[0001] This utility model relates to the field of lubrication equipment technology, and in particular to an automatic grease filling cup. Background Technology

[0002] In modern production activities, equipment lubrication is crucial. Good lubrication can reduce equipment wear, lower noise, and extend equipment life.

[0003] In operations where various equipment requires lubrication, the operation mainly relies on manual inspection. When abnormal noises or insufficient oil are found, lubrication is manually added. Due to the limitations of manual inspection, it is possible to fail to detect insufficient oil in time, which leads to poor lubrication of the equipment. In addition, manual adding requires stopping the machine, which poses a high risk of grease contamination.

[0004] Therefore, in order to avoid the need for manual inspection and lubrication, this design proposes an automatic grease filling cup. Summary of the Invention

The connection between the spring-loaded part and the cup cover 2 is provided with a locking part for fixing the spring-loaded part.

[0037] Specifically, the top outer side of the oil cup body 1 is provided with a cup body connecting thread 102, which is used to thread the cup lid 2. The inner wall of the cup lid 2 is provided with a thread corresponding to the cup body connecting thread 102.

[0038] Furthermore, the moving part includes the piston 4 and the piston seal ring 3;

[0039] It should be noted that the oil pusher piston 4 is located in the inner cavity of the oil cup body 1, and the piston sealing ring 3 is sleeved on the outer side of the oil pusher piston 4.

[0040] Specifically, the oil piston 4 and the piston seal ring 3 are fixed together with glue. The piston seal ring 3 is made of rubber and is in close contact with the inner wall of the oil cup body 1.

[0041] It should be noted that the springback section includes a connecting plate 6 and a compression spring 7;

[0042] Specifically, the connecting plate 6 is located on the side of the oil-pushing piston 4 near the cup lid 2, and multiple compression springs 7 are arranged around the connecting plate 6 on the side near the cup lid 2. The end of the compression spring 7 away from the connecting plate 6 is located at the bottom of the locking part.

[0043] It should be noted that the connecting plate 6 and the oil piston 4 are glued together and fixed. The connecting plate 6 is made of stainless steel and the end of the connecting plate 6 is welded to the compression spring 7. Example 2

[0044] A locking part is applied to the automatic grease filling cup in Embodiment 1;

[0045] Specifically, the locking part includes a connecting sleeve 8, an elastic lever 9, and a snap-fit ​​protrusion 901;

[0046] It should be noted that the connecting sleeve 8 is set in the inner cavity of the cup lid 2, the end of the compression spring 7 is fixedly connected to the side of the connecting sleeve 8, multiple elastic paddles 9 are symmetrically arranged at the bottom of the connecting sleeve 8, the snap-fit ​​protrusion 901 is set on the side of the elastic paddle 9, and the side of the snap-fit ​​protrusion 901 is inserted and connected to the inner wall of the cup lid 2.
