Description

Technical Field

[0001] This application relates to the field of cold chain ice box placement racks, and in particular to a cold chain ice box freezing and warming placement rack. Background Art

[0002] A cold chain ice box is a low-temperature block used for the items to be transported to be stored at low temperature during cold chain transportation. Generally, a rectangular box is filled with a liquid that can be frozen, and then placed in a cold storage for freezing. After freezing, it is placed together with the items that need to be stored at low temperature and then transported. When the cold chain ice box needs to be recycled, the cold chain ice box needs to be placed in a high-temperature environment to melt the frozen substances inside. Therefore, the placement rack plays an important role in the freezing and warming processes of the cold chain ice box.

[0003] A processing rack for cold chain ice rows disclosed in a Chinese utility model (publication number: CN 211400428 U) includes a bracket, a placement plate is arranged on the bracket, a plurality of fixed racks are placed on the placement plate, at least two sliding grooves are opened on the top surface of the placement plate along its length direction, and first convex teeth are arranged along the length direction on the side where the two sliding grooves are away from each other. The fixed rack is V-shaped and elastic, both ends of the fixed rack have fixed blocks, and second convex teeth meshing with the first convex teeth are arranged on the fixed blocks. The fixed blocks are adapted to the sliding grooves and slide along the length direction of the sliding grooves. The utility model has the effect of facilitating the placement of ice boxes of different sizes on the shelf.

[0004] However, since there is no mechanism for preventing falling on the placement rack, during the use process, due to factors such as collision or improper placement, the items on the placement rack may fall, which is not conducive to safety. Therefore, a cold chain ice box freezing and warming placement rack is now proposed. Utility Model Content

[0005] In order to prevent the items on the placement rack from accidentally falling and improve the use safety, this application provides a cold chain ice box freezing and warming placement rack.

[0006] A cold chain ice box freezing and warming placement rack provided by this application adopts the following technical solution: A cold chain ice box freezing and warming placement rack includes two symmetrically arranged side plates and a plurality of equally spaced placement plates fixedly installed between the two side plates. A plurality of equally spaced inverted U-shaped frames are fixedly installed on the placement plates. A space for placing cold chain ice boxes is formed between two adjacent inverted U-shaped frames. A back frame is fixedly installed between the two side plates, and a shielding mechanism is installed on the upper surface of the placement plate.

The shielding mechanism shields the front side of the frame body, making it not easy for the cold chain ice box to fall from the front of the frame body. Thus, the cold chain ice box is restricted within the space between the two inverted U-shaped frames, achieving the purpose of preventing the cold chain ice box from falling and improving safety.

[0010] Preferably, a storage groove is formed on the upper surface of the placement plate. The bottom of the vertical rod is hinged to the inner bottom wall of the storage groove. The horizontal rod is located inside the storage groove.

[0011] By adopting the above technical solution, the setting of the storage groove realizes the storage of the vertical rod and the horizontal rod, so that the edge of the placement plate will not protrude, which is conducive to placing the cold chain ice box on the placement plate.

[0012] Preferably, both the vertical rod and the horizontal rod are aluminum alloy rods, and both the vertical rod and the horizontal rod are designed with a hollow structure.

[0013] By adopting the above technical solution, the vertical rod and the horizontal rod are made of aluminum alloy material, which has the characteristics of high strength and light weight. While effectively shielding the placed cold chain ice box, it is convenient for the staff to lift.

One end of the screw rod is fixedly connected to the output end of the motor. A fan assembly is slidably installed inside the back frame. A screw tube is fixedly installed on the back of the fan assembly. The screw tube is threadedly connected to the screw rod.

[0017] By adopting the above technical solution, by driving the screw rod to rotate forward and backward by the motor, the fan assembly moves horizontally back and forth inside the back frame. The fan assembly accelerates the rapid circulation of hot and cold air near the cold chain ice box, improving the efficiency of freezing or heating inside the cold chain ice box.

[0018] Preferably, sliding grooves are formed on the inner top wall and the inner bottom wall of the back frame, sliders are fixedly installed on both the top and the bottom of the fan assembly, and the sliders are slidably connected to the inside of the sliding grooves.

[0019] By adopting the above technical solution, the arrangement of the sliders and the sliding grooves standardizes the movement track of the fan assembly.

[0020] Preferably, a plurality of installation grooves are formed on the upper surface of the placement plate, the installation grooves are located between the two inverted U-shaped frames, and a plurality of rolling rollers are rotatably installed inside the installation grooves.

[0021] By adopting the above technical solution, through the arrangement of the rolling rollers, when placing or taking out the cold chain ice box, the cold chain ice box can be conveniently moved in or out between the two inverted U-shaped frames.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By using the combined setting of the back frame and the shielding mechanism, the back frame shields the rear side of the frame body, and it is not easy for the cold chain ice box to fall from the back of the frame body. The shielding mechanism shields the front side of the frame body, and it is not easy for the cold chain ice box to fall from the front of the frame body. Thus, the cold chain ice box is restricted within the space between the two inverted U-shaped frames, so as to achieve the purpose of preventing the cold chain ice box from falling and improve safety.
