Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a combined door leaf structure and a swing door system using the same. Background Technology
[0002] Aluminum honeycomb soundproof doors are currently one of the most widely used types of soundproof doors on the market. They mainly consist of a main frame profile, a panel, an aluminum honeycomb core, and end-sealing profiles. The main frame profile is fitted around the outer perimeter of the aluminum honeycomb core. The panel is attached to both ends of the aluminum honeycomb core and aluminum profile using adhesives or other methods. The end-sealing profiles are assembled around the outer perimeter of the main frame profile. Currently, the panels and aluminum profiles of existing aluminum honeycomb soundproof doors are primarily fixed together using adhesives, resulting in insufficient connection strength.
[0003] like Figure 1 As shown, this is one of the most common composite core door panel structures in existing technology. It includes a first panel A, a second panel B, an end-sealing profile C, a main frame profile D, and a core E. The assembly method is as follows: first, glue is applied to the connecting surfaces of the first panel A and the second panel B; then, the main frame profile D is attached to the first panel A; and the connection is reinforced by inserting a first screw F. Next, the core E is laid out, and then the second panel B is placed over the upper surfaces of the core E and the main frame profile D. Finally, the end-sealing profile C is connected to the main frame profile D and the second panel B using a second screw G. Compared to traditional technologies, this method uses glue and screws to achieve a fixed connection between the main frame profile and the panel, resulting in better connection strength than a simple glue-only method. However, it also has the following disadvantages: 1. The second screw G is prone to cracking the second panel B during the driving process (because the panel is too thin) or breaking through the second panel B (if it is driven crookedly), resulting in a high damage rate, high installation difficulty and high requirements; 2. The end-sealing profile C and the second panel B are mainly connected by the second screw G, and the second screw G is driven into the second panel B in a horizontal manner, which makes it easy to loosen and the connection strength is insufficient. 3. The end-sealing profile C is difficult to conceal with the end cap, resulting in poor aesthetics. Utility Model Content
[0004] The purpose of this utility model is to provide a combined door leaf structure and a swing door system using the same, which can at least solve one of the above-mentioned problems.
[0005] According to one aspect of the present invention, a combined door panel structure is provided, including a first panel, a second panel, and a core, and further including a first profile and a second profile that cooperate with each other. The first profile has a first protrusion for fixed connection with the first panel, and the second profile has a second protrusion for fixed connection with the second panel. The first profile and the second profile cooperate with each other and can be combined to form a profile main frame covering the periphery of the core.
[0006] In some embodiments, the length extension direction of the first protrusion is consistent with the length extension direction of the first panel, and the length extension direction of the second protrusion is consistent with the length extension direction of the second panel.
[0007] In some embodiments, the first protrusion includes at least a first horizontal segment whose length extension direction is consistent with the length extension direction of the first panel, and the second protrusion includes at least a second horizontal segment whose length extension direction is consistent with the length extension direction of the second panel.
[0008] In some embodiments, the first protrusion further includes a first vertical segment that extends perpendicularly to the first horizontal segment to abut against the second horizontal segment; Alternatively, the second protrusion may include at least a second vertical segment that extends perpendicularly to the second horizontal segment and abuts against the first horizontal segment.
[0009] In some embodiments, the modular door structure further includes a first fastener and a second fastener, wherein the first protrusion is fixedly connected to the first panel by the first fastener, and the second protrusion is fixedly connected to the second panel by the second fastener.
[0010] In some embodiments, the modular door structure further includes a first adhesive layer and a second adhesive layer, wherein the first protrusion is fixedly connected to the first panel through the first adhesive layer, and the second protrusion is fixedly connected to the second panel through the second adhesive layer.
[0011] In some embodiments, the modular door structure also includes an end cap that mates with the first profile.
[0012] In some embodiments, the end cap is provided with a third protrusion, and the first profile is formed with a fourth protrusion that engages with the third protrusion.
[0013] In some embodiments, the modular door structure further includes a third fastener, through which the first profile and the second profile are connected and can be combined under the action of the third fastener to form a profile main frame covering the periphery of the core body.
[0014] According to another aspect of the present invention, a swing door system is also provided, including a door leaf and a door frame that cooperate with each other, wherein the door leaf is the above-described combined door leaf structure.
[0015] The beneficial effects of this utility model are: 1. Innovative structure, strong adaptability, and convenient installation: This utility model adopts a split design in which the main frame of the profile is formed by assembling the first profile and the second profile, replacing the traditional one-piece closed profile main frame. This design can not only flexibly adapt to cores of different thicknesses and has strong versatility, but also has a simple assembly process, which significantly simplifies the production process. Most importantly, the first and second profiles are connected to the corresponding panels by fasteners perpendicular to the panel surface, which fundamentally avoids the risk of panel cracking or breaking due to horizontal screwing, greatly improving the assembly success rate and the quality of finished products.
[0016] 2. High connection strength and durability: The first profile and the first panel, as well as the second profile and the second panel, can be fixed by both adhesive and vertical screws. This composite connection method is much stronger than the single adhesive fixation, making the overall structure of the door more robust and effectively improving its impact resistance and service life.
[0017] 3. Aesthetically pleasing appearance: By setting a detachable or snap-fit end cap on the outside of the first profile, the third fastener and part of the profile structure can be cleverly concealed, making the door frame look neat and beautiful, which is more in line with the aesthetic needs of modern high-end decoration.
[0018] 4. Optimized assembly process for tighter connection: The first and second profiles are connected by a third fastener that is driven in from the outside. During the process of locking the third fastener, the two profiles are pulled closer to each other, thereby driving the first and second panels that are fixed to them to move inward synchronously and press the core in the middle. This process not only enhances the tightness of the connection between the components, but also reduces or omits the long pressurization steps required in the traditional process to a certain extent, simplifies the assembly process, reduces the production difficulty, and facilitates on-site installation.
[0019] In summary, the combined door leaf structure of this utility model and the swing door system using it have many advantages, such as structural innovation, strong adaptability, convenient installation, high connection strength, sturdiness and durability, beautiful appearance, simple assembly process, and on-site installation.

Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1 Figure 2 The diagram schematically illustrates a combined door structure according to one embodiment of the present invention.
[0024] The modular door structure includes a first panel 1, a second panel 2, a core 3, and a first profile 4 and a second profile 5 that cooperate with each other.
[0025] The first profile 4 has a first protrusion 41 for fixed connection with the first panel 1, and the second profile 5 has a second protrusion 51 for fixed connection with the second panel 2. The first profile 4 and the second profile 5 cooperate with each other and can be combined to form a profile main frame covering the outer periphery of the core 3.
[0026] Preferably, the length extension direction of the first protrusion 41 is consistent with the length extension direction of the first panel 1, and the length extension direction of the second protrusion 51 is consistent with the length extension direction of the second panel 2.
[0027] Preferably, the modular door structure also includes a first fastener 6 and a second fastener 7. The first protrusion 41 is fixedly connected to the first panel 1 by the first fastener 6, and the second protrusion 51 is fixedly connected to the second panel 2 by the second fastener 7.
[0028] Preferably, the modular door structure further includes a first adhesive layer 9 and a second adhesive layer 10. The first protrusion 41 is fixedly connected to the first panel 1 through the first adhesive layer 9, and the second protrusion 51 is fixedly connected to the second panel 2 through the second adhesive layer 10.
[0029] As a further preferred embodiment, the first profile 4 and the first panel 1 are doubly secured by a first adhesive layer 9 and a first fastener 6. Specifically, the first adhesive layer 9 is first applied to the back of the first panel 1, then the first profile 4 is attached, and finally, multiple first fasteners 6 (such as self-tapping screws) are vertically driven into the inner side of the first protrusion 41 and tightened through the first protrusion 41 to the back of the first panel 1. This vertical driving method greatly reduces the risk of damaging the thin panel. Similarly, the second profile 5 and the second panel 2 are doubly secured by a second adhesive layer 10 and a second fastener 7. Specifically, the second adhesive layer 10 is first applied to the back of the second panel 2, then the second profile 5 is attached, and finally, multiple second fasteners 7 (such as self-tapping screws) are vertically driven into the inner side of the second protrusion 51 and tightened through the second protrusion 51 to the back of the second panel 2.
[0030] For aesthetic purposes, an end cap 11 is installed on the outside of the assembled profile main frame, and the end cap 11 mates with the first profile 4. The inner side of the end cap 11 has at least one third protrusion 111, while the corresponding position on the outer side of the first profile 4 has a fourth protrusion 42 that engages with the third protrusion 111. Through the limiting engagement (hooking) between the third protrusion 111 and the fourth protrusion 42, the end cap 11 can be securely and aesthetically installed on the profile main frame, covering the installation location of the third fastener 8 and part of the profile joint.
[0031] Preferably, the modular door structure also includes a third fastener 8, and the first profile 4 and the second profile are connected by the third fastener 8 and can be combined under the action of the third fastener 8 to form a profile main frame covering the outer periphery of the core 3.
[0032] As a further preferred embodiment, the first fastener 6, the second fastener 7, and the third fastener 8 can all be screws, and there can be multiple screws.
[0033] The assembly steps of the combined door leaf structure of this utility model are as follows: S1. Assemble the first frame and the second frame: Assemble multiple first profiles 4 and multiple second profiles 5 into a square first frame and a square second frame by using corner brackets; S2. Assemble the first panel 1 and the second panel 2: Apply glue to one side of the first panel 1 to obtain a first adhesive layer 9, and make the side of the first adhesive layer 9 face upward. Place the first frame assembled in step S1 above the first panel 1 and align it. Similarly, apply glue to one side of the second panel 2 to obtain a second adhesive layer 10, and make the side of the second adhesive layer 10 face upward. Place the second frame assembled in step S1 above the second panel 2 and align it. S3. Reinforced connection (optional): After the first adhesive layer 9 and the second adhesive layer 10 have cured, multiple first fasteners 6 (such as self-tapping screws) are driven vertically into the inner side of the first frame and passed through the first protrusion 41 to be tightened to the back of the first panel 1. Multiple second fasteners 7 (such as self-tapping screws) are driven vertically into the inner side of the second frame and passed through the second protrusion 51 to be tightened to the back of the second panel 2. At this point, the first frame and the first panel 1, and the second frame and the second panel 2 are firmly connected. S4. Install core 3: Place core 3 into the space formed by the first frame and the first panel 1 or the space formed by the second frame and the second panel 2, and make one end face of core 3 adhere to the adhesive surface of the first panel 1 or the second panel 2. S5. Assembly: Invert the frame with the core 3 so that the core 3 faces upward. Then cover the core 3 with another frame without the core 3. By fine-tuning the first frame and the second frame, the two are fastened together. The third fastener 8 is driven into the frame from the outer periphery of the first frame. During the process of driving the third fastener 8, because the head of the third fastener 8 is small and the tail is large, the first frame and the second frame will move closer to each other under the pull of the third fastener 8. At the same time, the first panel 1 and the second panel 2 are pulled closer to each other. This process can simulate the pressing action of the pressing equipment, which can strengthen the connection strength. At the same time, it can save the pressing time of the subsequent pressing equipment or even eliminate the need for the pressing equipment. S6. Install end cap 11: Assemble the end cap 11 around the perimeter to obtain the finished door leaf 100.
[0034] Figure 3 A swing door system according to one embodiment of the present invention is schematically shown.
[0035] The swing door system includes a door leaf 100 and a door frame 200 that cooperate with each other, and the door leaf 100 is the above-mentioned combined door leaf structure.
[0036] The combined door leaf structure of this utility model and the swing door system using it have at least the following advantages over the prior art: 1. Innovative structure, strong adaptability, and convenient installation: This utility model adopts a split design in which the main frame of the profile is formed by assembling the first profile 4 and the second profile 5, replacing the traditional one-piece closed profile main frame. This design can not only flexibly adapt to cores 3 of different thicknesses and has strong versatility, but also has a simple assembly process, which significantly simplifies the production process. Most importantly, the first and second profiles 5 are connected to the corresponding panels by fasteners perpendicular to the panel surface, which fundamentally avoids the risk of panel cracking or breaking due to horizontal screw tapping, greatly improving the assembly success rate and product quality.
[0037] 2. High connection strength and durability: The first profile 4 and the first panel 1, and the second profile 5 and the second panel 2 can be fixed by both adhesive and vertical screw fastening. The strength of this composite connection method is much higher than that of single adhesive fixing, making the overall structure of the door leaf 100 more solid and effectively improving its impact resistance and service life.
[0038] 3. Aesthetically pleasing appearance: By setting a detachable or snap-fit end cap 11 on the outside of the first profile 4, the third fastener 8 and part of the profile structure can be cleverly concealed, making the door leaf 100 frame look neat and beautiful, which is more in line with the aesthetic needs of modern high-end decoration.
[0039] 4. Optimized assembly process for tighter connection: The first profile 4 and the second profile 5 are connected by a third fastener 8 that is driven in from the outside. During the process of locking the third fastener 8, the two profiles are pulled closer to each other, thereby driving the first panel 1 and the second panel 2 that are fixed to them to move inward synchronously and press the core 3 in the middle. This process not only enhances the tightness of the connection between the components, but also reduces or omits the long pressurization steps required in the traditional process to a certain extent, simplifies the assembly process, reduces the production difficulty, and facilitates on-site installation.
