Description

[Detailed Description of the Invention] The present invention relates to an orienting device for an antifreeze water faucet, in which the directions of an inlet and an outlet can be freely changed.

Conventionally, the valve box part of the antifreeze water tap is buried in the ground,
For convenience of construction, it is required to be able to freely change the direction of the inflow port and the outflow port. Therefore, for example, as shown in FIG. 1, a valve box a is provided with an upper valve box c having an outflow port b and a flow box. Entrance d
An elastic metal ring with a separated end, for example, a circle, which is divided into two lower valve boxes e each having a semi-circular groove f formed in the lower outer peripheral portion of the upper valve box c. The cap nut h locked to the ring g is screwed into a male screw formed on the outer peripheral portion of the upper end of the lower valve box to connect both valve boxes. A method of loosening and rotating the inlet and the outlet to select an appropriate position is generally used. However, in the above method, in order to prevent the upper and lower valve boxes from being misaligned and making it difficult for the piston i to move up and down, it is necessary to tighten the cap nut h thereafter to firmly fix the upper and lower valve boxes. Yes,
Since it has to be done in the ground, the operation is complicated, and forgetting to tighten the cap nut, the upper and lower valve boxes are misaligned, the handle operation becomes very heavy, or conversely, the cap nut is tightened too much, It often happened that the valve box was narrowed and the steering wheel operation became heavy.

In view of the above points, the present invention has an object to provide an antifreeze faucet orientable device in which the direction of the inflow port and the outflow port can be freely selected, and moreover the cap nut need not be tightened. The present invention will be described with reference to the embodiments shown in the drawings.

FIG. 2 shows an embodiment of the present invention, in which a valve box 1 is divided into an upper valve box 3 having an outlet 2 and a lower valve box 5 having an inlet 4. The upper valve box 3 has a drain port 6 on the upper side, cylinders 7, 8 and 9 inside, and a cylinder 10 on the lower valve box 5. The valve box 1 has a communication hole 11 therein, and accommodates a piston 16 having O-rings 12, 13, 14, 15 sliding on the cylinder, and the piston 16 moves up and down to open the plug. I try to select the drainage condition. A square groove 17 is formed in the lower portion of the upper valve box 3 over the entire circumference, and a step portion 18 is formed below the square groove 17. A cap nut 20 that is engaged with the above-mentioned square groove 19 that fits in the square groove 17 is screwed into a male screw 21 formed at the upper end of the lower valve box 5 to connect both valve boxes. Further, a fixing nut 22 screwed onto the male screw 21 prevents the screw from loosening.
When assembling, first insert the cap nut 20 into the upper valve box 3, then install the square ring 19 that is halved from the side, and then attach the cap nut 20 to the male screw 21 in which the fixing nut 22 is screwed in advance. By screwing, the step portion 18 of the upper valve box 3 contacts the upper end portion 23 of the lower valve box 5 so that the cap nut 20 does not rotate at a position where both valve boxes can rotate with a certain hardness. Then, the fixing nut 22 may be tightened. When the span of the outflow port 2 and the inflow port 4 is short and the cap nut 20 cannot be raised too much, the bifurcated square ring 19 is formed in the square groove 17 by lifting the cap nut 20 to the opposite side of the outflow port 2. Since it has to be mounted, it is necessary to take measures such as shortening the circumferential length of the square ring 7 or dividing the square ring 19 into three in some cases.

Depending on the valve structure, the vertical positional relationship between the inflow port 4 and the outflow port 2 may be reversed, and a male screw is formed on the upper valve casing 3 and a fixing nut 22 is screwed into the lower valve casing 5 to form a square groove. 17 is formed, and the cap nut 20 is attached to the square ring 17 that is mounted in the square groove 17.
The positional relationship may be reversed by, for example, locking up. In addition, 24 is an O for preventing water leakage which is attached to the lower valve box
A ring, which may be mounted on the upper valve housing 3.

Since the present invention has the above-mentioned structure, for example, as compared with the case of using the elastic metal ring with the end cut off, that is, the elastic circular ring shown, as shown in the conventional example of FIG. Since the degree of freedom with respect to rotation of the nut 20 and the upper valve box 3 is reduced, the misalignment of the upper valve box 3 and the lower valve box 5 is less likely to occur, and the cap nut 20 is previously set in advance.
In the state where the step portion 18 and the upper end portion 23 are in contact with each other, the contractor is tightened until the core is not displaced and the hardness is such that it can rotate, and the fixing nut 22 is used for fixing. Since you can select any orientation without loosening or tightening the piston, you can save a lot of work and reduce misalignment due to forgetting to tighten it, or over-tightening the cylinder 9 It is possible to prevent an accident such as a malfunction of the steering wheel 16 and the steering wheel becoming hard.

Further, conventionally, as shown in FIG. 1, the inner upper surface of the cap nut h screwed from the position of the upper end surface of the lower valve box e to the male screw portion provided on the upper outer periphery of the lower valve box e. The outer peripheral surface portion near the lower end portion of the upper valve box c from the upper end portion of the circular ring g fitted in the groove 5 having a semicircular cross section provided in the lower outer peripheral portion of the upper valve box c in the distance between The upper valve box and the lower valve box with respect to each other in a state in which a part up to a part facing the upper end surface part of the lower valve box e can be inserted into Although it can rotate, since the elasticity of the elastic circular ring is used, even if the elasticity of the elastic ring itself is useful for the locking, the vertical movement of the piston i that requires reciprocation is required. Antifreeze supply, which is rather harmful for movement and requires extreme avoidance of misalignment during use. I have been struggling with the countermeasures for the stoppers, but as one countermeasure, even if it is possible to reach a certain degree by making the processing precision of the parts sufficiently high with extremely high precision, it is costly to raise the precision more than necessary. In particular, when the elasticity of the elastic ring having a circular cross section is used, there is a drawback in that it is meaningless from a certain point of time to make it highly accurate in relation to the elastic range. In order to eliminate the drawback, the antifreeze water faucet according to the present invention divides the valve box into two, and forms a groove such as a square groove on the outer peripheral portion of one of the valve boxes. A plurality of rings are fitted in the groove and locked by the inner upper surface of the cap nut, and the male nut formed on the outer circumference of the other valve box is fixed by a fixing nut that fixes the cap nut at an appropriate position. Although the directions of the inlet and the outlet can be freely selected, there is an effect that the problem of misalignment during use can be properly and surely selected for the directions of the outlet and the inlet.
