Description
Technical field
The utility model is related to the technical field of diesel engine, especially a kind of air filtration structure of diesel engine.
Background technology
See Fig. 1, the Air Filter Filter Core 1 ' of existing diesel engine is usually only with wing nut 2 ' one currently on the market
Road fixed form fastening, it is impossible to ensure do not have filtered air not enter cylinder, smoothing effect cannot ensure.It is in addition, existing
Often there is the problem of deficiency of air from both sides external air inlet in the 1 ' generally use of Air Filter Filter Core of diesel engine,
And external moisture, sundries easily enter cylinder interior from the air inlet of both sides together.
Invention content
The technical problems to be solved in the utility model is：In order to overcome the deficiencies in the prior art, a kind of bavin is provided
The air filtration structure of oil turbine, it is rational in infrastructure, ensure smoothing effect, air inflow is big, and soil resistance is good.
Technical solution is used by the utility model solves its technical problem：The air filtration structure of diesel engine,
With the air filtration bottom case that air filtration head cover, Air Filter Filter Core and inner space increase, the air filtration bottom case
It is covered with air filtering top to being installed with bolt, the Air Filter Filter Core passes through the wing nut and flange that are set on bolt
Nut twice fixed form is fixed on air filtration bottom case and is combined in the space to be formed with air filtration head cover, air filtration head cover
Bottom offer the air inlet entered for extraneous air.
Further specifically, in above-mentioned technical proposal, the air filtration bottom case passes through drawing die pressure by steel plate
It makes, air filtration head cover is formed by nylon injection-molding.
The beneficial effects of the utility model are：The air filtration structure of diesel engine provided by the utility model have with
Lower advantage：
First, Air Filter Filter Core is fixed on by the wing nut and flange nut twice fixed form being set on bolt
Air filtration bottom case is combined with air filtration head cover in the space to be formed, it is ensured that is not had filtered air not enter cylinder, is ensured
Smoothing effect；
2nd, the inner space of air filtration bottom case increases, and air inlet enters completely from bottom, and one is the increase in air inflow, and two
It is to block steam, sundries in advance, greatly reduces the inlet of steam, sundries；
3rd, air filtration bottom case is suppressed by steel plate by drawing die, and the air filtration bottom case of steel plate material can
Ensure the intensity of integrated air filtration, air filtration head cover is formed by nylon injection-molding, the air filtration head cover of nylon material
More conducively environmental protection recycling, and it is more beautiful to be molded shape.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments described in the application, for those of ordinary skill in the art, before not making the creative labor
It puts, can also be obtained according to these attached drawings other attached drawings.

Specific embodiment
The technical issues of in order to solve the utility model, technical solution and advantageous effect are more clearly understood, below
With reference to accompanying drawings and embodiments, the present invention is further described in detail.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
See Fig. 2, the air filtration structure of the diesel engine of the utility model has air filtration head cover 2, air filtration
The air filtration bottom case 1 that filter core 3 and inner space increase.Wherein, threaded hole, air filtration are offered on air filtration bottom case 1
The through-hole corresponding to the threaded hole is offered on bottom case 1.Alternatively, through-hole is offered on air filtration bottom case 1, air filtration bottom case
The threaded hole corresponding to the threaded hole is offered on 1.It, should to being installed with bolt 4 on air filtration bottom case 1 and air filtration head cover 2
Bolt 4 is threadedly coupled after passing through the corresponding through-hole in position and threaded hole with the internal thread of threaded hole.Air Filter Filter Core 3 passes through
The wing nut 5 and 6 twice fixed form of flange nut being set on bolt 4 are fixed on air filtration bottom case 1 and air filtration
In the space that the combination of head cover 2 is formed, compared with existing diesel engine air filtration structure, compress Air Filter Filter Core more than 3 and adopt
With fixing together, a flange nut 6 is added, it is ensured that do not have filtered air not enter cylinder, ensure smoothing effect.
The inner space of air filtration bottom case 1 increases, and the bottom of air filtration head cover 2 offers to be entered for extraneous air
Air inlet 2-1, air inlet completely from bottom enter, one is the increase in air inflow, second is that blocking steam, sundries in advance, subtracts significantly
The inlet of few steam, sundries.
Air filtration bottom case 1 is suppressed by steel plate by drawing die, and the air filtration bottom case 1 of steel plate material can
Ensure the intensity of integrated air filtration.Air filtration head cover 2 is formed by nylon injection-molding, the air filtration head cover of nylon material
2 are more conducive to environmental protection recycling, and it is more beautiful to be molded shape.
It is above-described, the only preferable specific embodiment of the utility model, but the scope of protection of the utility model is simultaneously
It is not limited to this, in the technical scope that any one skilled in the art discloses in the utility model, according to this reality
It is subject to equivalent substitution or change with novel technical solution and its utility model design, should all covers the protection in the utility model
Within the scope of.
