[0002] An undercounter refrigerator is a refrigeration device used to store food. It is usually placed under the counter or bar in catering and retail places. Its main function is to ensure the freshness of refrigerated food. On the one hand, the undercounter refrigerator has a constant temperature and strong "freezing power". On the other hand, it needs to keep the air in the refrigerator purified and fresh, which can maintain the freshness and quality of food and beverages. It itself has the advantages of corrosion resistance, easy cleaning and long service life. At the same time, the design of the undercounter refrigerator also needs to pay attention to beauty and elegance, and be able to coordinate with the surrounding environment.
[0003] The door panel of the under-counter refrigerator is an important component thereof, and is usually made of high-quality stainless steel plate, which is corrosion-resistant and easy to clean. The door panel not only has the functions of heat preservation and refrigeration, but also can prevent outside air from entering the interior of the refrigerator. The door panel is generally also equipped with an easy-to-operate handle to facilitate users to open and close it. Usually, the existing door panels of under-counter refrigerators are generally installed on the cabinet body through hinges and other hinged structures, and the door panels can be opened and closed freely. However, the hinged structure of the door panels of the existing under-counter refrigerators often only has a simple opening and closing function, and does not consider how to keep the door panels stable in the open state. The door panels are prone to rebound and reset to a certain extent, which hinders the access of items. At the same time, when closing the door panels, they need to be manually pushed to close, which is more laborious and difficult to grasp the pushing force. Excessive force can easily cause damage to the door panel connection structure.
[0004] Therefore, it is necessary to provide a door opening and closing structure of an under-counter refrigerator to solve the above technical problems. Utility Model Content

During the opening and closing of the door panel 2, the opening and closing positions of the door panel 2 are automatically limited by the rotation stop assembly 1, so that the door panel 2 can automatically remain in a stationary state during the opening and closing process after the door panel 2 is opened, so that the opened door panel 2 will not rebound and reset to block people from storing or taking items, thereby improving the convenience of storing and retrieving items. Gently pushing the door panel 2 with a small stroke can make the door panel 2 slowly and automatically reset and close, thereby realizing the self-closing of the door panel 2 to a certain extent, reducing the manpower pushing to close the door panel 2 while also avoiding the problem of easy damage to the door panel 2 caused by excessive force.
[0024] Further as Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, it is worth specifically explaining that the rotation stop assembly 1 includes a second circular plate 102 fixed on the side surface of the first connector column 8, a plurality of second triangular protrusions 105 distributed in an annular manner are fixed on the side surface of the second circular plate 102 close to the second convex plate 7, a first triangular groove 104 is arranged between two adjacent second triangular protrusions 105, a first circular plate 101 is fixed on the side surface of the second convex plate 7 close to the second circular plate 102, a plurality of first triangular protrusions 103 that fit in with the first triangular groove 104 are fixed on the side surface of the first circular plate 101 close to the second circular plate 102, and a second triangular groove 106 that fits in with the second triangular protrusion 105 is arranged between two adjacent first triangular protrusions 103; in the process of opening and closing the door panel 2, the door panel 2 drives the first connector column 8 and the second connector column 10 to rotate on the second convex plate 7 and the first convex plate 4 respectively, and the first connector column 8 synchronously drives the second circular plate 102 to rotate relative to the first circular plate 101, so that the second triangular protrusions 105 on the second circular plate 102 surround the first triangular protrusions 105 on the second circular plate 102. The central axis of a joint column 8 rotates, and the first joint column 8 and the second joint column 10 can slide up and down on the second convex plate 7 and the first convex plate 4 respectively, so that the door panel 2 is pushed to make a certain displacement in the up and down directions through the inclined surface cooperation, so that the second triangular protrusion 105 and the first triangular protrusion 103 are respectively inserted into different second triangular grooves 106 and first triangular grooves 104, thereby automatically limiting the open and closed positions of the door panel 2, so that the door panel 2 can automatically remain in a stationary state after opening, so that the opened door panel 2 will not rebound and reset to block people from storing or taking items, thereby improving the convenience of storing and retrieving items, and by gently pushing the door panel 2 with a small stroke, the second triangular protrusion 105 and the first triangular protrusion 103 respectively slide out of the second triangular groove 106 and the first triangular groove 104 and slide back into engagement, so that the door panel 2 can slowly and automatically reset and close, and to a certain extent realize the self-closing of the door panel 2, while reducing the manpower pushing to close the door panel 2, it also avoids the problem of easy damage to the door panel 2 due to excessive force.
[0025] This solution has the following working process: when the items need to be refrigerated, the door panel 2 is first opened, and the items to be refrigerated are placed into the storage cavity 6 through the opening of the storage cavity 6, and then the door panel 2 is closed, so that the opening of the storage cavity 6 is covered by the door panel 2, so that the items are stored in a closed refrigerated manner. In the process of opening and closing the door panel 2, the door panel 2 drives the first joint column 8 and the second joint column 10 to rotate on the second convex plate 7 and the first convex plate 4 respectively, and the first joint column 8 synchronously drives the second circular plate 102 to rotate relative to the first circular plate 101, so that the second triangular protrusion 105 on the second circular plate 102 rotates around the central axis of the first joint column 8, and the first joint column 8 The second connector column 10 can slide up and down on the second convex plate 7 and the first convex plate 4 respectively, so that the door panel 2 can be displaced in the up and down directions by cooperating with the inclined surface, so that the second triangular protrusion 105 and the first triangular protrusion 103 are respectively inserted into the second triangular groove 106 and the first triangular groove 104 at different positions, thereby automatically limiting the opening and closing positions of the door panel 2, so that the door panel 2 can automatically remain stationary after being opened, and by gently pushing the door panel 2 with a small stroke, the second triangular protrusion 105 and the first triangular protrusion 103 can slide out of the second triangular groove 106 and the first triangular groove 104 respectively and slide back in to engage, so that the door panel 2 can slowly and automatically reset and close.
[0026] Further as Figure 3 , Figure 6 and Figure 7 As shown, it is worth explaining in detail that a first joint plate 9 is fixed to the end of the first joint column 8 away from the door panel 2, and the diameter of the first joint plate 9 is larger than the diameter of the first joint column 8, and a second joint plate 11 is fixed to the end of the second joint column 10 away from the door panel 2, and the diameter of the second joint plate 11 is larger than the diameter of the first joint column 8; during specific operation, the first joint plate 9 and the second joint plate 11 are respectively formed with the second protruding plate 7 and the first protruding plate 4 to form a stop limit cooperation, so that the door panel 2 moves up and down a fixed displacement.
[0027] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a sealing ring 5 located at the opening edge of the storage cavity 6 is fixed on the inner side surface of the door panel 2, and a handle is fixed on the outer side surface of the door panel 2; during specific operation, the sealing ring 5 is provided to improve the sealing performance of the door panel 2 when closing the opening of the storage cavity 6, thereby improving the storage effect.
