Title: Lamp assembling device with orientation adjustable lamp post

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to lamp assembling device, and particularly to a lamp assembling device with an orientation adjustable lamp post, wherein a stud passes through a limiting reed, and a through hole of a positioning sheet to be locked into a locking hole of an adjusting rod. Thus, the adjusting rod, positioning sheet and limiting reed are locked as an integral body. 
     Referring to FIG. 6, a prior art lamp post is illustrated. A lamp assembling device includes a retainer  6  fixed to a distal end of a lamp rod, a positioning rod  7  locked to the retainer  6  and a lamp post  3  firmly secured to a top of the positioning rod  7 . A lower end of the positioning rod  7  is vertically bent with a positioning sheet  71 . A screw rod A locks into the lamp rod A from a screw hole  711  in a center of the positioning sheet  71 . By locking the positioning rod  7  to a distal end of the lamp rod A, the assembly of the lamp rod A to the lamp post  3  is performed only at one predetermined orientation. Thus, the orientation is unchangeable as desired. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a lamp assembling device with an orientation adjustable lamp post. In a retaining seat, a positioning sheet is locked to the distal end of the lamp rod. An upper section of a vertical surface of the positioning sheet has a locking hole. A lower end of the adjusting rod has a through hole. An embedding hole is formed on the adjusting rod at an upper side of the through hole. Thereby, a stud passes through the limiting reed and the locking hole of the positioning sheet to be locked into the through hole of the adjusting rod. Thus, the adjusting rod, positioning sheet and limiting reed are locked as an integral body. After locking, one free end of the limiting reed exactly extends into an embedding hole of the adjusting rod. As a result, the lamp post is adjustable.

     BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIGS. 1 and 2, the structure of the present invention may be understood clearly. The present invention is formed by a retaining seat  1  firmly secured to a distal end of a lamp rod A, an adjusting rod  7  locking to the retaining seat  1 , and a lamp post  3  firmly secured to a top of the adjusting rod  2 . 
     In the retaining seat  1 , a positioning sheet  13  is locked to the distal end of the lamp rod A by using a screw rod  11  and a nut  17 . An upper section of a vertical surface of the positioning sheet  13  has a locking hole  131 . A limiting reed  14  is locked to the through hole  131  by a stud P. A free end  141  of the limiting reed  14  is inclined inwards so as to be embedded into the embedding hole  22  at a lower end of the adjusting rod  2 . 
     The lower end of the adjusting rod  2  has a through hole  21  at a position coupled to the locking hole  131  of the positioning sheet  13 . An embedding hole  22  is formed on the adjusting rod  2  at the upper side of the through hole  21 . Thereby, the stud P passes through the limiting reed  14  and the locking hole  131  of the positioning sheet  13  to be locked into the locking through  21  of the adjusting rod  2 . Thus, the adjusting rod  2 , positioning sheet  13  and limiting reed  14  are locked as an integral body. After locking, the inward inclined free end  141  of the limiting reed  14  exactly extends into the embedding hole  22  of the adjusting rod  2 . 
     When the locking orientation of the adjusting rod  2  is adjusted, it is only necessary to release the stud P so that the adjusting rod  2  and the positioning sheet  13  are released. Then the adjusting rod  2  is screwed downwards to a predetermined orientation. The stud P is screwed again so that the adjusting rod  2  can drive the lamp post  3  to be fixed to a desired orientation (referring to FIG.  2 A). 
     Thereby, the lamp can be assembled convenient and the orientation thereof can be adjusted easily. 
     Referring to FIGS. 3 and 4, another embodiment of the present invention is illustrated. The retaining seat  1  contains a positioning sheet  13 A ( 13 B). Each of two sides of the positioning sheet  13 A ( 13 B) is extended with a locking sheet  132  ( 133 ). Each locking sheet has a locking hole  134  ( 135 ). A lower end of the adjusting rod  2  has a through hole  21  at a position coupled to the locking hole  134  ( 135 ) of the locking sheet  132  ( 133 ). A stud P passes through a limiting reed  14 ; the locking hole  134  ( 135 ) in the respective locking sheet  132  ( 133 ); and the through hole  21  in the adjusting rod  2  so as to lock the limiting reed  14 ; the locking sheet  132  ( 133 ) and the adjusting rod  2  together. Thereby, an inclined free end of the limiting reed is inserted into an embedding hole of the adjusting rod. Thus, the lamp post is adjustable by above components. 
     The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
