Abstract
A kind of oil filter for preventing from dismantling oil leak, including housing, the filter core sub-unit that is arranged in housing, are characterized in that：The housing is tubular structure of the front end in circular arc Shape closed, and support spring is provided between housing and filter core sub-unit, and housing bottom is screwed with thread seal plate, and thread seal plate is provided with body seal, check-valves is provided between thread seal plate and filter core sub-unit.It has the low advantage of low simple and compact for structure, convenient to use, maintenance cost, long service life, fault rate.
Description
Technical field
The utility model is related to automobile manufacturing field, specifically a kind of oil filter for preventing from dismantling oil leak.
Background technology
, it is necessary to change oil filter during the time-based maintenance of automobile engine, engine scuffing is reduced, extension is started
The machine life-span.Traditional oil filter, with paper as filter core, metal shell is made, and is dismantled when being conveniently replaceable, installed.Due to
There is more machine oil in oil filter, when old oil filter is dismantled, its internal machine oil can be flowed out by oil-out, right
Environment is polluted, while causing potential safety hazard to staff.Existing oil filter check-valves only can guarantee that internal machine oil
Cannot be flowed out from oil inlet.
Utility model content
The purpose of this utility model is to provide a kind of oil filter for preventing from dismantling oil leak, fundamentally solves above-mentioned
Problem, it has the low advantage of low simple and compact for structure, convenient to use, maintenance cost, long service life, fault rate.
To achieve the above object, the utility model provides following technical scheme：This prevents from dismantling the oil filtration of oil leak
Device includes housing, the filter core sub-unit being arranged in housing, is characterized in that：The housing is front end in circular arc Shape closed
Tubular structure, is provided with support spring between housing and filter core sub-unit, housing bottom is screwed with thread seal plate, thread seal plate
Body seal is provided with, check-valves is provided between thread seal plate and filter core sub-unit.
The filter core is annular in shape, and alkalinity additive layer, polypropylene layer, filter paper layer and doughnut are followed successively by from outside to inside
Layer, is equipped with gap between adjacent two layers.
The beneficial effects of the utility model：Formed at oil-out and intercepted, when oil filter is installed and used, mounting seat
Connection screw thread opens check-valves top, in order to the machine oil outflow after filtering, is easy to the installation of filter core sub-unit, dismantles oil filtration
After device, because connection screw thread loses the effect to check-valves, check-valves restores to the original state in the presence of elastic force, so as to dismantle more
When changing, internal lubricating oil leakage is prevented effectively from, keeps working environment clean.The flow direction of machine oil for sequentially pass through alkalinity additive layer,
Polypropylene layer, filter paper layer and doughnut layer filtering, then by doughnut layer center discharge cleaner.

Specific embodiment
Below in conjunction with Fig. 1 ~ 3, content of the present utility model is described in detail by specific embodiment.This prevents from dismantling oil leak
Oil filter includes housing 3, the filter core sub-unit 4 being arranged in housing.Wherein, housing is cylinder of the front end in circular arc Shape closed
Shape structure, is provided with support spring 5 between housing and filter core sub-unit, housing bottom is screwed with thread seal plate 2, thread seal plate
Body seal 1 is provided with, check-valves 6 is provided between thread seal plate and filter core sub-unit.Filter core is annular in shape, from outside to inside successively
It is alkalinity additive layer 7, polypropylene layer 8, filter paper layer 9 and doughnut layer 10, gap is equipped between adjacent two layers.
