The invention discloses a pipeline connecting device which comprises a joint body, a plurality of elastic strips, a locking nut, a first stop part and a second stop part, wherein the joint body is provided with a channel; the elastic strips are circumferentially distributed at the port of the channel of the joint body; one end of each elastic strip is fixedly connected with the joint body; the elastic strips are used for clamping a pipeline inserted into the channel; the locking nut is provided with a first end close to the joint body and a second end opposite to the first end; a conical surface is formed on the inner wall of the second end; the inner diameter of the conical surface is gradually increased along the entering direction of the pipeline; the conical surface is matched with the outer walls of the elastic strips to clamp the pipeline; the first stop part is arranged on the outer wall of the joint body or the outer walls of the elastic strips; and the second stop part is arranged on the inner wall of the first end of the locking nut and is used for being matched with the first stop part to stop the locking nut from being separated from the joint body or the elastic strips.

In a structure of fitting female and male connectors together, the female connector includes a female housing, and a female adapter which is provided on the female housing, and has a guide groove, and is fitted on a fitting portion provided at the male connector. The male connector includes a guide rib which is formed at the fitting portion, and is engageable in the guide groove. The female adapter can be rotated relative to the female housing to be placed at any of a plurality predetermined angular positions arranged with a fixed interval, and can be attached to the female housing. Only when the female adapter is rotated into a preselected one of the plurality predetermined angular positions, and is attached to the female housing of the female connector, the guide rib can be fitted in the guide groove, thereby allowing the female and male connectors to be fitted together.

In a blood bag system mounted in a centrifugation and separation apparatus, a filter is settable in different appropriate orientations at storage time and usage time, and first and second tubes and a filter are arranged respectively in appropriate orientations during use. The blood bag system includes a BC pooling bag for centrifugation of buffy coat, the filter for removing white blood cells from a supernatant liquid transferred from the BC pooling bag, a platelet preserving bag for reserving the supernatant liquid that has passed through the filter, the first tube connecting the BC pooling bag and an inlet of the filter, the second tube connecting the platelet preserving bag and an outlet of the filter, a cassette fixable in the centrifugation and separation apparatus, an attachment for holding the filter, and a hinge section tiltable relative to the cassette with reference to an axis in the circumferential direction.

The present invention relates to a spring member mounting structure, which is a structure for mounting a spring member on a cushion frame connecting side frames by use of a rear pipe. The spring member has rear clipping portions engaged with the rear pipe. Cover members, which are provided at seat central sides of connecting portions of the side frames and the rear pipe, have extension portions extending toward the seat central sides. The rear clipping portions abut on ends of the seat central sides of the extension portions, and are mounted to the rear pipe by width direction positioning of the spring member.

A metal mold for vulcanizing tire treads reliably preventing incorrect assembling of split pieces. The metal mold 1 for vulcanizing tire treads to form a tread of a tire, comprises a plurality of sector molds 3 equipped with a plurality of pieces 6 which are arranged on the inner circumferential surface of a casing 5 and are split in the circumferential direction in which a tread pattern of the tire is formed, wherein among the adjacent pieces 6 in the sector molds 3, a protuberance 8 is formed on the contact surface of the one piece 6, a dent 9 corresponding to the protuberance 8 is formed in the contact surface of the another piece 6, and the positions for forming the protuberance 8 and the dent 9 are differed for each of the adjacent pieces 6 in the sector molds 3.

The present invention relates to an assembling structure of a temperature-adjusting door in an air-conditioner for vehicles, in which setting pins are formed on a gear shaft and support members having pin holes are formed on a sliding door in such a way that the gear shaft and the sliding door are temporarily assembled with each other and the temporarily assembled gear shaft and the sliding door are separated from each other when the temporarily assembled gear shaft and sliding door are mounted to an air-conditioning case, thereby preventing misassembly of the temperature-adjusting door, improving assemblability, and reducing the size of the air-conditioning case.

System and method for assembling blow molded parts without the use of separate fasteners, including a tab-and-slot or dovetail mortise and tenon joint that includes a slide-and-lock tab feature. A retention barb on the tab slides along a ramp to engage with a receptacle within the slot. Tabs and slots can have varying widths to create mutual incompatibility with other joint components that are otherwise similarly constructed. An optional stopper on the tab and corresponding notch within the slot can add an additional axis of incompatibility with other joints throughout the assembly. These features prevent incorrect assembly and allow convenient redesigns.

A metal gasket includes a first metal plate having positioning holes, and a second metal plate laminated under the first metal plate. The second metal plate has positioning projections facing corresponding positioning holes and fitted into the facing corresponding positioning holes. At least one of the positioning holes does not match the other of the positioning holes in case the position holes are overlapped, and at least one of the positioning projections is not fitted into the other of the positioning holes.

A roller chain, in which when the roller chain comes into contact with guide members, the contact area is reduced, so that frictional resistance is decreased and friction loss generated during transmission of power is reduced. A roller chain is formed such that an outer link assembly comprising a pair of outer link plates and an inner link assembly comprising a pair of inner link plates are alternately connected along the pitch line of the chain to each other by pins. The distance from the pitch line of the roller chain to outermost edge surfaces of the link plates is the backside height. The backside height of the outer link plates is lower than the backside height of the inner link plates. When the roller chain contacts and slides on the guide members, the outer link plate does not come into contact with the guide members so that friction loss can be reduced. In some embodiments, some of the link plates are concave ellipsoidal (gourd-shaped) and others are non-concave ellipsoidal (cucumber-shaped).

The present invention relates to a steering shaft, and more particularly, to a steering shaft which is provided with a misassembly prevention structure for preventing misassembly when a shaft is inserted into and assembled with a yoke.

At least one set of locator pins is provided on the flange of an intake manifold which couple with an orifice provided on the flange of a throttle body to align the two parts to ensure that they are properly oriented when assembled. In addition, through holes are provided on the throttle body flange and threaded inserts are provided on the flange of the intake manifold. The locator pins are coupled with the orifices prior to inserting a bolt through the through holes to engage with the threads of the threaded insert. By providing the locator pins, the two flanges are held in a desired orientation so that the ducts of the two flanges are properly aligned to substantially eliminate a step or mismatch at the interface.
