Description

Technical Field

[0001] The present invention relates to the field of furniture technology, and more specifically, to an aluminum frame glass door panel with hidden nail holes. The patent name of the present invention can also be an aluminum frame glass door panel with hidden nail holes. Background Art

[0002] Compared with traditional wooden door panels, aluminum-framed glass door panels have significant advantages in performance and aesthetic value due to their unique material combination and process innovation. First, the aluminum alloy frame adopts high-strength profiles and multi-cavity structure design, and its bending resistance is 3-5 times higher than that of wooden frames. Combined with the zero expansion characteristics of tempered glass, it can effectively avoid the deformation and cracking problems of wooden door panels that are easily affected by temperature and humidity. It is especially suitable for high-humidity environments (such as kitchens and bathrooms); secondly, the anodizing or fluorocarbon spraying process gives the aluminum surface excellent wear and corrosion resistance, and its service life can be more than twice that of wooden door panels, and no regular painting and maintenance is required. In terms of visual presentation, the combination of transparent glass and narrow metal frames (as thin as 8mm) breaks through the sense of physical enclosure of wooden door panels, and creates a modern minimalist aesthetic through light refraction and space extension. At the same time, it supports customized surface treatments such as gradient glaze and intelligent atomization to achieve a deep integration of function and decoration. In addition, the environmental friendliness of the modular aluminum profile structure throughout its entire life cycle is also a prominent highlight. Aluminum alloy can be 100% recycled and reused, avoiding the formaldehyde release and resource consumption problems of wood panels, and is in line with the development trend of green homes.

[0003] While existing aluminum-framed glass door panels evolve in pursuit of minimalist aesthetics and structural strength, they still face the core pain point of exposed nail holes, which compromises overall aesthetics. Traditional installation methods rely on screws or angle brackets to mechanically secure the aluminum profile, resulting in visible nail holes or seams on the frame surface. This is particularly noticeable in ultra-narrow frame designs (≤15mm), where these holes lack effective concealment, making them even more obtrusive and detracting from the panel's "smooth" visual experience. While some solutions have attempted to cover these holes with glue injection or decorative frame strips, long-term use can lead to issues such as glue aging, discoloration, and cover plate peeling, and they struggle to match the metallic texture of the high-precision anodized surface. Furthermore, nail holes create weak points for dust accumulation and moisture intrusion, indirectly impacting sealing performance. The industry is exploring pre-buried nut structures, magnetic splicing processes, or nail-free adhesive bonding to eliminate exposed fasteners. However, due to limitations in aluminum profile machining precision, connection strength, and cost control, a universal solution has yet to be established. This technical bottleneck restricts the penetration rate of aluminum-framed glass door panels in the high-end customized home 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, refer to Figure 1 As shown, Figure 1Schematic diagram of the overall structure of a glass door in a Chinese patent document; the minimalist glass door includes a frame 100' and a glass core board 200', the glass core board 200' is fixed to the inner side of the frame 100', a circular hole is opened on the side of the glass core board 200' close to the door handle, and the circular hole is used for a handle assembly 300', and the handle assembly 300' includes a first split part and a second split part, the first split part is provided with an external thread and a slot, the second split part is provided with an internal thread, and the inner side of the second split part is also provided with an inner cavity groove for inserting a finger to open the door, and the first split part and the second split part are respectively inserted from both sides of the glass core board 200'. The door handle is assembled by threaded connection. After the assembly is completed, the slot hole and the inner cavity groove are connected to each other. When the door is to be opened, the finger can be inserted from the slot hole on one side of the first split part, and then the door is hooked out using the steps between the inner side of the inner wall groove and the slot. After the installation is completed, the first split part is located on the outer surface of the glass core board 200' and is almost flush with it, and the second split part is located on the inner surface of the glass core board 200' and is flush with the thickness of the frame 100'. The second split part is located inside the cabinet, so the handle assembly 300' can be hidden. The application does not hide the nail holes opened at each top corner, that is, the above technical problem is not solved. Summary of the Invention

[0005] In view of this, the present invention provides an aluminum frame glass door panel with hidden nail holes to solve the problem in the prior art that the nail holes become weak points for dust accumulation or water vapor intrusion, indirectly affecting the sealing performance.

[0008] The first frame, the second frame, the third frame, and the fourth frame each include a frame receiving member with a hollow quadrilateral cross-section and a frame connecting member. The frame receiving member includes first receiving side plates, second receiving side plates, third receiving side plates, and fourth receiving side plates that are sequentially connected and enclose a hollow quadrilateral body. The first receiving side plates are parallel to the third receiving side plates, the second receiving side plates are parallel to the fourth receiving side plates, the first receiving side plates intersect the second receiving side plates, a first C-shaped structure is provided on one side of the third receiving side plates away from the first receiving side plates, and the opening of the first C-shaped structure faces away from the first receiving side plates. A step member is connected to one side of the second receiving side plates away from the first receiving side plates, and the step surface of the step member faces the first C-shaped structure; in the direction from the second frame to the fourth frame, the length of the step members in the first frame and the third frame is greater than the length of the first C-shaped structures in the first frame and the third frame; in the direction from the first frame to the third frame, the length of the step members in the second frame and the fourth frame is greater than the length of the first C-shaped structures in the second frame and the fourth frame.

[0009] The frame connecting member includes an L-shaped member and an inverted T-shaped member. The L-shaped member is connected to one side of the first receiving side plates away from the second receiving side plates, the inverted T-shaped member is connected to one side of the fourth receiving side plates away from the second receiving side plates, and a second C-shaped structure is formed between the inverted T-shaped member and a part of the fourth receiving side plates, and the opening of the second C-shaped structure faces away from the L-shaped member.

[0010] At the connection between the hollow quadrilateral bodies of the first frame and the second frame, at the connection between the hollow quadrilateral bodies of the second frame and the third frame, at the connection between the hollow quadrilateral bodies of the third frame and the fourth frame, and at the connection between the hollow quadrilateral bodies of the fourth frame and the first frame, group frame corner codes are respectively inserted. On both sides of the third receiving side plates along their length directions, connection holes are respectively provided. In the direction from the third receiving side plates to the first receiving side plates, the connection holes penetrate through the third receiving side plates. The orthographic projection of the connection holes does not overlap with the orthographic projection of the first C-shaped structures at all, and the orthographic projection of the connection holes completely overlaps with the orthographic projection of the group frame corner codes. Fasteners are connected to the group frame corner codes through the connection holes.

[0011] The border decorative strip includes a first decorative profile, a second decorative profile, a third decorative profile, and a fourth decorative profile that are sequentially connected and enclose 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. The first decorative profile, the second decorative profile, the third decorative profile, and the fourth decorative profile each include a first inverted F-shaped member and a second inverted F-shaped member integrally connected to the first inverted F-shaped member. The first inverted F-shaped member is located on the side of the second inverted F-shaped member close to the step member. The first inverted F-shaped member includes a first inverted L portion and a first decorative clamping portion connected to the first inverted L portion. The side of the first inverted L portion away from the second inverted F-shaped member contacts the step member.

[0012] Compared with the prior art, the hidden nail hole aluminum frame glass door panel provided by the present invention at least achieves the following beneficial effects:

[0013] First, through the design of the first C-shaped structure, the frame accommodating member, the frame connecting members (such as L-shaped members and inverted T-shaped members), and the frame decorative strip, the first C-shaped structure, the frame connecting members, the connecting holes, and the fasteners are hidden inside, avoiding exposed connecting holes (such as nail holes), fasteners (bolts), or other connecting traces, making the surface of the aluminum frame glass door panel cleaner and smoother. That is, it can not only match the metallic texture of the high-precision anodic oxidation surface but also avoid the weak points of dust accumulation or water vapor intrusion at the connecting holes, thereby improving its sealing performance; the frame decorative strip covers the surfaces of the frame accommodating member and the inverted T-shaped member, preventing the frame accommodating member and the inverted T-shaped member from being scratched and damaged by the outside world, and extending the service life of the door leaf frame; the frame decorative strip completely covers the frame accommodating member and the inverted T-shaped member of the door leaf frame, forming an integral rectangular frame, which is more visually unified and improves the overall aesthetics of the product. Second, through the first inverted F-shaped member and the second inverted F-shaped member, the structures of the first decorative profile, the second decorative profile, the third decorative profile, and the fourth decorative profile are simple, without redundant decorations or protruding parts; the frame decorative strip is firmly fixed on the frame accommodating member and the inverted T-shaped member through the snap connection design of the first inverted F-shaped member and the second inverted F-shaped member, further enhancing the integrity of the door leaf frame. Third, through the cooperation of the frame corner connector and the fasteners, a firm connection is achieved between the frame accommodating members, enhancing the structural strength of the entire door leaf frame. The hollow quadrilateral structure of the frame accommodating member provides sufficient support strength while reducing weight, ensuring that the aluminum frame glass door panel will not deform or be damaged during use. Fourth, the frame decorative strip is fixed on the frame accommodating member and the inverted T-shaped member by snap connection, without using bolts or other fasteners, greatly simplifying the installation process, reducing the installation time and cost; the second C-shaped structure between the first C-shaped structure, the inverted T-shaped member, and the frame accommodating member provides an accurate positioning function, ensuring that different decorative profiles can be quickly and accurately installed in place; the snap connection design of the first decorative profile, the second decorative profile, the third decorative profile, and the fourth decorative profile makes them easy to disassemble, facilitating the maintenance or replacement of the frame decorative strip and the door leaf frame. If the first decorative profile, the second decorative profile, the third decorative profile, and / or the fourth decorative profile is damaged, it can also be replaced individually without replacing the entire frame decorative strip, reducing the maintenance cost.

[0014] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned technical effects.

[0039] At the connection between the hollow tetrahedron of the first frame 11 and the hollow tetrahedron of the second frame 12, at the connection between the hollow tetrahedron of the second frame 12 and the hollow tetrahedron of the third frame 13, at the connection between the hollow tetrahedron of the third frame 13 and the hollow tetrahedron of the fourth frame 14, and at the connection between the hollow tetrahedron of the fourth frame 14 and the hollow tetrahedron of the first frame 11, group frame corner codes 3 are respectively inserted. Two connection holes 11031 are respectively opened on both sides of the third accommodating side plate 1103 along its length direction. Along the direction from the third accommodating side plate 1103 to the first accommodating side plate 1101, the connection holes 11031 penetrate through the third accommodating side plate 1103. The orthographic projection of the connection holes 11031 does not overlap with the orthographic projection of the first C-shaped structure 112 at all, and the orthographic projection of the connection holes 11031 completely overlaps with the orthographic projection of the group frame corner code 3. The fastener 5 is connected to the group frame corner code 3 through the connection holes 11031;

[0040] The border decorative strip 2 includes a first decorative profile 21, a second decorative profile 22, a third decorative profile 23, and a fourth decorative profile 24 that are sequentially connected and enclose a rectangular frame.

The second decorative clamping portion 2111 is clamped into the opening of the second C-shaped structure.

[0041] Specifically, the patent name of the present invention can also be an aluminum frame glass door panel. Combining Figure 2 , Figure 3 and Figure 5 As shown, the above door leaf frame 1 is formed by sequentially connecting a first border 11, a second border 12, a third border 13, and a fourth border 14, enclosing a rectangular frame. The first border 11 is parallel to the third border 13, the second border 12 is parallel to the fourth border 14 and axially symmetrically arranged, and the first border 11 is perpendicular to the second border 12. The above design constitutes the basic structure of the aluminum frame glass door panel, providing support and shape basis for the entire aluminum frame glass door panel.

[0042] Optionally, the materials of the first border 11, the second border 12, the third border 13, and the fourth border 14 can be aluminum. Aluminum has characteristics such as light weight, high strength, corrosion resistance, wear resistance, and easy processing. Of course, according to the actual situation, other materials can also be selected, such as wood or plastic. This embodiment only takes aluminum as an example for illustration.

[0043] The interior of the rectangular frame is hollow, which can accommodate the core panel 4, serving to fix and protect the core panel 4, ensuring that the core panel 4 is stably installed in the aluminum-framed glass door panel without loosening or shifting. The core panel 4 can be a glass core panel, a wooden core panel, or a plastic core panel. The glass core panel has good light transmittance and is suitable for scenes requiring lighting, such as indoor partitions and shower doors. The wooden core panel has a natural wood grain and warm texture, which is suitable for users who pursue a natural style. The plastic core panel has good waterproof and moisture-proof properties and is suitable for humid environments, such as bathrooms and kitchens. In this embodiment, the glass core panel is used as an example.

[0044] Combine Figures 6-10 As shown, the frame container 110 is used to provide a hollow structure and form a connection interface. The cross-section of the frame container 110 is a hollow quadrilateral, surrounded by a first accommodating side panel 1101, a second accommodating side panel 1102, a third accommodating side panel 1103, and a fourth accommodating side panel 1104. The first accommodating side panel 1101 is parallel to the third accommodating side panel 1103, the second accommodating side panel 1102 is parallel to the fourth accommodating side panel 1104, and the first accommodating side panel 1101 intersects with the second accommodating side panel 1102. The hollow quadrilateral structure provides sufficient strength and stability while ensuring lightweight, ensuring that the door panel will not deform or be damaged during use. It also facilitates the insertion of the frame assembly angle bracket 3. At the same time, the hollow design can reduce weight and provide a certain cushioning effect.

[0045] The first U-shaped structure 112 is fixedly connected to the side of the third receiving side panel 1103 away from the first receiving side panel 1101, with the opening of the first U-shaped structure 112 facing away from the first receiving side panel 1101. This structure can be used to embed the first decorative clip 2102 in the first inverted F-shaped member 210 to achieve a fixing or positioning function.

[0046] Combine Figure 9 and Figure 10 As shown, the 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 panel 1102 away from the first receiving side panel 1101, with the step surface facing the first F-shaped structure 112. The step member 113 can provide an additional support or connection point for the first inverted F-shaped member 210, thereby enhancing the stability of the structure.

[0047] In the direction from the second side frame 12 towards the fourth side frame 14, the length of the stepped member 113 in the first side frame 11 and the third side frame 13 is greater than the length of the first C-shaped structure 112 in the first side frame 11 and the third side frame 13; in the direction from the first side frame 11 towards the third side frame 13, the length of the stepped member 113 in the second side frame 12 and the fourth side frame 14 is greater than the length of the first C-shaped structure 112 in the second side frame 12 and the fourth side frame 14, which facilitates the subsequent bevel connection at the joints between the first side frame 11 and the second side frame 12, the second side frame 12 and the third side frame 13, the third side frame 14 and the fourth side frame 14, and the fourth side frame 14 and the first side frame 11, such as a 45-degree bevel connection.

[0048] Combined 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 for fixing 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 a second C-shaped structure is formed between it and a part of the fourth receiving side plate 1104. The opening of the second C-shaped structure faces away from the L-shaped member 1110 side, and the second C-shaped structure is used to embed the second decorative clamping portion 2111 of the second inverted F-shaped member 211. Through the second C-shaped structure, a hidden connection can be achieved. For example, by covering the second C-shaped structure with the second inverted F-shaped member 211, the inverted T-shaped member 1111 and the L-shaped member 1110 can be avoided from being exposed to improve the aesthetics.

[0049] 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, which can provide stable support for the first side frame 11, the second side frame 12, the third side frame 13, and the fourth side frame 14 along their length directions, preventing the first side frame 11, the second side frame 12, the third side frame 13, and the fourth side frame 14 from undergoing lateral deformation during use. 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. The design of the inverted T-shaped member 1111 forms a second C-shaped structure between it and the fourth receiving side plate 1104, and the opening of the second C-shaped structure faces away from the L-shaped member 1110 side. This design can be used to embed the second decorative clamping portion 2111 of the second inverted F-shaped member 211 to play a role in fixing and positioning.

[0050] Combined Figure 5 and Figure 10As shown, the number of the above-mentioned frame brackets 3 can be four, and the four frame brackets 3 are respectively inserted into the connection between the frame container 110 in the first frame 11 and the frame container 110 in the second frame 12, the connection between the frame container 110 in the second frame 12 and the frame container 110 in the third frame 13, the connection between the frame container 110 in the third frame 13 and the frame container 110 in the fourth frame 14, and the connection between the frame container 110 in the fourth frame 14 and the frame container 110 in the first frame 11. The frame brackets 3 are used to connect adjacent frame containers 110 to ensure that the door leaf frame 1 is firm and reliable. The design of the frame brackets 3 allows the connecting parts to be hidden inside the door leaf frame 1, avoiding exposed bolts or connection marks, and improving the overall aesthetics of the aluminum frame glass door panel.

[0051] The third accommodating side panel 1103 is provided with connection holes 11031 on either side along its length. These connection holes 11031 extend through the third accommodating side panel 1103 in a direction pointing toward the first accommodating side panel 1101, and their orthographic projections do not overlap at all with the orthographic projections of the first U-shaped structure 112. These connection holes 11031 are positioned independently and do not overlap with the first U-shaped structure 112, thereby avoiding structural conflicts.

[0052] Combine Figure 3 and Figure 5 As shown, the connection hole 11031 cooperates with the group frame corner bracket 3: the orthographic projection of the connection hole 11031 completely overlaps with the group frame corner bracket 3, and the position of the connection hole 11031 precisely matches the position of the group frame corner bracket 3. Fasteners 5 (such as bolts) can be connected to the group frame corner 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] Through the combination of the frame corner code 3 and the fastener 5, the connection between the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 becomes more secure. The frame corner code 3 provides additional support points, while the fastener 5 ensures that the frames do not loosen, thus enhancing the structural stability of the entire aluminum frame glass door panel. The position of the connection hole 11031 is designed such that the fastener 5 can be hidden inside the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 without being exposed. This hidden design is not only aesthetically pleasing but also avoids the risk of scratches or damage caused by exposed nail holes or bolt heads. The precise overlapping design of the connection hole 11031 and the frame corner code 3 ensures accuracy and reliability during the installation process. This design reduces installation errors, improves production efficiency, and also guarantees the overall quality of the aluminum frame glass door panel. This connection method allows for adjustment of the angles and positions between the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14, enabling the aluminum frame glass door panel to be finely adjusted according to different installation requirements. At the same time, the design of the hollow quadrilateral also facilitates the installation of glass or other materials. By hiding the fastener 5, the surface of the entire aluminum frame glass door panel is more concise and smooth, without obvious splicing marks or exposed connecting parts 310.

[0054] It should be noted that: the first receiving side plate 1101, the second receiving side plate 1102, the third receiving side plate 1103, the fourth receiving side plate 1104, the first C-shaped structure 112, the step part 113, the L-shaped part 1110 and the inverted T-shaped part 1111 are all integrally connected. The integral connection results in no splicing gaps between the various components, forming an integral structure, significantly enhancing the overall stability of the frame, and can also effectively prevent loosening or separation between the components, ensuring that the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 remain firm during use. It can be understood that: the integral connection method not only enhances the structural stability, improves the connection strength, but also simplifies the installation process, improves the overall aesthetics, reduces the maintenance cost, and improves the production efficiency.

[0055] Continue to refer to Figure 4As shown, the border decorative strip 2 is used to provide an aesthetically pleasing appearance, covering the surface of the border receiving member 110, making the aluminum frame glass door panel look neater and smoother. The border decorative strip 2 is formed by connecting a first decorative profile 21, a second decorative profile 22, a third decorative profile 23 and a fourth decorative profile 24 in sequence to form a rectangular frame. Each decorative profile is respectively covered on the corresponding border, that is, the first decorative profile 21 is covered on the first border 11, the second decorative profile 22 is covered on the second border 12, the third decorative profile 23 is covered on the third border 13, and the fourth decorative profile 24 is covered on 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 can protect the first border 11, the second border 12, the third border 13 and the fourth border 14 from external scratches and damage, thereby extending the service life of the door frame 1.

[0056] The first, second, third, and fourth decorative profiles 21, 22, 23, and 24 are composed of a first inverted F-shaped member 210 and a second inverted F-shaped member 211. These two parts are integrally connected, reducing the number of components and simplifying assembly. The material of the first, second, third, and fourth decorative profiles 21, 22, 23, and 24 is consistent with the material of the first, second, third, and fourth frames 11, 12, 13, and 14. When the first, second, third, and fourth frames 11, 12, 13, and 14 are made of aluminum, the material of the first, second, third, and fourth decorative profiles 21, 22, 23, and 24 is also aluminum.

[0057] Combine Figure 4 and Figure 5 As shown, the second inverted F-shaped member 211 in the first decorative profile 21 is located on the side of the first inverted F-shaped member 210 close to the third decorative profile 23, the second inverted F-shaped member 211 in the second decorative profile 22 is located on the side of the first inverted F-shaped member 210 close to the fourth decorative profile 24, the second inverted F-shaped member 211 in the third decorative profile 23 is located on the side of the first inverted F-shaped member 210 close to the first decorative profile 21, and the second inverted F-shaped member 211 in the fourth decorative profile 24 is located on the side of the first inverted F-shaped member 210 close to the first decorative profile 21. An outer decorative rectangular frame is formed between the first inverted F-shaped member 210 in the first decorative profile 21, the first inverted F-shaped member 210 in the second decorative profile 22, the first inverted F-shaped member 210 in the third decorative profile 23 and the first inverted F-shaped member 210 in the fourth decorative profile 24; an inner decorative rectangular frame is formed between the second inverted F-shaped member 211 in the first decorative profile 21, the second inverted F-shaped member 211 in the second decorative profile 22, the second inverted F-shaped member 211 in the third decorative profile 23 and the second inverted F-shaped member 211 in the fourth decorative profile 24.

[0058] The first inverted F-shaped part 210 is located on the side of the second inverted F-shaped part 211 close to the stepped part 113. It includes a first inverted L part 2101 and a first decorative snap-in part 2102 connected thereto. The side of the first inverted L part 2101 away from the second inverted F-shaped part 211 contacts the stepped part 113, playing a role in support and positioning. The first decorative snap-in part 2102 is snapped into the opening of the first C-shaped structure 112, and the decorative profile is fixed to the frame accommodating part 110 through this snap-in method.

[0059] The second inverted F-shaped part 211 includes a second inverted L part 2110 and a second decorative snap-in part 2111 connected to the second inverted L part 2110. The second decorative snap-in part 2111 is snapped 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 their tight combination with the frame accommodating part 110.

[0060] Through the design of the first inverted F-shaped part 210 and the second inverted F-shaped part 211, the connection between the frame decorative strip 2 and the door leaf frame 1 completely hides the fastener 5 between the frame decorative strip 2 and the door leaf frame 1, without exposed fasteners 5 (such as bolts, specifically bolt heads) and connection holes 11031 (such as nail holes), making the surface of the entire aluminum frame glass door panel cleaner and smoother. The frame decorative strip 2 completely covers the door leaf frame 1, forming an integral rectangular frame, which is more unified visually and enhances the overall aesthetics of the product. The first decorative snap-in part 2102 is snapped into the opening of the first C-shaped structure 112, and the second decorative snap-in part 2111 is snapped into the opening of the second C-shaped structure. This snap-in method not only fixes the decorative profile but also enhances the connection strength between the door leaf frame 1 and the frame decorative strip 2, preventing the frame decorative strip 2 from loosening or falling off during use.

[0061] Due to the use of the snap-in method, 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 the maintenance or replacement of the door leaf frame 1 or the core board 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 leaf frame 1 or the frame decorative strip 2, reducing the maintenance cost.

[0062] It should be noted that: along the direction from the second frame 12 to the fourth frame 14, the length of the first inverted F-shaped member 210 in the second decorative profile 22 and the fourth decorative profile 24 is greater than the length of the second inverted F-shaped member 211 in the second decorative profile 22 and the fourth decorative profile 24, and along the direction from the first frame 11 to the third frame 13, the length of the first inverted F-shaped member 210 in the first decorative profile 21 and the third decorative profile 23 is greater than the length of the second inverted F-shaped member 211 in the first decorative profile 21 and the third decorative profile 23, which is convenient for subsequently realizing the oblique connection between the first decorative profile 21 and the second decorative profile 22, the connection between the second decorative profile 22 and the third decorative profile 23, the connection between the third decorative profile 23 and the fourth decorative profile 24, and the connection between the fourth decorative profile 24 and the first decorative profile 21, such as a 45-degree oblique connection.

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

[0064] First, through the design of the first ⌚-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 first ⌚-shaped structure 112, the inverted T-shaped member 1111 in the frame connecting member 111, the connecting hole 11031 and the fastener 5 can be directly hidden between the first receiving side panel 1101 in the frame receiving member 110 and the corresponding frame decorative strip 2, avoiding the exposed connecting hole 11031, the fastener 5 (bolt) or other connection traces, making the surface of the aluminum frame glass door panel more neat and smooth. , that is, it can not only match the metal texture of the high-precision anodized surface, but also avoid the weak points of dust accumulation or water vapor intrusion at the connection hole 11031; the frame decorative strip 2 covers the surface of the frame receiving member 110 and the inverted T-shaped member 1111, which can prevent the frame receiving member 110 and the inverted T-shaped member 1111 from being scratched and damaged by the outside world, thereby extending the service life of the door leaf frame 1; the frame decorative strip 2 completely covers the frame receiving member 110 and the inverted T-shaped member 1111 of the door leaf frame 1, forming an integral rectangular frame, which is more visually unified and improves the overall aesthetics of the product;

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

[0066] Third, through the cooperation of the group frame corner code 3 and the fastener 5, a firm connection is achieved between the frame accommodating members 110, enhancing the structural strength of the entire door leaf frame 1. The hollow quadrilateral structure of the frame accommodating members 110 provides sufficient support strength while reducing weight, 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 accommodating members 110 and the inverted T-shaped members 1111 by snap connection, without using bolts or other fasteners 5, greatly simplifying the installation process, reducing the installation time and cost; the first C-shaped structure 112, the second C-shaped structure between the inverted T-shaped members 1111 and the frame accommodating members 110 provides an accurate positioning function, ensuring that different decorative profiles can be quickly and accurately installed in place; the snap connection design of the first decorative profile 21, the second decorative profile 22, the third decorative profile 23 and the fourth decorative profile 24 enables them to be easily disassembled, facilitating the maintenance or replacement of the frame decorative strip 2 and the door leaf 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 the maintenance cost.

[0068] In an optional embodiment, the connection holes 11031 include circular first connection holes 11031a and second connection holes 11031b; in the third accommodating side plates 1103 of the first frame 11 and the third frame 13, a first connection hole 11031a is respectively opened on one side close to the second frame 12 and on one side close to the fourth frame 14, and the number of the first connection holes 11031a is one; in the third accommodating side plates 11 of the second frame 12 and the fourth frame 14, a second connection hole 11031b is respectively opened on one side close to the first frame 11 and on one side close to the third frame 13, and the number of the second connection holes 11031b is two.

[0069] Specifically, as shown in Figure 3 and Figure 5 One first connection hole 11031a is respectively opened on both sides of the third accommodating side plate 1103 of the first frame 11 and the third frame 13 along its length direction. The shape of the first connection hole 11031a is circular, which is used to install the fastener 5, ensuring a firm and reliable connection between the first frame 11 and the group frame corner code 3, and between the third frame 13 and the group frame corner code 3, thereby enhancing the stability of the connection between the first frame 11 and the second frame 12, between the first frame 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] Two second connection holes 11031b are respectively provided on both sides of the third accommodating side panel 1103 along its length direction in the second frame 12 and the fourth frame 14. The second connection holes 11031b are circular in shape. By increasing the number of connection points, the connection strength between the second frame 12 and the group frame corner code 3 and between the fourth frame 14 and the group frame corner code 3 is further enhanced to prevent the door leaf frame 1 from loosening or deformation during use.

[0071] Using the above solution, the first and third frames 11 and 13 each have a first connection hole 11031a along their lengths, and the second and fourth frames 12 and 14 each have two second connection holes 11031b along their lengths. This symmetrical layout of the connection holes 11031 improves the structural balance of the entire aluminum-framed glass door panel, avoiding structural deformation caused by uneven distribution of connection points. The rational distribution of the connection holes 11031 also ensures that the aluminum-framed glass door panel is evenly stressed during use, extending its service life. The design of the connection holes 11031 allows the fasteners 5 (bolts) to be hidden within the first, second, third, and fourth frames 11, 12, 13, and 14, avoiding exposed nail holes or bolt heads and maintaining a clean and aesthetically pleasing surface. The clear location and number of the connection holes 11031 make installation simpler and faster. Installers can quickly and accurately install the fasteners 5 based on the pre-designed locations of the connection holes 11031. The pre-designed connection holes 11031 can also reduce errors during the installation process, thereby improving installation efficiency and quality.

[0072] In an alternative embodiment, combining Figure 5 、 Figure 6 and Figure 11 As shown, Figure 11 It is a structural schematic diagram of the frame corner code provided by the present invention; the frame corner code 3 includes a long connector 31 and a short connector 32 integrally connected to the long connector 31, and the long connector 31 and the short connector 32 form an L-shaped structure. The second frame 12 and the fourth frame 14 are respectively connected to the long connector 31 at one end close to the first frame 11 and the end close to the third frame 13, and the first frame 11 and the third frame 13 are respectively connected to the short connector 32 at one end close to the second frame 12 and the end close to the fourth frame 14.

[0073] Specifically, the number of group frame corner codes 3 can be four, and each group frame corner code 3 includes a long connector 31 and a short connector 32. The long connector 31 and the short connector 32 are integrated into a whole, and an L-shaped structure is formed between the long connector 31 and the short connector 32. Through the L-shaped structure, the group frame corner code 3 can simultaneously connect two adjacent frames, such as the adjacent 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] The two long connectors 31 are respectively connected to the two ends of the second frame 12 along its length direction, the other two long connectors 31 are respectively connected to the two ends of the fourth frame 14 along its length direction, the two short connectors 32 are respectively connected to the two ends of the first frame 11 along its length direction, and the other two short connectors 32 are respectively connected to the two ends of the third frame 13 along its length direction.

[0075] With the above scheme, the L-shaped structure formed by the long connector 31 and the short connector 32 can connect two adjacent frames at the same time to ensure that the connection between the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 is firm and reliable. This structural design can effectively prevent 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 achieve multi-point connection with other frames, further enhancing the structural stability of the entire door panel. The long connector 31 and the short connector 32 are connected in an integrated manner, reducing the number of components that need to be handled during the installation process and simplifying the installation steps. The installer can quickly and accurately connect the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 to the group frame corner bracket 3, thereby improving installation efficiency. The second frame 12 and the fourth frame 14 use long connectors 31 , and 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 an optional embodiment, a connecting portion 310 is provided on the side of the long connector 31 away from the short connector 32 and on the side of the short connector 32 away from the long connector 31. A third connecting hole 3101 corresponding to the second connecting hole 11031b is defined on the connecting portion 310 of the long connector 31, and a fourth connecting hole 3102 corresponding to the first connecting hole 11031a is defined on the connecting portion 310 of the short connector 32.

[0077] The fastener 5 includes a first fastener 51 and a second fastener. The first fastener 51 connects the third accommodating side panel 1103 in the second frame 12 and the fourth frame 14 and the connecting portion 310 in the long connector 31 through the second connecting hole 11031b and the third connecting hole 3101. The second fastener connects the third accommodating side panel 1103 in the first frame 11 and the third frame 13 and the connecting portion 310 in the short connector 32 through the first connecting hole 11031a and the fourth connecting hole 3102.

[0078] Specifically, combined Figure 5 and Figure 11 As shown, the connection portion 310 of the long connector 31, the connection between the long connector 31 and the short connector 32, and the connection portion 310 of the short connector 32 form a triangular structure. The triangular structure not only evenly distributes external forces to the three vertices, thereby 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 localized excessive stress, and extend service life. A third connection hole 3101 is provided in the connection portion 310 of the long connector 31. The third connection hole 3101 corresponds to and communicates with the second connection hole 11031b in the second frame 12 and the fourth frame 14; the connection portion 310 of the short connector 32 has a fourth connection hole 3102, which corresponds to and communicates with the first connection 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 with the long connector 31 through the second connecting hole 11031b (the second connecting hole 11031b is opened on the third accommodating 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 on the connecting portion 310 of the long connector 31).

[0080] The second fastener connects the first frame 11 and the third frame 13 with the short connector 32 through the first connecting hole 11031a (the first connecting hole 11031a is opened on the third accommodating 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 on the connecting portion 310 of the short connector 32).

[0081] Using the above solution, the second frame 12 and the fourth frame 14 are connected to the long connector 31 through the first fastener 51 and the second fastener, and the first frame 11 and the third frame 13 are connected to the short connector 32. This multi-point connection method ensures that the connection between the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 and the group frame corner code 3 is more secure, effectively preventing loosening or falling off. The corresponding design of the connecting hole 11031 (the second connecting hole 11031b and the third connecting hole 3101, 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 hole 11031, avoiding exposed bolts (such as bolt heads) and keeping the surface of the aluminum frame glass door panel clean and beautiful.

[0082] The first and third frames 11 and 13 use short connectors 32, while the second and fourth frames 12 and 14 use long connectors 31. This symmetrical connection method makes the entire door panel more structurally balanced. By rationally distributing the connection points, the aluminum-framed glass door panel is evenly stressed during use, extending its service life.

[0083] In an alternative embodiment, combining Figure 5 、 Figure 9 、 Figure 12 and Figure 13 As shown, Figure 12 This is a schematic diagram of the assembly of the fourth frame, part of the first frame, and the frame corner bracket provided by the present invention; Figure 13 This is a rear view of an aluminum-framed glass door panel with hidden nail holes provided by the present invention; hinge openings are respectively provided on the first accommodating side panel 1101 of the fourth frame 14 near the first frame 11, the first accommodating side panel 1101 of the first frame 11 near the fourth frame 14 and near the second frame 12, and the first accommodating side panel 1101 of the second frame 12 near the first frame 11; the hinge opening of the first accommodating side panel 1101 in the fourth frame 14 is connected to the hinge opening of the first accommodating side panel 1101 in the first frame 11 near the fourth frame 14 to form a first L-shaped hinge opening 11011; the hinge opening of the first accommodating side panel 1101 in the second frame 12 is connected to the hinge opening of the first accommodating side panel 1101 in the first frame 11 near the second frame 12 to form a second L-shaped hinge opening 11012, and the top angle of the first L-shaped hinge opening 11011 faces the top angle of the second L-shaped hinge opening 11012.

[0084] Specifically, a rectangular hinge opening is provided at one end of the first accommodating side panel 1101 in the fourth frame 14 close to the first frame 11, and the hinge opening of the first accommodating side panel 1101 in the fourth frame 14 is recessed toward the third frame 13. Rectangular hinge openings are respectively provided at both ends of the first accommodating side panel 1101 in the first frame 11 along its length direction, and the hinge opening of the first accommodating side panel 1101 in the first frame 11 close to the fourth frame 14 is recessed toward the second frame 12. The hinge opening of the first accommodating side panel 1101 in the first frame 11 close to the second frame 12 is recessed toward the fourth frame 14. A rectangular hinge opening is provided at one end of the first accommodating side panel 1101 in the second frame 12 close to the first frame 11, and the hinge opening of the first accommodating side panel 1101 in the second frame 12 is recessed toward the third frame 13.

[0085] A first L-shaped hinge opening 11011 is formed between the hinge opening of the first accommodating side panel 1101 in the fourth frame 14 and the hinge opening of the first accommodating side panel 1101 in the first frame 11. A second L-shaped hinge opening 11012 is formed between the hinge opening of the first accommodating side panel 1101 in the first frame 11 and the hinge opening of the first accommodating side panel 1101 in the second frame 12. The first L-shaped hinge opening 11011 and the second L-shaped hinge opening 11012 make the connection between the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 more intuitive and simple. Installers can quickly align different frames based on 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 collection cabinet based on the position of the hinge openings and secure the door frame 1 to the cabinet body of the wine collection cabinet via the frame assembly angle bracket 3. Because the hinge openings have preset connection positions, no additional measuring or marking tools are required during installation, further simplifying the installation steps.

[0086] In an optional embodiment, along the direction of the third accommodating side panel 1103 pointing to the first accommodating side panel 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 accommodating side panel 1101.

[0087] Specifically, combined Figure 9 and Figure 10As shown, along the direction from the first accommodation side plate 1101 to the third accommodation 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 clamping part 2111 is clamped into the opening of the second C-shaped structure, after the inner wall of the second inverted F-shaped part 211 is closely attached to the side of the inverted T-shaped part 1111 away from the fourth accommodation side plate 1104, it can also be flush with the surface of the L-shaped part 1110 away from the first accommodation side plate 1101. The surfaces of the second inverted F-shaped part 211 and the L-shaped part 1110 look continuous without obvious steps.

[0088] In an optional embodiment, the contact surfaces between the middle frame accommodating part 110 of the first frame 11 and the middle frame accommodating part 110 of the second frame 12, between the middle frame accommodating part 110 of the second frame 12 and the middle frame accommodating part 110 of the third frame 13, between the middle frame accommodating part 110 of the third frame 13 and the middle frame accommodating part 110 of the fourth frame 14, and between the middle frame accommodating part 110 of the fourth frame 14 and the middle frame accommodating part 110 of the first frame 11 are all the first inclined surfaces 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] As shown in 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 can not only provide a better contact area and support effect, but also the contact of the bevels (such as the first bevel 114 and the second bevel 212) can better disperse stress and reduce local excessive force compared to plane contact, 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 border decorative strip 2 more symmetrical, further improving the balance of the entire aluminum frame glass door panel, ensuring that it will not be deformed due to uneven force 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 border decorative strip 2 more natural, reduces obvious splicing marks, and makes the door panel surface smoother and tidier.

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

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

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

[0096] The core panel 4 is a crucial component of an aluminum-framed glass door panel, typically providing additional strength, thermal insulation, or soundproofing. It's embedded within the rectangular frame formed by the spaces within the first, second, third, and fourth frames 11, 12, 13, and 14. Specifically, the core panel 4 is mounted within these three frames, forming a single, integrated unit.

[0097] The core board 4 is embedded in the accommodation spaces of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14, which can provide additional support for the entire aluminum-frame glass door panel and enhance the overall structural stability of the aluminum-frame glass door panel. The presence of the core board 4 makes the aluminum-frame glass door panel more robust during use and capable of withstanding greater external forces. The core board 4 can disperse stress, reduce the deformation of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 when stressed, and extend the service life of the aluminum-frame glass door panel.

[0098] By embedding the core board 4 inside the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14, the heat insulation and sound insulation effects of the aluminum-frame glass door panel can be effectively improved, enhancing the functionality of the aluminum-frame glass door panel. The embedding of the core board 4 makes the aluminum-frame glass door panel not only aesthetically pleasing but also have practical heat insulation and sound insulation functions, suitable for various application scenarios, such as indoor partitions, cabinet doors, wine storage cabinets, etc.

[0099] As can be seen from the above embodiments, the aluminum-frame glass door panel with hidden nail holes provided by the present invention achieves at least the following beneficial effects:

[0100] First, through the design of the first C-shaped structure, the frame accommodation part, the frame connecting parts (such as L-shaped parts and inverted T-shaped parts), and the frame decorative strip, the first C-shaped structure, the frame connecting parts, the connecting holes and the fasteners are hidden inside, avoiding exposed connecting holes (such as nail holes), fasteners (bolts) or other connecting traces, making the surface of the aluminum-frame glass door panel cleaner and smoother. That is, it can not only match the metallic texture of the high-precision anodic oxidation surface but also avoid the weak points where dust accumulates or water vapor intrudes at the connecting holes; the frame decorative strip covers the surfaces of the frame accommodation part and the inverted T-shaped part, which can prevent the frame accommodation part and the inverted T-shaped part from being scratched and damaged by the outside world, extending the service life of the door leaf frame; the frame decorative strip completely covers the frame accommodation part and the inverted T-shaped part of the door leaf frame, forming an integral rectangular frame, which is more visually unified and enhances the overall aesthetics of the product;

[0101] Second, through the first inverted F-shaped part and the second inverted F-shaped part, the first decorative profile, the second decorative profile, the third decorative profile and the fourth decorative profile have a simple structure without redundant decorations or protruding parts; the frame decorative strip is firmly fixed on the frame accommodation part and the inverted T-shaped part through the snap connection design of the first inverted F-shaped part and the second inverted F-shaped part, further enhancing the integrity of the door leaf frame.

[0102] Third, the combination of framing brackets and fasteners creates a secure connection between the frame and the frame, enhancing the structural strength of the entire door frame. The hollow quadrilateral structure of the frame reduces weight while providing sufficient support strength to prevent deformation or damage during use of the aluminum-framed glass door panel.

[0103] Fourth, the border decorative strip is fixed to the border receiving piece and the inverted T-shaped piece by a clip-on method, without the use of bolts or other fasteners, which greatly simplifies the installation process and reduces installation time and cost; the second ⌚-shaped structure between the first ⌚-shaped structure, the inverted T-shaped piece and the border receiving piece provides a precise positioning function, ensuring that different decorative profiles can be installed in place quickly and accurately; the clip-on design of the first decorative profile, the second decorative profile, the third decorative profile and the fourth decorative profile allows them to be easily disassembled, which is convenient for maintenance or replacement of the border decorative strip and the door frame. If the first decorative profile, the second decorative profile, the third decorative profile and / or the fourth decorative profile are damaged, they can also be replaced individually without replacing the entire border decorative strip, reducing maintenance costs.

[0104] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may 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.
