Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antifreeze faucet device that allows the orientation of an inlet and an outlet to be freely changed.

Conventionally, the valve box of antifreeze faucets is buried underground, so for construction reasons, it is necessary to be able to freely change the direction of the inlet and outlet. As shown, the valve body a is divided into an upper valve body c having an outlet b, and a lower valve body e having an inlet d.
A cap nut is divided into two parts, and is engaged with a resilient metal circular ring g whose end is cut off, which fits into a semicircular groove f provided on the lower outer periphery of the upper valve case c. Connect both valve boxes by screwing h into the male screw formed on the outer periphery of the upper end of the lower valve box.If you want to freely change the orientation during construction, loosen the cap nut h and rotate the inlet and outlet. The common method was to select an appropriate position by letting the

However, in the above method, in order to prevent the upper and lower valve boxes from misaligning and making it difficult for the piston i to move up and down, it is necessary to tighten the cap nuts h to firmly fix the upper and lower valve boxes. The operation is cumbersome as it has to be done underground.Also, if you forget to tighten the cap nut, the upper and lower valve boxes may become misaligned, making the handle operation very difficult, or conversely, the cap nut may be tightened. Over time, the valve box will become smaller and the steering wheel will become harder to operate.
Things like this often happened.

In view of the above points, the purpose of the present invention is to provide a device for freely directional anti-freeze faucets that allows the orientation of the inlet and outlet to be freely selected and eliminates the need to tighten the cap nut. , the present invention will be explained based on the embodiments shown in the drawings.

FIG. 2 shows an embodiment of the present invention.
In the figure, a valve box 1 includes an upper valve box 3 having an outlet 2,
It is divided into two parts, a lower valve box 5 having an inlet 4, and an upper valve box 3 having a drain port 6 on the upper side and cylinders 7, 8, 9 inside. A cylinder 10 is formed at 5. The valve box 1 has a communication hole 11 inside and houses a piston 16 equipped with O-rings 12, 13, 14, 15 that slide on the cylinder, and the piston 16 moves up and down to open the valve. I am trying to select the drainage state.
A small diameter male screw 17 is formed in the lower part of the upper valve box 3,
An outer cylinder 18 is formed at the lower end. A cap nut 20 latched to a retaining nut 19 connected and fixed to the small-diameter male screw 17 is screwed onto a large-diameter male screw 21 formed at the upper end of the lower valve box 5 via adhesive, and both valves are screwed together with an adhesive. It connects the boxes and prevents the screws from loosening. When assembling, first insert the cap nut 20 into the upper valve box 3, then connect and fix the retaining nut 19 to the small diameter male screw 17, and attach the lower valve box to the lower valve box, which has been coated with slow-drying adhesive in advance. Screw the cap nut 20 onto the male diameter screw 21, and screw the cap nut 20 to a position where the lower end of the retaining nut 19 contacts the upper end of the lower valve box 5 and both valve boxes can rotate with a constant stiffness. If you tighten it and leave it as it is, the adhesive applied to the large diameter male screw 21 will dry, and the cap nut 20 and the lower valve box 5 will be firmly attached.
The screws will never come loose. The adhesive is Fukuronatsu 20.
After the position of the large-diameter male screw 21 is determined, a quick-drying adhesive can be injected into the large-diameter male screw 21 to fix it. Similarly, the retaining nut 19 may be more firmly fixed with an adhesive. Depending on the valve structure, inlet port 4
The vertical positional relationship of the outflow port 2 may be reversed,
In addition, the positional relationship is determined by forming a large-diameter male thread 21 on the upper valve box 3, a small-diameter male thread 17 on the lower valve box 5, connecting and fixing the retaining nut 20, and locking the cap nut 20 upward. may be reversed.
Note that 22 is an O-ring for preventing water leakage that is attached to the lower valve box 5, and this can also be attached to the upper valve box 3.

Since the present invention has the above configuration, the degree of freedom for rotation of the cap nut 20 and the upper valve box 3 is reduced compared to, for example, a case where a circular ring as shown in the conventional example shown in FIG. 1 is used. This makes it more difficult for the upper valve box 3 and the lower valve box 5 to become misaligned, and it is also possible to insert the cap nut 20 in advance with the lower end of the locking nut 19 in contact with the upper end of the lower valve box 5. Since it is tightened until it is hard enough to rotate without causing displacement and is fixed with adhesive, the construction contractor can select any orientation without loosening or tightening the cap nut 20. This saves a lot of work and prevents accidents such as forgetting to tighten and causing misalignment, or over-tightening causing the cylinder 9 to shrink, causing malfunction of the piston 16 and making the handle stiff. It has the effect of being able to prevent it from happening.
