Vehicle-mounted portable food sampling storage box

The utility model discloses a vehicle-mounted portable food sampling containing box which comprises a supporting mechanism used for supporting a device, a refrigeration mechanism, a hand pull ring, a heat insulation mechanism and supporting feet, the refrigeration mechanism is arranged in the supporting mechanism, the hand pull ring is arranged at the top of the supporting mechanism, and the heat insulation mechanism is arranged on the supporting mechanism. The heat insulation mechanism is arranged below the supporting mechanism, the supporting feet are fixed to the four corners of the bottom of the buffering mechanism through screws, and the buffering mechanism and the heating mechanism are used for damping the device. According to the buffering mechanism, when the device shakes due to vehicle driving, the fixing frame slides relative to the buffering frame and moves downwards, at the moment, the two traction rods drive the two sliding blocks to move oppositely in the length direction of the limiting rod, an
