  • Publication number: 20240237824
    Abstract: An anti-overturning device for cabinet and its cabinet structure is disclosed in the present invention. The anti-overturning device comprises a first fixing member, a second fixing component and a connecting part. The first fixing component is used for arranging detachably on the outside of the cabinet bottom. The second fixing component includes at least a second opening, and the second opening is used for fixing on the auxiliary wheel or on the ground. The anti-overturning devices are provided evenly on the periphery of the cabinet bottom. The anti-overturning devices change the horizontal position of the original overturning pivot of the cabinet and enlarge the overturning angle to prevent from overturning the cabinet.

  • Patent number: 11970492
    Abstract: The present invention provides 11-arylcinnolino[2,3-f]phenanthridinium salt compounds and method for producing the same by highly regioselective synthesis of 11-phenylimino[2,3-f]phenanthridin-9-ium salts from 2-azobiaryls and alkenes under catalysis of palladium, through double oxidative C—H coupling of alkenes, to give the polycyclic cinnolinophenanthridinium salts in moderate yields. The reaction mechanism involves ortho C—H olefination of 2-azobiaryls by alkenes, intramolecular aza-Michael addition, ?-hydride elimination, electrophilic palladation followed by intramolecular C—H activation and reductive elimination. The prepared quaternary ammonium salts are candidate materials for solution-processable OLED and bioimaging materials.

  • Publication number: 20200335904
    Abstract: A transceiver module includes a housing, a latch, a springy sheet, and a pull tab. The latch has a wedging portion and is movably connected to the housing. The springy sheet is disposed between the housing and the latch. The pull tab is connected to the latch. When the pull tab moves from a first pull tab position to a second pull tab position, the pull tab applies a force to move the latch with relative to the housing and to carry the wedging portion to move from a first wedging position to a second wedging position, thereby deforming the springy sheet. When the force applied by the pull tab is removed, the springy sheet pushes the wedging portion to move from the second wedging position to the first wedging position.
