Description

Technical Field

[0001] This utility model relates to the field of custom cabinet assembly technology, and in particular to a concealed connection structure for custom cabinet panels. Background Technology

[0002] Custom cabinets are a common project in home renovation, typically requiring personalized design and installation based on the interior space layout. The process usually involves multiple stages, including measurement, fabrication, and on-site assembly, embedding prefabricated panels into the target area and integrating them into a unified cabinet structure. However, during actual construction, due to inherent structural errors, measurement deviations, limitations in fabrication precision, and limitations in installation techniques, gaps or irregular spaces often exist between the cabinet and the building interface, making perfect matching difficult. To conceal these defects and improve the overall aesthetics, edge banding is usually added to the outer edge of the cabinet, cut and adjusted on-site according to the actual dimensions, and finally sealed with silicone sealant.

[0003] In existing installation processes, edge banding panels are mostly connected and fixed to the cabinet side panels using corner brackets. While this method is simple in structure, it lacks necessary tolerance and adjustability. If the corner bracket mounting holes deviate, or if the edge banding panels are not dimensionally consistent due to processing or on-site measurement errors, the relative position between the edge banding panel and the cabinet becomes difficult to adjust, easily leading to misalignment, unevenness, or uneven gaps, affecting the overall aesthetics and installation quality. Furthermore, this rigid connection method reduces installation efficiency and increases rework and modification costs. Therefore, a more adaptable and adjustable edge banding panel installation structure is urgently needed to improve the installation accuracy and overall finishing quality of custom cabinets.

[0026] Example Reference Figures 1 to 4 The present invention proposes a concealed connection structure for a custom cabinet panel, which is used to connect and fix a first panel 10 and a second panel 20 that are vertically arranged, including a male component 30 installed on the first panel 10 and a female component 40 installed on the second panel 20. The male component 30 includes a male seat 31 fixed to the first plate 10, and the male seat 31 has a insertion slot 32 perpendicular to the second plate 20; the female component 40 is T-shaped in general, including a female seat 41 fixed to the second plate 20, and an insertion post 42 extending perpendicular to the second plate 20; the insertion post 42 can be inserted into the insertion slot 32. The upper and / or lower sides of the plug post 42 are provided with a plurality of longitudinally toothed plug-in connection portions 43; the upper and lower sides of the plug groove 32 are provided with groove sidewalls 33 extending in a direction perpendicular to the second plate 20; the groove sidewalls 33 are provided with at least one longitudinally toothed plug-in limiting portion 34; the plug-in limiting portion 34 can engage with the plug-in connection portions 43 and restrict the movement of the plug post 42 in the depth direction of insertion into the plug groove 32; the groove sidewalls 33 can elastically deform outward; There are gaps between the upper, lower, left and right sides of the plug post 42 and the plug slot 32; the plug post 42 can move toward the upper, lower, left and right sides of the plug slot 32.

[0027] The beneficial effects of this utility model are: 1. Achieves multi-dimensional flexible adjustment, significantly improving fault tolerance and installation accuracy: The design of "a gap between the plug-in post 42 and the plug-in slot 32" allows the sealing plate (second plate 20) to be finely adjusted in four directions (up, down, left, and right) relative to the cabinet (first plate 10) after the male part 30 and the female part 40 are connected. This feature effectively compensates for misalignment caused by drilling deviation, uneven walls, or board processing errors, ensuring the alignment and uniformity of gaps between the sealing plate and the cabinet, as well as between the sealing plate and the ceiling / floor / wall, greatly improving the overall aesthetics after installation.

[0028] 2. Simplified installation process and improved installation efficiency: During installation, simply align the female connector 40's plug-in post 42 and insert it into the male connector 30's plug-in slot 32 to complete the initial assembly. Then, pre-assemble and position the sealing plate (second plate 20) relative to the cabinet (first plate 10), and then tighten the male connector 31 and female connector 41 to the cabinet (first plate 10) and sealing plate (second plate 20) respectively with screws. Finally, assemble again within the designed space. The elastic deformation characteristics of the plug-in slot 32's sidewalls make the insertion process smooth and effortless, eliminating the need for time-consuming precise alignment. This "foolproof" plug-in operation, compared to traditional corner bracket connections that require multiple alignments and tightening of screw holes, greatly simplifies the operation steps, reduces the skill requirements for workers, and thus significantly improves installation efficiency.

[0029] 3. Achieve "hidden" connections for enhanced aesthetics: All connecting parts (male part 30, female part 40) are pre-installed on the inside of the panels, and the final connection is completed internally. No connecting parts (such as corner brackets, screw heads, etc.) are visible from the outside, ensuring a clean and unified appearance of the cabinet side and panel, achieving a minimalist, integrated, and high-end visual effect.

[0030] In this embodiment, the side of the insertion slot 32 facing the female seat 41 is provided with an outwardly inclined, funnel-shaped guide connecting wall 35. This significantly reduces the difficulty of the insertion operation and the accuracy requirements for alignment. This guide structure can guide the slightly deviated insertion post 42 to slide smoothly into the insertion slot 32, avoiding the trouble of repeatedly trying to align due to minor misalignment during installation, further enhancing the "foolproof" installation experience and speeding up the assembly process, especially when operating in a space-constrained cabinet.

[0031] Furthermore, the end of the connector 42 that connects to the female connector 41 is provided with an outwardly angled, flared guide connection portion 44. The guide connection portion 44 and the guide connection wall 35 form a double guiding guarantee, allowing the male component 30 and female component 40 to be smoothly guided into the correct insertion path from more angles during mating. This further enhances the fault tolerance capability, enabling easy correction through the interaction of the two guide surfaces even with large initial deviations, ensuring successful insertion on the first attempt and greatly improving the ease of installation and reliability.

[0032] In this embodiment, the insertion slot 32 is provided with a plurality of transversely toothed transverse connecting portions 36 on the upper and / or lower side of the side facing the female seat 41; the female seat 41 is provided with at least one transversely toothed transverse limiting portion 45 on the side facing the insertion slot 32, the transverse limiting portion 45 being located at the root of the insertion post 42; the transverse limiting portion 45 can engage with the transverse connecting portions 36 and restrict the transverse movement of the insertion post 42 on the left or right side of the insertion slot 32. After the user moves the sealing plate left and right to find the optimal position, the engagement of the transverse teeth can effectively limit the accidental movement or loosening of the sealing plate in the left and right directions, firmly locking the sealing plate in the adjusted position, thereby ensuring the stability and reliability of long-term use and avoiding positional deviation caused by external force or vibration.

[0033] In this embodiment, a support top 37 is provided at the top of the insertion slot 32 away from the male seat 31 on the side facing the female seat 41; the support top 37 protrudes towards the female seat 41 relative to the side of the male seat 31. The second plate 20 serves as a sealing plate and is set perpendicular to the cabinet of the first plate 10; however, in the area away from the cabinet, tilting deformation towards the cabinet side is easily generated during the pushing process. By providing a support top 37 at the top of the insertion slot 32 away from the male seat 31, and pushing the support in the opposite direction to the female seat 41, the inward tilting deformation of the first plate 10 and the female seat 41 can be overcome, making the sealing plate of the second plate 20 more perpendicular and flat to the first plate 10 after installation. This ensures that the sealing plate and the side of the cabinet achieve a truly seamless fit, avoiding visible gaps and greatly improving the aesthetics and premium feel of the final product.

[0034] In this embodiment, the distance d between the support top 37 and the side of the male seat 31 protruding towards the female seat 41 is between 0.2 mm and 0.5 mm. This ensures optimal compensation and prevents installation difficulties or stress concentration due to excessive protrusion.

[0035] Preferably, the distance between the support top 37 and the side of the male seat 31 protruding towards the female seat 41 is 0.3 mm.

[0036] In this embodiment, the insert post 42 has a hollow internal structure; the insert post 42 is provided with reinforcing ribs 46 inside. The hollow structure saves materials, reduces costs and weight, and also reduces defects caused by injection molding collapse; the internal reinforcing ribs 46 ensure the insert post 42's resistance to bending and deformation during repeated insertion and removal and use, ensuring the reliability of the toothed structure engagement and the long service life of the connection structure, and avoiding the failure or loosening of the adjustment function due to component deformation.

[0037] In this embodiment, the male connector 31 has screw holes 50 on the outer sides of the left and right sides of the insertion slot 32; the female connector 41 has screw holes 50 on the outer sides of the left and right sides of the insertion post 42; the screw holes 50 are used to insert screws. The screw connection ensures that the male and female components 30 can be securely installed on the cabinet and the sealing plate respectively, providing a stable foundation for subsequent insertion and adjustment operations. At the same time, this connection method is simple to construct, uses readily available tools, and is very convenient for on-site installation.

[0038] Furthermore, screw holes 50 are countersunk holes; in the projection direction of screw holes 50 on male connector 31, there is no interference from female connector 40; in the projection direction of screw holes 50 on female connector 41, there is no interference from male connector 30. Countersunk holes allow the screw head to be recessed into the component, not protruding from the surface, avoiding interference with the installation of other components or hand injuries. Secondly, the "no interference in projection direction" design allows the screwdriver to be screwed into the male connector 30 or female connector 40 vertically and without obstruction by the component on the other side (male connector 30 or female connector 40) when installing screws on the male connector 30 or female connector 40. This greatly facilitates on-site construction operations, avoids the predicament of not being able to use installation tools due to insufficient space, and improves installation efficiency.

[0039] In this embodiment, a conical recess 51 is provided at the bottom end of the screw hole 50 facing the board body. The conical recess 51 is used to collect wood chips or debris. By collecting wood chips or debris from the board body through the conical recess 51, the male seat 31 or female seat 41 can be prevented from being partially lifted and tilted when screwing.

[0040] The male connector 31 has a clearance notch 38 on the side facing the screw hole 50 of the female connector 41. The clearance notch 38 is used to avoid the head of the screw. The clearance notch 38 provides additional clearance space for the screw of the female connector 41. When the screw of the female connector 41 is not driven straight, tilted or bent and protrudes, the screw can avoid interfering with the male connector 31 when the female connector 40 is adjusted left or right.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
