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] A hidden door is a design that blends seamlessly with the wall in terms of visual appearance, creating a more complete and unified wall surface. It is suitable for various design styles. When a hidden door is closed, the shape, size, and style of the exit are not easily discernible.

[0003] In the present technology, hidden doors typically include a door frame fixed to the door opening in the wall and a door body hinged to the door frame. The door body is usually composed of a core panel and decorative panels set on both sides of the core panel. Hidden doors are usually thin and their sound insulation performance usually cannot meet the needs of home use.

[0004] 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.

[0005] As shown in the aforementioned prior art documents, the manufacturing process of the door core assembly in the prior art is roughly as follows: S1. Assemble the door core profiles by using corner brackets to assemble the horizontal and vertical profiles into a square frame structure. S2. Apply glue to one side of one of the door panels (e.g., the inner door panel) with the glued side facing up, and place the square frame structure assembled in step S1 above the door panel, aligning it. S3. Place aluminum honeycomb or other fillers into the space formed by the square frame structure and the door panel, and make sure the bottom of the aluminum honeycomb or other fillers is in contact with the adhesive surface of the door panel. S4. Apply glue to one side of another door panel (e.g., the outer door panel) with the glued side facing down, and then place it on top of the frame structure and fillers such as aluminum honeycomb to complete the assembly and obtain the door core assembly. S5. Place one or more assembled door core components into a press for pressing. The pressing time is generally more than 10 hours.

[0006] Therefore, the prior art has at least the following drawbacks: 1. Hydraulic presses and other pressing equipment are required to complete the manufacturing process; 2. The pressing time is long and the production efficiency is low. If mass production is to be achieved, the number of equipment can only be increased, which is too costly. 3. To achieve a unified style in decoration, existing technologies require that the color of the door panels (inner and outer door panels) of the door core components match the color of the interior walls or wall panels. To achieve this, the existing technology involves the following steps: First, the user sends the door panels to the door core component manufacturer. Then, the manufacturer processes the door core components according to the aforementioned manufacturing process. Finally, the manufacturer returns the door core components to the user. This process is not only time-consuming and lengthy, but also prone to damage to the door panels during transportation. If damaged, the door panels need to be resent and the door core components need to be remanufactured, resulting in a high risk of damage and making it impossible to guarantee product quality and completion time.

The door structure features a new frame structure, which includes a first frame and a second frame. The first and second frames are detachable and locked together by a limiting member. Under external force, the limiting member enters from the outside of the first frame and passes through the first and second frames in sequence. The first and second frames move closer together under the action of the limiting member, thus completing the fastening and locking. At the same time, during the movement of the first and second frames, the first and second panels at both ends move closer together and press the core in the middle, thereby enhancing the connection strength. This structure of the 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 and mechanized pressing work, greatly shortening the construction period. 2. 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 transporting the panel, thus avoiding the risk of damage during panel transportation.

[0019] 3. The profiles that make up the first and second frames 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.

[0020] 4. 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.

[0037] This embodiment uses the example of one first limiting bar 1113a, one second limiting bar, one third limiting bar 1213a, and one fourth limiting bar.

[0038] Preferably, the head of the limiting member 13 is cone-shaped.

[0039] As a further preferred embodiment, the limiting member 13 is a pin.

[0040] As a preferred embodiment, the assembled door structure further includes an adhesive layer 6, which is disposed on one end face of the first panel 3 and the second panel 4 near the frame 1.

[0041] As a further preferred option, the adhesive layer 6 is formed by coating with environmentally friendly adhesive or the like.

[0042] Preferably, the first frame 11 is connected to the first panel 3 by a fastener 7, and the second frame 12 is connected to the second panel 4 by a fastener 7.

[0043] As a further preferred option, the fastener 7 can be a screw or other fastener.

[0044] 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 using corner brackets; S2. Assemble the first panel 3 and the second panel 4: Apply glue to one side of the first panel 3 to obtain an adhesive layer 6, and make the 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 an adhesive layer 6, and make the adhesive layer 6 face upward. Place the second frame 12 assembled in step S1 above the second panel 4 and align it. S3. Install core 2: In step S2, 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 core 2 is in contact with the adhesive surface of the first panel 3 or the second panel 4. S4. Fastener 7 reinforces the connection: the fastener 7 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 fastener 7 passes through the third 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 should be performed after the adhesive layer 6 has fully cured to prevent displacement of the first frame 11, the second frame 12, or the core 2 during the insertion of the fastener 7. S5. Inserting the 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, the two are fastened together. After confirming that the connecting holes of the first frame 11 and the second frame 12 are aligned, the limiting member 13 can be inserted from the outer periphery of the first frame 11. During the insertion of the limiting member 13, because the head of the 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 limiting member 13. At the same time, the first panel 3 and the second panel 4 are pulled closer to each other. This process can simulate the pressing action of the pressing device and achieve the effect of strengthening the connection strength. S6. Install end cap 5: Assemble end cap 5 around the perimeter to obtain the door core assembly.

[0045] This process has at least the following advantages: 1. 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 part 13, 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.

[0046] Example 2 Figure 5-8 The diagram schematically illustrates an assembled door structure according to another embodiment of the present invention.

[0047] The assembled door structure is basically the same as that of Embodiment 1, except that the structure and shape of the first profile 111, the second profile 112, the third profile 121 and the fourth profile 122 are different from those of Embodiment 1.

[0048] like Figure 5-6As shown, the outermost first protrusion 1111 includes a first inclined segment 1111b, and the first limiting portion 1113 includes a plurality of stepped and spaced first limiting strips 1113a disposed on the first inclined segment 1111b; the outermost second protrusion 1121 includes a second inclined segment, and the second limiting portion includes a plurality of stepped and spaced second limiting strips disposed on the second inclined segment; the outermost third protrusion 1211 includes a third inclined segment 1211b, and the third limiting portion 1213 includes a plurality of stepped and spaced third limiting strips 1213a disposed on the third inclined segment 1211b; the outermost fourth protrusion 1221 includes a fourth inclined segment, and the fourth limiting portion includes a plurality of stepped and spaced fourth limiting strips disposed on the fourth inclined segment.

[0049] Since the structure and shape of the second profile 112, the third profile 121 and the fourth profile 122 are the same as those of the first profile 111, this embodiment will only describe the structure of the first profile 111.

[0050] like Figure 6 As shown, the first profile 111 in this embodiment further includes a first folded edge 1114, a first broken portion 1115, and a second broken portion 1116. The first folded edge 1114 is disposed at one end of the first profile 111 and extends vertically upward based on the base surface of the first profile 111. The first broken portion 1115 is disposed at the root of the first folded edge 1114, and the second broken portion 1116 is disposed at one end of the first profile 111 near the first folded edge 1114. The first broken portion 1115 and the second broken portion 1116 can be narrow segments formed by stretching and thinning during the molding process of the first profile 111, and can be broken under external force. In use, the first folded edge 1114 can limit the first panel 3.

[0051] like Figure 7 As shown, when the first folded portion 1115 is broken off, the entire first folded edge 1114 disappears. At this time, the first panel 3 can be directly aligned with the first end cap 51, completely covering the first end cap 51. In this case, the assembled door structure can be used as a hidden door. Thus, one profile can meet multiple usage requirements, further enhancing its applicability.

[0052] like Figure 8As shown, when the second break portion 1116 is broken, the first profile 111 will not obstruct the first end cap 51. The range of motion of the first end cap 51 increases, and the position of the first end cap 51 can be adjusted. By limiting the first end cap 51 with the first limiting strip 511 of the first end cap 51 and the first limiting strip 1113a of different heights, the first end cap 51 can form a limiting space of different depths with the upper surface of the first profile 111, thus adapting to the first panel 3 of different thicknesses. This function can be achieved with a single profile, greatly improving applicability.

[0053] Example 3 Figure 9 The diagram schematically illustrates an assembled door structure according to another embodiment of the present invention.

[0054] like Figure 9 As shown, the assembled door structure is basically the same as that of Embodiment 2, except that the structure of the end cap 5 is different.

[0055] like Figure 9 As shown, the two ends of the end cap 5 are formed with second folded edges that are matched and limit the first panel 3 and the second panel 4.

[0056] Example 4 Figure 10 The diagram schematically illustrates an assembled door structure according to another embodiment of the present invention.

[0057] The assembled door structure is basically the same as that of Example 3, except that: (1) the structure of the profile is different; (2) the structure of the end cap 5 is different.

[0058] like Figure 10 As shown, in this embodiment, the first profile 111 does not include the first folded edge 1114, the first broken portion 1115, and the second broken portion 1116, and the two ends of the first profile 111 in the length direction are directly aligned with the first panel 3.

[0059] Furthermore, the main body of the end cap 5 in embodiments 1-3 is right-angled, while the main body of the end cap 5 in this embodiment is planar.

[0060] Example 5 Figure 11 The diagram schematically illustrates an assembled door structure according to one embodiment of the present invention.

[0061] like Figure 11 As shown, the structure of this assembled door structure is basically the same as that of Embodiment 4, except that the structure of the limiting part of the profile is different.

[0062] like Figure 11As shown, the outermost first protrusion 1111 includes a first straight section 1111c, and the first limiting part 1113 includes a plurality of stepped and spaced first limiting strips 1113a disposed on the first straight section 1111c; the outermost second protrusion 1121 includes a second straight section, and the second limiting part includes a plurality of stepped and spaced second limiting strips disposed on the second straight section; the outermost third protrusion 1211 includes a third straight section 1211c, and the third limiting part 1213 includes a plurality of stepped and spaced third limiting strips 1213a disposed on the third straight section 1211c; the outermost fourth protrusion 1221 includes a fourth straight section, and the fourth limiting part includes a plurality of stepped and spaced fourth limiting strips disposed on the fourth straight section.

[0063] 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 features a novel frame 1, which includes a first frame 11 and a second frame 12. The first frame 11 and the second frame 12 are detachably coupled and locked in place by a limiting member 13. Under external force, the 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 limiting member 13, thus completing 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 move closer to each other and press the core 2 in the middle, thereby enhancing the connection strength. This structure of the 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, mechanized pressing work, greatly shortening the construction period. 2. 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 transporting the panel, thus avoiding the risk of damage during panel transportation.

[0064] 3. 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, which is highly applicable and greatly reduces the inventory pressure, production costs, and transportation costs of profile manufacturing plants.

[0065] 4. 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.

[0066] 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.
