Specific embodiment

The utility model is described further with reference to the accompanying drawing.

A kind of filter element connection clamp, as shown in Figures 1 to 9, including filter core bayonet end cap 1 and filter housing bayonet connection Part 2, the filter core bayonet end cap 1 include connection clamp 11, boss shell 12 and lantern ring 13；The connection clamp 11 is that both ends are penetrating Cylinder-like structure, top side, which is peripherally and outwardly extended, forms annular protrusion 111,111 surface of annular protrusion close to top The side at end is uniformly fixed with the arc raised line 1111 that several are in " 7 " font.

The boss shell 12 is the penetrating cyclic structure in both ends, and sealing socket is fixed on connection 11 lower part of clamp On side wall.

13 outer wall of lantern ring is regular polygon, and inner wall is circle, and the lantern ring 13 is rotationally nested in described convex On 11 side wall of connection clamp between platform shell 12 and annular protrusion 111, and outside 13 internal diameter of the lantern ring and the connection clamp 11 Diameter is adapted.

The filter housing bayonet connection 2 is the penetrating cyclic structure in both ends, and the inner sidewall of its underpart is and the lantern ring 13 The inner sidewall of the compatible regular polygon structure of outer wall, upper part is circular configuration, and is uniformly fixed in its circular inner sidewall Several arc strips 21 compatible with the arc raised line 1111, the filter housing bayonet connection 2 are socketed in the filter core On bayonet end cap 1, its underpart regular polygon inner sidewall fastens with 13 outer wall of lantern ring, and by rotating the filter housing bayonet Connector 2 drives the arc strip 21 and the arc raised line 1111 inconsistent, and the arc strip 21 is convex by the arc Item 1111 limits.

When in use, the lower end of filter core bayonet end cap 1 is fixed with one end of filter core, specifically, one end of filter core is supported It touches and is fixed on boss shell 12, so that connection clamp 11 is connected with filter core, filter housing bayonet connection 2 is fixed on filter housing (i.e. Filter) one end pass through arc on connection clamp 11 when filter core bayonet end cap 1 and filter housing bayonet connection 2 are connected and fixed The setting of arc strip 21 on raised line 1111 and filter housing bayonet connection 2, so that filter housing bayonet connection 2 and filter core bayonet end cap After 1 mutually fastens and relative rotation, contradicting arc strip 21 and arc raised line 1111 mutually can be completed filter housing bayonet connection Connection, fixed work between part 2 and filter core bayonet end cap 1, process is simply, conveniently.

In the present embodiment, axially spaced-apart is fixed with several the first grooves 131 on 13 inner wall of lantern ring, with the set The outer wall of the corresponding connection clamp 11 of ring 13 is equipped with first raised line 112 compatible with first groove 131, this Sample setting can prevent lantern ring 13 from arbitrarily rotating on connection clamp 11, and then when filter housing bayonet connection 2 and filter core bayonet end cap After 1 is connected and fixed, enable to relatively rotate easily between filter housing bayonet connection 2 and connection clamp 11, thus Ensure that filter core bayonet end cap 1 and filter housing bayonet connection 2 be connected and fixed after the phenomenon that being not in loosening.

In the present embodiment, the filter core bayonet end cap 1 and filter housing bayonet connection 2 are that plastic material is made, in this way It may make this connection clamp not get rusty, be conducive to be used for a long time.

In the present embodiment, the quantity of the arc strip 21 is equal with the quantity of the arc raised line 1111, in this way may be used It is more firm to make to be connected and fixed between filter core bayonet end cap 1 and filter housing bayonet connection 2.

Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered It is defined by the claims.
