Description

Technical Field

[0001] This utility model relates to the technical field of sealing accessories for hinged doors, and in particular to a quick-replacement buckle structure for the sealing strip of a hinged door frame. Background Technology

[0002] The door frame sealing strip of a hinged door is a core component that ensures the sealing performance of the door. It is widely used in various building scenarios such as homes, offices, and commercial buildings. Its main function is to fill the gap between the door frame and the door leaf, thereby achieving functions such as sound insulation, heat preservation, dust prevention, and waterproofing.

[0003] However, traditional hinged door frame sealing strips are mostly installed and fixed with a slot. In the traditional slot installation method, the strip and the slot are tightly interlocked. After long-term use, the strip is prone to aging and sticking to the slot. Disassembly requires the use of tools to pry it open, which is not only time-consuming and laborious, but also easily causes the strip to break and the slot to deform. For example, the sealing strip of a kitchen swing door in a family has aged and failed due to long-term contact with oil stains and needs to be replaced. The door uses a traditional slot-type fixing structure. Because the sealing strip is severely stuck to the slot, when the user tries to pry it open with a screwdriver, not only does the sealing strip break into multiple pieces and the remaining parts are difficult to remove, but the edges of the door frame slot also show deformation and paint peeling. Utility Model Content

[0004] This utility model discloses a quick-replacement buckle structure for the sealing strip of a hinged door frame, aiming to solve the technical problem that the sealing strip of a hinged door frame is mostly installed and fixed by a slot. In the traditional slot installation method, the strip and the slot are tightly interlocked. After long-term use, the strip is prone to aging and sticking to the slot. Disassembly requires the use of tools to pry it open, which is not only time-consuming and laborious, but also prone to strip breakage and slot deformation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The quick-release buckle structure for replacing the sealing strip of a swing door frame includes the door frame body and further includes: a quick-release mechanism: the quick-release mechanism includes multiple brackets connected to the outer wall of one side of the door frame body, four symmetrically distributed springs connected inside the brackets, two of the springs having the same locking block connected to one side of their outer wall, a rotating shaft rotatably connected to one side of the locking block, two rotating shafts connected to the inner wall of the same bracket, and a connecting plate connected to the outer wall of the two locking blocks away from the springs, the sealing strip body being connected to one side of the connecting plate; and a connecting mechanism: the connecting mechanism is located on one side of the outer wall of the brackets.

[0006] By adopting the above technical solution, the quick-release mechanism includes multiple card seats connected to the outer wall of one side of the door frame body. The card seats provide an installation base for the sealing strip body. At this time, four symmetrically distributed springs are connected inside the card seats. The springs generate a restoring force through their own elastic deformation, thereby providing power to the same card block connected to the outer wall of one side of two springs. In this way, the card block engages with the connecting plate under the action of the two springs, thereby fixing the connecting plate. A rotating shaft is rotatably connected to the outer wall of one side of the card block. The rotating shaft provides a rotation fulcrum for the card block, facilitating the separation and engagement of the card block and the card slot. At this time, the same connecting plate is connected to the outer wall of the two card blocks away from the springs. The connecting plate is used to connect the card block and the sealing strip body, thereby realizing the installation and fixing of the sealing strip body.

[0007] As a further embodiment of this utility model: the connecting mechanism includes two symmetrically distributed iron blocks connected to the outer wall of one side of the card seat, and two symmetrically distributed connecting grooves connected to the outer wall of the other side of the card seat. The inner wall of the connecting groove is connected to a second magnet. Every two iron blocks are connected to the outer wall of one side of every two adjacent second magnets. A first magnet is connected to the outer wall of one side of the card seat, and multiple first magnets are connected to the inner wall of one side of the same door frame body.

[0008] By adopting the above technical solution, the connecting mechanism includes two symmetrically distributed iron blocks connected to the outer wall of one side of the card seat. At this time, the outer wall of the other side of the card seat is connected to two symmetrically distributed connecting grooves. The connecting grooves provide an installation position for the second magnet and provide an insertion space for the iron blocks of adjacent card seats. The inner wall of the connecting groove is connected to the second magnet. The second magnet attracts the iron blocks by magnetic force. When the iron blocks can be attracted to the adjacent second magnet, the splicing and fixing between adjacent card seats can be realized, thereby realizing the continuous splicing of multiple card seats. At this time, a first magnet is connected to one side of the outer wall of the card seat. The first magnet attracts and fixes the card seat to the inner wall of the door frame body by magnetic force.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Enables quick installation and removal of the sealing strip. Two springs connected to the outer wall of one side of the block drive the block to engage and fix with the slot of the connecting plate. The semi-circular structure of the block, in conjunction with the rotating shaft, allows the block to rotate around the rotating shaft and disengage from the slot simply by pulling the connecting plate during disassembly, thus completing the replacement of the sealing strip.

[0010] 2. Reduce the maintenance cost of the card slot and avoid the waste of replacing the whole due to partial damage. By changing the long card slot to a segmented structure that can be spliced, the magnetic attraction of two symmetrical iron blocks on one side of the card slot, two symmetrical connecting grooves on the other side, and the second magnet in the groove, combined with the first magnet adsorption structure between the card slot and the door frame body, can achieve the effect of replacing only the damaged section of the card slot without replacing the whole section.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 3 The quick-release buckle structure for replacing the sealing strip of the swing door frame includes the door frame body 1 and also includes: a quick-release mechanism: the quick-release mechanism includes multiple card seats 2 connected to the outer wall of one side of the door frame body 1, four symmetrically distributed springs 5 ​​are connected inside the card seats 2, two of the springs 5 ​​are connected to the same card block 3 on one side of the outer wall, the card block 3 is rotatably connected to a rotating shaft 4 on one side of the outer wall, the two rotating shafts 4 are connected to the inner wall of the same card seat 2, the two card blocks 3 are connected to the same connecting plate 6 on the outer wall away from the springs 5, and the sealing strip body 7 is connected to the outer wall of one side of the connecting plate 6; a connecting mechanism: the connecting mechanism is located on one side of the outer wall of the card seat 2.

[0019] Specifically, the quick-release mechanism includes multiple card seats 2 connected to the outer wall of one side of the door frame body 1. The card seats 2 provide an installation base for the sealing strip body 7. At this time, four symmetrically distributed springs 5 ​​are connected inside the card seats 2. The springs 5 ​​generate a restoring force through their own elastic deformation, thereby providing power to the same card block 3 connected to the outer wall of one side of two of the springs 5. Thus, the card block 3 is engaged with the connecting plate 6 under the action of the two springs 5, thereby fixing the connecting plate 6. A rotating shaft 4 is rotatably connected to the outer wall of one side of the card block 3. The rotating shaft 4 provides a rotation fulcrum for the card block 3, facilitating the separation and engagement of the card block 3 and the card slot 8. At this time, the same connecting plate 6 is connected to the outer wall of the two card blocks 3 away from the springs 5. The connecting plate 6 is used to connect the card block 3 and the sealing strip body 7, thereby realizing the installation and fixing of the sealing strip body 7.

[0020] The connecting plate 6 has multiple equally spaced slots 8 on both outer walls. The locking block 3 fits into the inner wall of the slot 8. The outer wall of the locking block 3 near the slot 8 has a semi-circular structure. The connecting plate 6 has multiple equally spaced slots 8 on both outer walls. The locking block 3 is embedded in the slot 8 to achieve the positioning and fixation of the connecting plate 6. The semi-circular structure of the outer wall of the locking block 3 near the slot 8 can reduce the resistance when the locking block 3 is separated from the slot 8, making it easier to disassemble the connecting plate 6.

[0021] Specifically, the card holder 2 has an internal mounting cavity, and the outer wall of the connecting plate 6 near the card block 3 has a conical structure. The mounting cavity inside the card holder 2 provides mounting space for its internal components. When the connecting plate 6 is installed, its conical surface can form a guiding fit with the semi-circular outer wall of the card block 3, reducing the resistance when the card block 3 contacts the connecting plate 6, making it easier for the card block 3 to slide into the card slot 8 along the conical surface.

[0022] Reference Figure 2 and Figure 4 In a preferred embodiment, the connecting mechanism includes two symmetrically distributed iron blocks 10 connected to one side of the outer wall of the card holder 2, and two symmetrically distributed connecting grooves 11 connected to the other side of the outer wall of the card holder 2. The inner wall of the connecting grooves 11 is connected to a second magnet 12. Every two iron blocks 10 are connected to one side of the outer wall of every two adjacent second magnets 12. One side of the outer wall of the card holder 2 is connected to a first magnet 9, and multiple first magnets 9 are connected to one side of the inner wall of the same door frame body 1.

[0023] Specifically, the connecting mechanism includes two symmetrically distributed iron blocks 10 connected to the outer wall of one side of the card seat 2. At this time, the outer wall of the other side of the card seat 2 is connected to two symmetrically distributed connecting grooves 11. The connecting grooves 11 provide an installation position for the second magnet 12 and provide an insertion space for the iron blocks 10 of the adjacent card seats 2. The inner wall of the connecting groove 11 is connected to the second magnet 12. The second magnet 12 attracts the iron blocks 10 by magnetic force. When the iron blocks 10 can be attracted to the adjacent second magnet 12, the splicing and fixing between adjacent card seats 2 can be realized, thereby realizing the continuous splicing of multiple card seats 2. At this time, the outer wall of one side of the card seat 2 is connected to the first magnet 9. The first magnet 9 attracts and fixes the card seat 2 to the inner wall of the door frame body 1 by magnetic force.

[0024] Among them, multiple card holders 2 form a square-shaped structure, which is used to adapt to the shape of the door frame body 1.

[0025] Specifically, the outer wall of the door frame body 1 near the first magnet 9 is provided with multiple fixing grooves. The first magnet 9 is connected to the inner wall of the fixing groove. The fixing groove provides installation positioning for the first magnet 9. At this time, the first magnet 9 is connected to the inner wall of the fixing groove. The fixing groove restricts the position of the first magnet 9, ensuring that it accurately corresponds to the adsorption of the card holder 2.

[0026] It should be noted that the connection strength between the card holder 2 and the door frame body 1 is enhanced by installing another set of first magnets 9 on the inner wall of the fixing groove, which are magnetically attracted to the outer wall of one side of the card holder 2.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, both the door frame body 1 and the sealing strip body 7 are U-shaped structures, and the sealing strip body 7 is disposed on the inner wall of the door frame body 1.

[0028] Specifically, both the door frame body 1 and the sealing strip body 7 are U-shaped structures, and their shapes match each other, so that the sealing strip body 7 can completely cover the inner edge of the door frame body 1. At this time, the sealing strip body 7 is set on the inner wall of the door frame body 1, so that the sealing strip body 7 can be in close contact with the closed door leaf and play a sealing role.

[0029] Working principle: In use, first complete the assembly and fixation of the connecting mechanism. Multiple fixing slots are pre-set on the outer wall of the door frame body 1 near the first magnet 9. The first magnet 9 is then embedded into the inner wall of the fixing slot. The fixing slot restricts the position of the first magnet 9, ensuring its positioning with the card holder 2. Next, two symmetrically distributed iron blocks 10 are fixed on one outer wall of the card holder 2. A second magnet 12 is inserted into the connecting slot 11 on the other outer wall. The connecting slot 11 provides installation space for the second magnet 12 and also reserves space for inserting iron blocks 10 from adjacent card holders 2. Then, multiple card holders 2 are assembled, and the iron block 10 of one card holder 2 is inserted into the connecting slot of the adjacent card holder 2. The slot 11 and the second magnet 12 magnetically attract the iron block 10, thus splicing and fixing adjacent card seats 2. Finally, multiple card seats 2 are spliced ​​to form a U-shaped structure that fits the door frame body 1. Then, the first magnet 9 on one side of the outer wall of the card seat 2 is attracted to the first magnet 9 on the door frame body 1, thus completing the overall fixing of the card seat 2 to the door frame body 1. At this time, by aligning the slots 8 on both sides of the outer wall of the connecting plate 6 connected to the sealing strip body 7 with the two card blocks 3 and pressing them down, since the outer wall of the connecting plate 6 near the card block 3 is a conical structure, this conical surface will form a guiding fit with the semi-circular outer wall of the card block 3 near the slot 8, reducing the resistance when the card block 3 contacts the connecting plate 6. During the pressing process, the conical surface squeezes the locking block 3, causing the locking block 3 to rotate outward around the rotating shaft 4. At the same time, it squeezes the springs 5 ​​on both sides. The springs 5 ​​undergo elastic deformation and accumulate restoring force. When the connecting plate 6 is pressed to the preset position, the locking block 3 aligns with the slots 8 on both sides of the connecting plate 6. The restoring force of the springs 5 ​​pushes the locking block 3 to slide quickly into the slots 8 and fit against the inner wall of the slots 8, realizing the positioning and fixing of the connecting plate 6. This allows the sealing strip body 7 connected to the connecting plate 6 to be stably installed. At this time, both the door frame body 1 and the sealing strip body 7 have a U-shaped structure. The matching shape allows the sealing strip body 7 to completely cover the inner edge of the door frame body 1. Secondly, when it is necessary to... To replace the sealing strip, no tools are needed. Simply pull the connecting plate 6 away from the card holder 2. The side of the card block 3 closest to the card groove 8 has a semi-circular structure. This structure can significantly reduce the friction when the card block 3 separates from the card groove 8. Under the action of the pulling force, the inner wall of the card groove 8 exerts a force on the semi-circular surface of the card block 3, causing the card block 3 to rotate outward around the rotating shaft 4. At the same time, the spring 5 is squeezed again to compress it. As the pulling force continues, the card block 3 gradually separates from the card groove 8. At this time, the connecting plate 6 and the aged sealing strip body 7 can be directly removed. After replacing the new sealing strip body 7, repeat the pressing operation of the fixing stage to complete the quick replacement of the sealing strip.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection 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 scope of protection of this utility model.
