Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is to provide a standing box with multi-direction opening doors, more particularly to a structure in which all panels of the box can be opened, and with the help of two fixed horizontal bars, and one side of the box itself as a pivot which enabling it to turn the box, making circuit installation free and convenient. 
     2. Description of the Prior Art 
     The box structure herein is directed to electronic appliances, or equipment of circuit parts. It is a six-sided box made of metal, with a front door. Inside the box there are several horizontal or vertical bars with structures of angle frames for circuit boards. There is only one front door on the traditional box structure of the kind, all circuiting and maintenance works have to go through the same door which hampers the work especially of those in the corners or comparatively deeper part of the box which can&#39;t be reach easily. This is the draw-back of the traditional box as it is time consuming and has very little efficiency when it comes to installation and maintenance. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a structure in which all doors (front, side, back doors and the box itself) can be turned or opened, making it time saving and convenient when installation or maintenance is needed. 
     To enable a further understanding of the feature of the present invention, the brief description of the drawing below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in FIG.  1  and FIG. 4, the structure of the present invention is screw fastened between two vertical frames  70  separately with two fixed horizontal bars  30  which on both sides there is a reversed-n shape bottom board  31  on which there are alignment portions  40  which tightly lock four corners from back of box  10  into position; wherein, a top panel  11 , a bottom panel  12 , a front panel  14 , two side panels  13  and a back panel  15  are joint together forming a six-sided closed box  10 . 
     As shown in FIG.  2  and FIG. 5, on one side of the front panel  14  and of the side panels  13  respectively at top end and bottom end, there are alignment portions  40  which lock the top panel  11  and bottom panel  12  in place. 
     As shown in FIG.  5  and FIG. 6, each alignment portion  40  consists of an alignment board  41  which on one side is equipped with two pivot caps  42 ,  43 . An inserting bar  44  with a curved handle  441  is inserted into the pivot caps  42 , 43  between which there is a elastic part  45  and a washer  46  is designed to place against the end of the elastic part  45  thereby supports the inserting bar  44  in a protruding state. 
     As shown in FIG.  1  and FIG. 5, the alignment portions  40  located on both sides of the upper and lower horizontal bar  30  are locked into the top panel  11  and bottom panel  12  with the ends of the inserting bars  44 . As shown in FIG. 3, when the upper and lower alignment portions  40  on the same side of the box  10  are pulled outward and loosened, the alignment portions  40  on the other side will work as a pivot to help one side of the box  10  to disconnect from the vertical frame  70  enabling it to be turned and opened. 
     As shown in FIG. 2, FIG.  6  and FIG. 8, when the said alignment portions  40  are applied respectively on the top and bottom of one side of the front panel  14 , and inserted into the top panel  11  and bottom panel  12 , of the front panel  14  as a pivot connection, enabling it to open the same way using the alignment portions  40  as a pivot. 
     As shown in FIG. 2, for the side panels  13 , the same can be applied. When alignment portion  40  are fixed on top and bottom of one side of the side panels  13 , wherein, the inserting bars  44  are then inserted into the top panel  11  and bottom panel  12 , so that the side panels  13  can be turned and opened in the same manner as that of the front panel. 
     As shown in FIG. 7, a bent blocking L shape slat  61  is installed on one side of the bottom panel  12  and a lock hole  611  is on top of it. When pressing the side panel  13  onto one side of the box  10 , a bottom portion  131  of the side panel  13  reaching the front of the bent blocking L shape slat  61 , so as to screw fasten them together with a bolt. The back panel  15  as shown in FIG. 2, is seldom used, and so it is usually fixed tight with screws. 
     As shown in FIG. 2, the invention herein consists of several alignment portions  40  utilized as the connecting structures of the box  10 . Therefore, the front panel  14  and side panels  13  pivotally to be opened, making it convenient to perform maintenance work and installation of circuit inside of the box  10 . 
     As shown in FIG. 2, FIG.  4  and FIG. 6, a rectangular frame structure made of holed circuit frames  20  are install inside of the box  10  and a groove  21  mounting at the bottom of the frame structure. One side of the circuit frames  20  is connected to one inner side of the box  10  by a double angle supporting stand  50  on which surface there are bolt holes  51  and the bottom side of the circuit frame  20  is placed on top of the said supporting stand  50 . As shown in FIG.  5  and FIG. 6, a axle tube  23  is placed against the bottom of the double angle supporting stand  50  running through the bottom of the groove  21  of the circuit frame  20 . Furthermore, a pivot is formed when one bolt  22  goes through the axle tube  23  and the bolt hole  51  of the double angle supporting stand  51 , enabling the circuit frame  20  to be suitably opened and closed by applying the structure. 
     As shown in FIG.  2  and FIG. 7, a block  60  with lock hole  611  is installed relatively at a free end of the circuit frame  20  inside of the box  10 . When enclosing the circuit frame  20  within the box  10 , the circuit frame  20  is accordingly located adjacent to block  60  by fastening with a screw. 
     The present invention has been very well thought and has the following advantages: 
     Mainly all doors can be conveniently opened, making circuit installation more accurate, and efficient. 
     A smooth connection of flexible circuit frames by a structure that works together with the said supporting stand, pivot and bolts. 
     Two fixed horizontal bars that work together with the alignment portions, mounting the box onto the two vertical frames. When the alignment portions are put away on one side, the other side will be used as a pivot which enables the box to be turned and opened. 
     The present invention is a result of the inventor&#39;s persevering attitude, continuous hard work and development, which is believed to meet all patent requirements and is hereby submitted to the patent examiner for reviewing and granting of commensurate patent right.
