Description

Technical Field

[0001] This invention belongs to the field of cabinet structure and furniture hardware technology, specifically relating to a split-frame cabinet structure. Background Technology

[0002] Existing frame cabinets (such as shelving cabinets and storage cabinets) typically use a one-piece upright and one-piece door structure. While this one-piece structure provides a stable connection, the individual components are long, bulky, and heavy, requiring significant packaging space and making them prone to bumps and damage during handling due to their large size. To optimize handling, some products adopt a modular structure, separating the uprights and doors into upper and lower sections for separate packaging, and then assembling them at the site. However, existing modular cabinets have significant structural defects after assembly, as follows: First, functional separation leads to structural redundancy. In existing technologies, door fixing, side panel fixing, and anti-detachment of separate columns are all accomplished by independent connectors: the door is installed to the column via hinges, the side panels are fixed to the column with special fasteners, and additional connectors or locking structures are required to reinforce the connection points of the separate columns. This "single function, independent component" design mode results in a large number of connectors, cumbersome installation procedures, and high redundancy in the cabinet structure.

[0003] Second, the rigidity of the split door panels is insufficient. During the opening and closing process, the rigidity at the joint of the split door panels decreases significantly, making them prone to flexible deformation. This can lead to problems such as poor door closure and incomplete shutting. After long-term use, permanent deformation of the door is likely to occur, affecting its performance.

[0004] Third, the locking effect of the split columns is poor. The connection between the split columns lacks a reliable locking structure, making them prone to loosening and displacement during use, which directly reduces the overall structural stability and safety of the cabinet.

[0005] Fourth, the hinges and fasteners have limited functionality and suffer from technological bias. In existing technologies, hinges only serve the function of opening and closing the door, and hinge fasteners are only used to fix the hinge body, resulting in a limited and unexpanded functionality. Those skilled in the art have long held a technological bias, treating hinge fasteners and other cabinet structural fasteners as independent components, failing to realize that multiple components can be locked synchronously using the same fastener.

[0006] To address the aforementioned problems, it is necessary to design a modular frame cabinet structure that overcomes the drawbacks of modular cabinets, such as easy bending and deformation of the door panels during opening and closing, easy loosening of the modular columns, numerous connectors, and complex installation procedures. To this end, the applicant has developed a beneficial design, and the technical solution described below arose from this context. Summary of the Invention

[0013] In another specific embodiment of the present invention, the lower edge of the upper side plate is bent to form an upper side plate connecting edge, and the upper edge of the lower side plate is bent to form a lower side plate connecting edge. The upper side plate connecting edge and the lower side plate connecting edge are fixedly connected by side panel fasteners.

[0014] In a further specific embodiment of the present invention, a back panel is also provided on the rear side of the cabinet. The back panel is a split back panel, and the back panel has at least two split back panel parts along the height direction. The connection between two adjacent split back panel parts is bent with a back panel connecting edge, and the adjacent back panel connecting edges are fixedly connected by back panel fasteners. The two sides of the back panel are pressed and fixed by the side panels on both sides, further preventing the front column split parts and the rear column split parts from separating from each other.

By making the joints of the side panel sections and the column sections non-coplanar, the shear force can be effectively dispersed and transmitted when the side panel is subjected to external force, inhibiting the separation of the column sections and significantly improving the connection strength and overall stability of the column sections. Second, the side panel also has the function of locking the column sections to prevent them from falling off. After the side panel sections are fixed to each other, they are completely covered and fastened to the outside of the column. The overall structure of the side panel constrains and locks the column sections, realizing the functional upgrade of the side panel from a simple covering to a key structural component. Third, the hinge serves as both the side panel and the front column. The locking mechanism, while ensuring normal opening and closing of the door, uses fasteners to simultaneously penetrate the door, side panels, and front uprights, securing them together as a single unit and further enhancing the anti-detachment function of the front uprights and the overall connection reliability. Fourth, the split back panel also functions as an anti-detachment locking mechanism for the rear uprights. After the split parts of the back panel are fixedly connected, the two side edges are pressed and positioned by the side panels, enabling it to function as both a cabinet closure and an anti-detachment locking structure for the rear uprights, achieving multiple uses with a single panel and a simplified structure. Fifth, it facilitates separate packaging and transportation. By designing the uprights, side panels, door panels, and back panel as separate structures, the length of individual components, packaging volume, and weight of individual items are effectively reduced, significantly improving the convenience of handling, storage, and transportation.

[0029] Please see Figure 2 and combined Figure 3 The door body 1 comprises an upper door body 11 and a lower door body 12. A pair of upper door body hinges 113 are spaced vertically at the connection between the upper door body 11 and the cabinet body 10. One side of each upper door body hinge 113 is fixedly connected to the upper door body 11 via a first upper door body hinge fastener 1131, and the other side of each upper door body hinge 113 is fixedly connected to the corresponding side panel 5 and the front pillar 3 via a second upper door body hinge fastener 1132. A pair of lower door body hinges 123 are spaced vertically at the connection between the lower door body 12 and the cabinet body 10. One side of each lower door body hinge 123 is fixedly connected to the lower door body 12 via a first lower door body hinge fastener 1231, and the other side of each lower door body hinge 123 is fixedly connected to the corresponding side panel 5 and the front pillar 3 via a second lower door body hinge fastener 1232. The connecting member 13 is located between the upper door body 11 and the lower door body 12.

[0030] Furthermore, at least two upper door body reinforcing beams 111 are spaced apart in the width direction of the upper door body 11. In this embodiment, the number of upper door body reinforcing beams 111 is preferably three. The upper door body hinges 113 are respectively fixed on the upper door body reinforcing beams 111. The upper door body reinforcing beams 111 respectively form upper door body reinforcing beam cavities 1111 that run vertically along their length direction. An upper connecting member clearance opening 112 is provided on the side of the upper door body 11 facing the lower door body 12 and at a position corresponding to the upper door body reinforcing beam cavity 1111. At least two lower door body reinforcing beams 121 are spaced apart in the width direction of the lower door body 12. In this embodiment... Preferably, there are three lower door body reinforcing beams 121, and the lower door body hinges 123 are respectively fixed on the lower door body reinforcing beams 121.

[0032] Please see Figures 1 to 4 Firstly, by making the connection points between the side panel components and the connection points between the front and rear column components non-coplanar, the splicing seams of the side panel components and the connection seams of the front and rear column components are staggered in the height direction. When the front column 3 and rear column 4 are subjected to external forces, the side panel 5 can disperse and transmit the shear force, preventing the external force from directly acting on the connection seams between the front and rear column components, thereby effectively preventing the front and rear column components from separating from each other. At the same time, the side panel 5 is semi-enclosed and fixed to the front column 3 and rear column 4 by the side panel edging 53, further enhancing the connection strength between the side panel 5 and the front and rear columns 3 and 4. Secondly, after the back panel sections are fixedly connected to each other, their two sides are pressed together by the side panels 5 on both sides, transforming the back panel 7 from a single covering into a component that combines sealing and structural reinforcement functions, further preventing the rear column sections from separating. Thirdly, while enabling the door 1 to open and close, the hinge's fasteners simultaneously pass through the door 1, side panels 5, and front column 3, fixing the three together as a single unit. This transforms the hinge from a single door opening and closing component into an integrated component with three functions: door 1 opening and closing, side panel 5 fixation, and front column section anti-detachment. Finally, through the multi-dimensional coordinated locking of the side panels 5, back panel 7, and hinges, this invention achieves all-around anti-detachment of the split columns, significantly improving the overall stability of the split cabinet.

[0033] In summary, the technical solution provided by this invention overcomes the deficiencies in the prior art, successfully completes the invention task, and accurately realizes the technical effects recorded by the applicant in the above-mentioned technical effects column.
