Fan plug-in card structure

According to the fan card inserting structure, the strip-shaped groove is formed in the outer end face of the structural enclosure frame used for installing the fan unit, the rotary lock catch with the boss is connected to the interior of the strip-shaped groove through the shaft, the rotary lock catch is rotated to rotate in and out of the strip-shaped groove, and the boss matched with the limiting groove in the inserting groove is provided for the side wall of the structural enclosure frame; or a handle used for applying force during pulling out, the pulling force handle and the lock catch are combined into a rotary lock catch, so that the integration level is improved, and the space in the width direction is saved; and after the structural enclosure frame is inserted into the slot, the rotary lock catch is positioned in the strip-shaped groove, so that the space required by the longitudinal depth is saved. 本发明提供一种风扇插卡结构，通过在用于安装风扇单元的结构围框外端面设置条形槽，以及在条形槽中轴连一个带有凸台的旋转锁扣，通过转动旋转锁扣来从条形槽中转进转出，为结构围框的侧壁提供同插槽内限位槽配合的凸台
