Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge device that is connected to the outlet of a faucet and is swingable relative to the faucet.

As this type of dispensing device, the one shown in FIG. 4 and disclosed in Japanese Utility Model Application No. 57-133670 is conventionally known.

To explain the example shown in Fig. 4, a heat insulating cap 5 made of synthetic resin is inserted into the cap attachment part 2 provided at the tip of the main body 1 of the discharge device A connected to the outlet 10 of the faucet B, and the cap A set screw 11 screwed into the main body 1 through the circumferential wall 5 also prevents the cap 5 from coming off and rotating.

Therefore, with this type of cap, it is necessary to drill a hole for the set screw separately from the hole for discharging water, which of course weakens the strength of the cap, and the outside diameter of the set screw is small, making it difficult for the set screw and cap to separate. The contact area of the cap is small, and when rotational force is applied to the cap, the force per unit area applied to the part of the cap that contacts the set screw is large, so there is a risk of cracking the cap.

The technical problem to be solved by the present invention is to allow the cap to function as both a water discharge hole and a stopper hole without having to take the trouble to provide a hole for the stopper to prevent the cap from coming off and rotating.

The technical means taken by the present invention to achieve the above-mentioned technical problem is to form the discharge device into a tubular shape, connect the base end to the outlet of the faucet, and attach a cap attachment part to the outer peripheral surface of the distal end. and a main body having a first opening communicating between the inside and the outside on the lower surface of the cap mounting portion, and a male thread provided in the first opening, and a cap mounting portion of the main body formed into a cylindrical shape with a bottom. a synthetic resin cap having a second opening in a portion corresponding to the first opening; a cylindrical shape having a male thread at one end; The cap is inserted through the opening and screwed onto the female thread of the first opening, and the upper surface of the flange provided on the outer periphery of the middle portion is configured with a guide tube that abuts the lower surface of the periphery of the second opening of the cap. Insert the cap through the second opening, screw the male screw into the female screw in the second opening of the main body, and clamp the cap between the flange on the outer periphery of the guide cylinder and the lower surface of the periphery of the first opening of the main body. This prevents it from coming off and rotating.

Since the present invention has the above configuration, it has the following advantages.

Since the outer diameter of the guide tube is larger than that of conventional fasteners, it will not break or deform due to rotational force applied to the cap, and the contact area between the guide tube and the cap will be wider, preventing the cap from wobbling relative to the main body. do not have.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG. 1, an outlet 10 is attached to the upper surface of a hot water mixing faucet B, and in the figure, 1 is the main body of a discharge device A, the cross-sectional shape of which is approximately horizontal. An inlet 12 formed in an oval tube shape and protruding downward at the base end.
A rotating shaft cylinder 13 is connected to the inlet 12.

Further, the main body 1 has a distal end portion closed, and a cap attachment portion 2 is provided on the outer peripheral surface of the distal end portion, and a cap attachment portion 2 is covered with a cap 5 made of synthetic resin such as ABS resin.

The cap attachment part 2 forms a stepped part 14 with respect to the other part of the main body 1 that is continuous to the base side of the part, and has a first opening 3 in the lower surface that communicates the inside of the main body 1 with the outside.

The first opening 3 is provided with a female thread 4 on its opening circumferential surface, and a guide tube 7, which will be described later, is screwed into the first opening 3.

The cap 5 is made of synthetic resin with heat insulation properties and is attached to the main body 1.
It is formed into a bottomed cylindrical shape having an inner peripheral surface shape roughly corresponding to the outer peripheral surface shape of the cap mounting portion 2 of the main body 1, and a portion corresponding to the first opening 3 of the main body 1 when inserted into the cap mounting portion 2 of the main body 1. A second opening 6 is opened in .

The second opening 6 is formed to have a slightly larger diameter than the first opening 3 of the main body 1.

The guide tube 7 is formed into a cylindrical shape having an outer diameter that is the same as the diameter of the first opening 3 at least in its upper part, and has a male thread 8 on its outer peripheral surface that corresponds to the female thread 4 of the first opening 3 at the upper end. A packing 15 is fitted adjacent to the lower end of the male screw 8.

Further, the guide tube 7 is provided with a flange portion 9 at a midway point in the axial direction of the outer peripheral surface, and a male screw 16 for attaching a cap nut at the lower end thereof, and a net member 17 is hooked to the male screw for attaching the cap nut 16. A cap nut 18 is screwed on, and a rectifying member 19 is fitted inside.

Then, the guide tube 7 is inserted through the second opening 6 of the cap 5 and the male screw 8 at the upper end is inserted into the first opening of the main body 1.
It is screwed into the female screw 4 of the opening 3, and the upper surface of the flange 9 is brought into contact with the lower surface of the peripheral edge of the second opening 6 of the cap 5, so that the cap 5 is clamped together with the lower surface of the main body 1.

At this time, the gasket 15 provided adjacent to the lower end of the male thread 8 of the guide tube 7 tightly adheres to the inner circumferential surface of the first opening 3 of the main body 1 to prevent leakage from this portion.

Thus, the cap 5 is connected to the main body 1 by the guide tube 7.
Prevents it from falling off and rotating.

In such a dispensing device A, a rotary shaft cylinder 13 connected to an inlet 12 at the base end of the main body 1 is inserted into an outlet 10 on the top surface of a hot water mixing faucet B, and a flange 20 provided on the outer circumferential surface of the midway part of the rotary shaft cylinder 13 is inserted. is latched to a latching claw piece 22 of a cover metal fitting 21 screwed onto the outer periphery of the outlet 10.

Therefore, the discharge device A is attached to the hot water mixing faucet B so as to be swingable.

And, the swing of the above-mentioned discharge device A is cap 5.
By pinching and operating the cap, the heat insulating properties of the cap 5 allow the cap to be easily operated without danger even when hot water is being discharged.

In this embodiment, the tip of the main body is closed, so if only the gap between the inner circumferential surface of the first opening of the main body and the outer circumferential surface of the guide cylinder is sealed, there is no risk of leakage. There is also the effect that only one piece is enough, and the number of packskin is small.
