Anti-loose oil collecting bottle for wind driven generator

The anti-loosening oil collecting bottle comprises an oil collecting bottle body, an anti-loosening bottle cap is connected to the upper end of the oil collecting bottle body, a connecting bottle opening is integrally connected to the upper end of the oil collecting bottle body, a plurality of protrusions are arranged on the outer surface of the connecting bottle opening in a surrounding mode, and the anti-loosening bottle cap comprises a round cap. The lower end of the round cover is integrally connected with a plurality of clamping blocks. The vibration effect of the wind driven generator in the working process is strong, waste grease enables the round cover and the connecting bottle opening which are in threaded connection to be loosen, therefore, the round cover can be prevented from being separated from the oil collecting bottle through the arrangement of the clamping block and the protrusion, damage to the wind driven generator is avoided, the peripheral corners of the protrusion and the clamping block
