[0002] In the cold chain transportation of food delivery, the choice of loading and unloading tools is crucial, as they not only affect transportation efficiency but also directly impact the freshness and safety of the food.

[0003] The existing cold chain transportation and loading / unloading tools for food distribution use forklifts. Forklifts are characterized by high mobility and high handling efficiency. In cold chain transportation, they are used to move food from pallets or containers into or out of the truck. Forklift handling equipment plays an important role in the loading and unloading process of cold chain transportation. It can quickly and accurately complete the handling of food, thus improving the efficiency of the entire cold chain transportation.

[0004] However, existing forklift loading and unloading tools place goods on the forklift outriggers when handling cold chain food. Since there are no protective measures on the outriggers during the transportation of goods, the goods are very easy to tip over, which poses a certain risk to workers. Therefore, a new loading and unloading tool for cold chain transportation of food is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cold chain transportation loading and unloading tool for food distribution, aiming to improve the problem that existing forklift loading and unloading tools are prone to tipping over when handling cold chain food, thus posing a certain risk to workers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3 An embodiment of this utility model includes a frame 1, with fork arms 2 symmetrically fixedly connected to the front side of the frame 1. The fork arms 2 are mainly used for cold chain transportation of food products. The fork arms 2 are composed of steel plates, steel pipes and steel wheels. Their length and width can be adjusted as needed to adapt to goods of different sizes and weights. The installation position and number of fork arms 2 can also be flexibly configured according to actual needs. Universal wheels 3 are fixedly connected to the bottom of the front side of each fork arm 2. Guide wheels 4 are fixedly connected to the center of the bottom of the frame 1. A hydraulic device 5 is fixedly connected to the rear side of the frame 1. The hydraulic device 5 is used to control the up and down movement of the fork arms 2. The hydraulic device 5 consists of an oil tank, a hydraulic pump, and a hydraulic cylinder. It achieves the lifting and lowering operation of the fork arm 2 through the pressure transmission of the oil. The performance of the hydraulic device 5 directly affects the operating efficiency and safety of the forklift. The top of the hydraulic device 5 is rotatably connected to the operating lever 6. The operating lever 6 connects the hydraulic system and the fork arm 2 and is used to control the up and down movement of the fork arm 2. The operating lever 6 is made of steel pipe or plastic pipe. Its length and shape can be adjusted according to the operator's height and usage habits to improve the convenience and comfort of operation. The bottom of the fork arm 2 is provided with a flipping component 7, and an adjustment component 8 is provided between the two fork arms 2.

[0024] The flipping assembly 7 includes a connecting plate 71 fixedly connected to the bottom surface of the fork arm 2. A movable plate 72 is symmetrically and slidably connected through the interior of the connecting plate 71. Each movable plate 72 has a first limiting hole 73 on its surface. A fixed plate 74 is fixedly connected between the two movable plates 72. Support wheels 75 are fixedly connected to the bottom of each fixed plate 74. A protective plate 76 is rotatably connected to the top of the movable plate 72. A connecting hole 77 is symmetrically provided at one end of the protective plate 76. A limiting post 78 is slidably connected inside the connecting hole 77. A spring 79 is fixedly connected between one end of the limiting post 78 and the inner wall of the connecting hole 77. A limiting plate 70 is rotatably connected to one end of the protective plate 76. The limiting post 78 is slidably connected inside the first limiting hole 73. The movable plate 72 and the fixed plate 74 are on the same horizontal line. The 6th arm and the fork arm 2 are on the same horizontal line. The opening of the connecting hole 77 limits the bottom of the limiting post 78. The limiting plate 70 is located on one side of the connecting hole 77 and is on the same horizontal line as the connecting hole 77. The first limiting hole 73 is the same length as the limiting post 78. The housing of the limiting post 78 is completely retracted into the interior of the connecting hole 77. By setting the protective plate 76 and the support wheel 75 in the flipping assembly 7, the load-bearing area of ​​the loading and unloading tool is increased when the protective plate 76 is not open, thereby reducing the possibility of tipping over during the loading and unloading of food cold chain transportation. At the same time, when the protective plate 76 is open, it can also protect the sides of the loaded and unloaded food, further preventing the danger of tipping over during the food cold chain transportation process and improving the safety of workers during the food cold chain transportation process.

[0025] Reference Figure 1 - Figure 3 The adjustment assembly 8 includes an adjustment rod 81 set on the top of the moving plate 72. A limit rod 82 is symmetrically fixedly connected to the bottom of the adjustment rod 81. Second limit holes 83 are evenly opened on the surface of the fork arm 2. The adjustment rod 81 is located on the inner side of the fork arm 2. The limit rod 82 is fixedly connected to the bottom two ends of the adjustment rod 81. The limit rod 82 is slidably connected inside the second limit hole 83. The length of the limit rod 82 is the same as the length of the second limit hole 83. Through the adjustment rod 81, the limit rod 82 and the second limit hole 83 on the surface of the moving plate 72 set in the adjustment assembly 8, the moving plate 72 can be adjusted according to the overall size of the food to be loaded and unloaded when the loading and unloading tool is used. This makes the device applicable to the loading and unloading of food goods of different sizes, thereby improving the practicality of the loading and unloading tool.

[0026] Working principle: In use, firstly, according to the overall size of the food to be loaded or unloaded, pull out the adjusting rod 81. At this time, the adjusting rod 81 drives the limiting rod 82 to move out of the second limiting hole 83, thereby freeing the moving plate 72 from the limitation of the limiting rod 82. Then, by pulling the moving plate 72 out to both sides, when the moving plate 72 reaches the required position, insert the limiting rod 82 into the designated second limiting hole 83 to limit the moving plate 72. Then, rotate the protective plate 76 to make the protective plates 76 on both sides stand upright. At this time, rotate the limiting plate 70 to release the limitation of the limiting post 78. Then, the spring 79 loses resistance and extends and retracts, thereby allowing the limiting post 78 to insert into the first limiting hole 73 to limit the protective plate 76. When the protective plate 76 is not open, the support wheel 75 increases the load-bearing area of ​​the loading and unloading tool when the protective plate 76 is not open, thereby reducing the possibility of tipping over during the loading and unloading of cold chain food distribution.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
