Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a door leaf sealing component. Background Art

[0002] In the late 1980s, doors and windows were made of aluminum alloy profiles, mainly aluminum alloy windows. Although they solved some shortcomings of steel windows, the profiles themselves are made of metal materials and have fast heat and cold conduction. The K value of the whole window of steel windows and aluminum alloy windows is above 6.0w / (m2.K), which does not fundamentally solve the problems of sealing and insulation. Although they can be equipped with hollow glass, the K value of the whole window can only reach about 4.5w / (m2.K). In the mid-to-late 1990s, the thermally insulated aluminum alloy doors and windows appeared in the door and window market, which were high-end door and window products on the door and window market at that time.

[0003] The profile design utilizes high-strength insulating synthetic materials in the center, and the surface treatment utilizes advanced technologies such as powder coating, fluorocarbon coating, and resin thermal printing. These thermally insulated aluminum alloy doors and windows can meet diverse color matching needs. Their outstanding advantages include light weight, high strength, excellent water and air tightness, fire resistance, large lighting area, atmospheric corrosion resistance, long service life, excellent decorative effect, and environmental performance.

[0004] Sealing strips are needed at the opening and closing parts of doors and windows, acting between the doors and windows and the door and window frames. When the doors and windows are opened and closed, the sealing strips will be squeezed to perform a sealing function. Over time, the sides of the sealing strips squeezed by the doors and windows are prone to deformation and damage. If these damaged sealing strips are not replaced in time, the sealing strips may lose their sealing effect, and the room may experience failure in temperature regulation, increased noise penetration, and invasion of external dust and moisture.

[0005] Therefore, the present invention provides a door leaf sealing assembly to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a door leaf sealing assembly, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the door leaf sealing assembly includes a door leaf body 1, a first sealing strip 2 arranged on one side of the door leaf body 1, a second sealing strip 3 arranged on one side of the door leaf body 1, and a disassembly mechanism arranged on the door leaf body 1 for facilitating the disassembly of the first sealing strip 2 and the second sealing strip 3.

[0027] The disassembly mechanism includes a plurality of rectangular grooves 4 opened on the door leaf body 1, springs 5 arranged inside the rectangular grooves 4, plug blocks 6 slidably installed inside the rectangular grooves 4, sliders 7 fixedly installed on the plug blocks 6, plug strips 8 fixedly installed on the first sealing strip 2 and the second sealing strip 3, and slots 9 opened on the door leaf body 1 for plugging into the plug strips 8, and the plug strips 8 are provided with limiting grooves for plugging into the plug blocks 6.

[0028] One end of the spring 5 is fixedly connected to one side of the rectangular slot 4 , and the other end of the spring 5 is fixedly connected to an end of the insert 6 away from the limiting slot.

[0029] When the door leaf sealing assembly is in use, the first sealing strip 2 and the second sealing strip 3 in the door leaf sealing assembly are made of silicone rubber and have good watertightness and airtightness. The first sealing strip 2 and the second sealing strip 3, a total of six strips, are installed on the two door leaf bodies 1. During installation, the user first moves the plug 6 inside the rectangular groove 4 to both sides through the slider 7, and squeezes the spring 5 through the movement of the plug 6. Then, the plug 8 installed on one side of the first sealing strip 2 and the second sealing strip 3 is manually inserted into the interior of the slot 9. After the connection is completed, the slider 7 is released, and the elastic potential energy of the spring 5 drives the slider 7 and the plug 6 to move synchronously. In the process of moving the block 7 and the plug 6, the plug 6 will be inserted into the limit groove provided on the plug 8, fixing the two ends of the plug 6. After the sealing strip 2 and the second sealing strip 3 are deformed and damaged by the squeeze of doors and windows, when replacing the first sealing strip 2 and the second sealing strip 3, first push the two sliders 7 outward synchronously. As the sliders 7 move, they will drive the insert block 6 to move outward synchronously until the insert block 6 is completely removed from the limiting groove opened on the insert strip 8. After completing this step, the original first sealing strip 2 or the second sealing strip 3 can be easily pulled out from the slot 9. Next, the new first sealing strip 2 or the second sealing strip 3 is operated in the reverse order, and the new first sealing strip 2 and the second sealing strip 3 are inserted into the slot 9. By pushing the slider 7 in the opposite direction, the insert block 6 is re-entered and locked in the limiting groove of the insert strip 8, thereby completing the fixed installation of the new sealing strip.

[0030] Furthermore, in order to facilitate the movement of the slider 7, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a circular groove 10 is provided on the door leaf body 1 , the circular groove 10 is communicated with the rectangular groove 4 , and a rotating disk 11 is rotatably connected inside the circular groove 10 .

[0031] A rotating block 12 is fixedly connected to the top of the rotating disk 11 . A sliding groove 13 is provided on the rotating disk 11 . The sliding groove 13 is arc-shaped, and the slider 7 is slidably connected inside the sliding groove 13 .

[0032] When the door leaf sealing assembly is in use, before the inserting strip 8 is inserted into the slot 9, the rotating block 12 is rotated. This rotating action drives the rotating disk 11 to rotate synchronously. As the rotating disk 11 rotates, the slider 7 moves outward along the preset slide groove 13 trajectory. This movement synchronously drives the two sliders 7 and the connected inserting block 6 to move outward. After completing this step, the inserting strip 8 can be inserted into the slot 9. Next, in order to lock the position of the inserting strip 8, the rotating block 12 is rotated in the opposite direction. This reverse rotation drives the rotating disk 11 to rotate in the opposite direction again. As the rotating disk 11 rotates in the opposite direction, the slider 7 moves in the opposite direction along the slide groove 13, that is, moves inward until the inserting block 6 is completely embedded in the preset limit groove on the inserting strip 8, thereby achieving a stable connection between the inserting strip 8 and the slot 9. If the first sealing strip 2 or the second sealing strip 3 needs to be replaced in the future, it is only necessary to repeat the above-mentioned rotation, movement of the slider and the inserting block, and insertion and locking operation sequence to easily complete the replacement of the sealing strip. This design not only improves the assembly efficiency of the sealing assembly, but also facilitates subsequent maintenance and replacement work.

[0033] It should be noted that in order to increase the service life of the first sealing strip 2 and the second sealing strip 3, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an elliptical groove 14 is provided on the first sealing strip 2 , an elliptical member 15 is fixedly connected inside the elliptical groove 14 , and a first arched portion 16 is provided inside the second sealing strip 3 .

[0034] A first arched component 18 is fixedly connected to the interior of the first arched portion 16 . A second arched portion 17 is formed inside the second sealing strip 3 . A second arched component 19 is fixedly connected to the interior of the second arched portion 17 .

[0035] During the closing process of the door and window, the inclined surfaces of the first sealing strip 2 and the second sealing strip 3 will be squeezed by the door leaf. At this time, the elliptical part 15 located in the elliptical groove 14 will be compressed and deformed accordingly. At the same time, the first arched part 18 in the first arched part 16 and the second arched part 19 in the second arched part 17 will also be squeezed and deformed. During these deformation processes, the elliptical part 15 and the two arched parts jointly generate an outward reaction force, which effectively alleviates the deformation of the inclined surfaces of the first sealing strip 2 and the second sealing strip 3 and maintains the stability of the sealing strip. When the door and window are opened, the elliptical part 15 and the two arched parts will rebound due to their own elastic properties, causing the inclined surfaces of the first sealing strip 2 and the second sealing strip 3 to return to their initial state. This rebound mechanism not only ensures the morphological consistency of the sealing strip during the closing and opening process, but also effectively prevents the overall deformation of the sealing strip that may occur during long-term use through the supporting effect of the arched part, thereby ensuring the long-term stability of the sealing performance and extending the service life of the sealing strip.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
