Description

A kind of oil filter of being convenient to assemble

Technical field

The utility model relates to a kind of auto parts and components, especially relate to a kind of sealing good, assemble simply and easily oil filter.

Background technique

The Main Function of engine motor oil is farthest to reduce each parts to produce impurity, reduce energy loss and parts depreciation because of friction in running.Motor can produce a large amount of wearers such as iron filings after working long hours, these wearers can enter in the machine oil, therefore must recycle machine oil to this part and carry out the filtering processing, so that the machine oil that recycles behind the removal of contamination is reused.The employed machine oil of motor car engine generally filters by filter cleaner at present, its effect is the impurity such as dust, carbon precipitates and coal soot of removing in the machine oil, especially the metal granule such as iron filings, assurance is with kinematic pair such as the engine oil supplying bent axle of cleaning, connecting rod, camshaft, pressurized machine, piston rings, make machine oil play lubricated, cooling, cleaning action, thereby prolong the life-span of these component.So the performance of oil filter directly affects the performance and used life of motor, the normal operation of motor is played key effect.

Oil filter is generally fallen the contaminant filters such as the dust in the machine oil, iron filings by the filter paper in its inner filter core; but after filter paper uses a period of time; filter paper can be stopped up by impurity; smooth and easy for guaranteeing fuel feeding; oil filter has all been installed bypass valve arrangement mostly, and after filter paper was blocked, bypass valve can be opened under the oil pressure effect; allow the machine oil of filtered directly flow to motor, so bypass valve is the key of in case of emergency protecting motor.

Be connected between the bypass valve of present most of filter cleaner and the lid all is the mode that adopts spot welding or riveting, the spot welding machine that this Placement need are special-purpose and riveting die and skilled operator, the bad product that produces can't be done over again, the defective products rate is high, such as notification number be: a kind of oil filter that is used on the light-duty vehicle that the Chinese model utility of CN2065942U provides, it comprises the band oil inlet hole, the filter cover of oil outlet is with the filter bowl housing that is connected this filter cover and be contained in the interior filter core assembly of housing, filter cover directly adopts with the filter bowl housing and is threaded, filter cover is provided with the circular groove of dress seal ring, and seal ring compresses by convex edge on the filter bowl housing.This patent adopts the Placement of spot welding, after the filter cleaner internals damages, and the very inconvenience of member of installing and more renewing, and sealing is relatively poor.

The model utility content

The utility model mainly is for the existing existing installation of oil filter and changes member inconvenience, the poor problem of sealing, and a kind of simple and convenient, firm and reliable connection, good oil filter of being convenient to assemble of sealing of assembling is provided.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of oil filter of being convenient to assemble, the shell that comprises an end opening, be provided with tubular element and bypass valve in the shell, the opening of described shell is provided with the thread plate that is connected with the oil filter base of motor, be provided with supported spring between filter core and the shell, one end of filter core and thread plate butt, the other end and supported spring butt, form oil passageway between the sidewall of filter core and shell, thread plate is provided with the filler opening that is communicated with described oil passageway, the intermediate flow channel of filter core is communicated with oil passageway, bypass valve is arranged on the intermediate flow channel place of filter core, and bypass valve is provided with Returnning spring.The oil filter base of this oil filter and motor is used; oil filter base is connected with thread plate; machine oil enters filter cleaner inside by oil pipe from filler opening; the oil passageway of flowing through, and the filtration by filter core fall the contaminant filters such as the dust in the machine oil, iron filings; machine oil after the filtration filter core intermediate flow channel of flowing through; and finally enter in the oil filter base, and then the kinematic pair such as lubricated bent axle, connecting rod, camshaft, pressurized machine, piston ring, the protection engine component.Also be provided with the bypass valve with protective action in this oil filter, after filter core stops up, oil pressure will promote Returnning spring, so that bypass valve is opened, excessive machine oil flows directly in the oil filter base, thereby guarantee that motor can access the sufficient lubrication of machine oil all the time.Filter core is connected in the shell by supported spring, and under the active force of supported spring, filter core can be pressed on the thread plate all the time, and this cleaner structure is reliable and stable, and each parts dismounting and upgrade simple and convenient.
