Hose-coupling device for faucet {A HOSE-COUPLING DEVICE FOR BIB COCK}

The present invention relates to a hose-coupling device for a faucet, and more particularly to a hose-coupling device for a faucet to be used by connecting the hose to the faucet installed to protrude from the wall of the building.

In general, a washing machine, a water sprayer, and the like are used by connecting an end of a hose to a faucet through a coupling, and is usually operated while the valve of the faucet is opened. This results in significant pressure on the faucet and hose in the absence of tap water discharge.

Therefore, in order to prevent the end of the hose which is subjected to high hydraulic pressure from the faucet, the conventional coupling is a rubber packing is disposed therein, it is fixed to the end of the faucet through a plurality of tightening screws. However, such a conventional coupling has an inconvenience in installation work that requires tightening the tightening screw through a tool, and has a disadvantage in that a leak occurs or is easily separated as the tightening force of the tightening screw is weakened.

Coupling for faucet connection to solve this disadvantage is disclosed in Utility Model Registration No. 20-0342609 registered on February 09, 2004. Coupling for faucet connection of Utility Model Registration No. 20-0342609 has a hole (12) to one side, as shown in Figs. 1 and 2, a screw portion 14 is formed on the lower periphery and the fixture is assembled outside the discharge pipe of the faucet 10, and the connector 20 is inserted into the fixture 10, the inlet groove 22 is formed in the discharge pipe lower portion of the faucet to the upper side is formed and the fitting portion 20 is formed with a fitting portion 24 for assembling a hose in the lower portion And, the upper portion is provided with a screw portion 32 is fastened to the screw portion 14 of the fastener 10 and the lower surface is characterized by consisting of a fastener (30) formed with a step (34). Therefore, the coupling can be easily and quickly installed or dismantled in the faucet without a separate tool, and the simple structure has the advantages of good productivity and reduced manufacturing cost.

However, the conventional faucet connection coupling has an advantage that it can be easily mounted on the discharge pipe of the faucet through a screw coupling method, while the structure that can securely hold the end of the hose connected to the coupling is not provided. There is a disadvantage that the hose end is easily separated from the fitting portion 24 of the connector 30 during use.

The present invention is to solve this problem; It is an object of the present invention to provide a faucet hose coupling device that can be easily and reliably mounted on a faucet as well as the end of the hose is mounted more reliably so that it cannot be separated even if high water pressure is applied.

The present invention for achieving this object is; A hose-coupling device for a faucet for connecting a flexible hose to an outlet end of the faucet;

The faucet hose coupling device; A cap-shaped fixing member having a female screw formed on the upper inner wall thereof, the insertion hole being perforated to surround the outlet end of the faucet, and the open inner bottom wall of the faucet formed therein; A handle portion having an outward flange shape is provided at the center, and the inlet portion protrudes to be inserted into the outlet end of the faucet and is formed to surround the inlet portion, and is screwed on the bottom of the fixing member. The first male screw portion is coupled, the lower side of the handle portion is in communication with the inlet and the outlet of the hose protrudingly extended so that the end of the hose can be connected to the connection member formed of a second male screw portion formed to surround the outlet Wow; A lower end portion accommodated inside the first male screw portion of the connection member, and a rubber packing in the form of a tube surrounding the outer circumference of the outlet end of the faucet; It is arranged to surround the upper end of the rubber packing, and made of a ring shape formed with a branch groove at regular intervals along the wall surface as the inner diameter decreases as the screw connection between the connecting member first male screw portion and the fixing member female screw proceeds. A first pressing ring for closely contacting an upper end of a rubber packing to an outer circumference of the outlet end of the faucet; A fastening member having a female thread formed on an upper inner wall of the upper end wall to be inserted into an outlet of the connecting member to penetrate an end portion of the hose and to be coupled to the second male screw portion of the connecting member by a screw coupling method; It is arranged to surround the end of the hose fitted in the outlet of the connecting member is formed in the form of a ring formed with a branch groove at regular intervals along the wall as the screw coupling between the connecting member second male screw portion and the tightening member female screw proceeds. A second pressing ring which closes the end of the hose to the outlet of the connecting member while the inner diameter thereof is reduced; It is characterized by including.

In addition, the hose-coupling device for a faucet according to the present invention; The upper end of the first pressing ring is in contact with the upper inner wall of the female screw of the fixing member is made of a tapered wall surface of the inner diameter gradually decreases toward the upper side so that the inner diameter gradually decreases; The lower end of the second pressing ring is in contact with the lower inner wall of the female screw of the tightening member, characterized in that the tapered wall surface is gradually reduced toward the lower side so that the inner diameter gradually decreases.

According to the hose-coupling device for a faucet according to the present invention; Fix the connecting member where the rubber packing and the first pressing ring are placed by hand without any tools and fix it to the fixing member fitted to the outlet end of the faucet by hand, and then insert the hose end into the outlet of the connecting member and place the second pressing ring. In one state, tighten the tightening member by hand. Accordingly, there is an advantage that the hose-coupling device for the faucet can be mounted firmly and easily at the outlet end of the faucet without using a separate tool.

In addition, according to the hose-coupling device for a faucet according to the present invention; At the outlet end of the faucet there is an advantage that the inlet of the connection member is firmly linked while leaking by the rubber packing.

In addition, according to the hose-coupling device for a faucet according to the present invention; At the outlet of the connecting member, the end of the hose is pressed by a strong force by the second pressure ring, so that the valve of the faucet is opened and a considerable hydraulic pressure is applied to the hose.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 3 to 5 show the configuration of the hose-coupling device for a faucet according to the present invention, Figures 6 to 9 is a process of using the hose-coupling device for a faucet according to the present invention Will be shown sequentially.
