The utility model discloses a novel universal shaft assembly, including bottom plate, be provided with fixed subassembly on the bottom plate, the fixed subassembly includes mounting seat, fixed base, bolt, first axle body and second axle body, the mounting seat fixed mounting is at the both ends of bottom plate's top, the fixed base can be detached and installed on the mounting seat, the bolt can be detached and installed between fixed base and mounting seat, first axle body and second axle body are placed on the mounting seat respectively, be provided with disassembly subassembly on the fixed base, the disassembly subassembly includes oil injection pipe, connecting pipe and resist the pole, oil injection pipe fixed mounting is on the fixed base, connecting pipe fixed mounting is on the oil injection pipe, resist the pole sliding connection on the connecting pipe, to solve the background art mentioned in the installation fixed time of current universal shaft, although the traditional method can ensure the firmness of universal shaft, when universal shaft needs to maintain or replace, the more complicated technical problem.

This invention provides a measuring cup with a lid, comprising: a cup body, a lid, and a handle. The cup body is also provided with graduation marks. It further includes: a snap-fit ​​structure, comprising a first snap-fit ​​element disposed on the edge of the lid and a second snap-fit ​​element disposed on the cup body, the first and second snap-fit ​​elements being releasably engaged; a lid-opening button disposed on the lid and located outside the lid edge near the handle; a movable connecting structure, one end of which is connected to the lid-opening button, and the other end of which is connected to the handle, to be linked with the lid-opening button, so that the lid can open and close as the lid-opening button moves, and remain at any position between a first position on the lid and a second position at the maximum opening; a guide edge is also provided on the inner edge of the lid: the guide edge extends along the inner surface edge of the lid from both sides of the lid-opening button, and the height of the guide edge gradually increases in the direction away from the lid-opening button; a groove is formed between the edge of the lid and the guide edge; and a sealing ring is disposed in the groove.

This invention belongs to the field of bipolar plate testing technology, specifically an automatic perforation testing device for hydrogen production bipolar plates. It includes a support base with an adjustable height frame on top; a load-bearing device on top of the adjustable height frame for holding the bipolar plate; and a rotating component located at the axis on the upper surface of the load-bearing device for twisting the bipolar plate. The load-bearing device includes a metal frame with fixing rods evenly inserted into its inner wall. This device can replace manual testing. Through a scanning component at fixed points, it twists the clamped and rotating bipolar plate, thereby detecting the flatness of the perforations on the outer surface of the bipolar plate. To ensure accuracy, the rotation speed and number of rotations of the bipolar plate can be controlled, ensuring the scanning component can perform a comprehensive inspection of the bipolar plate and avoiding missed or incorrect measurements.

The utility model relates to the technical field of wool textile, in particular to a gilling machine speed change adjustable device which is characterized in that a connecting piece is arranged in the center of a bottom plate of a gilling machine, and a side plate at one end of a pay-off wheel is connected in a sliding groove in the connecting piece in a sliding mode. A plurality of blades are evenly arranged on the outer edge of the side plate, a speed increasing nozzle and a speed reducing nozzle are arranged in the sliding groove, the speed increasing nozzle and the speed reducing nozzle are communicated with the main air pipe through a speed increasing branch flow channel and a speed reducing branch flow channel respectively, and the speed increasing branch flow channel and the speed reducing branch flow channel are each provided with an electromagnetic valve. Wherein the airflow spraying direction of the speed increasing nozzle is along the rotation direction of the pay-off wheel, and the airflow spraying direction of the speed reducing nozzle is opposite to the rotation direction of the pay-off wheel. Therefore, the rotation speed of the pay-off wheel can be rapidly increased or decreased through cooperation of the two. The rotating speed of the pay-off wheel can adapt to the traction speed of a roller more quickly, and adverse effects are reduced.
