Abstract
Description
Technical Field
[0001] This utility model relates to the field of commercial refrigerator technology, specifically a dual-axis hinge assembly for commercial refrigerators. Background Technology
[0002] Commercial refrigerators are primarily used in commercial settings such as supermarkets, convenience stores, restaurants, hotels, and food processing plants to provide refrigerated or frozen storage environments for food, beverages, and other goods. In supermarkets, commercial refrigerated display cases are used to showcase various fresh foods, dairy products, and beverages, facilitating customer selection while maintaining product freshness. In restaurant kitchens, commercial refrigerators are used to store ingredients, ensuring their quality before cooking.
[0003] Commercial refrigerators typically use stainless steel or high-quality cold-rolled steel sheets for their outer casings. Stainless steel casings offer excellent corrosion resistance, protecting against moisture, grease, and various cleaning agents found in kitchen environments. They are rust-resistant, ensuring the refrigerator remains aesthetically pleasing and durable for a long time. For example, in the humid and greasy environment of a restaurant kitchen, a stainless steel casing effectively prevents damage to the outer shell, extending its lifespan to 10-15 years. Cold-rolled steel sheet casings are relatively cheaper, but require proper surface treatment (such as painting) to enhance their rust resistance.
[0004] Regarding the existing related technologies, the inventor believes that the following defects exist: Existing commercial refrigerator doors generally use single-axis hinges, but frequent opening and swinging of the door or uneven force can cause the single-axis hinges to loosen or be damaged. Utility Model Content
[0005] To address the technical problem of frequent opening and swinging or uneven force on the doors of existing commercial refrigerators, which can lead to loosening or damage of single-axis hinges, this utility model provides a dual-axis hinge assembly for commercial refrigerators.
[0006] This utility model is achieved using the following technical solution: a dual-axis hinge assembly for a commercial refrigerator, comprising a dual-axis hinge and a bushing, wherein the bottom of the dual-axis hinge is hingedly connected to the top of the bushing, the bottom of the bushing is fixedly connected to the upper right door shell, the inner side of the upper right door shell is provided with a right side panel of the refrigerator body, one side of the right side panel of the refrigerator body is fixedly connected to an upper horizontal frame plate, and one side of the dual-axis hinge is fixedly connected to the outside of the right side panel of the refrigerator body and the upper horizontal frame plate.
[0007] Preferably, the right side panel and the upper horizontal frame panel of the box are perpendicular to each other.
[0008] Preferably, a pre-embedded part is provided inside the upper right door shell.
[0009] Preferably, the dual-axis hinge has two shafts inside, and the two shafts slide within the track.
[0010] Preferably, the dual-axis hinge is fixed to the right side plate and the upper horizontal frame plate of the housing through three hinge holes.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In use, this utility model is fixedly installed on the upper right door shell by a bushing. The dual-axis hinge is fixed to the right side plate and the upper horizontal frame plate of the box body through three hinge holes. There are embedded parts inside the upper right door shell to strengthen the hinge assembly. The two shafts of the dual-axis hinge slide in the track. The two shafts of the dual-axis hinge can share the weight of the door body, making the force on the door more even during the opening and closing process, reducing the single point pressure of the door body on the hinge, thereby reducing the risk of hinge damage and helping to extend the service life of the hinge assembly and the door body.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] Example 1: Please refer to Figure 1 - Figure 5This embodiment of a dual-axis hinge assembly for a commercial refrigerator includes a dual-axis hinge 1 and a bushing 2. The bottom of the dual-axis hinge 1 is hinged to the top of the bushing 2. The bottom of the bushing 2 is fixedly connected to the upper right door shell 5. The inner side of the upper right door shell 5 is provided with a right side panel 3. One side of the right side panel 3 is fixedly connected to an upper horizontal frame plate 4. The right side panel 3 and the upper horizontal frame plate 4 are perpendicular to each other. The dual-axis hinge 1 is fixed to the right side panel 3 and the upper horizontal frame plate 4 through three hinge holes.
[0021] In this invention, the existing dual-axis hinge 1 is used to achieve the purpose of embedding in the commercial refrigerator. The bushing 2 is fixedly installed on the upper right door shell 5. There are embedded parts inside the upper right door shell 5 to strengthen the hinge assembly. The two shafts of the dual-axis hinge 1 slide in the track. The hinges used in the upper left and lower right of the commercial refrigerator are the same type, and the hinges used in the upper right and lower left are the same type, which are single-sided hinges. The middle hinge is a double-sided hinge, which acts on the same side of the door. The dual-axis hinge 1 is fixed to the side plate of the cabinet and the horizontal frame plate through three hinge holes.
[0022] Secondly, the dual-axis hinge assembly has two rotation axes. The design of these two axes allows the commercial refrigerator door to open and close in a more complex and flexible way. One axis is usually close to the main frame of the refrigerator, while the other axis is closer to the edge of the door. When the door is opened, the axis closer to the main frame starts to rotate first, creating a certain gap between the door and the refrigerator body. Then the axis closer to the edge of the door rotates, allowing the door to open smoothly outward. This dual-axis linkage method can effectively prevent the door from colliding with surrounding objects during the opening process.
[0023] Dual-axis hinge assemblies provide a more robust support structure for commercial refrigerator doors. In commercial environments where doors are frequently opened and closed, the two axes of the dual-axis hinge 1 can distribute the weight of the door, making the force on the door more even during opening and closing. When customers forcefully open or close the glass door of a supermarket refrigerated display case, the dual-axis hinge can effectively disperse the impact force, reduce the single-point pressure of the door on the hinge, thereby reducing the risk of hinge damage and helping to extend the service life of the hinge assembly and the door.
[0024] Working principle: The hinge is fixedly installed on the upper right door shell 5 through the bushing 2. The double-axis hinge 1 is fixed to the right side plate 3 and the upper horizontal frame plate 4 of the box body through three hinge holes. There are embedded parts inside the upper right door shell 5 to strengthen the hinge assembly. The two shafts of the double-axis hinge 1 slide in the track. The two shafts of the double-axis hinge 1 can distribute the weight of the door body, making the force on the door more even during the opening and closing process, reducing the single point pressure of the door body on the hinge, thereby reducing the risk of hinge damage and helping to extend the service life of the hinge assembly and the door body.
[0025] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
