[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0020] When it rains, some rainwater will accumulate at the bottom of the window frame along the window frame. Since the rainwater may contain dust and other foreign matter, these foreign matter may affect the drainage efficiency of the drainage hole. When the window needs to be opened, the rainwater accumulated at the bottom of the window frame may flow back into the room, thereby polluting the indoor environment and possibly affecting the normal work of indoor staff.
[0021] In view of this, the utility model provides a noise-reducing and sound-insulating aluminum alloy window. The noise-reducing and sound-insulating aluminum alloy window prevents rainwater accumulated at the bottom of the window frame from flowing back into the room through the cooperation of a drainage trough, a filter screen, a blocking plate, a retaining spring and a limit rod, thereby improving the drainage effect of the noise-reducing and sound-insulating aluminum alloy window, not only ensuring that the indoor environment will not be polluted by rainwater, but also ensuring that the normal work of indoor staff will not be affected by the backflow of rainwater.
[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.
[0023] Example 1: By Figure 1-5 As can be seen, a noise-reducing and sound-insulating aluminum alloy window includes a window frame 1, a sash frame 2 is provided inside the window frame 1, and a glass 21 is provided inside the sash frame 2. There are two glasses 21, a PVB film 22 is fixedly connected between the two glasses 21, and a sealing strip 23 is fixedly connected to the side of the outer wall of the two glasses 21 away from the PVB film 22. The bottom of the sealing strip 23 is fixedly connected to the outer wall of the sash frame 2. The noise-reducing and sound-insulating aluminum alloy window also includes a drainage structure 3, a sealing structure 4 and a sound insulation structure 5. The drainage structure 3 is provided at the bottom of the inner wall of the window frame 1; the sealing structure 4 is provided between the PVB film 22 and the sash frame 2; the sound insulation structure 5 is provided on the side of the outer wall of the sash frame 2 close to the window frame 1; wherein, the drainage structure 3 prevents rainwater accumulated in the window frame 1 from flowing back into the room, the sealing structure 4 prevents water vapor from entering the interlayer of the two glasses 21, and the sound insulation structure 5 improves the sound insulation effect of the aluminum alloy window;
[0024] During the specific implementation process, it is worth noting that the noise reduction and sound insulation aluminum alloy window is a casement window. The window frame 1 is rectangular as a whole and is rotatably connected to the sash frame 2 through a hinge. A handrail is provided on the side of the outer wall of the sash frame 2 away from the hinge to assist indoor personnel in opening or closing the aluminum alloy window. The inner wall of the sash frame 2 is provided with a "bow"-shaped groove. The glass 21 is a single-layer glass 21, and a groove with a rectangular cross-section is provided at its bottom. The groove and the groove on the inner wall of the sash frame 2 can be snapped together to fix the two glasses 21, thereby ensuring the structural stability of the noise reduction and sound insulation aluminum alloy window. A PVB film 22 is provided between the two glasses 21. The PVB film 22 can be selected from a 1.52mm thick automotive-grade film. The sealing strip 23 surrounds the inner wall of the sash frame 2 and can be made of EPDM rubber to ensure the sealing effect of the noise reduction and sound insulation aluminum alloy window.
[0025] Furthermore, the drainage structure 3 includes a drainage groove 31, a filter 32, a baffle 33, a retaining spring 34, and a limiting rod 35. The drainage groove 31 is opened at the bottom of the inner wall of the window frame 1; the filter 32 is arranged at the end of the drainage groove 31 and is fixedly connected to the outer wall of the window frame 1; the baffle 33 is arranged inside the drainage groove 31 and is located below the sash frame 2; the retaining spring 34 is fixedly connected to the inner wall of the drainage groove 31, and its end is pressed against the side of the outer wall of the baffle 33 away from the sash frame 2; the limiting rod 35 is inserted into the inner wall of the retaining spring 34 and fixedly connected to the inner wall of the drainage groove 31. The cooperation of the drainage groove 31, the filter 32, the baffle 33, the retaining spring 34, and the limiting rod 35 prevents rainwater accumulated in the window frame 1 from flowing back into the room.
[0026] In the specific implementation process, it is worth noting that the cross-section of the drainage groove 31 is rectangular and is arranged at the bottom of the inner wall of the sash frame 2. The overall shape is similar to a rectangular strip. The length of the filter 32 is the same as that of the drainage groove 31. The filter 32 is fixed to the outer wall of the window frame 1 by bolts. The filter 32 prevents foreign objects from entering the outside of the drainage groove 31. Its material can be stainless steel and its aperture can be 1mm. The cross-section of the blocking plate 33 is similar to the shape of a '4' and its material can be plastic. Its length is the same as that of the drainage groove 31. The retaining spring 34 can be made of 65Mn spring steel. The specific elastic coefficient can be selected according to actual needs to meet the work. The limiting rod 35 is a cylindrical rod with the same length as the drainage groove 31 to limit the retaining spring 34. When the indoor personnel need to open the window after raining, first, the indoor personnel pull the handrail to open the window. When the window is closed, the window frame 1 drives the sound insulation structure 5 to return to its original position, and the sound insulation structure 5 pushes the baffle plate 33, which squeezes the retaining spring 34, and the baffle plate 33 returns to its original position, and the drain groove 31 is closed. At this time, the window is also closed, and the cooperation of the drain groove 31, the filter screen 32, the baffle plate 33, the retaining spring 34 and the limiting rod 35 prevents the rainwater stored in the window frame 1 from flowing back into the room, thereby improving the drainage capacity of the aluminum alloy window with noise reduction and sound insulation.
[0027] Furthermore, a drainage hole 11 is provided on the side of the inner wall of the window frame 1 away from the drainage groove 31;
[0028] In the specific implementation process, it is worth noting that a plurality of drainage holes 11 are provided, each of which has a rectangular cross-section and a baffle fixedly connected to the end thereof to prevent foreign matter from blocking the end of the drainage hole 11, thereby ensuring the basic drainage effect of the noise-reducing and sound-insulating aluminum alloy window;
[0029] Example 2: By Figure 1-5 As can be seen, the sealing structure 4 includes a sealing ring 41, a shape memory alloy wire 42, and a sealing gasket 43. The sealing ring 41 is arranged between the two glass panes 21 and is sleeved on the outer wall of the PVB film 22. The shape memory alloy wire 42 is inserted into the inner wall of the sealing ring 41. The sealing gasket 43 is fixedly connected to the inner wall of the sash frame 2, with its top affixed to the glass panes 21, the sealing strip 23, and the bottom of the sealing ring 41. The cooperation of the sealing ring 41, the shape memory alloy wire 42, and the sealing gasket 43 prevents moisture from entering the interlayer between the two glass panes 21.
[0030] During the specific implementation process, it is worth noting that the sealing ring 41 surrounds the PVB film 22. The material of the sealing ring 41 can be silicone. A shape memory alloy wire 42 with a diameter of 0.5 mm is embedded inside. The phase change temperature is set to 25°C. Its material can be nickel-titanium. The process of realizing the shape memory effect is as follows: in the low-temperature deformation stage, the alloy wire is in a martensite state at a temperature below M_f. External force (such as bending and stretching) is applied to deform it. At this time, the twin boundaries move, and the crystal structure is rearranged but the atomic bonds are not destroyed; in the temperature triggering stage, when the ambient temperature exceeds A_s, the martensite begins to reverse phase transformation into austenite, and the atoms return to the initial crystal structure through diffusionless shear (only the atomic position is adjusted, without changing the composition); in the shape recovery stage, the temperature rises above A_f, and it is completely transformed into austenite. The atomic arrangement returns to the "memory state", overcoming the external constraint force, generating a recovery force and restoring the original shape. The shape of the sealing gasket 43 is exactly the same as the shape of the inner wall of the fan frame 2, and EPDM can be used. The composite material of rubber and butyl rubber, in actual use, when a large temperature difference causes the sealing ring 41 to shrink, the shape memory alloy wire 42 is heated and expands, pushing the sealing ring 41 to restore its shape, preventing the formation of gaps. Through the cooperation of the sealing ring 41, the shape memory alloy wire 42 and the sealing gasket 43, the sealing performance of the noise reduction and sound insulation aluminum alloy window is improved;
[0031] Furthermore, the sound insulation structure 5 includes a first rubber ring 51, a second rubber ring 52, and a rubber seat 53. The first rubber ring 51 is fixedly connected to the inner wall of the window frame 1 on a side near the drain hole 11, and the outer wall of the window frame 1 is affixed to the outer wall of the sash frame 2 on a side away from the window frame 1. The second rubber ring 52 is fixedly connected to the outer wall of the sash frame 2 on a side near the drain groove 31. The rubber seat 53 is tightly pressed against the top of the blocking plate 33, affixed to the outer wall of the sash frame 2, and fixedly connected to the outer wall of the second rubber ring 52. The cooperation of the first rubber ring 51, the second rubber ring 52, and the rubber seat 53 improves the sound insulation effect of the aluminum alloy window.
[0032] During the specific implementation process, it is worth noting that the shape of the first rubber ring 51 is similar to the window frame 1, and its material can be selected from neoprene. The shape and material of the first and second rubber rings 51 and 52 are the same, but the installation positions are different. The rubber seat 53 is made of polyurethane elastomer and can be filled with sound-absorbing cotton to block the sound transmission path between the drainage groove 31 and the room. The rubber seat 53 also serves as a limiter for the blocking plate 33. When the window is closed, the rubber seat 53 squeezes the blocking plate 33, and the blocking plate 33 squeezes the retaining spring 34. At this time, the blocking plate 33 closes the drainage groove 31, forming a dual function of "sealing + sound absorption". Through the cooperation of the first rubber ring 51, the second rubber ring 52 and the rubber seat 53, the sound insulation effect of the noise-reducing and sound-insulating aluminum alloy window is improved.
[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
