Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0047] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0048] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0049] like Figures 1-6 As shown, the cabinet structure of a cabinet of this embodiment mainly includes: a first side frame 1, a second side frame 2, multiple beams and multiple corner connecting joints, wherein the first side frame 1 and the second side frame 2 each include two first profiles 11 and two second profiles 12; the multiple beams include two upper beams 3A and two lower beams 3B; the multiple corner connecting joints include multiple upper corner connecting joints 4A and multiple lower corner connecting joints 4B.
[0050] The first side frame 1 and the second side frame 2 are spaced apart and are both rectangular. The ends of the crossbeam are fixedly connected to the first side frame 1 and the second side frame 2 via a corner joint. The corner joint includes a first connector 41 and a second connector 42, which are separately provided. When the crossbeam is fixedly connected to the first side frame 1 / second side frame 2 via the corner joint, the first connector 41 can be first fixedly connected to the first side frame 1 / second side frame 2, specifically by welding; the second connector 42 can be first fixedly connected to the crossbeam, also by welding; and then the first connector 41 and the second connector 42 can be connected.
[0051] When assembling the cabinet, the customer can first secure the first connector 41 to the first side frame 1 and the second side frame 2, and secure the second connector 42 to the crossbeam. The first connector 41 and the second connector 42 can then be connected. The split corner connector eliminates the need to connect the profiles one by one to the corner connector, effectively simplifying assembly and improving assembly efficiency. The overall structure is simple, reducing cabinet costs. Furthermore, the split corner connector offers strong scalability and design flexibility. The first connector 41 or the second connector 42 can be structurally adjusted based on profiles of different cross-sections, allowing the corner connector to securely connect the cabinet corners.
[0052] Specifically, the first side frame 1 and the second side frame 2 each include two first profiles 11 arranged in parallel and two second profiles 12 arranged in parallel between the two first profiles 11. The first profile 11 is perpendicular to the second profile 12, and the length of the first profile 11 is greater than the length of the second profile 12. The cross-sections of the first profile 11 and the second profile 12 are different (refer to Figure 9 and Figure 10 ), that is, the first profile 11 and the second profile 12 are different profiles, and the upper crossbeam 3A and the lower crossbeam 3B are perpendicular to the first profile 11 and the second profile 12. The first connector 41 abuts against the first profile 11 and the second profile 12 and is fixedly connected to the first profile 11 and / or the second profile 12. This ensures that the first connector 41 is securely positioned relative to the first profile 11 and the second profile 12 and prevents displacement, thereby ensuring the structural stability of the cabinet.
[0053] More specifically, at least two side surfaces of the first connector 41 abut against the first profile 11. The first connector 41 includes a main body 411 and a contact head 412 extending from the main body 411. The contact head 412 is parallel to the main body 411 and has a ridge protruding from the side surface of the main body 411. The ridge can limit the position of the second profile 12. One side surface of the contact head 412 and one side surface of the main body 411 both abut against the first profile 11, and the bottom surfaces of both the contact head 412 and the main body 411 abut against the second profile 12, thereby ensuring that the first connector 41 is positioned firmly on the first and second profiles 11 and 12.
[0054] The second connecting member 42 has at least two outer surfaces that abut against the crossbeam to ensure that the position of the second connecting member 42 on the crossbeam is determined. In this embodiment, both the upper crossbeam 3A and the lower crossbeam 3B are provided with a slot 30, and the second connecting member 42 is provided with a positioning protrusion 421, which is stuck in the slot 30. The positioning protrusion 421 matches the slot 30, which facilitates the determination of the position of the second connecting member 42 on the upper crossbeam 3A or the lower crossbeam 3B.
[0055] Optimally, the first connecting member 41 and the second connecting member 42 of this embodiment are connected by a connecting bolt 43. In other words, the corner connector of this embodiment preferably also includes a connecting bolt 43. A through hole 410 is defined in the first connecting member 41, and a threaded hole 420 corresponding to the through hole 410 is defined in the second connecting member 42. The connecting bolt 43 passes through the through hole 410 and is threadedly engaged with the threaded hole 420, thereby connecting the first connecting member 41 and the second connecting member 42.
[0056] Furthermore, the second connecting member 42 at one end of the crossbeam is located inside the first side frame 1, and the second connecting member 42 at the other end of the crossbeam is located inside the second side frame 2. Both the first side frame 1 and the second side frame 2 are provided with bolt holes 120 corresponding to the connecting bolts 43. The outer dimensions of the bolt holes 120 are larger than the bolt heads of the connecting bolts 43 to facilitate the passage of the connecting bolts 43. During assembly, the connecting bolts 43 are inserted from the outside along the bolt holes 120, pass through the through holes 410, and are then threaded into the threaded holes 420.
[0057] like Figure 2 as well as Figure 7-12 As shown, the multiple crossbeams of this embodiment include two upper crossbeams 3A and two lower crossbeams 3B. The multiple corner connecting joints include upper corner connecting joints 4A and lower corner connecting joints 4B. The two ends of the upper crossbeam 3A are fixedly connected to the top of the first side frame 1 and the second side frame 2 via an upper corner connecting joint 4A. The two ends of the lower crossbeam 3B are fixedly connected to the bottom of the first side frame 1 and the second side frame 2 via a lower corner connecting joint 4B. The lower crossbeam 3B and the upper crossbeam 3A are configured as the third profile and the fourth profile, respectively, and the cross-sections of the third profile and the fourth profile are different. The first connecting member 41 of the upper corner connecting joint 4A and the first connecting member 41 of the lower corner connecting joint 4B have the same structure, ensuring that the number of parts is as small as possible. The second connecting member 42 of the upper corner connecting joint 4A is different from the second connecting member 42 of the lower corner connecting joint 4B in structure. Due to the difference in the cross-sections of the third profile and the fourth profile, the second connecting member 42 of the upper corner connecting joint 4A and the lower corner connecting joint 4B have different structures. The upper corner connecting joint 4A has another type of second connecting member 42'.
[0058] In this solution, the cabinet body is easy to assemble, which can improve the customer's assembly efficiency, and the overall structure is simple and low-cost.
