[Problem that the invention attempts to solve]

By the way, in the above-mentioned conventional technology, the second swivel pipe joint 22 connected to the proximal end of the refueling hose 23 in order to suspend the refueling hose 23 from the hose moving mechanism 15 has a base end portion. A right-angled pipe joint is used in which the center axis O ₁ -O ₁ of the tip 22A and the center axis O ₂ -O ₂ of the tip 22B are perpendicular to each other. Therefore, when attempting to extend the refueling hose 23 in the lateral direction with respect to the refueling device main body 3, that is, in the directions of arrows A and B in FIG. The second swivel joint 22 rotates around the tip 21B of the first swivel joint 21 in the state shown by the solid line in FIG. Therefore, there is a drawback that the extension range of the refueling hose 23 is limited, and the refueling range is substantially narrow.

On the other hand, when the refueling hose 23 is forcibly pulled in the direction of arrow A in FIG. , the second swivel joint 21 rotates in the direction of arrow C around the carrier 18 of the hose moving mechanism 15. Since the second swivel joint 21 is formed in a right-angled shape, the tensile force applied to the refueling hose 23 is increased to direct the tip 21B of the first swivel joint 21 in the direction of the tension. As shown by the dashed line in FIG. 7, the more linear force is applied to the refueling hose 23, causing it to bend abnormally, making it difficult to expand the refueling range much, and conversely, the refueling hose 23 The disadvantage is that it can cause damage more quickly.

The present invention was developed in view of the above-mentioned drawbacks of the conventional technology.Compared to the conventional technology, the refueling range can be expanded without increasing the number of pipe joints, and the refueling hose can be easily bent without applying excessive bending force to the refueling hose. It is an object of the present invention to provide a lubricating device that can improve the durability of a fuel tank.

[Means for solving problems]

The feature of the means of the present invention configured to solve the above-mentioned problems is that the second swivel joint provided between the first swivel joint and the hose is aligned with the central axis of the base end and the distal end. The reason is that the included angle with the central axis of the is formed so as to eliminate an obtuse angle.

[Effect]

The base end of the second swivel joint, which is rotatably connected to the front end of the first swivel joint, and the front end, to which the refueling hose is connected, have an obtuse angle between the center axes of each end. Since the hose is formed in this way, the tip can follow the direction in which the hose is pulled, and as a result, the hose can be straightened without being subjected to excessive bending force, and the range of oil supply is also expanded.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 3. Note that the same reference numerals are given to the same components as those of the prior art described above, and the explanation thereof will be omitted.

In the figure, 31 is the first swivel pipe joint 21
and a refueling hose 23, the second swivel fitting 31 is connected between the first swivel fitting 31 and the refueling hose 23.
It has a base end 31A rotatably connected to the distal end 21B of the swivel pipe joint 21, and a distal end 31B rotatably connected to the base end side of the refueling hose 23,
The central axis O ₃ -O ₃ of the base end 31A and the distal end 31
The included angle θ ₂ formed by the central axis O ₄ −O ₄ of B is different from the included angle θ ₁ of the second swivel joint 22 of the prior art,
The obtuse angle is set to about 135° in the example.

This embodiment is constructed as described above, and the basic operation itself for refueling the object to be refueled is no different from that of the prior art.

According to the refueling device of the embodiment, the refueling hose 2 is installed along the side plate 6D of the roof 6 of the refueling device main body 3.
3 is pulled to the maximum in the direction of arrow A in Figure 3,
Due to the tensile force, the second swivel joint 31 is connected to the carrier 18 via the first swivel joint 21.
Turn around in the direction of arrow C. However, the base end 31A of the second swivel joint 31 and the distal end 31B to which the refueling hose 23 is connected are connected to the center axis bearing line.
Since the included angle θ ₂ formed by O ₃ −O ₃ and O ₄ −O ₄ is set larger by θ ₃ than the included angle θ ₁ in the case of the conventional technology, the tip portion 31B can follow the pulling direction of the hose 23. , the refueling hose 23 can extend straight along the pulling direction. Moreover, since the second swivel joint 31 can swing to the maximum extent in the direction of arrow C using the carrier 18 as a fulcrum without applying unreasonable bending force to the refueling hose 23, the refueling range is greater than that of the conventional technology. can be expanded.

In addition, in the embodiment, the second swivel pipe joint 31
Although the first swivel joint 21 for connecting the two is described as being of a curved pipe type, the present invention is also applicable to a right-angled pipe type. In addition, two movable pipes 16A,
16B, the present invention can also be applied to an oil supply device in which a flexible hose is connected between the fixed pipe and the movable pipe joint 17 instead of the movable pipes 16A and 16B.

Furthermore, although the embodiment has been explained using a single-type hose mobile refueling device in which a refueling mechanism is provided only on one side of the refueling device main body, the present invention is a double-type hose mobile refueling device in which two sets of refueling mechanisms are provided. It can also be applied to

[Effect of idea]

The present invention is as described in detail above, and the second swivel joint provided between the first swivel joint supported by the hose moving mechanism and the hose is aligned with each central axis of the base end and the distal end. Since the included angle is an obtuse angle, the tip of the second swivel joint can easily follow the direction in which the hose is pulled and can turn to the maximum extent possible. As a result, the hose can be extended straight, so the range of oil supply can be expanded without increasing the number of pipe joints. Furthermore, since no excessive bending force is applied to the hose, the durability of the hose can be improved.
