Description

[Detailed Description of the Invention] This invention relates to a drain plug attachment/detachment tool for an automobile engine oil pan used during engine oil replacement work.

Conventionally, when removing the drain plug of an oil pan of an automobile engine or the like to replace engine oil, the oil temperature is raised to lower the viscosity of the engine oil and the engine oil is discharged.

However, since the drain plug must first be loosened using a socket wrench or a box wrench, and then turned by hand to remove it, the heat of the engine oil is conducted to the drain plug, which may cause burns or damage to the hands. There was a problem when I released the drain plug and dropped it.

Furthermore, after removing the drain plug, hot engine oil splashes onto hands and clothes, causing burns and staining hands and clothes.

This invention solves the above problems and provides a drain plug removal tool for an automobile engine oil pan that allows you to drain engine oil without touching the drain plug or staining your hands or clothes. purpose.

The drain plug removal tool for an automobile engine oil pan of this invention includes a funnel-shaped main body with a bellows-shaped elastic member on the upper outer periphery and an oil drain hole bored in the lower part, and a concentric part inside the funnel-shaped main body. The main feature is that the drain plug includes an inner cylinder whose inner peripheral shape corresponds to the outer peripheral shape of the drain plug.

Hereinafter, the drain plug attachment/detachment tool for an automobile engine oil pan of this invention will be explained based on the illustrated example.

Figure 1 is a front view showing an embodiment of this invention, Figure 2 is a plan view of the same, Figure 3 is a sectional view taken along line A-A in Figure 2, and Figure 4 is an embodiment of this invention. The perspective view and FIG. 5 are partially cutaway views of an embodiment of this invention.

In order to improve the flow of engine oil and prevent the engine oil from scattering, the upper outer periphery of the funnel-shaped main body 2 is provided with a groove that fits tightly to the oil pan 6 during work to prevent the engine oil 10 from scattering. A bellows-shaped elastic member 1 made of, for example, rubber is provided so as to do so.

The lower part 9 of the funnel-shaped main body 2 is formed into a hexagonal column shape so that a box wrench or the like can be used, and an oil drain hole 3 for discharging engine oil is bored near the center of the lower funnel-shaped main body 9. ing.

Furthermore, inside the funnel-shaped main body 2, an inner cylinder 4 is formed concentrically with the funnel-shaped main body 2 and has an inner circumferential shape corresponding to the outer circumferential shape of the drain plug 7 (hexagonal in the illustrated example). For example, it is provided via a rib 5.

To drain engine oil using the automotive engine oil pan drain plug removal tool of this invention, first remove the drain plug 7 screwed onto the oil pan 6.
first loosen it with a box wrench, etc., then insert the inner peripheral surface of the inner cylinder 4 provided inside the funnel-shaped main body 2 into the drain plug 7.
Insert a box wrench into the lower part 9 of the funnel-shaped main body and turn the box wrench, or turn the funnel-shaped main body 2 by hand to remove the drain plug 7.

At this time, the drain plug 7 is held at the upper part of the inner cylinder 4, and the engine oil 10 is discharged from the oil drain hole 3 through the elastic member 1 and the inner wall of the funnel-shaped main body 2, and a receiver receiving the engine oil 10 is formed below. 8 etc.

After draining the engine oil 10, screw the drain plug 7 into the oil pan 6 in the reverse order of removal.

In addition, if the inner cylinder 4 is installed in the funnel-shaped main body 2 by increasing the strength of the rib 5, for example, the inner cylinder 4 will be attached to the drain plug 7 from the beginning.
It can be removed by inserting the inner peripheral surface of the

Since this invention has the above-mentioned configuration, the drain plug is held in the inner cylinder during the draining operation, and the bellows-shaped elastic member and funnel-shaped body prevent the engine oil from scattering.
This results in the effect that engine oil can be drained without touching the drain plug and without staining hands or clothes.
