The frame 82 includes a substantially rectangular bottom plate 83, a first sidewall 84 perpendicularly extending up from a first side of the bottom plate 83, a second sidewall 85 perpendicularly extending up from a second side of the bottom plate 83 opposite to the first side, and a third sidewall 86 perpendicularly extending up from a third side of the bottom plate 83 and connected between the ends of the first and second sidewalls 84 and 85. The bottom plate 83, and the first to third sidewalls 84-86 cooperatively bound a receiving space 852. Three mushroom-headed second guiding posts 832 (shown in
Each fan 87 includes a substantially rectangular shell 872 and an impeller 873 received in the shell 872. The shell 872 includes two opposite boards 875 and 877, two opposite side plates 874, and a top plate 876. The board 875 defines a round air inlet 8752. The board 877 defines a round air outlet (not shown) aligning with the air inlet 8752. A substantially U-shaped resilient pressing portion 878 is formed on a junction of the top plate 876 and each side plate 874. The pressing portion 878 includes a first portion extending up from the corresponding side plate 874 and a second portion extending toward the other side plate 874 from a top of the first portion. Two protrusions 879 protrude from the first portion of the pressing portion 878.
The locking member 89 is substantially Z-shaped, and includes a resilient mounting piece 892, an operation piece 894 substantially parallel to the mounting piece 892, and a connecting piece 896 connected between the mounting piece 892 and the operation piece 894. A distal end of the mounting piece 892 opposite to the operation piece 894 defines two fixing holes 897. Two opposite tabs 898 extend from opposite sides of the mounting piece 892, away from the operation piece 894.
Referring to
The latching member 60 is mounted to a bottom surface of the connecting member 40 by means of two fasteners extending through the through holes 622 and engaging in the corresponding fixing holes 428. The tabs 642 are opposite to the connecting plate 42.
The bottom plate 83 is supported on a top surface of the connecting plate 42. The second guiding posts 832 may be slidably inserted into the second guiding slots 427 by virtue of the cutouts 429. Therefore, the fan assembly 80 is supported but slidable on the connecting member 40. The flanges 44 abut and restrain the outer surfaces of the first and second sidewalls 84 and 85. A screw 88 slidably extends through the positioning slot 442, and engages into the fixing hole 844.
The connecting member 40 together with the fan assembly 80 is inserted into one of the receiving spaces 29 through the opening 27. The first guiding posts 222 are slidably inserted into the first guiding slots 426 by means of the guiding cutouts 424.
The fan assembly 80 is moved inwards, until the screw 88 abuts against an end of the positioning slot 442 adjacent to the guiding cutouts 424. The fan assembly 80 is moved in further to move the connecting member 40 into place. The tabs 642 abut against the side of the bottom wall 22 between the slide slots 224 and adjacent to the opening 27, to deform the latching piece 64 toward the frame 82. After the tabs 642 have aligned with the slide slots 224, the latching piece 64 is released, therefore, the tabs 642 are slidably received in the slide slots 224. The fan assembly 80 is moved inwards, until the tabs 642 abut against the ends of the slide slots 224 away from the opening 27.
The tabs 898 abut against the partition board 28 to deform the mounting piece 892 toward the frame 82, until the tabs 898 are in alignment with the latching holes 282. The mounting piece 892 is released to make the tabs 898 latch into the latching holes 282.
Referring to
When the tabs 642 abut against the ends of the slide slots 224 adjacent to the opening 27, the screw 88 abuts against an end of the positioning slot 442 away from the guiding cutouts 424. The fans 87 are then fully extended out of the housing 20. The pressing portions 878 are pressed towards each other, and the protrusions 879 detach from the latching holes 846. Therefore, the fans 87 are ready to be moved away from the frame 82.
