BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier mounting device for mounting a water purifier on a water tap.

[0002]

2. Description of the Related Art In recent years, household water purifiers have become widespread in order to remove red rust, chalk, smell and the like of tap water, and such water purifiers have been used by being attached to taps of tap water.

[0003] Some household water taps have a thread formed on the outside of the tip so that a foam ring can be screwed into the tap.

Conventionally, to attach a water purifier to such a foam tap, as shown in FIG. 6, a foam ring 22 is screwed onto an external screw 2a formed at the tip of the tap 2, and then, The mounting nut 23 passed through the faucet 2 is moved toward the tip of the faucet, dropped to the outside of the foam ring 22, and the flange 24 formed on the foam ring 22 is pressed against the water purifier main body 4 while being pressed against the flange 24. It is screwed to the water inlet 4a.

[0005] The fittings of such a conventional water purifier, ie,
Since a relatively large water pressure is applied to the foam ring 22 between the foam ring 22 and the mounting nut 23, a rubber packing or a sealing tape is interposed to prevent water leakage, so that the foam ring 22 is attached to the outer screw 2a of the faucet. It is hard to tighten. Further, in order to make rubber packing, seal tape, etc. work effectively, the foam ring 22 is connected to the outer screw 2a.
It is necessary to tighten with sufficient force.

[0006]

However, the conventional foam ring 22 has a substantially cylindrical shape and a relatively small diameter, so that it cannot be easily tightened with bare hands, and the tap 2 is sufficiently and surely secured. In order to perform the tightening, it is necessary to use a tool. In particular, there is a problem that a woman such as a general household cannot reliably and easily attach the water purifier.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a water purifier mounting tool that can easily and reliably mount the water purifier.

[0008]

SUMMARY OF THE INVENTION The present invention comprises a foam ring screwed on a tap of a water supply and a mounting nut for connecting the foam ring screwed on the tap to a water inlet of a water purifier body.

[0011] As shown in FIG.
Is composed of a foam ring 3 screwed into the tap 2 of the tap water, and a mounting nut 5 connecting the screwed foam ring 3 to the water inlet 4 a of the water purifier body 4. An external screw 2a is formed at the tip of the tap 2 of the tap, and the foam ring 3 is screwed into the tap. Foam ring 3
The main body 6 has a substantially cylindrical shape, and a flange 7 is formed radially outward at the lower end of the main body 6 so that the mounting nut 5 is locked to the flange 7 when the mounting nut is dropped. Has become. Inside the foam ring 3,
An inner screw 6a screwed with the outer screw 2a of the faucet is formed. In addition, three protrusions 8a, 8b, 8c protrude from the outer upper end of the main body 6 on the outer periphery thereof at substantially equal intervals. These projections 8a, 8b, 8c
Is formed in a semicircular shape with a certain thickness. As shown in FIGS. 1 and 2, the mounting nut 5 is formed in a substantially ring shape having a radius sufficiently larger than that of the foam ring 3, and has an opening 11 at the center thereof. An inner screw 12 is formed inside the outer peripheral portion 5 a of the mounting nut 5, and is screwed with an outer screw 4 b formed in the water inlet 4 a of the water purifier main body 4. In addition, a number of locking pieces 13 are formed outside the outer peripheral portion 5a to facilitate turning the mounting nut by hand.

Around the opening 11 of the mounting nut 5,
Three grooves 14a, 14b, 14c are formed at positions corresponding to the protrusions 8a, 8b, 8c of the foam ring described above. These grooves 14a, 14b, 14c
The projections 8a, 8b, 8c are formed in substantially semicircular shapes having the same dimensions as those of the projections 8a, 8b, 8c. Fitting recesses 15a, 15b, 15c are formed between the grooves 14a, 14b, 14c to fit and support the protrusions 8a, 8b, 8c of the foam ring, and the grooves 14a, 14b, 14c are formed. The projections 8a, 8b, and 8c of the foam ring that have passed through are placed and supported.

Although not shown, a rubber packing or a seal is interposed between the inner screw 6a of the foam ring 3 and the outer screw 2a of the faucet 2.

Next, the operation of this embodiment will be described.

As shown in FIG. 1, an installation nut 5 is passed through the tap faucet 2 through an opening 11 in advance, and the foam ring 3 is lightly screwed into an external screw 2a formed in the tap with bare hands. I do. Next, the mounting nut 5 is moved to the front end side of the faucet 2 and the projections 8a, 8b, 8 of the foam ring 3 are moved.
c, the grooves 14a, 14b, and 14c are fitted and inserted so that the projections 8a, 8b, and 8c pass through, and the mounting nut 5 is dropped under these. At this time, opening 1
Since the diameter of 1 is larger than the outer circumference of the main body 3a of the foam ring 3 and smaller than the flange 7, the mounting nut 5 engages with the flange 7 and stops. Then, the flange 7
Is slightly rotated to project the protrusions 8a, 8b, 8 of the foam ring 3.
c is lifted up while matching the fitting recesses 15a, 15b, 15c, and the projections 8a, 8b, 8c are lifted up.
The foam ring is supported from below by fitting to 5b and 15c. In this state, as shown by arrow A in FIG.
While pushing and supporting the mounting nut 5 from below toward the faucet 2 of the water supply, the foam ring 3 is tightened and fixed to the faucet 2 by, for example, turning clockwise (direction of arrow B).

In this case, since the mounting nut 5 has a diameter sufficiently larger than the radius of the foam ring 3, the mounting nut 5 can be easily turned with bare hands, and the foam ring 3 is securely and sufficiently tightened. Can be fixed to the faucet. Therefore, water leakage between the tap 2 and the foam ring 3 can be prevented. Moreover, since there is no need to use tools, housewives and the like in ordinary households can be easily attached with bare hands.

After the foam ring 3 is screwed, the mounting nut 5 is dropped on the flange 7 of the foam ring 3 again, and the projections 8a, 8b, 8c and the fitting recesses 15a, 15c are formed.
The connection with b and 15c is removed, and the mounting nut 5 is freely rotatable. Such a mounting nut 5
In the free state, the water inlet 4a of the water purifier body 4 and the lower end of the foam ring are aligned and pressed against each other,
An inner screw 12 of the mounting nut 5 is screwed into an outer screw 4b (see FIG. 1) formed in the water inlet 4a, and the mounting nut 5 is screwed to the water purifier main body 4 as shown in FIG. By screwing the mounting nut 5 to the water purifier main body 4 in this manner, the water suction port 4a and the foam ring 3 are connected to each other.

The present invention is not limited to the above-described embodiments, but can be variously modified without departing from the gist of the present invention.

For example, the fitting recesses 15a, 15b, 15c formed around the opening 11 of the mounting nut 5 are not always necessary, and as shown in FIG. 5, are fitted into the protrusions 8a, 8b, 8c of the foam ring. Grooves 14a, 14b, 14c
