Example Embodiment

In order to facilitate the understanding of those skilled in the art, the structural principles of the present invention will be further described in detail below in conjunction with specific embodiments and drawings:
As shown in Figure 1, an anti-leakage oil supply device includes an oil supply pipe 1, an oil distribution pipe branch 2 connected to the oil supply pipe 1, and the oil supply pipe 1 is connected to an oil supply tank. The road 2 is connected with the oil supply pipeline 1 through a thread. The oil distribution pipe branch 2 is provided with a ball 3 and a stop 4, and the ball 3 is made of a material with a density lower than that of oil. The ball 3 The diameter of is 0.1~5mm smaller than the diameter of the inner wall of the branch pipe 2. The bottom of the oil distribution pipe branch 2 is a depression matched with the sphere 3. The oil supply pipeline 1 is connected with five oil distribution pipe branches 2, and the working oil volume of each oil distribution pipe branch 2 is adjustable.
The working principle of the present invention is: because the ball 3 is made of a material with a density lower than that of the oil, under normal circumstances, the hydraulic oil can flow freely in the oil distribution pipe branch 2, and the ball 3 is under the stop 4, without Will float out of the oil distribution pipe branch 2. When a leak occurs, the sphere 3 will fall into the bottom recess of the oil distribution pipe branch 2 due to the leakage of the hydraulic oil below the sphere 3. The bottom of the oil distribution pipe branch 2 is recessed to prevent further leakage.
The above content is only a preferred embodiment of the present invention, and is not intended to limit the implementation of the present invention. Appropriate variations or modifications made by those skilled in the art based on the concept of the present invention should fall within the protection scope of the present invention. Inside.
