One side of therotary door 52 c is pivoted to theside plate 11 via the hinge means 51 c, so that therotary door 52 c can open or shield theopening 111 via the hinge means 51 c. - The other side of the
rotary door 52 c, opposite the hinge means 51 c, is provided with afirst fixing portion 522 c (hook in the present embodiment). Theside plate 11 is provided with a second fixing portion 112 (hole in the present embodiment) that can be connected to the first fixingportions 522 c correspondingly. Via this arrangement, after therotary door 52 c shields theopening 111, therotary door 52 c is fixed on theside plate 11 via the connection between thefirst fixing portion 522 c and the second fixing portion 112 (i.e., the hook is engaged in the hole). - Therefore, after the
fan body 30 is removed from thefan accommodating space 22 of the fixingsupport 20, therotary door 52 c can be rotated to shield theopening 111, thereby protecting the electronic components within thecasing 10. - Please refer to
FIGS. 9 to 12 , which show a fifth embodiment of the present invention. The difference between the fifth embodiment and the first embodiment is described as follows. - The protection means 50 d comprises a
knob 51 d, a two-side gear wheel 52 d, a plurality of drivengear wheels 53 d, a plurality of drivinggear wheels 54 d, a plurality oflinkages 55 d and a plurality ofshutters 56 d. One end of theknob 51 d is provided with a fixingshaft 511 d. The distal end of the fixingshaft 511 d is provided with a knobdriving gear wheel 512 d. - The inside and outside of the two-
side gear wheel 52 d are provided withinner teeth 521 d andouter teeth 522 d. The drivengear wheels 53 d are engaged with theinner teeth 521 d, and the knobdriving gear wheel 512 d is engaged with theouter teeth 522 d, so that the two-side gear wheel 52 d, the drivengear wheels 53 d and the knobdriving gear wheel 512 d are drivingly connected with each other. - The
driving gear wheels 54 d are engaged with the corresponding drivengear wheels 53 d respectively. One end of each of thelinkages 55 d is connected to the center of the rotating shaft of one of thedriving gear wheels 54 d and thus can rotate synchronously with one of thedriving gear wheels 54 d. The other end of each of thelinkages 55 d are fixed on one side surfaces of theshutters 56 d, thereby causing theshutters 56 d to move. Of course, theshutters 56 d can be provided thereon with a plurality of through holes (not shown) for allowing air to pass through. - When the user turns the
knob 51 d, the knobdriving gear wheel 512 d drives the two-side gear wheel 52 d to rotate reversely (FIG. 10 ), which drives the drivengear wheels 53 d to rotate in the same direction as the two-side gear wheel 52 d. Further, thedriving gear wheels 54 d rotate to cause the other ends of thelinkages 52 d to displace, so that theshutters 56 d can move respectively along a curved trajectory T, thereby opening theshutters 56 d. When the user turns theknob 51 d reversely (FIG. 13 ), the operation mentioned the above can be similarly applied, thereby moving theshutters 56 d to shield theopenings 111. - Therefore, after the
fan body 30 is detached from thecasing 10, theshutters 56 d shield theopenings 111, thereby avoiding the user from touching the electronic components within thecasing 10 and preventing dust in the air from entering thecasing 10. - According to the above, with the fan mounting structure of the present invention, the fan body can be removed directly from the opening provided outside the casing to perform replacement or maintenance. Further, after the fan body is removed, the protection means can protect the electronic components within the casing from suffering damage due to external forces and avoid the user from touching the electronic components within the casing or dust in the air from entering the casing. Thus, the product may not suffer damage.
- While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
