[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for freely controlling an antifreeze faucet.

[0002]

2. Description of the Related Art Conventionally, antifreeze water faucets have been required to be able to freely change the direction of an inlet and an outlet for convenience of construction because a valve box portion is buried underground. As shown in Japanese Patent Publication No. 49-7972, a square groove is formed in an outer peripheral portion below a valve box having an outflow port, and is engaged with a square ring which is fitted into the square groove or a part of which is cut off. The cap nut is screwed in such a manner that the lower end of the valve box having an outlet is located at the upper end of the valve box having an inlet through a packing, with a male screw formed on the outer peripheral portion of the upper end of the curved pipe on the inflow side, When the square ring and the step of the valve box are fastened and fixed to the bent pipe by the cap nut, if you want to freely change the direction of the inlet and outlet, loosen the cap nut and rotate the inlet and outlet. And select an appropriate position and tighten the cap nut again The law has been generally performed. However, in the above structure, it takes time to loosen or tighten the cap nut, and furthermore, the square ring must be inserted from the lower end of the valve box and pushed up the cap nut to fit into the square groove. There was a disadvantage that the span from the groove to the outlet had to be lengthened.

[0003]

[Problems to be Solved by the Invention] Therefore, in the present invention, the direction of the inlet and the outlet can be freely selected without loosening or tightening the cap nut, and from the square groove of the valve box to the outlet. It is an object of the present invention to provide an antifreeze faucet freely adjustable device that can shorten the span of the water faucet.

[0004]

According to the present invention, a square ring insertion opening is provided on the side surface of a cap nut, and a square ring is fitted into a square groove formed on an outer peripheral portion of one valve box from the square ring insertion opening.
The square ring is fastened with a cap nut and the other valve box, and the tightening force does not act on one valve box.

[0005]

[Action] Therefore, the direction of the inlet and outlet can be freely changed while the cap nut is tightened,
Further, since the square ring can be inserted without pushing up the cap nut, the valve box can be much shorter.

[0006]

FIG. 1 shows an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a valve box, which is an inlet-side valve box 3 having an inlet 11 and an outlet-side valve box 2 having an outlet 12. Divided into two
A square groove 6 is formed over the entire outer periphery of the lower portion of the outlet side valve box 2, and an O-ring groove 10 is provided therebelow. 8, a cap nut 4 having a concave portion 7 and a female screw 14 therein, and having a square ring insertion opening 8 opened at the lower end of the concave portion 7 is inserted laterally. A U-shaped square ring 5 as shown in FIG. 2 is inserted. The square ring 5 is fitted into the square groove 6 of the outlet side valve box 2 and the square ring 5 is housed in the concave portion 7 to prevent the square ring 5 from escaping sideways. The cap nut 4 locked by the square ring 5 is screwed into a male screw 15 at the upper end of the inlet-side valve box 3 to connect the outlet-side valve box 2 and the inlet-side valve box 3. Reference numeral 9 denotes an O-ring for preventing water leakage, and reference numeral 13 denotes a valve body, the details of which are omitted since their configuration is not directly related to the gist of the present invention. Depending on the valve structure, a square groove 6 may be provided in the inlet side valve box 3 and a male screw 15 screwed to the cap nut 4 may be provided in the outlet side valve box 2. Also, the inlet side valve box and the outlet side may be provided. The valve box may be turned upside down.

[0007]

As described above, in the present invention, the valve box is divided into the inlet side and the outlet side, and the angular ring is fixed by the cap nut and the inlet side or the outlet side, and the outlet side or the inlet side is fixed. The corner ring prevents it from slipping out and is rotatably mounted.Therefore, there is no increase or decrease in rotational friction due to the degree of tightening of the cap nut, and it can always rotate freely with a constant force. By providing a ring insertion port and inserting the square ring from the side of the cap nut, it is possible to shorten the span from the square groove of the valve box to the outlet or the inlet, so that the valve box itself can be shortened accordingly. it can.
