Description

Drainage of fuel and oil tanks

The present invention relates to a drainage device for fuel and oil tanks, and more particularly, to an improvement in the fastening structure of a drain plug manually opened by an operator to remove water and impurities contained in the fuel and oil tank.

As is well known, a fuel tank constituting a fuel device of an automobile is composed of a tank body in which fuel is stored, an inlet pipe, a sender unit of a fuel gauge, and the like, and therein prevents fluctuation of fuel while driving and at the same time the strength of the tank. Separator is installed to increase the. In addition, the inner surface of the tank is made of a rust preventive structure to prevent rust by moisture.

On the other hand, the oil tank (or fan) constituting the lubrication device of the vehicle is mounted by a fastening means such as a bolt in the lower portion of the cylinder block in which the crankshaft is installed, and has a structure in which lubricating oil is accommodated.

The lower part of the fuel and oil tank collects the water condensed in the tank during long-term use and foreign matter injected together when the fuel and oil are injected.

To eliminate this, conventional fuel and oil tanks are equipped with a drain level. The drainage device can be used to completely remove residual fuel and oil inside the fuel and oil tank during A / S.

1 shows a conventionally known drainage device. Reference numeral 1 in the drawings refers to the lower case of the fuel and oil tank.

The lower case 1 of the fuel and oil tank is provided with a drain plug 2 penetrating the body of the case. The drain plug 2 is fixed by being screwed with the seat member 3 provided inside the lower case 1.

This drain plug 2 is released by an operator to remove water and foreign matter inside the fuel and oil tank, thereby removing water, foreign matter or residual fuel therein.

In the drain apparatus of the fuel and oil tank described in the prior art, the drain plug has a problem in that water, foreign matter and residual fuel are discharged at the initial stage of opening by the operator, thereby contaminating the operator's hand.

In addition, the above-described fuel and oil will make the manual operation of the operator uncomfortable.

The present invention has been proposed for the purpose of solving the above-mentioned problems of the prior art, by blocking the fuel and oil leaking to the outside at the initial opening of the drain plug, to prevent contamination of the operator's hand, improve workability Provide drainage of fuel and oil tanks as far as possible.

Hereinafter, on the basis of the accompanying drawings will be described in detail the configuration and operation of the present invention.

2 is a cross-sectional view showing a drain device for a fuel and oil tank according to the present embodiment.

In describing the present embodiment, the same reference numerals are used for the clarity of description for the configuration of the present embodiment that is the same as the drawings cited in the prior art.

Reference numeral 1 in the drawings refers to the lower case of the fuel and oil tank.

The lower case 1 is installed in the upper case in the case of the fuel tank, it is installed in the cylinder block in the case of the oil tank.

The lower case 1 of the fuel and oil tank is provided with a discharge port 6 through which water, foreign substances, fuel or oil are drained, and a sheet member 3 is provided inside the discharge port 6.

A thread is formed on the inner circumferential surface of the sheet member 3 to be engaged with the drain plug 4.

The drain apparatus of the present embodiment including such configurations proposes a means for shutting off fuel and oil leaking through a gap therebetween at the initial opening of the drain plug 4.

More specifically, the packing member 5 of the rubber material is installed in the hollow of the drain plug 4. The end of the packing member 5 protrudes forward than the end of the drain plug 4, and a thread is formed on the outer circumferential surface thereof.

The packing member 5 is coupled to the seat member 3 while being rotated together with the drain plug 4 when the drain plug 4 is coupled. To this end, the inner circumferential surface of the threaded sheet member 3 is formed in two steps.

Based on the configuration of this embodiment described above, the packing member 5, even when the drain plug 4 is opened, even after the fastening state of the drain plug 4 and the sheet member 3 is released first, The state of engagement with the sheet member 3 is maintained.

At this time, the operator forcibly and quickly removes the coupling state of the rubber member packing member 5 and the sheet member 3, thereby preventing the worker's hands from being contaminated.

Through the embodiments described above, it can be seen that the drain device of the fuel and oil tank according to the present invention substantially solves the problems of the prior art.

That is, according to the present invention, when the drain plug is opened to remove water and impurities contained in the fuel and oil tanks, it is possible to obtain an effect of preventing fuel and oil from spilling and contaminating the operator's hand.

In addition, since the operator's hand is not contaminated, maintenance workability can be improved.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Modifications may be made.
