Welding rod heat-preservation box

The invention provides a welding rod heat-preservation box. The welding rod heat-preservation box comprises a box body and a box cover; the height of the box body is matched with the heights of welding rods, a plurality of springs are fixedly installed at the bottom of the box body, and a plurality of heating rods are installed in the space between the inner wall and the outer wall of the box body; and the box cover is hinged to the top of the box body and can cover the top of the box body. According to the welding rod heat-preservation box, the springs are arranged at the bottom of the box body to separate the welding rods, the situations that mutual rubbing of the welding rods causes falling-off of welding agents on the surfaces of the welding rods, the welding technological properties of the welding rods are lowered, and the services lives of the welding rods are shortened are avoided; the heating rods are arranged between the inner wall and the outer wall of the heat-preservation box, and on the basis that the volume of the heat-preservation box is not increased, the temperature in the heat-preservation box is ensured to be within the appropriate temperature range.
