  • Publication number: 20150202622
    Abstract: A quantification tube, capable of achieving concentration quantification by means of centrifugal force. The concentrated quantification centrifugal tube includes a tube cover, a tube body, and a small volume trapezoid-column-shape tube body. The tube body is connected to the small volume trapezoid-column-shape tube body. The tube body can be filled with liquid substance, and the small volume trapezoid-column-shape tube body at the bottom portion is a concentration area, while the tube cover has the function of tight seal. After the tube is filled with liquid substance, and through actions of centrifugal force, the material in the liquid substance can be centrifuged into small volume trapezoid-column-shape tube body at the bottom of the tube body. Due to the design of trapezoid-column-shape tube body at the bottom of the tube body, the concentration ratio of the concentrated quantification centrifugal tube can be varied from 1 to infinite.

  • Patent number: 6966529
    Abstract: A foldable supporting framework comprises a retaining seat has an upper positioning sheet and a lower positioning sheet. At least one movable block is rotatably fixed to the upper and lower positioning sheets. There are at least two supporting posts; one supporting post being locked to the fixing threaded hole of the sealed side. Each of the other supporting posts is locked to the screw hole of a respective movable block. Thereby, at least two supporting posts are locked to the sealed side and the movable blocks. An axial rod is inserted into the upper positioning hole and the lower positioning hole of the retaining seat, and the axial rod is provided to lock other object. When the movable blocks rotate around the studs, each supporting post can be expanded so that all the supporting posts are aligned to reduce the volume of the supporting framework.

  • Publication number: 20050248156
    Abstract: An improved structure lamp pipe insert connector comprised of a locking connector component situated between upper and lower lamp pipes, the locking connector component comprised of a threaded rod, a lock sleeve fastened onto the threaded rod, and constraining rings respectively sleeved (not fastened) onto the two ends of the threaded rod and, furthermore, situated at the two sides of the lock sleeve. The interior of the constraining ring is a sloped surface and a plurality of detent slots are disposed along its inner circumferential extent and, after a spring is prepositioned on the sloped surface, it is then sleeved onto the threaded rod. Furthermore, there are revolving guide ring elements with beveled sides, each revolving guide ring element having guide blocks aligned with the constraining ring detent slot positions and capable of entry into the detent slots, thereby providing for the synchronous rotation of the revolving guide ring elements and the constraining rings.

  • Patent number: 6945806
    Abstract: A folding lamp rod and junction box structure in which the connector block has an access opening in its the top surface and, furthermore, the free extremity of an elastic tab at the side of the access opening extends into the access opening. A matching sawtooth-shaped inset section angles upward from the top surface at the end of the connector block and, furthermore, after the inset section is inserted into the mounting base socket, a spring at the mounting base top surface is pushed slightly upward, the rebound force of the spring then directed against the connector block to retain it while plugged into the mounting base.

  • Patent number: 6875919
    Abstract: A folding lamp rod and junction box structure for lamps comprised of a junction box and lamp rods hinged to the junction box. The junction box has a plurality of portals appropriately arrayed along the plane of its circumference and, furthermore, a pivot hole is formed in the top surface at the lateral edge of each portal in the junction box to provide for movably locating the lamp rods. Each lamp rod has a joint section at its proximal section that is hinged to the junction box and, furthermore, the joint section is coupled via the junction box the pivot hole. The lamp rod has a spring element situated at an appropriate area and, furthermore, the vertex portion of the spring element protrudes slightly to the circumferential edge. When the joint section is conjoined to the junction box, the spring element vertex portion engages the lateral edge of the junction box portal, thereby securing the lamp rod onto the junction box portal.

  • Patent number: 6811347
    Abstract: An improved lamp post insertional conjoinment structure consisting of a locking connector component ensleeved between an upper and a lower lamp post, with the locking connector component comprised of a threaded rod having a neck section at its leading and trailing extremities, a sleeve coupling in which the threaded rod is installed through the center, and a prong ring fastened onto the upper and lower extremities of the threaded rod and positioned at each of the two sides of the sleeve coupling. The prong ring has spring elements that extend from its circumferential edge, each spring element also having an indented pawl section and, furthermore, the pawl sections engage the threaded rod neck sections such that when the free extremities at the end sections of the spring elements turn as the prong rings rotate, they are propped open at a suitable rate and firmly postured against the interior circular walls of the lamp posts.
