Technical Field
[0001] This utility model belongs to the technical field of commercial refrigerators, specifically, it relates to a magnetic central column for a refrigeration cabinet. Background Technology
[0002] A refrigerator is a refrigeration device that maintains a constant low temperature; it's also a consumer product used to keep food or other items at a constant low temperature. Commercial refrigerators are refrigeration devices specifically designed for commercial settings, primarily used for storing food, beverages, and other goods, and are commonly found in supermarkets, restaurants, and hotels. Their core features include large capacity, professional temperature control, and display functions, which significantly differ from household refrigerators. Side-by-side commercial refrigerators typically have a central support column in the middle of the refrigerator to work with the door to maintain a closed, sealed state. While this column meets the sealing requirements of commercial refrigerators, its placement inside the refrigerator occupies internal space and can easily interfere with the loading and unloading of items, presenting certain drawbacks in practical use.
[0003] In view of this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a magnetic central column for a refrigeration cabinet. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: A magnetic center column for a refrigeration cabinet includes an outer shell and a fixed mounting back plate. One end of the outer shell has a first mounting plug, and the other end has a second mounting plug. Mounting connectors are correspondingly provided on the inner sides of both mounting plugs. Connecting ends one and two are respectively inserted into the mounting connectors at both ends, with connecting end one located at one end of mounting plug one and connecting end two located at one end of mounting plug two. The outer shell has an insertion cavity, where a magnetic strip is inserted. One end of the magnetic strip is a rectangular frame structure, and the other end has two mating forks located within the insertion cavity. A mating stainless steel piece is fitted into the insertion cavity of the outer shell, positioned between the two mating forks of the magnetic strip. The fixed mounting back plate has fixed mounting holes and through holes.
[0005] As a further embodiment of this utility model: the fixed mounting hole is an elongated oval hole structure, the through hole is a round hole structure, and the mounting connector, the first connecting end, and the second connecting end are all provided with fixed mounting holes and through holes respectively. The fixed mounting hole facilitates the fixed connection between the fixed mounting back plate and the refrigerator door, and the through hole facilitates the threading of wires.
[0006] As a further embodiment of this utility model: the rectangular frame structure of the magnetic suction strip is equipped with sealing plugs at both ends, the plug end of the sealing plug is provided with a plug body, the plug body is provided with plug bevels on both sides, and the size of the plug body is adapted to the inner wall size of the rectangular frame structure, so as to not only enable effective plug-in installation, but also maintain good sealing performance and enhance dust protection effect.
[0007] As a further embodiment of this utility model: a connecting buckle is provided at the end of the outer shell away from the mating stainless steel, and a connecting block is provided on the mounting connector. The position and specifications of the connecting buckle correspond to the position and specifications of the connecting block. A snap-fit groove is provided on the side of the outer shell located on the mating stainless steel, and a snap-fit claw is provided on the mounting connector. The position, shape, and specifications of the snap-fit groove are adapted to the position, shape, and specifications of the snap-fit claw, thereby achieving an effective mating connection between the outer shell and the mounting connector.
[0008] As a further embodiment of this utility model: a mating block is provided on the back of the mating stainless steel on the outer shell, and two mating blocks are provided, which are located on both sides of the mating stainless steel. A mating groove is provided on the mounting connector, and the position and specifications of the mating groove correspond to those of the mating block, so as to effectively limit the mating between the outer shell and the mounting connector.
[0009] As a further improvement of this utility model: the middle plate of the fixed mounting back plate is provided with a plug-in mating groove, and the lower part of the mounting connector is provided with a connecting strip. The connecting strip and the plug-in mating groove cooperate with each other to realize the effective connection between the mounting connector and the fixed mounting back plate.
[0010] As a further improvement of this utility model: the first connecting end and the second connecting end are plugged into each other with the mounting connector, and the shape and specifications of the connecting end are adapted to the shape and specifications of the mounting plug and the mounting connector to ensure effective connection.
[0011] As a further embodiment of this utility model: the outer shell and the fixed mounting back plate are hollow structures with open ends, and the fixed mounting back plate is fixedly connected to the refrigerator door.
[0012] A method for using magnetic center posts in a refrigerator: When the refrigerator door is open, a stainless steel insert and a magnetic strip are attracted to each other. The magnetic strip is located near the inner side of the insertion cavity. When the two opposing refrigerator doors are closed, the two magnetic center posts on the refrigerator doors move closer together. The magnetic force of the magnetic strips on the two center posts is greater than the magnetic force between the magnetic strip and the stainless steel insert. As the two magnetic strips move closer, they gradually overcome the magnetic force between the magnetic strip and the stainless steel insert, causing the magnetic strips to move away from the stainless steel insert. The two magnetic strips then come into contact and seal the two refrigerator doors. When the refrigerator door is opened, as the distance between the two magnetic strips increases, the magnetic force between the two magnetic strips gradually decreases until the magnetic force between the two magnetic strips is less than the magnetic force between the magnetic strip and the matching stainless steel. Under the magnetic attraction between the matching stainless steel and the magnetic strip, the magnetic strip is attracted to the matching stainless steel, realizing the automatic magnetic rebound of the magnetic strip on the central column. The side-by-side refrigerator features two sets of automatically retractable magnetic center columns, eliminating the need for an internal center column inside the refrigerator. This effectively expands the internal space, making it easier to access items. The center column has a hollow cavity structure, making it lightweight. The components are fixed together by plugging and snapping, facilitating assembly, disassembly, repair, and replacement.
[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.
[0014] The magnetic central column of this utility model features a modular structure design, facilitating assembly and disassembly. The specific structure includes an outer shell, a fixed mounting back plate, a mounting connector, and a magnetic strip. A magnetic strip is inserted into the outer shell, and a matching stainless steel piece is fitted at the insertion cavity of the outer shell. In its natural state, the matching stainless steel piece attracts the magnetic strip, which is located near the inner side of the insertion cavity. When the two opposing refrigerator doors are closed, the two magnetic central columns on the refrigerator doors move closer together. The magnetic force of the magnetic strips on the two central columns is greater than the magnetic force between the magnetic strip and the matching stainless steel piece, causing the magnetic strip to move away from the matching stainless steel piece. The two magnetic strips then come into contact, sealing the two refrigerator doors. When the refrigerator doors are opened, the magnetic force between the two magnetic strips gradually decreases. Under the magnetic attraction of the matching stainless steel piece and the magnetic strip, the magnetic strip adheres to the matching stainless steel piece, achieving automatic springback.
[0015] This utility model, through the setting of two sets of automatically rebounding magnetic central columns, eliminates the need for an internal central column inside the refrigerator, effectively expanding the internal space of the refrigerator and facilitating the loading and unloading of items. The central column has an overall hollow cavity structure, making it lightweight. The components are fixed by plugging and snapping, facilitating assembly and disassembly.

[0023] The rectangular frame structure of the magnetic suction strip 8 is equipped with sealing plugs 9 at both ends. The plug end of the sealing plug 9 is equipped with a plug body 15. The plug body 15 has plug bevels on both sides. The size of the plug body 15 is adapted to the inner wall size of the rectangular frame structure, which can not only make effective plug-in installation, but also maintain good sealing performance and enhance dust protection effect.
[0024] A connecting buckle 12 is provided at the end of the outer shell 1 away from the mating stainless steel 14, and a connecting block 13 is provided on the mounting connector 7. The position and specifications of the connecting buckle 12 correspond to the position and specifications of the connecting block 13. A snap-fit groove 20 is provided on the side of the outer shell 1 located on the mating stainless steel 14, and a snap-fit claw 21 is provided on the mounting connector 7. The position, shape and specifications of the snap-fit groove 20 are adapted to the position, shape and specifications of the snap-fit claw 21, so as to achieve effective mating connection between the outer shell 1 and the mounting connector 7.
[0025] The outer shell 1 is provided with a mating block 17 on the back of the mating stainless steel 14. There are two mating blocks 17, which are located on both sides of the mating stainless steel 14. The mounting connector 7 is provided with a mating groove 16. The position and specifications of the mating groove 16 and the mating block 17 correspond to each other, effectively limiting the mating between the outer shell 1 and the mounting connector 7.
[0026] The middle plate of the fixed mounting back plate 6 is provided with a plug-in mating groove 18, and the lower part of the mounting connector 7 is provided with a connecting strip 19. The connecting strip 19 and the plug-in mating groove 18 cooperate with each other to realize the effective connection between the mounting connector 7 and the fixed mounting back plate 6.
[0027] The first connecting end 3 and the second connecting end 5 are inserted into the mounting connector 7. The shape and specifications of the connecting ends are adapted to the shape and specifications of the mounting plug and the mounting connector 7 to ensure an effective connection.
[0028] The outer shell 1 and the fixed mounting back plate 6 are hollow structures with open ends, and the fixed mounting back plate 6 is fixedly connected to the refrigerator door.
[0029] The working principle of this utility model is as follows: Example 1: The magnetic center column features a modular design with plug-in and snap-fit connections for easy assembly and disassembly. The specific structure includes an outer shell 1, a fixed mounting back plate 6, a mounting connector 7, and a magnetic strip 8. The outer shell 1 has a plug-in cavity into which the magnetic strip 8 is plugged and installed. A matching stainless steel iron 14 is fitted at the plug-in cavity of the outer shell 1. In its natural state (refrigerator door open), the matching stainless steel iron 14 attracts the magnetic strip 8, which is located near the inner side of the plug-in cavity (as shown in the attached diagram). Figure 8 As shown in the attached diagram, when the two refrigerator doors are closed, the two magnetic posts on the refrigerator doors move closer together. The magnetic force of the magnetic strips 8 on the two magnetic posts is greater than the magnetic force between the magnetic strips 8 and the mating stainless steel 14. As the two magnetic strips 8 move closer together, they gradually overcome the magnetic force between the magnetic strips 8 and the mating stainless steel 14. The magnetic strips 8 then move away from the mating stainless steel 14, and the two magnetic strips 8 come into contact, sealing the two refrigerator doors together (as shown in the attached diagram). Figure 9As shown in the figure, when the refrigerator door is opened, as the distance between the two magnetic strips 8 increases, the magnetic force between the two magnetic strips 8 gradually decreases until the magnetic force between the two magnetic strips 8 is less than the magnetic force between the magnetic strip 8 and the matching stainless steel 14. Under the magnetic attraction of the matching stainless steel 14 and the magnetic strip 8, the magnetic strip 8 is attracted to the matching stainless steel 14, realizing the automatic magnetic rebound of the magnetic strip 8 on the central column; The side-by-side refrigerator features two sets of automatically retractable magnetic central columns, eliminating the need for an internal central column inside the refrigerator. This effectively expands the internal space, making it easier to access items. The central column has a hollow cavity structure, making it lightweight. The components are fixed together by plugging and snapping, facilitating assembly, disassembly, repair, and replacement. Example 2: Based on the above examples, since the main body of the magnetic central column is a hollow structure and a through hole 11 is provided on one side of the mounting surface of the fixed back plate, an electric heating wire (not shown in the attached figure) can be added inside the hollow structure of the magnetic central column. The electric heating wire can heat the inside of the magnetic central column, preventing the central column from freezing at low temperatures and affecting the performance. The specifications, installation, circuit connection and working principle of the electric heating wire are all existing technologies and will not be described in detail here. The use of the magnetic central column structure eliminates the need for a central column structure inside the refrigerator, increasing the opening of the refrigerator frame and making it easier to put in and take out items. This magnetic central column structure can also be applied to other side-by-side products such as cabinets. The magnetic central column of this utility model features a modular structure design, facilitating assembly and disassembly. The specific structure includes an outer shell 1, a fixed mounting back plate 6, a mounting connector 7, and a magnetic strip 8. The magnetic strip 8 is inserted into the outer shell 1, and a matching stainless steel iron 14 is fitted at the insertion cavity of the outer shell 1. In its natural state, the matching stainless steel iron 14 and the magnetic strip 8 are attracted to each other, with the magnetic strip 8 located near the inner side of the insertion cavity. When the two opposing refrigerator doors are closed, the two magnetic central columns on the refrigerator doors move closer together. The magnetic force of the magnetic strip 8 on the two magnetic central columns is greater than the magnetic force between the magnetic strip 8 and the matching stainless steel iron 14, resulting in magnetic attraction. When the magnetic strip 8 separates from the stainless steel 14, the two magnetic strips 8 come into contact and seal the two refrigerator doors. When the refrigerator door is opened, the magnetic force between the two magnetic strips 8 gradually decreases. Under the magnetic attraction of the stainless steel 14 and the magnetic strips 8, the magnetic strips 8 are attracted to the stainless steel 14 and automatically spring back. This utility model, through the setting of two sets of automatically spring-back magnetic central columns, eliminates the need for an internal central column in the refrigerator, effectively expanding the internal space of the refrigerator and facilitating the loading and unloading of items. The central column has a hollow cavity structure, making it lightweight. The assembled components are fixed by plugging and snapping, facilitating assembly and disassembly.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
