Description

Technical Field

[0001] This utility model relates to the field of door frame technology, specifically to a door frame structure. Background Technology

[0002] In the door manufacturing industry, hinged doors are a common type of door, widely used in residential and commercial buildings and various interior decorations. Hinged doors open inwards or outwards, and different opening methods have different impacts on space utilization and ease of passage.

[0003] The difference in opening direction presents a challenge to the structural design of hinged door frames. The structural design of the door frame needs to match the opening method of the door leaf. Therefore, conventional door frame designs on the market often require setting up various different structures according to the opening method of the door leaf (such as outward or inward opening).

[0004] However, due to the diverse structures of door frames, different corner brackets are required for different door frame structures. As a key component connecting the door frame to the wall and the door leaf, the compatibility of the corner bracket directly affects the installation efficiency and stability of the door. However, due to the diversity of door frame structures, the types and specifications of corner brackets have also increased accordingly, which increases the production cost of the corner brackets.

[0005] Given the above background, there is an urgent need in the market for a new door frame design solution that can improve the adaptability of door frame structures and reduce production and processing costs. Utility Model Content

[0006] The purpose of this utility model is to provide a door frame structure. By improving the structure of the door frame, the adaptability of the door frame structure is improved and the production and processing costs are reduced.

[0007] To achieve the above objectives, this utility model provides a door frame structure, including several types of main door frames adapted to door leaf structures that open in both directions. Each type of main door frame is defined to have a horizontal main door frame extending along the width direction of the door leaf structure and a vertical main door frame extending along the height direction of the door leaf structure. The two ends of the horizontal main door frame are connected to the ends of the corresponding vertical main door frame via L-shaped corner brackets. Each type of main door frame is provided with a corner bracket cavity for adapting to the L-shaped corner brackets, and the dimensions of each corner bracket cavity are consistent.

[0008] By adopting the method in this application, the main door frames are divided into several types according to the opening direction of the door leaf structure. The corner bracket cavity size of the main door frames is the same. Therefore, no matter what the opening direction of the door leaf structure is, the main door frame in this application can be adapted to the same type of corner bracket, thereby improving the adaptability of the door frame structure and reducing the production and processing costs.

[0009] Optionally, the main door frame is provided with a receiving cavity, and a portion of the cavity wall protrudes inward to form a first protrusion and a second protrusion spaced apart; the cavity wall of a portion of the receiving cavity, the first protrusion, and the second protrusion together enclose and define the corner bracket cavity. This method of defining the corner bracket cavity with two protrusions within the receiving cavity releases the design possibilities of the receiving cavity itself and further improves the adaptability of the door frame structure.

[0010] Optionally, the main door frame includes a first plate and a second plate opposite to each other in the width direction, and a third plate and a fourth plate connected between the first plate and the second plate, with at least a portion of the first plate, a portion of the second plate, the third plate, and the fourth plate forming the receiving cavity. Thus, the receiving cavity, formed by the box-shaped structure of the aforementioned plates, has a strong load-bearing capacity and can support door leaf structures of greater weight.

[0011] Optionally, one of the first protrusion and the second protrusion is disposed on the third plate, and the other is disposed on the fourth plate. In this way, the first plate, the first protrusion, and the second protrusion together form a corner code cavity.

[0012] Optionally, a type of main door frame is defined as having the first protrusion disposed on the third plate and the second protrusion disposed on the side of the second plate away from the third plate.

[0013] The first protrusion of the main door frame is located on the fourth plate, and the second protrusion is located on the side of the second plate away from the fourth plate; these are defined as type II main door frames. By adopting this method, the positions of the first and second protrusions can be matched according to the opening direction of the door leaf structure, thus further improving the adaptability of several types of main door frames and reducing production and processing costs.

[0014] Optionally, the door frame structure further includes a door stop, which is fixedly connected to the second protrusion. This utilizes the second protrusion to fix the door stop, improving the integration of the main door frame.

[0015] Optionally, the second plate is further provided with a baffle, which abuts against the door stop in the thickness direction of the door leaf structure. By setting the baffle to limit the door stop in the thickness direction of the door leaf structure, the structural strength of the door stop can be improved.

[0016] Optionally, the first type of main door frame includes a first edge-sealing cavity, and the second type of main door frame further includes a second edge-sealing cavity; the door frame structure also includes an edge-sealing component, which has a plug-in portion, and the first edge-sealing cavity and the second edge-sealing cavity have the same dimensions and can both be plugged into the plug-in portion. Thus, these various types of main door frames can all be adapted to edge-sealing components with plug-in portions of the same size, further improving the adaptability of the door frame structure.

[0017] Optionally, the third plate forms the bottom wall of the first edging cavity; the baffle forms the bottom wall of the second edging cavity. This improves the integration of the main door frame.

[0018] Optionally, both the first and second plates extend into the doorway along the thickness direction of the door structure, exceeding the third plate; the portions of the first and second plates located outside the receiving cavity, together with the third plate, form an insert cavity; the insert cavities of all types of main door frames have the same dimensions in the width direction of the door structure. Thus, regardless of the opening direction of the door structure, all types of main door frames can accommodate panels of the same thickness.

[0019] Optionally, it also includes an auxiliary door frame that is adapted to the main door frame in the thickness direction of the door leaf structure; the auxiliary door frame has an adaptation cavity that is opposite to the insert cavity in the thickness direction, and the dimensions of the adaptation cavity are consistent with those in the width direction of the door leaf structure. In this way, when an auxiliary door frame is required, the auxiliary door frame can also be adapted to a board of the same thickness.

Detailed Implementation

[0052] This utility model provides a door frame structure. By improving the structure of the door frame, the adaptability of the door frame structure is improved and the production and processing costs are reduced.

[0053] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0056] The door frame structure includes several types of main door frames to accommodate door leaf structures that open in both directions. Each type of main door frame is defined to have a horizontal main door frame extending along the width direction of the door leaf structure and a vertical main door frame extending along the height direction of the door leaf structure. The two ends of the horizontal main door frame are connected to the ends of the corresponding vertical main door frame by L-shaped corner brackets. Each type of main door frame is provided with a corner bracket cavity 206 to accommodate the L-shaped corner brackets, and the dimensions of each corner bracket cavity 206 are the same.

[0057] By adopting the method in this application, the main door frames are divided into several types according to the opening direction of the door leaf structure. The corner bracket cavity 206 of the several types of main door frames has the same size. Therefore, no matter what the opening direction of the door leaf structure is, the main door frame in this application can be adapted to the same type of corner bracket, thereby improving the adaptability of the door frame structure and reducing the production and processing costs.

[0058] In a specific example, the main door frame is provided with a receiving cavity 207. The main door frame includes a first plate 201 and a second plate 202 opposite to each other in the width direction, and a third plate 203 and a fourth plate 204 connected between the first plate 201 and the second plate 202. At least a portion of the first plate 201, a portion of the second plate 202, the third plate 203, and the fourth plate 204 enclose the receiving cavity 207. Thus, the receiving cavity 207 is a box-shaped structure enclosed by the aforementioned plates. Such a structure has strong load-bearing capacity and can support door leaf structures with greater weight.

[0059] A portion of the cavity wall of the receiving cavity 207 protrudes inward to form a first protrusion 208 and a second protrusion 209 spaced apart. The cavity wall of the portion of the receiving cavity 207, the first protrusion 208, and the second protrusion 209 together enclose and define the corner bracket cavity 206. This method of defining the corner bracket cavity 206 by setting two protrusions within the receiving cavity 207 releases the design possibilities of the receiving cavity 207 itself and further improves the adaptability of the door frame structure.

[0060] In one example, one of the first protrusion 208 and the second protrusion 209 is disposed on the third plate 203, and the other is disposed on the fourth plate 204. In this way, the first plate 201, the first protrusion 208, and the second protrusion 209 together form the corner code cavity 206.

[0061] In another example, a main door frame 200-1 is defined as having a first protrusion 208 located on the third plate 203 and a second protrusion 209 located on the side of the second plate 202 away from the third plate 203; a main door frame 200-2 is defined as having a first protrusion 208 located on the fourth plate 204 and a second protrusion 209 located on the side of the second plate 202 away from the fourth plate 204. The second protrusion 209 has a limiting surface parallel to the first plate 201 and located on the same plane as the limiting surface of the first protrusion 208. This defines the diagonal code cavity 206.

[0062] By adopting this method, the positions corresponding to the first protrusion 208 and the second protrusion 209 can be matched according to the opening direction of the door leaf structure, which further improves the adaptability of several types of main door frames and reduces production and processing costs.

[0063] In the example above, the door frame structure also includes a door stop 700, which is fixedly connected to the second protrusion 209. Specifically, a snap-fit ​​cavity is provided on the outer side of the second protrusion, and the snap-fit ​​cavity engages with a portion of the door stop 700. Thus, the door stop 700 is fixed using the second protrusion 209, improving the integration of the main door frame.

[0064] To enhance the structural strength of the doorstop 700, the second plate 202 is further provided with a baffle 205, which abuts against the doorstop 700 in the thickness direction of the door leaf structure. The baffle 205 is disposed on the second plate 202 and extends in a direction parallel to the third plate 203 or the fourth plate 204 away from the wall 600. By limiting the doorstop 700 in the thickness direction of the door leaf structure with the baffle 205, the structural strength of the doorstop 700 can be improved.

[0065] In the above embodiments, a type 1 main door frame 200-1 includes a first edge-sealing cavity 213-1, and a type 2 main door frame 200-2 further includes a second edge-sealing cavity 213-2. The door frame structure also includes an edge-sealing member 210, which has a plug-in portion 211 that inserts into the corresponding edge-sealing cavity along the thickness direction. The first edge-sealing cavity 213-1 and the second edge-sealing cavity 213-2 have the same dimensions and can both be plugged into the plug-in portion 211. Therefore, these types of main door frames can all be adapted to edge-sealing members 210 with plug-in portions 211 of the same size, further improving the adaptability of the door frame structure.

[0066] In the various embodiments described above, the first plate 201 and the second plate 202 both extend into the doorway along the thickness direction of the door leaf structure, exceeding the third plate 203; the portions of the first plate 201 and the second plate 202 located outside the receiving cavity 207, together with the third plate 203, form the insert cavity 212; the insert cavity 212 of each type of main door frame has the same dimension in the width direction of the door leaf structure. Therefore, regardless of the opening direction of the door leaf structure, each type of main door frame can accommodate panels of the same thickness.

[0067] Optionally, it also includes an auxiliary door frame 300 that is adapted to the main door frame in the thickness direction of the door leaf structure; the auxiliary door frame 300 has an adaptation cavity 301 that is opposite to the insert cavity 212 in the thickness direction, and the dimensions of the adaptation cavity 301 are consistent in the width direction of the door leaf structure. In this way, when the auxiliary door frame 300 is required, the auxiliary door frame 300 can also be adapted to the same thickness of the board.

[0068] The technical solutions of this application are further explained below through several more detailed specific embodiments. It should be noted that these two embodiments are for illustrative purposes only and are not intended to limit the scope of the technical solutions of this application. Those skilled in the art can combine the following two embodiments with the previous embodiments in part or in whole, and all technical solutions derived from such combinations fall within the protection scope of this patent.

[0069] Example 1

[0070] Please refer to Figures 1-7Understandably, in this embodiment, the structure of a type of main door frame 200-1 will be specifically described. In various examples of a type of main door frame 200-1, depending on the type of outer decorative panel 400, an extension plate 213 is formed by extending the end of the baffle 205 away from the receiving cavity 207 outward to the outside of the door opening. The extension plate 213 extends beyond the fourth plate 204 in the thickness direction of the door leaf structure, and the dimension of the extension plate 213 in the thickness direction is adapted to the thickness of the outer decorative panel 400.

[0071] In one example, the exterior decorative panel 400 includes a gypsum board layer 401 and a putty layer 402 stacked sequentially along the thickness direction. The gypsum board abuts against the outer wall surface of the fourth panel 204 and presses against the side wall of the extension panel 213 in the width direction. The end of the extension panel 213 is provided with a barbed flange to accommodate the putty layer 402.

[0072] In another example, the exterior decorative panel 400 includes a hanging plate 403; in this embodiment, the baffle 205 extends outward in the width direction. During the fixing of a main door frame 200-1 to the wall 600, the baffle 205 forms a gap between the wall 600 in the thickness direction and the wall surface of the wall 600. The hanging plate 403 can be inserted and adapted to fit into this gap and between the baffle 205 and the extension plate 213. At this time, the end of the extension plate 213 is provided with an L-shaped bend to limit the outer side of the hanging plate 403.

[0073] Of course, in examples where the exterior decorative panel 400 is not required, one type of main door frame 200-1 also includes a generally L-shaped edge banding 214, with the outer edge of the first panel 201 along its thickness direction aligned with the end of the extension panel 213; the edge banding 214 includes a horizontal edge parallel to the wall 600 and a side edge perpendicular to the wall 600, the horizontal edge pressing against the ends of the extension panel 213 and the first panel 201 and covering the gap between the first panel 201 and the extension panel 213. Simultaneously, the side edge presses against the wall 600 to partially wrap the wall 600. Those skilled in the art can also adjust the length of the horizontal edge as needed to achieve coverage of different sizes of the wall 600.

[0074] In any of the above embodiments, the main door frame 200-1 may also include two cases: one with an edge banding 210 or without an edge banding 210. In the example of this application, the first edge banding cavity 213-1 and the insert plate cavity 212 are the same cavity, which can further improve the integration of the main door frame 200-1.

[0075] When the edge-sealing component 210 is required, a type of main door frame 200-1 also has a first edge-sealing cavity 213-1. The insertion part 211 of the edge-sealing component 210 is inserted into the first edge-sealing cavity 213-1 (insertion plate cavity 212). The portion of the insertion part 211 extending out of the first edge-sealing cavity 213-1 extends toward the wall 600 and presses against the end of the first plate 201 in the thickness direction. The third plate 203 constitutes the cavity bottom wall of the first edge-sealing cavity 213-1.

[0076] The insertion part 211 has a first insertion wall, a second insertion wall, and a transition wall connecting the two insertion walls. The end of the first plate 201 extends beyond the third plate 203, and the end of the second plate 202 extends beyond the third plate 203, with the first plate 201 extending beyond the end of the second plate 202. The first insertion wall is inserted into and adapted to the first plate 201, and the second insertion wall is inserted into and adapted to the second plate 202. The distance between the first insertion wall and the third plate 203 is greater than the distance between the second insertion wall and the third plate 203. The transition plate is sloped. When the first edge-sealing cavity 213-1 (insertion plate cavity 212) is not provided with the edge-sealing part 210, an outer wall panel 500 is inserted into and adapted to the insertion plate cavity 212. The outer wall panel 500 is used to cover part of the wall 600, and the outer wall panel 500 can be an aluminum honeycomb panel.

[0077] In order to adapt to the other end of the outer wall panel 500, an auxiliary door frame 300 is also provided. The auxiliary door frame 300 has an adaptation cavity 301 and an extension extending from the adaptation cavity 301. The extension is used to abut against the wall 600 and cover the wall 600. Those skilled in the art can set the size of the extension as needed.

[0078] Example 2

[0079] Please refer to Figures 8-15 Understood. The structure of the second-class main door frame 200-2 will be explained below. The difference between the second-class main door frame 200-2 and the first-class main door frame 200-1 is that the baffle 205 is located at the end of the second plate 202 away from the fourth plate 204. The extension plate 213 is not formed by extending the baffle 205, but rather by extending the second plate 202 beyond the fourth plate 204. The part of the second plate 202 that extends beyond the fourth plate 204 serves as the extension plate 213. The connection method between the outer decorative panel 400 and the second-class main door frame 200-2 can be understood by referring to the first-class main door frame 200-1.

[0080] The difference between the Class II main door frame 200-2 and the Class I main door frame 200-1 lies in the fact that the Class II main door frame 200-2 has a second edge-sealing cavity 213-2, which is located beside the insert plate cavity 212, rather than sharing a single cavity. Specifically, in the Class II main door frame 200-2, the portions of the first plate 201 and the second plate 202 that extend beyond the third plate 203 are the same as in the Class I main door frame 200-1. The difference is that the baffle 205 is located on the portion of the second plate 202 that does not extend beyond the third plate 203. The baffle 205 also has a limiting plate 215 parallel to the second plate 202. The limiting plate 215, the baffle 205, and part of the second plate 202 together define the second edge-sealing cavity 213-2. The baffle 205 forms the bottom wall of the second edge-sealing cavity 213-2. When the edging piece 210 is required, the insertion part 211 is inserted into the second edging cavity 213-2. One end of the insertion part 211 extends towards the wall 600 and abuts against the end of the first plate 201 to seal the insertion cavity 212. When both the edging piece 210 and the outer wall panel 500 are installed, an opening can be made in the portion of the edging piece 210 covering the insertion cavity, and the outer wall panel 500 can be inserted into the insertion cavity through the opening. Alternatively, the insertion part 211 can extend partially to abut against the outer wall panel 500. In the example of installing the outer wall panel 500, the structure of the auxiliary door frame 300 can be understood with reference to the structure in Embodiment 1.

[0081] Compared with the prior art, the technical solution of this application has the following advantages:

[0082] In the technical solution of this application, the main door frame is divided into two categories according to the opening direction of the door leaf structure, namely, the first type of main door frame 200-1 and the second type of main door frame 200-2. This significantly improves the adaptability of the door frame structure, enhances the universality of the door frame structure adapters, and reduces production and processing costs.

[0083] As another aspect of this application, a door leaf structure is also provided; please refer to... Figures 16 to 25 As shown, Figure 16 This is one of the partial structural diagrams of the door leaf structure in an embodiment of this utility model, showing the door frame beam used for 90° assembly; Figure 17 This is the second partial structural schematic diagram of the door leaf structure in an embodiment of this utility model, showing the door frame beam used for 45° assembly; Figure 18 This is one of the cross-sectional views of the door panel structure; Figure 19 This is the second cross-sectional view of the door structure; Figure 20 This is the third cross-sectional view of the door structure; Figure 21 This is the fourth cross-sectional view of the door structure; Figure 22 yes Figure 18 Vertical section view of the door leaf structure; Figure 23 yes Figure 19 Vertical section view of the door leaf structure; Figure 24 yes Figure 20 Vertical section view of the door leaf structure; Figure 25 yes Figure 21 Vertical section view of the door leaf structure.

[0084] The door structure includes a door frame beam 100, which supports the door structure and forms its outline. Specifically, the portion of the door frame beam 100 extending along the height of the door structure is defined as a vertical beam, and the portion extending along the width of the door structure is defined as a horizontal beam. The door structure typically has two vertical beams and two horizontal beams, with the two horizontal beams connected between the two vertical beams or vice versa, forming a rectangular frame.

[0085] The door frame beam 100 has two support plates 101 distributed opposite each other along the thickness direction of the door leaf structure, and the extension direction of the support plates 101 is the width direction of the door leaf structure. Each support plate 101 has a first end 101a and a second end 101b in its extension direction. The two first ends 101a and the two second ends 101b are opposite each other in the width direction. The door leaf structure also includes a first type of plate 103 and a second type of plate 104. The first type of plate 103 abuts against the two first ends 101a, and the second type of plate 104 abuts against the two second ends 101b to cover the sides of the door leaf structure. The two first ends 101a are aligned, and the two second ends 101b are staggered in their extension directions. Alignment means that the two first ends 101a are located in the same plane, and staggering means that one second end 101b extends beyond the other second end 101b in the extension direction of the support plate 101, i.e., the width direction of the door leaf structure. During installation, the first end 101a or the second end 101b is positioned outwards to serve as the side of the door structure.

[0086] Specifically, both type I panel 103 and type II panel 104 include a panel body, which covers the end of the door frame beam 100 on the corresponding side. The panel body of type I panel 103 is a straight wall; the panel body of type II panel 104 has a Z-shaped structure. This allows for the setting of the clearance space according to the opening direction of the door leaf.

[0087] In one specific implementation, the second-class plate 104 has a recessed clearance groove 104-1, which is used to fit the door stop. The clearance groove 104-1 defines a clearance space, and different clearance space requirements can be adapted by adjusting the size of the clearance groove 104-1 of the second-class plate 104. When the size of the clearance groove 104-1 remains the same, different opening directions of the door leaf structure can be adapted simply by adjusting the installation method of the door frame beam 100.

[0088] When the second end 101b is positioned outwards as a side of the door leaf structure, the body of the second-class plate 104 has a first plate segment, a second plate segment, and a third plate segment. The first and third plate segments extend along the thickness direction and abut against the corresponding second end 101b. The second plate segment connects the first and third plate segments. The outer sides of the second and third plate segments are recessed relative to the first plate segment to form a clearance groove 104-1, which is adapted to fit the door stop. If the clearance groove 104-1 is not required, the installation position of the door frame beam 100 can be adjusted so that the first end 101a faces outwards as a side of the door leaf structure. Here, "inner" and "outer" are defined with reference to the door leaf structure. In the width direction of the door leaf structure, the side pointing towards the center of the door leaf structure is considered inner, and vice versa.

[0089] To provide support for the two support plates 101, at least one connecting plate 102 is connected between the two support plates 101, and the connecting plate 102 extends along the thickness direction. The connecting plate 102 is arranged perpendicular to the support plate 101 and is welded and fixed to the support plate 101.

[0090] By adopting the technical solution of this application, the second ends 101b of the two support plates 101 of the door frame beam 100 are staggered in their extension direction, and the second type plate 104 is used to abut against the second ends 101b, thereby forming a clearance space; at the same time, the first ends 101a are aligned in their extension direction, and the first type plate 103 abuts against the first ends 101a, so that by changing the installation direction of the door frame beam 100, the clearance space can be formed in any direction of the door leaf structure. This allows the structure of the door frame beam 100 to be frequently changed according to the different opening directions of the door leaf, greatly reducing production costs, improving installation efficiency, and enhancing the versatility of the product.

[0091] In the example shown, the door frame beam 100 includes two opposing connecting plates 102 along the extending direction of the support plate 101. The two adjacent connecting plates 102 and a portion of the support plate 101 form a support cavity 106. The support cavity 106 can be rectangular or square, etc. By providing the support cavity 106, the load-bearing capacity of the door frame beam 100 is improved, thus enhancing its structural strength.

[0092] The assembly method of the door frame beam 100 of this application will be described in detail below.

[0093] In the technical solution of this application, the vertical beam and the horizontal beam are assembled at a 90° angle; or, the vertical beam and the horizontal beam are assembled at a 45° angle. The door structure of this application can adapt to both assembly methods, making the assembly method more flexible and further improving its adaptability.

[0094] 90° assembly method

[0095] In one specific embodiment, a first-type connection structure 107 and a second-type connection structure 108 are located within a support cavity 106. The first-type connection structure 107 forms a first connection cavity 107a, and the second-type connection structure 108 forms a second connection cavity 108a. The first-type connection structure 107 is a threaded hole portion adapted to fit a screw, and the first connection cavity 107a is used to insert and accommodate the screw. The second-type connection structure 108 is a corner bracket insertion hole portion adapted to fit a corner bracket, and the second connection cavity 108a is used to insert and accommodate the corner bracket.

[0096] The first connecting cavity 107a is located on the connecting plate 102, and the second connecting cavity 108a is located on the support plate 101. When the vertical beam and the horizontal beam are assembled at 90°, the two first connecting cavities 107a and the two second connecting cavities 108a are centrally symmetrically distributed. Here, central symmetry means that they are symmetrical along the center of the support cavity 106.

[0097] In the example shown, both first connecting cavities 107a are located on the outer side of the connecting plate 102, that is, on the side further away from the centerline of the connecting plate 102. The centerline of the connecting plate 102 extends along the width direction of the door structure and passes through the midpoint of the connecting plate 102 in the thickness direction of the door structure. The two second connecting cavities 108a are located at the junction of the connecting plate 102 and the support plate 101.

[0098] In the actual assembly process, the crossbeam is vertically pressed against the end of the vertical beam, or the vertical beam is positioned outside the crossbeam and pressed against the end of the crossbeam. Then, a screw passes through the first connecting cavity 107a of the crossbeam and vertical beam and is threadedly connected to a type-one connecting structure 107. Simultaneously, an angle bracket passes through the second connecting cavity 108a of the crossbeam and vertical beam and connects to a type-two connecting structure 108. This further increases the variety of connection methods in the 90° assembly scheme, further enhancing adaptability.

[0099] 45° assembly method

[0100] In this configuration, only a second type of connection structure 108 located within the support cavity 106 is provided, which forms a second connection cavity 108a. The second type of connection structure 108 can be adapted to an L-shaped bracket to allow the vertical beam and the horizontal beam to be assembled.

[0101] The second connecting cavity 108a is located on the support plate 101; when the vertical beam and the horizontal beam are assembled at a 45° angle, the second connecting cavities 108a are relatively distributed along the width direction of the door structure. That is, the two second connecting cavities 108a are symmetrically arranged along the centerline of the connecting plate 102. Thus, when assembled at a 45° angle, the connection between the horizontal beam and the vertical beam can be achieved.

[0102] The following is a detailed explanation of the installation method of the door panel 109 in the door structure.

[0103] The door structure also includes a door panel 109, which covers the door beam frame to form the external shape of the door structure.

[0104] Specifically, both ends of the first-type plate 103 and the second-type plate 104 extend beyond the door frame beam 100 along the thickness direction, thereby reserving space for the installation of the door panel 109 of the door leaf structure. Specifically, the door panel 109 has two first panel walls opposite each other along the width direction of the door leaf structure and two second panel walls opposite each other along the thickness direction of the door leaf structure. The first panel walls abut against the portion of the first-type plate 103 or the second-type plate 104 extending beyond the door frame beam on the corresponding side in the width direction, and the second panel walls press against the outer wall of the support plate 101 in the width direction, thereby supporting the door panel 109.

[0105] The end of the first type of board 103 or the second type of board 104 forms a flange 105 to press against a part of the second panel wall, thereby forming an edge of the door panel 109. At this time, the flange 105 extends in a straight line; or it can extend slightly beyond the door panel 109 in the thickness direction to perform a puttying operation on the door panel 109. At this time, the flange 105 has a barbed structure to reserve space for filling the putty.

[0106] The size of the first-class board 103 or the second-class board 104 is the same as that of the corresponding side support board 101, thereby enabling it to adapt to door panel 109 of the same thickness, thus further improving the adaptability of the door structure.

[0107] The following provides a further explanation of how the first-class plate 103 and the second-class plate 104 are connected to the support plate 101.

[0108] In the above embodiments, both type I plate 103 and type II plate 104 include a plate body and two connecting beams opposite each other along the thickness direction; the connecting beams are inserted into the inner side of the two support plates 101 and stop against the inner sidewall of the support plate 101 in the extension direction of the support plate 101.

[0109] In this way, the first type of plate 103 and the second type of plate 104 are inserted into the support plate 101, and this connection method facilitates the processing of the door body.

[0110] In another embodiment, the inner sidewalls of the first end 101a and the second end 101b of the two support plates 101 are provided with a serrated structure; the outer sidewalls of the connecting beam are also provided with a serrated structure. This increases the connection strength between the first type plate 103 and the second type plate 104 in the extension direction of the support plate 101.

[0111] In the aforementioned embodiments, the door frame of the door leaf structure is made of aluminum alloy, and the first-class panel 103 and the second-class panel 104 are also made of aluminum alloy. A graphite homogeneous plate is filled inside the door frame beam 100 to further support the door leaf structure, and the door leaf panel 109 is made of high-density door skin. The aluminum alloy door frame, the first-class panel 103, and the second-class panel 104, due to their material properties and cavity shape, provide a certain degree of anti-deformation for tall doors. Furthermore, the sound insulation coefficient of the graphite homogeneous plate is basically the same as that of traditional door core panels (bridge-hole mechanical panels), and superior to common aluminum honeycomb panels. Therefore, the sound insulation effect of this product is higher than that of existing similar products, providing users with a quieter and more comfortable home life.

[0112] Compared with existing door leaf structures, the technical solution of this application has the following advantages:

[0113] First, the door frame beam 100 in this application has a high degree of adaptability. In the production of door leaf structures, manufacturers can choose door frame beams 100 that are compatible with their respective production stages for assembly. They can freely choose 90° or 45° assembly according to the different production stages of each factory, and can use the same corner bracket for adaptation, thereby further reducing the production costs of manufacturers;

[0114] Secondly, as an optional method, if the door panel 109 is edge-wrapped, a 9 mm thick panel can be used; if it is puttyed, an 8 mm thick door panel 109 can be used. This allows it to cooperate with the door frame, making it sturdy and durable.

[0115] Third, the door leaf structure in this application improves sound insulation to a certain extent. The aluminum alloy material used for the door beam frame also makes the door leaf structure more stable and less prone to deformation, thus meeting customers' requirements for a user-friendly and durable door.

[0116] Fourth, by adopting the technical solution of this application, the second ends 101b of the two support plates 101 of the door frame beam 100 are staggered in their extension direction, and a secondary plate 104 is used to abut against the second ends 101b, thereby forming a clearance space. Simultaneously, the first ends 101a are aligned in their extension direction, and a secondary plate 103 abuts against the first ends 101a. This allows for the creation of clearance space in any direction of the door leaf structure by changing the installation direction of the door frame beam 100. This enables frequent modifications to the structure of the door frame beam 100 according to different opening directions of the door leaf, significantly reducing production costs, improving installation efficiency, and enhancing product versatility. A single door leaf structure can be used in different opening directions, and double doors, mother-daughter doors, etc., can be made simultaneously.

It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
