Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an oil filling hole for putting oil into an underground tank of a gas station or the like.

[0002]

[Prior art]

 For example, gas stations have underground tanks for storing oil. There are several types of petroleum at petrol stations, including kerosene, regular gasoline, and high-octane gasoline. As for underground tanks, multiple tanks of this type will be installed in parallel. Refueling of these underground tanks is generally divided into a plurality of tanks so that a plurality of types of oil can be loaded on a tank truck. When refueling, select the type of oil to be refueled in the tank truck by switching the lever, etc., and open the underground tank of the gasoline stand containing the same type of oil as the refueling hole. Check the display on the lid of the to confirm the lubrication.

[0003]

[Problems to be solved by the device]

 However, the operator who performs the refueling work must pay attention to which tank of the tank truck is used for refueling, and also to which refueling hole of the gas station to refuel. Then, remove the lid of the refueling hole, turn it over so that sand etc. do not adhere to the lid and place it on the ground, then operate the hose to refuel and try to select the tank with the lever of the tank truck. In addition, there is a possibility that the display on the lid may be forgotten or the user may misunderstand and misidentify it. If you put different types of oil in tanks that contain one type of oil, these oils will become unusable and you may have to clean the tank further. The present invention was made in order to solve the above problems. Whether the oil that is about to be refueled by removing the lid of the refueling hole is the same type as the oil in the refueling hole. The purpose of the present invention is to provide a lubrication hole that does not cause misunderstanding.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a cylinder provided on the tank side and a cylinder provided in the oil supply holes installed upward in a plurality of tanks arranged in parallel for containing different types of oil. The lid that is covered and locked, the step formed inside the cylinder, and the type of oil that is placed on the step and stored in the tank are displayed, and a string-like member is connected to the back of the lid. And a display plate.

[0005]

[Action]

 When the lid of the oil filler hole is removed and the fuel tank is about to be refueled, the display plate placed on the stepped portion of the oil filler hole is removed. At that time, the type of oil to be added to the tank by this oil supply hole is reconfirmed by the display plate.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The oil supply hole 1 of this embodiment is installed upward in an underground tank of a gas station. Underground tanks are installed in parallel to accommodate multiple types of oil such as kerosene, regular gasoline, or high-octane gasoline, and each has an oil supply hole. The tubular body 3 provided on the tank side is prevented from coming off when it is embedded in a concrete or the like by an anchor 5 protruding to the side surface. Further, ribs 7 which function as male screws are formed on the side surfaces. Further, a lock lever 11 for locking the lid 9 is attached. The lid 9 has a shape that covers the tubular body 3, and the type of petroleum to be refueled (kerosene in the figure) is displayed on the upper surface. Further, a pawl 13 having a substantially U-shaped cross section, which acts as an internal thread, is provided on the edge of the lid 9. Further, a convex portion 19 having a hole 17 to be inserted into the slit 15 of the lock lever 11 is formed. A U-shape or the like is hung on this hole 17. Further, the lid 9 and the tubular body 3 are connected by a chain 21.

A step portion 23 having a smaller inner diameter is formed inside the cylindrical body 3. On the display plate 25 that is sized to be placed on the stepped portion 23, the type of oil to be refueled by the refueling hole 1 is displayed. A leg 27 is formed on the back side of the display plate 25, and the leg 27 is inserted into a central hole of the step plate 23 and is stabilized. A chain 29 is attached to the upper surface of the display plate 25, and the other end of the chain 29 is fixed to the back side of the lid 9.

The operation of this embodiment will be described below. Workers of tanker trucks that bring oil to gas stations are determined which oil hole 1 of the gas station should be filled with which type of oil. When attempting to refuel kerosene through the refueling hole of this embodiment, first the lid 9 is removed. At this time, the removed lid 9 may be placed inside out on the concrete ground. After that, bring the hose of the tank truck to a nearby location and operate the lever to set which tank of the tank truck the kerosene will be supplied from. Next, when the tip of the hose is inserted into this oil supply hole 1 and the fuel is about to be supplied (FIG. 2), the display plate 25 mounted on the stepped portion 23 must be removed (FIG. 1). At this time, the display on the display plate 25 is checked again to confirm that the kind of oil to be supplied to the oil supply hole 1 is kerosene. Refueling is finally started by this confirmation.

In this way, after the type of oil to be refueled is identified on the display of the lid 1, the type of oil (kerosene in this case) is reconfirmed on the display plate 25. That is, it is possible to firmly confirm that the work of removing the lid 9 of a certain refueling hole 1 and selecting oil in a tank with a tank truck to refuel is proceeding without erroneous oil types. In addition, even if you forget or make a mistake during the work, you can notice the mistake at the final actual refueling scene. Therefore, it is possible to avoid the inconvenience that a large amount of oil is wasted by supplying different types of oil and that the inside of the tank needs to be cleaned.

After refueling, after returning the display plate 25 to the stepped portion 23 (FIG. 2), the lid 9 was put on the cylindrical body 3, and the rib 7 was engaged with the pawl 13 and rotated. After that, the lock lever 11 is rotated to insert the convex portion 19 into the slit 15, and a U-shaped lock (not shown) is hooked in the hole 17 to lock the lid. At this time, since the chain 29 of the display plate 25 is connected to the back side of the lid 9, even if the user forgets to return the display plate 25 (Fig. 1) and tries to put the lid 9 on, the chain 29 interferes. I can't cover it. Therefore, it is possible to prevent forgetting to return the display plate 25 to the inside. In addition, in the above-mentioned embodiments, the description has been made assuming that the fuel filling hole is installed in the underground tank of the gas station. The present invention can be implemented.

Although the display plate 25 has a hexagonal shape in the above embodiments, it does not necessarily have to be a hexagonal shape, and may have a triangular shape, a quadrangular shape, a pentagonal shape, or a polygonal shape including a heptagonal shape or more. In the above embodiments, the member connecting the display plates 25 was the chain 29, but in other embodiments, other string-shaped members such as wires may be used. The display on the display plate 25 is not limited to the Kanji characters shown in the drawing, but may be other characters, symbols, colors, or the like.

[0012]

【effect】

 As described above, according to the lubrication hole of the present invention, after the lid is removed from the lubrication hole, when the fuel tank is about to be refueled, the type of oil to be refueled is confirmed again on the display plate. Therefore, it is possible to reduce the mistake of accidentally refueling different types of oil.
