Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a fixing structure for
computer mainboard, and more particularly, to a fixing structure
for computer mainboard that can fix the mainboard without removing
the screws and is convenient in use.
[0003] 2. Related Art
[0004] The computer industry develops at an amazing speed.
According to statistics, the speed of the CPU in a computer is
doubled every 1.5 years. Now, comparing the CPU 8088 in the early
times with the P4 at present, the speed is raised several hundred
times, and several types of the fixing module of the CPU have also
been developed. At first, the CPU was directly fixed on the
mainboard, then the CPU was plugged into a socket (Socket 7, Slot
1) by pins, and at present, the P4 CPU is soldered on a socket by
the surface mounting technology (SMT). As the CPU generates a lot
of heat in operation, a good heat sink has to be used to dissipate
heat, thus protecting the CPU from breakdowns or damages. In view
of the above, the current fixing modules of CPUs all comprise
fixing devices for fixing heatsink fins or fans, so as to ensure
the normal operation of the CPUs.
[0005] Please refer to FIG. 1 of a schematic view of the joining
manner of the conventional fixing structure for computer mainboard.
As shown in FIG. 1, a reinforcing back board P20 is added to a
mainboard P10, so as to improve the capability of the mainboard 10
to bear the combined weight of the CPU, loading slot, fixing frame,
heatsink fin, fixing clamp or fan, wherein the fixing frame,
heatsink fin, fixing clamp and fan form a heatsink structure of the
CPU. Moreover, to protect the CPU and other elements, a guard board
P30 is added to the mainboard. Therefore, screws P41 are usually
adopted to effectively join the above three boards (the mainboard
P10, back board P20 and guard board P30) by means of locking.
However, as the current computer components can be upgraded, when a
user wants to upgrade the computer components, the screws P41 for
locking the above three boards have to be removed, which makes the
upgrading process very inconvenient.
[0006] Therefore, the mainboard P10, back board P20, and guard
board P30 are joined with the screws P41 by means of locking, thus
causing inconvenience as the screws P41 have to be removed first,
and meanwhile, much time is needed for fastening the screws P41.
Therefore, it is an objective of research and development in the
industry to re-design a fixing structure for computer mainboard
which is convenient in use and reduces the time needed for
fastening the screws.
SUMMARY OF THE INVENTION
[0007] Accordingly, an objective of the present invention is to
provide a fixing structure for computer mainboard, so as to solve
the inconvenience as screws have to be removed in the conventional
art that utilizes screws for locking, and meanwhile to overcome the
disadvantage in the conventional art that disassembling tools have
to be used to effectively loosen the locking with screws.
[0008] To achieve the above objective, the present invention
provides a fixing structure for computer mainboard, so as to fix
and support a computer mainboard. The fixing structure for computer
mainboard comprises a mainboard, a guard board, a back board and at
least one fixing pillar. The mainboard comprises at least one snap
hole and at least one fixing hole. The guard board stacked on the
mainboard has at least one snap pillar for penetrating the snap
hole and disposed at a position corresponding to the snap hole on
the mainboard. Moreover, the back board is stacked on the other
side of the mainboard opposite to the guard board, and has at least
one penetrating position and a fixing position. In addition, the
back board has at least one gourd-shaped hole and a fastening hole.
The gourd-shaped hole has a snap portion and a penetrating portion.
When the back board is at the penetrating position, the above
penetrating portion is corresponding to the snap hole and lets the
snap pillar penetrate. Besides, when the back board is at the
fixing position, the snap pillar is snapped at the snap portion.
Meanwhile, the fastening hole is corresponding to the fixing hole,
and when the back board is at the fixing position, the fixing
pillar penetrates the fixing hole of the mainboard and is fixed in
the fastening hole of the back board.
[0009] The present invention is a fixing structure for computer
mainboard. Through the implementation of the fixing and supporting
structure of a computer mainboard, the computer mainboard can be
joined without the locking by screws. Moreover, as the screws do
not have to be removed, the fixing and supporting structure of the
computer mainboard can be effectively separated without
disassembling tools. Therefore, the present invention is convenient
in use, and doesn't increase the time for the locking process.
[0010] To acquire further understandings to the objective,
structural features and functions of the present invention, they
are illustrated in detail below with reference to the related
embodiments and drawings.
