Description

Fire hose for preventing twisting of the connection of the hydrant valve and the pipe window nozzle using the imported connector and the plugging connector

The present invention relates to a fire hose for preventing kinking of a hydrant valve and a pipe window nozzle connection using an import connector and a plug connector, and more particularly, an import connector coupled to the hydrant connector and a plug connector coupled to the pipe window nozzle through free rotation. It relates to a fire hose for preventing twisting of a hydrant valve and a pipe nozzle connection using an import connector and a plug connector to prevent twisting of the fire hose by preventing the hose from being twisted or untwisting automatically or manually even if it is twisted.

A conventional fire hose consists of an import connector, a borrowing connector, and a fire hose connected between the import connector and the borrowing connector, as in Patent Registration No. 1331061 (registered on November 13, 2013).

The import connector is fastened to the hydrant valve, and the outlet connector is fastened to a pipe window or nozzle.

The intake connector consists of an import port coupled to one end of the fire hose, and an import coupling disposed at the tip of the import port, and the import coupling is rotatably connected to the inlet port by a C-ring.

In addition, a female screw is formed on the inner surface of the import coupling, the female screw is fastened with the male screw of the hydrant valve, and a rubber packing is installed at the rear end of the import port. Therefore, the tip of the hydrant valve is pressed in contact with the rubber packing to form a seal.

The plug-in connector is composed of an inlet coupled to the other end of the fire hose and a male screw formed on the outer circumferential surface of the inlet, and the male screw is fastened to the pipe window or the female screw of the nozzle, and the tip of the inlet is the inlet of the pipe window or the female screw side of the nozzle. Form a seal by pressing it in contact with the rubber packing mounted on the

This conventional fire hose is easy to assemble or disassemble when the female screw of the import connector is inserted into the male screw of the fire hydrant valve and rotates the import coupling. It should automatically prevent kinking of the fire hose by rotating it relative to the imported coupling through the buoy.

However, if the tip of the male screw applies a great pressure to the packing towards the rear end of the inlet port, the hydrant valve and the inlet port remain in a fixed state that does not rotate. do.

In the case of not being able to automatically untwist these fire hoses, if the length of the first fire hose and the second fire hose must be increased depending on the fire area, the same occurs when the first plug-in connector and the second import connector are connected to each other. .

That is, when the first plug-in connector of the first fire hose and the second import connector of the second fire hose are fastened to each other, the tip of the first plug-in connector comes into contact with the second packing of the second import connector due to the large pressure being waterproofed. .

Therefore, when the first fire hose or the second fire hose is in a twisted state, the second import connector does not rotate and thus does not automatically unscrew.

In order to prevent this drawback, the import connector for preventing twisting of the fire hose includes: an import coupling in which a female screw is formed on the inner circumferential surface of the rear side; Inlet port to which the other end of the hose is fixed in front; an import intervening portion interposed between the outer peripheral groove formed on the outer peripheral surface of the import port and the inner peripheral groove formed on the inner peripheral surface of the import coupling, allowing a relative rotational movement between the import port and the import coupling; A packing seat portion protruding inwardly from the inner circumferential surface of the import coupling between the female screw and the inner circumferential groove; includes, but the intervening portion is implemented as a ball or a snap ring.

However, since the imported intervening part made of a ball or a step ring prevents kinking while a plurality of balls are inserted in the circumferential direction, in the case of a ball, it takes a lot of time to insert the ball after forming a hole in the outer diameter, resulting in lower productivity. In addition to the drawbacks, the hole through which the ball was supplied must be closed, so that external structures such as screws or rings appear and cause deterioration of product quality.

[Document 1] Patent Registration No. 1331061 (Registered on November 13, 2013) [Document 2] Utility Model Registration No. 0414982 (Registered on April 20, 2006) [Document 3] Patent Registration No. 1331060 (Registered on November 13, 2013) [Document 4] Patent Registration No. 1998146 (registered on 07. 03. 2019)

Therefore, it has been devised to solve these conventional drawbacks, and the solution of the present invention is to fire a fire hydrant or a fire hose regardless of whether a fire hose is used or not at the part connected through a coupling when fastening in connection with a pipe window nozzle. An object of the present invention is to enable the prevention of kinking by preventing the kinking of the hose and allowing the kinked state to be easily or automatically released.

Another problem of the present invention is to wrap the guide protrusion of the inlet and the inlet, and the rotation guide member is screwed or pinned to the coupling so that the inlet and the inlet to which the fire hose is connected are rotated freely, and the fire hose The purpose is to make connection and disconnection convenient and quick.

The present invention includes a fire hydrant valve and an import connector coupled to a connection groove, an import port to which a fire hose is connected, a rotation guide member fixed to the import coupling, and an import coupling fixed to the hydrant valve, allowing the inlet to rotate freely. do; The plug-in connector connected to the pipe window nozzle is coupled to the connecting groove and includes an inlet to which a fire hose is connected; but;
The inlet and outlet have a packing groove in which the packing is fixed to the outer diameter is formed, and after forming a hose fixing part to which the fire hose is fixed, a guide protrusion that is not caught by the rotation guide member and is not separated in the central part of the outer diameter protrudes and rotates freely being installed to do so;
The import connector and the plug-in connector form a fixing hole in the rotation guide member that is coupled to the fastening space of the import coupling and the plug-in coupling, and a hole in the import coupling and the plug coupling that matches the fixing hole formed in the rotation guide member to form,
The hole is formed from the outer diameter of the import coupling and the plug-in coupling to the part passing the fastening space, and the fixing pin is fixed through the hole of the import coupling and the plug-in coupling and the fixing hole of the rotation guide member. it is characterized by
