Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device, and when a refueling nozzle is hooked to a nozzle hook while the nozzle lever is locked in the open position, the nozzle lever The valve is configured to automatically return to the closed state using a lock release means that releases the lock, thereby eliminating the inconvenience of forgetting to close the refueling nozzle and causing the oil liquid to scatter during the next refueling. It is an object of the present invention to provide a refueling device that can reliably prevent such problems.

In recent years, at gas stations, for example, the scheduled amount of refueling is specified before refueling, and when the amount of refueling reaches the scheduled amount, a signal from a quantitative control device closes the metering valve in the refueling piping and refueling is started. Fixed-rate lubrication devices that automatically stop fueling have come into use.
However, this type of refueling device is configured so that the metering valve closes and stops refueling regardless of the nozzle valve of the refueling nozzle, so if the refueling operator is not careful,
Sometimes the user forgets to return the nozzle lever of the refueling nozzle to the closed position and leaves the refueling nozzle hanging on the nozzle hook with the valve open, without noticing the mistake.

In general, not only refueling devices with this kind of fixed-dose refueling function but also other refueling devices have a configuration in which the refueling pump drive motor is automatically started with electricity when the refueling nozzle is removed from the nozzle hook on the side of the refueling meter. has been done. Therefore, if the refueling nozzle is left open and hung on the nozzle hook as described above, as soon as the refueling nozzle is removed from the nozzle hook when refueling next time, oil liquid will be discharged and leak into the filling station. This method has disadvantages such as the fact that the oil liquid is scattered and there is a risk that the scattered oil liquid may catch fire and cause a fire or explosion.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings. 1st
The figure is a schematic front view of one embodiment of the oil supply device of the present invention, FIG. 2 is an enlarged view of the main part of FIG. 1, and FIGS. A Y-line vertical arrow view is shown.

In FIG. 1, the refueling device 1 has a ground-mounted configuration having a weighing machine 2 installed on the ground, and by removing the refueling nozzle 4 from the nozzle hook 3 on the side of the weighing machine 2, the refueling pump drive motor 5 is automatically energized and activated, and the oil supply pump 6 is driven. The refueling worker inserts the refueling nozzle 4 into the refueling port 8 of the vehicle 7,
The refueling nozzle 4 is opened. The oil pumped up from the underground tank 9 by the oil supply pump 6 passes through a flow meter 10 and further passes through the electromagnetic metering valve 12 in the oil supply pipe 11, and then flows from the oil supply nozzle 4 at the tip of the oil supply hose 13 to the oil supply port. Refueled within 8 days.

The metering signal of the flowmeter 10 is transmitted to the quantitative control device 14, and the control device 14 outputs a metering signal to the metering valve 12 when the amount of liquid to be supplied reaches a preset scheduled amount of liquid to be supplied, and the metering valve 12 is activated. Drive the valve closed.

In this way, the refueling device 1 automatically stops refueling when the refueling amount reaches the scheduled refueling amount. After finishing refueling, the refueling worker pulls out the refueling nozzle 4 from the refueling port 8, opens and closes the refueling nozzle 4, and then hangs it on the nozzle hook 3.

Here, the refueling nozzle 4 is as shown in FIG.
It has a grip part 15 having an oil flow path therein, and the valve is opened by gripping the grip part 15 and pulling the nozzle lever 16 to rotate it. The nozzle lever 16 is protected by an L-shaped lever guard 17, and the lever guard 17 is
In this embodiment, locking portions 18 and 19 are provided at two locations on one arm portion 17a that is connected to the arm portion 17a. The locking parts 18 and 19 lock the free end of the nozzle lever 16 when the valve is opened, and when the free end is locked with the locking part 18, the refueling nozzle 4 is fully opened,
When the refueling nozzle 4 is locked in the locking portion 19, the fuel nozzle 4 is in a half-open state.

In the case of this embodiment, the nozzle lever 16, which is rotatably provided, is installed with some play in the direction perpendicular to the direction of rotation.
The locking portions 18 and 19 are provided at such positions that the free end of the nozzle lever 16 is locked when the nozzle lever 16 is pulled and then shifted in a direction transverse to the direction of rotation. The lever guard 17 has a width dimension that can tolerate play of the nozzle lever 16. Note that this locking operation can be performed with one hand.

The nozzle hook 3 on which the refueling nozzle 4 is hung consists of a support plate 20 on which the arm portion 17a of the lever guard 17 is placed and supports it, and a pair of side plates 21 and 22 provided on both sides of the support plate 20. . Side plates 21 and 2
2 are spaced apart from each other by a dimension larger than the width dimension of the lever guard 17. When hooking the refueling nozzle 4 to the nozzle hook 3, first insert the tip of the discharge pipe 4a of the refueling nozzle 4 into the pipe hole 23 formed above the nozzle hook 3, and then support the arm portion 17a of the lever guard 17. Place it on the board 20. At this time, as shown in FIG.
The refueling nozzle 4 is inserted through a through hole 25 formed in the nozzle holder 3, thereby positioning and latching the refueling nozzle 4 to the nozzle hook 3 without falling off. Moreover, the engagement protrusion 24 is
Since the nozzle lever 16 is prevented from being displaced by protruding onto the arm 17a, the refueling nozzle 4 will not be opened while still being hooked to the nozzle hook 3 even if it is mistaken.

Here, 26 is a protrusion as a lock release means constituting the main part of the present invention, and the through hole 25 is connected to the engagement protrusion 2.
4 and place the lever guard 17 at a predetermined position on the support plate 20, the lever guard 17 is placed on the inner wall of the side plate 21 of the nozzle hook 3 so as to come into contact with the nozzle lever 16 and push the free end out of the locking parts 18 and 19. It is installed protrudingly. This protrusion 26 comes into contact with the nozzle lever 16 in connection with the latching operation when the refueling nozzle 4 is latched to the nozzle hook 3 while the nozzle lever 16 is latched to the latching portion 18 or 19. Shift this horizontally from the locking position, and this will cause nozzle lever 1
6 is released from the locking portions 18 and 19.

Therefore, even if, for example, you forget that the refueling nozzle 4 is in the open state after a fixed amount of refueling is finished, and you just hang the refueling nozzle 4 on the nozzle hook 3, the nozzle lever 16 will automatically close. Returned to valve position. In this case, the protrusion 26 releases the nozzle lever 16, and the nozzle lever 1
Since the engaging protrusion 24 engages with the through hole 25 after the nozzle lever 16 has completely returned to the valve closing position, for example, the nozzle lever 16 is locked to the engaging protrusion 24 and cannot be completely returned to the valve closing position. There will be no inconvenience if it disappears. Further, due to the engagement between the engagement protrusion 24 and the through hole 25, the nozzle guard 17 placed on the support plate 20 is stably positioned at a position where the nozzle lever 16 is unlocked.

In the refueling device 1 having the above-mentioned configuration, even when the refueling nozzle 4 is latched to the nozzle hook 3 with the valve open, the nozzle lever 1 is moved during the latching operation.
6 is released and the valve automatically returns to the closed state. Therefore, for example, as in a conventional oil supply device that does not have a lock release means, the oil supply nozzle 4 cannot be locked on the nozzle hook 3 without being closed after refueling. The danger of oil being discharged from the refueling nozzle 4 as soon as the refueling nozzle 4 is removed from the nozzle hook 3 during next refueling can be prevented in advance.

Note that a thick part for regulating the placement position is formed on the inner wall of the base of the side plate 22 relative to the support plate 20 so that the arm portion 17a is placed at a predetermined position on the support plate 20 instead of the engagement protrusion 24. The arm portion 17a is the side plate 21, 22
It may also be configured so that it is placed without play between the two.
Furthermore, it goes without saying that the base portion of the side plate 22 may be inclined at a predetermined angle instead of the thick portion.

Furthermore, by making the distance between the side plates 21 and 22 narrower than in the embodiment, making it slightly larger than the width of the arm part 17a, and by lowering the height of the side plate 22, the arm part 17a can be easily placed. It may also be configured so that it is carried out separately.

In the above embodiment, the number of locking portions that lock the free end of the nozzle lever 16 may be one, or three or more may be provided.

Further, in the above embodiment, the refueling device is not limited to the configuration in which the refueling pump 6 is driven when the refueling nozzle 4 is removed from the nozzle hook 3, but the refueling pump 6 is driven by closing a push button switch or the like. It may also be a configuration.

As described above, in the refueling device of the present invention, when the refueling nozzle is latched to the nozzle hook, when the nozzle lever is latched at the valve open position, the protrusion serving as the latching release means is activated in relation to the latching operation. Since the nozzle lever is automatically unlocked and the refueling nozzle is closed, there is no chance that the refueling nozzle will be hung on the nozzle hook while the valve is open. As with conventional refueling devices that do not have a latch release mechanism, refueling may be started without knowing that the refueling nozzle is in the open state, and the oil may leak from the refueling nozzle before the refueling nozzle is inserted into the vehicle's refueling port. There is no danger that the oil liquid scattered on the ground will catch fire or explode. It has features such as being able to position the nozzle lever at the unlocked position where the nozzle lever is spaced from the locking portion, and to stably support the nozzle lever so that it does not fall out of a predetermined mounting position.

Further, in the refueling device of the present invention, the nozzle lever is of a rotating operation type, and the refueling nozzle is provided with a locking portion that locks the free end of the nozzle lever, and after the nozzle lever is rotated to the vicinity of the locking portion, Since the nozzle lever is locked by shifting it laterally with respect to the rotation direction, the refueling nozzle can be opened with one hand during refueling, and the nozzle lever can be locked in the open state with only one hand. This can greatly simplify the refueling work.Furthermore, the unlocking means may be a protrusion provided on the side of the nozzle hook, or a rotating lever provided on the refueling nozzle. In this case, the nozzle lever can be unlatched very easily in connection with the latch operation of the refueling nozzle.
