This application discloses an optical cable lightning protection box, including a box body and a curved conduit located inside the box body. The curved conduit extends in a bent direction along the optical cable inlet to the optical cable outlet of the box body. The portion of the optical cable's reinforcing core extending into the box body includes two reinforcing core segments, one of which is located between the optical cable inlet and the end of the curved conduit facing the optical cable inlet, and the other reinforcing core segment is located between the end of the curved conduit facing the optical cable outlet and the optical cable outlet. The optical fiber bundle tube of the optical cable passes through the curved conduit. The inner diameter of the curved conduit at the bend is smaller than the inner diameter at other locations of the curved conduit, and the radius of curvature at the bend is not less than 4 cm. Reinforcing core fixing components are provided at the corresponding positions of the reinforcing core segments inside the box body, and the reinforcing core fixing component near the optical cable inlet is grounded. The optical cable lightning protection box provided by this application can improve the lightning protection effect and effectively protect the equipment in the computer room.

The invention discloses a glass bending and forming device. The glass bending and forming device comprises an extended opening component, a rear linkage pushing component, a connecting and supporting component and a transfer auxiliary component. The invention belongs to the field of glass forming, and particularly relates to a glass bending forming device. Through mutual cooperation of the extended opening component and the rear linkage pushing component on the connecting supporting component, the inclination angle of a connecting long rod is changed, a sliding piece slides in a sliding limiting piece, the distance between triangular pressing blocks connected with a fixedly-connected long shaft is adjusted, operation by operators is facilitated, and meanwhile the working efficiency is improved. According to actual requirements, the position of the rear linkage pushing component on the circular-truncated-cone-shaped guide block can be rapidly adjusted so as to adjust the distance between the triangular pressing blocks, so that the glass bending forming angle can be adjusted, operation is convenient, high efficiency and rapidness are achieved, the cooling or dismounting and mounting time of a mold is saved, the working efficiency is improved, and the production cost is reduced. And the working difficulty of workers is reduced.

The utility model belongs to cigarette equipment technical field discloses a ROFA conveying trolley track cleaning device and ROFA conveying trolley. ROFA conveying trolley includes ROFA conveying trolley body and ROFA conveying trolley track cleaning device. ROFA conveying trolley track cleaning device includes first connecting plate, second connecting plate, tow rope, brush and counterweight. First connecting plate is connected in ROFA conveying trolley body. Brush is connected in second connecting plate, and counterweight position is adjustably connected in second connecting plate, and the position of counterweight is adjusted, and the pressure of brush to track can be changed. Second connecting plate is rotatably connected in first connecting plate, and under the action of gravity, first connecting plate rotates downwardly due to the action of counterweight, makes brush contact with track, thereby can clean track. The length of tow rope is adjusted to limit the angle of second connecting plate relative to first connecting plate rotation.
