Description

[Detailed Description of the Invention] This invention relates to a refueling nozzle in which a cushioning material is attached to the end of the grip.

Conventionally, the hanger-type refueling nozzle, which has been widely used at gas stations, etc., is a system in which a standman remotely controls a refueling hose lifting device installed at a high place, lowers the refueling nozzle to a position where it is easy to refuel, and then starts refueling. It is something that can be entered.

Therefore, there is a predetermined distance between the lowered position of the refueling nozzle and the remote control panel of the lifting device, and the operator reciprocates between this distance each time refueling work is performed.

Therefore, in situations where refueling operations must be performed frequently, remote control tends to be cumbersome, and there are many cases where refueling operations are performed by letting out the refueling hose by intuition without checking the descending status of the refueling nozzle.

In such a case, as a matter of course, the descending refueling nozzle cannot be stopped at a fixed position, and if a mistake is made in judgment, the refueling nozzle may crash into the floor and be damaged. There was a risk of gasoline etc. leaking outside and causing a fire hazard.

This idea was made in view of the above circumstances, and its purpose is to have a plurality of hose connection holes, and when used as a refueling nozzle of a hanging refueling device, the end of the grip In the case of a refueling nozzle that is located below, a cushioning material is provided integrally with the stopper that closes the hose connection hole provided at the end of the grip, and the refueling nozzle accidentally crashes into the floor when lowered. The purpose is to absorb and alleviate the impact of a collision and prevent damage to the refueling nozzle.

An embodiment of this invention will be described in detail below based on the drawings.

FIG. 1 is a diagram for explaining the mounting state of a refueling nozzle used in a hanging type refueling device and the configuration of an elevating device.

What is indicated by the reference numeral 1 in the figure is a refueling nozzle, and this refueling nozzle 1 is connected to a refueling hose 2 via a liquid-tight rotary joint to a valve mechanism section to be described later. The height and low position can be adjusted, and the feeding and hoisting of the refueling hose 2 is performed by a lifting device 3 attached to the ceiling, and this lifting device 3 can be controlled remotely by a switch 5 attached to the tip of a lead wire 4. I'm starting to get it.

FIG. 2 is a diagram for explaining the configuration of the essential parts of this invention in the oil supply nozzle 1.

As is clear from this figure, the refueling nozzle 1 used in this invention is roughly composed of a valve mechanism part 1a, a discharge pipe 1b and a grip part 1C provided between the valve mechanism part 1a,
Connection holes 6 a and 6 b for the refueling hose 2 are provided at two locations: the valve mechanism portion 1 a and the end portion of the grip portion 1C.

This refueling nozzle can be used by appropriately changing the connection position of the refueling hose 2 depending on the refueling mode, for example,
In the case of a ground-mounted refueling device, the connection hole 6b is used, and in the case of a hanging type refueling device, the connection hole 6a is used.

In the figure, reference numeral 7 denotes an L-shaped liquid-tight rotary joint, through which the refueling hose 2 is connected to the connection hole 6a, and the refueling nozzle 1 is attached to the refueling hose 2 so as to be relatively rotatable.

A valve body 9 that is opened and closed by a lever 8 is provided within the valve mechanism portion 1a.

A plug 10 for closing the connection hole 6b at the end of the grip portion 1C is fitted.

By the way, the stopper 10 in this invention is made of a heavy member and has a knob-like shape, and the outer circumferential surface exposed to the outside is made of an elastic member having an appropriate thickness, such as rubber 11. covered with a cushioning material made of

The operation of the oil supply nozzle 1 will be explained below.

Since the refueling nozzle 1 has a plug 10 fitted into the connection hole 6b at the end of the grip portion 1C, this plug 10 serves as a weight.
In the suspended state, the refueling nozzle 1 rotates relative to the refueling hose 2 through the joint 7, keeping the rear end of the refueling nozzle 1 facing downward (see Figure 1), and when not refueling, the discharge pipe 1
Prevent oil from dripping from b.

Therefore, even if the remote control switch 5 is operated incorrectly when lowering the refueling nozzle 1 and the refueling nozzle 1 falls as shown in FIG. 1 and crashes into the floor, the rear end of the refueling nozzle 1 will always be It ends up falling, facing downward, and crashing into the floor.

On the other hand, during this collision, the rubber 11 that covered the surface of the stopper 10
absorbs and alleviates the impact applied during a collision, so that it does not directly impact the refueling nozzle 1 itself.

The refueling nozzle 1 is thus protected from damage.

In the above embodiment, the entire surface of the stopper 10 is covered with the rubber 11, but for example, the lower end of the stopper 10 may be formed flat and a rubber body formed into a semicircular arc may be attached to this part. Various modifications are possible, and the present invention is not limited to the above-mentioned configuration as long as the refueling nozzle is constructed by attaching a cushioning material made of an elastic member to the externally exposed portion of the stopper 10.

Further, in the above embodiment, the refueling nozzle 1 is maintained in the state shown in FIG. 2 by the weight of the stopper 10, but it can also be maintained in the state shown in FIG. 2 by the frictional force in the rotational direction of the joint 7.

Furthermore, in the above description, a case has been described in which the refueling nozzle 1 of this invention is applied to a hanging type refueling device, but the grip part 1
By removing the plug 10 that closes the hose connection hole 6b at the C end and connecting a refueling hose there, the present invention can be easily applied to a ground-mounted refueling device.

Since this invention has the above-described structure and operation, it produces the effects described below.

(1) In the case of a hanging refueling system, even if the refueling hose accidentally extends too long and the refueling nozzle hits the floor, the refueling nozzle will fall with the rubber-covered stopper at the lowest position. All the impact of a collision is absorbed and mitigated by the rubber.

Therefore, the refueling nozzle can be spared from damage due to a collision.

Therefore, gasoline and the like will not be inadvertently leaked out, and dangers such as fire can be prevented, making it extremely practical.

(2) Two hose connection holes are provided so that it can be applied to either a hanging type or a ground-mounted type, and a cushioning material is integrally attached to the plug itself, which can be attached as appropriate depending on the type of use. Because of this, even during manufacturing, compared to the case where cushioning material is attached to other parts of the refueling nozzle, it is easier to connect the refueling hose by selecting the hose connection hole, regardless of the difference in the above-mentioned dual-use configuration. It is possible to standardize the manufacturing process for both, and work efficiency during manufacturing can be improved.

When used in a hanging refueling device, it is necessary to plug the hose connection hole at the end of the handle, but by simply plugging it, a cushioning material is automatically installed. This corresponds to the type of use.

Therefore, it is not necessary to take the precaution of attaching a cushioning material to the grip portion.

(3) Furthermore, even if the elastic material as a buffer provided in the refueling nozzle wears out or deteriorates due to use or aging, it is easy to change the stopper without disassembling the refueling nozzle itself. can be exchanged for.
