BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet mounting structure, and more particularly, to a mounting structure suitable for a faucet of a water tank for transportation for storing and transporting water, tea or the like.

[0002]

2. Description of the Related Art It is necessary to carry drinking water such as water or tea when enjoying outdoor leisure such as camping or playing sports, but in such a case, it is relatively large. A water tank for transportation is used. Then, drinking water such as water is put into the water tank for transportation through an opening provided on the upper surface side thereof, and the opening is closed by a lid (usually a screw lid), and then provided on the lid. It is common practice to get drinking water out of the tap.

In the conventional water tank for transportation as described above, since the faucet is screwed to the lid, the faucet may be screwed depending on the position of the screw thread on the faucet or the mounting screw portion on the lid side. There was a case that the spout of the squirrel did not face straight down, which made it inconvenient to use the faucet.
Because when you try to screw the faucet to the lid with the mounting screw, you have to firmly stop the drinking water from leaking around the mounting screw.
The faucet is screwed so that it can be completely fixed to the lid, but the faucet when screwed in could have been fixed with its discharge port facing sideways. When the discharge port was facing sideways, it became unclear how much the cup or the like for receiving the drinking water should be positioned with respect to the discharge port, and the drinking water was spilled.

Therefore, the inventor of the present invention can prevent drinking water from leaking from the attachment portion when the faucet is attached to this kind of water tank for transportation, and the faucet is always directed straight down. The present invention has been completed as a result of various studies being conducted on how to make it possible.

[0005]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above-described circumstances, and an object to be solved is to always direct the discharge port of the faucet downward. .

That is, the object of the present invention is to
When attaching the faucet to the lid of the water tank for transportation, it is possible not only to prevent drinking water from leaking from its attachment part, but also to ensure that the outlet of the attached faucet can always be directed straight down. The purpose is to provide a mounting structure that can be performed with a simple structure.

[0007]

In order to solve the above-mentioned problems, the means adopted by the invention according to claim 1 will be described with reference to the reference numerals used in the embodiments. In the water tank for transportation 100 in which the lid 20 is detachably attached to the opening 11 provided in the lid 20 and the faucet 30 is attached to the lid 20, the discharge of the attachment screw portion 34 formed at the attachment end portion of the faucet 30. A first holding edge 31, an O-ring mounting groove 33, and a second holding edge 32 having a diameter larger than that of the first holding edge 31 are sequentially formed on the outlet 38 side, and a second holding edge 32 is formed in the O-ring mounting groove. The O-ring 40, which is slightly larger in diameter than the holding edge 32 and is made of an elastic material, is attached to the lid 20.
The mounting screw portion 3 has a diameter that allows the second holding edge 32 to enter.

And a portion 25 is formed. The attachment structure of the faucet 30 in the water storage tank 100 for transportation ”.

That is, in the mounting structure according to the first aspect of the present invention, the faucet 30 is arranged outside the lid 20 and is screwed to the mounting screw portion 25 thereof.
O-ring 4 attached in O-ring attachment groove 33 of faucet 30
When 0 enters the O-ring storage portion 23 on the lid 20 side, the O-ring storage portion 23 is liquid-tightly sealed, so that drinking water leaks from the mounting screw portion 34 of the faucet 30. Is to prevent. And this O-ring 4
It is possible to further screw the faucet 30 into the lid body 20 while maintaining the relationship between 0 and the O-ring housing portion 23. This is made possible by the mounting screw portion 3
The O-ring storage portion 23 has a depth of at least 1/2 of 4. As a result, in the mounting structure according to the invention of claim 1, the water outlet 38 of the faucet 30 can be directed straight down by twisting the faucet 30.

Further, the means adopted by the invention according to claim 2 is the same as that of the water storage tank for transportation 10 according to claim 1.
Regarding the mounting structure of the faucet 30 in No. 0, "a step portion 24 that restricts the movement of the first holding edge 31 is formed between the O-ring housing portion 23 of the lid body 20 and the mounting screw portion 25. The attachment structure of the faucet 30 in the water storage tank 100 for transportation according to claim 1 is adopted.

That is, in the mounting structure according to the second aspect, the O-ring housing portion 23 and the mounting screw portion 25 of the lid 20 are attached.
The stepped portion 24 that restricts the movement of the first holding edge 31 is formed between the first and the second holding edge 31, and the faucet 30 is screwed into the stepped portion 24 until the first holding edge 31 comes into contact with the stepped portion 24. The location can be easily confirmed, and then the faucet 30 is screwed back so that the water outlet 38 of the faucet 30 can be directed straight down.

[0011]

The operation of the mounting structure according to the invention of each claim constructed as described above will be described below by exemplifying the manner of attaching the faucet 30 to the water storage tank 100 for transportation.

First, in the case where the faucet 30 is not used in the water tank 100 for transportation, the faucet 30 is attached by the attachment screw portion 34 to the lid 20 as shown by the phantom line in FIG. It is screwed inside the portion 25. Of course, at this time, the cock 35 of the faucet 30 is kept in the "stop" state.

When the faucet 30 is screwed to the inside of the mounting screw portion 25 of the lid 20, the mounting screw portion 25 of the lid 20 is attached.
Since the chamfered portion 26 is formed on the inner end side of the faucet 30
The first holding edge 31 on the side comes into liquid-tight contact with the chamfered portion 26. Therefore, even if the drinking water undulates around the faucet 30, the drinking water does not leak out from the side of the mounting screw 25 of the lid 20.

As described above, the lid body 20 having the faucet 30 attached to the inside thereof has the threaded portion 12 formed on the outer periphery of the opening 11 of the tank body 10 as shown in FIG.
Is to be screwed on. As shown in FIG. 7, for example, as shown in FIG. 7, a packing 22 that comes into contact with the end surface of the opening 11 on the tank body 10 side is attached to the inside of the lid body 20. Therefore, as shown in FIG. As a result of being attached to the opening 11 of the tank body 10 in a liquid-tight manner, it is natural that the drinking water does not leak from the mounting screw 21 of the lid 20.

As described above, when the opening 11 of the tank body 10 is closed by the lid 20 having the faucet 30 attached to the inside thereof, the faucet 30 of the water tank 100 for transportation is shown in FIGS. 1 to 3. Not only can the transportation water storage tank 100 be transported without hindrance without protruding outward, but also something can be placed on the upper surface of the transportation water storage tank 100.

Now, using the faucet 30, the tank body 1
When the drinking water in 0 is to be taken out, the lid body 20 is removed from the opening 11 of the tank body 10 as shown in FIG. 4, and is attached to the inside until then as shown in FIG. The faucet 30 that was there is removed and attached to the outside of the lid 20. At this time, the mounting screw portion 34 on the side of the faucet 30 is screwed onto the mounting screw portion 25 of the lid 20 from the outside as shown by the solid line in FIG. 7 and FIG. When the O-ring 40 is completely inserted into the O-ring storage portion 23 on the lid 20 side, the O-ring 40 firmly fitted in the O-ring attachment groove 33 of the faucet 30 is shown by the solid line in FIG. As shown, the O-ring storage portion 23 on the lid 20 side is elastically deformed.
It is in liquid-tight contact with the inner surface of the. In this state, the first holding edge 31 on the side of the faucet 30 has the step portion 2 on the side of the lid 20.
4 does not come into contact with the O-ring 40 at the end, and there is a gap in the front portion (on the right side in FIG. 8) of the O-ring 40 that allows the O-ring 40 to advance. Exists in.

Further, at this time, the second holding edge 32 is formed so as to have a diameter larger than that of the first holding edge 31, and has a size such that the second holding edge 32 can enter the O-ring accommodating portion 23 on the lid 20 side. Therefore, while the holding of the O-ring 40 by the first holding edge 31 and the second holding edge 32 is ensured, the pushing of the O-ring 40 into the O-ring housing 23 is maintained while maintaining its liquid-tight state. It is something that is surely done. That is, the O-ring 40 is surely held by the second holding edge 32 substantially entirely on the outer side surface thereof, and the first holding edge 31 has a smaller diameter than the second holding edge 32. The O-ring 40 can be sufficiently elastically deformed in the ring housing portion 23.

Further, in this embodiment, the O-ring 40 is used.
The O-ring 40 has a substantially circular cross-sectional shape.
When it is pushed in, it freely rotates in the O-ring attachment groove 33 and moves while maintaining a liquid-tight contact state in the O-ring housing 23. This makes O
The friction of the ring 40 in the O-ring housing 23 is minimized, and the faucet 30 can be rotated easily.

As described above, the opening 11 of the tank body 10 is closed again by the lid 20 having the faucet 30 attached to the outside, and in order to make the drinking water in the tank body 10 easy to use, As shown in FIG. 6, the water storage tank 100 for transportation is stood and placed on the table. In this case, there is no problem if the discharge port 38 of the faucet 30 is already directed straight down, but if not, the following is performed.

That is, the water tank 100 for transportation is shown in FIG.
When the state shown in FIG.
If 8 is in a direction other than straight down, the whole faucet 30 is gripped and further screwed. Faucet 3
As described above, the first holding edge 31 of 0 and the O-ring 40 still have a sufficient gap in front of the screwing side, and this screwing can be sufficiently performed. If this is the case before the screwing in, the outlet 38 of the faucet 30
Is facing straight up, add 18
If it is rotated by 0 ° and screwed in, the discharge port 38 will face straight down as shown in FIG. 6, so the depth of the O-ring storage portion 23 is set to allow this 180 ° screwing. It suffices to have at least the 1/2 pitch of the mounting screw portion 34. However, in the following embodiments, the depth of the O-ring storage portion 23 is set to 1 pitch or more of the mounting screw portion 34 in consideration of not only screwing but also screwing backward to turn the discharge port 38 straight down. There is something.

As described above, even if the faucet 30 is further screwed in, the O-ring 40 is maintained in a liquid-tight contact with the inner surface of the O-ring housing portion 23. It goes without saying that no drinking water will leak out. Moreover, since it is not necessary for the O-ring 40 to be further elastically deformed at the time of screwing in, it is not necessary to apply much force when screwing in the faucet 30.

If the discharge port 38 of the faucet 30 faces straight down,
The vent plug 13 on the tank body 10 side is removed as shown in FIG. 6, and the cock 35 is rotated so that the discharge port 38 communicates with the inside of the tank body 10. The drinking water inside can be removed. In this case, since the discharge port 38 faces straight down, drinking water can be completely received without spilling the drinking water by simply inserting a cup or the like under the discharge port 38.

Of course, if the lid body 20 is attached to the empty tank body 10 so that the faucet 30 is located inside the tank body 10, as shown in FIG. There is nothing to do as described above.

Further, if the mounting structure according to the present invention that exhibits the above-mentioned effects is adopted, the tank body 10 and the lid body 2
0 and the faucet 30 are molded from a synthetic resin, the mounting screw portions 25 and 34 do not need to be formed at such strict positions, and therefore the water tank 100 for transportation is provided.
The whole manufacturing is easier.

Particularly, according to the mounting structure of claim 2,
Since the step portion 24 that restricts the movement of the first holding edge 31 is formed between the O-ring housing portion 23 of the lid 20 and the mounting screw portion 25, the step portion 24 has the first holding edge 31. By screwing the faucet 30 until it comes into contact, the maximum screwed-in portion can be easily confirmed. After that, by screwing the faucet 30 back, the spout 3 of the faucet 30 can be confirmed.
8 is directed straight down.
