Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil level gauge used for inspecting the amount and oxidation state of oil for automobile engines, and particularly to improve the confirmation of the upper and lower limits of the engine oil amount. It relates to the oil level gauge.

[0002]

2. Description of the Related Art Conventionally, such an oil level gauge is composed of a guide portion b provided with a grip portion, a guide port fitting portion and a measuring portion a, and is provided in a cylindrical guide pipe p communicating with an oil pan below a cylinder block. , The oil level gauge is inserted so that the guide port fitting part is tightly fitted to the guide port at the upper end of the guide pipe p, and only the measuring part a at the tip of the introducing body b is immersed in the engine oil o in the oil pan. At the time of inspection, the oil level gauge is pulled out from the guide pipe p, and the engine oil amount and the oxidation state in the oil pan are measured, inspected, and replenished with the engine oil o attached to the measuring portion a at the lower end of the introduction body b. Judgment is made on the replacement time, the replenishment amount, and the filling amount at the time of replacement.

As an example of the measuring portion a provided on the introduction body b in the conventional oil level gauge, as shown in FIG.
At the lower end of one surface of the elongated plate-shaped introducing member b, a mesh portion c is engraved in a cross hatching pattern, and a pair of lines d and d'parallel to the upper and lower portions of the mesh portion c and letters e and e'of F and L. The one engraved with was used.

When the oil level gauge is pulled out from the guide pipe p at the time of checking the amount of engine oil, since only one surface of the plate-like introduction body b is provided with the measuring portion a, only one surface can be confirmed. First, the measurement part a
It is necessary to check the surface of the introduction body b provided with, and there is a drawback that it is troublesome to confirm whether or not the engine oil amount is within an appropriate range.

Further, when the engine oil amount is inspected, it is often just after traveling, and the vibration of the vehicle causes the level of the engine oil o filled in the oil pan to sway and move up and down. The engine oil o rises from the oil pan to the upper part inside the guide pipe p, and the engine oil o is also adhered in the form of an oil film on the upper inner wall surface of the guide pipe p.

When the oil level gauge is pulled out upward from the guide pipe p, one surface of the introduction body b of the oil level gauge comes into surface contact with the inner wall surface of the guide pipe p, and the measuring portion a and a portion other than the measuring portion a. Also, the engine oil o is transferred and attached from the inner wall surface of the guide pipe p, is immersed in the engine oil o in the oil pan, and the engine oil o is attached to the oil level gauge in addition to the measurement portion a and the measurement portion a. However, there are drawbacks such that the original liquid surface position becomes unclear and the confirmation of the engine oil amount decreases.

Further, as a recent tendency, in order to reduce the weight of a vehicle, the engine room of an automobile has a space required for accommodating an engine and other mechanical devices reduced to a necessary minimum. Since it is equipped with various auxiliary equipment such as machine parts, the inside of the engine room has become complicated.

As a result, when the guide pipe p is attached to the cylinder block and the oil pan, the guide pipe p cannot be installed vertically, and the guide pipe p attached to the cylinder block has a large inclination with respect to the vertical direction. The engine, in which the guide pipe p becomes almost horizontal, also exists, and the inclination of the oil level gauge inserted into the guide pipe p having such a low inclination is inevitably low.

Therefore, as shown in FIG. 6, the position at which the oil level gauge inserted by inclination is immersed in the engine oil o is also in an inclined state, and the introduction body b has a plate thickness.
The position where the engine oil o adheres is different between the front surface side and the rear surface side of the introduction body b. For example, at the L level, the position where the lower surface is immersed at the time of insertion does not originally require replenishment of the engine oil o. On the upper surface at the time of inserting the measuring portion a, there may be a case of a last minute caution state that substantially coincides with the L line d ', and the judgment becomes different depending on the front and back of the oil level gauge being inserted, and the measuring portion a is not provided. It has the drawbacks that it is necessary to check and compare the states of both sides including the bottom side, and it is difficult to check the necessity of replenishment and the amount of replenishment.

Further, as a conventional oil level gauge,
Although not shown, a through hole may be provided in the plate thickness direction, or
As shown in FIG.
Some of the oil level gauges are also displayed, but such an oil level gauge is in a state of partial loss of material, so the strength at the holes or notches f and f ′ is reduced. However, there is a drawback that becomes a big problem when the guide pipe p is complicatedly bent.

DISCLOSURE OF THE INVENTION The present invention provides an oil level gauge which makes it easy to check how the engine oil amount is in relation to the FL level and also improves the strength. To do.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the problem that it takes time to check the upper and lower limits of replenishment, replacement timing, replenishment amount, and filling amount based on the above-mentioned prior art. The upper and lower limits are confirmed by comparing the irregularities on the front and back with the engine oil that has adhered by providing the irregularities corresponding to the front and back, that is, the mesh portion engraved in the conventional cross hatching pattern. Compared with the above, it is possible to confirm on both sides of the introduction plate body, and further an oil pool is generated in the concave portion to improve the confirmability.

Further, based on the above-mentioned conventional technique, it is difficult to confirm the upper and lower limits depending on the pulled-out state of the oil level gauge, a confirmation error occurs depending on the mounting state of the guide pipe, and some oil level gauges have poor strength. In view of the problem of decreasing, the convex portion prevents the oil from adhering to the entire guide plate body by the convex portion contacting the inner wall surface of the guide pipe to improve the confirmation, and the convex portion serves as a reinforcing rib. Even if there is a difference in both sides due to the fact that the strength is improved or both sides are confirmation surfaces, the above problems can be solved by making it possible to confirm the respective states and facilitate the comparison on both sides.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is an oil level gauge according to the present invention,
As shown in FIG. 1, the oil level gauge 1 includes a grip portion 2 from above, a guide port fitting portion 3 made of synthetic resin, an introduction plate body 4 made of a metal plate having flexibility and resilience, and The measuring portion 5 provided at the tip of the introducing plate body 4 is connected to be integrated.

Although the introduction plate body 4 is shown as a metal plate, it may be a metal wire body such as a wire, or the introduction plate body 4 and the measuring section 5 may be separate bodies, that is, It suffices that the lower end portion of the introduction plate body 4 on which the measurement unit 5 is provided has a plate shape.

As shown in FIGS. 2 and 3, the measuring unit 5 has a pair of upper and lower concave and convex portions provided below the introduction plate body 4 at a longitudinal center line position with a predetermined interval for displaying an appropriate amount of engine oil. 6 and 6a, which correspond to the front and back sides of the introducing plate body 4, the front surface 7 side is formed with concave portions 8 and 8a, and the back surface 9 side is formed with convex portions 10 and 10a at the same position.

Incidentally, the concave and convex portions 6 and 6a provided on the front surface 7 side and the rear surface 9 side of the introduction plate body 4 are shown as a pair of upper and lower parts, respectively, which are projected in the same direction. The protruding directions of 6a and 6a may be opposite to each other, and the uneven portions 6 and 6a are provided one above and one below in the transverse direction, for example, when the width of the introducing plate 4 is wide. You may provide several uneven | corrugated parts 6 and 6a in the cross direction.

Further, as means for forming the concave and convex portions 6 and 6a provided on the introducing plate body 4, an upper mold and a lower mold having concave and convex portions opposite to each other are used to emboss the mold to the introducing plate body 4 to form a convex portion. The 10 and 10a are embossed.

Concavo-convex portions 6 and 6a formed by such embossing
Are concave portions 8 and 8a and convex portions 10 at positions corresponding to the front and back sides of the introducing plate body 4,
Since the material introducing plate 4 and the concavo-convex portions 6 and 6a are continuous with each other to form 10a, there is no loss of the material, and the concavo-convex portions 6 and 6a also serve as reinforcing ribs.

Next, the operation of the oil level gauge according to the present invention will be described. The uneven portion 6 of the measuring portion 5 provided at the lower end of the oil level gauge 1 pulled out upward from the guide pipe 11 communicating with the oil pan of the cylinder block. ,
In the vicinity of 6a, the engine oil adheres to the introduction plate body 4 and enters the concave portions 8 and 8a of the concave and convex portions 6 and 6a of the introduction plate body 4 and the concave portions 8 and 8a serve as oil sumps. Check the upper and lower limits.

The amount of engine oil can be confirmed by checking the engine oil attached to the front and back surfaces 7 and 9 of the introducing plate 4 and the measuring portion 5.
The positions of the concave portions 8 and 8a or the convex portions 10 and 10a, and whether the engine oil is accumulated in the upper and lower concave portions 8 and 8a.
Judge and confirm with.

It should be noted that the uneven portions 6 and 6a indicating the upper and lower limits of the oil level gauge 1 are for confirming whether the engine oil is insufficient or overfilled, and the engine oil amount is within an appropriate range. If there is any filling amount, the level of the engine oil adhering to the oil level gauge 1 may be between the upper and lower concave and convex portions 6 and 6a. Can be judged to be bonari like the conventional one.

When the oil level gauge 1 is pulled out from the guide pipe 11, the projections 10 and 10a provided on the back surface 9 of the introduction plate 4 come into contact with the inner wall surface 12 of the guide pipe 11 as shown in FIG. When the oil level gauge 1 is pulled out from the guide pipe 11, even if the front surface 7 and the back surface 9 of the introduction plate 4 do not contact the inner wall surface 12 and engine oil adheres to the convex portions 10 and 10a, In addition, stains on the entire front surface 7 and the back surface 9 are prevented and suppressed.

When a plurality of concave-convex portions 6 and 6a are provided in the transverse direction of the introduction plate body 4, although not shown, the drawn-out state of the introduction plate body 4 is stable and the width direction end of the introduction plate body 4 is stable. The oil adhesion of the introduction plate body 4 including the parts is further suppressed.

When the guide pipe 11 is inclined at a low angle, both front and back surfaces 7 of the oil level gauge 1,
The amount of engine oil filled can be checked by measuring the engine oil that has adhered to 9 or accumulated in the recesses 8 and 8a and making a comprehensive determination of the results measured on both front and back surfaces 7 and 9. You can

[0026]

In summary, according to the present invention, since the measuring portion 5 provided at the lower end portion of the introduction plate body 4 of the oil level gauge 1 is provided with the pair of upper and lower concave and convex portions 6 and 6a at positions corresponding to the front and back sides, the introduction plate body is provided. 4, the concave portion 8, 8a on the surface 7 side of the measuring portion 5
However, since there are convex portions 10 and 10a on the back surface 9 side,
The amount of engine oil can be confirmed by comparing the level of engine oil adhering to the surface of the introduction plate 4 and the positions of the concave portions 8 and 8a or the convex portions 10 and 10a, and the mesh portion engraved in the conventional cross hatching pattern can be confirmed. Compared to the above, it can be confirmed on both the front and back surfaces 7 and 9 of the oil level gauge 1,
It is easy to measure the engine oil amount,
Further, since the engine oil is accumulated in the recesses 8 and 8a to form an oil reservoir, the amount of engine oil can be confirmed only by the presence or absence of the oil reservoir, and the measurement work can be further facilitated.

When the oil level gauge 1 is pulled out, the protrusions 10 and 10a on the back surface 9 are the inner wall surfaces of the guide pipe 11.
If the oil level gauge 1 is inserted into the guide pipe 11 so as to come into contact with the guide pipe 11, the entire front surface 7 and back surface 9 of the introduction plate body 4 do not come into contact with the inner wall surface 12 when the oil level gauge 1 is pulled out. By pulling out the oil level gauge 1 from the guide pipe 11, the engine oil transferred from the inner wall surface 12 does not adhere to the recesses 8 and 8a of the front surface 7 and the back surface 9, and only the engine oil to be measured is the oil level gauge. In the state where the oil adheres to No. 1, the engine oil, which is a erroneous recognition element, does not adhere, and the confirmation can be improved.

Further, since the concave-convex portions 6 and 6a are in an embossed state with no material defects, the concave-convex portions 6 and 6a are in the state of reinforcing ribs and the strength of the introducing plate 4 can be improved.
Further, since the introduction plate body 4 is processed only by forming the concavo-convex portions 6 and 6a, it is possible to reduce the cost of the oil level gauge 1 without the conventional cross-hatched mesh portion c.

Further, even if the guide pipe 11 is inclined at a low angle as compared with the conventional one having the mesh portion engraved in the cross hatching pattern, which is confirmed by only one surface, The engine oil that adheres to the front and back surfaces 7 and 9 or that accumulates in the recesses 8 and 8a can be used to make comprehensive judgments on different measured values. Or oil level gauge 1
The state of attachment of the front and back sides is not particularly restricted, and the attachment to the guide pipe 11 can be facilitated.

Further, since the protrusions and recesses of the concavo-convex portions 6 and 6a are formed in the same direction, they are in the same direction at the time of embossing for forming the concavo-convex portions 6 and 6a on the introduction plate body 4, improving workability, and further improving the guide pipe. In the state of being inserted into 11 and when being pulled out, the oil transfer and adhesion from the inner wall surface 12 to the introduction plate body 4 can be suppressed over the entire length, which is a great practical effect.
