Coupling for a tube body with a bent tubular structure

The present invention relates to a connector for a pipe body having a bent tubular structure in which the outer surface of the bent part bent in a 'L' shape, such as a water outlet of a faucet from which fluid is discharged, has a curved surface. It is dividedly formed so as to cover the outer and inner surfaces of the part at the same time, and each one side is mutually assembled in a sliding coupling method from the bottom to the top. It relates to a tubular connector having a bending tubular structure that can improve the

In general, a faucet is a valve that is installed at the end of a water supply from a water supply to control water, and is used by connecting a water supply hose to the end. Since the faucet has a slippery surface and the water supply hose can be easily separated when the water supply hose is directly connected to the faucet, a hose connector with excellent bonding strength to the faucet is used for connection.

1 is a view showing an example for explaining a hose connector according to the prior art, and is a side cross-sectional view showing a state in which the hose connector and the water supply hose are coupled to the outlet of the faucet.

Referring to Figure 1, the hose connector 2 according to the prior art has a fixed body 2a coupled to the end of the water outlet straight part 1b of the faucet 1, and the fixed body 2a and the lower screw-coupled to the lower part. It includes a cap (2b), and the water supply hose (H) is coupled to the fitting portion (2c) formed on the lower portion of the lower cap (2b), and the lower cap (2b) of the hose connector (2) through the holder (3) and The water supply hose (H) is connected.

The fixed body (2a) is coupled so that the upper part surrounds the water spout straight part (1b), and the water spout straight part (1b) of the faucet (1) by a screw (2f) so that it does not come off from the water spout straight part (1b) is fixed on In addition, a spacer 2d and a rubber packing 2e may be provided inside the fixed body 2a to prevent water passing through the water jet straight part 1b from leaking.

Since the hose connector 2 according to the prior art having such a configuration requires a separate tool such as a screwdriver, etc. as the fixed body 2a is coupled with the water outlet of the faucet 1 through screw coupling, the hose connector 2 ), there was a cumbersome problem of installation and separation. In addition, when the screw coupling between the faucet 1 and the hose connector 2 is easily loosened when vibration occurs due to water pressure, water leakage frequently occurred.

In order to solve this problem, many including Korean Patent Publication No. 10-2010-0107282, Korean Patent No. 10-2130793, Korean Utility Model No. 20-0212005, Korean Utility Model No. 20-0467224, etc. In the prior literature of , a hose connector that can be fixed to the water outlet of the faucet 1 without using a separate screw has been proposed.

However, as most of the hose connectors according to the prior art known so far, including the above-mentioned prior art, have a structure coupled to the straight part of the water outlet extending vertically, when used for a long period of time, the hose connector and The coupling force between the water spouts became loose, and there was a problem that the hose connector was easily separated from the water spout.

The straight portion of the water outlet of the faucet is bent in the direction in which water is discharged from the bent portion, that is, in the same direction as the water pressure direction, and the surface thereof is relatively smooth. For this reason, even if the hose connector is coupled to cover the outer surface of the straight part of the water spout with a strong bonding force, since the direction in which the hose connector separates from the straight part and the water pressure direction of the discharged water are the same, when using for a long period of time, the hose connector should be connected to the straight part of the spout. separation problem arises.
