Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a double and two-stage water figure, and
Each relates to a fountain nozzle that causes a separate movement.

[Conventional technology]

Conventionally, in order to obtain a water figure of double inside and outside, or two steps above and below, a large number of fountain nozzles are arranged to form the water figure, or the water injection port and the jet port are separated. The fountain nozzle was used.

Further, in rocking the water figure, it is usual to move the fountain nozzle itself by utilizing hydraulic force or other external force.

[Problems to be solved by the invention]

By the way, arranging a large number of fountain nozzles according to the water shape requires a lot of work, which inevitably leads to a high cost. Was high.

Further, the fountain nozzle itself was moved by a method of rotating or rocking the whole by electric power or hydraulic power, but the structure of the equipment became complicated, the facility became large, and the construction work was troublesome.

Therefore, the present invention intends to provide a fountain nozzle capable of obtaining a double and two-stage water figure with one line and moving the inside and outside water figures separately without requiring any equipment. It is a thing.

[Means for solving problems]

The present invention is directed to an outer pipe having a water injection port formed on the lower side and a discharge port having a large diameter formed on the upper end surface, and a short medium pipe which is built in with a space in the outer pipe and whose outer periphery is attached above the outer pipe. And a plurality of vertical slits opened in the same chord direction at appropriate places on the peripheral wall of the middle pipe, and a head that is loosely fitted in the middle pipe with a space and fits into the discharge port of the outer pipe at the upper end. And an inner tube whose lower part protrudes from the middle tube, a ring which inserts the inner tube and closes the lower end of the middle tube, an ejection port formed on the upper end surface of the head of the inner tube, and a downward projection of the inner tube. It consists of a stopper attached to the outer circumference of the part.

Further, it is preferable that the head portion of the inner tube has an inverted conical shape. Further, it is effective that the ejection port formed on the upper end surface of the head is formed eccentrically from the center of the head. Furthermore, it is preferable that the stopper is vertically adjustable.

[Work]

Thus, the fountain nozzle is attached by connecting it to the pressure water supply pipe, and one of the pressure water from the water injection port exerts a rotational force in one direction from the space between the outer pipe and the middle pipe through the vertical slit. When applied, it reaches the inside of the middle pipe, pushes up the head of the inner pipe, and is ejected from the discharge port of the outer pipe.

At this time, the lifting of the inner pipe is regulated by the stopper, but due to the rotational force generated by the inflow of pressure water from the vertical slit, the entire inner pipe will rotate with an inclination, and the circumference of the jetting part from the spout will be surrounded. Change direction. In addition, the inner pipe also causes rotation of the inner pipe itself due to the rotation, and the other of the pressure water from the water injection port directly flows into the inner pipe, and the head pipe discharges the outer pipe. It will be ejected in a state of being inclined to the side opposite to the ejection from the ejection port. Then, the ejection angle from the ejection port is set by the head shape of the inner pipe, and the ejection distance from the ejection port is regulated by the lifting degree of the inner pipe. The shape of water ejected from the ejection port of the inner tube changes depending on the position of the ejection port formed on the head.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
Is an outer pipe having a water injection port 2 on the lower side and a discharge port 3 having a countersink shape and having a large diameter formed on the upper end surface. The outer pipe 1 has a flange 4 formed on the outer periphery of the upper end. A short medium tube 5 attached above is built in with a space 6 in between. Reference numeral 7 is a vertical slit formed at a proper position on the peripheral wall of the middle pipe 5, and is formed in the same chord direction, that is, in an oblique direction on the peripheral wall. Reference numeral 8 denotes an inner pipe having an inverted conical head portion 9 which is fitted into the countersink-shaped discharge port 3 of the outer pipe 1 from above, and which is loosely fitted in the middle pipe 5 with a space 10 between Is projected from the middle tube 5. Reference numeral 11 is a ring that inserts the inner pipe 8 and closes the lower end of the middle pipe 5, and 12 is a stopper that is attached to the outer periphery of the lower protruding portion of the inner pipe 8 by a stopper 13. The stopper prevents the inner pipe 8 from being lifted upward. The attachment position can be adjusted up and down by operating the fastener 13. Reference numeral 14 denotes an ejection port formed in the head portion 9 of the inner pipe 8, which is slightly eccentric in the circumferential direction.

In the illustrated embodiment, the vertical slit 7 is formed leftward from the peripheral wall surface, but the invention is not limited to this.
Further, although the discharge port 3 of the outer pipe 1 has a countersink shape and the head portion 9 of the inner pipe 8 fitted therein has an inverted conical shape, it can be distinguished from the water ejected from the ejection port 14 of the inner pipe 8. If spouted water can be obtained, it is not necessary to be a combination of both.
Furthermore, it is also conceivable that a plurality of ejection ports 14 of the inner pipe 8 are formed or that the shape and direction are changed.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY The present invention is configured as described above, and double spouted water can be obtained with one fountain nozzle without requiring any special external force, and the outer spouted water can be revolved in an inclined state depending on the inner pipe. While changing the discharge part in the circumferential direction, it is ejected while retaining the rotational force, forming a watery appearance. Moreover,
Due to the revolving of the inner pipe, the ejected position of the inner part of the ejected water will be opposite to the ejected position from the outer pipe discharge port.
You can easily get a compact, water-like appearance from the compact facility.

When the head portion of the inner pipe has an inverted conical shape, the jet angle of the jet water on the outside can be set low, and the jet water on the inside can be clearly distinguished. In addition, because the jet outlet of the head is eccentric in the circumferential direction, the jetting position of the jetted water from the inner pipe, which also revolves in addition to orbiting, is changed, forming a complex and beautiful water figure. You can do it.

Furthermore, since the stopper is attached so that the vertical position can be adjusted, the lift of the inner pipe can be regulated and the ejection distance from the ejection port of the outer pipe can be adjusted. Easily obtained.
