[0002]

2. Description of the Related Art Conventionally, as a device of this type, there has been known a device for supplying air into a pressure tank by using a commercially available bicycle inflator. In this conventional device, an air inlet is provided in the pressure tank, an inflow valve is provided in the air inlet, and when replenishing the air in the pressure tank, a mouthpiece for introducing the air is attached to the air inlet of the pressure tank. Moreover, when measuring the air pressure in the pressure tank, it was necessary to remove the mouthpiece of the air tank from the air inlet of the pressure tank and then connect an air gauge to the air inlet.

[0003]

In the above conventional example, the air pressure in the pressure tank is measured with an air gauge, and if the air pressure does not reach the specified value, the air gauge is connected to the air inlet. It was necessary to perform a series of work of sending air into the pressure tank by inflating 200 times, resulting in poor workability and labor.

Further, in a commercially available inflator, the inflator cannot be connected to the inflow port of the pressure tank in a state where the inflator is erected on the floor surface. It is necessary to hold the inflator and operate the handle part of the inflator with the remaining one hand, and in this respect also, the workability of the inflator is extremely poor.

A first object of the present invention is to provide an air replenishing device for a pressure tank of a pressurizing pump, which can carry out an inflating work efficiently and easily.

A second object of the present invention, together with the first object, is to provide an air replenishing device for a pressure tank of a pressurizing pump which can replenish air to the pressure tank in a short time without requiring labor. It is in.

[0007]

[Means for Solving the Problems] The first object is to provide a mounting table mounted on the floor, a pump main body installed on the mounting base, and a pressure tank disposed above the pump main body.
A pressurizing pump having at least a control panel arranged around the pressure tank, wherein the pressure tank of the pressurizing pump is provided with an air inlet port, an air inlet port is provided at the air inlet port, and An air replenishing device that is connected to the inflow port and replenishes air into the pressure tank through the inflow valve is provided, and the air replenishing device includes an air pump body that can stand upright on the floor and the air pump. And a hose connected to the main body. Air vent valve,
By providing a stop valve and a pressure gauge, and further, setting the hose to a length such that the hose end can be connected to the air inlet while the air pump body is erected on the floor. Is achieved.

According to this structure, air is sent to the pressure tank until the specified pressure value is reached while the air supply device is erected on the floor and while confirming the air pressure in the pressure tank with the pressure gauge. In addition, in the unlikely event that air is excessively sent into the pressure tank, the air pressure inside the pressure tank can be adjusted by opening the air vent valve to remove the air inside the pressure tank.

The second object is to mount the table on the floor, the pump body installed on the table, the pressure tank disposed above the pump body, and the surroundings of the pressure tank. A pressurizing pump including at least a control panel provided, wherein an air inlet is provided in a pressure tank of the pressurizing pump, and an inflow valve is provided at the air inlet,
An air replenishing device connected to the air inflow port and replenishing air into the pressure tank through the inflow valve is provided, and the air replenishing device includes an air compressor main body that can be installed on a floor surface and the air compressor body. A hose connected to the compressor body, a pressure reducing valve, a stop valve and a pressure gauge are provided on one end side of the hose to which the air compressor body is connected, and the other end side of the hose is connected to the air flow. This is achieved by setting the length of the hose so that the hose can be connected to the air inlet while being connected to the inlet and the air compressor body is installed on the floor.

According to this structure, after closing the stop valve and turning on the switch of the air compressor main body, if the air pressure of the air compressor main body is adjusted to the pressure tank filling pressure by the pressure reducing valve, the air compressor main body Turn off the switch. After that, by opening the stop valve and turning on the switch of the air compressor again, it is possible to fill the pressure tank with air at a stretch,
The air replenishment work can be performed without requiring about 200 times of the injecting operation (pumping operation) as in the conventional case.
