Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil drain for oil change used in a vehicle engine or the like.

Generally, in a vehicle engine, etc., it is necessary to replace lubricating oil regularly or irregularly.

For this purpose, a drain port is opened in the oil pan of a vehicle engine, etc., and this drain port is closed with a plug made in the shape of a stopper.

However, with such a drain plug,
When the plug was removed, the lubricating oil in the oil pan was often accidentally scattered, staining the workers' clothes and the work floor.

These drain plugs tend to loosen when removed during power changes, or when tightened carelessly, the seal becomes incomplete, often resulting in dangerous lubricant leaks.

For this reason, attempts have been made in the past to solve the above-mentioned inconvenience by assembling a shut-off valve at the drain port. In practice, such attempts are unsuccessful because of the possibility of storage.

Furthermore, although an engine oil removal device as shown in Japanese Utility Model Application Publication No. 47-15808 has been proposed, although this device has the advantage of being able to be operated remotely, it has a large structure. A mounting hole must be made in the oil pan, which may open accidentally due to impact, and there is a high possibility of oil leakage due to damage to the valve seat.Since the valve passage is narrow, it takes a long time to drain the oil. The problem is that it takes a long time.

The present invention was developed in consideration of the conventional situation as described above.
It can be used simply by attaching it to the drain port of the oil pan, and it will not open accidentally due to vibration etc., there is no possibility of oil leakage, the time required to drain the oil is short, and it is easy to open and close when changing the oil. This paper proposes a method for draining oil from vehicle engines, etc., that can be done.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

FIG. 1 is a partially cutaway front view of an oil drain according to the present invention, and there is a valve inside a base material 2 formed with a tapered screw 1 that can be screwed into an oil pan (not shown). A chamber 3 is formed in which a spherical valve 4 is accommodated.

A socket 5 is screwed into the opposite end of the tapered screw 1 of the base material 2, and the spherical valve 4 is seated on seats 6a and 6b provided inside the base material 2 and at the inner end of the socket 5. By doing so, the passage 7 is closed.

The base material 2 has a shaft hole 8 orthogonal to the passage 1.
A stem 10 sealed with an O-ring 9 is rotatably positioned in the shaft hole 8.

The stem 10 has a head 10a shaped like a square shaft, and this head 10a is inserted into the square hole of the spherical valve 4.

Further, a spring housing chamber 11 is provided inside the extension portion 2a of the base material 2.
is formed, and a compression spring 12 is positioned in this spring housing chamber 11.

A plug 13 having a square head is loosely screwed into the opening of the extension part 2a with a fitter stopper plate 14 interposed on the square shaft part 10b of the stem 10. Square hole 1 of bar handle 15
6 is fitted.

Therefore, although the rod handle 15 is pressed in one direction by the compression spring 12 and can slide on the square shaft portion 10b, the rotational position of the rod handle 150 is regulated as follows.

That is, as shown in FIG.
The rod handle 15 is led out from.

The groove 17 consists of a vertical groove 17a and a horizontal groove 17b communicating with one end of the vertical groove 17a, and when the rod handle 15 is positioned in the vertical groove 17a, the spherical valve 4 is in the closed position shown in FIG. be placed.

When the rod handle 15 is located at the end of the horizontal groove 17b displaced by 900 degrees from the vertical groove 17a in the rotational direction of the stem 10, the valve body 4 is buttoned to the open position shown in the third figure.

As is clear from the above description, the oil drain of the present invention is used by screwing the tapered screw 1 into the drain port of an oil pan of a vehicle engine or the like.

In that case, by aligning the rod handle 15 with the longitudinal groove 17a, the rod handle 15 is pressed by the force of the compression spring 12 to a position where it hits the stopper plate 14 as shown in the first figure.

Therefore, since the rod handle 15 is locked to the end of the longitudinal groove 17a, the stem 10 is not inadvertently moved to the open position by mechanical vibrations.

Also, when changing the oil, by pushing down the rod handle 15 against the force of the compression spring 12 and rotating the rod handle 15 approximately 96 degrees, the ball valve 4 can be placed in the open position as shown in the third figure. can.

In the end, the oil drain of this invention can be used simply by attaching it to the drain port of the oil pan, and in the closed position it is double sealed by the pair of seams 6a and 6b, so there is no danger of dangerous oil leaks. .

In addition, in this closed position, it is firmly locked in the closed state by the force of the compression spring 12 protected in the extension portion 2a of the base material 2, so that it will not be accidentally opened due to vibration or the like.

The structure of the stem 10, the compression spring 12, and the extension part 2a of the base material 2 according to the present invention not only provides a structure that can be used simply by attaching it to the drain port, but also protects it from stones, dirt, etc. that are thrown up while the vehicle is running. , to protect important parts and prevent unexpected damage.

Furthermore, in the oil draining method of the present invention, since the cross-sectional area of the oil passage can be made relatively large, it is possible to drain the lubricating oil within one minute or so.
