Please refer to Fig. 1 to Fig. 5, be one better embodiment of the utility model oil filter, including cover assembly 10, The filter assemblies 20 of cover assembly 10 are abutted, the overflow assemblies 30 of filter assemblies 20 is abutted and is arranged filter assemblies 20 and overflow The casing assembly 40 of component.One end of overflow assemblies 30 wears the inside for protruding into filter assemblies 20, and the other end abuts the shell The inner surface of component 30.

The cover assembly 10 includes upper end cover 11, the cuff 12 for being installed on 11 one end of upper end cover and connection upper end cover 11 Non-return set 13 and the adapter 14 of the other end；Non-return set 13 is located between upper end cover 11 and adapter 14.Upper end cover 11 includes The panel 111 of roughly annular setting and the middle shaft part 112 extended downwardly from 111 inner peripheral of panel.Cuff 12 is installed on face On plate 111, for connecting cover assembly 10 and casing assembly 40.In the present embodiment, uniform intervals are set on the periphery of panel 111 There are several fuel feed holes 113.Non-return set 13 is sheathed on middle shaft part 112, and the flank of non-return set 13 blocks fuel feed hole 113.Adapter 14 one end is arranged middle shaft part 112, and the other end is used to abut one end of filter assemblies 20.Further, in the present embodiment, on Cap assemblies 10 further include the sealing ring 15 for being connected to cuff 12 backwards to 11 one side of upper end cover, and when installation, sealing ring 15 is located in Between end cap 11 and engine, to enhance leakproofness.

The filter assemblies 20 include the skeleton 21 of cylindrical setting, the shaft 22 being connected in skeleton 21, cover respectively If the torsional spring 23 of 22 opposite end of shaft, the filter plate 24 for connecting torsional spring 23, several limited blocks being connected on 21 inner surface of skeleton 25 and it is sheathed on the filtering layer 26 of 21 outer surface of skeleton.The inside of the inside connection middle shaft part 112 of skeleton 21, the surface of skeleton 21 Uniform intervals are equipped with several through-holes 210, and the machine oil convenient for filtering through filter layer 25 enters the inside of skeleton 21, then passes through middle shaft part 112 flow to engine.Shaft 22 is connected radially to the inside of skeleton 21.On the inner surface of one end connecting framework 21 of torsional spring 23, The other end connects filter plate 24, so that the radial direction of filter plate 24 and the radial direction of skeleton 21 are mutually perpendicular to without under external force, filtering 24 is not It is filtered.In the present embodiment, the rounded setting of filter plate 24, the diameter of filter plate 24 correspond to the internal diameter of skeleton 21；Filter plate 24 is equal It is even to be equipped at intervals with several filter openings 240, it can effectively filter the impurity in machine oil.In the present embodiment, the quantity of limited block 25 is two, Two limited blocks 25 are set to the opposite end on 21 inner surface radial direction direction of skeleton, for limiting after overturning to filter plate 24 Position.

The overflow assemblies 30 include fixing seat 31, wear fixing seat 31 moving valve 32, be connected to 32 one end of moving valve Mandril 33, be connected to the lock ring 34 of 32 other end of moving valve and be located between fixing seat 31 and lock ring 34 first elasticity Part 35.In the present embodiment, the setting substantially in the shape of a " convex " of fixing seat 31, as shown in figure 4, the lug boss pair of 31 one end of fixing seat The inside of skeleton 21 should be protruded into, the other end abuts skeleton 21.Fixing seat 31 is equipped with the through hole 310 of rounded setting, this runs through The upper and lower ends of fixing seat 31 are run through in hole 310, to accommodate wearing for moving valve 32.Moving valve 32 includes the activity of rounded setting Valve body 321 and it is connected to locking pin 322 of the movable valve body 321 far from 33 one end of mandril.The outer diameter of movable valve body 321 Greater than the diameter of through hole 310, when assembling, movable valve body 321 abuts fixing seat 31, after locking pin 322 wears through hole 310 It is mutually buckled with lock ring 34, forms locking.Further, in the present embodiment, lock ring 34 is square cyclic annular setting, lock ring 34 The catercorner length of outer ring is greater than the diameter of through hole 310, so that one end of the moving valve 32 after locking is limited in fixing seat 31 One end.

Referring to Fig. 3 to Fig. 5, in the present embodiment, one end of mandril 33 is equipped with lozenges 331, as shown in figure 5, The periphery of the corresponding filter plate 24 of the lozenges 331.It is separate that mandril 33 far from one end of lozenges 331 is connected to movable valve body 321 In the one side of locking pin 322.When filtering layer 26 blocks, machine oil washes moving valve 32 open, and moving valve 32 is transported towards 24 direction of filter plate Dynamic, the lozenges of mandril 33 stirs filter plate 24, and filter plate 24 flips an angle, and then under the action of oil pressure, filter plate 24 overcomes The torque of torsional spring 23 is directly overturn, and filter plate 24 abuts limited block 25, at this time the radial phase of the radial direction of filter plate 24 and skeleton 21 It is mutually parallel.Machine oil is filtered by the filter opening 240 on filter plate 24, can effectively be filtered out the impurity in machine oil, be improved machine oil Degree of purity.Compared with traditional oil filter, mostly filtering ensures the oil filter of the utility model together, filter effect It is good.

The casing assembly 40 includes shell 41 and the second elastic component 42 being installed in shell 41.One end of shell 41 It is arranged in opening, shell 41 accommodates one end of overflow assemblies 30, filter assemblies 20 and cover assembly 10, and shell 41 connects cuff 12, one end of shell 41 is blocked, so that the inside of shell 41 forms sealed environment.One end of second elastic component 42 is connected to shell The inner surface of body 41, the other end abut fixing seat 31.

In the present embodiment, the first elastic component 35 and the second elastic component 42 are spring；In other embodiments, first Elastic component 35, the second elastic component 42 can also be elastic slice, cylinder or it is other with the elasticity of compression setting device, can play with It is similarly acted in the present embodiment.

Said engine oil filter, structure is simple, and rationally, torsional spring 23 and filter plate 24, filtering layer is arranged in design inside skeleton 21 26 when not blocking, and filter plate 24 is not filtered machine oil；When 26 blocking is rubbed in filter, machine oil washes moving valve 32,32 court of moving valve open It is moved to 24 direction of filter plate, mandril 33 overturns filter plate 24, and filter plate 24 overcomes the torque of torsional spring 23 complete under the impact of machine oil Overturning, is filtered machine oil, can effectively filter out impurity, improve the degree of purity of machine oil, filter effect is good, and can effectively extend makes Use the service life.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
