The embodiments disclosed herein provide an adjustable wash basin drain wherein a fitting angle of the contact surfaces between the wash basin and the drain can be adjusted to achieve a better seal between the wash basin and the drain. The wash basin drain may include a split-type drain flange that includes an upper connector seat, a lower connector seat, and a flange connector. The upper connector seat is configured to snap fit to an upper end of a water discharge hole of the wash basin. The lower connector seat is connected to a water discharge pipe, and may be disposed beyond a bottom end of the wash basin. The flange connector connects the upper connector seat with the lower connector seat.

A connector for connecting a fluid pipeline includes an inner socket, which is a columnar body having a channel, and both ends defined as a first end and a second end. The inner socket has a guide portion, an attaching portion, an anti-leak portion and a connecting portion sequentially arranged on the outer side from the first end to the second end; the first end is socketed into an end of a tube by the guide portion; the attaching portion is a spiral concave groove on an outer side of the inner socket for attaching an inner side of the tube; the anti-leak portion is between an end of the tube and the connecting portion for sealing an opening of the tube; and the connecting portion is between the anti-leak portion and the second end and exposed from the tube for connecting another connecting portion of another connector.

A connection device for the fluidic connection of a suction tube to a function unit. The connection device includes a first hollow-cylindrical connection section and a second hollow-cylindrical connection section. One of the connection sections is connectable or connected to the suction tube and the other connection section is connectable or connected to the function unit. One of the connection sections is located at least partly within the other connection section and with its outer periphery bears on the inner periphery of the other connection section, where the two connection sections are rotatably mounted, in order to provide a rotation compensation for the suction tube, and where an electrical connection for providing an antistatic function exists between the two connection sections. The first connection section includes a spring section which is deformable in the radial direction and with which the bearing contact on the second connection element takes place.

A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

An apparatus comprising a sleeve. The sleeve has an outer surface and a flange extending from the outer surface. The flange has a first surface for engaging an edge of first flexible hose and a second surface for engaging a union. The first surface of the flange has a radial length substantially equal to a thickness of the edge of the first flexible hose. The sleeve counteracts a deflection of the first flexible hose and the second flexible hose into a flow path created through the first flexible hose and the second flexible hose when the first flexible hose and the second flexible hose are coupled together using the union, the sleeve, and a pair of fittings.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.
