Snap connection between the hole wall in heart hole.
Preferably, described capping rim is provided with the first flange and the first bearing surface, described first flange protrusions are in gland
Edge is located at gland one side in the radial direction, and described first bearing surface is in that capping rim is located on gland axial direction
Face, the hole wall of described centre bore is provided with the second flange and third lip, and described lower cover is between the second flange and third lip
Form draw-in groove, described third lip has the 3rd bearing surface towards the side of the second flange, and described second flange is convex towards the 3rd
The side of edge has the second bearing surface, and described first flange is located in draw-in groove, and described first flange is arranged near the second flange, institute
State the first bearing surface to arrange near third lip, described first flange towards the second flange side surface and the second flange the
Two bearing surfaces are in close contact, and described first bearing surface is in close contact with the 3rd bearing surface of third lip.
Preferably, described third lip towards the second flange side have to the second flange place direction raised the
Four flanges, described 3rd bearing surface is the end face that the 4th flange is convex to second flange one end.
Present invention also offers a kind of filter element, the end cover structure that this filter element is connected using buckle-type as described above.
Beneficial effect：
After the present invention adopts technique scheme, there is advantages below：
1. product gland and lower cover adopt buckle-type to assemble, without special equipment or use welding compound；
2. simplify production technology, be not required to ultrasonic equipment and special fixture, frock are welded.

Fig. 4 show the structural representation of lower cover in the end cover of filter element structure of the connection of buckle-type shown in Fig. 2.
Specific embodiment
It is illustrated in figure 1 the preferred embodiment of filter element of the present invention, this filter element includes lid 1, lower cover 4, filter paper 2, central canal 3
With gland 5, filter paper 2 surrounds a circulus, and the upper end of this circulus is connected with upper lid 1, lower end and lower cover 4 connect
Connect, upper lid 1, lower cover 4 adopt the modes such as bonding with the connected mode of filter paper 2, and lower cover 4 has centre bore, and gland 5 is assemblied in center
Snap connection between Kong Zhong, and gland 5 edge and the hole wall of centre bore, gland 5 center is provided with through hole 54, gland 5 is towards upper
Cover 1 one side surfaces and form annular protrusions 53, through hole 54 be located at circularize raised 53 surround in the range of, central canal 3 is located at filter paper 2
Inside the circulus being surrounded, 1 assembly connection is covered with upper in the upper end of central canal 3, and annular protrusion 53 is stretched in the lower end of central canal 3
Snap connection between inside and annular protrusion 53, and inside annular protrusion 53, between central canal 3 and gland 5, pass through O-ring
6 cooperations.
In this embodiment, it is illustrated in figure 2 the end cover of filter element structure of buckle-type connection, be illustrated in figure 3 buckle shown in Fig. 2
The structural representation of gland 5 in the end cover of filter element structure that formula connects, is illustrated in figure 4 the filter element end of the connection of buckle-type shown in Fig. 2
The structural representation of lower cover 4 in lid structure, in this structure, gland 5 edge is provided with the first flange 51 and the first bearing surface 52, and first
Flange 51 projection is located at gland 5 one side in the radial direction at gland 5 edge, and the first bearing surface 52 is in gland 5 edge and is located at
One side on gland 5 axial direction, the hole wall of centre bore is provided with the second flange 41 and third lip 42, and lower cover 4 is convex second
Form draw-in groove, third lip 42 has to the second flange 41 institute towards the side of the second flange 41 between edge 41 and third lip 42
In the 4th flange 43 that direction is raised, the end face that the 4th flange 43 is convex to the second flange 41 one end forms the 3rd bearing surface 44, the
