Title: Do-it-yourself lamp

Description:
FIELD OF THE INVENTION 
     The present invention relates to lamp devices, and particularly to a do-it-yourself lamp, wherein in packaging, transferring, or storage, the lamp rod and seat can be separated for reducing the space required. Since the seat is assembled to a retaining tube of the seat, when the user buys the lamp, it is only necessary to insert the lamp rod into the seat for use. No other locking tool is necessary. Thereby, users can assembled the lamp rod and seat by himself (or herself). 
     BACKGROUND OF THE INVENTION 
     For prior art lamps, such as wall lamps, stand lamps, or ceiling lamps, the studs and nuts are used as locking tools. However, in such prior art locking method, the lamps are not only easily damaged, but also locking tools (such as spanners, or openers) are necessary in locking operation. In assembly, the electric wires are easily protruded out due to friction. Thereby, people easily get an electric shock. The prior art structure is not suitable to be assembled by users himself (or herself). The manufacturers must assembly the lamps in advance for sale. However, this will increase the space in transformation and storage and thus the cost is increased. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a do-it-yourself lamp which can improve the defects of the prior art, and the user can assemble the lamp structure by himself (or herself). 
     To achieve above objects, the present invention provides a do-it-yourself lamp comprises a seat, and a lamp rod arranged on the seat. The seat has a plurality of penetrated stepped holes and a positioning disk. The positioning disk has a plurality of through holes aligned to the stepped holes but having a smaller diameter. A receptacle passes through one of the through holes. A plurality of locking holes are arranged between the through holes. Thereby, a locking stud passes through a ground wire and then passes through the locking hole of the positioning disk. Then, it is locked to a lower end of the seat. After the positioning disk is locked, a bottom of the lamp rod is inserted with a joint in advance and one end portion of the joint is slightly protruded from the bottom end of the lamp rod. After inserting the lamp rod, the end portion of the joint slightly protruding from the bottom of the lamp rod is exactly inserted into the receptacle of the seat. 
     Thereby, in packaging, transferring, or storage, the lamp rod and seat can be separated for reducing the space required. Since the seat is assembled to a retaining tube of the seat, when the user buys the seat, it is only necessary to insert the lamp rod into the seat for use. No other locking tool is necessary. Thereby, users can assembled the lamp rod and seat by himself (or herself). 
    
    
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIG. 2, the structure of the do-it-yourself lamp of the present invention is illustrated. The do-it-yourself lamp of the present invention includes a seat  1 , and a lamp rod  2  arranged on the seat  1 . 
     The interior of the seat  1  has a plurality of penetrated stepped holes  11 . A large stepped hole  11 A of each stepped hole  11  is exactly inserted by a receptacle  14 , and the small stepped hole  11 B is exactly inserted by the joint  21  of the lamp rod  2 . At a side surface of the seat  1  has a plurality of threaded holes  12  for tightening a confining stud P as the confining stud P is locked in the stepped holes. 
     A cap  17  is installed upon a top surface of the seat  1 , and the cap  17  has a via hole  171  which is aligned to stepped holes  11  of the seat  1 . A lower end of the seat  1  is locked with a positioning disk  13  by a lock stud P 1 . The positioning disk  13  has a plurality of through holes  131  aligned to the stepped holes  11  but having a smaller diameter. The receptacle  14  can pass through one of the through holes  131 . A plurality of locking holes  132  are arranged between the through holes  131 . Thereby, the locking stud P 1  can pass through a ground wire  15  and then passes through the locking hole  132  of the positioning disk  13 . Then, it is locked to a lower end of the seat  1 . 
     After the positioning disk  13  is locked, the edge of the receptacle  14  exactly resists against the positioning disk  13  for preventing the plug from falling out. The larger section  141  of the receptacle  14  is exactly positioned in the stepped holes  11  of the seat  1  and the smaller section  142  thereof is protruded from the lower end of the positioning disk  13 . The bottom of the seat  1  is installed with an outer threaded section  16 . After the seat  1  is assembled with the positioning disk  13 , the receptacle  14  and the ground wire  15 , the outer threaded section  16  of the seat  1  can be locked into the retaining tube  3  of a wall lamp, stand lamp or a ceiling lamp. 
     The bottom of the lamp rod  2  is inserted with a joint  21  in advance and one end portion of the joint  21  is slightly protruded from the bottom of the lamp rod  2 . After inserting the lamp rod  2 , the end portion of the joint  21  slightly protruded from the bottom end of the lamp rod  2  is exactly inserted into the receptacle  14  of the seat  1 . 
     The operation of the present invention will be described herein with referring to FIG.  3 . The positioning disk  13  is locked to a lower end of the seat  1  in advance, and the stepped holes in the seat  1  is positioned with a joint  21  in advance. When the lamp rod  2  inserts into the seat  1 , the plug  22  at a bottom of the lamp rod  2  is exactly inserted into the receptacle  14  of the seat  1 . 
     Referring to FIGS. 4 and 5, another two embodiments of the present invention are illustrated. The seat  1 A has penetrated stepped holes  11 . Each hole  11  has confining grooves  111  at two sides thereof. Thereby, the receptacle  14  is exactly inserted into the large stepped hole  11 A of the seat  1 . A lower end of the seat  1  is locked with a positioning disk  13  by a lock stud P 1 . The positioning disk  13  has a plurality of through holes  131  at the center thereof and at positions aligned to the stepped holes  11 . The locking stud P 1  passes through a ground wire  15  and then passes through the through hole  131  at the center of the positioning disk  13 . Then, it is locked to a lower end of the seat  1 . 
     The lamp rod  2  has a ring  22  conformed to the stepped holes  11  of the seat  1  and has a resisting block  23  conformed to the confining grooves  111 . After lamp rod  2  inserts into, the seat  1 , the resisting block  23  exactly embeds to the confining groove  111  of the seat  1  for preventing the lamp rod  2  from rotation. The ring  22  of the lamp rod  2  exactly resists against a top end of the seat  1  for resisting against the lamp rod  2  from falling out (referring to FIG.  5 ). 
     A top of the outer threaded section  16  of the seat  1  has a neck portion  161 . At a portion of the neck portion  161  exactly aligned an edge of the stepped holes  11  has a threaded hole  12 . Thereby, the confining stud P may be locked to tighten the joint  21  (referring to FIG.  4 ). 
     Thereby, in packaging, transferring, or storage, the lamp rod  2  and seat  1  can be separated for reducing the space required. Since the seat  1  is assembled to a retaining tube of the seat  1 , when the user buys the seat  1 , it is only necessary to insert the lamp rod  2  into the seat  1  for use. No other locking tool is necessary. Thereby, users can assembled the lamp rod  2  and seat  1  by himself (or herself). 
     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.
