Description
Technical Field
[0001] This utility model belongs to the field of door and window technology, specifically, it relates to a windproof and drainage hole cover and device for windows. Background Technology
[0002] Doors and windows are an important component of building envelope systems and are essential components of all buildings. Their primary functions are lighting and ventilation. During use, doors and windows must withstand rain. In rainy weather, water accumulates in the lower frames of doors and windows. If this rainwater cannot be drained to the outside in time, it may enter the room or damage the doors and windows. This necessitates the installation of drainage holes to remove water from the interior. Existing casement or sliding doors and windows generally have drainage holes on the exterior-facing side of the lower frame, through which water is drained to prevent water accumulation. While drainage holes achieve their function, their direct connection to the outside environment allows insects and debris to easily enter the internal structure of the doors and windows, affecting their use (such as corrosion, rattling noises when moving debris), and causing inconvenience to residents. Summary of the Invention
[0003] The purpose of this utility model is to provide a window windproof drainage hole cover and device, which aims to solve the technical problem that the drainage hole in the prior art is directly connected to the external environment, which makes it easy for mosquitoes or external debris to enter the internal structure of the door and window, thus affecting the use of the door and window.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a window windproof and drainage hole cover, comprising:
[0005] The hole cover body is used to connect with the window; the front end face of the hole cover body is provided with a receiving groove; the end face of the receiving groove is provided with a through hole; the rear end face of the hole cover body is provided with a through groove communicating with the through hole.
[0006] A windproof cover is movably connected to the main body of the hole cover. The windproof cover has two usage states. In the first usage state, the windproof cover closes the receiving groove and seals the through hole. In the second usage state, the windproof cover moves relative to the main body of the hole cover, releasing the windproof cover from closing the receiving groove and simultaneously releasing the seal on the through hole.
[0007] Preferably, the windproof cover is rotatably connected to the main body of the hole cover.
[0008] Preferably, the main body of the cover has a rotating hole; the windproof cover includes a windproof cover body and a rotating shaft disposed on the windproof cover body; the rotating shaft is adapted to the rotating hole; when the rotating shaft is inserted into the rotating hole, it applies a force to the windproof cover, and the windproof cover body rotates relative to the main body of the cover.
[0009] Preferably, the upper end of the front face of the windproof cover body is curved.
[0010] Preferably, the rotating hole comprises a groove portion disposed on the end face of the receiving groove and a through portion disposed on the rear end face of the windproof cover body, and the through portion communicates with the groove portion.
[0011] Preferably, the through groove is disposed at the lower end of the hole cover body, and the through groove communicates with the through hole.
[0012] Preferably, the hole cover body is inserted into the window via the connecting plate.
[0013] This utility model also provides a device, characterized in that it includes a window windproof and drainage hole cover as described in any of the above claims.
[0014] The beneficial effects of the window windproof drainage hole cover and device provided by this utility model are as follows: Compared with the prior art, the window windproof drainage hole cover and device of this utility model, through the cooperation of the windproof cover and the hole cover body, can effectively drain the water accumulated inside the window and keep the interior of the window dry. Specifically, when there is no water accumulated inside the window, the windproof cover is in the first use state, the windproof cover closes the receiving groove, and the windproof cover seals the through hole. When rain causes rainwater to accumulate inside the window, the rainwater will exert a force on the windproof cover, pushing the windproof cover to move, causing the windproof cover to change from the first use state to the second use state. At the same time, the windproof cover releases the seal on the receiving groove, thereby allowing the interior of the window to communicate with the external environment through the through hole, allowing rainwater to flow quickly from the interior of the window to the outside through the through hole. The interior of the window is always connected to the external environment through the through groove. When there is a small amount of water accumulated inside the window, the water will flow to the outside through the through groove. The setting of the through groove can effectively ensure that water does not accumulate inside the window. Attached Figure Description

[0030] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] Please refer to the following: Figures 1 to 14 The present invention provides a window windproof and drainage hole cover. The window windproof and drainage hole cover includes: a hole cover body 1 and a windproof cover 2. The hole cover body 1 is used to connect to the window frame; the front end face of the hole cover body 1 is provided with a receiving groove 11; the end face of the receiving groove 11 is provided with a through hole 12; the rear end face of the hole cover body 1 is provided with a through groove 13 communicating with the through hole 12; the windproof cover 2 is movably connected to the hole cover body 1, and the windproof cover 2 has two usage states. In the first usage state, the windproof cover 2 covers the receiving groove 11 and seals the through hole 12; in the second usage state, the windproof cover 2 moves relative to the hole cover body 1, releasing the covering of the receiving groove 11 and simultaneously releasing the seal of the through hole 12.
[0032] This utility model provides a window windproof drainage hole cover. Compared with the prior art, the windproof cover 2, through its cooperation with the hole cover body 1, can effectively drain water accumulated inside the window and maintain the dryness of the window interior. Specifically, when there is no water accumulated inside the window, the windproof cover 2 is in the first use state, covering the receiving groove 11 and sealing the through hole 12. When rain causes rainwater to accumulate inside the window, the rainwater exerts a force on the windproof cover 2, pushing it to move and change the windproof cover 2 from the first use state to the second use state. At the same time, the windproof cover 2 releases the seal on the receiving groove 11 and the through hole 12, thus allowing the interior of the window to communicate with the external environment through the through hole 12, allowing rainwater to flow quickly from the interior of the window to the outside through the through hole 12. The interior of the window is always connected to the external environment through the through groove 13. When there is a small amount of water accumulated inside the window, the water will flow into the outside through the through groove 13. The through-slot 13 effectively prevents water accumulation inside the window. The drain hole cover effectively solves the problem in existing technologies where insects or external debris can easily enter the internal structure of the door and window through the drain hole.
[0033] As one specific implementation of this utility model, please refer to the following: Figures 1 to 14 The windproof cover 2 is rotatably connected to the main body 1 of the hole cover. In the first state of use, the shape of the windproof cover 2 is adapted to the shape of the receiving groove 11. In the first state of use, the rear end face of the windproof cover 2 is in contact with the end face of the receiving groove 11, and the windproof cover 2 covers and seals the through hole 12. In the second state of use, the windproof cover 2 rotates relative to the main body 1 of the hole cover under force, and a gap is formed between the rear end face of the windproof cover 2 and the end face of the receiving groove 11, and the through hole 12 communicates with the external environment.
[0034] In some feasible embodiments, the cover body 1 is provided with a rotating hole 14. The windproof cover 2 includes a windproof cover body 21 and a rotating shaft 22 disposed on the upper end of the windproof cover body 21. The rotating shaft 22 is provided in two sets, respectively disposed on the left and right sides of the windproof cover body 21. The rotating shaft 22 is adapted to the rotating hole 14. When the rotating shaft 22 is inserted into the rotating hole 14, a force is released on the windproof cover 2, and the windproof cover body 21 will rotate relative to the cover body 1 about the rotating shaft 22 as the rotation center.
[0035] In any feasible embodiment, the upper end of the front face of the windproof cover body 21 is curved. This ensures that the windproof cover body 21 can rotate normally relative to the hole cover body 1 when subjected to force. A rotating shaft 22 is disposed on the rear face of the windproof cover body 21. Specifically, two sets of rotating shafts 22 are respectively disposed on the left and right sides of the upper end of the rear face of the windproof cover body 21. Through the curvature and the coordinated arrangement of the rotating shafts 22 on the rear face of the windproof cover body 21, it is ensured that when the windproof cover body 21 is subjected to force from the rear face, it can rotate relative to the windproof cover body 21 about the rotating shaft 22 as an axis.
[0036] In any feasible embodiment, the rotating hole 14 comprises a groove portion disposed on the end face of the receiving groove 11 and a through portion disposed on the rear end face of the windproof cover body 21, and the through portion is connected to the groove portion.
[0037] In any feasible embodiment, the rotating hole 14 is angled. Specifically, please refer to... Figure 11 The opening of the rotating hole on the rear end face of the hole cover body 1 is higher than the opening of the rotating hole on the front end face of the hole cover body 1.
[0038] As one specific implementation of this utility model, please refer to the following: Figures 1 to 14 The through groove 13 is located at the lower end of the rear end face of the hole cover body 1, and the upper end of the through groove 13 is connected to the through hole 12, while the lower end of the through groove 13 penetrates the rear end face of the hole cover body 1. The through groove 13 ensures that when the windproof and drainage hole cover for the window is installed on the window, the interior of the window can always be connected to the external environment through the through groove 13.
[0039] As one specific implementation of this utility model, please refer to the following: Figures 1 to 14 There are two types of through holes 12: through side holes and main through holes. In any feasible embodiment, there are two sets of through side holes, respectively located at the left and right ends of the receiving groove 11. There are three sets of main through holes. The three sets of main through holes are located between the two sets of through side holes, and adjacent holes are equally spaced. That is, the through holes 12 are arranged from left to right along the length of the receiving groove 11 as follows: first through side hole, first main through hole, second main through hole, third main through hole, and second through side hole.
[0040] In any feasible embodiment, the number of through slots 13 is the same as the number of main through holes. Furthermore, the number of through slots 13 corresponds one-to-one with the number of main through holes. That is, the through slots 13 are connected to the main through holes in the through holes 12.
[0041] As one specific implementation of this utility model, please refer to the following: Figures 1 to 14 The main body 1 of the hole cover is connected to the window via connecting plates 3. Specifically, there are two sets of connecting plates 3, each located on the rear end face of the main body 1. Specifically, the connecting plates 3 are positioned between the through side hole and the main through hole. That is, one set of connecting plates 3 is positioned between the first through side hole and the first main through hole. The other set of connecting plates 3 is positioned between the third main through hole and the second through side hole.
[0042] Working principle: In the first usage scenario, when the windproof cover 2 is in its first usage state, it covers the receiving groove 11 and seals the through hole 12. In the second usage scenario, when rainwater accumulates inside the window, the rainwater exerts a force on the windproof cover 2, causing it to change from the first usage state to the second usage state and remain in the second usage state, thus allowing the rainwater to flow out through the through hole 12. Once the rainwater has drained, the windproof cover 2 is no longer under pressure, and under gravity, it will change from the second usage state back to the first usage state.
