Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window drainage technology, and in particular to a leak-proof door and window drainage structure. Background Technology
[0002] Doors and windows are an important part of the building envelope. They are usually composed of frames, sashes, glass and hardware accessories, and have functions such as lighting, ventilation, sound insulation, heat insulation and security. They play a role in separating and connecting the internal and external environments in the building space.
[0003] In the building envelope, doors and windows play a crucial role in drainage. This ensures that rainwater entering the door and window cavities is drained in a timely manner, preventing rainwater from accumulating inside and seeping into the room, thus affecting the building's waterproofing performance and the indoor environment. Leak-proof door and window drainage structures, through scientifically designed drainage channels, reasonable placement of drainage holes, and the use of sealing measures such as sealing strips, can effectively guide rainwater out, prevent rainwater backflow and leakage, and guarantee the building's waterproofing effect and living comfort.
[0004] However, existing leak-proof door and window drainage structures have the following shortcomings:
[0005] In existing technologies, leak-proof door and window drainage structures typically have drainage holes in the doors and windows to allow water to drain smoothly. However, over time, insects, dust, and debris can clog the drainage holes, causing poor drainage and leading to increased water accumulation inside the doors and windows, thus increasing the risk of leakage.
[0006] Therefore, we propose a leak-proof door and window drainage structure to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this invention is to provide a leak-proof door and window drainage structure that uses a filter component to filter rainwater entering the door and window drainage system. At the same time, the filter component can be quickly disassembled by means of the quick-fixing function of the elastic fixing component, thereby solving the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof door and window drainage structure, comprising an aluminum alloy outer frame, two slide rails fixedly installed on the inner surface of the aluminum alloy outer frame, door and window sashes movably fitted on the outer surface of the two slide rails, four sets of water inlet holes opened on the inner surface of the aluminum alloy outer frame, four sets of mounting grooves opened on the inner surface of the aluminum alloy outer frame, movable blocks movably inserted into the inner surface of the four sets of mounting grooves, pull blocks fixedly connected to the top of the four sets of movable blocks, embedding frames movably fitted between the outer surface of the four sets of pull blocks, and filter screens fixedly connected to the inner surface of the four embedding frames.
[0009] Preferably, each of the four mounting brackets has a set of fixing slots on its outer wall, and the outer walls of the four sets of movable blocks are movably inserted into the four sets of fixing slots.
[0010] Preferably, a return spring is fixedly connected to one side of the outer wall of each of the four sets of movable blocks, and the outer wall of the four sets of return springs is fixedly connected to the inner wall of the four sets of mounting slots.
[0011] Preferably, the inner surface wall of the aluminum alloy outer frame is provided with a drainage cavity.
[0012] Preferably, four sets of drainage holes are provided on one side of the outer wall of the aluminum alloy frame.
[0013] Preferably, four water guide shells are fixedly installed on one side of the outer wall of the aluminum alloy frame, and the output ends of the four sets of drainage holes are fixedly connected to one side of the outer wall of the four water guide shells.
[0014] Preferably, each of the four water guide shells has a set of water outlet holes on its inner surface wall.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, through the interaction of the various components of the device, the filter component can filter rainwater entering the door and window drainage system. At the same time, with the quick-fixing function of the elastic fixing component, the filter component can be quickly disassembled. In this way, it can be ensured that mosquitoes, dust and debris will not clog the drainage holes during the long-term use of doors and windows, maintaining the unobstructed drainage channel of doors and windows, ensuring that water inside the doors and windows is discharged in time, effectively reducing the risk of leakage. Moreover, the easy disassembly of the filter component makes it convenient for users to maintain it, and can quickly restore the filtration performance of the filter screen, so that the drainage system can continue to operate efficiently.
[0017] 2. In this utility model, through the interaction of the various components of the device, rainwater can be discharged from the water outlet at the bottom of the water guide shell. By allowing the rainwater to be discharged from the bottom of the water guide shell, the water guide shell can effectively block the external wind and prevent the wind from directly acting on the water outlet. In addition, the water outlet hidden inside the water guide shell can also prevent mosquitoes and debris from entering, thus eliminating the problem of poor drainage caused by blockage.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as shown in the attached document Figure 1 - Appendix Figure 4 As shown, this utility model provides a technical solution: a leak-proof door and window drainage structure, including an aluminum alloy outer frame 1, two slide rails 2 are fixedly installed on the inner surface of the aluminum alloy outer frame 1, and door and window sashes 3 are movably fitted on the outer surface of the two slide rails 2, four sets of water inlet holes 4 are opened on the inner surface of the aluminum alloy outer frame 1, four sets of mounting grooves 5 are opened on the inner surface of the four sets of mounting grooves 5, movable blocks 6 are movably inserted into the inner surface of the four sets of mounting grooves 5, pull blocks 7 are fixedly connected to the top of the four sets of movable blocks 6, and embedding frames 8 are movably fitted between the outer surface of the four sets of pull blocks 7, filter screens 9 are fixedly connected to the inner surface of the four sets of embedding frames 8, and a set of fixing grooves 10 are opened on the outer surface of the four sets of embedding frames 8, and the outer surface of the four sets of movable blocks 6 is movably inserted into the interior of the four sets of fixing grooves 10.
[0026] The effect achieved by the entire embodiment 1 is as follows: During use, when rainwater falls onto the inner surface of the aluminum alloy frame 1 or the outer surface of the two door and window sashes 3, the rainwater will enter the drainage chamber 12 through the four sets of water inlets 4. At this time, the four filter screens 9 at the top of the four sets of water inlets 4 will filter the rainwater to prevent insects and debris from blocking the water inlets 4 or accumulating inside the drainage chamber 12, thereby ensuring smooth drainage of the drainage chamber 12 and allowing rainwater to be discharged in time. When the four filter screens 9 have been used for a long time and have intercepted too many impurities, resulting in a significant reduction in the amount of water entering the system, the user can pull the corresponding set of pull blocks 7. The set of pull blocks 7 will drive a set of movable blocks 6 to move out of the corresponding fixed groove 10, thereby releasing the fixing of the mounting bracket 8. At this time, the mounting bracket 8 can be moved out of the aluminum alloy frame 1, making it convenient to clean the filter screens 9 inside the mounting bracket 8, thereby restoring the filtering performance of the filter screens 9 and enabling the drainage system to operate continuously and efficiently.
[0027] Example 2, as Figure 2-4 As shown, a return spring 11 is fixedly connected to one side of the outer wall of each of the four sets of movable blocks 6, and the outer wall of the four sets of return springs 11 is fixedly connected to the inner wall of the four sets of mounting grooves 5. A drainage cavity 12 is opened on the inner wall of the aluminum alloy frame 1, and four drainage holes 13 are opened on one side of the outer wall of the aluminum alloy frame 1. Four water guide shells 14 are fixedly installed on one side of the outer wall of the aluminum alloy frame 1, and the output end of the four sets of drainage holes 13 is fixedly connected to one side of the outer wall of the four water guide shells 14. A set of water outlet holes 15 is opened on the inner wall of each of the four water guide shells 14.
[0028] The effect achieved by the entire embodiment 2 is as follows: During use, due to the inclined design inside the drainage chamber 12, rainwater flows towards the four sets of drainage holes 13 under the action of gravity. Subsequently, the rainwater enters the water guide shell 14 through the four sets of drainage holes 13 and is discharged through the water outlet 15 at the bottom of the water guide shell 14. This design avoids the drawbacks of traditional direct drainage on the outer frame and effectively prevents the external wind from generating a certain reverse pressure that hinders the discharge of rainwater. The rainwater is discharged from the bottom of the water guide shell 14, which enables the water guide shell 14 to block the external wind and prevent the wind from directly acting on the water outlet 15. Moreover, the water outlet 15 is hidden inside the water guide shell 14, which can prevent mosquitoes or debris from entering the water outlet 15 and causing blockage.
[0029] The working principle of the entire device is as follows: When rainwater falls on the inner wall of the aluminum alloy frame 1 or the outer wall of the two door / window sashes 3 under the influence of wind, the rainwater flows into the drainage chamber 12 through the four sets of water inlets 4. At this time, the four filter screens 9 located at the top of the four sets of water inlets 4 will filter the rainwater to prevent insects and debris from blocking the water inlets 4 or accumulating inside the drainage chamber 12, ensuring smooth drainage. When the four filter screens 9 have blocked a large amount of impurities due to long-term use, resulting in a significant reduction in the water inflow, the user can pull the corresponding set of pull blocks 7. The set of pull blocks 7 will drive a set of movable blocks 6 to move out of the corresponding fixing slot 10, thereby releasing the fixing of the mounting bracket 8. At this time, the user can install the mounting bracket. The frame 8 can be removed from the aluminum alloy frame 1 to facilitate cleaning or replacement of the filter screen 9 inside the frame 8, thereby restoring the filtration performance of the filter screen 9. Furthermore, under the elastic support of a set of return springs 11, the frame 8 and the filter screen 9 can remain stable during use. Due to the inclined design inside the drainage chamber 12, rainwater flows towards the four sets of drainage holes 13 under the action of gravity. Subsequently, the rainwater enters the water guide shell 14 through the four sets of drainage holes 13 and is discharged through the water outlet 15 at the bottom of the water guide shell 14. In the case of strong outdoor winds, the drainage design at the bottom of the water guide shell 14 can block the external wind and prevent the wind from directly affecting the water outlet 15 and affecting the drainage effect.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
