Description
Technical field
The utility model relates to automobile filter technical field, particularly a kind of filter paper core fixed structure of rotary filter.
Background technique
Automobile rotary filter is arranged in engine lubrication system.Its upstream is oil pump, and downstream is each component needing in motor to lubricate.The effect of rotary filter carries out filtering to from objectionable impurities in the machine oil of oil sump, with the kinematic pair such as engine oil supplying bent axle, connecting rod, camshaft, pressurized machine, piston ring of cleaning, play lubrication, cooling, cleaning action, thus extend the life-span of these component.After the refill lid of existing rotary filter and filter paper core are assembled, filter paper core often can produce off normal phenomenon in filter cleaner, affects product performance.Therefore be necessary to improve further the fixed structure of existing filter paper core.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, the filter paper core fixed structure of rotary filter reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
The filter paper core fixed structure of a kind of rotary filter described in the utility model, comprises center webmaster and filter paper core, and the outer wall of described center webmaster is provided with raised line and several through holes, and the side that through hole is positioned at raised line is arranged; The inner hole wall of described filter paper core is provided with the groove matched mutually with raised line; Described center webmaster is nested in filter paper core endoporus, and is mutually fastened by raised line and groove and realize being fixedly connected with of center webmaster and filter paper core; The upper-end surface of described filter paper core is covered with refill upper cover, and the tegmental wall annular of described refill upper cover is provided with several upper lug; The lower end surface of described filter paper core is covered with refill lower cover, and the tegmental wall annular of described refill lower cover is provided with several lower lugs.
Further, the quantity of described upper lug is four; Upper lug is made up of oblique side wall sections and straight sidewall section, and the upper angle between the sidewall of oblique side wall sections and horizontal line is 45 degree.
Further, the quantity of described lower lug is four; Lower angle between the sidewall of lower lug and horizontal line is 63 degree.
Further, described raised line is arranged in the shape of a spiral.
After adopting said structure, the utility model beneficial effect is: arrange multiple lug by covering at refill, considerably reduce the gap between shell and filter paper core, lug is made to play positioning and guiding effect, effectively can prevent the filter paper core off normal phenomenon in product, thus the strainability ensureing product further and the scrap of producing because of filter paper core off normal.It is simple that the utility model has structure, arranges rationally, the advantages such as fabricating cost is low.

Description of reference numerals:
1, refill upper cover; 11, upper lug; 2, center webmaster; 21, raised line; 22, through hole; 3, filter paper core; 31, groove; 4, refill lower cover; 41, lower lug; α, upper angle; β, lower angle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, the filter paper core fixed structure of a kind of rotary filter described in the utility model, comprise center webmaster 2 and filter paper core 3, the outer wall of described center webmaster 2 is provided with raised line 21 and several through holes 22, and the side that through hole 22 is positioned at raised line 21 is arranged; The inner hole wall of described filter paper core 3 is provided with the groove 31 matched mutually with raised line 21; Described center webmaster 2 is nested in filter paper core 3 endoporus, and is mutually fastened by raised line 21 and groove 31 and realize being fixedly connected with of center webmaster 2 and filter paper core 3.
The upper-end surface of described filter paper core 3 is covered with refill upper cover 1, and the tegmental wall annular of described refill upper cover 1 is provided with several upper lug 11; The lower end surface of described filter paper core 3 is covered with refill lower cover 4, and the tegmental wall annular of described refill lower cover 4 is provided with several lower lugs 41.
Further, the quantity of described upper lug 11 is four; Upper lug 11 is made up of oblique side wall sections and straight sidewall section, and the upper angle α between the sidewall of oblique side wall sections and horizontal line is 45 degree.
Further, the quantity of described lower lug 41 is four; Lower angle β between the sidewall of lower lug 41 and horizontal line is 63 degree.
Further, described raised line 21 is arranged in the shape of a spiral.
The utility model beneficial effect is: arrange multiple lug by covering at refill, considerably reduce the gap between shell and filter paper core, lug is made to play positioning and guiding effect, effectively can prevent the filter paper core generation off normal phenomenon in product, thus ensure the strainability of product further and reduce the scrap of producing because of filter paper core off normal.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
