[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] See also Figure 1-4 , the utility model implements 1 example to provide a leakage-proof lubricating oil cup, including an oil cup body 1 installed on an oil cup base 2, an oil filling channel 21 is provided on the oil cup base 2, the oil filling channel 21 is connected to the machine pump oil chamber 4 through an oil filling pipe 3, an oil filling cylinder 6 which can extend into the oil filling channel 21 is provided at the lower end of the oil cup body 1, an oil outlet 61 is provided at the lower end of the oil filling cylinder 6, a steel ball 8 is provided in the oil filling cylinder 6, a spring 7 for pressing the steel ball 8 at the oil outlet 61 is provided between the steel ball 8 and the top of the oil filling cylinder 6, one end of the spring 7 is fixedly connected to the steel ball 8, and the other end is fixedly connected to the top of the oil filling cylinder 6, a plurality of oil inlet holes 62 are provided on the outer wall of the oil filling cylinder 6 located in the oil cup body 1, and a thimble is provided in the oil filling channel 21 to lift the steel ball 8 so as to realize the lubricating oil flowing out of the oil outlet 61.

[0023] Among them, the upper end of the oil filling cylinder 6 is closed, and multiple oil inlet holes 62 are evenly distributed along the circumference of the oil filling cylinder 6. Multiple oil inlet holes 62 can also be set at the upper end of the oil filling cylinder 6. The oil cup body 1 is made of transparent glass, and there is a scale on one side of the oil cup body 1.

[0024] Specifically, the ejector pin includes a conical mesh cover 9, which is provided with mesh holes for lubricating oil to pass through, with the small end of the mesh cover 9 facing upward and the large end facing downward, the small end diameter of the mesh cover 9 is smaller than the diameter of the oil outlet 61, and the large end diameter of the mesh cover 9 is larger than the diameter of the oil outlet 61. After the oil cup body 1 is installed on the oil cup base 2, the oil filling cylinder 6 extends into the oil filling channel 21, and the small end of the mesh cover 9 extends into the oil filling cylinder 6 through the oil outlet 61, and contacts and lifts the steel ball 8. The lubricating oil in the oil cup body 1 enters the oil filling cylinder 6 from the oil inlet through hole 62, then flows out through the oil outlet 61, enters the oil filling channel 21 through the mesh holes on the mesh cover 9, and then enters the pump oil chamber 4 through the oil filling pipe 3. It should also be noted that the parts not described in detail in this application are all prior art.

[0025] In addition, a recessed groove cooperating with the oil cup body 1 is provided on the oil cup base 2, and the recessed groove is circular. The oil filling channel 21 is arranged at the center of the recessed groove, and a locking bolt 5 for locking the oil cup body 1 is provided on the outer wall of the oil cup base 2. By setting the locking bolt 5 to lock the oil cup body 1, the stability of the oil filling is ensured.

[0026] When it is necessary to add oil to the oil cup body 1, the oil filling cylinder 6 of the oil cup body 1 is facing upwards, the filling pipe is brought into contact with the ball 8, the ball 8 moves toward the inside of the oil filling cylinder 6, the front end of the filling pipe is extended into the oil filling cylinder 6 through the oil outlet 61, and then refueling is carried out. After refueling is completed, the filling pipe can be pulled out.

[0027] When the oil cup body 1 is flipped and installed on the oil cup base 2, the steel ball 8 is pressed against the oil outlet 61 under the action of the spring 7, thereby effectively preventing the lubricating oil from spilling from the oil outlet 31 during flipping; when the oil cup body 1 is installed on the oil cup base 2, the mesh cover 9 lifts the steel ball 8, and the lubricating oil flows into the oil filling channel 21 through the oil outlet 61 and the mesh cover 9 in turn, and then flows into the machine pump oil chamber 4 through the oil filling pipe 3, which is convenient and fast to operate and has strong flexibility.

The upper end of the limiting sleeve 63 is fixedly connected to the top of the oil filling cylinder 6, and the lower end of the limiting sleeve 63 does not contact the bottom of the oil filling cylinder 6. The outer diameter of the limiting sleeve 63 is smaller than the inner diameter of the oil filling cylinder 6, and a plurality of flow holes for the passage of lubricating oil are evenly distributed on the limiting sleeve 63. By setting the limiting sleeve 63, the straightness of the up and down movement of the steel ball 8 is guaranteed, so that the steel ball 8 can be better pressed at the oil outlet 61.

[0030] For example, in implementation 3, unlike the implementation described above, a rubber pad is provided on the outer wall of the steel ball 8. By providing a rubber pad on the outer wall of the steel ball 8, the sealing effect between the steel ball 8 and the oil outlet is improved, further preventing the lubricating oil from spilling.
