DETAILED DESCRIPTION

[0025] The technical problem of the present application is effectively solved by providing a nursing trolley with a heat preservation layer. In medical care, some items that need to be stored at low temperature, such as vaccines, blood products, and test samples, are often transported. When transported by the above-mentioned nursing trolley, the external temperature can easily affect the items that need to be stored at low temperature, causing them to deteriorate. In use, the heat source box is first pulled out. Then the frozen ice bag is placed in the heat source box. Then the heat source box is put back into the heat preservation box body. The low temperature generated by the ice bag will be transmitted to the heat preservation box body through the heat source box, forming a space with a lower temperature inside the heat preservation box body. The low temperature storage box is pulled out. The items that need to be transported at low temperature are placed in the low temperature storage box. Then the low temperature storage box is slid back into position. During the resetting of the low temperature storage box and the heat source box, the magnetic attraction strips at the side ends of the low temperature storage box and the heat source box will be attracted to the side ends of the heat preservation box body, preventing the low temperature storage box and the heat source box from falling out during movement. The heat insulation connecting column, the heat preservation box shell, the first heat preservation side plate, and the second heat preservation side plate installed on the heat preservation box body, the low temperature storage box, and the heat source box ensure that the interior of the heat preservation box body is completely in a heat preservation space. The heat preservation box body does not directly contact other objects outside, reducing the influence of external temperature on the temperature inside the heat preservation box body. This achieves the effect of facilitating the transportation of items that need to be stored at low temperature. When in use, if the user is tall, the two knobs can be turned to rotate the threaded rod counterclockwise. Since the threaded rod is threadedly connected to the threaded sleeve, counterclockwise rotation of the threaded rod will push the handle upward, causing the handle to slide upward. Conversely, if the user is short, the handle can be slid downward by reversing the two knobs. This achieves the effect of being able to adjust according to the height of the user.
