The utility model discloses a horizontal air supply structure of a high and low temperature test box. The horizontal air supply structure comprises a box body, an I-shaped plate, a vertical plate, a sliding rod, a sealing plate, an air inlet pipe, a fan, an attaching plate, a filter screen, a supporting plate, a pull rod, a first spring, a limiting rod, a first toothed plate, a rotating rod, a gear, a second toothed plate, a T-shaped rod and a second spring. Through the arrangement of a limiting mechanism, after the whole filter screen is used for a long time, a worker presses a limiting rod at the same time, and when the limiting rod enters a cavity in a pull rod, a retracted second spring drives a second toothed plate to reset, so that a rotating gear drives a first toothed plate to slide; and in the resetting process, the second toothed plates are gradually separated from the inserting grooves in the side walls of the attaching plates, so that when the two second toothed plates are completely separated fro
