The utility model provides a thermal insulation antitheft delivery box of a semiconductor, which belongs to the technical field of a small electric appliance. The delivery box is designed in order to realize that temporarily stored articles in the delivery box are automatically insulated and loss probability is reduced. The utility model adopts a model of carrying, hanging and locking and is fixed on a wall body, and the utility model is not easily moved. A load inductive switch installed on the lower part of a carrier plate at the bottom of a box body is used for controlling the timely locking of a box door and the working condition of a refrigeration block of the semiconductor. With the power supply polarity of the refrigeration block of the semiconductor changed, the refrigeration block of the semiconductor can carry out refrigeration or heat generation and realize the bi-directional thermal insulation of the delivery box. The utility model is not easily moved, and after an article is put inside, the box door can be automatically locked and closed, with thermal insulation carried out. The utility model can be used as a milk delivery box to realize that the milk is insulated and is not lost.
