Description

[Detailed description of the invention] [Field of industrial application] This invention relates to oil level gauges, and in particular,
The present invention relates to an oil level gauge in which a handle extends from one end of a packing part, a guide part extends from the other end, and a gauge part is provided at the tip of the guide part.

[Conventional technology]

Conventional oil level gauges of this type have a fourth
As shown in the figure, a steel bar 15 on which a handle portion 12 is formed
is passed through to the other end side of the packing part 11, a hole 17 is drilled at the tip thereof, the base end of the guide part 13 is inserted into this hole 17, and the guide part 13 is crimped.
There is one that has 3 fixed.

Further, as shown in FIG. 5, the steel bar 25 on which the guide part 23 is formed is passed through to one end side of the packing part 21, and the handle part 22 is formed integrally with the packing part 21 at the tip thereof, and a side groove is formed in the packing part 21. There is a processed version of 27.

Furthermore, as shown in FIG.
There is one in which the guide part 33 is formed by penetrating the packing part 31 and a hole 37 is formed at the upper end of the guide part 33 close to the packing part 31.

[Problem that the invention aims to solve]

However, among such conventional devices, the one shown in FIG. 4 does not have a breather function at all.

In addition, the device shown in FIG. 5 can perform a breather function by means of a side groove 27 formed in the packing part 21, but as shown in FIG. 6, dust, water, etc. It is unavoidable that foreign matter enters into the guide pipe 29 from the outside.

Furthermore, the one shown in FIG. 7 performs a breather function by allowing the air that has entered the hollow steel pipe 35 through the hole 37 to be released into the atmosphere from the tip of the handle 32 as shown by the arrow. However, it is difficult to process the hole 37, and the cost is high.
Since the hole 37 cannot be formed unless the diameter of the hollow-hole pipe 35 is quite large, it cannot be used when the inner diameter of the mating guide pipe is small.

As mentioned above, all of the conventional oil level gauges have had various problems.

The purpose of this invention is to solve the above-mentioned problems of the conventional oil level gauge, and to provide an oil level gauge that can function as a breather without drilling holes, and can also prevent foreign matter from entering from the outside. That is.

[Means to solve the problem]

This invention is to achieve the above-mentioned objectives,
In an oil level gauge having a handle portion extending from one end of a packing portion and a guide portion extending from the other end with a gauge portion at its tip, the handle portion is formed from a hollow tube which penetrates and protrudes through to the other end of the packing portion, the base end of the guide portion is inserted into the hollow tube from this protruding portion, and the protruding portion is crimped to secure the hollow tube and the guide portion together while ensuring an air flow passage passing through both ends of the hollow tube.

[Effect]

This invention employs the above-mentioned means, so that the breather function is performed by the airflow passage passing between both ends of the hollow tube.

〔Example〕

Embodiments of this invention shown in the drawings will be described below.

1 to 3 show an embodiment of an oil level gauge according to this invention, which has a handle part 2 extending from one end of a packing part 1, and a guide part 3 extending from the other end. extends, and a gauge portion 4 is provided at the tip thereof.

The handle portion 2 is formed of a hollow steel pipe 5, which penetrates to the other end of the packing portion 1 and projects.

The proximal end of the guide portion 3 is inserted into the hollow steel pipe 5 through the protrusion 6, and the protrusion 6 is caulked.

Therefore, the hollow steel pipe 5 and the guide part 3 are fixed together by caulking the protruding part 6, and on the other hand, since the packing part 1 is vulcanized and bonded to the hollow steel pipe 5, the packing part 1, the handle part 2 and the guide section 3,
It is formed integrally with the gauge section 4.

Moreover, as shown in FIG. 2, in the protruding part 6, a space 7 is formed between the hollow steel pipe 5 and the base end of the guide part 3 on both sides in the caulking direction, and a third
As shown in the figure, a space 7 is formed between the hollow steel pipe 5 and the base end of the guide part 3 above the protrusion 6, and therefore, a space 7 is formed between the hollow steel pipe 5 and the base end of the guide part 3. An air flow passage 8 is formed therein.

Next, the operation of the above will be explained.

In the oil level gauge according to this invention, first, the air flow passage 8 penetrating between both ends of the hollow steel pipe 5 can perform a breather function.

Moreover, there is no need to drill holes in the hollow steel pipe 5 in order to perform the breather function.

Moreover, since there is no need to provide a side groove in the packing part 1, foreign matter such as dust and water is reliably prevented from entering the inside of the guide pipe 9 from the outside.

[Effect of idea]

As described above, this invention is an oil level gauge in which a handle extends from one end of a gasket part, a guide part extends from the other end, and a gauge part is provided at the tip of the oil level gauge, in which the handle part is formed of a hollow tube. Then, the hollow tube is penetrated and protruded to the other end of the packing part, the proximal end of the guide part is inserted into the hollow tube from this protrusion, and the protrusion is caulked to connect the hollow tube. The guide portion is fixed to the guide portion while ensuring an air flow passage passing between both ends of the hollow tube between the two, so that the breather is secured by the air flow passage passing between both ends of the hollow tube. In addition, since hole processing is not required, the cost associated with hole processing can be reduced, and the thickness of the hollow tube can be made relatively thin.
Furthermore, since no side grooves are formed in the packing portion, it has excellent effects such as being able to reliably prevent foreign matter from entering from the outside.
