Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a refueling device configured to constantly urge a refueling hose upward.

(Prior art) Conventionally, this type of refueling device has a mast section provided above the main body, a traction mechanism that utilizes the elasticity of a spring, etc. on the mast section, and a refueling hose connected to the traction mechanism. The system is constructed so that it is constantly pulled upward, reducing the perceived weight of operating the refueling nozzle during refueling operations.

(Problems to be Solved by the Invention) However, in this conventional refueling device, the mast portion to which the traction mechanism was attached was fixed to the main body. Therefore, the middle part of the refueling hose is always towed in one direction, and when extending the refueling hose in a direction other than the direction in which it is being towed, the problem is that the cable gets wrapped around the mast and cannot be pulled out smoothly. It was hot. If the rope wraps around the mast, it will require extra force to pull the refueling hose, and many problems will occur, such as the range of refueling in the direction opposite to the direction in which the rope is being towed. It is.

The present invention was devised to solve the above problem, and by providing the traction mechanism so that it can rotate horizontally with respect to the main body, the cable does not wrap around the mast part, and therefore, the problem caused by this It is an object of the present invention to provide a refueling device that can solve various problems such as the operability of a refueling nozzle, the durability of a cable, and the durability of a hose.

(Means for Solving the Problems) The refueling device of the present invention includes a refueling hose whose base end is connected to the refueling device main body via a joint and a refueling nozzle is connected to the distal end, and one end thereof is connected to the refueling hose. The refueling hose is constantly pulled upward by the connected cable and a rule provided on the refueling device main body above the joint, to which the other end of the cable is connected and biased in the winding direction. In the refueling device, the towing mechanism is provided in a housing that is rotatably mounted in a horizontal direction with respect to the main body of the refueling device, and an opening for pulling out the cable is formed in the housing. , the traction mechanism is rotated in response to movement of the refueling nozzle to a refueling work position.

(Function) With the above configuration, when the refueling nozzle is moved to perform refueling work, the direction in which the cable is pulled out from the traction mechanism is regulated by the opening in the casing. The housing is rotated so that the opening faces the refueling work position of the refueling nozzle, and the traction mechanism is also rotated accordingly, so that the cable can be smoothly pulled out while facing in the direction of the refueling work position. can.
