Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a nozzle device that is incorporated into a road snow melting device, a water sprinkler device, or the like.

[Conventional technology]

The same inventor as the present inventor provided the industry with a type of block body operated with a hexagonal wrench as shown in Japanese Patent Application No. 100254/1983.

[Problem that the invention seeks to solve]

The conventional type described above is shown in FIG. 5, and has the inconvenience of not being able to check the amount of water being spouted while operating the hexagonal wrench.

[Means for solving problems]

The present invention includes a cylindrical outer casing with a bottom, a top body that is inserted into the outer casing so that it can be twisted freely and cannot be removed, and has a spouting hole on the top surface, and a bottom part of the top body and a wall of the outer casing. A water guide hole and an inlet hole are provided so that they communicate when the frame reaches a predetermined rotation angle, but do not communicate when the rotation angle reaches another angle, and glasses whose outer periphery at the upper end of the frame is formed into a prismatic shape. The gist is that the wrench fitting part is provided, and the above-mentioned problems are solved by the gist.

〔Example〕

The embodiment shown in the figure has a slot 2 on the opening edge of an outer casing 1 having a cylindrical shape with a bottom, a male thread 3 on the entire outer periphery, and a female thread 4 on the upper side of the inner periphery at the middle height of the inner periphery. Step portions 5 are provided on the lower sides of the respective sections, and a short round rod-shaped block 7 having a first flange 6 at an intermediate height is rotatably inserted into this outer casing 1. An O-ring 8 is inserted between the outer circumferential surface of the outer casing 1 and the inner circumferential surface of the intermediate height portion of the outer casing 1, and the O-ring 8 is in pressure contact with the step portion 5 and the first flange 6 on both sides. A second hexagonal flange 9 for fitting a box wrench (not shown) around the upper end.
This male threaded ring 10 is screwed onto the female thread 4 in the outer casing 1, so that the lower surface of the male threaded ring 10 is in contact with the upper surface of the first flange 6, and The upper half of the piece 7 is fitted into the inner diameter hole 11 of the screw ring 10, and this fitted part 13 is made not to protrude above the inner diameter hole 11. Furthermore, a deep water spout hole 14 is provided on the upper surface of the above-mentioned piece body 7, and an inclined water guide hole 15 and an inlet hole for snow melting water are provided on the bottom surface of this water spout hole 14 and at the bottom corner of the outer casing 1. 16, and these water guide holes 15 and inlet holes 16 communicate with each other when the rotation angle of the frame body 7 reaches a predetermined angle and exhibit an open state, and when the rotation angle reaches other angles, they do not communicate and are in a closed state. Furthermore, since the different embodiment shown in FIG. 6 is almost the same as the above embodiment, the same parts are given the same reference numerals and detailed explanation thereof will be omitted. . Incidentally, FIG. 6 shows an example in which a water spray member is not used together.

[Effect]

Since the present invention has the above-described configuration, for example, as shown in FIG.
Internally threaded riser pipes 22 are erected at various locations, and female threads 2 are carved in the upper end of the internally threaded riser pipes 22.
3 is screwed onto the male screw 3 provided on the outer periphery of the outer casing 1 to attach the whole to the riser pipe 22, and the riser pipe 2
A water sprinkling member 24 having an oblique water spout 24' inside the outer end of the water sprinkling member 24 is screwed onto the water sprinkling member 24 so as to be freely twistable and detachable. In this way, when the inlet hole 16 and the water guide hole 15 are in communication, a part of the water flowing inside the water pipe 21 passes through the inlet hole 16 → the water guide hole 15 → the water outlet hole 14 and is sprayed from the water fountain 24'. be done. Furthermore, when the water spraying member 24 is temporarily removed and the male screw ring 10 is loosened with a box wrench (it may be kept loosened to the extent that the top body 7 can be rotated at all times), the top body 7 is By inserting a box wrench into the hexagonal prism-shaped fitting part 13 and twisting the block body 7, the effective communication cross-sectional area between the inlet hole 16 and the water introduction hole 15 can be widened or narrowed, and the water flow from the water spout hole 14 can be increased or decreased. It is possible to increase or decrease the amount of water spouted while visually checking it, or to stop water spouting by setting the same area to zero, that is, a non-communicating state. Furthermore, if it is desired to change the direction of water sprinkling, this can be done by rotating the water sprinkling member 24 to change the direction of the water fountain 24'. Moreover, if it is desired to spray water directly above, this can be done by removing the water spray member 24.

Note that 26 in the figure indicates a hole for hooking a pin spanner used when twisting the water spraying member 23.

〔Effect of the invention〕

Since the present invention is as described above, it has an excellent effect of completely achieving the intended purpose.
