Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet plier, and more particularly to a faucet plier having a function of tightening a refill socket for use when the length of a water supply pipe is insufficient at a construction site.

[0002]

2. Description of the Related Art In general, pliers are often used for installing a water supply faucet, repairing and checking. Then, in connecting the water tap, when connecting a water tap (hereinafter referred to as a tap) to a terminal of a steel pipe for water pipe (hereinafter referred to as a steel pipe), as shown in FIG. The elbow 4 is connected to the steel pipe and the direction is changed.
, A faucet 2 is connected from the front side of the wall surface 1. FIGS. 7 and 8 are explanatory diagrams showing examples of a faucet connection state in which the wall surface 1 is cut off.

[0003] The thickness of the wall surface 1 varies at construction sites and is not constant. Therefore, there are cases where the connection cannot be made short only with the steel pipe 3 for penetrating the wall surface (for example, the case of FIG. 8). In this case, an off-the-shelf refill socket 5 is used as shown in FIG. This uses a refill socket 5 rather than preparing a slightly longer steel pipe for penetrating the wall, cutting it according to the thickness of the wall at the site, cutting the cut end and screwing it to an elbow. This is because the work is easier and requires less time.

As shown in FIG. 2 or FIG. 3, the extension socket 5 has a stepped cylindrical shape, and a male screw 5a is provided outside the thin cylinder on the steel pipe side and inside the thick cylinder on the faucet 2 side. Is provided with a female screw 5b. The male screw 5a on the steel pipe side is connected to a female screw 3a provided inside the steel pipe end, and the female screw 5b on the faucet side is connected to a male screw (not shown) at the entrance of the faucet 2.

[0005] A steel pipe 3 for penetrating the wall and a refill socket 5
Must be turned in the direction in which the refill socket 5 is screwed. For this purpose, the portion of the water passage 5c of the extension socket 5 has a hexagonal cross section. Conventionally, in order to rotate the extension socket 5,
Use a special L-shaped wrench and connect one end to the water passage 5c.
Was inserted and turned.

On the other hand, a conventional faucet plier has a new function so that the replacement of the packing of the water stop valve (Kelep) is troublesome, and the Kellep can be easily taken out without requiring a special part. The added pliers with kerep removal function are registered as utility model No. 3035628
No. has been proposed.

[0007]

There is no conventional pliers of this type, including the above-mentioned pliers with a kerep removing function, which also has a function of tightening a refill socket. Therefore, when installing the faucet,
When the additional socket is expected to be used, there is a problem that a special tool such as a hexagonal L-shaped wrench must be prepared in addition to the faucet pliers. An object of the present invention is to solve the above-mentioned problems, and to provide a water tap plier having a function of screwing a refill socket into a steel pipe without requiring a special tool.

[0008]

In order to solve the above-mentioned problems, a faucet plier according to the present invention is inserted between a water supply pipe and a water tap to be connected to each other near the tip of at least one handle. In this configuration, a refill socket for screw connection is provided with a rectangular column-shaped portion that can be rotated about an axis.

Specifically, the faucet pliers include a hole provided at the tip of at least one handle toward the center of the handle, an outer diameter smaller than the inner diameter of the hole, and an inner diameter of the water stop valve. A vinyl tube inserted into the hole having a size suitable for picking up the water stop valve by press-fitting the lifting rod from the outside, and having an outer diameter slightly larger than the inner diameter of the hole, and A faucet plier, comprising: a metal ring that is smaller than the outer diameter of the vinyl tube and larger than the inner diameter of the vinyl tube and that is press-fitted to the handle tip side of the hole; A hexagonal column-shaped portion that can be fitted and fitted into a hole provided along the axis of the refill socket may be provided at the center of the handle subsequent to the portion containing the provided hole.

[0010] Alternatively, the faucet plier is, specifically, a faucet plier provided with a driver portion having the same function as the tip portion of an independent driver at the tip of at least one handle. Subsequently, a hexagonal column-shaped portion that can be fitted and fitted in a hole provided along the axis of the refill socket may be provided on the central portion of the handle.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view (plan view) showing an embodiment of the present invention. The inside of the larger circle surrounded by the dotted line in the figure is an enlarged view of the smaller circle surrounded by the dotted line in FIG. In FIG. 1, reference numerals 11 and 12 indicate a pair of handles of the faucet pliers of the present invention. 11a and 12a are tips of the handles 11, 12 respectively.

Reference numeral 10 denotes a hexagonal column-shaped portion provided near the center of the handle, following the tip 11a of the handle 11 having a function of removing kerep. In the embodiment shown in FIGS. 1 to 5, the kelep removing function is such that the elastic tube 3 and the vinyl tube 3 come out to the outside in a hole provided in the center of the handle at the tip end 11a. Stop ring 4 made of metal such as brass to prevent
It is configured by inserting.

FIGS. 2 to 4 are explanatory diagrams showing the use of the pliers of the present invention when the steel pipe 3 for penetrating the wall is short and the faucet cannot be connected as shown in FIG. FIG. 2 is an explanatory diagram showing a state before cutting the wall surface 1 before screwing the male screw 5a of the refill socket 5 into the female screw 3a provided at one end of the steel pipe 3. FIG. 3 is an explanatory view showing the state of FIG. 2 in a perspective view.

The connection between the refill socket 5 and the steel pipe 3 may be made by turning the socket 5 while screwing the male screw 5a of the socket 5 and the female screw 3a of the steel pipe 3 at their ends. FIG. 4 shows the external thread 5a of the extension socket 5.
FIG. 4 is an explanatory view showing a situation in which is screwed into a female screw 3 a of a steel pipe 3.

A portion of the water passage 5c of the extension socket 5 is formed as a through-hole having a hexagonal cross section. When rotating the extension socket 5, the handles 11 and 12 of the pliers shown in FIG. 1 are widely opened as shown in FIG. 4, and the hexagonal columnar portions 10 of the handle 11 are fitted into the water passages 5c so that the handle 11 is pivoted. If it is turned, a large torque is transmitted to the socket 5.

In addition to the embodiments described above, various modifications are conceivable, all of which are included in the present invention. In the case of the faucet pliers of FIG. 1, the tip 11 a of one handle 11 is a portion having a kerep removing function, and one hexagonal column-shaped portion 10 is provided subsequently thereto. The tip 12a of the other handle 12 has a function of a driver which is almost always used when using the faucet pliers.

However, the dimensions of the extension sockets are not limited to one, and there are some differences in the size of the hexagonal cross section of the water passage.
As shown in FIG. 5, hexagonal columnar portions 20 and 30 may be provided in two stages. In this case, the thin hexagonal columnar portion 20 is made closer to the tip, followed by the thick hexagonal columnar portion 30.

Further, in order for the faucet pliers to have a function of rotating the refill socket 5, it is sufficient that the faucet pliers have the above-mentioned hexagonal columnar portion. Therefore, as shown in FIG. 6, the tip portion 21a of one handle 21 has only a portion having a kerep removing function, and a portion having a driver function of the tip portion 22a of the other handle 22 has a hexagonal column shape in the center direction of the handle. A unit 40 may be provided. Note that a hexagonal columnar portion may be provided in two stages instead of the hexagonal columnar portion 40 in FIG. Although not shown, each of the two handles may be provided with a hexagonal column-shaped portion having a different size for each one.

[0019]

As described above in detail, the faucet pliers of the present invention rotate the refill socket inserted between the steel pipe and the faucet around the axis near the tip of at least one handle of the pliers. By providing the rectangular column-shaped portion which can be used, there is an effect that the pliers can be added to the steel pipe and the socket can be screwed into the steel pipe without requiring any special tool. Therefore, it is not necessary to carry a special L-wrench separately at the construction site as in the past, and since the handle is opened and the socket is turned, a larger torque can be obtained than with the special L-wrench. It can be securely connected with a simple tightening force.
