[0020] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4This is an embodiment of the present utility model, a leakable high-pressure oil cup, including a bottom column 1, a top column 2 is provided on the top of the bottom column 1, and a threaded hole 3 is opened on the top of the top column 2, and the internal thread of the threaded hole 3 is connected to a threaded column 4, and a bottom rod 5 is provided at the bottom of the threaded column 4, and a cavity 6 with a diameter larger than the threaded hole 3 is opened inside the top column 2, and an elastic component 7 for pressure relief is sleeved inside the cavity 6.

[0022] The specific problem addressed by this specific embodiment is to solve the problem that the inability to relieve pressure on the shaft body will increase the maintenance process and lead to increased costs. The utility model utilizes the setting of the elastic component 7. When the shaft body needs to be maintained, it is only necessary to rotate the threaded column 4 so that the threaded column 4 drives the bottom rod 5 to move downward, thereby causing the bottom rod 5 to touch the ball 71. As the downward movement continues, the ball 71 compresses the spring 72, thereby causing the ball 71 to move away from the bottom end of the threaded hole 3, thereby exposing the oil drain hole 8 on one side of the bottom end of the inner wall of the threaded hole 3. The oil will flow out of the oil drain hole 8 along the pressure relief chamber inside the bottom column 1 and the cavity 6 inside the top column 2, completing the oil and pressure relief, thereby facilitating the maintenance and installation of the shaft body, shortening the maintenance process, and improving maintenance efficiency.

[0023] The elastic component 7 includes a sphere 71 that is sleeved inside the cavity 6, and a spring 72 is provided at the bottom of the sphere 71. In this specific embodiment, a pressure relief chamber is opened inside the bottom column 1, and the aperture of the pressure relief chamber is larger than the diameter of the spring 72. An oil drain hole 8 is opened on one side of the top of the top column 2, and one end of the oil drain hole 8 is connected to the bottom end of the inner wall of the threaded hole 3. The diameter of the sphere 71 is larger than the diameter of the bottom of the threaded hole 3, and the diameter of the sphere 71 is smaller than the diameter of the cavity 6. When the shaft needs to be maintained, it is only necessary to rotate the threaded column 4 so that the threaded column 4 drives the bottom rod 5 to move downward, thereby causing the bottom rod 5 to touch the ball 71. As it continues to move downward, the ball 71 compresses the spring 72, thereby causing the ball 71 to move away from the bottom end of the threaded hole 3, thereby exposing the oil drain hole 8 on one side of the bottom end of the inner wall of the threaded hole 3, and the oil will flow out of the oil drain hole 8 along the pressure relief cavity inside the bottom column 1 and the cavity 6 inside the top column 2, completing the oil and pressure relief, thereby facilitating the maintenance and installation of the shaft, shortening the maintenance process, and improving maintenance efficiency.

[0024] In this specific embodiment, the diameter of the cavity 6 is larger than the diameter of the bottom of the threaded hole 3, and the diameter of the cavity 6 is the same as the diameter of the pressure relief chamber. A knob is provided on the top of the threaded column 4, and a hexagonal groove is provided at the bottom of the knob.

[0025] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
