Extendable instrument cabinet
An extendable instrument cabinet includes a rectangular framework and an extension frame assembly. By the extension frame assembly connected to the rectangular framework, the instrument cabinet can enhance its capacity. The extension frame assembly includes an end frame and a side frame. The rectangular framework can be selectively mounted with the end frame or the side frame, as desired. Besides, the rectangular framework can be mounted with more than one end frame or more than one side frame in conjunction with fasteners, through holes, end frame through holes, and side frame through holes. Furthermore, each of the end frame and the side frame has a bottom provided with a foot structure for supporting its weight.
1. Field of the Invention
The present invention relates to an extendable instrument cabinet, and more particularly to one having an extension frame assembly connected to a rectangular framework to enhance its capacity by means of fasteners, a side frame and an end frame.
2. Description of the Prior Art
A convention instrument cabinet, as published in TW Utility Model No. M356203 is used for a machine or a server. The space of the apparatus room must be planned in advance, and the main frame of each instrument cabinet is assembled. Then, each instrument is mounted in each instrument cabinet. The loading capacity of each instrument cabinet is fixed, and the size of each instrument cabinet is not adjustable. In order to make good use of the space of the apparatus room, each instrument cabinet is against another one. This is not flexible for operation. When the instrument in one instrument cabinet needs expanding, there is no enough space for moving the cabinet. In addition, because the loading capacity of each instrument cabinet is fixed, it is not easy to update the instrument. Besides, the cables of the instrument are difficult to manage. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
SUMMARY OF THE INVENTIONAccording to the present invention, there is provided an extendable instrument cabinet comprising a rectangular framework including four support racks erected at four corners thereof, an upper frame connected to upper ends of the four support racks, and a lower frame connected to lower ends of the four support racks to form front and rear ends and left and right sides, each of the upper frame, the lower frame and the support racks being formed with a plurality of through holes; and an, extension frame assembly including an end frame and a side frame. By fasteners, the side frame and the end frame are connected to the rectangular framework, respectively. In addition, the side frame and the end frame may be further mounted with another side frame and another end frame depending on the demand of the user so as to extend their lengths as desired.
A first object of the present invention is that the instrument placed in the rectangular framework can be expanded by mounting with the side frame and the end frame.
A second object of the present invention is that the bottoms of the side frame and the end frame are provided with foot structures for supporting the weights of the side frame and the end frame.
A third object of the present invention is that the installation of the side frame and the end frame is completed by the fasteners inserted through the through holes, the side frame through holes, the end frame through holes, providing a fast and easy way for installation.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
Referring to
The rectangular framework 10 includes four support racks 101 erected at four corners thereof, an upper frame 102 connected to upper ends of the four support racks 101, and a lower frame 103 connected to lower ends of the four support racks 101 to form front and rear ends E and left and right sides S. Each of the upper frame 102, the lower frame 103 and the support racks 101 is formed with a plurality of through holes T.
The extension frame assembly 20 includes an end frame 21, at least two end frame through holes 211, a side frame 22, at least two side frame through holes 221, and a plurality of fasteners L. The side frame 22 corresponds in size to the left and right sides S of the rectangular framework 10. The end frame 21 corresponds in size to the front and rear ends E of the rectangular framework 10. The side frame through holes 221 are formed on the side frame 22. By the fasteners L inserted through the side frame through holes 221 and the through holes T of the relative support racks 101, the side frame 22 is connected to the relative support racks 101 at the left or right side S of the rectangular framework 10. The end frame through holes 211 are formed on the end frame 21. By the fasteners L inserted through the end frame through holes 211 and the through holes T of the relative support racks 101, the end frame 21 is connected to the relative support racks 101 at the front or rear end E of the rectangular framework 10, referring to
