Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to an assembled door structure. Background Technology

[0002] Aluminum honeycomb soundproof doors are currently the most widely used type of soundproof door on the market. They mainly consist of an aluminum profile main frame, a panel, an aluminum honeycomb core, and end sealing profiles. The aluminum profile main frame is fitted around the outer periphery of the aluminum honeycomb core. The panel is attached to both ends of the aluminum honeycomb core and the aluminum profile by means of adhesive or other methods. The end sealing profiles are assembled around the outer periphery of the aluminum profile main frame.

[0003] As shown in the existing patent document with announcement number CN220226617U, a hidden door is disclosed, including a door frame assembly for use with a door opening in a wall and a door core assembly that matches the door frame assembly. The door core assembly includes an inner door panel, an outer door panel, and a sound insulation filler disposed between the inner door panel and the outer door panel. The door core assembly also includes a door core profile disposed outside the sound insulation filler and located between the inner door panel and the outer door panel.

[0004] As shown in the aforementioned prior art documents, the door core assembly in the prior art has the following disadvantages: 1. Aluminum profiles have fixed dimensions, and one type of aluminum profile can only be used for panels of one thickness, resulting in poor adaptability; 2. One type of end-sealing profile can only be used with one type of aluminum profile. If different thicknesses of panels are to be assembled to form different door core components, multiple specifications of aluminum profiles and end-sealing profiles are required, resulting in high inventory pressure and high production costs for manufacturing plants.

[0005] The purpose of this invention is to provide an assembled door structure that can at least solve one of the above-mentioned problems.

[0006] According to one aspect of the present invention, an assembled door structure is provided, including a frame, a core, a first panel, a second panel, and an end cap. The frame is fitted around the outer periphery of the core. The first panel and the second panel are respectively disposed on the two end faces of the frame.

[0015] In some embodiments, the frame further includes a first limiting member, a first protrusion having a first connecting hole that mates with the first limiting member, and a second protrusion having a second connecting hole that mates with the first limiting member.

[0020] The beneficial effects of this utility model are: 1. This utility model provides a novel assembled door structure.

A brand-new frame structure has been set up, which consists of two parts: a first frame and a second frame. The profiles that make up the first frame and the second frame are specially designed to allow one profile to be adapted to panels of various thicknesses, which is highly applicable and greatly reduces the inventory pressure, production costs, and transportation costs of profile manufacturing plants. 3. The stepless limiting structure is achieved in the following way: Since the first frame and the second frame can move relative to each other, this utility model adds a second limiting member. After the positions of the first frame and the second frame are determined, the second limiting member is installed first, and then the end cap is installed. In this way, no matter how the positions of the first frame and the second frame change, and no matter how much they change, the end sealing can always be completed by using only one type of end cap. 4. The stepped limit structure is achieved in the following way: Since the outer periphery of the first frame is provided with a first limit strip with multiple positions and the outer periphery of the second frame is provided with a second limit strip with multiple positions, an end cap is used to limit and cooperate with one of the first limit strips and one of the second limit strips respectively to achieve the end sealing effect. An end cap of one specification can be used to adapt to the end sealing of products of various specifications. 5. In summary, the aluminum profile of this utility model only includes three types: the first profile, the second profile, and the end cap. However, these three profiles can be used to assemble panels of various thicknesses or even any thickness, making it highly adaptable and greatly reducing the inventory pressure on manufacturing plants.

[0040] Preferably, the frame 1 in this embodiment also includes a first limiting member 13.

[0041] The first profile 111 and the second profile 121 are connected by the first limiting member 13.

[0046] Preferably, the head of the first limiting member 13 is cone-shaped.

[0047] As a further preferred embodiment, the first limiting member 13 is a pin.

[0048] The assembly process of the modular door structure of this utility model is as follows: S1. Assemble the first frame 11 and the second frame 12: Assemble the first profile 111 and the second profile 112 into a square first frame 11 and second frame 12 by using the first corner bracket and the second corner bracket respectively; S2. Assemble the first panel 3 and the second panel 4: Apply glue to one side of the first panel 3 to obtain the first adhesive layer 6, and make the first adhesive layer 6 face upward. Place the first frame 11 assembled in step S1 above the first panel 3 and align it. Similarly, apply glue to one side of the second panel 4 to obtain the second adhesive layer 7, and make the second adhesive layer 7 face upward. Place the second frame 12 assembled in step S1 above the second panel 4 and align it. S3. Install the core 2: In step S2, the core 2 can be directly placed into the space formed by the first frame 11 and the first panel 3 or the space formed by the second frame 12 and the second panel 4, so that the bottom of the core 2 is attached to the first adhesive layer 6 of the first panel 3 or the second adhesive layer 7 of the second panel 4. S4. Strengthen the connection: make the first fastener 8 pass through the first profile 111 and the second profile 112 and connect with the first panel 3, so that the first frame 11 and the first panel 3 are connected as one unit. Similarly, make the second fastener 9 pass through the second profile 121 and the fourth profile 122 and connect with the second panel 4, so that the second frame 12 and the second panel 4 are connected as one unit. Preferably, this step is performed after the first adhesive layer 6 and the second adhesive layer 7 have fully cured to prevent displacement of the first frame 11, the second frame 12 or the core 2 during the process of inserting the first fastener 8 and the second fastener 9. S5. Inserting the first limiting member 13: Invert the frame with the core 2 so that the core 2 faces upward, and then cover the core 2 with another frame without the core 2. By fine-tuning the first frame 11 and the second frame 12, the two are fastened together. After confirming that the connecting holes of the first frame 11 and the second frame 12 are aligned, multiple first limiting members 13 can be inserted sequentially from the outer periphery of the first frame 11. During the insertion of the first limiting member 13, because the head of the first limiting member 13 is small and the tail is large, the first frame 11 and the second frame 12 will move closer to each other under the pull of the first limiting member 13. At the same time, the first panel 3 and the second panel 4 are pulled closer to each other. During this process, the first limiting member 13 can play the role of strengthening the connection strength. S6. Install the second limiting member 14: The second limiting member 14 is fixedly installed on the outermost first protrusion 1111 of the first profile 111 by the third fixing member 15. S7. Install end caps: Through the limiting cooperation of the first limiting protrusion 511 and the fifth limiting protrusion 1411, the end cap 5 is fastened to the second limiting member 14. All end caps 5 are assembled around the frame 1, and the door core assembly is obtained after assembly.

[0049] This process has at least the following advantages: 1. The first frame 11 and the second frame 12 are detachably connected and are connected by the first limiting member 13. Under the action of external force, the first limiting member 13 enters from the outside of the first frame 11 and passes through the first frame 11 and the second frame 12 in sequence. The first frame 11 and the second frame 12 move closer to each other under the action of the first limiting member 13 to complete the fastening and locking. At the same time, during the movement of the first frame 11 and the second frame 12, the first panel 3 and the second panel 4 at both ends will move closer to each other and squeeze the core 2 in the middle to achieve the function of enhancing the connection strength. 2. No large mechanical equipment such as hydraulic equipment is needed during the entire assembly process, which greatly reduces costs and assembly difficulty; 2. The most difficult operation is applying glue and inserting the limiting parts, but users can basically do this themselves. 3. The entire process is time-efficient and has a short construction period; 4. Assembly can be completed at the user's end, eliminating the need for panel transportation.

[0050] Example 2 Figure 7 The diagram schematically illustrates an assembled door structure according to another embodiment of the present invention.

[0051] The structure of the assembled door structure in this embodiment is basically the same as that of the assembled door structure in Embodiment 1, except that: (1) the structure of the end cap is different; (2) the structure of the second profile 121 is different.

[0052] like Figure 7 As shown, the end cap 5 in this embodiment is right-angled, and the structure of the corresponding second profile 121 is slightly different from that in embodiment 1. Compared with the planar end cap in embodiment 1, the assembled door structure in this embodiment can form a right-angle limiting structure with the door frame.

[0053] Example 3 Figure 8 The diagram schematically illustrates an assembled door structure according to another embodiment of the present invention.

[0054] The structure of the assembled door structure in this embodiment is basically the same as that of the assembled door structure in Embodiment 1, except that: (1) the structure of the end cap is different; (2) the structure of the second limiting member is different.

[0055] like Figure 8 As shown, in this embodiment, the two ends of the end cap 5 are flush with the upper end face of the first profile 111 and the lower end face of the second profile 121, respectively. Therefore, the first panel 3 and the second panel 4 can completely cover the end cap, allowing the assembled door structure of this embodiment to function as a hidden door.

[0056] Furthermore, the end cap 5 and the second limiting member 14 in this embodiment have different structures from those in embodiment 1. Specifically, the third limiting strip 141 on the second limiting member 14 is reversed compared to embodiment 1, and the corresponding first limiting protrusion 51 on the end cap 5 is also reversed compared to embodiment 1.

[0057] Example 4 Figure 9 and Figure 10 The diagram schematically illustrates an assembled door structure according to one embodiment of the present invention.

[0058] The assembled door structure in this embodiment is basically the same as that in embodiment 1, except that the end cap and the frame 1 in this embodiment are matched by a stepped limiting structure Y.

[0059] like Figure 9-10 As shown, the stepped limit structure Y includes: A plurality of first limiting strips 112 are disposed on the outer periphery of the first profile 111 and distributed at intervals along the thickness direction of the first profile 111; a plurality of second limiting strips 122 are disposed on the outer periphery of the second profile 121 and distributed at intervals along the thickness direction of the second profile 121; a first limiting protrusion 51 is disposed on the end cap 5 and cooperates with one of the first limiting strips 112; and a second limiting protrusion 52 is disposed on the end cap 5 and cooperates with one of the second limiting strips 122.

[0060] Preferably, the first limiting strip 112 disposed on the first profile 111 is disposed on the outermost first protrusion 1111 of a pair of first protrusions 1111, and the second limiting strip 122 disposed on the second profile 121 is disposed on the outermost second protrusion 1211 of a pair of second protrusions 1211. Since the outer periphery of the first frame 11 is provided with a first limiting strip 112 with multiple positions, and the outer periphery of the second frame 12 is provided with a second limiting strip 122 with multiple positions, an end cap 5 is used to limit and cooperate with one of the first limiting strips 112 and one of the second limiting strips 122 respectively to achieve an end sealing effect.

[0061] like Figure 10 As shown, in this embodiment, the first limiting protrusion 51 is provided with a first limiting protrusion 511, the second limiting protrusion 52 is provided with a second limiting protrusion 521, the first limiting strip 112 is provided with a third limiting protrusion 1121 that cooperates with the first limiting protrusion 511, and the second limiting strip 122 is provided with a fourth limiting protrusion 1221 that cooperates with the second limiting protrusion 521.

[0062] The assembly process of the modular door structure of this utility model is as follows: S1. Assemble the first frame 11 and the second frame 12: Assemble the first profile 111 and the second profile 112 into a square first frame 11 and second frame 12 by using the first corner bracket and the second corner bracket respectively; S2. Assemble the first panel 3 and the second panel 4: Apply glue to one side of the first panel 3 to obtain the first adhesive layer 6, and make the first adhesive layer 6 face upward. Place the first frame 11 assembled in step S1 above the first panel 3 and align it. Similarly, apply glue to one side of the second panel 4 to obtain the second adhesive layer 7, and make the second adhesive layer 7 face upward. Place the second frame 12 assembled in step S1 above the second panel 4 and align it. S3. Install the core 2: In step S2, the core 2 can be directly placed into the space formed by the first frame 11 and the first panel 3 or the space formed by the second frame 12 and the second panel 4, so that the bottom of the core 2 is attached to the first adhesive layer 6 of the first panel 3 or the second adhesive layer 7 of the second panel 4. S4. Reinforced connection of fasteners: The first fastener 8 passes through the first profile 111 and the second profile 112 and is connected to the first panel 3, so that the first frame 11 and the first panel 3 are connected as one unit. Similarly, the second fastener 9 passes through the second profile 121 and the fourth profile 122 and is connected to the second panel 4, so that the second frame 12 and the second panel 4 are connected as one unit. Preferably, this step is performed after the first adhesive layer 6 and the second adhesive layer 7 have fully cured to prevent displacement of the first frame 11, the second frame 12 or the core 2 during the process of inserting the first fastener 8 and the second fastener 9. S5. Inserting the first limiting member 13: Invert the frame with the core 2 so that the core 2 faces upward. Then, cover the core 2 with another frame without the core 2. By fine-tuning the first frame 11 and the second frame 12, make them fasten together. After confirming that the connecting holes of the first frame 11 and the second frame 12 are aligned, the first limiting member 13 can be inserted from the outer periphery of the first frame 11. During the insertion of the first limiting member 13, because the head of the first limiting member 13 is small and the tail is large, the first frame 11 and the second frame 12 will move closer to each other under the pull of the first limiting member 13. At the same time, the first panel 3 and the second panel 4 will move closer to each other. During this process, the first limiting member 13 can strengthen the connection strength. S6. Install end cap: Through the limiting cooperation of the first limiting protrusion 511 and the third limiting protrusion 1121, and the limiting cooperation of the second limiting protrusion 521 and the fourth limiting protrusion 1221, the end cap 5 can be fastened to the four sides of the frame 1, and the door core assembly is obtained after assembly.

[0063] Example 5 Figure 11 The diagram schematically illustrates an assembled door structure according to one embodiment of the present invention.

[0064] The assembled door structure in this embodiment is basically the same as that in embodiment 4, except that: (1) the thickness of the first panel 3 and the second panel 4 are different; (2) the end cap 5 is positioned differently from the first limiting strip 112 and the second limiting strip 122.

[0065] In this embodiment, the spacing between the first frame 11 and the second frame 12 is adjusted to accommodate a thinner panel, and then the end cap 5 is used for end sealing to complete the assembly.

[0066] The advantages of the assembled door structure of this utility model compared with the prior art are as follows: 1. This utility model provides a novel assembled door structure. The door structure is equipped with a novel end cap and frame 1, which are matched by a stepless limiting structure W or a stepped limiting structure Y. The advantage of this is that a single end cap 5 can be used to adapt to various deformed frame 1 structures, which is low in cost and easy to assemble. 2. A completely new frame structure 1 is set up. The frame 1 includes two parts: a first frame 11 and a second frame 12. The profiles that make up the first frame 11 and the second frame 12 are specially designed to allow one profile to be adapted to panels of various thicknesses. This makes it highly adaptable and greatly reduces the inventory pressure, production costs, and transportation costs of the profile manufacturing plant. 3. The stepless limiting structure W is achieved in the following way: Since the first frame 11 and the second frame 12 can move relative to each other, this utility model adds a second limiting member 14. After the positions of the first frame 11 and the second frame 12 are determined, the second limiting member 14 is installed first, and then the end cover 5 is installed. In this way, no matter how the positions of the first frame 11 and the second frame 12 change, and no matter how much they change, the end sealing can always be completed by using only one type of end cover 5. 4. The stepped limiting structure Y is achieved in the following way: Since the outer periphery of the first frame 11 is provided with a first limiting strip 112 with multiple positions, and the outer periphery of the second frame 12 is provided with a second limiting strip 122 with multiple positions, the end cap 5 is respectively limited and cooperates with one of the first limiting strips 112 and one of the second limiting strips 122 to achieve the end sealing effect. The end cap 5 of one specification can be used to adapt to the end sealing of products of various specifications. 5. The aluminum profiles of this utility model only include three types: the first profile 111, the second profile 121, and the end cap 5. However, these three profiles can be used to assemble panels of various thicknesses or even any thickness, which is highly applicable and greatly reduces the inventory pressure of manufacturing plants. 6. The frame 1 includes two parts: a first frame 11 and a second frame 12. The first frame 11 and the second frame 12 are detachably connected and are connected by a first limiting member 13. Under the action of external force, the first limiting member 13 enters from the outside of the first frame 11 and passes through the first frame 11 and the second frame 12 in sequence. The first frame 11 and the second frame 12 move closer to each other under the action of the first limiting member 13 to complete the fastening and locking. At the same time, during the movement of the first frame 11 and the second frame 12, the first panel 3 and the second panel 4 at both ends will move closer to each other and squeeze the core 2 in the middle to achieve the function of enhancing the connection strength. This utility model not only eliminates the need for hydraulic presses and other pressure equipment for pressing, resulting in low manufacturing costs, but also eliminates the long-term and mechanized pressing work, greatly shortening the construction period. 7. The assembly process of the entire door structure is simple and quick. These parts can be shipped directly to the user, who can assemble it themselves without the need for panel transportation, thus avoiding the risk of damage during panel transportation. 8. Profile manufacturing plants do not need to perform long-term pressing work, resulting in extremely high production efficiency. At the same time, without the need for pressing equipment, the cost saved on pressing equipment can be used to improve after-sales service, such as adding on-site installation services. Compared with the existing methods, this approach is not only lower in cost, but also significantly shortens the assembly period, effectively improving the user experience and product quality.

[0067] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
