     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings and initially to  FIGS. 1-3 , a shelving unit in accordance with the preferred embodiment of the present invention comprises a backplane including an upright support  2 , a transverse connecting rack  1  detachably combined with the upright support  2 , a first connecting bracket  21  secured on the upright support  2 , a second connecting bracket  11  secured on the connecting rack  1  and detachably combined with the first connecting bracket  21 , and a fastening pin  22  extending through the first connecting bracket  21  and the second connecting bracket  11  to combine the first connecting bracket  21  and the second connecting bracket  11  together. 
     The first connecting bracket  21  of the backplane has a side provided with a hollow mounting seat  210 . The mounting seat  210  of the first connecting bracket  21  has an inner portion provided with a receiving space  211 . The mounting seat  210  of the first connecting bracket  21  is provided with two opposite protruding ears  212 , and the receiving space  211  of the mounting seat  210  is located between the two protruding ears  212  of the mounting seat  210 . Each of the two protruding ears  212  of the mounting seat  210  is provided with a first through hole  213 . 
     The second connecting bracket  11  of the backplane has a side provided with a mounting post  111  combined with the mounting seat  210  of the first connecting bracket  21  by the fastening pin  22 . The mounting post  111  of the second connecting bracket  11  is inserted into the receiving space  211  of the mounting seat  210  and is clamped between the two protruding ears  212  of the mounting seat  210 . The mounting post  111  of the second connecting bracket  11  is provided with a second through hole  112 . 
     The fastening pin  22  extends through the first through hole  213  of each of the two protruding ears  212  of the mounting seat  210  and the second through hole  112  of the mounting post  111  to combine the mounting seat  210  of the first connecting bracket  21  and the mounting post  111  of the second connecting bracket  11  together. 
     In assembly, the mounting post  111  of the second connecting bracket  11  is inserted into the receiving space  211  of the mounting seat  210  and is clamped between the two protruding ears  212  of the mounting seat  210 . Then, the fastening pin  22  extends through the first through hole  213  of each of the two protruding ears  212  of the mounting seat  210  and the second through hole  112  of the mounting post  111  to combine the mounting seat  210  of the first connecting bracket  21  and the mounting post  111  of the second connecting bracket  11  together and to combine the first connecting bracket  21  and the second connecting bracket  11  together so as to mount the connecting rack  1  onto the upright support  2 . 
     On the contrary, after the fastening pin  22  is removed from the first through hole  213  of each of the two protruding ears  212  of the mounting seat  210  and the second through hole  112  of the mounting post  111 , the mounting post  111  of the second connecting bracket  11  can be detached from the receiving space  211  of the mounting seat  210  so as to detach the connecting rack  1  from the upright support  2 . 
     Accordingly, the first connecting bracket  21  and the second connecting bracket  11  are combined together and detached from each other by the fastening pin  22 , so that the upright support  2  and the connecting rack  1  are assembled and disassembled easily and quickly, thereby facilitating a user assembling and disassembling the backplane of the shelving unit. In addition, the backplane of the shelving unit has a simplified construction, thereby decreasing the costs of fabrication and inconvenient to customers. 
     Referring to  FIGS. 4-6  with reference to  FIG. 2 , the shelving unit further comprises a support frame  3 , and the upright support  2  of the backplane is detachably mounted on the support frame  3 . 
     The support frame  3  is provided with at least one locking hole  32 . The locking hole  32  of the support frame  3  has an upper end provided with a circular passage  320  and a lower end provided with an elongate locking slot  322  having a dimension smaller than that of the circular passage  320 . The support frame  3  is further provided with a positioning hole  31 . The positioning hole  31  of the support frame  3  is located above the locking hole  32  of the support frame  3 . 
     The upright support  2  of the backplane is provided with at least one locking knob  24  detachably locked in the locking hole  32  of the support frame  3 . The locking knob  24  of the upright support  2  has a first end provided with a guide post  240  protruding outwardly from the upright support  2  and a second end provided with a circular locking piece  242  inserted through the circular passage  320  of the locking hole  32  and locked onto the locking slot  322  of the locking hole  32 . The guide post  240  of the locking knob  24  is inserted through the circular passage  320  of the locking hole  32  and is detachably locked in the locking slot  322  of the locking hole  32 . The locking piece  242  of the locking knob  24  has a dimension equal to that of the circular passage  320  of the locking hole  32  and greater than that of the locking slot  322  of the locking hole  32 . 
     The upright support  2  of the backplane is further provided with a positioning plug  23  detachably positioned in the positioning hole  31  of the support frame  3 . The positioning plug  23  of the upright support  2  is located above the locking knob  24  of the upright support  2  and is directed downward toward the positioning hole  31  of the support frame  3 . The positioning plug  23  of the upright support  2  is attached to the upright support  2  by a fixing strut  230 . The positioning plug  23  of the upright support  2  is positioned in the positioning hole  31  of the support frame  3  when the locking knob  24  of the upright support  2  is locked in the locking hole  32  of the support frame  3  and is detached from the positioning hole  31  of the support frame  3  when the locking knob  24  of the upright support  2  is unlocked from the locking hole  32  of the support frame  3 . 
     In assembly, when the upright support  2  of the backplane is mounted on the support frame  3 , the locking piece  242  of the locking knob  24  extends through and protrudes outwardly from the circular passage  320  of the locking hole  32 . Then, the upright support  2  of the backplane is moved downward relative to the support frame  3  by the gravity of the backplane so that the guide post  240  of the locking knob  24  is inserted into and locked in the locking slot  322  of the locking hole  32 , and the locking piece  242  of the locking knob  24  is locked onto the locking slot  322  of the locking hole  32 . At the same time, the positioning plug  23  of the upright support  2  is moved downward and positioned in the positioning hole  31  of the support frame  3  when the locking piece  242  of the locking knob  24  is locked onto the locking slot  322  of the locking hole  32 . 
     Referring to  FIG. 7  with reference to  FIGS. 4-6 , the support frame  3  is further provided with at least one screw bore  33 . The screw bore  33  of the support frame  3  is located above the locking hole  32  of the support frame  3 . The upright support  2  of the backplane is further provided with at least one fixing bore  25 . The fixing bore  25  of the upright support  2  is located above the locking knob  24  of the upright support  2 . The shelving unit further comprises at least one fastening bolt  4  extending through the fixing bore  25  of the upright support  2  and screwed into the screw bore  33  of the support frame  3  to combine the upright support  2  and the support frame  3  together. 
     Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
