[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a housing structure for a refueling machine in which a part of the housing is composed of a cover that can be opened and closed, and in particular, the present invention relates to a housing structure for a refueling machine that includes a cover that can be opened and closed, and in particular, the cover can be opened and closed without completely removing it from the frame. The present invention relates to a housing structure for a refueling machine that allows for

[Prior Art] A refueling machine normally placed inside a gas station is equipped with an indicator on the outside of its housing to display the amount of refueling each time to customers or employees. The meter is configured to display zero each time the fuel is refilled using a nozzle switch. Furthermore, an integration display meter is provided within the housing to integrate and display the respective amounts of oil supplied. This integrated display meter is provided once a day when the store is closed to check the amount of refueling for that day. . However, in conventional refueling machines, the cover had to be completely removed from the frame to check the display on the totalizer. As a result, there was no place to stand the cover, or even if there was, the cover would fall over and get scratched, and it took a lot of time to check the display on the display meter.

Furthermore, in the past, since the totalizer was provided in close proximity to the refueling amount display meter installed on the top of the refueling machine to display the amount of refueling, it was inconvenient that, for example, the sales status could be known to people in the same industry. Therefore, it is preferable that the oil supply amount indicator be installed in a place that is easily visible from the outside, and that the totalizer be as hidden from view as possible from the outside.

Furthermore, when the refueling amount indicator becomes an electric type, the totalizer is often a mechanical type in case the refueling amount cannot be displayed due to a power outage or failure of the electric indicator. If the totalizer is mechanical, it will be necessary to provide a mechanical transmission means different from the electrical transmission means between the oil supply level indicator and the flow meter, so if it is installed close to the oil supply level indicator, the communication between them will be reduced. becomes difficult. In the case of conventional mechanical display meters, the transmission means are the same, so there is no mechanical problem even if they are placed close together.
There are problems as mentioned above.

Generally, in order to facilitate inspection and maintenance of the equipment installed inside the case of a refueling machine, the technology of providing a side-opening lid that rotates horizontally on the case was developed, for example, by Jitsukasho.
It is described in Publication No. 49-106910. However, when opening horizontally like this, you cannot see inside the case unless you rotate the lid at least 45 degrees, and if you place an item in front of the lid, it will get in the way when opening and closing the lid, which takes up space. limited to.
In addition, for example, a technology for opening vertically around an axis extending in the horizontal direction as a rotating device was developed in 1985.
-Described in Publication No. 125595. However, when trying to apply this technique to the lid of a refueling machine, it is impossible to hold the cover in a half-open state, and therefore, the cover must be constantly held with one hand, and the hand may come off. It is dangerous if the cover falls down.

[Object of the Invention] Accordingly, an object of the present invention is to provide a housing structure for a refueling machine that allows the totalizer inside the case to be safely read with the cover half-open.

[Structure of the Invention] The housing structure of the refueling machine according to the present invention houses a display meter in the upper housing, and a motor, a pump, a flowmeter, and a totalizer connected to the flowmeter in the lower housing, with the display surface facing upward near the flowmeter. A cover that can be opened and closed from above is provided on the front surface of the lower housing, and locking means that can hold the cover in a completely closed state relative to the lower housing body are provided, and the cover is attached to the totalizer. It is formed so that it engages and holds the cover in a partially open state until the display surface can be seen from above, and when the cover is closed from the completely open state, it escapes downward when it engages with the cover and does not impede the progress of the cover. A cover locking means is provided, the locking means has a locking arm that can be engaged with a bent end portion of an upper arm member of the lower housing, and the cover locking means is provided on the cover and has a rear bent portion. The stopper part is provided in the middle of the arm member.

[Description of the function and effect of the invention] Therefore, for example, when checking the amount of refueling for the day when the store is closed, the locking means is removed and the cover is partially opened so that the display surface of the totalizer can be seen. The display can be read immediately by holding it with a stop means and looking into the display surface from above. At gas stations, lighting equipment is installed in the canopy, and even if there is no canopy, the area around the gas tank is bright because of the lighting from above, and the display screen is illuminated by light from above, so there is no need to use a flashlight. I'm done. Furthermore, since the cover is locked by the cover locking means, it will not fall over and is safe.

Furthermore, since the cover can be viewed visually when it is half-open, even if there is an item in front of the cover, it will not get in the way.

Therefore, according to the present invention, it is possible to check the integration display very easily and quickly.

In this way, the locking means normally prevents the user from seeing the totals, so others cannot see the sales status, and if they wish to check the totals, they can easily do so.
