The invention provides a bionic robot fish provided with a rising module and a tail module, relating to the bionic robot fish used underwater and aiming at solving the defects of the existing bionic robot fishes that the rising speed is low; rising characteristics are indistinct and adjusting the tail fin movement-diameter is inconvenient, etc. The other end of a screw (11) is fixedly connected with a piston (4) through a screw end closure (3), the piston (4) is arranged in a cylinder (1), and one end of a cylinder end closure (6) is fixedly connected with the cylinder (1); a straight-spur cone gearwheel (38) is arranged on a central shaft (43) and two ends of a central shaft (43) are rotationally connected with two sides of a box body (39), and two sets of sliding mechanism assemblies (84) are respectively arranged on a first disk (22) and a second disk (44) through a first eccentric shaft (25) and a second eccentric shaft (41). The bionic robot fish provided by the invention has a better rising characteristic and better bionic effect and can easily realize the adjusting to the tail fin movement-diameter of the robot fish so as to lead the swaying of the fish body to be rare and the moving stability to be better.

A pump unit is provided having a wet-running electric motor, wherein a rotor of the pump unit can be driven by the electric motor at a maximum speed of greater than 20,000 rev / min, and the rotor is sealed off axially in the region of a suction port.

The invention relates to an aircraft with a connection element for connecting at least one first conduit element or the like positioned in a supply chamber of an aircraft with at least one second conduit element positioned in a cabin chamber of the aircraft, wherein supply chamber and cabin chamber are separated from each other by means of a separation element, substantially comprising a connection part comprising fastening elements for fastening the first and second conduit element.Known connection elements have the disadvantage that there occur sealing problems due to the fastening of the fastening element at the outside of the connection part at the end facing the cabin chamber. A further disadvantage is that the connection elements protrude into the cabin chamber and form stumble edges there.In that at least the fastening element for the fastening the conduit element of the cabin chamber is provided within the connection part, there may be realised a compact structural shape which does not protrude from the separating element into the cabin chamber, and which may in addition be reliably sealed.

In the invention, there is a closed U-shaped groove on the interface of a rigid container and close to the U-shaped groove is put flexible covering material. A hose filled certain pressure gases inside is built-in the flexible material. The pressure produced because of the hose channel expansion makes the flexible material and the interface of the rigid container seal. The hose can be gas-filled and air-released quickly, so as to realize the sealing and seal-removing quickly between the flexible material and the interface of the rigid container.

A motor vehicle lock module is provided for actuating a vehicle component which includes a locking element and a Bowden cable with a Bowden cable grommet and a core which is guided movably in the Bowden cable sleeve for the transmission of an adjusting force. The core is connected to the adjusting element at a first end. The Bowden cable sleeve can be received at least at a first end in an end piece. Furthermore, a one-piece seal is provided, which encloses the first end of the Bowden cable sleeve in a first region and extends in a second region via a region of the core emerging from the Bowden cable sleeve and sealing on the core is applied. The seal is designed to be pressed into the Bowden cable grommet in an end-piece-received condition in the first region from an end piece.

The invention relates to a GW6B type disconnecting switch open-type transmission case which mainly comprises an open-type case body, rotary shafts, conducting clips, a tension spring, an upper conducting pipe and a lower conducting pipe, wherein the open-type case body is mainly composed of conducting bars and a wiring board, the number of the rotary shafts is two, the two rotary shafts are arranged in parallel between the two conducting bars, the two conducting clips rotate in the reversed direction through a transmission mechanism, a voltage-sharing ball is arranged at the upper end of the upper conducting pipe, the lower conducting pipe is installed in the conducting clips, the upper conducting pipe and the lower conducting pipe are connected through a connecting pipe, the two ends of the rotary shafts are connected with the conducting bars through bearings A respectively, bearings B are arranged between the conducting clips and the rotary shafts, annular grooves are formed in the two ends of a shaft sleeve respectively, the shaft sleeve is limited and fixed through cover plates, the tension spring is obliquely arranged between the two conducting bars, and a tension spring protection sleeve is arranged on the outer surface of the tension spring in a sleeved mode. The GW6B type disconnecting switch open-type transmission case has the advantages that due to the fact that the disconnecting switch transmission case is open, working staff can observe, maintain and debug transmission pieces inside conveniently.
