Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to an aluminum frame glass door panel with concealed nail holes. Background Technology

[0002] Compared to traditional wooden door panels, aluminum-framed glass door panels offer significant advantages in performance and aesthetic value thanks to their unique material combination and innovative manufacturing processes. Firstly, the aluminum alloy frame utilizes high-strength profiles and a multi-cavity structure design, increasing bending resistance by 3-5 times compared to wooden frames. Combined with the zero-expansion characteristics of tempered glass, this effectively avoids the deformation and cracking problems that wooden door panels are susceptible to due to temperature and humidity fluctuations, making it particularly suitable for high-humidity environments (such as kitchens and bathrooms). Secondly, anodizing or fluorocarbon coating processes give the aluminum surface excellent wear and corrosion resistance, extending its lifespan by more than twice that of wooden door panels, and eliminating the need for regular painting maintenance. Visually, the combination of transparent glass and a narrow metal frame (as thin as 8mm) breaks through the solid, enclosed feel of wooden door panels, creating a modern minimalist aesthetic through light refraction and spatial extension. It also supports customized surface treatments such as gradient glaze and intelligent frosting, achieving a deep integration of function and decoration. In addition, the modular aluminum profile structure is also an outstanding highlight in terms of its environmental friendliness throughout its entire life cycle. The aluminum alloy can be 100% recycled and reused, avoiding the formaldehyde release and resource consumption problems of wood panels, which is in line with the development trend of green home furnishing.

[0003] Despite advancements in technology that prioritize minimalist aesthetics and structural strength, existing aluminum-framed glass door panels still suffer from the core pain point of exposed nail holes, which negatively impact overall appearance. Traditional installation methods rely on screws or corner brackets for mechanical fixation of aluminum profiles, resulting in visible nail holes or seams on the frame surface. This is particularly problematic in ultra-narrow frame designs (≤15mm), where the lack of effective concealment makes these holes even more unsightly, disrupting the "seamless" visual experience of the door panel. While some solutions attempt to cover these holes with adhesive filling or decorative frame strips, long-term use can lead to issues such as adhesive aging and discoloration, and cover plate detachment, and these issues are difficult to match the metallic texture of high-precision anodized surfaces. Furthermore, the presence of nail holes creates weak points for dust accumulation and moisture intrusion, indirectly affecting sealing performance. The industry is exploring pre-embedded nut structures, magnetic splicing processes, or nail-free adhesive bonding technologies to eliminate exposed fasteners, but due to limitations in aluminum alloy profile processing precision, connection strength, and cost control, a universally applicable solution has yet to be developed. This technological bottleneck restricts the penetration rate of aluminum-framed glass door panels in the high-end customized home furnishing market, and is therefore a technical problem that urgently needs to be solved in this field.

[0004] Chinese patent document (patent application number: 202323456433.1, application date: 2023.12.19) discloses a minimalist glass door, referencing... Figure 1 As shown, Figure 1This is a schematic diagram of the overall structure of a glass door from a Chinese patent document. The minimalist glass door includes a frame 100' and a glass core panel 200'. The glass core panel 200' is fixed inside the frame 100'. A circular hole is provided on the side of the glass core panel 200' near the door handle. The circular hole is for a handle assembly 300'. The handle assembly 300' includes a first split component and a second split component. The first split component has external threads and a slot, while the second split component has internal threads. The inner side of the second split component also has an inner cavity groove for inserting fingers to open the door. The first and second split components are respectively inserted from both sides of the glass core panel 200'. The door handle assembly is completed by threaded connection. After assembly, the slot and the inner cavity are interconnected. When opening the door, a finger can be inserted through the slot on one side of the first split component, and then the door can be hooked out by using the step between the inner side of the inner wall groove and the groove opening. After installation, the first split component is located on the outer surface of the glass core panel 200' and is almost flush with it. The second split component is located on the inner surface of the glass core panel 200' and is flush with the thickness of the frame 100'. The second split component is located inside the cabinet, so the handle assembly 300' can be hidden. This application does not hide the nail holes opened at each top corner, that is, it does not solve the above-mentioned technical problem. Utility Model Content

[0005] In view of this, the present invention provides an aluminum frame glass door panel with concealed nail holes to solve the problem in the prior art where the presence of nail holes becomes a weak point for dust accumulation or moisture intrusion, indirectly affecting the sealing performance.

[0006] This application provides an aluminum-framed glass door panel with concealed nail holes, including a door leaf frame and a border decorative strip, wherein...

[0007] The door frame includes a first side, a second side, a third side, and a fourth side that are connected in sequence and form a rectangular frame. The first side is parallel to the third side, the second side and the fourth side are parallel and symmetrically arranged, and the first side is perpendicular to the second side.

[0008] The first, second, third, and fourth borders each include a border receiving member and a border connecting member with a hollow quadrilateral cross-section. The border receiving member includes a first receiving side plate, a second receiving side plate, a third receiving side plate, and a fourth receiving side plate connected sequentially to form a hollow quadrilateral. The first receiving side plate is parallel to the third receiving side plate, and the second and fourth receiving side plates are parallel to each other. The first receiving side plate intersects with the second receiving side plate. A first U-shaped structure is provided on the side of the third receiving side plate away from the first receiving side plate, with the opening of the first U-shaped structure away from the first receiving side plate. A step member is connected to the side of the second receiving side plate away from the first receiving side plate, with the step surface of the step member facing the first U-shaped structure. Along the direction from the second border to the fourth border, the length of the step member in the first and third borders is greater than the length of the first U-shaped structure in the first and third borders. Along the direction from the first border to the third border, the length of the step member in the second and fourth borders is greater than the length of the first U-shaped structure in the second and fourth borders.

[0009] The frame connector includes an L-shaped member and an inverted T-shaped member. The L-shaped member is connected to the side of the first receiving side plate away from the second receiving side plate. The inverted T-shaped member is connected to the side of the fourth receiving side plate away from the second receiving side plate. The inverted T-shaped member and part of the fourth receiving side plate form a second C-shaped structure. The opening of the second C-shaped structure is opposite to the side of the L-shaped member.

[0010] At the points where the hollow quadrilateral of the first frame connects to the hollow quadrilateral of the second frame, the hollow quadrilateral of the second frame connects to the hollow quadrilateral of the third frame, the hollow quadrilateral of the third frame connects to the hollow quadrilateral of the fourth frame, and the hollow quadrilateral of the fourth frame connects to the hollow quadrilateral of the first frame, frame brackets are respectively inserted. Connecting holes are respectively opened on both sides of the third receiving side plate along its length direction. The connecting holes penetrate the third receiving side plate in the direction pointing from the third receiving side plate to the first receiving side plate. The orthographic projection of the connecting hole does not overlap with the orthographic projection of the first U-shaped structure, but completely overlaps with the frame bracket. Fasteners are connected to the frame brackets through the connecting holes.

[0011] The border decorative strip includes a first decorative profile, a second decorative profile, a third decorative profile, and a fourth decorative profile connected sequentially and forming a rectangular frame. The first decorative profile covers the first border, the second decorative profile covers the second border, the third decorative profile covers the third border, and the fourth decorative profile covers the fourth border. Each of the first, second, third, and fourth decorative profiles includes a first inverted F-shaped component and a second inverted F-shaped component integrally connected to the first inverted F-shaped component. The first inverted F-shaped component is located on the side of the second inverted F-shaped component closer to the step component. The first inverted F-shaped component includes a first inverted L-shaped portion and a first decorative snap-fit ​​portion connected to the first inverted L-shaped portion. The side of the first inverted L-shaped portion away from the second inverted F-shaped component contacts the step component. The first decorative snap-fit ​​portion snaps into the opening of the first C-shaped structure. The first inverted F-shaped component includes a second inverted L-shaped portion and a second decorative snap-fit ​​portion connected to the second inverted L-shaped portion. The second decorative snap-fit ​​portion snaps into the opening of the second C-shaped structure.

[0012] Compared with the prior art, the aluminum frame glass door panel with concealed nail holes provided by this utility model achieves at least the following beneficial effects:

[0013] Firstly, through the design of the first C-shaped structure, frame housing, frame connectors (such as L-shaped and inverted T-shaped pieces), and frame decorative strips, the first C-shaped structure, frame connectors, connecting holes, and fasteners are concealed internally. This avoids exposed connecting holes (such as nail holes), fasteners (bolts), or other connection marks, making the surface of the aluminum frame glass door panel cleaner and smoother. This not only matches the metallic texture of the high-precision anodized surface but also prevents dust accumulation or moisture intrusion at weak points such as connecting holes, thereby improving its sealing performance. The frame decorative strip covers the surface of the frame housing and the inverted T-shaped piece, preventing the frame housing and the inverted T-shaped piece from being exposed. The T-shaped component is protected from external scratches and damage, extending the lifespan of the door frame. The decorative border strip completely covers the door frame's frame housing and inverted T-shaped component, forming a unified rectangular frame that enhances visual uniformity and overall product aesthetics. Secondly, the first and second inverted F-shaped components simplify the structure of the first, second, third, and fourth decorative profiles, eliminating unnecessary decorations or protruding parts. The decorative border strip is securely fixed to the frame housing and inverted T-shaped component through the snap-fit ​​design of the first and second inverted F-shaped components, further strengthening the overall integrity of the door frame. Thirdly, the use of frame corner brackets and fasteners ensures a strong connection between the frame housing components, enhancing the structural strength of the entire door frame. The hollow quadrilateral structure of the frame housing reduces weight while providing sufficient support strength, ensuring that the aluminum frame glass door panel will not deform or be damaged during use. Fourth, the frame trim is fixed to the frame housing and the inverted T-shaped piece by a snap-fit ​​method, eliminating the need for bolts or other fasteners, greatly simplifying the installation process and reducing installation time and costs. The second C-shaped structure between the first C-shaped structure, the inverted T-shaped piece, and the frame housing provides a precise positioning function, ensuring that different decorative profiles can be installed quickly and accurately. The snap-fit ​​design of the first, second, third, and fourth decorative profiles allows for easy disassembly, facilitating the maintenance or replacement of the frame trim and door frame. If the first, second, third, and / or fourth decorative profiles are damaged, they can be replaced individually without replacing the entire frame trim, reducing maintenance costs.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

[0041] Specifically, the patent title of this utility model can also be "aluminum frame glass door panel". Combined with... Figure 2 , Figure 3 and Figure 5 As shown, the door frame 1 is formed by connecting the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 in sequence to form a rectangular frame. The first frame 11 is parallel to the third frame 13, the second frame 12 is parallel to the fourth frame 14 and is symmetrically arranged, and the first frame 11 is perpendicular to the second frame 12. The above design constitutes the basic structure of the aluminum frame glass door panel, providing support and shape foundation for the entire aluminum frame glass door panel.

[0042] Optionally, the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 can be made of aluminum, which is lightweight, high-strength, corrosion-resistant, wear-resistant, and easy to process. Of course, other materials, such as wood or plastic, can also be selected depending on the actual situation; this embodiment only uses aluminum as an example.

[0043] The rectangular frame is hollow inside to accommodate the core panel 4, serving to fix and protect it, ensuring its stable installation within the aluminum-framed glass door panel without loosening or shifting. The core panel 4 can be a glass core panel, a wood core panel, or a plastic core panel. Glass core panels offer good light transmission, suitable for scenarios requiring natural light, such as interior partitions and shower doors; wood core panels have natural wood grain and a warm texture, suitable for users seeking a natural style; plastic core panels offer good waterproof and moisture-proof performance, suitable for humid environments such as bathrooms and kitchens. This embodiment uses a glass core panel as an example.

[0044] Combination Figures 6-10 As shown, the aforementioned frame receiving member 110 is used to provide a hollow structure and form a connection interface. The frame receiving member 110 has a hollow quadrilateral cross-section and is surrounded by a first receiving side plate 1101, a second receiving side plate 1102, a third receiving side plate 1103, and a fourth receiving side plate 1104. The first receiving side plate 1101 and the third receiving side plate 1103 are parallel, the second receiving side plate 1102 and the fourth receiving side plate 1104 are parallel, and the first receiving side plate 1101 and the second receiving side plate 1102 intersect. The hollow quadrilateral structure provides sufficient strength and stability while ensuring lightweight design, ensuring that the door panel will not deform or be damaged during use. It also facilitates the insertion of the frame corner bracket 3, and the hollow design reduces weight and provides a certain cushioning effect.

[0045] The aforementioned first C-shaped structure 112 is fixedly connected to the side of the third receiving side plate 1103 away from the first receiving side plate 1101, and the opening of the first C-shaped structure 112 faces away from the first receiving side plate 1101. This structure can be used to embed into the first decorative snap-fit ​​portion 2102 in the first inverted F-shaped part 210, serving a fixing or positioning function.

[0046] Combination Figure 9 and Figure 10 As shown, the aforementioned step member 113 provides a connection point and positioning function for the installation of the border decorative strip 2. The step member 113 is fixedly connected to the side of the second receiving side plate 1102 away from the first receiving side plate 1101, with the step surface facing the first U-shaped structure 112. The step member 113 can provide additional support or connection points for the first inverted F-shaped member 210, enhancing the stability of the structure.

[0047] Along the direction from the second border 12 to the fourth border 14, the length of the step member 113 in the first border 11 and the third border 13 is greater than the length of the first C-shaped structure 112 in the first border 11 and the third border 13; along the direction from the first border 11 to the third border 13, the length of the step member 113 in the second border 12 and the fourth border 14 is greater than the length of the first C-shaped structure 112 in the second border 12 and the fourth border 14, which facilitates the subsequent implementation of inclined connections at the connection points of the first border 11 and the second border 12, the second border 12 and the third border 13, the third border 14 and the fourth border 14, and the fourth border 14 and the first border 11, such as 45-degree inclined connections.

[0048] Combination Figure 8 , Figure 9 and Figure 10 As shown, the frame connector 111 includes an L-shaped member 1110 and an inverted T-shaped member 1111. The L-shaped member 1110 is connected to the side of the first receiving side plate 1101 away from the second receiving side plate 1102, and is used to fix the core plate 4. The inverted T-shaped member 1111 is connected to the side of the fourth receiving side plate 1104 away from the second receiving side plate 1102, and forms a second C-shaped structure with a portion of the fourth receiving side plate 1104. The opening of the second C-shaped structure faces away from the side of the L-shaped member 1110, and the second C-shaped structure is used to embed the second decorative snap-fit ​​portion 2111 in the second inverted F-shaped member 211. The second C-shaped structure can achieve a hidden connection, such as by using the second inverted F-shaped member 211 to cover the second C-shaped structure, avoiding the exposure of the inverted T-shaped member 1111 and the L-shaped member 1110, thereby improving aesthetics.

[0049] The L-shaped member 1110 connects to the side of the first receiving side plate 1101 away from the second receiving side plate 1102, providing stable support for the first frame 11, second frame 12, third frame 13, and fourth frame 14 along their length, preventing lateral deformation of the first frame 11, second frame 12, third frame 13, and fourth frame 14 during use. The inverted T-shaped member 1111 connects to the side of the fourth receiving side plate 1104 away from the second receiving side plate 1102. The design of the inverted T-shaped member 1111 creates a second C-shaped structure between it and the fourth receiving side plate 1104, with the opening of the second C-shaped structure facing away from the side of the L-shaped member 1110. This design can be used to embed the second decorative snap-fit ​​portion 2111 in the second inverted F-shaped member 211, serving a fixing and positioning function.

[0050] Combination Figure 5 and Figure 10As shown, the number of frame brackets 3 can be four. These four brackets 3 are respectively inserted into the connection points between the frame receiving parts 110 of the first frame 11 and the frame receiving parts 110 of the second frame 12, the frame receiving parts 110 of the second frame 12 and the frame receiving parts 110 of the third frame 13, the frame receiving parts 110 of the third frame 13 and the frame receiving parts 110 of the fourth frame 14, and the frame receiving parts 110 of the fourth frame 14 and the frame receiving parts 110 of the first frame 11. The frame brackets 3 are used to connect adjacent frame receiving parts 110, ensuring the door frame 1 is sturdy and reliable. The design of the frame brackets 3 allows the connectors to be hidden inside the door frame 1, avoiding exposed bolts or connection marks, and improving the overall aesthetics of the aluminum frame glass door panel.

[0051] The aforementioned third receiving side plate 1103 has connecting holes 11031 on both sides along its length. These connecting holes 11031 penetrate the third receiving side plate 1103 in the direction pointing towards the first receiving side plate 1101, and their orthographic projections do not overlap with the orthographic projections of the first U-shaped structure 112. The position of these connecting holes 11031 is independent and does not overlap with the area of ​​the first U-shaped structure 112, thus avoiding structural conflicts.

[0052] Combination Figure 3 and Figure 5 As shown, the connection hole 11031 and the frame bracket 3 are fitted together such that the orthographic projection of the connection hole 11031 completely overlaps with the frame bracket 3, and the position of the connection hole 11031 precisely matches the position of the frame bracket 3. Fasteners 5 (e.g., bolts) can be connected to the frame bracket 3 through the connection hole 11031, thereby firmly fixing the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 together.

[0053] The combination of the frame corner brackets 3 and fasteners 5 strengthens the connection between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. The frame corner brackets 3 provide additional support points, while the fasteners 5 ensure that the frames do not loosen, thus enhancing the structural stability of the entire aluminum-framed glass door panel. The placement of the connecting holes 11031 allows the fasteners 5 to be concealed within the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14, without being exposed. This concealed design is not only aesthetically pleasing but also avoids the risk of scratches or damage from exposed nail holes or bolt heads. The precise overlap between the connecting holes 11031 and the frame corner brackets 3 ensures accuracy and reliability during installation. This design reduces installation errors, improves production efficiency, and also guarantees the overall quality of the aluminum-framed glass door panel. This connection method allows for adjustment of the angle and position between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14, enabling the aluminum-framed glass door panel to be fine-tuned according to different installation requirements. Meanwhile, the hollow quadrilateral design also facilitates the installation of glass or other materials. By concealing the fasteners 5, the entire aluminum frame glass door panel surface is more concise and smooth, without obvious splicing marks or exposed connection parts 310.

[0054] It should be noted that the first receiving side panel 1101, the second receiving side panel 1102, the third receiving side panel 1103, the fourth receiving side panel 1104, the first U-shaped structure 112, the stepped component 113, the L-shaped component 1110, and the inverted T-shaped component 1111 are all integrally connected. This integral connection eliminates gaps between the components, forming a unified structure that significantly enhances the overall stability of the frame. It also effectively prevents loosening or separation between components, ensuring that the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 remain sturdy during use. In other words, the integral connection method not only enhances structural stability and improves connection strength but also simplifies the installation process, improves overall aesthetics, reduces maintenance costs, and increases production efficiency.

[0055] Continue to refer to Figure 4As shown, the decorative border strip 2 provides an aesthetically pleasing appearance, covering the surface of the border housing 110 and making the aluminum frame glass door panel look cleaner and smoother. The decorative border strip 2 is formed by sequentially connecting a first decorative profile 21, a second decorative profile 22, a third decorative profile 23, and a fourth decorative profile 24 to form a rectangular frame. Each decorative profile fits onto its corresponding border; that is, the first decorative profile 21 fits onto the first border 11, the second decorative profile 22 fits onto the second border 12, the third decorative profile 23 fits onto the third border 13, and the fourth decorative profile 24 fits onto the fourth border 14. The first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24 protect the first border 11, the second border 12, the third border 13, and the fourth border 14 from external scratches and damage, extending the service life of the door frame 1.

[0056] The first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24 are composed of the first inverted F-shaped part 210 and the second inverted F-shaped part 211. These two parts are integrally connected, which reduces the number of parts and lowers the assembly difficulty. The materials of the first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24 are the same as the materials of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. When the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are made of aluminum, the materials of the first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24 are also made of aluminum.

[0057] Combination Figure 4 and Figure 5 As shown, in the first decorative profile 21, the second inverted F-shaped part 211 is located on the side of its first inverted F-shaped part 210 that is close to the third decorative profile 23; in the second decorative profile 22, the second inverted F-shaped part 211 is located on the side of its first inverted F-shaped part 210 that is close to the fourth decorative profile 24; in the third decorative profile 23, the second inverted F-shaped part 211 is located on the side of its first inverted F-shaped part 210 that is close to the first decorative profile 21; and in the fourth decorative profile 24, the second inverted F-shaped part 211 is located on the side of its first inverted F-shaped part 210 that is close to the first decorative profile 21. The first inverted F-shaped component 210 in the first decorative profile 21, the first inverted F-shaped component 210 in the second decorative profile 22, the first inverted F-shaped component 210 in the third decorative profile 23, and the first inverted F-shaped component 210 in the fourth decorative profile 24 form an outer decorative rectangular frame; the second inverted F-shaped component 211 in the first decorative profile 21, the second inverted F-shaped component 211 in the second decorative profile 22, the second inverted F-shaped component 211 in the third decorative profile 23, and the second inverted F-shaped component 211 in the fourth decorative profile 24 form an inner decorative rectangular frame.

[0058] The first inverted F-shaped member 210 is located on the side of the second inverted F-shaped member 211 near the step member 113. It includes a first inverted L-shaped portion 2101 and a first decorative snap-fit ​​portion 2102 connected thereto. The side of the first inverted L-shaped portion 2101 away from the second inverted F-shaped member 211 contacts the step member 113, serving a supporting and positioning function. The first decorative snap-fit ​​portion 2102 snaps into the opening of the first C-shaped structure 112, thereby fixing the decorative profile to the frame receiving member 110 through this snap-fit ​​method.

[0059] The second inverted F-shaped component 211 includes a second inverted L-shaped portion 2110 and a second decorative snap-fit ​​portion 2111 connected to the second inverted L-shaped portion 2110. The second decorative snap-fit ​​portion 2111 snaps into the opening of the second C-shaped structure, further fixing the first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24, ensuring that they are tightly joined with the frame receiving component 110.

[0060] Through the design of the first inverted F-shaped part 210 and the second inverted F-shaped part 211, the fastener 5 is completely hidden between the frame decorative strip 2 and the door frame 1, eliminating exposed fasteners 5 (such as bolts, specifically bolt heads) and connecting holes 11031 (such as nail holes), making the entire aluminum frame glass door panel surface cleaner and smoother. The frame decorative strip 2 completely covers the door frame 1, forming an integral rectangular frame, which is more visually unified and enhances the overall aesthetics of the product. The first decorative snap-fit ​​part 2102 snaps into the opening of the first C-shaped structure 112, and the second decorative snap-fit ​​part 2111 snaps into the opening of the second C-shaped structure. This snap-fit ​​method not only fixes the decorative profile but also enhances the connection strength between the door frame 1 and the frame decorative strip 2, preventing the frame decorative strip 2 from loosening or falling off during use.

[0061] Because of the snap-fit ​​design, the first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and the fourth decorative profile 24 can be easily disassembled, facilitating maintenance or replacement of the door frame 1 or the core panel 4. If the first decorative profile 21, the second decorative profile 22, the third decorative profile 23, and / or the fourth decorative profile 24 are damaged, they can be replaced individually without replacing the entire door frame 1 or the edge decorative strip 2, thus reducing maintenance costs.

[0062] It should be noted that: along the direction from the second border 12 to the fourth border 14, the length of the first inverted F-shaped piece 210 in the second decorative profile 22 and the fourth decorative profile 24 is greater than the length of the second inverted F-shaped piece 211 in the second decorative profile 22 and the fourth decorative profile 24; along the direction from the first border 11 to the third border 13, the length of the first inverted F-shaped piece 210 in the first decorative profile 21 and the third decorative profile 23 is greater than the length of the second inverted F-shaped piece 211 in the first decorative profile 21 and the third decorative profile 23. This facilitates the subsequent implementation of beveled connections, such as 45-degree beveled connections, at the connection points of the first decorative profile 21 and the second decorative profile 22, the second decorative profile 22 and the third decorative profile 23, the third decorative profile 23 and the fourth decorative profile 24, and the fourth decorative profile 24 and the first decorative profile 21.

[0063] Compared with the prior art, the aluminum frame glass door panel with concealed nail holes provided in this embodiment achieves at least the following beneficial effects:

[0064] Firstly, through the design of the first C-shaped structure 112, the frame receiving member 110, the frame connecting member 111 (such as the L-shaped member 1110 and the inverted T-shaped member 1111), and the frame decorative strip 2, the inverted T-shaped member 1111, the connecting hole 11031, and the fastener 5 in the first C-shaped structure 112 and the frame connecting member 111 can be directly hidden between the first receiving side plate 1101 and the corresponding frame decorative strip 2 in the frame receiving member 110. This avoids exposed connecting holes 11031, fasteners 5 (bolts), or other connection marks, making the surface of the aluminum frame glass door panel cleaner and smoother. This not only matches the metallic texture of the high-precision anodized surface, but also prevents dust accumulation or moisture intrusion at the weak point of the connection hole 11031; the frame decorative strip 2 covers the surface of the frame receiving part 110 and the inverted T-shaped part 1111, which can prevent the frame receiving part 110 and the inverted T-shaped part 1111 from being scratched and damaged by the outside world, and extend the service life of the door frame 1; the frame decorative strip 2 completely covers the frame receiving part 110 and the inverted T-shaped part 1111 of the door frame 1, forming an integral rectangular frame, which is more visually unified and improves the overall aesthetics of the product;

[0065] Secondly, the first inverted F-shaped part 210 and the second inverted F-shaped part 211 make the structure of the first decorative profile 21, the second decorative profile 22, the third decorative profile 23 and the fourth decorative profile 24 simple, without any superfluous decorations or protruding parts; the frame decorative strip 2 is firmly fixed to the frame receiving part 110 and the inverted T-shaped part 1111 through the snap-fit ​​design of the first inverted F-shaped part 210 and the second inverted F-shaped part 211, which further enhances the integrity of the door frame 1.

[0066] Third, through the cooperation of the frame corner brackets 3 and fasteners 5, a firm connection is achieved between the frame receiving parts 110, enhancing the structural strength of the entire door frame 1. The hollow quadrilateral structure of the frame receiving part 110 reduces weight while providing sufficient support strength, ensuring that the aluminum frame glass door panel will not deform or be damaged during use.

[0067] Fourth, the frame decorative strip 2 is fixed to the frame receiving member 110 and the inverted T-shaped member 1111 by a snap-fit ​​method, eliminating the need for bolts or other fasteners 5, greatly simplifying the installation process and reducing installation time and cost; the second C-shaped structure between the first C-shaped structure 112, the inverted T-shaped member 1111 and the frame receiving member 110 provides a precise positioning function, ensuring that different decorative profiles can be installed quickly and accurately; the snap-fit ​​design of the first decorative profile 21, the second decorative profile 22, the third decorative profile 23 and the fourth decorative profile 24 makes them easy to disassemble, facilitating the maintenance or replacement of the frame decorative strip 2 and the door frame 1. If the first decorative profile 21, the second decorative profile 22, the third decorative profile 23 and / or the fourth decorative profile 24 are damaged, they can also be replaced individually without replacing the entire frame decorative strip 2, reducing maintenance costs.

[0068] In one optional embodiment, the connecting hole 11031 includes a circular first connecting hole 11031a and a circular second connecting hole 11031b; the third receiving side plate 1103 in the first frame 11 and the third frame 13 respectively has a first connecting hole 11031a on the side near the second frame 12 and the side near the fourth frame 14, and the number of the first connecting hole 11031a is one; the third receiving side plate 1103 in the second frame 12 and the fourth frame 14 respectively has a second connecting hole 11031b on the side near the first frame 11 and the side near the third frame 13, and the number of the second connecting holes 11031b is two.

[0069] Specifically, in combination Figure 3 and Figure 5 As shown, a first connecting hole 11031a is provided on each side of the third receiving side plate 1103 along its length in the first frame 11 and the third frame 13. The first connecting hole 11031a is circular in shape and is used to install fasteners 5 to ensure that the connection between the first frame 11 and the frame bracket 3, and between the third frame 13 and the frame bracket 3 is firm and reliable, thereby improving the stability of the connection between the first frame 11 and the second frame 12, between the first frame 11 and the fourth frame 14, between the third frame 13 and the second frame 12, and between the third frame 13 and the fourth frame 14.

[0070] In the second frame 12 and the fourth frame 14, two second connecting holes 11031b are respectively opened on both sides of the third receiving side plate 1103 along its length direction. The second connecting holes 11031b are circular in shape. By increasing the number of connection points, the connection strength between the second frame 12 and the frame bracket 3 and between the fourth frame 14 and the frame bracket 3 is further enhanced, preventing the door frame 1 from loosening or deforming during use.

[0071] Using the above scheme, each of the first frame 11 and the third frame 13 has one first connecting hole 11031a along its length, and each of the second frame 12 and the fourth frame 14 has two second connecting holes 11031b along its length. This symmetrical layout of the connecting holes 11031 makes the structure of the entire aluminum frame glass door panel more balanced, avoiding structural deformation caused by uneven distribution of connection points. The reasonable distribution of the connecting holes 11031 also ensures that the aluminum frame glass door panel is subjected to uniform stress during use, extending its service life. The design of the connecting holes 11031 allows the fasteners 5 (bolts) to be hidden inside the first frame 11, second frame 12, third frame 13, and fourth frame 14, avoiding exposed nail holes or bolt heads and maintaining the cleanliness and aesthetics of the aluminum frame glass door panel surface. The clear location and number of the connecting holes 11031 make the installation process simpler and faster. Installers can quickly and accurately install the fasteners 5 according to the pre-designed locations of the connecting holes 11031. The pre-designed connection holes 11031 can also reduce errors during installation and improve installation efficiency and quality.

[0072] In one alternative embodiment, combined with Figure 5 , Figure 6 and Figure 11 As shown, Figure 11 This is a schematic diagram of the structure of the frame corner bracket provided by this utility model; the frame corner bracket 3 includes a long plug-in 31 and a short plug-in 32 integrally connected to the long plug-in 31. The long plug-in 31 and the short plug-in 32 form an L-shaped structure. The long plug-in 31 is inserted into the end of the second frame 12 and the end of the fourth frame 14 near the first frame 11 and the end of the third frame 13, respectively. The short plug-in 32 is inserted into the end of the first frame 11 and the end of the third frame 13 near the second frame 12 and the end of the fourth frame 14, respectively.

[0073] Specifically, the number of frame corner brackets 3 can be four. Each frame corner bracket 3 includes a long connector 31 and a short connector 32. The long connector 31 and the short connector 32 are integrated to form a whole. The long connector 31 and the short connector 32 form an L-shaped structure. The L-shaped structure allows the frame corner bracket 3 to connect two adjacent frames at the same time, such as the first frame 11 and the second frame 12, the second frame 12 and the third frame 13, the third frame 13 and the fourth frame 14, and the fourth frame 14 and the first frame 11.

[0074] Two long connectors 31 are respectively inserted into the two ends of the second frame 12 along its length direction, two other long connectors 31 are respectively inserted into the two ends of the fourth frame 14 along its length direction, two short connectors 32 are respectively inserted into the two ends of the first frame 11 along its length direction, and two other short connectors 32 are respectively inserted into the two ends of the third frame 13 along its length direction.

[0075] Using the above scheme, the L-shaped structure formed by the long connector 31 and the short connector 32 can simultaneously connect two adjacent frames, ensuring a firm and reliable connection between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14. This structural design effectively prevents the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 from loosening or deforming during use. Through the combination of the long connector 31 and the short connector 32, both ends of each of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 can be connected to other frames at multiple points, further enhancing the structural stability of the entire door panel. The integrated connection of the long connector 31 and the short connector 32 reduces the number of parts that need to be handled during installation, simplifying the installation steps. Installers can quickly and accurately connect the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 to the frame bracket 3, improving installation efficiency. The second frame 12 and the fourth frame 14 use long connectors 31, while the first frame 11 and the third frame 13 use short connectors 32. This symmetrical layout makes the structure of the entire aluminum frame glass door panel more balanced.

[0076] In one optional embodiment, the long connector 31 is provided with a connecting portion 310 on the side away from the short connector 32 and the short connector 32 is provided with a connecting portion 310 on the side away from the long connector 31. The connecting portion 310 of the long connector 31 is provided with a third connecting hole 3101 corresponding to the second connecting hole 11031b, and the connecting portion 310 of the short connector 32 is provided with a fourth connecting hole 3102 corresponding to the first connecting hole 11031a.

[0077] Fastener 5 includes a first fastener 51 and a second fastener. The first fastener 51 is connected to the third receiving side plate 1103 in the second frame 12 and the fourth frame 14 and the connecting part 310 in the long plug-in 31 through the second connecting hole 11031b and the third connecting hole 3101. The second fastener is connected to the third receiving side plate 1103 in the first frame 11 and the third frame 13 and the connecting part 310 in the short plug-in 32 through the first connecting hole 11031a and the fourth connecting hole 3102.

[0078] Specifically, in combination Figure 5 and Figure 11 As shown, the connecting portion 310 of the long connector 31, the connection between the long connector 31 and the short connector 32, and the connecting portion 310 of the short connector 32 form a triangular structure. This triangular structure not only evenly distributes external forces to the three vertices, effectively resisting deformation and displacement, but also provides multiple support points, further enhancing the stability of the connection. This multi-point support design can effectively disperse stress, reduce excessive local stress, and extend service life. A third connecting hole 3101 is provided in the connecting portion 310 of the long connector 31, which corresponds to and communicates with the second connecting hole 11031b in the second frame 12 and the fourth frame 14; a fourth connecting hole 3102 is provided in the connecting portion 310 of the short connector 32, which corresponds to and communicates with the first connecting hole 11031a in the first frame 11 and the third frame 13.

[0079] The first fastener 51 connects the second frame 12 and the fourth frame 14 to the long plug-in connector 31 through the second connecting hole 11031b (the second connecting hole 11031b is opened in the third receiving side plate 1103 of the second frame 12 and the fourth frame 14) and the third connecting hole 3101 (the third connecting hole 3101 is opened in the connecting part 310 of the long plug-in connector 31).

[0080] The second fastener connects the first frame 11 and the third frame 13 to the short connector 32 via the first connecting hole 11031a (the first connecting hole 11031a is opened in the third receiving side plate 1103 of the first frame 11 and the third frame 13) and the fourth connecting hole 3102 (the fourth connecting hole 3102 is opened in the connecting part 310 of the short connector 32).

[0081] Using the above scheme, the second frame 12 and the fourth frame 14 are connected to the long connector 31 via the first fastener 51 and the second fastener, respectively, and the first frame 11 and the third frame 13 are connected to the short connector 32. This multi-point connection method ensures a more secure connection between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 and the frame corner bracket 3, effectively preventing loosening or detachment. The corresponding design of the connecting holes 11031 (the second connecting hole 11031b and the third connecting hole 3101, and the first connecting hole 11031a and the fourth connecting hole 3102) ensures that the first fastener 51 and the second fastener can be accurately installed, improving the reliability and stability of the connection. The first fastener 51 and the second fastener are installed inside the door frame 1 through the connecting holes 11031, avoiding exposed bolts (such as bolt heads) and maintaining the cleanliness and aesthetics of the aluminum frame glass door panel surface.

[0082] The first frame 11 and the third frame 13 use short connectors 32, while the second frame 12 and the fourth frame 14 use long connectors 31. This symmetrical connection method makes the entire door panel structure more balanced. By rationally distributing the connection points, it is ensured that the aluminum frame glass door panel is subjected to uniform stress during use, thus extending the service life of the aluminum frame glass door panel.

[0083] In one alternative embodiment, combined with Figure 5 , Figure 9 , Figure 12 and Figure 13 As shown, Figure 12 This is an assembly diagram of the fourth frame, part of the first frame, and the frame corner bracket provided by this utility model; Figure 13 This is a rear view of an aluminum frame glass door panel with concealed nail holes provided by this utility model; hinge openings are respectively provided at the end of the first receiving side plate 1101 in the fourth frame 14 near the first frame 11, at the end of the first receiving side plate 1101 in the first frame 11 near the fourth frame 14 and at the end of the first receiving side plate 1101 in the second frame 12 near the first frame 11; the hinge opening of the first receiving side plate 1101 in the fourth frame 14 is connected to the hinge opening of the first receiving side plate 1101 in the first frame 11 near the fourth frame 14 and forms a first L-shaped hinge opening 11011; the hinge opening of the first receiving side plate 1101 in the second frame 12 is connected to the hinge opening of the first receiving side plate 1101 in the first frame 11 near the second frame 12 and forms a second L-shaped hinge opening 11012, with the apex of the first L-shaped hinge opening 11011 facing the apex of the second L-shaped hinge opening 11012.

[0084] Specifically, the first receiving side plate 1101 in the fourth frame 14 has a rectangular hinge opening at one end near the first frame 11. The hinge opening of the first receiving side plate 1101 in the fourth frame 14 is recessed towards the third frame 13. The first receiving side plate 1101 in the first frame 11 has rectangular hinge openings at both ends along its length. The hinge opening of the first receiving side plate 1101 in the first frame 11 near the fourth frame 14 is recessed towards the second frame 12. The hinge opening of the first receiving side plate 1101 in the first frame 11 near the second frame 12 is recessed towards the fourth frame 14. The first receiving side plate 1101 in the second frame 12 has a rectangular hinge opening at one end near the first frame 11. The hinge opening of the first receiving side plate 1101 in the second frame 12 is recessed towards the third frame 13.

[0085] A first L-shaped hinge opening 11011 is formed between the hinge opening of the first receiving side panel 1101 in the fourth frame 14 and the hinge opening of the first receiving side panel 1101 in the first frame 11. A second L-shaped hinge opening 11012 is formed between the hinge opening of the first receiving side panel 1101 in the first frame 11 and the hinge opening of the first receiving side panel 1101 in the second frame 12. Through the first L-shaped hinge opening 11011 and the second L-shaped hinge opening 11012, the connection between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 becomes more intuitive and simple. Installers can quickly align different frames according to the position of the hinge openings, reducing installation time and errors. At the same time, installers can quickly align the cabinet body of the wine storage cabinet according to the position of the hinge openings and fix the door frame 1 to the cabinet body of the wine storage cabinet using the frame bracket 3. Since the connection position of the hinge openings has been preset, no additional measuring or marking tools are required during the installation process, further simplifying the installation steps.

[0086] In one alternative embodiment, along the direction from the third receiving side plate 1103 to the first receiving side plate 1101, the orthographic projection of the inverted T-shaped member 1111 is located within the orthographic projection of the L-shaped member 1110, and the surface of the second inverted F-shaped member 211 away from the first inverted F-shaped member 210 is flush with the surface of the L-shaped member 1110 away from the first receiving side plate 1101.

[0087] Specifically, in combination Figure 9 and Figure 10As shown, along the direction from the first receiving side plate 1101 to the third receiving side plate 1103, the height of the inverted T-shaped part 1111 is lower than the height of the L-shaped part 1110. When the second decorative snap-fit ​​part 2111 snaps into the opening of the second U-shaped structure, after the inner wall of the second inverted F-shaped part 211 is tightly fitted with the side of the inverted T-shaped part 1111 away from the fourth receiving side plate 1104, it can also be flush with the surface of the L-shaped part 1110 away from the first receiving side plate 1101. The surfaces of the second inverted F-shaped part 211 and the L-shaped part 1110 appear to be continuous without obvious steps.

[0088] In an optional embodiment, the contact surfaces between the frame accommodating member 110 in the first frame 11 and the frame accommodating member 110 in the second frame 12, the contact surfaces between the frame accommodating member 110 in the second frame 12 and the frame accommodating member 110 in the third frame 13, the contact surfaces between the frame accommodating member 110 in the third frame 13 and the frame accommodating member 110 in the fourth frame 14, and the contact surfaces between the frame accommodating member 110 in the fourth frame 14 and the frame accommodating member 110 in the first frame 11 are all first inclined surfaces 114, and the inclination angle of the first inclined surface 114 is 45°.

[0089] The contact surfaces between the first decorative profile 21 and the second decorative profile 22, the contact surfaces between the second decorative profile 22 and the third decorative profile 23, the contact surfaces between the third decorative profile 23 and the fourth decorative profile 24, and the contact surfaces between the fourth decorative profile 24 and the first decorative profile 21 are all second inclined surfaces 212, with an inclination angle of 45°.

[0090] Specifically, in combination Figure 3 and Figure 5 As shown, the contact surface between the first frame 11 and the second frame 12 is the first inclined surface 114, and the inclination angle of the first inclined surface 114 is 45°; the contact surface between the second frame 12 and the third frame 13 is the first inclined surface 114, and the inclination angle of the first inclined surface 114 is 45°; the contact surface between the third frame 13 and the fourth frame 14 is the first inclined surface 114, and the inclination angle of the first inclined surface 114 is 45°; the contact surface between the fourth frame 14 and the first frame 11 is the first inclined surface 114, and the inclination angle of the first inclined surface 114 is 45°.

[0091] Combination Figure 4 and Figure 5As shown, the contact surface between the first decorative profile 21 and the second decorative profile 22 is the second inclined surface 212, and the inclination angle of the second inclined surface 212 is 45°. The contact surface between the second decorative profile 22 and the third decorative profile 23 is the second inclined surface 212, and the inclination angle of the second inclined surface 212 is 45°. The contact surface between the third decorative profile 23 and the fourth decorative profile 24 is the second inclined surface 212, and the inclination angle of the second inclined surface 212 is 45°. The contact surface between the fourth decorative profile 24 and the first decorative profile 21 is the second inclined surface 212, and the inclination angle of the second inclined surface 212 is 45°.

[0092] By adopting the above scheme, the 45° bevel design not only provides a better contact area and support effect, but also, compared with the flat contact, the bevel (such as the first bevel 114 and the second bevel 212) can better disperse stress and reduce the situation of excessive local stress, thereby enhancing the structural stability of the entire door frame 1. At the same time, the design of the first bevel 114 and the second bevel 212 makes the connection between the door frame 1 and the frame decorative strip 2 more symmetrical, further improving the balance of the entire aluminum frame glass door panel and ensuring that it will not deform due to uneven stress during use. In addition, the design of the first bevel 114 and the second bevel 212 makes the transition between the door frame 1 and the frame decorative strip 2 more natural, reduces obvious splicing marks, and makes the door panel surface smoother and cleaner.

[0093] In one alternative embodiment, an accommodating space is formed between the L-shaped member 1110, a portion of the fourth accommodating side plate 1104, and the inverted T-shaped member 1111;

[0094] The aluminum frame glass door panel also includes a core panel 4, which is embedded in a rectangular frame enclosed by the receiving space in the first frame 11, the receiving space in the second frame 12, the receiving space in the third frame 13, and the receiving space in the fourth frame 14.

[0095] Specifically, continue to refer to Figure 10 As shown, there is a certain accommodating space between the L-shaped member 1110, a portion of the fourth accommodating side plate 1104, and the inverted T-shaped member 1111, which can accommodate the core plate 4. This accommodating space is located inside the frame and is formed by the L-shaped member 1110, the fourth accommodating side plate 1104, and the inverted T-shaped member 1111.

[0096] The core panel 4 is an important component of the aluminum frame glass door panel, typically used to provide additional strength, heat insulation, or sound insulation. The core panel 4 is embedded within a rectangular frame formed by the receiving spaces in the first frame 11, second frame 12, third frame 13, and fourth frame 14. That is, the core panel 4 is installed inside the first frame 11, second frame 12, third frame 13, and fourth frame 14, forming a single unit with them.

[0097] The core panel 4 is embedded within the receiving spaces of the first frame 11, second frame 12, third frame 13, and fourth frame 14, providing additional support for the entire aluminum frame glass door panel and enhancing its overall structural stability. The presence of the core panel 4 makes the aluminum frame glass door panel more robust during use, enabling it to withstand greater external forces. The core panel 4 can also distribute stress, reducing deformation of the first frame 11, second frame 12, third frame 13, and fourth frame 14 under load, thus extending the service life of the aluminum frame glass door panel.

[0098] By embedding the core panel 4 into the first frame 11, second frame 12, third frame 13, and fourth frame 14, the heat insulation and sound insulation effects of the aluminum frame glass door panel can be effectively improved, enhancing its functionality. The embedding of the core panel 4 gives the aluminum frame glass door panel not only aesthetic appeal but also practical heat insulation and sound insulation functions, making it suitable for various applications such as interior partitions, cabinet doors, and wine storage cabinets.

[0099] As can be seen from the above embodiments, the aluminum frame glass door panel with concealed nail holes provided by this utility model achieves at least the following beneficial effects:

[0100] Firstly, through the design of the first C-shaped structure, frame housing, frame connectors (such as L-shaped and inverted T-shaped pieces), and frame decorative strips, the first C-shaped structure, frame connectors, connecting holes, and fasteners are hidden inside, avoiding exposed connecting holes (such as nail holes), fasteners (bolts), or other connection marks. This makes the surface of the aluminum frame glass door panel cleaner and smoother, not only matching the metallic texture of the high-precision anodized surface but also preventing dust accumulation or moisture intrusion at the weak points of the connecting holes. The frame decorative strip covers the surface of the frame housing and inverted T-shaped pieces, preventing them from being scratched and damaged by external factors, thus extending the service life of the door frame. The frame decorative strip completely covers the frame housing and inverted T-shaped pieces of the door frame, forming a unified rectangular frame that is more visually consistent and enhances the overall aesthetics of the product.

[0101] Secondly, the first and second inverted F-shaped parts make the structure of the first, second, third, and fourth decorative profiles simple, without any superfluous decorations or protruding parts; the frame decorative strip is firmly fixed to the frame receiving part and the inverted T-shaped part through the snap-fit ​​design of the first and second inverted F-shaped parts, further enhancing the integrity of the door frame.

[0102] Third, through the cooperation of frame corner brackets and fasteners, a firm connection is achieved between the frame retainers, enhancing the structural strength of the entire door frame. The hollow quadrilateral structure of the frame retainers reduces weight while providing sufficient support strength, ensuring that the aluminum frame glass door panel will not deform or be damaged during use.

[0103] Fourth, the frame trim is fixed to the frame housing and the inverted T-shaped piece by a snap-fit ​​method, eliminating the need for bolts or other fasteners, greatly simplifying the installation process and reducing installation time and costs. The second C-shaped structure between the first C-shaped structure, the inverted T-shaped piece, and the frame housing provides a precise positioning function, ensuring that different decorative profiles can be installed quickly and accurately. The snap-fit ​​design of the first, second, third, and fourth decorative profiles allows for easy disassembly, facilitating the maintenance or replacement of the frame trim and door frame. If the first, second, third, and / or fourth decorative profiles are damaged, they can be replaced individually without replacing the entire frame trim, reducing maintenance costs.

[0104] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
