Abstract
The utility model relates to a machine oil filter, which comprises a casing and a connecting cover. A cavity is arranged in the casing, a paper core is arranged in the cavity, an upper paper core cover and a lower paper core cover are respectively arranged at the upper end and the lower end of the paper core, the connecting cover is located on one side of the upper paper core cover, an oil inlet and an oil outlet are arranged on the connecting cover, a flow guide pipe is arranged at the position in the paper core corresponding to the oil outlet, an inner sealing ring is arranged between the connecting cover and the upper paper core cover, an annular arc protrusion is arranged on one side of the connecting cover located between the oil inlet and the oil outlet in bent mode, wherein the side of the connecting cover faces to the inner sealing ring, and cambered surface seal is formed between the arc protrusion and an annular groove. By means of the technical scheme, the machine oil filter enables sealing performance between the connecting cover and the upper paper core cover to be good, and can prevent oil at the position of the oil outlet of the connecting cover from flowing back to the position of the oil inlet.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of oil filter.
Background technique
At present, existing a kind of oil filter includes housing, connecting cover; Be provided with cavity in the housing; In cavity, be provided with refill, refill upper/lower terminal and be respectively equipped with refill lid, refill lid down, connecting cover is positioned at refill and covers a side, and connecting cover is provided with filler opening, oil outlet; Corresponding oil outlet position is provided with honeycomb duct in the refill, and the oil outlet on the connecting cover is connected with the filler opening of motor.
But, the oil filter of this structure, the poor sealing between connecting cover and the last refill lid, cause easily connecting cover oil outlet place the fluid phenomenon that is back to the filler opening place take place.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology; The utility model provides a kind of oil filter; Make good seal performance between connecting cover and the last refill lid, can avoid connecting cover oil outlet place the fluid phenomenon that is back to the filler opening place take place.
The technological scheme of the utility model: a kind of oil filter; Include housing, connecting cover; Be provided with cavity in the housing, in cavity, be provided with refill, refill upper/lower terminal and be respectively equipped with refill lid, refill lid down, connecting cover is positioned at refill and covers a side; Connecting cover is provided with filler opening, oil outlet; Corresponding oil outlet position is provided with honeycomb duct in the refill, is provided with inner seal ring between described connecting cover and the last refill lid, and the connecting cover between filler opening, oil outlet is protruding to the circular arc that inner seal ring one lateral bending is provided with ring-type; Described inner seal ring is positioned at connecting cover one side and is provided with the annular groove that is complementary with the circular arc convexity, forms the cambered surface sealing between described circular arc convexity and the annular groove.
Adopt technique scheme; Through the inner seal ring that is provided with; The cambered surface sealing that the annular groove of inner seal ring and circular arc convex to form can guarantee to have enough sealing areas, can guarantee good sealing effect again; Make good seal performance between connecting cover and the last refill lid, can avoid connecting cover oil outlet place the fluid phenomenon that is back to the filler opening place take place.
The further setting of the utility model: be provided with pressure spring between the cavity bottom of described lid of refill down and housing.
Adopt above-mentioned further setting,, can be not easy to cause refill to damage phenomenon so that refill can cushion when receiving the fluid impact well through the pressure spring that is provided with.
Further being provided with again of the utility model: the cavity opening of described housing is inwardly curved to be provided with flange, and the periphery of described connecting cover is embedded between flange and the cavity inwall.
Adopt above-mentioned further setting again, the housing of this structure is connected with connecting cover, and is simple in structure, easy to process.
