  "abstract": "A connecting structure of lamp rod and lamp base for all kinds of for lamps, comprising a lamp base coupled to a side of the wire connection box and a lamp rod inserted into the interior of the lamp base; wherein a socket is coupled to an end of the lamp base, and a guiding hole is protruded from a side of the lamp base to provide an embedding member for the fixture, and the embedding member further comprises a steel ball placed in a guiding groove of the lamp base in advance, a spring disposed behind the steel ball, and a stopcock disposed at the rear end of the spring; working together with a blocking groove disposed at the position at the head of the lamp rod corresponsive to the embedding member for accommodating the insertion of the lamp rod such that the resumption of spring pushes the steel ball back into its original position, and the steel ball will press against and be stuck in the blocking groove for inserting the lamp rod into the lamp base. After the user has bought the lamp, the user just needs to insert the lamp rod into the lamp base.",
  "claims": [
    "1. An electrical connecting structure for a lamp, comprising: a lamp rod; a lamp base; the lamp base coupled to a side of a wire connection box; an embedding member in the lamp base; a lamp rod inserted into the lamp base; the wire connection box further comprising a through hole, and having the lamp base at its bottom surface; the lamp base comprising a sheathing hole at the position corresponsive to the through hole of the wire connection box; a socket coupled to the end of the lamp base for receiving the insertion of the lamp rod; and a guiding hole on a side of the lamp base for engaging the embedding member; the embedding member, further comprising a steel ball placed in a guiding groove of the lamp base in advance, a spring disposed behind the steel ball, and a stopcock disposed at the rear end of the spring; and the front-end diameter of the guiding hole is slightly smaller than the diameter of the steel ball; the lamp rod having a head; the lamp rod head being substantially in a shape corresponsive to the shape of the sheathing hole, and the head having a blocking groove at the position corresponsive to the embedding member of the lamp base; the blocking groove and the embedding member cooperating such that the head, when inserted into the sheathing hole, is secured therein; the head continuing into the socket of the lamp base to conduct electricity, after the lamp rod being inserted into the sheathing hole; such arrangement facilitating assembly by providing both mechanical and electrical connection by just inserting the lamp rod into the lamp base.",
    "2. An electrical connecting structure for a lamp, as claimed in claim 1, wherein: said lamp base further comprises a locking base corresponsive to a screw hole of the wire connection box; the locking base being disposed at the bottom of the lamp base for receiving a screw bolt passing through the screw hole at the bottom of the wire connection box and being secured on the locking base in order to fix the lamp base to the interior of the wire connection box.",
    "3. An electrical connecting structure for a lamp, as claimed in claim 1, wherein: said sheathing hole is a substantially rectangular hole with both lateral sides curved."

  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates to a do-it-yourself connecting structure of lamp rod and lamp base; by means of a guiding hole protruded from a side of the lamp base, an embedding member coupled onto the guiding hole, and working together with a blocking groove disposed at the position at the head of the lamp rod corresponsive to the embedding member of the lamp base, the present invention provides a way to let the head of the lamp rod push the steel ball backward and compress the spring so that after the lamp rod is inserted, the resumption of the spring pushes the steel ball back to its original position, and the steel ball presses against the blocking groove to insert the lamp rod into the lamp base. Such arrangement enables users to assemble the lamp on their own.\n\n2. Description of the Related Art\n\nThe conventional structure of inserting a conductive set of a lamp, regardless a wall lamp, a table lamp, or a floor lamp, uses screws and nuts for the fixing. However, this kind of assembly by screws and nuts may easily collide the finished goods during the assembling, and has to use working tools such as wrench and screwdriver for the fixing. The friction produced during the assembling may expose the electric wire easily and may even cause the hazard of electric shock. Therefore, the traditional way causes trouble for the assembling, and is definitely not suitable for DIY users to assemble the lamp by themselves. The manufacturers have to assemble the wire connection box with the lamp rod first before selling the lamp, which may increase the cost.",
