Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a fueling nozzle with an indicator for displaying a fueling amount.

[Prior Art] Conventionally, it is known that a refueling nozzle is provided with an indicator so that a worker can immediately know the refueling amount during refueling work. However, since the refueling nozzle is connected to the refueling hose via the swivel, there is a problem with the wiring of the signal line connected to the indicator. For example, in the prior art, since there is a swivel provided in the barrel of the refueling nozzle, it is difficult to connect the swivel if it is wired inside the pipe, and if the outside of the refueling hose is wired, It may get in the way or get caught and get disconnected.

For example, in JP-A-58-183494, an electric wire having a curl portion is wired outside the oil supply hose, but since the electric wire is wired so as to straddle the nozzle body, it hinders the operation.

[PROBLEMS TO BE SOLVED] Therefore, an object of the present invention is to provide a refueling nozzle with an indicator, which does not interfere with refueling work even if a signal line is provided outside and is not likely to be disconnected.

[Means for Solving the Problem] According to the present invention, in a fueling nozzle with an indicator attached to the tip of a refueling hose provided in a hose accommodating device provided in a canopy so as to be able to move up and down, an indicator is provided on the body of the nozzle body. Mounting, the side of the body is connected to the elbow via a first swivel joint, the elbow is connected to a refueling hose via a second swivel joint, and their first and second swivel joints are attached. Each of them is provided with a rotation restricting means, and a connector provided with a hose lifting switch is attached in the middle of the refueling hose, and a signal line extending from the connector to the indicator along the refueling hose has a curl portion in the middle, The gap between the refueling hose and the body is straight.

[Explanation of Action and Effect] Therefore, although the nozzle body is rotated by the first and second swivel joints to improve the operability in a so-called ceiling-suspended filling station, the nozzle body is connected to a connector in the middle of the filling hose. Since it is connected to the indicator provided on the nozzle body by the signal line wired to the outside,
And when the second swivel joint swivels around, the signal wire winds around the refueling hose and the elbow. Therefore, the rotation restricting means prevents the signal line from being wound. However, it usually takes about one revolution (about 340
Since it can rotate, the expansion and contraction of the signal line at that time is guaranteed by the curl portion.

The curl portion requires a certain space because of the coil shape.
However, although the operability is good in the refueling nozzle in which the swivel joint is provided on the side of the body of the nozzle body, the wide body makes the gap between the body and the refueling hose narrow.
Since the cylinder tip of the fueling nozzle is thin, the gap between the cylinder tip and the fuel supply hose is relatively wide. Therefore, in the present invention, the signal line between the refueling hose and the body portion is a straight line, and the curl portion is not pinched between the body portion and the refueling hose even when the refueling nozzle rotates.

As described above, according to the present invention, the worker can perform the refueling work while looking at the display meter without the signal line to the display meter hindering the operation of the refueling nozzle, so that the refueling work efficiency is improved.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a refueling device equipped with a refueling nozzle embodying the present invention. An office B is provided on site A of the refueling station, and a hose storage device 2 is provided on a canopy 1 provided above the refueling station. Has been. A hose reel 4 driven by a motor 3 is stored in the hose storage device 2, and an oil supply hose 5 is wound around the hose reel 4. A refueling nozzle 12 is provided at the tip of the refueling hose 5, and a display meter 20 for displaying the refueling amount is attached to the refueling nozzle 12.

On the other hand, in the oil supply pipe 6 extending from an oil storage tank (not shown),
A pump 7 is provided, and an oil supply pipe 8 connected to the oil supply hose 5 is connected to the pump 7, and the oil supply pipe 8 is provided with a flow meter 9 equipped with a flow rate pulse transmitter 9p. The flow rate pulse transmitter 9p is connected to the control unit 10 which is grounded in the office B, and the control unit 10 calculates the refueling amount based on the flow rate pulse signal and displays the refueling amount display 11 attached to the side wall of the office B. The amount of refueling is displayed on the display, and the amount of refueling is displayed on the display 20 as will be described later.

FIG. 2 shows an example of the refueling nozzle 12 embodied in the present invention. The refueling nozzle 12 includes a body 13 as a main body and a body 13
It is composed of a cylinder tip portion 14 which extends straight from one end portion and whose tip bends slightly downward, and a grip portion 15 which extends obliquely downward from the other end portion of the body portion 13.

An elbow 16 is connected to the center of the side portion of the body portion 13 via a swivel joint 19, and the elbow 16 is further connected to an oil supply hose 5 via a swivel joint 18.
A stopper 17a which is a rotation restricting means for restricting the rotation is shown at 18.
And 17b are provided. 22 is swivel joint 19
Is a stopper pin, and is planted in the body 13. From the middle of the upper surface of the body portion 13 to the rear end portion thereof, a display meter generally designated by 20 is attached. This indicator 20 has a known electric circuit built therein.

As shown in FIGS. 3 and 4, the refueling hose 5 side and the body portion 13 side of the elbow 16 are rotatably connected via swivel joints 18 and 19, respectively. Is rotated and regulated by the stoppers 17a and 17b as described above, and the body portion 13 side is a pin embedded in the body portion 13.
22 constitutes a rotation restricting means, and the elbow is attached to the pin 22.
The side surfaces of 16 are abutted and locked.

The display unit 20 is provided with a display unit 20a for displaying the number of the refueling device and a display 20b for displaying the refueling amount. On the other hand, refueling hose 5
A connector 23 is attached to the connector 23, and the connector 23 is provided with a reset switch SW1 for continuous oil supply and a hose lift switch SW2.

The traffic light W1 extending from the control device 10 in the office is wired in the refueling hose 5 up to the connector 23. Then, at the connector 23, the signal line W2 is connected to the signal line W2.
Is wired outside the fueling hose 5 and is connected to the indicator 20. The signal line W2 wired outside has a dense coil-shaped curled portion C in the middle thereof.

As can be seen from FIG. 3, the cylinder tip portion 14 and the grip portion 15 are relatively thin, and the body portion 13 is relatively thick. Therefore, when the refueling nozzle 12 rotates at the swivel joint 19,
The space 1 between the body 13 and the elbow 16 and the swivel joint 18 is relatively narrow, and the cylinder tip (or the grip when the swivel joint 19 rotates about 180 degrees from the state shown in FIG. 3) and oil supply The space L between the hose is relatively wide. That is, the curl portion C has a narrow space l in the range of twice the length r from the rotation center O of the swivel joint 19 to the longer end portion (lower end in the illustrated example) of the body portion 13. Is provided outside the length r so that it does not interfere with the part of the fueling nozzle 12, particularly the body part 13.

Therefore, at the time of refueling work, the elbow 16 is rotated with respect to the refueling hose 5 by the swivel joint 18, and the refueling nozzle 12 is rotated with respect to the elbow 16 by the swivel joint 19, and the movement of the refueling nozzle 12 causes the indicator 20 to move. Although the length between the mounting portion of the wire W2 and the mounting portion of the connector 23 changes, the change can be absorbed by the curl portion C.
Further, because of the curl portion C, the signal line W2 is in a stretched state and does not dangle, so it does not interfere with the refueling work and is not damaged.

[Effects of the Invention] As described above, the present invention has the following excellent effects.

(I) Since the curl portion is provided on the signal line between the connector and the indicator, a change in length can be absorbed, and even if the signal line is caught by something, the curl portion can sufficiently compensate.

(Ii) Since the signal line is stretched, it does not dangle, does not interfere with the operation, and is not damaged.

(Iii) The curl portion is provided at a position where it does not interfere with the wide body portion, and the signal line is a straight line at the body portion, so the curl portion does not interfere with the rotation of the refueling nozzle.

(Iv) Therefore, the refueling work efficiency can be improved.
