  As shown in FIG. 8, when the unlocking state is released by the release lever 35, the opposite end of the locking lever 31 opposite to the locking lever rotation shaft 31 c is in contact with the upper and lower intermediate positions of the holder lower portion 23. A notch 31e is formed to avoid this. In addition, although this notch part 31e is comprised by the opening with which the circumference | surroundings were enclosed (concave shape), for example, a thing with an open upper end may be sufficient. However, the shape in which the periphery is surrounded as in the present embodiment is easier to ensure the strength.

-Operation of the refueling nozzle storage device-
Next, the operation of the oil supply nozzle storage device 20 according to the present embodiment will be described.

  First, in order to fix the fuel supply nozzle 10, the grip portion 14 of the fuel supply nozzle 10 is held with one hand, and the locked portion 12a of the trigger protection frame 12 is engaged with the locking portion 31a while the nozzle tip 10b is inserted into the nozzle tip fixing portion 22. Is pushed into the holder lower part 23 while being brought into contact with.

  At this time, since the near portion 31f of the locking portion 31a is inclined toward the near side, the locked portion 12a can be pushed in smoothly while being brought into contact therewith.

  Since the locking portion 31a (locking lever 31) is pulled by the tension coil spring 31d, the locked portion 12a is inserted so as to resist the pulling force of the tension coil spring 31d. When the locked portion 12a passes the tip of the locking portion 31a, the locking portion 31a is pulled by the tension coil spring 31d to return to the original locked position, and as shown in FIG. 7, the locking portion 31a. Becomes a state where the trigger protection frame 12 is locked.

  In this state, the locking projection 23a fits into the nozzle side locking hole 13, and the nozzle tip fixing portion 22 cooperates to fix the fuel supply nozzle 10 in the retracted position. In this way, it is possible to easily store and fix the fuel supply nozzle 10 simply by pushing it in with one hand.

  On the other hand, in order to remove the fixed oil supply nozzle 10, the gripping portion 35c is operated in the direction of arrow B (see FIG. 8). As a result, the engaging portion 31a can be rotated from the locked position to the unlocked position against the tensile force of the tension coil spring 31d with a small force by the lever principle. As a result, the locked state of the locking portion 31a and the locked portion 12a is released, so that the oil supply nozzle 10 is pulled toward the front while the release lever 35 is operated, and is removed from the oil supply nozzle storage device 20. In this way, the fuel supply nozzle 10 can be easily removed simply by operating the release lever 35.

  By the way, the oil supply nozzle storage device 20 can also store the oil supply nozzles 110 having different shapes as shown in FIGS. 13 and 14. In this fueling nozzle 110, the shape of the nozzle side locking hole 113 is rectangular, and the shape of the trigger 111 and the distance from the locked portion 112a to the nozzle tip 110b are also different.

  Therefore, first, the nozzle fixing hole 30b that matches the size of the fueling nozzle 110 is selected, and the mounting position of the nozzle tip fixing portion 22 is adjusted.

  Next, the fuel nozzle 110 is stored in the fuel nozzle storage device 20.

  As in the above, holding the grip portion 114 of the oil supply nozzle 110 with one hand and inserting the nozzle tip 110b into the nozzle tip fixing portion 22, the locked portion 112a of the trigger protection frame 112 is brought into contact with the locking portion 31a (front portion 31f). When pushed into the holder portion 21 while being in contact, the shape of the nozzle side locking hole 113 is larger than that of the oil supply nozzle 10, but the locking projection 23a is similarly fitted therein.

  As described above, in the present embodiment, once the fuel supply nozzles 10 and 110 are stored and fixed, the locked portions 12a and 112a are locked to the locking portions 31a and detached unless the release lever 35 is operated. Absent. In addition, by making the latch lever 31 and the release lever 35 separate, it is possible to make the structure easy to release using the principle of the lever and to lock the release lever 35 while narrowing the rotation range. Since it can cancel | release, it can reduce in size in a rotation direction.

  Furthermore, the nozzle tip fixing portion 22 can stably hold the fuel supply nozzle 10 in cooperation with the holder portion 21 and is difficult for dust and the like to enter from the nozzle tip 10b.

  In addition, by setting the center of gravity of the locking lever 31 described above, the locking lever 31 is maintained in the locked position even if it does not function due to the tension coil spring 31d coming off, etc., so that the oil supply nozzle 10 is unintentionally caused by running vibration. It can be prevented from falling off.

  Further, in the present embodiment, the rotation range of the release lever 35 can be widened by the cutout portion 31e, and the rotation state of the locking lever 31 and the release lever 35 can be confirmed simply by looking inside the cutout portion 31e. The fixed state of the fueling nozzle 10 can be easily confirmed.

  Therefore, according to the fueling nozzle storage device 20 according to the present embodiment, the fueling nozzle 10 can be easily fixed and removed, and the fueling nozzle 10 is not unintentionally detached unless the release lever 35 is operated. Can do.

  That is, in the above embodiment, the oil supply nozzle storage device 20 is attached to the hose winding device 6 of the tank truck 1, but may be attached to any position of the vehicle body 2. Moreover, you may attach not only to the tank truck 1 but to the oil supply apparatus etc. which were mounted on the ground. However, in the present invention, since the locking lever 31 is surely kept in the locked state, the effect is particularly exerted in the configuration in which the vibration during traveling is transmitted to the fuel supply nozzles 10 and 110 as in the tank truck 1.

  Moreover, in the said embodiment, although the lock mechanism main body 30a was provided in the right side of the holder lower part 23 seeing from the front, you may provide in the left side.

  Moreover, in the said embodiment, although the latching lever 31 and the cancellation | release lever 35 were comprised separately, you may form integrally. In this way, the number of parts is reduced and assembly is easy. However, in this case, it is necessary to ensure a large rotation range at the time of release.

  Further, the shape of the nozzle side locking holes 13 and 113 is not limited to that of the above embodiment. In short, when the oil supply nozzle is placed on the oil supply nozzle storage device 20, the engagement protrusion may be engaged with the nozzle-side engagement hole.

  Furthermore, in the said embodiment, although the locking lever 31 supported so that rotation was possible was illustrated and demonstrated, it may replace with this and may be a locking lever guided so that sliding movement was possible, for example.
