Description

A refrigerator box structure

technical field

The utility model relates to the technical field of refrigerators, in particular to a novel refrigerator box assembly structure.

Background technique

At present, the casing of a refrigerator is usually composed of left and right side panels, a top panel, a rear panel, and an inner container. One of the structures is that the side plates and the top plate are integrated. This structure is relatively bulky and inconvenient for processing, turnover and storage. Another structure is that the left side panel, the top panel, and the right side panel are split.

Wherein, the roof of the split structure is further divided into two types: a plastic roof (as shown in Figure 1) and a metal roof (as shown in Figure 2). The production of the current metal top plate needs to go through multiple processes such as rolling and stamping to form complex hemming structures, reinforcing ribs, and screw holes. The process is complicated and cumbersome, the production efficiency is low, and the cost is high; Screws are used for connection, and the screw heads are exposed, causing the top surface of the refrigerator to be uneven. Another one, such as the Chinese patent ZL200720053647.6, discloses a refrigerator top plate structure, including a top plate and an upper door hinge core connecting the top plate to the door body. Nuts are embedded in the top plate, and the upper door hinge core is connected to the top plate by threads. Connected to the door body, the nuts are inlaid in the top plate through injection molding together with the top plate; the specific production process is to inlay the above nuts into the top plate during injection molding, and the upper door hinge core and the nut are threaded to form a top plate structure, and then Assembled on the refrigerator box; the top plate is not strong enough due to the injection molded parts, which is prone to scratches, cracks and other problems. Both of the above two top plates need to be fixed to the box body with several screws, and the common disadvantage is that the assembly method is complicated and the cost is relatively high.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a refrigerator with convenient processing, easy installation, low cost, small and uniform connection gap, and a smooth top surface by improving the matching structure of the refrigerator top plate and the refrigerator side plate. Refrigerator box structure.

The technical scheme for solving the technical problems of the utility model is: a refrigerator box structure, including a top board, a left side board, a right side board, an inner tank, and a rear board, and it is characterized in that: the top board of the refrigerator box is connected to the left, The right board is clamped and connected; the back board of the refrigerator box is plugged and connected with the left and right side boards and the top board; the liner of the refrigerator box is embedded and connected with the left and right side boards and the top board.

The longitudinal connecting edges of the top plate and the left and right side plates are respectively provided with buckles and slots; the buckles and slots are arranged along the length of the entire longitudinal connecting side; the width of the slots is slightly smaller than that of the card The outer width of the buckle; the buckle is inserted into the card slot, and the card slot and the buckle are an interference fit to ensure that the gap between the top plate and the side plate is small and uniform and prevent the top plate from loosening after assembly.

The front joints of the top board and the left and right side boards are overlapped with beveled edges, and the fronts are flattened and evenly spaced.

There are slots at the connecting edges of the left and right side panels and the top panel and the rear panel, and the rear panel is provided with folded edges; the folded edges of the rear panel are respectively inserted into the slots of the left, right side panels and the top panel; The slots on the right and top panels are identical in structure and size.

The connecting edges of the left and right side plates and the top plate and the liner are provided with slots; the three sides of the liner are respectively embedded in the slots of the left and right side plates and the top plate; Grooves, which have the same structure and dimensions.

In this way, the slots and slots of the top plate and the slots and slots of the left and right side plates can be integrally rolled and formed, thereby simplifying the processing technology of the top plate.

The top plate of the refrigerator box in the utility model can be integrally rolled and formed with the side plate. Compared with the prior art, the utility model simplifies the processing technology of the top plate, saves the screwing process in the installation process, has simple assembly process, small and uniform connection gap, flat top surface, low cost and good practicability.

Detailed ways

Referring to accompanying drawing 3, Fig. 4, Fig. 5, Fig. 6, the cabinet structure of the utility model refrigerator comprises top plate 1, left side plate 2, right side plate 3, liner 4 and rear plate 5.

As shown in FIG. 4 , buckles 1 a are provided on the left and right sides of the top board 1 ; slots 3 a are respectively provided on the upper parts of the left side board 2 and the right side board 3 . The top plate 1 is connected together by snapping into the slots 3a of the left and right side plates through buckles 1a, forming the top assembly of the box body. The structural form of buckle 1a and card slot 3a is convenient for insertion during card assembly and is not easy to come out after assembly. The card slot buckle shown in the figure is one of the forms. The inner width of the slot 3a is slightly smaller than the outer width of the buckle 1a; the slot and the buckle are an interference fit, and the buckle can be easily inserted into the slot under appropriate external pressure. Under the action, it can ensure that the gap between the top plate and the side plate is small and uniform, and can prevent the possible loosening of the top plate after assembly.

As shown in accompanying drawing 5, Fig. 6, the top edge and left and right sides of back plate 5 are respectively provided with flanging 5a, and the rear portion of left side plate 2, right side plate 3 is respectively provided with slot 3b, and the rear portion of top plate 1 Slot 1b is provided. The rear plate is inserted into the slot 3b of the side plate and the slot 1b of the top plate respectively through its flange 5a, and is connected together with the side plate and the top plate to form the rear assembly of the box body.

As shown in accompanying drawings 5 and 6, the front part of the top board 1 is provided with a slot 1c, and the front parts of the left side board 2 and the right side board 3 are respectively provided with a slot 3c. The top edge and the left and right sides of the liner 4 are respectively embedded in the caulking groove 1c of the top plate and the caulking groove 3c of the left and right side plates to form the front assembly of the box body.

The slot 1b of the top plate and the slot 3b of the side plate have the same structure and size; the slot 1c of the top plate and the slot 3c of the side plate have the same structure and size; cost.
