Third locking portion is adapted with the side wall profile of reinforcing rib, when end cap relative to cylinder part by relatively rotating When twisting resistance, third locking portion firmly " is blocked end cap " by reinforcing rib, makes its junction with cylinder part not because of torsion External force and occur to loosen and then lead to seal failure.

As a preferred embodiment of the above technical solution, the reinforcing rib is wholely set with the convex block, and by the outer of the convex block Contour extension is enclosed to come out.

As a preferred embodiment of the above technical solution, the through-hole passed through for the crimp is additionally provided in the arc spacer.

As a preferred embodiment of the above technical solution, the manipulation portion is an annulus, and the lower part of the annulus is provided with pressure Portion, the lower surface of the pressure unit are plane.

As a preferred embodiment of the above technical solution, the end cap and the cylinder part are formed at connection structure is superimposed on one The boss risen is provided with protrusion compatible with the profile of the boss on the first locking portion.

In conclusion the utility model has the following beneficial effects:

The application provide it is a kind of include arc spacer filter end cover attaching structure, the end for water treatment filter Lid connection is provided with the hard gasket of an abnormity, by pressure dissipation to the connection of entire end cap between crimp and end cap Place, enhances the sealing stability at each position, while enhancing the structural strength of crimp junction, adapts filter to high pressure The running environment of power.
