Description

Technical Field

[0001] The utility model belongs to the technical field of cold storage, and particularly relates to a novel quick-freezing and refrigerating device. Background Art

[0002] Food cold storage is a building used for freezing and refrigerating food. It uses artificial refrigeration to keep the temperature inside the storage at a certain level. In order to reduce the heat input from the outside, the floor, walls and roof of the cold storage are covered with a certain thickness of moisture-proof, air-proof and heat-insulating layers. Food cold storage can be widely used in food factories, dairy factories, fruit and vegetable warehouses, egg warehouses, hotels, supermarkets, troops, etc. It is mainly used for constant temperature storage of dairy products, meat, seafood, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea and other foods.

[0003] At present, the quick-freezing refrigeration and refrigeration devices in the prior art still have some shortcomings in the actual use process. For example, fresh goods are first put into the quick-freezing machine, and after quick-freezing processing, the center temperature of the food is quickly frozen to -18 degrees, and then transferred to a -18 to -25 degree cold storage for long-term storage; for food processing with small output and fast turnover, two sets of equipment are equipped, which occupies a large space and has a high investment cost. Secondly, in order to facilitate the loading of goods in the cold storage, it is sometimes necessary to push the transport vehicle in, and at this time, pads or slope pads need to be placed at the entrance of the cold storage door. However, due to the lack of a connection mechanism between the cold storage and the pads, when the vehicle body presses over the pads, a gap will be generated between the pads and the cold storage, affecting the loading and unloading of goods on the transfer cart.

When the plug block is inserted into the slot, the card block and the card slot are aligned. At this time, the spring resets and pushes the card block connected to the movable plate into the card slot to fix it. When disassembling, you only need to pull the two handles on the stainless steel insulation storage body at the same time, so that the handles drive the movable plates to slide away from each other through the connecting rod, so that the card block connected to the movable plate can be separated from the card slot, so that the cushion block can be quickly disassembled and assembled;

[0017] Third, when a single person disassembles the cushion block, he only needs to pull the handle on each side to move it to the side away from the cushion block. The handle drives the limit plate connected to the movable plate to slide in the limit groove through the connecting rod. When the limit plate moves to the limit hole of the limit groove, turn the hand-tightening bolt to insert its threaded end into the limit hole. When the movable plates at two places are limited, the limit plate is separated from the card slot through the card block connected to the movable plate, and the cushion block can be taken out.
