Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a cover device for drainage holes in doors and windows. Background Technology

[0002] Currently, in door and window profiles, metal mesh is bonded to drainage holes using double-sided adhesive. However, this adhesive is prone to aging and failure in environments with large temperature differences between -40°C and +40°C. Residual adhesive is difficult to remove during disassembly and maintenance, damaging the anodized layer of the profile. The concentrated stress on the metal mesh causes edge tearing, resulting in a lifespan of less than three years.

[0003] Another type is current plastic products. Due to the large pore size of plastic products, they are not very effective at preventing mosquitoes and insects. Moreover, after being exposed to wind, rain, and sun, they are prone to aging and have a short service life. Summary of the Invention

[0049] In one embodiment of this utility model, both the metal cover plate 110 and the metal mesh 150 are made of metal.

[0050] The cover device 100 for door and window drainage holes of this utility model is made of metal material for both the metal cover plate 110 and the metal mesh 150. It has the advantages of being durable and reduces the frequency of replacing the metal mesh 150, and even the frequency of replacing the entire cover device.

[0051] Combination Figure 1 and Figure 2In one embodiment of this utility model, the snap-fit ​​structure 120 and the metal mesh 150 are located on the same side of the metal cover plate 110.

[0052] By placing the snap-fit ​​structure 120 and the metal mesh 150 on the same side of the metal cover plate 110, users can only observe part of the metal cover plate 110 and part of the metal mesh 150 from the indoor side, while the edge areas of the snap-fit ​​structure 120 and the metal mesh 150 are hidden, thus improving the overall aesthetics of the door and window structure.

[0058] Figure 3 This is a schematic diagram of one side of the cover device 100 for door and window drainage holes according to the second embodiment of this utility model. Figure 4 This is a schematic diagram of the other side of the cover device 100 for door and window drainage holes according to the second embodiment of the present invention, as shown below. Figure 3 and Figure 4As shown, in one embodiment of the present invention, the snap-fit ​​structure 120 includes a first snap-fit ​​strip 130 and a second snap-fit ​​strip 140. The first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 extend in different directions. Parts of the first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 can extend to the other side of the door and window drainage hole and snap-fit ​​at the door and window drainage hole position.

[0059] The first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 snap onto the drain hole of the door or window to fix the entire cover device. Part of the first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 extend to the other side of the drain hole of the door or window, so that the metal cover plate 110 can cover the profile of the door or window, and then the drain hole can be covered by the metal mesh 150.

[0060] The first locking strip 130 and the second locking strip 140 extend in different directions, which can fix the metal cover plate 110 in multiple directions and prevent the metal cover plate 110 from falling off the door and window drainage hole.

[0061] The first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 can be made of the same material as the metal cover plate 110, or the first snap-fit ​​strip 130 and the metal cover plate 110 can be integrated into one structure, with the first snap-fit ​​strip 130 bent at the edge of the through hole 111; or the second snap-fit ​​strip 140 and the metal cover plate 110 can be integrated into one structure, with the second snap-fit ​​strip 140 bent at the edge of the through hole 111.

[0062] Combination Figure 3 and Figure 4 The length of the first snap-fit ​​strip 130 is greater than the length of the second snap-fit ​​strip 140. A first snap-fit ​​channel 132 is formed between the first snap-fit ​​strip 130 and the metal cover plate 110. A second snap-fit ​​channel 142 is formed between the second snap-fit ​​strip 140 and the metal cover plate 110. The length of the first snap-fit ​​channel 132 is greater than the length of the second snap-fit ​​channel 142.

[0063] It should be noted that the first snap-fit ​​channel 132 and the second snap-fit ​​channel 142 should be able to accommodate part of the metal mesh 150 and the edge area of ​​the door and window drainage holes.

[0064] Figure 5 This is a schematic diagram of one side of the cover device 100 for door and window drainage holes according to the third embodiment of this utility model. Figure 6 This is a structural schematic diagram of the other side of the cover device 100 for door and window drainage holes according to the third embodiment of this utility model, as shown below. Figure 5 and Figure 6As shown, in one embodiment of the present invention, the first snap-fit ​​strip 130 is connected to the first position 131 of the metal cover plate 110, and the second snap-fit ​​strip 140 is connected to the second position 141 of the metal cover plate 110. The distance between the first position 131 and the second position 141 is less than or equal to the maximum length of the door and window drainage hole.

[0065] The distance between the first position 131 and the second position 141 is less than the maximum length of the door and window drainage hole, making it easier to extend part of the first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 to the other side of the door and window drainage hole, thereby snapping the metal cover plate 110 onto the other side of the door and window drainage hole.

[0066] In one embodiment of the present invention, a first snap-fit ​​channel 132 is provided between the first snap-fit ​​strip 130 and the metal cover plate 110, and a second snap-fit ​​channel 142 is provided between the second snap-fit ​​strip 140 and the metal cover plate 110. The length of the first snap-fit ​​channel 132 is greater than the length of the second snap-fit ​​channel 142.

[0067] The edge area of ​​the door / window drainage hole can be extended into the first snap-fit ​​channel 132, or the edge area of ​​the other side of the door / window drainage hole can be extended into the second snap-fit ​​channel 142, so that the metal cover plate 110 can be fixed in the position of the door / window drainage hole for a long time.

[0068] It is understandable that the connection position between the first snap-fit ​​strip 130 and the metal cover plate 110 is the first position 131. When metal material is used, the first position 131 should be able to be plastically deformed to adjust the relative position between the first snap-fit ​​strip 130 and the metal cover plate 110.

[0069] Accordingly, the connection position between the second snap-fit ​​strip 140 and the metal cover plate 110 is the second position 141. When a metal material is used, the second position 141 should be able to be plastically deformed to adjust the relative position between the second snap-fit ​​strip 140 and the metal cover plate 110.

[0070] In one embodiment of the present invention, a first snap-fit ​​channel is provided between the first snap-fit ​​strip 130 and the metal cover plate, and a first snap-fit ​​protrusion 133 is provided on the first snap-fit ​​strip 130, which is used to snap onto the door and window profile.

[0071] In one embodiment of the present invention, the second snap-fit ​​strip 140 is perpendicular to the surface of the metal cover plate.

[0072] In one embodiment of the present invention, a second snap-fit ​​channel is provided between the second snap-fit ​​strip 140 and the metal cover plate, and a second snap-fit ​​protrusion 143 is provided on the second snap-fit ​​strip 140, which is used to snap onto the door and window profile.

[0073] Figure 7 This is a structural schematic diagram of one side of the cover device 100 for door and window drainage holes according to the fourth embodiment of this utility model. Figure 8 This is a schematic diagram of the other side of the cover device 100 for door and window drainage holes according to the fourth embodiment of this utility model, as shown below. Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the first snap-fit ​​strip 130 and the second snap-fit ​​strip 140 extend in opposite directions.

[0074] By engaging the metal cover plate 110 in opposite directions, the connection between the metal cover plate 110 and the drain hole of the door or window can be made more secure, preventing the metal cover plate 110 from falling off the drain hole of the door or window.

[0075] The present invention provides a cover device 100 for drainage holes of doors and windows, wherein the metal cover plate 110 can be set in various shapes, such as rectangular or waist-shaped.

[0076] This utility model also provides a door and window, the profile of which is provided with a drainage hole, and the door and window also includes a cover device, which is any of the cover devices described above. The cover device is installed on the drainage hole, and part of the metal mesh 150 covers the drainage hole.

[0077] The doors and windows provided by this utility model use a metal mesh 150 to cover the drainage holes, which can reduce the entry of foreign objects or insects into the doors and windows or indoors without affecting the drainage of accumulated water.

[0078] The cover device provided by this utility model is used for drainage holes in doors and windows. Compared with the current method of using double-sided adhesive to bond metal mesh 150 to drainage holes, the adhesive is prone to aging and failure in environments with large temperature differences between -40°C and +40°C. Residual adhesive is difficult to remove during disassembly and maintenance, which damages the anodized layer of the profile. The metal mesh 150 is subjected to concentrated stress, causing the edges to tear, resulting in a service life of less than three years. In contrast, the cover device of this utility model is made of metal, which can resist the damage caused by the large temperature difference. Therefore, the cover device of this utility model is more durable.

[0079] Compared with current plastic products, which have large pores and are not very effective at preventing mosquitoes and insects, and are prone to aging and have a short service life after being exposed to wind, rain and sun, the cover device of this utility model can overcome the above problems.

[0080] Drainage holes are typically installed on door and window profiles to drain accumulated water from inside the doors and windows to the outside environment. However, if the drainage holes are too small, water cannot drain out in time, while if they are too large, debris or pests from the outside environment can enter the doors and windows and then mistakenly enter the room. Therefore, it is necessary to properly cover the drainage holes on doors and windows to ensure smooth drainage while preventing foreign objects from entering the doors, windows, or the room. The cover device of this utility model is made of metal, which can resist the damage caused by the large temperature differences mentioned above. Therefore, the cover device of this utility model is more durable.

[0081] This utility model discloses a non-adhesive, reusable metal drainage hole cover structure. It ensures drainage efficiency while reliably securing the metal mesh 150. The drainage hole cover has a long service life, is easy to install, requires no adhesive, and uses a snap-on installation. This utility model is a mosquito-proof drainage hole cover structure for thermally broken aluminum alloy system doors and windows, particularly focusing on the snap-on fixing technology for drainage hole covers with metal mesh 150 protection.

[0082] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model.
