Description

Protective device of fuel oil coarse filter

Technical Field

The utility model relates to a safety device of vehicle fuel strainer especially relates to a protector of fuel strainer.

Background

It is known that, the car often can roll road surface stone in service, leads to the stone to splash and hits the plastics cup of fuel strainer, if cup damage diesel oil leaks, gets into the air among the oil feeding system, will cause the engine to park, directly influences the safety of traveling of vehicle, and the plastics cup of current car fuel strainer all does not have effectual safeguard measure, and the unexpected damage of cup will directly influence the safety of traveling of car.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a simple structure, can effectively protect the car in service when rolling road surface stone, the plastics cup is hit by the stone that splashes to the fuel strainer, prevents that the damaged diesel oil of cup from leaking to the protector of the safe fuel strainer that traveles of protection vehicle. The protection device of the fuel oil coarse filter comprises a crude fuel oil coarse filter, a compression bolt 1 and a plastic cup 2, wherein a hollow protection cover 3 with a cylindrical middle part and a hemispherical bottom is arranged outside the plastic cup, the end part of the protection cover is fixed through the compression bolt on a pressure plate of the fuel oil coarse filter, and the radian of the protection cover body is matched with the cup.

The protective cover on open and to have a bar hole 5, the protective cover adopts the metal to make and has certain intensity.

The protective cover is a metal net structure with certain hardness.

From the technical scheme of the utility model, the fuel strainer also called oil water separator, owing to be equipped with the protection casing in the outside of former fuel strainer, the protection casing comprises shapes such as cylinder and spheroid, possesses certain shock resistance, has avoided splashing a series of safety problems such as damage, oil feeding system short circuit, engine parking, the power steering oil pump is out of work, the direction does not have the helping hand that stone directly strikes the plastics cup and leads to. Because the protective cover is provided with the strip-shaped holes or is arranged to be of a net-shaped structure, the fuel oil coarse filter on the market is usually a transparent cover, such as a 1100-plus 54051 type fuel oil coarse filter, the separation state in the fuel oil coarse filter can be observed, the water is conveniently drained in time, and the scheme has the advantages of simple structure, convenience in installation and effective protection. Therefore, the utility model discloses simple structure has realized completely, can effectively protect the car in service when rolling road surface stone, and the plastics cup is hit by the stone that splashes to the fuel strainer, prevents that the damaged diesel oil of cup from leaking to the safe invention purpose of going of protection vehicle.
