Description

Technical Field

[0001] This utility model relates to the field of entrance door technology, and in particular to an airtight structure for entrance doors. Background Technology

[0002] The front door is the first door connecting a residence to the outside world. It serves the core functions of security, privacy, and separation of interior and exterior spaces. Common materials include steel, stainless steel, and armored doors.

[0003] There is usually a gap between the bottom of a front door and the door frame. Some products on the market have an automatic lifting airtight structure that pops out a sealing strip when the door is closed to achieve an airtight seal. However, this type of airtight structure typically requires a groove to be cut into the bottom of the front door for installation. If problems arise, the front door needs to be disassembled for repairs, and the same applies to replacement, making maintenance difficult. Utility Model Content

[0004] This utility model discloses an airtight structure for an entrance door, aiming to solve the technical problem that general airtight structures usually require slotting at the bottom of the entrance door for installation, and if problems occur, the entrance door needs to be disassembled for repair or replacement, resulting in difficult maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An airtight structure for an entrance door includes an entrance door and further includes: a slot disposed on the inner walls of multiple sides of the entrance door; a sealing mechanism engaged in the slot; and a covering mechanism covering both sides of the sealing mechanism.

[0007] The sealing mechanism includes: a support frame fitted to the inner wall of the slot, with a side cover plate connected to the bottom end of the support frame via a hinge, the side cover plate also fitted to the inner wall of the slot, and the support frame and the side cover plate connected to the inner wall of the slot by bolts; a T-shaped bracket fixedly connected to one side of the inner wall of the slot, with a support rod movably inserted through the inner wall of the T-shaped bracket, and a second spring fixedly connected between the support rod and the T-shaped bracket, with one end of the support rod movably inserted through one side of the inner wall of the support frame; multiple wedge blocks one fixedly connected to the outer circumference of the support rod; multiple wedge blocks two respectively fitted to the outer walls of multiple wedge blocks one; and a sealing gasket fixedly connected to the bottom outer wall of multiple wedge blocks two, with a first spring fixedly connected between the top of the sealing gasket and the T-shaped bracket.

[0008] The sealing mechanism further includes: multiple through holes that penetrate the inner wall of the slot; and multiple screw tubes that are simultaneously fixedly connected to one side of the outer wall of the support frame, with the multiple screw tubes correspondingly inserted into the multiple through holes;

[0009] The sealing mechanism further includes: multiple mounting holes, which are disposed through the inner wall of one side of the side cover plate, and the positions of the multiple mounting holes correspond to the positions of the multiple through holes; and a square through groove, which is disposed through the support frame.

[0010] By incorporating a sealing mechanism, the sealing gasket is lowered by squeezing the support rod when the door is closed, sealing the bottom of the entrance door and achieving an airtight effect. The sealing mechanism can be observed by removing the cover, which facilitates subsequent maintenance. If the sealing mechanism malfunctions, the side cover can be flipped over to pass through the bottom of the entrance door. This not only limits the movement on both sides and ensures installation stability, but also allows the sealing mechanism to be removed without disassembling the entrance door, further reducing the difficulty of replacement.

[0011] In a preferred embodiment, the inner wall of the card slot is provided with a plurality of square through slots at equal intervals;

[0012] The covering mechanism includes: a first buckle plate and a second buckle plate, the first buckle plate being movably attached to one outer wall of the support frame, and the second buckle plate being movably attached to one inner wall of the slot; two L-shaped brackets being symmetrically fixed to one inner wall of the first buckle plate and movably attached to the inner wall of the support frame.

[0013] The covering mechanism also includes: multiple screw holes, which are simultaneously installed through the inner wall of one side of the two L-shaped brackets and the slot; a sealing door, which is connected to the inner wall of one side of the buckle plate by a hinge, and movably covers one side of multiple square through slots. A latch is installed on one side of the sealing door, and the latch is located at the connection between the sealing door and the buckle plate.

[0014] The covering mechanism further includes: multiple slots, which are set on the inner walls of the support frame and the slots; and multiple buckles, which are fixedly connected to the inner walls of buckle plate one and buckle plate two respectively, and the multiple buckles are respectively engaged in the multiple slots.

[0015] By incorporating a covering mechanism, two snap-on plates are inserted into the slots via buckles to cover both sides, ensuring the overall aesthetics of the door and facilitating maintenance of the sealing mechanism. The sealing door and the square through-slot allow for ventilation openings to facilitate indoor airflow, and the sealing door fits snugly against the square through-slot to enable opening and closing, thus optimizing the multifunctionality of the airtight structure.

[0016] In a preferred embodiment, the covering mechanism further includes: multiple square frames, fixedly connected to the inner wall of one side of the buckle plate two, and corresponding one-to-one with the positions of multiple square through slots one, the outer wall of the square frame being movably fitted to the inner wall of the square through slot one; and multiple square through slots three, which are disposed through the multiple square frames.

[0017] With the square frame in place, when dust gets into the square slot one during daily use and is difficult to clean, the second buckle can be removed. The dust will remain on the square frame due to the surface friction, thus directly removing the dust from the square slot one, making cleaning easier and reducing the difficulty of cleaning.

[0018] As described above, an airtight structure for an entrance door includes an entrance door and further includes: a slot, disposed on multiple inner walls of the entrance door; a sealing mechanism, engaged within the slot; and a covering mechanism, covering both sides of the sealing mechanism. The sealing mechanism includes: a support frame, fitted to the inner wall of the slot, with a side cover plate connected to the bottom end of the support frame via a hinge. The side cover plate is also fitted to the inner wall of the slot. The support frame and the side cover plate are simultaneously connected to the inner wall of the slot via bolts. A T-shaped bracket is fixedly connected to one inner wall of the slot, with a support rod movably inserted through the inner wall of the T-shaped bracket. A second spring is fixedly connected between the support rod and the T-shaped bracket, and one end of the support rod movably inserts through one inner wall of the support frame. Multiple wedge blocks are fixedly connected to the outer circumference of the support rod. Multiple wedge blocks are respectively fitted to the outer walls of the multiple wedge blocks. A sealing gasket is fixedly connected to the bottom outer wall of the multiple wedge blocks, and a first spring is fixedly connected between the top of the sealing gasket and the T-shaped bracket. The airtight structure for the entrance door provided by this utility model has the technical effect of facilitating daily maintenance and reducing the difficulty of replacement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The airtight structure for an entrance door disclosed in this utility model is mainly used in scenarios involving sealing entrance doors.

[0026] Reference Figures 1-3 An airtight structure for an entrance door includes an entrance door 1, and further includes: a slot 4 disposed on the inner walls of multiple sides of the entrance door 1; a sealing mechanism 5 engaged in the slot 4; and a covering mechanism 3 covering both sides of the sealing mechanism 5.

[0027] The sealing mechanism 5 includes: a support frame 501, which fits against the inner wall of the slot 4, and the bottom end of the support frame 501 is connected to a side cover plate 507 via a hinge. The side cover plate 507 also fits against the inner wall of the slot 4. The support frame 501 and the side cover plate 507 are simultaneously connected to the inner wall of the slot 4 by bolts; a T-shaped bracket 512, which is fixedly connected to one side of the inner wall of the slot 4, and a support rod 508 is movably inserted through the inner wall of the T-shaped bracket 512. A second spring 513 is fixedly connected between the support rod 508 and the T-shaped bracket 512, and one end of the support rod 508 is movably inserted through one side of the inner wall of the support frame 501; multiple wedge blocks 509, which are fixedly connected to the outer circumferential wall of the support rod 508; multiple wedge blocks 510, which are respectively fitted against the outer walls of the multiple wedge blocks 509; and a sealing gasket 503, which is fixedly connected to the bottom outer wall of the multiple wedge blocks 510. A spring 511 is fixedly connected between the top of the sealing mechanism 5 and the T-shaped bracket 512. When the door is closed, the sealing mechanism 5 compresses the spring 513 by squeezing the support rod 508, which moves the position of the wedge block 509 and squeezes the wedge block 510 and the sealing gasket 503 to move down, sealing the bottom of the entrance door and achieving an airtight effect. Since the sealing mechanism 5 is located on one side of the bottom of the entrance door 1 and is not completely covered on both sides, the condition of the sealing mechanism 5 can be observed by removing the cover mechanism 3, which facilitates subsequent maintenance. In addition, based on the hinge connection of the side cover plate 507, if the sealing mechanism 5 malfunctions, the side cover plate 507 can be flipped to be flush with the bottom of the support frame 501, and it can pass through the bottom of the entrance door 1. In this way, while achieving lateral limiting and ensuring installation stability, the sealing mechanism 5 can also be removed without disassembling the entrance door 1, further reducing the difficulty of replacement.

[0028] Reference Figure 2 and Figure 3In a preferred embodiment, the sealing mechanism 5 further includes: a plurality of through holes 504, which are disposed through the inner wall of the slot 4; and a plurality of screw tubes 505, which are fixedly connected to one side of the outer wall of the support frame 501, and the plurality of screw tubes 505 are inserted into the plurality of through holes 504 respectively.

[0029] Reference Figure 3 In a preferred embodiment, the sealing mechanism 5 further includes: a plurality of mounting holes 506, which are disposed through the inner wall of one side of the side cover plate 507, and the positions of the plurality of mounting holes 506 correspond to the positions of the plurality of through holes 504. A screw tube 505 is inserted into the through hole 504, and a bolt is inserted through the mounting hole 506 and engaged with the screw tube 505 to achieve clamping installation, avoiding direct connection with the inner wall of the slot 4 and ensuring the tightness of the connection after each replacement; and a square through slot 502, which is disposed through the support frame 501.

[0030] Reference Figure 1 and Figure 2 In a preferred embodiment, the inner wall of the slot 4 is provided with a plurality of square through slots 6 at equal intervals;

[0031] The covering mechanism 3 includes: a first buckle 301 and a second buckle 307. The first buckle 301 is movably attached to one side of the outer wall of the support frame 501, and the second buckle 307 is movably attached to one side of the inner wall of the slot 4. Two L-shaped brackets 302 are symmetrically fixed to one side of the inner wall of the first buckle 301 and are movably attached to the inner wall of the support frame 501.

[0032] Reference Figure 2 In a preferred embodiment, the covering mechanism 3 further includes: a plurality of screw holes 305, which are simultaneously disposed through the inner wall of one side of the two L-shaped brackets 302 and the slot 4; a sealing door 303, which is connected to the inner wall of one side of the buckle plate 301 by a hinge and movably covers one side of the plurality of square through slots 6, and a latch 304 is installed on one side of the sealing door 303, and the latch 304 is located at the connection between the sealing door 303 and the buckle plate 301.

[0033] Reference Figure 2 and Figure 4In a preferred embodiment, the covering mechanism 3 further includes: multiple slots 309 disposed on the inner walls of the support frame 501 and the slot 4; multiple buckles 306 respectively fixedly connected to the inner walls of buckle plate 1 301 and buckle plate 2 307, and the multiple buckles 306 respectively correspondingly snap into the multiple slots 309. In the covering mechanism 3, buckle plate 1 301 and buckle plate 2 307 respectively snap into the slots 309 through buckles 306 to cover both sides, ensuring the aesthetics of the overall door, and making disassembly convenient for maintenance of the sealing mechanism 5. At the same time, the L-shaped bracket 302 is fixed to the position of screw hole 1 305 by bolts to ensure that buckle plate 1 301 fits tightly against the inner wall of the slot 4 and can stably support the sealing door 303. The sealing door 303 and the square through slot 1 6 can be set up to provide ventilation for indoor ventilation, and the sealing door 303 fits against the square through slot 1 6 to establish opening and closing, optimizing the multi-functionality of the airtight structure.

[0034] Reference Figure 2 In a preferred embodiment, the covering mechanism 3 further includes: a plurality of square frames 308, fixedly connected to one side of the inner wall of the second buckle plate 307, and corresponding one-to-one with the positions of the plurality of square through slots 6, the outer wall of the square frame 308 being movably fitted to the inner wall of the square through slot 6; a plurality of square through slots 3, which are disposed through the plurality of square frames 308, the plurality of square frames 308 corresponding one-to-one and inserted into the plurality of square through slots 6. Based on the arrangement of the plurality of square through slots 3, the surface friction of the square frame 308 can be greatly increased. When dust enters the square through slot 6 during daily use and is difficult to clean, the second buckle plate 307 can be removed. The dust will remain on the square frame 308 due to the surface friction of the square frame 308, thereby directly removing the dust in the square through slot 6, making it convenient to clean and reducing the difficulty of cleaning.

[0035] Working principle: When the door is closed, the sealing mechanism 5 compresses the spring 513 by squeezing the support rod 508, which moves the wedge block 509 and squeezes the wedge block 510 and sealing gasket 503 downward, sealing the bottom of the entrance door and achieving an airtight effect. Since the sealing mechanism 5 is located on one side of the bottom of the entrance door 1 and is not completely covered on both sides, the condition of the sealing mechanism 5 can be observed by removing the cover mechanism 3, which facilitates subsequent maintenance. In addition, based on the hinge connection of the side cover plate 507, if the sealing mechanism 5 malfunctions, the side cover plate 507 can be flipped to be flush with the bottom of the support frame 501, allowing it to pass through the bottom of the entrance door 1. This achieves lateral limiting and ensures installation stability, while also allowing the sealing mechanism 5 to be removed without disassembling the entrance door 1, further reducing the difficulty of replacement.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
