Description

[Detailed Description of the Invention] The present invention relates to a faucet union that can be easily attached to a nipple or the like.

In this type of conventional embedded pipe joint, it is an embedded pipe joint that connects a buried transfer pipe buried inside the foundation construction part and a fluid device installed at a location adjacent to the outside of the finishing layer, and one end thereof. is provided with a threaded portion to be screwed into the end of the buried transfer pipe, and the fitting body is configured to have an appropriate length so that the other end surface matches the finishing layer, and a part of the center hole is provided with a finishing layer. An embedded pipe joint (Utility Model Application Publication No. 49-50828) is characterized by having a hole of different diameter (polygonal hole) that engages with the tip of the installation tool inserted into the center hole from the side. When installing an embedded pipe fitting by screwing the threaded part of the end of the fitting body into the buried transfer pipe buried inside the foundation construction part, insert the polygonal rod of the installation tool into the polygonal hole through the finishing layer side. The pipe fitting was inserted into and engaged with the pipe, the fitting tool was rotated to rotate the joint body, and the pipe joint for embedding was screwed into the pipe.

However, in this embedded pipe fitting, the polygonal hole does not have a protruding edge for the installation tool to abut against.
When the polygonal rod of the installation tool is inserted into the polygonal hole and engaged, the tip of the polygonal rod penetrates the polygonal hole and protrudes beyond one end of the joint body, and in this state, the installation tool is inserted. As the joint body is screwed in by rotating the polygonal rod, the polygonal rod is rotated at an angle, and as a result, torsional force is applied to one end of the joint body, causing a crack. There is a risk of water leaking from some parts. In addition, since the tip of the polygonal rod penetrates the polygonal hole and protrudes beyond one end of the joint body, be sure to grasp the joint body with one hand and press it against the buried transfer pipe to tighten the female screw of the buried transfer pipe. The proximal end of the threaded part at one end of the fitting body is aligned with the inlet, and then the installation tool is grabbed with the other hand and rotated, which is inconvenient as it cannot be installed with one hand. This had the disadvantage that it was extremely troublesome to install because it had to be rotated through the main body.

The present invention was developed in view of the above circumstances, and its purpose is to eliminate the risk of cracks occurring at one end of the main body and cause water leakage, to allow one-handed operation, and to attach the fasteners to the main body. To provide a faucet union whose main body can be easily attached to a nipple or the like by simply inserting a polygonal rod shallowly.

That is, the present invention is a faucet union that connects a nipple, etc. attached to a water pipe located inside a wall, etc., and a faucet disposed outside the wall, etc., in which the nipple is attached to the outer periphery of one end of the main body. A male screw is provided to be screwed into the end of the main body, and between one end hole formed on the inner periphery of one end of the main body and the other end hole formed on the inner periphery of the other end of the main body, the inner diameter of the one end hole is A polygonal hole with a larger diagonal line is formed, and a polygonal rod of a fastener that is inserted into and engaged with the polygonal hole from the faucet side through the other end hole is abutted against one end of the polygonal hole. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention, which relates to a faucet union having a projecting edge and a female screw in a hole at the other end, will now be described with reference to embodiments shown in the accompanying drawings.

The present invention is a faucet union that connects a nipple 12 etc. attached to a water pipe 11 located inside a wall 9 etc. and a faucet 15 disposed outside the wall 9 etc. is provided with a male screw 2 that is screwed into the end of the nipple 12, etc., and is connected to one end hole 4 formed on the inner periphery of one end of the main body 1.
A mortar-shaped hole 3 whose diameter decreases toward the other end of the main body 1 is formed in one end side surface of the main body 1 .

Moreover, a polygonal hole 5 whose diagonal line is larger than the inner diameter of the one-end hole 4 is formed between the one-end hole 4 and the other-end hole 7 formed on the inner periphery of the other end of the main body 1. One end of the square hole 5 is provided with a protruding edge 6 for the polygonal rod 13 of the fastener 14 to fit into the polygon hole 5 from the faucet 15 side through the other end hole 7. Furthermore, the other end hole 7 is provided with a female screw 8.

In the figure, reference numeral 16 denotes a male screw at the base of the faucet 15, which is screwed into the female screw 8 of the other end hole 7 for installation.

Since the present invention has the above-described configuration, the main body 1 is inserted into the hole 10 provided in the wall 9, etc., as shown in FIG. When installing by screwing into the 90 degree nipple 12 etc. attached to the water pipe 11 located inside the body, first, insert the male screw 2 on the outer periphery of one end of the main body 1 slightly into the hole 10 provided in the wall 9 etc. Then, as shown in FIG. 5, the polygonal rod 13 formed at the tip of the fastener 14 as shown as an example in FIG. 4 is inserted into the other end hole 7 of the main body 1 from the faucet 15 side. Then, the polygonal rod 13 is inserted and engaged into the polygonal hole 5, and the tip of the polygonal rod 13 is brought into contact with the abutment protrusion 6 provided at one end of the polygonal hole 5, and the fastener 14 is rotated in this state. When the main body 1 is rotated, the male screw 2 on the outer periphery of one end of the main body 1 is screwed into the nipple 12 at a 90 degree angle.
The main body 1 can be easily attached to the degree nipple 12.

As described above, in the present invention, between the one end hole 4 formed on the inner periphery of one end of the main body 1 and the other end hole 7 formed on the inner periphery of the other end of the main body 1, the inner diameter of the one end hole 4 is A polygon 5 with large diagonal lines is formed, and a fastener 14 is inserted into one end of the polygon hole 5 from the faucet 15 side through the other end hole 7 to fit into the polygon hole 5. Since the abutting protrusion 6 of the square rod 13 is provided, when the male screw 2 provided on the outer periphery of one end of the main body 1 is screwed into the 90 degree nipple 12 etc., it can be inserted into the polygonal hole 5. Fastener 1 that is securely engaged
The tip of the polygonal rod 13 of No. 4 hits the abutting protrusion 6 and does not penetrate the polygonal hole 5 and protrude beyond one end of the main body 1.
During rotation, the polygonal rod 13 is not rotated tilted as in conventional products, and therefore, no cracks are generated at one end of the main body 1. Therefore, the drawback of the conventional product, which has the risk of water leakage due to the formation of cracks, can be solved.Also, during the installation work of the main body 1, as mentioned above, the tip of the polygonal rod 13 has a polygonal shape. Since it does not penetrate through the hole 5 and protrude beyond one end of the main body 1, there is no need to grasp the main body 1 with one hand and grasp the fastener 14 with the other hand. with one hand, and insert the polygonal rod 13 into the polygonal hole 5 of the main body 1.
Installation can be easily done by simply inserting and engaging. Therefore, it is extremely convenient because it can be operated with one hand.

Moreover, the tip of the polygonal bar 13 of the fastener 14 inserted into the main body 1 is inserted into and engaged with the polygonal hole 5 and hits the abutting protrusion 6 provided at one end of the polygonal hole 5. , since the polygonal rod 13 can rotate the main body 1 by simply inserting it into the main body 1 shallowly,
This has the effect of making it easier to attach the nipple 12 etc. attached to the water pipe 11 located inside the wall 9 etc.
