Referring to fig. 1 to 7, the present embodiment provides a series fan frame and a fan, including a first fan frame 10 and a second fan frame 20, wherein an end of the first fan frame 10 facing the second fan frame 20 and an end of the second fan frame 20 facing the first fan frame 10 are respectively provided with a mounting surface 30, the mounting surface 30 of the first fan frame 10 is provided with a plurality of first grooves 11, and the mounting surface 30 of the second fan frame 20 is provided with a plurality of second fasteners 22 fastened with the first grooves 11. Specifically, the first recess 11 is engaged with the second latch 22, and the mounting surface 30 of the first fan frame 10 and the mounting surface 30 of the second fan frame 20 are attached to each other, so that the first fan frame 10 and the second fan frame 20 are connected in series.

The second buckle 22 comprises an elastic buckle part 32 and a positioning column 31 positioned on one side of the elastic buckle part 32; the first groove 11 is provided with an arc opening 33 parallel to the mounting surface 30 of the first fan frame 10, one side of the arc opening 33 is provided with a buckle opening 38, the other side is provided with a moving opening 39, the opening of the buckle opening 38 is larger than the opening of the moving opening 39, and the moving opening 39 is provided with a positioning notch 40.

The working principle that the first fan frame 10 and the second fan frame 20 are connected in series after the first groove 11 and the second buckle 22 are buckled and connected is as follows: when the second fan frame 20 is vertically buckled with the first fan frame 10 along the axis, any one of the second buckles 22 on the second fan frame 20 is aligned to the first groove 11 matched with the first fan frame 10, and then the elastic hook part 32 of the second buckle 22 is vertically inserted into the buckle opening 38 of the first groove 11; then, the second fan frame 20 rotates around the axis, the second catch 22 moves along the arc-shaped track of the arc-shaped opening 33 along with the rotation of the axis, at this time, the second catch 22 moves to the moving opening 39, because the moving opening 39 is smaller than the catch opening 38, the elastic hook portion 32 on the second catch 22 abuts against the bottom of the moving opening 39, the elastic hook portion 32 cannot be pulled out from the first groove 11, and only can move along the arc-shaped track of the moving opening 39 until the second catch 22 moves to the positioning notch 40 on the moving opening 39, and the positioning post 31 of the second catch 22 is inserted into the positioning notch 40, at this time, the second catch 22 is completely positioned in the positioning notch 40 and cannot move. At this time, the second latch 22 and the first groove 11 complete the engaging connection, and the second latch 22 and the first groove 11 limit the relative movement of the second fan frame 20 and the first fan frame 10 on the axis, and the positioning column 31 and the positioning notch 40 limit the relative rotation of the second fan frame 20 and the first fan frame 10 around the axis.

The second buckle 22 and the first groove 11 are provided to enable the second fan frame 20 to be buckled with the first fan frame 10, so as to achieve the serial connection installation of the first fan frame 10 and the second fan frame 20.
