Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, in particular to a windproof drainage hole cover and a door and window. Background Art

[0002] In architectural design, doors and windows mainly play the role of lighting and ventilation. For doors and windows installed on the exterior walls, when it rains, rainwater often accumulates in the window frames. Especially in extreme weather conditions with strong winds, the high pressure outside makes it difficult for the accumulated water in the window to be discharged smoothly, and it may even flow back into the room, causing the indoor environment to be humid, and even corroding the hardware accessories of the doors and windows, seriously affecting the normal use of the doors and windows. In order to deal with this problem, it is proposed in the prior art to install windproof drain hole covers at the drain holes of doors and windows. The windproof drain hole covers can not only have the function of drainage, but also effectively prevent airflow from flowing into the drain holes of doors and windows.

[0003] However, the windproof drain hole covers commonly used in the market currently mostly adopt the design of pivot type windproof pieces. Affected by the rotational freedom of the pivot type windproof pieces, a tiny gap is easily generated between the pivot type windproof pieces and the drain holes. At the same time, the windproof drain hole covers and the profiles are mostly connected in a snap-on form, which leaves snap-on gaps after the windproof drain hole covers are installed. These gaps weaken the sealing effect to a certain extent, thereby reducing the windproof and insect-proof functions. Moreover, after the windproof drain hole covers are installed, they are prone to falling off during transportation. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0035] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0036] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] like Figure 1 As shown, Figure 1 It is a cross-sectional view of the drainage hole cover installation structure of the rotating shaft windproof sheet 10 in the prior art. It can be seen from the figure that the rotating shaft windproof sheet 10 in the prior art is affected by the rotational freedom, and a small gap 11 is easily generated between the rotating shaft windproof sheet 10 and the drainage hole. Under normal circumstances, this gap 11 is caused by the water flow pressure in the door and window drainage hole being pushed open. However, in certain special cases, for example, the rotating shaft windproof sheet 10 is affected by gravity and cannot completely fit the drainage hole, and the gap 11 continues to exist. At the same time, since the windproof drainage hole covers on the market are mostly connected to the door and window profiles 30 in a snap-fit ​​form, a snap-fit ​​gap 12 is left between the windproof drainage hole cover and the door and window profiles 30 after installation. The existence of the gap 11 and the snap-fit ​​gap 12 weakens its sealing effect to a certain extent, thereby weakening the windproof and insect-proof functions; and after the windproof drainage hole cover is installed, it is easy to fall off during transportation. For this reason, the inventor has proposed the following improvement plan after research, which is explained below.

[0038] See also Figures 2 to 3 An embodiment of the utility model provides a door and window, including a door and window profile 30 and a windproof drainage hole cover 20. The door and window profile 30 is provided with a drainage hole 31, and the windproof drainage hole cover 20 is provided on the drainage hole 31.

[0039] The windproof drainage hole cover 20 is used to provide windproof drainage to the drainage hole 31 on the door and window profile 30. Figures 4 to 6As shown, it includes: an inner shell 21, the inner shell 21 is installed on the outer side of the drain hole 31, and the inner shell 21 is provided with a first through hole 211, and the first through hole 211 is connected to the drain hole 31; a windproof sheet 22, the windproof sheet 22 is connected to the outer side of the inner shell 21, and the windproof sheet 22 is attached to the periphery of the first through hole 211; wherein the windproof sheet 22 is made of soft rubber material. It can be understood that the inner shell 21 is fixed to the outer side of the drain hole 31 as a mounting base, and the windproof sheet 22 is connected to the outer side of the inner shell 21. Since the windproof sheet 22 made of soft rubber material can be closely attached to the first through hole 211, the generation of the gap 11 is effectively avoided, thereby enhancing the windproof and insect-proof function of the doors and windows, ensuring that the windproof sheet 22 can stably cover the drain hole 31, and play a role in windproof and insect-proof.

[0040] Furthermore, an inclined surface 212 is provided on the side of the inner shell 21 facing the windproof sheet 22. The inclined direction of the inclined surface 212 is gradually approaching the windproof sheet 22 from bottom to top. The windproof sheet 22 is inclined and fits on the inclined surface 212. The design of the inclined surface 212 enables the windproof sheet 22 to fit more closely on the periphery of the first through hole 211.

[0041] Furthermore, the windproof sheet 22 is snap-fitted to the inner shell 21. Specifically, the windproof sheet 22 is provided with a connecting column 221 and a blocking portion 222 connected to the connecting column 221, and the inner shell 21 is provided with a snap-fitting hole 215, the connecting column 221 is inserted into the snap-fitting hole 215, and the blocking portion 222 is held outside the snap-fitting hole 215.

[0042] In this embodiment, if Figure 8 As shown, by inserting the connecting column 221 into the clamping hole 215, the windproof sheet 22 can be quickly and conveniently installed on the inner shell 21. The size of the connecting column 221 is smaller than the size of the clamping hole 215, so that the connecting column 221 can be inserted into the clamping hole 215. The size of the blocking portion 222 is larger than the size of the clamping hole 215 in at least one direction, so that the blocking portion 222 abuts against the outside of the clamping hole 215, that is, the blocking portion 222 abuts against the side of the inner shell 21 facing the door and window profile 30, so that the windproof sheet 22 cannot be separated from the inner shell 21 from the outside, and the windproof sheet 22 itself is larger in size and can abut against the side of the inner shell 21 away from the door and window profile 30, and the two form a stable clamping structure. The blocking portion 222 can be made of a deformable material. When the windproof sheet 22 needs to be replaced or repaired, it only needs to apply external force to deform the blocking portion 222, and the connecting column 221 is pulled out of the clamping hole 215, so that the windproof sheet 22 can be easily removed. Since a stable clamping structure is formed between the windproof sheet 22 and the inner shell 21 , the windproof sheet 22 can fit more closely on the periphery of the first through hole 211 , thereby improving the sealing performance of the windproof drainage hole cover 20 .

[0043] Preferably, at least two connecting columns 221 are provided and located on the upper side of the wind shield 22, at least two corresponding snap-in holes 215 are provided and the snap-in holes 215 are located on the upper side of the first through hole 211, and the wind shield 22 is fixed to the inner shell 21 by at least two connecting columns 221, forming a multi-point fixing structure, so that the wind shield 22 has better stability.

[0044] Furthermore, the windproof drain hole cover 20 of the present solution further includes an outer shell 23, which is connected to the outer side of the inner shell 21. The outer shell 23 and the inner shell 21 enclose a protective cavity, and the windproof sheet 22 is located in the protective cavity. The protective cavity can block the intrusion of external impurities such as dust and insects, keep the windproof sheet 22 clean and intact, and also enhance the sealing performance of the windproof drain hole cover 20. Optionally, the outer shell 23 is snap-fitted with the inner shell 21 to facilitate disassembly and maintenance.

[0045] Furthermore, the top of the outer shell 23 is fitted with the door and window profile 30, and the bottom of the outer shell 23 is separated from the inner shell 21. The bottom of the protective cavity has an opening for drainage, so that the outside wind can only blow into the protective cavity from bottom to top through the opening. When the wind blows onto the wind shield 22, due to the inclined design of the wind shield 22, the wind flows in the inclined direction of the wind shield 22, and makes the wind shield 22 fit more closely with the first through hole 211.

[0046] Furthermore, a gasket 24 is provided between the inner shell 21 and the door and window profile 30 .

[0047] Specifically, the gasket 24 is a double-sided adhesive gasket.

[0048] In this embodiment, considering that the windproof drain hole cover in the prior art is connected to the door and window profile 30 in a buckle form, a buckle gap 12 is left between the windproof drain hole cover and the door and window profile 30 after installation. At the same time, the installed windproof drain hole cover is easy to fall off during transportation, resulting in functional loss, so that the connection surface between the drain hole cover and the door and window profile 30 is not tightly fitted, and there is an installation gap that is easy to let in wind, water, and mosquitoes. In order to overcome the above defects, this embodiment sets a double-sided adhesive gasket between the inner shell 21 and the door and window, so that the connection surface between the inner shell 21 and the door and window profile 30 is more tightly fitted, reducing or even eliminating the installation gap.

[0049] Furthermore, a double-sided adhesive gasket is provided along the periphery of the inner shell 21 , so that the inner shell 21 and the drainage hole 31 are tightly bonded and sealed.

[0050] Furthermore, a connection portion 213 extending into the drain hole 31 is provided on one side of the inner shell 21 facing the drain hole 31, and a snap-on spring piece 214 snap-on to the periphery of the drain hole 31 is provided on the side of the connection portion 213. The connection portion 213 enables the windproof drain hole cover 20 to be more deeply combined with the drain hole 31, thereby improving the stability of the connection, and the snap-on spring piece 214 on the side of the connection portion 213 can be elastically snap-on to the inner periphery of the drain hole 31, further enhancing the connection stability between the windproof drain hole cover 20 and the door and window profile 30, and effectively preventing the windproof drain hole cover 20 from falling off or shifting during use.

[0051] It can be understood that, whether through the adhesive connection of the double-sided adhesive gasket or the physical clamping of the connecting portion 213 and the snap-on spring 214, the windproof drainage hole cover 20 is more stable during use and is not easy to fall off or shift. In one embodiment, the inner shell 21 and the door and window profile 30 can be adhesively connected by a double-sided adhesive gasket, or physically clamped by the connecting portion 213 and the snap-on spring 214. It is also possible to achieve physical clamping with the connecting portion 213 and the snap-on spring 214 while also achieving adhesive connection through the double-sided adhesive gasket.

[0052] Furthermore, the windproof drain hole cover 20 of this embodiment includes a first state and a second state, such as Figure 7 As shown, Figure 7 2 is a cross-sectional view of the first state of the windproof drain hole cover 20. When the windproof drain hole cover 20 is in the first state, the windproof sheet 22 is tightly fitted to the periphery of the first through hole 211. In the first state, the tightly fitting design of the windproof sheet 22 ensures that the windproof drain hole cover 20 can effectively play its windproof and insect-proof functions in most cases, preventing external factors such as wind, rain and insects from entering the room through the first through hole 211 and the drain hole 31. Fig. 9 As shown, Fig. 9 The windproof drain hole cover 20 is a cross-sectional view of the second state. When the windproof drain hole cover 20 needs to enter the second state, the windproof sheet 22 will be deformed to form a drainage gap with the periphery of the first through hole 211. This design allows the windproof sheet 22 to be deformed and opened under the pressure of the accumulated water in the first through hole 211 when drainage is required, so that the accumulated water can be discharged smoothly and avoid the accumulated water from being retained inside the door and window profile 30. It should be noted that due to the characteristics of the soft rubber material of the windproof sheet 22, the windproof sheet 22 can be transformed between the first state and the second state. Specifically, the first state of the windproof sheet 22 is the initial state, and the second state is the state after the windproof sheet 22 is deformed by the pressure of the accumulated water on one side of the drain hole 31.
