  • Patent number: 6746145
    Abstract: A detachable lamp assembly device comprises a lamp seat and a lamp rod. A U shape reduce portion is formed at two lateral sides and an upper surface of the lamp rod. A U shape embedding block covers upon the reduced portion. The U shape embedding block has a through hole at a position corresponding to the positioning hole. A top center of the embedding block has an elastomer. When the lamp rod inserts into the lamp seat, the elastomer will eject the embedding block upwards. Thereby, the embedding block will be buckled to the embedding hole; and thus the lamp seat is conductive to the lamp rod. A user can assemble the lamp rod by insetting it into the lamp seat easily; and thus, the lamp is detachable for storage and transfer with a smaller volume.

  • Patent number: 6743978
    Abstract: A wire connection box with a rapibly-assembled lamp rod or inserting rod having: a retaining seat installed at a via hole at a lateral side of the wire connection box and an inserting rod inserted in the retaining seat. A front end of the inserting rod with respect to the retaining seat is firmly secured with a rapidly-connecting joint secured to a front end of the retaining seat. In this wire connection box, the inserting rod can be pulled out from the retaining seat for packaging, transferring and storage. Since the wire connection box and the inserting rod can be detached for reducing the volume, the retaining seat inserted by the inserting rod is assembled in the wire connection box. When assembly, it is only necessary to insert the inserting rod into the retaining seat for use. No other tool, such as studs, is needed. Thereby, the user can assemble the wire connection box by himself or herself.
