Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a refueling device installed in a gasoline filling station for refueling automobiles and the like.

[Conventional technology]

There are two types of refueling equipment, such as a fixed type above the ground and a suspended type that hangs from a canopy. Of these, the fixed type above the ground has a lubricator housing installed on an island installed on the ground. An oil supply pipe communicating with an underground oil storage tank is set up in the housing, an oil supply hose outside the housing is connected to the oil supply pipe, and a nozzle hook of an oil supply nozzle attached to a tip of the oil supply hose is provided in the housing. ing.

In most cases, the connection point between the oil supply pipe and the oil supply hose is located at the top of the side surface or front and rear surface of the housing, and the nozzle hook is also provided slightly below the hose connection point on the side surface or front and rear surface of the housing. The nozzle hook is formed by forming a vertically long recess in the housing. The refueling nozzle is housed in the vertically long recessed nozzle hanger with the nozzle tip obliquely upward and nearly vertical.

In this way, the refueling nozzle is housed in the nozzle hook in a nearly vertical state, so remove the refueling nozzle from the nozzle hook,
Or, when returning to here, the refueling nozzle must be held vertically, which places a burden on the wrist of the worker holding the refueling nozzle, and the operability is required because the refueling nozzle is hooked off with the wrist folded. It is not good.

Also, when connecting the oil supply hose to the oil supply pipe on the side of the housing, the nozzle hook is provided on the front and rear surfaces of the housing so as not to interfere with the oil supply pipe etc. in relation to the processing of the oil supply pipe arranged inside. In addition, the mounting point at the base of the refueling hose was separated from the nozzle hooking position, and the workability when routing the refueling hose at the time of refueling work was not good.

Further, since the nozzle hook is constituted by a recess formed in the housing, the recess protrudes into the housing, and the arrangement positions of the lubrication equipment and the piping arranged in the housing are regulated. .

A refueling nozzle may be provided with a hand counter or a nozzle switch, but wiring such as a signal line connected to the hand counter or the nozzle switch is connected to a refueling hose in the same manner as a refueling pipe. Despite this, it was wired separately from the oil supply pipe.

For this reason, the arrangement of the oil supply pipe and the wiring path in the housing is complicated, and the assembling workability is not good.

The object of the present invention is to solve the disadvantages of the conventional example, to improve the operability of the operation of detaching and refueling the refueling nozzle, to be able to arrange the refueling equipment and piping in the housing without being restricted by the nozzle refueling, It is an object of the present invention to provide a lubricating device in which wiring such as signal lines and the like are collectively arranged in one place together with a lubricating pipe, so that the workability of assembling can be improved.

[Means for solving the problem]

In order to achieve the above object, the present invention has a column fixedly protruded from an upper portion of a housing containing a refueling pump, and a horizontal arm connected to a refueling hose at a tip from the column is projected.
In parallel with the horizontal arm, a refueling nozzle storage section having a built-in nozzle switch is provided on a support, and the support has a fuel supply pipe and a wiring disposed therein, and the horizontal arm partitions the inside to form a flow path and a wiring. A horizontal arm and a refueling nozzle storage portion projecting in both front and rear directions around a support column, and two The gist is to correspond to each refueling system.
