The invention relates to an inserted type circulating fan. Frame parts are mounted on a frame; folding edges are formed on the periphery of a mounting plate of the frame; and an X-shaped angle support plate is arranged. The inserted type circulating fan is characterized in that a motor bracket and support screw rods used for adjusting the motor bracket up and down are mounted at the upper end of the angle support plate; a motor is mounted on the motor bracket; the frame parts comprise a first plummer block bearing which is mounted at the center of the frame, and a main shaft and a second plummer block bearing which are arranged in the first plummer block bearing; one end of the main shaft passes through the frame and extends out of a plane of the mounting plate of the frame; an impeller is mounted at one end of the main shaft; the other end of the main shaft is arranged in the second plummer block bearing; a first belt wheel is mounted at the other end of the main shaft; and the firstbelt wheel is connected with a second belt wheel mounted on a power output end of the motor through a triangle belt. The inserted type circulating fan has the advantages of simple structure, attractive appearance, steady and reliable operation, low maintenance cost and long service life, and is convenient and economical for installation.
