[0030] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, and cannot be understood as limiting the utility model. Example 1

[0031] like Figure 1-Figure 5As shown, the utility model is a corner connection assembly and an assembled cabinet, and the corner connection assembly is applied to the frame assembly of cabinets such as sideboards and tea cabinets. The cabinet structurally includes a cabinet frame 1 and a vertical mounting plate 2 and a horizontal mounting plate 3 fixed on the cabinet frame 1. The vertical mounting plate 2 and the horizontal mounting plate 3 can be made of plate structures such as glass plates and aluminum plates. The cabinet frame 1 includes a vertical rod 1-1, a horizontal rod 1-2 and the corner connection assembly 1-3, and the vertical rod and the horizontal rod are respectively connected and matched with the corner connection assembly.

[0032] The corner connection assembly 1-3 includes a corner piece body 1-31 and a vertical connection pipe 1-32, and the corner piece body 1-31 and the vertical connection pipe 1-32 are movably connected and matched. The corner piece body 1-31 includes a fixed base 1-311 and a horizontal connection pipe 1-312 horizontally connected to the fixed base 1-311. The fixed base 1-311 is generally set to be T-shaped or L-shaped. The T-shaped fixed base 1-311 needs to be connected to the horizontal rods 1-2 on both sides, while the L-shaped fixed base 1-311 is provided with a rounded arc surface on the outer side, so that the edge of the cabinet is smoother and the lines are more streamlined.

[0033] The fixed base 1-311 is provided with a first positioning socket 1-3111 and a second positioning socket 1-3112, and the ends of the vertical connecting pipe 1-32 are respectively provided with a first connector 1-321 and a second connector 1-322, the first connector 1-321 is plugged with the first positioning socket 1-3111, and a positioning end plate 1-323 is provided at the lower part of the first connector 1-321, and the corners of the positioning end plate are set as right angles to improve the stability of positioning. The second connector 1-322 is plugged with the second positioning socket 1-3112, so that the vertical connecting pipe can be firmly positioned on the fixed base 1-311 to avoid left and right shaking. In order to further enhance the stability of the connection between the fixed base 1-311 and the vertical connecting pipe fitting 1-32, it is necessary to provide a mutually interlocking block 4 and a card slot 5 between the side of the second connector and the inner wall of the second positioning socket. In this embodiment, the card block is arranged on the inner side of the second positioning socket, and the card slot 5 is arranged on the outer side of the second connector; when the second connector is inserted into the second positioning socket, the card block 4 and the card slot 5 can be interlocked; the first connector and the second connector of the vertical connecting pipe fitting are simultaneously inserted into the corresponding positioning sockets of the fixed base. Since the card block 4 and the card slot 5 are interlocked, it is difficult for the vertical connecting pipe fitting to be separated from the fixed base. Basically, after the vertical connecting pipe fitting is inserted into the fixed base, it is difficult to separate the two except by using violent means such as cutting, hammering, etc. This is particularly important for the stability of the entire cabinet frame.

[0034] Furthermore, the first positioning socket is L-shaped, and the first connector 1-321 is a positioning column with an L-shaped cross section; in this embodiment, the first connector 1-321 includes a vertically arranged connecting end plate 1 and a connecting end plate 2, and the connecting end plate 1 and the connecting end plate 2 are perpendicular to each other and are integrally formed with the main body of the vertical connecting pipe. The second connector 1-322 is a tubular structure, and a core member 1-3221 is arranged in the second connector, and the core member is composed of a plurality of integrally formed plate members, and the core member is connected to the inner wall of the second connector as a whole, which greatly increases the bending strength of the second connector and facilitates insertion into the second positioning socket without bending. A transverse card block 1-3211 is arranged on the side of the first connector, and the transverse card block is consistent with the shape of the L-shaped first connector, but is provided with an inclined surface to facilitate the engagement and matching of the transverse card block with the first positioning socket. The first connector 1-321 is provided with positioning protrusions 1-3212 extending outward on both sides, and the positioning protrusions are movably pressed together with the end of the first positioning socket, and the positioning protrusions play a limiting role, so that the docking structure between the first connector and the first positioning socket is more stable. A longitudinal plate 1-3113 and a transverse plate 1-3114 are provided in the fixed base 1-311, and the longitudinal plate and the transverse plate are cross-connected as a whole, and divide the internal cavity of the fixed base into a first positioning socket, a second positioning socket, a third slot and a fourth slot. Ribs are provided on the top of the longitudinal plate and the transverse plate, and a spacing position is provided between the first connector and the second connector to allow the longitudinal plate and the transverse plate to be inserted at the intersection. Example 2

[0035] like Figure 6 and Figure 7 As shown, in this embodiment, the cross-section of the second connector is fan-shaped, and two outwardly extending card blocks 6 are respectively provided on the two side surfaces of the second connector. Correspondingly, a second card slot 7 is provided in the second positioning socket of the fixed base, and the card block 2 is engaged with the card slot 2 to achieve stability of the connection between the two.

[0036] Compared with the prior art, the corner connection assembly of the utility model can be disassembled. This disassembly form determines that some parts of the corner connection assembly can be assembled with part of the frame of the cabinet and then packed before leaving the factory, which greatly improves the efficiency of users in assembling cabinets, reduces the difficulty of installation, and can reduce packaging costs and logistics transportation costs. For example, the volume of the packaging carton will be reduced, and a container can accommodate more packaged products. In addition, in order to improve the stability of the assembly structure between the various parts after disassembly, a double-plug and double-connection socket corresponding card connection structure is adopted, and the snap-fit ​​cooperation between the card block and the card slot inside the plug and the socket is coordinated, which further enhances the overall stability of the assembled corner connection assembly. After being assembled into a cabinet, the cabinet is stronger and more durable.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
