  • Publication number: 20140319827
    Abstract: A pipe joint structure is used to prevent a tube and pipe joint, especially fluororesin pipe joint from slipping off. The pipe joint comprises a joint body, a fixed ring and a union nut. A jig is used to expand the tube end to become a flared end consisting of a conical surface and a tubular surface, and finally connect it to the conical surface and tubular surface on top of the tube connecting portion of the joint body. When the union nut is fastened to the locking thread of the tube connecting portion, its interior recess portion will couple with the bulging surface of fixed ring to ensure it to stay in a concentric position, thereby allowing the tube wall of sealed surface to be compressed evenly and secured firmly on said pipe joint so to achieve a seal and prevent it from slipping off.

  • Patent number: 8696149
    Abstract: The present invention relates to an improvement in the structure of luminous umbrella, using integrated illumination components. The components are ideal for luminous umbrella particularly designed to be used in the evening when visibility is poor, and can be used for other decoration purposes. The integrated illumination components of the present invention are constructed by combining illumination emitter of LED with bases of parts of umbrella, such as linkage members on slip ring, rib members on fixed collar and umbrella handle. When the illumination emitter of LED is mounted on the surface of these parts, the overall umbrella structure can be made smaller and lighter, and the flexibility of light source design can also be maximized. In particular, when base parts with high heat dissipation capability are used as the heat dissipating fins, the full performance of high-brightness illumination emitter of LED can be achieved. The integrated illumination components offer another advantage.

  • Patent number: 6619923
    Abstract: An integrated 3-D blade structure which consists of at least two integrated pieces made by one-time shaping. Each integrated piece has a plurality of shorter 3-D curved-face blades and the relative let-in structures. Via the let-in structures, it is easily to match with the at least two integrated pieces. Then, the plurality of shorter blades could be matched with adjacent blades, depending on different design, to form a complete 3-D curved-face blade, or keeping a little distance between the matching blades to become a “Multi-Row” blade structure. Originally, since the whole blade structure with complicate 3-D curved face has been divided into several shorter blades for manufacturing, they are made via plastic emergence with forming or wax forming. Therefore, not only the element amount is highly decreased, but also the cost for position and assembly of blades is going down.

  • Patent number: 6439835
    Abstract: An improved pump shell for a multistage metal working pump includes a plurality of pump shell units housed in series within a hollow cylindrical casing and has the impellers driven by a shaft. Each pump shell unit has a inner shell which forms a holding end at one side and a sealing flange at another side. The holding end of one pump shell may align and engage precisely and easily with the sealing flange of an adjacent pump shell unit to form a smooth fluid passage from the inlet of the impeller through the inner shell so that pumping efficiency may be enhanced with less turbulence. The sealing flange, holding end and the casing also form a close annular compartment for holding a seal ring inside to provide effective sealing function. The pump shell may be produced by stamping at low cost.
