Description

Technical Field

[0001] The utility model relates to the technical field of carriage storage racks, in particular to a refrigerated truck carriage storage rack. Background Art

[0002] A refrigerated truck refers to a closed van transport vehicle used to maintain the temperature of frozen or fresh goods. A refrigerated truck is a special refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane heat-insulated compartment. Two support frames are arranged inside the refrigerated compartment for placing items.

[0003] An existing refrigerated truck carriage storage rack (Publication No.: CN219257176U) has at least the following drawbacks: The device can quickly assemble the overall storage rack through the cooperation of columns and fixed pipes, so that the internal space of the carriage can be adjusted according to the transported items, and the overall practicability is good. Moreover, by using the cooperation between the hook and the clamping interface, that is, the top block continuously presses against the hook to ensure the stability and safety of the overall storage rack. By adjusting the position of the sliding block in the guiding chute, the position state of the placing plate can be flexibly changed, that is, the vertical state and the horizontal state can be flexibly adjusted. According to the transported refrigerated items, the overall storage and expansion of the storage rack can be quickly adjusted. However, when the porter conducts handling work in the refrigerated carriage and performs physical labor in the cold environment, and contacts the cold air after sweating, it is extremely easy to cause damage to the body. At the same time, the structural design of the device often requires a passage for handling to be left in the middle of the carriage, resulting in low space utilization rate.

A set of extension arms are arranged on both the left and right side walls of the fixed installation plate. A sliding rod is installed between the two sets of extension arms. A moving installation component is slidably installed on the two sliding rods. The moving installation component includes a moving installation plate. Two sets of sliding arms are integrally formed on the top surface of the moving installation plate. The two sets of sliding arms are respectively slidably connected to the two sliding rods. A set of connecting arms are symmetrically arranged on the left and right of the top surface of the moving installation plate. A bidirectional screw rod is rotatably connected between the connecting arms. The end of the bidirectional screw rod passes through the connecting arm and is coaxially connected to a second motor. A chute is formed on the top surface of the moving installation plate between the connecting arms. Two I-shaped sliders are slidably connected in the chute. A plurality of sets of placing rack components are connected and installed on the bottom surfaces of the two I-shaped sliders.

[0007] As a further solution of the present utility model, positioning holes are provided at the four corners of the fixed mounting plate, and a plug-in mounting groove is provided on the top surface of the fixed mounting plate. A straight rack is fixedly plugged in the plug-in mounting groove.
