STRUCTURE FOR COMBINING TWO SETS OF HALF-WIDTH RACK-TYPE MACHINE
CASES TO FORM A FULL-WIDTH MACHINE CASE
Abstract
A structure for combining two sets of half-width rack-type
machine cases to form a full-width machine case includes two
half-width type machine cases to be combined together. Each
half-width type machine case has one side plate provided with at
least one positioning member protruding outward and another
opposite side plate bored with receiving holes at the locations
respectively corresponding with the positioning members. Thus, two
half-width type machine cases abutting and juxtaposed can easily be
combined into a full-width type machine case by having the
positioning members of one half-width machine case engaged and
fixed with the receiving holes of another half-width machine
case.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a combination structure of a
machine case, particularly to one that is a half-width rack-type
machine case.
[0003] 2. Description of the Prior Art
[0004] Generally, industrial rack-type machine cases, which need to
be installed in an equipment cabinet, are restricted to a standard
size. For instance, the standard width of each rack-type machine
case is nineteen inches, and (U) is used as a unit for height.
[0005] The height specifications of machine cases include 1U, 2U,
4U and the like, and the lowest one 1U is 4.4 centimeters in
height. Further, half-width type machine cases are developed and
used, which are respectively a half of a standard width of a
rack-type machine case and can be installed singly or combined
together to form a full-width machine case (nineteen inches) to be
installed for use. A conventional rack-type machine case, referring
to FIG. 1, includes two half-width type machine cases respectively
provided with a base board 1, which has opposite sides respectively
formed with a recessed groove 2 having a bottom side bored with a
plurality of threaded holes 3. To assemble these half-width machine
cases together, two half-width machine cases are first juxtaposed
in parallel and then an iron plate 4 is assembled in the adjacent
recessed grooves 2 of the two base boards 1. Subsequently, a
plurality of bolts 5 are respectively inserted through the insert
holes of the iron plate 4 and screwed in the threaded holes 3 to
secure the iron plate 4 in the two adjacent recessed grooves 2. For
combining two half-width machine cases together with great
stability, the opposite sides of the iron plate 4 need to use more
bolts 5 that are to be screwed spaced apart for firmly locking the
iron plate 4 in the two adjacent recessed grooves. So its
assemblage is complicated, taking a lot of time and also causing
much inconvenience when the two half-width machine cases are to be
disassembled.
SUMMARY OF THE INVENTION
[0006] The objective of this invention is to offer a structure for
combining two sets of half-width rack-type machine cases to form a
full-width machine case. Each half-width type machine case has one
side plate provided with at least one positioning member and
another opposite side plate bored with receiving holes at the
locations respectively corresponding with the positioning members.
By so designing, two half-width type machine cases can be combined
into a full-width type machine case by mutual engagement of the
positioning members of one half-width machine case and the
receiving holes of another. To assemble or disassemble a full-width
machine case, simply have the positioning members of one half-width
type machine case engaged in or disengaged from the receiving holes
of another half-width type machine case, simple and convenient in
assembling and disassembling.
BRIEF DESCRIPTION OF DRAWINGS
[0007] This invention will be better understood by referring to the
accompanying drawings, wherein:
[0008] FIG. 1 is an exploded perspective view of two sets of
conventional half-width machine cases to be combined together;
[0009] FIG. 2 is an exploded perspective view of two sets of
half-width rack type machine cases to be combined into a full-width
one in the present invention; and
[0010] FIG. 3 is a schematic view of two sets of half-width rack
type machine cases combined into a full-width one in the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] A preferred embodiment of a structure for combining two sets
of half-width rack type machine cases to form a full-width one in
the present invention, as shown in FIGS. 2 and 3, includes two
rectangular half-width type machine cases 10 adjacent and
juxtaposed to be combined together. Each half-width type machine
case 10 has a front and a rear section of one side plate
respectively formed with a threaded hole 11 for receiving a
corresponding positioning member 12 that is pivotally provided with
a rotary member 13 at the top portion. In this preferred
embodiment, the positioning member 12 is a bolt and the rotary
member 13 is a bearing, and thus the positioning members 12 can be
threadably locked on the side plate of the machine case 10.
Further, another opposite side plate of the half-width type machine
case 10 is bored with receiving holes 14 at the locations
respectively corresponding with the positioning members 12 so that
the positioning members 12 can be engaged and fitted therein. In
this preferred embodiment, the receiving hole 14 includes a round
hole 141 and an extension hole 142 communicating with the round
hole 141, and the hole diameter of the round hole 141 is
approximately the same as the maximum diametrical width of the
rotary member 13, while the hole diameter of the extension hole 142
is a little smaller than the maximum diametrical width of the
rotary member 13. Therefore, when the two half-width machine cases
10 are to be combined together, firstly, the positioning members 12
are respectively positioned in the receiving holes 14, and then the
rotary members 13 are transversely moved from the round holes 141
to the extension holes 142 to have the positioning members 12
engaged and positioned in the extension hole 142 to finish
combining two sets of half-width machine cases together to make up
a full-width machine case.
[0012] In order to have two half-width machine cases 10 connected
more closely, two half-width machine cases are respectively
provided with a back plate 15 abutting and connecting the side
plate, and having lower two sides respectively bored with a locking
hole 16. When the two half-width machine cases 10 are juxtaposed
and combined, two locking members 18 are respectively inserted
through two insert holes 171 of a linking member 17 and locked in
the locking holes 16 of the two abutting half-width machine cases
10. In this preferred embodiment, the linking member 17 is a
rectangular iron plate, the locking holes 16 are threaded holes
while the locking members 18 are bolts.
[0013] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
