[0014] Through the above technical scheme, the sealing effect can be achieved.

[0015] Further, the scraping ring is slidably sleeved on the outer wall of the filter cotton.

[0016] Through the above technical scheme, the particles on the outer wall of the filter cotton can be cleaned.

[0017] Further, the sealing ring is made of silicone rubber and has high temperature resistance and aging resistance.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model discloses a hydraulic filter element convenient to replace, adopts the form of split type combination, is connected through the threaded connection between nut and threaded rod, can make the disassembly between scraping ring and hydraulic filter element more simple and convenient under the auxiliary effect of limiting block, is provided with spring on the outer wall of threaded rod, when the oil tank cover is opened, the circular ring will automatically rise by the elastic force of spring, thereby facilitating the operator to take out the hydraulic filter element from the oil tank, thereby making the replacement more simple.

[0020] 2. The utility model discloses a hydraulic filter element convenient to replace, under the mutual cooperation of threaded rod, limiting block, spring, connecting rod, circular ring and magnetic block, through repeatedly pressing magnetic block and circular ring, the particles on the surface of filter cotton can be cleaned by scraping ring, thereby making the hydraulic filter element reusable, thereby greatly improving the practicability of the hydraulic filter element.
