[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A refrigerated carriage for a van includes a carriage. An opening and closing door is arranged on one side of the carriage. A spliced heat insulation board is arranged at the inner bottom of the carriage. The heat insulation board includes an isolation board and a frame. A plurality of through holes are arranged at equal intervals from left to right inside the isolation board. The frame is sleeved on the periphery of the heat insulation board. Avoidance holes corresponding to the through holes are arranged on the frame. A heat preservation pipe is inserted into each through hole. The heat preservation pipe is sequentially provided with an insulating layer, a vacuolar heat insulation layer, and a structural support layer from inside to outside. A first plug column is arranged inside one end of the heat preservation pipe, and a second plug column is arranged at the other end of the heat preservation pipe. Conductive sheets are fixedly installed at the ends of the first plug column and the second plug column that are close to each other. A wire is arranged inside the heat preservation pipe. One end of the wire is fixedly connected to the conductive sheet of the first plug column, and the other end of the wire is fixedly connected to the conductive sheet of the second plug column.

[0006] By adopting the above technical solution, different wires inside the heat-insulating pipe can cooperate with the slots on the first copper column and the extending protrusions on the second copper column to achieve electrical conduction for different purposes. When it is necessary to lay the heat-insulating board, multiple heat-insulating boards are laid on the inner bottom of the carriage in pairs, and then the slots on the first copper column are inserted into alignment with the extending protrusions on the second copper column, so that the wiring of different functions inside the carriage can be realized, without additional processing of the heat-insulating board, which improves the laying efficiency.

[0007] In a further embodiment, the periphery of the end of the extending protrusion of the second copper column away from the second copper column is provided with a shape with sharp corners chamfered.

[0008] By adopting the above technical solution, the chamfered structure helps to play a positioning role when the extending protrusion is docked with the slot, reducing the docking difficulty.

[0009] In a further embodiment, insulating sleeves are provided in the avoidance holes of the frame.

[0010] In a further embodiment, threads are provided on the outer walls at both ends of the heat-insulating pipe, and the first plug column and the second plug column are both screwed and fixed on the heat-insulating pipe.

[0011] In a further embodiment, both the first plug column and the second plug column are provided with a double-layer structure with a hollow interior. The interiors of the first plug column and the second plug column are both filled with foam glue, and both the first plug column and the second plug column are made of insulating materials.

[0012] In a further embodiment, a protective layer is provided on the outer wall of the wire.

[0013] In summary, the present utility model has the following beneficial effects:

[0014] 1. By the cooperation of different wires inside the heat-insulating pipe with the slots on the first copper column and the extending protrusions on the second copper column, electrical conduction for different purposes can be achieved.

[0020] Embodiment 1:

[0021] As Figure 1-2As shown in the figure, a refrigerated compartment of a van includes a compartment 1. A pair of opening doors 2 are provided on one side of the compartment 1. A spliced heat insulation board 3 is provided on the inner bottom of the compartment 1. The heat insulation board 3 includes an isolation board 31 and a frame 32. A plurality of through holes are equidistantly arranged from left to right inside the isolation board 31. The frame 32 is sleeved on the periphery of the heat insulation board 3. Avoidance holes corresponding to the through holes are provided on the frame 32. A heat preservation pipe 4 is inserted in each through hole. The heat preservation pipe 4 is sequentially provided with an insulating layer, a vacuum insulation layer and a structural support layer from the inside to the outside. A first plug column 5 is arranged inside one end of the heat preservation pipe 4. A second plug column 6 is arranged at the other end of the heat preservation pipe 4. Conductive sheets are fixedly installed at the ends of the first plug column 5 and the second plug column 6 close to each other. A wire is arranged inside the heat preservation pipe 4. One end of the wire is fixedly connected to the conductive sheet of the first plug column 5, and the other end of the wire is fixedly connected to the conductive sheet of the second plug column 6. A protective layer is arranged on the outer wall of the wire. A first shaft hole is provided at the central position of the end of the first plug column 5 away from the heat preservation pipe 4. A second shaft hole is provided at the central position of the end of the second plug column 6 away from the heat preservation pipe 4. A first copper column is inserted in the first shaft hole. The first copper column is electrically connected to the conductive sheet of the first plug column 5. A second copper column is inserted in the second shaft hole. The second copper column is electrically connected to the conductive sheet of the second plug column 6. A slot is arranged at the end of the first copper column away from the second copper column. An extension protrusion corresponding to the slot is arranged at the end of the second copper column away from the first copper column. The periphery of the end of the extension protrusion of the second copper column away from the second copper column is provided with an acute angle chamfered shape. Insulating sleeves are arranged in the avoidance holes of the frame 32. Threads are arranged on the outer walls of both ends of the heat preservation pipe 4. The first plug column 5 and the second plug column 6 are both screwed and fixed on the heat preservation pipe 4. The first plug column 5 and the second plug column 6 are both arranged as a double-layer structure with a hollow interior. The interiors of the first plug column 5 and the second plug column 6 are both filled with foam glue. The first plug column 5 and the second plug column 6 are both made of insulating materials. When actually in use, the length of the wire needs to be greater than the axial length of the heat preservation pipe to avoid stress concentration of the wire.

[0022] As Figure 2 shown, it can be seen that the extension protrusion of the second plug column 6 extends beyond the frame 32. Therefore, during the process of splicing two heat insulation boards 3, the docking of the first plug column and the second plug column is realized.

[0023] Specific implementation process: Different uses of electrical conduction can be realized by the cooperation of different wires inside the heat preservation pipe with the slots on the first copper column and the extension protrusions on the second copper column. When laying the heat insulation boards, lay multiple heat insulation boards in pairs on the inner bottom of the compartment, and then align and insert the slots on the first copper column with the extension protrusions on the second copper column, so that the wiring of different functions inside the compartment can be realized. There is no need to additionally process the heat insulation boards, which improves the laying efficiency.
