Description

Technical Field

[0001] The utility model relates to the technical field of outboard motor waterproofing, in particular to a waterproof outboard motor lifting device. Background Art

[0002] The waterproof outboard motor tilting device is a device used to control the angle between the propeller shaft and the water surface. During sailing, when it is necessary to adapt to different water conditions, the propeller shaft can be turned up or down by controlling the tilting device, which is called "outward tilt" or "inward tilt" respectively.

[0003] According to the Chinese patent CN202121478818.6, in the application, the lifting action of the outboard motor is driven by controlling the lifting frame through the lifting hydraulic rod, which can avoid manual direct handling of the outboard motor. At the same time, the device can also fix the lifted outboard motor on the boat, which is convenient for direct use next time. This not only improves work efficiency, but also reduces the labor intensity of manual labor;

[0004] Although the hydraulic rod in the application can effectively solve the problem of the outboard motor being heavy and inconvenient to use, when in use, since the outboard motor is fixed with a rotating threaded rod to fix the outboard motor lifting device, the threaded rod will be exposed to the outside. When corroded by water, salt and other environmental factors, the threaded rod will cause wear of the threaded rod. When the threaded rod is rusted, it will not only reduce its strength, but also may cause thread failure, making it impossible to correctly fix the outboard motor or adjust the lifting angle. For this reason, we propose a waterproof outboard motor lifting device. Utility Model Content
