Description
Technical Field
[0001] The utility model relates to the technical field of door and window installation, in particular to a rain and wind proof automatic closing device for aluminum alloy doors and windows. Background Art
[0002] During the traditional production process of aluminum alloy, drain holes for draining rainwater are milled at the outer middle stile or frame of aluminum alloy windows. After on-site installation, there are usually two situations. In some cases, the drain holes are directly exposed, and in some cases, wind-proof blocks are installed to cover the drain holes. However, in both cases, it is inevitable that rainwater will backflow under the action of wind pressure, and the effect of timely draining the rainwater falling into the aluminum alloy window frame cannot be achieved.
[0003] The existing design of drain holes in aluminum alloy doors and windows has the technical problem that it cannot effectively prevent rainwater backflow caused by wind pressure because it is always connected to the outside. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a rain and wind proof automatic closing device for aluminum alloy doors and windows to solve the technical problem in the related art that it cannot effectively prevent rainwater backflow caused by wind pressure because it is always connected to the outside.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows:
[0006] The rain and wind proof automatic closing device provided by the utility model includes:
[0007] A rain-proof shell, a wind shield and a reset function member. The rain-proof shell is installed on the window frame and covers the drain hole, and the rain-proof shell is provided with a water discharge port communicated with the drain hole. The wind shield is movably connected to the rain-proof shell, and the reset function member drives the wind shield to close the water discharge port. The rainwater discharged from the drain hole drives the wind shield to open the water discharge port.
[0008] Specifically, the rain-proof shell is provided with a rotating shaft, and the wind shield is rotatably connected to the rotating shaft for opening and closing the water discharge port.
[0009] Specifically, the wind shield is provided with a water accumulation groove for storing the water discharged from the drain hole. The wind shield drives the wind shield to swing in the direction of opening the water discharge port by the gravity of the rainwater in the water accumulation groove.
[0010] Specifically, the reset function member is installed on the wind shield and is used to apply a force to the wind shield to drive the wind shield to swing in the direction of closing the water discharge port. When the torque generated by the gravity of the rainwater in the water accumulation groove is less than the torque generated by the force applied by the reset function member, the wind shield swings in the direction of closing the water discharge port.
[0011] Specifically, the rainproof shell is provided with a limiting stop, and the limiting stop is used to limit the swinging angle of the wind deflector in the direction of closing the water discharge port. The reset function member can drive the wind deflector to swing in the direction of closing the water discharge port and keep the water discharge port in a closed state.
[0012] Specifically, it further includes a limit pin, and the limit pin is installed on the rainproof shell. When the gravity of the rainwater in the water accumulation tank exceeds the force applied by the reset function member, the wind deflector swings in the direction of opening the water discharge port and abuts against the limit pin to limit the swinging angle of the wind deflector in the direction of opening the water discharge port.
[0013] Specifically, the reset function member is set as a counterweight, and the gravity of the counterweight is used to drive the wind deflector to swing in the direction of closing the water discharge port.
[0014] Specifically, the reset function member is set as a spring. One end of the spring is connected to the rainproof shell, and the other end is connected to the wind deflector. The elastic force of the spring is used to drive the wind deflector to swing in the direction of closing the water discharge port.
[0015] Specifically, the wind deflector, the rotating shaft, the reset function member and the limit pin are all symmetrically provided with mirror images with respect to the middle cross-section of the rainproof shell in the length direction.
[0016] Specifically, the rainproof shell fits on the window frame. The rainproof shell is further provided with a protrusion, and the protrusion is snap-fitted into the drain hole.
[0017] Based on the above technical solutions, the beneficial effects of the present utility model are analyzed as follows:
[0018] The present utility model provides a wind and rainproof automatic closing device for aluminum alloy doors and windows, including:
[0019] A rainproof shell, a wind deflector and a reset function member. The rainproof shell is installed on the window frame and covers the drain hole, and the rainproof shell is provided with a water discharge port communicated with the drain hole. The wind deflector is movably connected to the rainproof shell, and the reset function member drives the wind deflector to close the water discharge port. The rainwater discharged from the drain hole drives the wind deflector to open the water discharge port.
[0020] During specific application, the installation position needs to be determined first, and the drain hole is completely covered with the rainproof shell. In the initial state without rain, the water discharge port is in a closed state to prevent dust from being blown into the window frame. When the rainwater in the window frame flows to the wind deflector through the drain hole, the wind deflector opens the water discharge port under the gravity of the rainwater. After the rainwater is quickly discharged, the wind deflector re-closes the water discharge port under the action of the reset function member to avoid rainwater being backflowed from the water discharge port driven by the wind pressure.
[0021] It can be seen that, compared with the prior art, the rainproof and windproof automatic closing device realizes the drain opening that can be automatically closed through the wind baffle and the reset function member, avoiding the long-term connection between the drain opening and the outside world, and overcoming the technical problem existing in the design of the drainage holes of the existing aluminum alloy doors and windows that the rainwater backflow caused by the wind pressure cannot be effectively prevented due to the continuous connection with the outside world at all times.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0038] The following will describe in detail some implementation manners of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0039] There is a technical problem in the existing design of drainage holes in aluminum alloy doors and windows that rainwater backflow caused by wind pressure cannot be effectively prevented because they are always connected to the outside.
[0040] In view of this, the present utility model provides a wind and rain automatic closing device for aluminum alloy doors and windows, including:
[0041] A rainproof shell 100, a windshield 200, and a reset function member 300. The rainproof shell 100 is installed on the window frame 001 and covers the drainage hole 002. The rainproof shell 100 is provided with a water discharge port 101 communicating with the drainage hole 002. The windshield 200 is movably connected to the rainproof shell 100, and the reset function member 300 drives the windshield 200 to close the water discharge port 101. The rainwater discharged from the drainage hole 002 drives the windshield 200 to open the water discharge port 101.
[0042] Based on the above technical solutions, the wind and rain automatic closing device provided by the present utility model can achieve the following technical effects:
[0043] The weatherproof automatic closing device realizes the automatically closable water drain port 101 through the wind baffle 200 and the reset function member 300, avoiding the long-term connection between the drain hole 002 and the outside world, and overcoming the technical problem existing in the existing drain hole design of aluminum alloy doors and windows that rainwater backflow caused by wind pressure cannot be effectively prevented due to the continuous connection with the outside world all the time.
[0044] The following will combine Figures 1 to 7 to detail the structure and shape of the weatherproof automatic closing device provided in this embodiment:
[0045] In the solution of this embodiment, as Figure 2 shown, the rainproof shell 100 fits on the window frame 001. The rainproof shell 100 is also provided with a protrusion 130, and the protrusion 130 is clamped to the drain hole 002.
[0046] In the solution of this embodiment, as Figure 6 shown, the rainproof shell 100 is provided with a rotating shaft 110, and the wind baffle 200 is rotatably connected to the rotating shaft 110 for opening and closing the water drain port 101. In a rainless state, the water drain port 101 is in a closed state to prevent external dust from entering. In a rainy state, the wind baffle 200 rotates to open the water drain port 101 for drainage, and after the drainage is completed, the water drain port 101 is re-closed to restore the closed state of the water drain port 101.
[0047] In the solution of this embodiment, as Figure 5 shown, one end of the wind baffle 200 is provided with a water accumulation groove 210, and the water accumulation groove 210 is used to store the water discharged from the drain hole 002. The wind baffle 200 is driven by the gravity of the rainwater in the water accumulation groove 210 to swing in the direction of opening the water drain port 101.
[0048] Regarding how the automatic closing function of the reset function member 300 is realized, specifically:
[0049] The reset function member 300 is installed at one end of the wind baffle 200 away from the water accumulation groove 210, and is used to apply a force to the wind baffle 200 to drive the wind baffle 200 to swing in the direction of closing the water drain port 101. When the torque generated by the gravity of the rainwater in the water accumulation groove 210 is less than the torque generated by the force applied by the reset function member 300, the wind baffle 200 swings in the direction of closing the water drain port 101. When the torque generated by the gravity of the rainwater in the water accumulation groove 210 is greater than the torque generated by the force applied by the reset function member 300, the wind baffle 200 swings in the direction of opening the water drain port 101.
[0050] In order to make the windshield 200 swing towards the direction of closing the drain opening 101 and then be stable horizontally so that the drain opening 101 remains in the closed state, in the solution of this embodiment, the rainproof shell 100 is provided with a limit stop 120, and the limit stop 120 is used to limit the swing angle of the windshield 200 towards the direction of closing the drain opening 101. The reset function member 300 can drive the windshield 200 to swing towards the direction of closing the drain opening 101 and keep the drain opening 101 in the closed state.
[0051] In order to prevent the swing of the windshield 200 towards the direction of opening the drain opening 101 from exceeding the maximum allowable angle designed, resulting in the failure of the reset function, in the solution of this embodiment, as Figure 7 shown, the rainproof and automatic closing device further includes a limit pin 400, and the limit pin 400 is installed on the rainproof shell 100. When the gravity of the rainwater in the water collecting tank 210 exceeds the force exerted by the reset function member 300 and the windshield 200 swings towards the direction of opening the drain opening 101 to the maximum allowable angle designed, the windshield 200 will abut against the limit pin 400 to limit the swing angle of the windshield 200 towards the direction of opening the drain opening 101.
[0052] In an alternative solution of this embodiment, as Figure 6 shown, the reset function member 300 is set as a counterweight 310 and is installed at one end of the windshield 200 away from the water collecting tank 210, and the gravity of the counterweight 310 is used to drive the windshield 200 to swing towards the direction of closing the drain opening 101 so that the drain opening 101 remains in the closed state.
[0053] In an alternative solution of this embodiment, the reset function member 300 is set as a spring. One end of the spring is connected to the rainproof shell 100, and the other end is connected to one end of the windshield 200 away from the water collecting tank 210. When the torque generated by the gravity of the rainwater in the water collecting tank 210 is greater than the torque generated by the elastic force of the spring, the windshield 200 swings towards the direction of opening the drain opening 101, and the spring is compressed accordingly. When the rainwater in the water collecting tank 210 is discharged through the drain opening 101, the torque generated by the gravity of the rainwater in the water collecting tank 210 is less than the torque generated by the elastic force of the spring in the compressed state at this time, and the thrust of the spring drives the windshield 200 to swing towards the direction of closing the drain opening 101.
[0054] In order to optimize the drainage efficiency and drainage pressure distribution of the windshield 200, in the solution of this embodiment, as Figure 6As shown, the wind deflector 200, the rotating shaft 110, the reset function member 300, and the limit pin 400 are all symmetrically provided with mirror members with respect to the mid-section of the rainproof housing 100 in the length direction. After the length of the wind deflector 200 is reduced, as an independent unit, it is respectively used to open and close half of the range of the water discharge port 101. Each independent unit responds quickly and flexibly to local rainwater accumulation, achieving more frequent small-scale drainage without the entire device accumulating a certain amount of water. This decentralized drainage reduces the load of single drainage, reduces the overall pressure during drainage, and at the same time improves the flexibility and efficiency of the device in the face of a large amount of rain, enhancing the drainage efficiency and reliability.
[0055] In the solution of this embodiment, the rainproof housing 100, the wind deflector 200, the reset function member 300, and the limit pin 400 are all made of PVC material. PVC has excellent water resistance, chemical resistance, weather resistance, and stability, and can maintain stable performance under various climate conditions.
[0056] In summary, the specific working process of the wind and rain automatic closing device provided in this embodiment is as follows:
[0057] Taking the reset function member 300 set as the counterweight 310 as an example.
[0058] During installation, the protrusion 130 of the rainproof housing 100 is snapped into the pre-milled drainage hole 002 of the window frame 001. The wind deflector 200 can open and close the water discharge port 101 by rotating around the rotating shaft 110.
[0059] In the case of no rain, one end of the wind deflector 200 abuts against the limit stop 120 under the drive of the counterweight 310, the wind deflector 200 is in a horizontal state, and the water discharge port 101 is closed to prevent dust from being blown into the window frame 001.
[0060] In the case of rain, when the rainwater in the window frame 001 flows to the wind deflector 200, the water collecting groove 210 on the wind deflector 200 plays a role in collecting water. When the torque generated by the gravity of the rainwater is greater than the torque generated by the gravity of the counterweight 310 on the other side of the rotating shaft 110, the wind deflector 200 opens under the action of the gravity of the rainwater, playing a role in draining water. One end of the wind deflector 200 abuts against the limit pin 400 under the action of the gravity of the rainwater.
[0061] After the rainwater in the water collecting groove 210 is quickly discharged, since the torque generated by the gravity of the counterweight 310 is greater than the torque generated by the gravity of the rainwater, the wind deflector 200 re-closes the water discharge port 101 under the action of the gravity of the counterweight 310 to prevent rainwater from flowing back from the water discharge port 101 driven by the wind pressure.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
