The utility model provides a night search and rescue lighting device of a rescue helicopter, and belongs to the technical field of lighting devices. Comprising an illuminating lamp; the horizontal vibration reduction assembly is arranged at the top of the illuminating lamp and comprises a base arranged at the top of the illuminating lamp, a connecting shaft is arranged between the base and the illuminating lamp, the connecting shaft is fixedly connected with the illuminating lamp, and a transmission plate is fixedly connected to the end, close to the interior of the base, of the connecting shaft; a main elastic piece is arranged on the side, close to the transmission plate, of the base. By arranging the horizontal vibration reduction assembly, when the illuminating lamp is disturbed by airflow, the connecting shaft swings along with the illuminating lamp, then the transmission plate is driven to move in the base, the acting force borne by the transmission plate is transmitted to the main elastic pieces, and the multiple main elastic pieces can conduct vibration reduction by means of elastic deformation of the main elastic pieces. The vibration energy can be effectively absorbed and buffered from multiple directions, the influence of vibration in the horizontal direction on the lighting device is remarkably reduced, and the service life of the lighting device can be prolonged.

The application discloses a kind of gas magnetization energy-saving devices, it is related to magnetization energy-saving device technical field, the gas magnetization energy-saving device, including magnetization equipment body, magnetization equipment body includes front shell, rear shell and gas flow pipe, front shell and rear shell are set in front and back two sides of gas flow pipe, the outer surface of front shell and rear shell is fixedly connected with mounting block, the outer surface of gas flow pipe is fixedly connected with two symmetrical first fixed blocks, the top of gas flow pipe is provided with gas pipe, the gas magnetization energy-saving device, by making gear drive fixed rod slide out the inside of fixed groove, so that the fixation of gas flow pipe and gas pipe is removed, so that the connection of gas flow pipe and gas pipe is more convenient, and staff can more smoothly install and disassemble magnetization equipment body, so that staff can conveniently carry out post-maintenance to magnetization equipment body, simultaneously, staff can more conveniently use device.

The utility model relates to the technical field of structural sealing, in particular to a high-speed oil seal for forward and reverse rotation of a shaft body, which comprises an elastic sealing body, an inner bone ring plate, a reverse elastic ring plate and a forward elastic ring plate, the reverse elastic ring plate and the forward elastic ring plate are both arranged on the inner side of the inner bone ring plate, the reverse elastic ring plate and the forward elastic ring plate are both used for being arranged on the shaft body in a sleeving mode, and an oil storage cavity is formed among the reverse elastic ring plate, the forward elastic ring plate and the shaft body. A reverse spiral groove clockwise around the axis direction of the shaft body is formed in the reverse elastic ring plate, a forward spiral groove anticlockwise around the axis direction of the shaft body is formed in the forward elastic ring plate, and the reverse spiral groove and the forward spiral groove are both attached to the outer side wall of the shaft body.
