Description

[Detailed Description of the Invention] The present invention relates to a refueling device used for supplying gasoline or the like to the tank of an automobile at a refueling station or the like.

In recent years, attempts have been made to make it possible to refuel as wide a range as possible with a hose of limited length even in refueling equipment installed on the ground in order to improve the efficiency of refueling operations. As one method, a type in which the hose leading out from the housing of the refueling device can be moved in the horizontal direction has been considered.

In this case, it is considered most suitable for leakage prevention to use a hose with a flexible pipe for the pipe line led out from the housing and connected to the inner end of the housing to which the refueling hose and nozzle are successively connected. It will be done. However, this hose needs to have oil resistance and pressure resistance, as well as abrasion resistance on the outer surface, making it expensive, so it is desirable that it be as short as possible. Additionally, there was a risk that a worker might hook the hose while refueling and the hose would move, causing the nozzle to come off the refueling port and discharging the oil.

In order to satisfy the above-mentioned requirements, the present invention allows for the use of a hose as short as possible, and has a simple structure that eliminates the risk of shortening the life of the hose due to excessive force being applied to the hose due to the movement of the outlet pipe. This project proposes a refueling device that can prevent this from occurring.A horizontal part of the housing is provided on the upper part of the vertical part of the housing that is set up on the ground, and a long hole is formed in the horizontal direction on the lower surface of the horizontal housing, and the direction of the long hole is The carrier moves along a rail attached to the carrier, and the carrier extends vertically through the carrier and can rotate horizontally relative to the carrier. A flexible tube is connected to the horizontally bent upper end. , an outlet pipe to which a refueling hose to which a nozzle is connected is connected to the lower end;
A plurality of recesses are formed along the elongated hole, and a projection is formed that is slidable relative to the outlet pipe and engages with the recess, and is always attached in the direction of engagement with the recess to prevent movement of the carrier. It is equipped with a handle for securing the carrier.

The illustrated embodiment will be described in detail below.

Reference numeral 1 denotes a housing of a refueling device installed on the ground G. A refueling hose 2 is suspended from an upper horizontal portion 1', and a nozzle 3 is connected to the tip of the refueling hose 2.

A display section 4 displays the amount of oil measured by a flow meter (not shown) housed in the vertical section 1'' of the housing 1.

Reference numeral 5 designates a housing portion for the nozzle 3, and reference numeral 6 designates a keyboard for setting the amount of oil to be supplied in advance, that is, a preset amount.

FIG. 2 shows a part of the cross section taken along the line A-A in FIG. 9' is attached, and a carrier 10 is provided which is movable in the horizontal direction by means of wheels 12 which can each roll about an axis 11 using the rails 9, 9' as guides.

Reference numeral 13 denotes a lead-out pipe, the upper end of which is bent in the horizontal direction and connected to one end of a flexible hose tube 15 through a connector 14, and the other end of this hose 15 is also connected to a flow meter through a connector 16. (not shown)
It extends from the outlet of the housing 1 and is connected to a steel pipe 17 fixed to the housing 1.

The vertical portion 18 of this outlet pipe 13 is connected to the carrier 10.
On the other hand, the lower end 19 of the lower end 19 passes through the elongated hole 8 and extends to the lower outside of the horizontal portion 1', and is connected to the oil supply hose 2 by a connector 20.

That is, the oil measured by the flow meter passes through the steel pipe 17, the hose 15, the outlet pipe 13, and the oil supply hose 2 in this order, and is supplied from the nozzle 3.

Reference numeral 21 denotes a handle, which is slidably fitted loosely into the vertical portion 18 of the outlet pipe 13, and is normally fitted with a spring 24.
is urged upward by the elasticity of Two protrusions 22, 22' are formed on this handle 21, and these protrusions 22, 22' are formed in each one of a number of recesses 23, 23' formed in the rails 9, 9', respectively. By fitting into the outlet pipe 13,
In other words, the carrier 10 is prevented from moving in the horizontal direction.

25 is a steel ball interposed between the contact surface between the carrier 10 and the outlet pipe 13, and 26 is a ring inserted between the spring 24 and the connector 20, both of which prevent the rotation of the outlet pipe 13 with respect to the carrier 10. It has the effect of smoothing out the process.

In the above configuration, when moving the refueling hose 2 horizontally with respect to the horizontal portion 1' of the housing 1, as shown in FIGS. lower. Then, the protrusion 22 of the handle 21,
22' are recesses 23, 2 formed in the rails 9, 9'.
3', and the handle 21, that is, the outlet pipe 1
3 horizontal movements are possible.

When the outlet tube 13 is moved to the required location and the handle 21 is released, the handle 21 is moved by the spring 2.
The projections 22, 22' are displaced upward by the elasticity of 4.
are fitted into the recesses 23, 23', and the outlet pipe 1
3 horizontal movement is prevented.

By doing this, the outlet pipe 13 cannot be moved except when necessary, and an accident can be prevented in which the nozzle 3 inserted into the car comes off due to an operator pulling on the refueling hose 2 during refueling. I can do it.

Next, the outlet tube 13 when the outlet tube 13 is moved
The conditions of the hose 15 and the hose 15 are compared in FIG.

When the position of the carrier 10 moves from the solid line position to the two-dot chain line position, since the length of the hose 15 is limited, the way the hose 15 bends changes, and accordingly, the outlet pipe 13 does not apply unreasonable force to the hose 15. Rotate in the direction.

As a result, the life of the hose is extended compared to when the outlet pipe 13 does not rotate, and the length of the expensive hose can be shortened.

Note that the present invention is not limited to this embodiment. That is, the structures of the rails 9, 9' and the carrier 10 may be other structures that provide similar effects.

With the structure described in detail above, the structure is simple and can be manufactured at low cost.Since there is no rotating seal part, there is no fear of oil leakage, and it is possible to refuel a wide range with a limited length of the refueling hose. This provides a refueling device that can prevent accidents caused by the hose moving.
