A cooling fan device for a computer including a fan device having a primary housing and a side housing. A computer casing a side walls having an area with air permeable holes, right positioning slots, and a left positioning slot. Projection parts of the primary housing are latched into the right positioning slots, and a flange part on a press plate is latched into the left positioning slot, such that the fan device can be quickly assembled on or disassembled from the computer casing without using screws.
The primary object of present invention is to provide a cooling fan locking device for a computer, such that a fan device can be quickly assembled on or disassembled from a computer casing without using screws.
Referring to FIG. 1 and FIG. 2, the present invention is to provide a cooling fan locking device for a computer, including at least more than one fan device 10 composed of a primary housing 12, an exterior surface of which is provided with an area of ventilation holes 121, a back surface of which is provided with a sink 122 for latching with a fan 14, a side of which is provided with at least more than one insertion slot 124, and an edge at the other side of which is provided with at least more than one projection part 125; a side housing 16, an interior of which is protruded with a plurality of insertion pieces 161 which can be inserted into the insertion slots 124; and a flexible press plate 126, which is located at a side of the side housing 16, and a surface of which is provided with a transversal flange part 127 and a locking slot 128.
Referring to FIG. 3, a side wall 31 of a computer casing 30 is provided with an area of a plurality of air permeable holes 32 (as shown in FIG. 4), and a left and right walls of the area of air permeable holes 32 are provided with right positioning slots 33 and a left positioning slot 34, respectively.
The projection parts 125 of primary housing 12 can be latched into the right positioning slots 33, and the flange part 127 on the press plate 126 can be latched into the left positioning slot 34, such that the fan devices 10 can be locked and positioned at exteriors of the areas of air permeable holes 32 (as shown in FIG. 4).
Referring to FIG. 4 and FIG. 5, two projection parts 125 are transfixed into right positioning slots 33, such that the fan device 10 is positioned into the right positioning slots 33 and then rotated, to enable flange part 127 to be locked into left positioning slot 34. Referring to FIG. 4, as a predetermined thickness 302 is formed between the long-strip left positioning slot 34 and an outer edge 301 of a computer casing 30, the flange part 127 can be latched into the left positioning slot 34, and a locking slot 128 is exactly latched on the thickness 302, such that the fan device 10 can be latched and fixed on the casing 30. When the fan 14 starts operating, air can be blown into the casing 30 through air permeable holes 32 to cool down parts in the casing 30, wherein a side surface of an abut part 123 is abutted on a side wall 31 of the casing 30, such that once the primary housing 12 is subjected to external pressure, the abut part 123 can be abutted on the side wall 31 to enhance an intensity for sustaining with the force.
On the other hand, when the fan device 10 is to be taken out, as long as an operator uses fingers to press on a press plate 126, enabling the press plate 126 to be elastically deformed to be flexibly displaced toward a concaved part 129, and to pull it out, the press plate 126 will be released from the left positioning slot 34, and the projection parts 125 will be also removed from the right positioning slots 33. Therefore, the entire fan device 10 can be very quickly disassembled from the casing 30 (as shown in FIG. 5).
1. A cooling fan device for a computer, comprising:
at least one fan device having a primary housing, a side housing, and a fan; the primary housing has an area of ventilation holes located through an exterior surface thereof, a sink located on a back surface thereof for latching with the fan, a plurality of insertion slots located on a first side thereof, and a plurality of projection parts located on a second side thereof; the side housing has a plurality of insertion pieces protruding outwardly from an interior thereof and inserted into the plurality of insertion slots, and a flexible press plate located on a side of the side housing, the flexible press plate has a transversal flange part and a locking slot located on a surface thereof; and
a computer casing has a side wall having an area with a plurality of air permeable holes, right positioning slots located in a right wall relative to the area with the plurality of air permeable holes, and a left positioning slot located in a left wall relative to the area with the plurality of air permeable holes,
wherein the plurality of projection parts of primary housing are latched into the right positioning slots, and the flange part on the press plate is latched into the left positioning slot, the fan device is selectively connected to and removed from the computer casing.
2. The device according to claim 1, further comprising a concaved part located below the press plate, wherein, when the press plate is subjected to pressure, it is elastically displaced in the concaved part.
3. The device according to claim 1, wherein the second side of the primary housing is provided with an abut part abutting the side wall of the computer casing when the fan device is connected to the computer casing.
4. The device according to claim 1, wherein the right positioning slots are located on a vertical wall located at a side edge of the side wall, and the left positioning slot is located on a vertical wall located at a side of the air permeable holes.
