As preferably, described capping rim is provided with the first flange and the first bearing surface, described first flange protrusions is positioned at gland one side in the radial direction at capping rim, described first bearing surface is in capping rim and is positioned at one side on gland axial direction, the hole wall of described centre bore is provided with the second flange and the 3rd flange, described lower cover forms draw-in groove between the second flange and the 3rd flange, described 3rd flange has the 3rd bearing surface towards the side of the second flange, described second flange has the second bearing surface towards the side of the 3rd flange, described first flange is arranged in draw-in groove, described first flange is arranged near the second flange, described first bearing surface is arranged near the 3rd flange, the surface of described first flange towards the second flange side and the second bearing surface close contact of the second flange, 3rd bearing surface close contact of described first bearing surface and the 3rd flange.
As preferably, described 3rd flange has the 4th flange to the second direction, flange place projection towards the side of the second flange, described 3rd bearing surface is the convex end face to second flange one end of the 4th flange.
Present invention also offers a kind of filter core, the end cover structure that this filter core adopts buckle-type as described above to connect.
Beneficial effect:
After the present invention adopts technique scheme, have the following advantages:
1. product gland and lower cover adopt buckle-type to assemble, without the need to special equipment or use welding compound;
2. simplify production technology, do not need ultrasonic equipment and special fixture, frock to weld.
