The sleeve is located at the four corners of the outer side of the aluminum alloy frame and the position corresponds to the opening and closing rod. The second return spring is located in the inner cavity of the sleeve.

[0009] Existing aluminum alloy windows can only rely on their own wind pressure resistance when facing strong wind pressure. However, when the wind pressure is too high and far exceeds the wind pressure resistance of the window, the imbalance of pressure inside and outside the window makes it difficult to resist, and there is a risk of falling off. If a gap is left in advance to maintain pressure balance, it may cause strong winds to blow into the room, thereby damaging the indoor environment. In addition, for large-width landscape windows that cannot be opened and closed, when facing strong wind pressure, they can only rely on choosing higher-strength aluminum alloy profiles, regular inspection and maintenance, using wind-resistant hardware, and adjusting the thickness of the aluminum alloy window profiles. , wall thickness, column spacing and other optimizations to the window profile and design to improve the wind pressure resistance. However, the wind pressure level is difficult to control, and it will be difficult to resist when encountering greater wind pressure. This solution opens the vents to balance the pressure inside and outside the windows when the external wind pressure is greater than the wind pressure resistance level of the aluminum alloy doors and windows, and at the same time inserts the opening and closing rods into the wall to increase the stability of the windows to prevent the windows from being blown off by the external wind pressure. Compared with the single optimization of the aluminum alloy window profile and design, this solution can improve the wind pressure resistance of the aluminum alloy windows when facing greater wind pressure.

[0010] Preferably, the opening and closing control panel is arranged obliquely, and the oblique angle is specifically 10°-20°, and after the opening and closing control panel is rotated to the limit bottom end, a distance of 3-5 cm is set between the bottom and the aluminum alloy frame.

[0011] In the above scheme, the opening and closing control panel is set to an angle of 10°-20°. Compared with a flat setting, the opening and closing control panel can be driven to rotate more quickly under the action of wind pressure. If it is set in a flat plane, it may be difficult to complete the rotation due to the conflict between its own balance and the positive wind pressure. After the opening and closing control panel is rotated to the limit bottom end, the 3-5cm distance between the bottom and the aluminum alloy frame ensures that the opening and closing control panel will not collide with the aluminum alloy window when rotating, thereby avoiding collision damage under strong wind pressure.

[0012] Preferably, the sum of the initial tensions of the first return spring and the second return spring is equal to the value of level 9 positive wind pressure, and the initial tension of the second return spring is less than the initial tension of the first return spring.

[0013] In the above scheme, it is learned from the data that the wind pressure level that aluminum alloy windows can generally withstand is level 9, and the thermally-insulated aluminum alloy is about level 10. Level 9 is set as the critical value. When the positive wind pressure exceeds level 9, the wind pressure will be balanced. The initial tension of the second return spring is smaller than the first return spring, so that when the opening and closing control plate rotates to drive the opening and closing rod to slide, it will not cause movement interference with the opening and closing rod due to excessive initial tension.

[0014] Preferably, a through ventilation slot is provided in the middle of the front side of the aluminum alloy frame, the ventilation slot is connected to the ventilation port, and the thickness of the upper and lower ends of the aluminum alloy frame is greater than the thickness of the left and right ends.

[0015] In the above scheme, the connected ventilation slots and vents can ensure the balance of wind pressure inside and outside the aluminum alloy window, and limit the different thicknesses of the frame to ensure the overall strength of the aluminum alloy frame after the ventilation slots are opened.

[0016] Preferably, the rear side of the aluminum alloy frame is provided with a back baffle plate which is symmetrically arranged up and down, and the two back baffle plates are both arranged in an arc shape, and the openings of the two back baffle plates are opposite to each other.

[0017] In the above scheme, after the wind with positive wind pressure enters the room through the vents, the wind will be blocked by the two back baffles and move toward the two opposite openings, so that the wind force of the incoming positive wind pressure is offset, avoiding direct entry into the room to cause damage to indoor items.

[0018] Preferably, the outer walls of the two opening and closing rods at the opposite ends are both provided with arc-shaped limit strips, the inner cavity of the sleeve is provided with an arc-shaped limit groove matching the arc-shaped limit strip, and the arc-shaped limit strip and the guide groove have the same curvature and guide direction.

[0019] In the above scheme, when the positive wind pressure becomes smaller but has not completely disappeared, the engagement of the arc limit strip and the arc limit groove will have a buffering effect on the resetting of the opening and closing rod 202, thereby avoiding collision damage caused by repeated opening and closing of the opening and closing rod in a short period of time when the wind pressure is unstable. The arc limit strip and the guide groove have the same curvature and guiding direction to avoid motion interference, so that the arc limit strip and the arc limit groove can engage with each other following the guidance of the guide groove.

[0020] Preferably, the guide groove is arranged in an oblique arc shape, and the rotation angle of the guide groove is 45°-50°, and the lateral movement distance is 8-10 cm.

[0021] In the above scheme, the rotation angle and the lateral movement distance are limited to avoid excessive air intake and affect the indoor environment while ensuring ventilation.

[0022] Preferably, the bottom of the outer cylinder is provided with evenly distributed water guide holes, and the aluminum alloy frame and the glass assembly surface are arranged obliquely.

[0023] In the above scheme, a water guide hole is set at the bottom to avoid blockage of rainwater on rainy days, and the oblique setting of the assembly surface can prevent rainwater from accumulating on the window edge and easily penetrating into the sealing layer for a long time, causing damage to the sealing layer.

[0024] Preferably, an atrium is arranged in the middle of the aluminum alloy frame, and a central air guide groove and side air guide grooves are respectively arranged on the aluminum alloy frame and the left and right ends of the aluminum alloy frame, the central air guide groove is arranged in a "Y" shape, the side air guide groove is arranged in an "L" shape, and the air outlets of the central air guide groove and the side air guide groove are arranged relatively.

[0025] In the above scheme, part of the positive wind can be guided by opening the central air guide groove and the side air guide groove, so that it can be blown horizontally on the glass surface, thereby removing the dust stains remaining on the glass and reducing the residual dust stains. In addition, when facing a large positive wind pressure, the wind rushing against the glass surface will resist the pressure of the positive wind pressure and buffer it, thereby reducing the pressure of the positive wind pressure on the glass.

[0026] Preferably, the thickness of the atrium is 1.5-2 times that of the left and right ends of the aluminum alloy frame, and the distance between the air outlets of the central air guide groove and the side air guide groove and the glass is 2-3 cm.

[0027] In the above scheme, the thickness of the atrium is used to ensure the strength of the middle part of the aluminum alloy frame. The distance between the air outlet of the middle air guide groove and the side air guide groove and the glass is 2-3 cm to ensure that the lateral wind can clean the glass facade and avoid insufficient installation strength of the glass due to too close distance.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. When the aluminum alloy window in the present invention faces a wind pressure exceeding the maximum tolerable wind pressure, the wind pressure drives the opening and closing control panel to rotate and move laterally, thereby driving the connected opening and closing rods to move synchronously, so that the vents are opened when the two opening and closing rods move, allowing wind to enter the room through the vents, thereby balancing the pressure on the outside and inside of the aluminum alloy window, avoiding loosening and damage due to unbalanced pressure on both sides, so that the aluminum alloy window can withstand higher levels of wind pressure on the basis of its own wind pressure resistance level, and is more suitable for areas near the sea with unstable wind pressure.

[0030] 2. When the opening and closing rods of the present invention move in opposite directions, their opposite ends will be inserted into the matching sleeves, and the sleeves will be fixed in the wall, thereby increasing the connection stability between the aluminum alloy frame and the wall. When facing strong wind pressure, the aluminum alloy frame can be prevented from loosening and falling off, thereby damaging objects or injuring people.

[0031] 3. The present invention guides the wind entering the room through the back baffle and offsets the wind force through convection between the upper and lower winds. Compared with allowing the wind to enter the room directly, it can effectively prevent the direct wind from causing damage to indoor items, and effectively protect indoor items and people while balancing the wind pressure inside and outside the window.

DETAILED DESCRIPTION

[0044] The following is a more clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, and the described embodiments are only a part of all the embodiments of the present invention. Based on the embodiments of the present invention, all embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0045] See also Figures 1 to 9 The present invention provides a combined aluminum alloy door and window, and the technical solution is as follows:

[0046] A combined aluminum alloy door and window, comprising an aluminum alloy frame 100 and an opening and closing mechanism 200, wherein the opening and closing mechanism 200 is symmetrically distributed on the front side of the aluminum alloy frame 100;

[0047] The opening and closing mechanism 200 includes an outer cylinder 201, an opening and closing rod 202, a guide groove 203, a guide column 204, a first return spring 205, a vent 207, an opening and closing control panel 208, a sleeve 211 and a second return spring 212. The outer cylinder 201 is fixedly connected to the front side of the aluminum alloy frame 100 symmetrically from top to bottom, and the opening and closing rod 202 is slidably connected to the inner cavity of the outer cylinder 201 symmetrically from left to right. The vent 207 is opened in the middle of the front side of the outer cylinder 201 and is connected to the rear side of the aluminum alloy frame 100. Therefore, when the vent 207 is connected, the external wind force can enter the interior of the aluminum alloy window to ensure The balance of the internal and external pressures of the aluminum alloy doors and windows can prevent the aluminum alloy doors and windows from being damaged or falling off due to excessive external wind pressure. The two opening and closing rods 202 are combined on the opposite sides to close the vent 207, thereby ensuring the sealing of the aluminum alloy windows themselves when the wind pressure level is low. The guide grooves 203 and the first return springs 205 are evenly and staggeredly distributed on the outer wall of the outer tube 201. The guide grooves 203 run through the front side of the outer tube 201. The guide column 204 is located in the inner cavity of the guide grooves 203 and the rear end is fixedly connected to the opening and closing rods 202. The opening and closing control panel 208 is fixedly connected to the guide column 204 and the first return spring The front end of the spring 205, the sleeve 211 is located at the four corners of the outer side of the aluminum alloy frame 100 and the position corresponds to the opening and closing rod 202, and the second return spring 212 is located in the inner cavity of the sleeve 211. When the external positive wind pressure level is greater than the initial tension of the first return spring 205 and the second return spring 212, the two opening and closing control plates 208 will rotate with the pressure of the positive wind pressure, and when the opening and closing control plates 208 rotate, the guide column 204 connected thereto is limited by the guide groove 203, so that the two opening and closing control plates 208 move in opposite directions at the same time when rotating. When the control panel 208 moves, the opening and closing rod 202 connected to the opening and closing control panel 208 through the guide column 204 will rotate and move synchronously with the opening and closing control panel 208, so that the opposite ends of the two opening and closing rods 202 open, and the vents 207 also open accordingly, so that the external wind enters the room through the vents 207, thereby balancing the pressure inside and outside the aluminum alloy window, and when the two opening and closing rods 202 move away from each other, the two opposite ends enter the sleeve 211, thereby increasing the connection stability between the aluminum alloy frame 100 and the wall, and preventing the wind pressure from blowing off the aluminum alloy frame 100.

[0048] As an embodiment of the present invention, refer to Figure 4 , 6The opening and closing control panel 208 is set obliquely, and the specific oblique angle is 10°-20°. After the opening and closing control panel 208 is rotated to the limit bottom end, the bottom is set 3-5cm away from the aluminum alloy frame 100. Compared with the flat setting, the oblique opening and closing control panel 208 can drive the opening and closing control panel 208 to rotate more quickly under the action of wind pressure; the added value of the initial tension of the first return spring 205 and the second return spring 212 is equal to the pressure value of the 9th level positive wind pressure, and the initial tension of the second return spring 212 is less than the initial tension of the first return spring 205. When the positive wind pressure exceeds 9 levels, the vent 207 will be opened to balance the wind pressure.

[0049] As an embodiment of the present invention, refer to Fig. 9 A through ventilation slot 209 is provided in the middle of the front side of the aluminum alloy frame 100, and the ventilation slot 209 is connected with the vent 207. The thickness of the upper and lower ends of the aluminum alloy frame 100 is greater than the thickness of the left and right ends. The connected setting can achieve the balance of wind pressure, thereby avoiding damage to the aluminum alloy window caused by excessive external wind pressure; a back baffle 210 symmetrically arranged up and down is fixedly connected to the rear side of the aluminum alloy frame 100, and the two back baffles 210 are both arc-shaped, and the openings of the two back baffles 210 are opposite to each other. When the wind enters the back of the aluminum alloy window through the vent 207 and the ventilation slot 209, it will be blocked by the two back baffles 210 and move to the opposite opening, so that the two relative winds will offset each other, avoiding the wind directly entering the room from causing damage to indoor items.

[0050] As an embodiment of the present invention, refer to Figure 1 , 27. The outer walls of the opposite ends of the two opening and closing rods 202 are fixedly connected with an arc-shaped limit strip 206. The inner cavity of the sleeve 211 is provided with an arc-shaped limit groove 213 that matches the arc-shaped limit strip 206. The arc-shaped limit strip 206 and the guide groove 203 have the same curvature and guide direction. When the positive wind pressure decreases but does not completely disappear, the force of the positive wind pressure and the rebound force of the first return spring 205 and the second return spring 212 resist each other, so that the opening and closing rod 202 cannot be completely rotated. As a result, the arc-shaped limit strip 206 cannot be completely disengaged from the arc-shaped limit groove 213, thereby buffering the reset of the opening and closing rod 202. When the positive wind pressure is completely less than the first return spring 205 and the second return spring When the spring 212 has a rebound force, the arc-shaped limit strip 206 will come out of the arc-shaped limit groove 213 as the opening and closing rod 202 rotates; the guide groove 203 is set in an oblique arc shape, and the rotation angle of the guide groove 203 is 45°-50°, and the lateral movement distance is 8-10cm. The rotation angle and lateral movement distance of the guide groove 203 are limited to ensure ventilation while avoiding excessive air intake and causing impact on the room; the bottom of the bottom outer cylinder 201 is provided with evenly distributed water guide holes 214, and the aluminum alloy frame 100 and the glass assembly surface are set obliquely; the water guide holes 214 and the oblique setting are both used to clear rainwater to avoid rainwater accumulation and damage to the sealing layer at the joints of the aluminum alloy windows.

[0051] As an embodiment of the present invention, refer to Figure 3 , 5 8. The middle of the aluminum alloy frame 100 is fixedly connected with an atrium 101. The aluminum alloy frame 100 and the left and right ends of the aluminum alloy frame 100 are respectively provided with a central air guide groove 103 and a side air guide groove 102. The central air guide groove 103 is set in a "Y" shape, and the side air guide groove 102 is set in an "L" shape. The air outlets of the central air guide groove 103 and the side air guide groove 102 are arranged oppositely. The thickness of the atrium 101 is 1.5-2 of the left and right ends of the aluminum alloy frame 100. times, the air outlets of the central air guide groove 103 and the side air guide groove 102 are 2-3cm away from the glass. When facing the positive wind, the central air guide groove 103 and the side air guide groove 102 will guide part of the wind to blow it horizontally on the glass surface, so as to clean the dust stains on the glass surface, and the two relative horizontal winds will buffer the positive wind pressure blowing toward the glass, thereby reducing the pressure of the positive wind pressure on the glass and providing side protection for the glass.

[0052] Working principle: This solution balances the pressure on the outside and inside of aluminum alloy windows by ventilating them when they face a wind pressure level that exceeds their tolerance limit, thus preventing them from being damaged or even falling off due to pressure imbalance. At the same time, the possibility of falling off is reduced by increasing the stability of the connection between the frame and the wall. The specific methods are as follows:

[0053] The installation position of the aluminum alloy window is normally in the direction of positive wind pressure, and when installing, it is necessary to punch holes in the corresponding position of the installation frame of the aluminum alloy window in advance, and the punching position corresponds to the position of the opening and closing rod 202. After the punching is completed, the sleeve 211 is fixed in the hole by cement or other fixing methods, and then the aluminum alloy window can be installed according to the normal aluminum alloy window installation method;

[0054] When facing the wind pressure that the aluminum alloy window can withstand, the two opening and closing rods 202 abut against each other to block the vent 207, so that it maintains airtightness, thereby achieving the same sealing, sound insulation and heat preservation functions as the existing aluminum alloy windows;

[0055] When facing the wind pressure that the aluminum alloy window cannot bear, that is, the positive wind pressure of more than level 9, the two opening and closing control plates 208 will rotate with the pressure of the positive wind pressure, and when the opening and closing control plates 208 rotate, the guide column 204 connected thereto is limited by the guide groove 203, so that the two opening and closing control plates 208 move in opposite directions at the same time when rotating. When the two opening and closing control plates 208 move, the opening and closing rods 202 connected to the opening and closing control plates 208 through the guide column 204 will rotate and move synchronously with the opening and closing control plates 208, so that the opposite ends of the two opening and closing rods 202 are opened, and the vents 207 are also opened accordingly, so that the external wind force enters the room through the vents 207, thereby balancing the pressure inside and outside the aluminum alloy window. After the wind enters the room, it is first blocked by the two back baffles 210 and moves toward the opposite opening, so that the two opposite winds will offset each other, avoiding the wind that directly enters the room from causing damage to indoor items.

[0056] When the two opening and closing rods 202 move in opposite directions, the two opposite ends enter the sleeve 211, thereby increasing the connection stability between the aluminum alloy frame 100 and the wall, and preventing the aluminum alloy frame 100 from being blown off by wind pressure, thereby falling and damaging objects or injuring people;

[0057] When the positive wind blows toward the window, part of the wind will be diverted by the central wind guide groove 103 and the side wind guide groove 102, so that the wind blows laterally on the glass surface. The two relative lateral winds will buffer the positive wind pressure blowing toward the glass, thereby reducing the pressure of the positive wind pressure on the glass and providing side protection for the glass.

[0058] The main advantages and working principles of the embodiments of the present invention have been explained above. Then, as a person skilled in the art, it should be understood that the above embodiments are not intended to be limiting conditions of the present invention. Various changes, modifications, substitutions and variations may be made without departing from the principles, spirit and scope of the invention. These changes, modifications, substitutions and variations should all fall within the scope of protection of the present invention.
