[0002] A commercial freezer is a refrigeration or freezing device specifically used for commercial operation channels, mainly used for storing items such as ice cream, beverages, dairy products, frozen foods, food materials, etc. Commercial freezers are generally divided into three categories: commercial refrigerators, also known as beverage cabinets, commercial freezers, also known as cold food cabinets, and kitchen refrigerators. When placing cold chain goods, a shelf structure is required for commercial freezers. The shelf structure of a commercial freezer refers to a shelf used in a commercial refrigeration environment for storing and displaying refrigerated goods.

[0003] After retrieval, a shelf structure of a freezer with the publication number CN210593680U specifically discloses a shelf structure of a freezer, including a shelf main body and several carrier plates. There are several partition plates in the shelf main body to form several shelf cavities. The carrier plates are installed on the shelf cavities, and the carrier plates are installed at a certain inclination angle. An appropriate space is reserved between the carrier plates to store goods. The carrier plate is provided with a limiting mechanism, and the limiting mechanism is arranged at the end of the inclined downward direction. The retraction and extension of the limiting mechanism realize the goods delivery and limiting. The beneficial effect of the utility model is that the carrier plates are inclined and installed on the shelf main body, so that the goods can slide along the carrier plates, and the limiting mechanism is used to realize the functions of goods delivery and limiting, saving the space occupied by using a motor and a push rod for goods delivery.

[0004] During the use of the existing internal shelf structure of a commercial freezer, due to the limited internal space of the commercial freezer, most of the shelf structures are fixed in size and spacing in advance and then installed inside the commercial freezer. In this way, the entire internal space of the commercial freezer is relatively rigid and cannot meet the placement of goods of different sizes. Moreover, the internal shelf structure of the commercial freezer in the above comparative case lacks an adjustable method, which reduces the applicable range of the commercial freezer and cannot effectively refrigerate some goods of special sizes.

[0005] Therefore, it is very necessary to invent an adjustable internal shelf structure of a commercial freezer to solve the above problems. Summary of the Utility Model

[0031] A shelf frame 12 is arranged above the upper bracket 10 and is used to carry refrigerated goods. A first telescopic rod 13 is fixedly installed on one side of the shelf frame 12. An extension rod 14 is movably connected inside the first telescopic rod 13. One end of the extension rod 14 is movably connected to a second telescopic rod 15. A second fixed knob 16 runs through the outside of the second telescopic rod 15. A movable telescopic rod 17 is arranged inside the shelf frame 12. The spacing between the first telescopic rod 13, the extension rod 14 and the second telescopic rod 15 outside the shelf frame 12 can be adjusted, so as to control the current length of the entire shelf frame 12 and expand the distance for placing goods. In this way, the internal shelf structure of the commercial refrigerator has an adjustable capacity under coordinated use, which not only meets the requirements for orderly refrigeration of goods of different sizes, but also makes full use of the internal space of the commercial refrigerator.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the resistance sleeve 5 is movably connected to the mounting sleeve 2, and the torsion spring 4 is symmetrically arranged with the central axis of the resistance sleeve 5. The torsion spring 4 can be extended and retracted to the inner sides of the mounting sleeve 2 by pulling and compressing the resistance sleeve 5. In this way, the I-shaped adjustment shelf 1 is inserted into the mounting sleeve 2, and the torsion spring 4 will drive the resistance sleeve 5 to rebound and firmly resist the two sides of the I-shaped adjustment shelf 1. This installation method is simple and convenient. The number of positioning screws 7 is set to multiple, and the multiple positioning screws 7 are evenly spaced on the I-shaped adjustment shelf 1.

In this way, the internal shelf structure of the commercial refrigerator has an adjustable ability, which not only meets the requirements of orderly refrigeration of goods of different sizes, but also makes full use of the internal space of the commercial refrigerator. Then, when placing the multi-layer shelf frame 12, you can select a suitable support reinforcement plate 20 according to the current spacing size and insert it into the upper reinforcement sleeve 18 and the lower reinforcement sleeve 19. In this way, the supporting capacity of the multi-layer shelf frame 12 is improved, and then after the shelf is assembled, the refrigerated goods can be placed on the shelf. Finally, after completing the installation and use of the internal shelf structure of the commercial refrigerator according to the above operation, the device is maintained daily, and the external power supply can be cut off if it is not used for a long time. In this way, the use process of the adjustable internal shelf structure of the commercial refrigerator is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
