Description

Technical Field

[0001] This utility model relates to the field of freezer technology, specifically to a freezer with an invisible frame and plug-in structure. Background Technology

[0002] A freezer is a device used to store and preserve food at low temperatures. There are two types: household and commercial. Commercial freezers are used in restaurants, bars, food processing plants, and supermarkets. The outer shell is the top layer of the freezer and serves as a decorative element.

[0003] In the process of developing this utility model, the inventor discovered the following problems with the existing technology: 1. The existing refrigerator shell insertion method is a shell insertion frame structure, and the outer edge of the frame needs to retain a thin wall. This insertion structure is prone to defects such as frame jamming, top whitening, and top damage during assembly, and affects the overall integrity and aesthetics of the refrigerator, thus failing to meet people's usage needs; 2. During use, the existing refrigerator shell is mostly fixed by magnetic attraction. When the refrigerator is shaken significantly during transportation, the shell and the refrigerator body are prone to separation. In addition, the traditional shell is made of metal, while the frame is made of plastic. Due to the different heat shrinkage ratios, poor fit and gaps are prone to occur in winter and summer, which greatly reduces the stability of the shell during use and greatly reduces the practicality of the refrigerator. Utility Model Content

[0004] The purpose of this utility model is to provide a refrigerator with an invisible frame and plug-in structure, in order to solve the problems mentioned in the background art. The existing refrigerator shell plug-in method is a shell insertion frame structure, which requires the outer edge of the frame to retain a thin wall. This plug-in structure is prone to defects such as frame jamming, top whitening, and top damage during assembly, and affects the overall integrity and aesthetics of the refrigerator. In addition, most existing refrigerator shells are simply fixed with magnetic attraction during use. When the refrigerator is shaken significantly during transportation, the shell and the refrigerator body are prone to separation, which greatly reduces the stability of the shell during use. To achieve the above objectives, this utility model provides the following technical solution: a concealed frame box shell plug-in structure freezer, including an outer shell assembly, with two cavities opened on one side of the inner side of the outer shell assembly, and sliding grooves opened on the inner walls of the two cavities. The inner middle of one end of each of the two cavities is connected to one end of a spring, and pressure plates are provided at the other ends of the two springs. Slider blocks are provided at both ends of the two pressure plates, and locking pins are provided on the side of the two pressure plates away from the springs. A box cover is provided at the top of one side of the outer shell assembly, and three second magnetic stones are respectively provided on the outer sides of the bottom end of the box cover. An annular sealing frame is provided at the middle of the bottom end of the box cover, and a sealing gasket is provided at the bottom end of the annular sealing frame. Two slots are opened on one side of the annular sealing frame. The outer shell assembly includes a freezer body, and three first magnetic stones are respectively provided on the outer sides of the top end of the freezer body. A slot is opened at the middle of the top end of the freezer body.

[0005] More preferably, the internal dimensions of the cavity are the same as the external dimensions of the pressure plate.

[0006] More preferably, the groove and the slider are configured to slide together.

[0007] More preferably, the sealing gasket is made of rubber and is designed as a retractable structure.

[0008] More preferably, the locking pin and spring are symmetrical about the vertical center line of the freezer body.

[0009] More preferably, the slot and the pin are configured as a snap-fit ​​structure.

[0010] According to the foregoing description of this solution, the beneficial technical effects of this utility model include: This technical solution, through the combination of an annular sealing frame, slots, and sealing gaskets, ensures that the appearance of the refrigerator body is consistent, simple, and aesthetically pleasing during use. It solves the problems of frame jamming, whitening, and damage that can easily occur during assembly when the lid and refrigerator body are connected by a plug-in structure, thus meeting the requirements of refrigerators with a concealed frame and plug-in structure.

[0011] This technical solution utilizes the combination of latches, slots, and springs to enhance the fixation of the lid during closure of the concealed frame box-type refrigerator. The latches and slots work together to create a larger clearance between the refrigerator body and the lid, making it less sensitive to changes in winter and summer dimensions. This saves on the cost and time of adjusting materials and dimensions, provides greater tolerance for errors, and significantly increases the stability of the lid during closure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a hidden frame box shell plug-in structure refrigerator, including an outer shell assembly 1. Two cavities 2 are opened on one side of the inner side of the outer shell assembly 1. Sliding grooves 3 are opened on the two inner walls of the two cavities 2. The middle of one end of the inner side of the two cavities 2 is connected to one end of the spring 4. The other end of the two springs 4 is provided with a pressure plate 5. The two ends of the two pressure plates 5 are provided with sliders 6. The side of the two pressure plates 5 away from the springs 4 is provided with a locking pin 7. A box cover 8 is provided at the top of one side of the outer shell assembly 1. Three second magnetic stones 9 are respectively provided on the two outer sides of the bottom end of the box cover 8. An annular sealing frame 10 is provided at the middle of the bottom end of the box cover 8. A sealing gasket 11 is provided at the bottom end of the annular sealing frame 10. Two locking grooves 12 are opened on one side of the annular sealing frame 10.

[0019] like Figure 1 As shown, the outer casing assembly 1 includes a freezer body 101, three first magnetic stones 102 are respectively provided on the top outer sides of the freezer body 101, and a slot 103 is provided in the middle of the top of the freezer body 101.

[0020] like Figure 1 As shown, the internal dimensions of the cavity 2 are consistent with the external dimensions of the pressure plate 5; this ensures that the pressure plate 5 moves in a single direction, preventing it from shifting or tilting during movement, thereby improving the stability of the pressure plate 5 during movement.

[0021] like Figure 3 As shown, the slide groove 3 and the slider 6 are connected by a sliding connection; this increases the stability of the pressure plate 5 during movement, thereby preventing the pressure plate 5 from rotating or tilting during movement.

[0022] like Figure 2 As shown, the sealing gasket 11 is made of rubber and is designed as a retractable structure; it improves the sealing performance of the freezer body 101 and the lid 8, increases the sealing effect of the freezer body 101 during use, makes it less likely for the freezer body 101 to leak during use, eliminates the need for rework, and saves the cost and time of rework due to leakage.

[0023] like Figure 4 As shown, the locking pin 7 and spring 4 are symmetrical about the vertical center line of the freezer body 101 with respect to the pressure plate 5. The cooperation between the locking groove 12 and the locking pin 7 achieves the fixing effect of the lid 8 during the closing process, and provides a larger fitting gap between the freezer body 101 and the lid 8. This makes the lid less sensitive to winter and summer dimensions, saves the cost and time of adjusting materials and dimensions, and has a greater fault tolerance, thereby greatly increasing the stability of the lid 8 during the closing process.

[0024] like Figure 3 As shown, the slot 12 and the pin 7 are designed with a snap-fit ​​structure to increase the stability of the lid 8 during use and prevent the lid 8 from detaching from the main body 101 of the freezer during use.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the freezer body 101 is placed in the designated position. When it is necessary to close the lid 8 of the freezer body 101, the lid 8 is pushed to rotate around the central axis of the hinge. When the lid 8 moves the annular sealing frame 10 into the slot 103, the two locking pins 7 are resisted by the outer wall of the annular sealing frame 10, which will drive the pressure plate 5 to move into the cavity 2 under the cooperation of the slider 6 and the slide groove 3. At the same time, the pressure plate 5 compresses the spring 4. As the annular sealing frame 10 moves downward, when the annular sealing frame... When the frame 10 moves the slot 12 to the pin 7, the spring 4 uses its own elastic structure to drive the pin 7 to engage with the inside of the slot 12 through the pressure plate 5, with the cooperation of the slide 3 and the slider 6. This creates a locking structure between the pin 7 and the slot 12, thereby improving the fixing effect of the lid 8 during closing and providing a larger clearance between the freezer body 101 and the lid 8. This makes the lid less sensitive to winter and summer dimensions, saves the cost and time of adjusting materials and dimensions, and has a greater fault tolerance, thus significantly increasing the stability of the lid 8 during closing.

[0026] The first magnetic stone 102 and the second magnetic stone 9 are also simultaneously attached together. The sealing gasket 11 can improve the sealing performance of the freezer body 101 and the lid 8, increase the sealing effect of the freezer body 101 during use, and avoid leakage caused by inadequate sealing during use. This makes the appearance of the freezer body 101 look consistent, simple and beautiful. It solves the problem that defects such as frame jamming, whitening, and damage are easily caused during assembly due to the plug-in structure between the lid 8 and the freezer body 101. The sealing gasket 11 can greatly increase the sealing effect between the freezer body 101 and the lid 8, making it less likely to leak during use. This eliminates the need for rework and saves the cost and time of rework due to leakage, thus meeting the requirements of the invisible frame box shell plug-in structure freezer.
