Description

[Detailed Description of the Invention] This invention relates to a case structure for an oil level gauge used at a gas station.

Traditionally, the oil level in gasoline tanks buried underground at gas stations has been determined using oil level gauges.
Since the oil level gauge is built into a certain case and installed outdoors, rainwater may collect on the stepped glass window attached to the top of the case and enter the inside of the case. This may cause damage to the oil level gauge, so in order to eliminate this drawback,
If the glass window were to be flush with the top surface of the case body and completely flat, the mounting structure for the glass plate of the glass window would be complicated, and there was a risk that gaps would occur for rainwater to infiltrate.

In this idea, a step part with a wide bottom part is integrally provided on the periphery of the glass window provided on the upper panel of the case body that houses the oil level gauge, and a step part with a wide bottom part is provided on the periphery of the glass plate. At the same time, the glass plate is attached to the glass window by interposing a rubber gasket between the step part of the glass plate and the step part of the glass window of the case body, and the top and bottom surfaces of the glass plate are attached to the glass window. and the upper and lower surfaces of the upper plate of the case body are configured to be on the same plane, and a fixing flange for fixing the glass plate is provided on the lower surface of the case body to simplify the mounting structure of the glass plate. It is an object of the present invention to provide a case structure for an oil level gauge that can completely prevent accumulation and infiltration of rainwater.

The embodiment of this invention will be explained in detail based on the drawings. A indicates an oil level gauge, and the oil level gauge A uses a scale tape to measure the oil level in a gasoline tank buried underground in a gas station. The oil level gauge A has a scale tape on the top surface to measure and indicate the oil level position.

The oil level gauge A is housed in a case body B, and the case body B is formed in a rectangular shape. It can be installed freely with 3 bolts.

On the upper side of the case body B, a rectangular glass window 4 is provided in the center.
A glass plate 5 is attached so that the scale display of the oil level gauge A can be read through the glass window 4.

The glass plate 5 has a lower protruding stepped portion a integrally formed at its peripheral edge, and the lower surface c of the glass plate 5 protrudes outward from the upper surface b, forming a wide shape.

Such a glass plate 5 may be manufactured by processing a single glass plate to form a step a on its peripheral edge, or may be manufactured by laminating two glass plates together to form the step a.

The glass window 4 of the case body B to which the glass plate 5 configured as described above is attached is configured by opening a rectangular window in the center of the upper side plate 6 of the case body B.
At the periphery of the glass window 4, there is integrally formed a stepped part a' which is expanded at the lower part and is opposed to the stepped part a of the glass plate 5. By fitting into the glass plate 5, the stepped portion a' of the glass plate 5 is brought into contact with the stepped portion a' of the glass window 4.

Here, the thickness l of the glass plate 5 is formed to be the same as the thickness l' of the upper plate 6 of the case body B, and when the glass plate 5 is fitted into the glass window 4, the upper surface of the glass plate 5 b is formed at the same height as the upper surface b' of the upper side plate 6 of the case body B, and the lower surface c is the same flat surface as the lower surface c' of the upper side plate 6, respectively.

7 is the stepped portion a of the glass plate 5 and the stepped portion of the case body B.
This is a rubber gasket interposed between a' and a'.

Reference numeral 8 denotes a fixing flange for fixing the glass plate 5, which is pressed from the lower surface of the upper plate 6 of the case body B to the periphery of the lower surface c of the glass plate 5, and bolts 9 are attached to the upper plate 6 in order to fix the glass plate 5. It is fixed by

The embodiment of this invention is constructed as described above, and the upper surface b of the glass plate 5 fitted and attached to the glass window 4 is flush with the upper surface of the upper plate 6 of the case body B, and is flat. As a result, rainwater, etc. flows from the glass plate 5 to the outside of the case body B without accumulating on the glass plate 5 surface, and the lower surface c of the glass plate 5 is the same surface as the lower surface of the upper side plate 6 of the case body. Therefore, by pressing and fixing the fixing flange 8 from below, the glass plate 5 can be securely fixed, and leakage of rainwater and the like into the case body can be completely prevented.

According to this invention, a stepped portion with a lower expanded shape is integrally provided on the periphery of the glass window provided on the upper panel of the case body that houses the oil level gauge, and the periphery of the glass plate is
Since the stepped portion with a wide lower part is integrally formed, the structure is simple and processing and assembly are easy.

Further, since a rubber gasket is interposed between the stepped portion on the glass window side and the stepped portion of the glass plate, waterproofing is ensured and rainwater is prevented from entering.

Further, since the glass plate is fitted to the glass window and the upper surface of the glass plate is flush with the upper surface of the upper plate of the case body, it is possible to eliminate the phenomenon of rainwater and the like accumulating on the glass plate surface.

In addition, since the lower surface of the glass plate is the same surface as the lower surface of the upper plate of the case body, the fixing flange is pressed against this same surface to fix the glass plate to the upper side of the case body. As a result, the method for attaching and fixing the glass plate becomes a simple structure, and the glass plate can be attached reliably.
