[0006] In order to solve the above technical problems, the utility model provides a high stability oil seal, which comprises: a rubber layer;

[0007] The rubber layer is provided with a positioning groove on the week side, the positioning groove is internally clamped with a metal ring, the metal ring is fixedly connected with a rubber ring on the week side, the rubber ring is matched with the positioning groove, a metal framework is fixedly connected inside the rubber layer, a spring groove is formed in the inner side of the rubber layer, and a hoop spring is clamped in the spring groove.

[0008] Preferably, the rubber layer is fixedly connected with an inner ring at the upper end, and the rubber layer is fixedly connected with an outer ring at the upper end.

[0009] Preferably, the rubber layer is fixedly connected with a circular hole at the upper end, and the circular hole is provided with multiple groups, and the circular hole is fixedly connected with the inner ring and the outer ring.

[0010] Preferably, a circular hole is formed through the front surface of the connecting block, a reinforcing block is fixedly connected at the bottom of the circular hole, and the reinforcing block is fixedly connected with the metal framework.

[0011] Preferably, the rubber layer is provided with rubber sheets at the upper end, and the rubber sheets are provided with multiple groups, and the rubber sheets are clamped between the inner ring and the outer ring.

[0012] Preferably, a plug hole is formed at the upper end of the rubber sheet, and the plug hole is provided with two groups.

[0013] Compared with related technologies, the oil seal with high stability provided by this utility model has the following beneficial effects:

[0014] This invention provides a highly stable oil seal. Before installation, the metal ring and rubber ring are inserted into the positioning groove, and then the oil seal is installed and used. During installation, the mounting groove will squeeze the rubber ring, and the rubber ring will deform under the pressure and fit tightly against the mounting point. At this time, the elasticity of the rubber ring can seal the mounting point. Even if oil leaks from the periphery of the rubber layer, it will be blocked by the rubber ring. This oil seal is not easy to leak and has high stability. When removing the oil seal from the mounting point, an iron hook can be inserted into the insertion hole to hook out the rubber sheet, and then the iron hook can be inserted into the round hole. At this time, the connecting block can be pulled by the iron hook to easily pull out the oil seal. This structure makes it very easy to remove the oil seal. Attached Figure Description
