Description

Air pole for tent {AIR POLE FOR TENT}

The present invention relates to an air pole for a tent, which greatly improves the exhaust speed by forming an exhaust hole in the air valve, thereby exposing the exhaust hole to the outside by rotating the air valve in the direction of disassembly.

Fire hoses can largely include jacketed fire hoses and round-maintaining fire hoses.

A jacketed fire hose may have a flat shape when stored (before fire extinguishing water is used) and a circular shape when used (when filled with fire extinguishing water).

A round-retaining fire hose may have a circular cross-section both during storage and use.

As an air pole using a double-jacketed fire hose, a known one is disclosed in, for example, a patent document (Korean Patent No. 10-2182585).

The jacketed fire hose is not only excellent for maintaining the original shape of the tent as it can pressurize at a higher pressure than a regular air pole. Durability can be significantly improved by using a jacketed fire hose coated with polyurethane on the inside and a secondary finish with fabric on the outside.

In the air pole for tents in the patent document, circular couplings may be installed on both ends of the jacket fire hose, and a stopper may be fastened to block the ends of the circular couplings.

In addition, an air valve is installed on one of the circular couplings at both ends, and air can be injected or exhausted into the interior through the air valve.

However, since the air valve is installed in the circular coupling, the entire air pole must be replaced when replacing the air valve. This is because the jacketed fire hose is made of an integrated tube that is expanded and fixed to the inner circumferential surface of the circular coupling.

In addition, the air can be quickly exhausted by opening the fastening hole of the stopper with a tool, but not only is the tool absolutely necessary, but the air exhaust hole suddenly widens, which can cause danger, such as blowing off the stopper due to great pressure.

Korean Patent No. 10-2182585

In order to solve the above-described problem, the purpose of the present invention is to provide an air pole for a tent that can quickly exhaust air from the high-pressure air pole without completely disassembling the coupling portion by simple operation of the air valve.

In order to achieve the above-described object, the air pole for a tent of the present invention includes a jacket hose, first and second coupling parts installed at both ends of the jacket hose, and one of the first and second coupling parts. It includes an air valve installed, wherein the air valve includes a male threaded valve body fastened to a female threaded hole formed in one of the first and second coupling parts, extending outward from the male threaded valve body, and connected to the female threaded hole. It may include a valve body that is caught, a check valve installed inside the valve body, a valve cover that is fastened to the valve body while surrounding the check valve, and an exhaust hole formed in the diametric direction in the male threaded valve body. .

In the tent air pole of the present invention, the first and second coupling parts include first and second couplings installed at both ends of the jacket hose, and first couplings fastened to ends of the first and second couplings. ,2 It includes a stopper, and the air valve can be fastened to the female threaded hole formed in any one of the first and second stoppers.

According to the tent air pole of the present invention, the following effects are achieved.

By forming an exhaust hole in the male threaded valve body of the air valve, the air from the air pole can be quickly exhausted without completely disassembling the air valve from the coupling part.

If an air valve is installed on the stopper fastened to the end of the coupling fixed to both ends of the hose, when replacing the air valve, just remove the stopper and replace it with a stopper with a new air valve installed. Therefore, it is excellent in terms of maintenance and economics because there is no need to replace the entire air pole as before.

Of course, since the air valve is removable, only the air valve can be replaced, and in this case, the stopper can be assembled without being separated.
