Description

Technical Field

[0001] This utility model relates to the field of refrigerator cabinet technology, and in particular to a refrigerator cabinet splicing structure. Background Technology

[0002] A freezer is an electrical appliance used for refrigerating and freezing food. It is commonly used in homes, supermarkets, and restaurants. The main function of a freezer is to maintain a low-temperature environment to extend the shelf life of food and prevent bacterial growth. With the increasing demand for food refrigeration and freezing, the design and manufacturing technology of freezers, as important household and commercial appliances, has also developed rapidly. Traditional freezer cabinets are usually manufactured using a one-piece molding method. Although this design is structurally more stable, the space is relatively limited. Therefore, a freezer cabinet splicing structure is needed.

[0003] Traditional freezers typically employ a one-piece design. While this design is simple in appearance, it has some significant drawbacks in terms of functionality and practicality, especially when storing large quantities of food. Because one-piece freezers often have fixed dimensions and shapes, they cannot be flexibly adjusted according to the user's actual needs. This limits their storage capacity, leaving users facing insufficient space when storing large amounts of food. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a refrigerant cabinet assembly structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A refrigerator cabinet assembly structure includes an equipment box, a base cabinet fixed to the top of the equipment box, an assembly cabinet on top of the base cabinet, and a top cabinet on top of the assembly cabinet. Cabinet doors are installed on the outer walls of the base cabinet, assembly cabinet, and top cabinet. Second connecting plates are fixed to the inner walls of the base cabinet and assembly cabinet near the top. Multiple second through slots are linearly and equidistantly formed on the tops of the two second connecting plates. First connecting plates are fixed to the inner walls of the equipment box and top cabinet near the bottom. Multiple first through slots are linearly and equidistantly formed on the tops of the two first connecting plates, with each of the first through slots corresponding to a second through slot. The bottom of each cabinet is equipped with a sealing mechanism, and the top of the base cabinet and the modular cabinet are equipped with fixing mechanisms for securing the base cabinet, modular cabinet, and top cabinet. Two sets of locking mechanisms for engaging the base cabinet, modular cabinet, and top cabinet are respectively installed at one end of the outer wall of each modular cabinet and top cabinet. During use, this device, through the design of the two fixing mechanisms, allows the base cabinet, modular cabinet, and top cabinet to be joined together, enabling flexible adjustment of the refrigerator's volume. It can be increased or decreased according to actual needs to meet different storage requirements. The two sealing mechanisms effectively seal the gaps at the joints of the base cabinet, modular cabinet, and top cabinet, preventing cold air leakage, ensuring refrigeration effect, and improving the safety of food storage.

[0007] Preferably, the two fixing mechanisms include four T-shaped plates, which are fixed in pairs to the top ends of the base cabinet and the splicing cabinet. T-shaped slots are provided at both ends of the bottom of the splicing cabinet and the top cabinet, and the four T-shaped plates are adapted to the four T-shaped slots respectively. The four T-shaped slots and the four T-shaped plates are fixed together by snap-fitting to ensure their stability and consistency during use.

[0008] Preferably, one set of the snap-fit ​​mechanism includes two first U-shaped plates, which are respectively fixed to symmetrical sides of the outer wall of the splicing cabinet. Connecting seats are slidably connected to the inner sidewalls of both first U-shaped plates. Second U-shaped plates are fixed to symmetrical sides of the outer wall of the base cabinet, and each second U-shaped plate is adapted to one of the two connecting seats. Rectangular grooves are formed on the outer sidewalls of both connecting seats, and both rectangular grooves have a constricted opening structure. Rectangular sliders are slidably connected to the inner sidewalls of both rectangular grooves. Locking blocks are fixed to the outer sidewalls of both rectangular sliders. Springs are installed inside each of the two rectangular grooves. One end of each spring is fixed to one of the two connecting seats, and the other end of each spring is fixed to one of the two rectangular sliders. The base cabinet and the splicing cabinet... After the top cabinet is assembled, press the four locking blocks to move the four rectangular sliders along the inner walls of the four rectangular slides, compressing the four springs. This pushes the four connecting seats downwards along the inner walls of the four first circular plates, so that the bottom ends of the four connecting seats enter the interior of the four second circular plates until the upper eaves of the rectangular slides and the lower eaves of the second circular plates are flush. Release the four locking blocks, and under the reaction force of the four compressed springs, push the four locking blocks out of the four rectangular slides. At this point, the bottom cabinet, the assembled cabinet, and the top cabinet are connected as a single unit, preventing misalignment. By reversing the operation, the bottom cabinet, the assembled cabinet, and the top cabinet can be disassembled into independent units for easy transportation and maintenance.

[0009] Preferably, the sealing mechanism includes a U-shaped sealing strip, which is fixed to the bottom of one of the first connecting plates. A U-shaped groove is provided on the top of one of the second connecting plates near the edge. The U-shaped groove and the U-shaped sealing strip are compatible. After the bottom cabinet, the splicing cabinet and the top cabinet are spliced, the two first connecting plates and the two second connecting plates are in a close fit. That is, the two U-shaped sealing strips are inserted into the two U-shaped grooves respectively, sealing the gaps at the splicing points of the bottom cabinet, the splicing cabinet and the top cabinet to prevent cold air leakage and affect food storage.

[0010] Preferably, the equipment box has air inlets on both symmetrical outer side walls. The air inlets provide a channel for air circulation in the freezer, ensuring effective circulation of cold air inside the cabinet and improving the refrigeration effect.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, this device, through the design of two fixing mechanisms, can connect the bottom cabinet, the modular cabinet and the top cabinet, and can flexibly adjust the volume of the refrigerator to increase or decrease according to actual needs to meet different storage requirements.

[0013] 2. The design of two sealing mechanisms effectively seals the gaps at the joints of the bottom cabinet, the connecting cabinet, and the top cabinet, preventing cold air leakage, ensuring refrigeration effect, and improving the safety of food storage.

[0014] 3. The design of four interlocking mechanisms makes the structure of the bottom cabinet, the assembled cabinet and the top cabinet more stable after assembly, avoiding misalignment between the cabinets and ensuring the integrity and stability of the freezer during use.
