Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge pipe which is watertight and freely detachable from a water passage through an insertion member having a net portion such as a flow straightening means, a strainer and the like.

[0002]

2. Description of the Related Art Conventionally, a flow regulating network is provided to supply water at a uniform flow rate and flow rate to a water discharge port of a water discharge pipe. In a conventional mounting structure of a rectifier net, if the water outlet is circular, there is a mounting structure by screwing.

[0003] When the water outlet is non-circular, it is impossible to screw it in.
In the case of a water discharge pipe described in JP-A-604, a net is fixedly arranged in a water passage, and a lid is fixed with screws via a flat packing.

[0004]

In the case where the water outlet is circular, the conventional installation of the flow straightening network requires time and labor by forming screws for screwing the flow straightening net and mounting by screwing. In the case of a non-circular shape, the installation structure of the rectifier net is complicated, and it takes time to attach or remove the rectifier net.

[0005] The present invention provides a water discharge pipe which can be easily attached to and detached from a water passage through an insertion member having a net portion.

[0006]

According to the present invention, there is provided a water discharge pipe comprising an opening of a water passage, a sealing portion of the opening, a mesh portion crossing the inside of the water passage, and holding means for holding the opening. Having an insertion member.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A water discharge pipe in which an insertion member having a net-like portion according to the present invention is inserted uses a frictional force between an opening side wall and a seal member as a holding means.

The sectional shape of the water passage of the water discharge pipe of the present invention can be not only circular but also flat.

In the water discharge pipe of the present invention, an insertion member having a net-like portion is detachably inserted into a passage of the water discharge pipe in a watertight state.

As an insertion member having a net portion according to the present invention, for example, a strainer and a rectifying net are constituted by a block-shaped stop portion and a net portion erected from the stop portion, and a sealing member is provided around the sealing portion. To make the sealing portion and the opening of the water discharge pipe watertight and detachable.

As a material of the flexible tube 3, for example, vinyl chloride, resin, rubber can be used. In addition, outer shell 2
For example, a metal or resin is used, but water is not passed through the outer shell 2 and water is passed through the flexible pipe 3 and the rectification mechanism 5 as an inner pipe that serves as a water passage. Since it is not necessary to increase the thickness of the second member 2 and it is possible to make the second member thinner, it is possible to form a double structure without increasing the outer shape, so that material costs can be reduced.

FIG. 2 shows an embodiment of the rectifying mechanism of the water discharge pipe according to the present invention. FIG. 2A is a cross section, and FIG. 2B is a cross section taken along line BB of FIG. Fig. 2- (c) is a perspective view of the strainer-equipped cap.

In FIG. 1 and FIG. 2, a rectifying mechanism 5 serving as a water passage has two circular water passages 5a to which the flexible water pipes 3 are connected and an opening 5b of the water passage 5a. The water outlet 5c has a projection 6 near the opening 5b and a mesh net or a punched metal near the water outlet of the water outlet 5c for diffusion and buffering of water flow. And the like.

The flexible water pipe 3 is fitted into the connection part 5d of the two water flow parts 5a of the rectification mechanism part 5, and the hose band 8
After connecting the flow-through flexible pipe 3 and the rectifying mechanism 5 by tightening them, they are passed through the outer shell 2 and fixed with screws 9.

After that, a detachable cap with strainer 10 as an insertion member having a net-like portion is fitted through the outer shell 2 into the rectification mechanism 5 serving as a water passage. As shown in FIG. 2, the strainer-equipped cap 10 has a block-shaped sealing portion 10a on which a strainer 10b serving as a net portion is erected, and an O-ring 10c is provided as a sealing material around the sealing portion 10a. ing. Even if the O-ring 10b of the strainer mounting portion is inserted into the opening 11 of the rectifying mechanism 5, the O-ring 10b is in tight contact with the strainer mounting portion and the opening 11 of the rectifying mechanism 5 and is inserted in a watertight state. No worries about water leakage.

FIG. 3 shows another embodiment of the water discharge pipe of the present invention.
FIG. 3A is a plan view showing a state before the straightening net cap is inserted, FIG. 3B is a front view of the straightening net cap, and FIG.
FIG. 3C is a cross-sectional view taken along the line CC of FIG.

The rectifying net cap 12 has a rectifying net 12b erected on a block-shaped insertion portion 12a, and an O-ring 12c is provided around the sealing portion 12a as a sealing member.
Even if the O-ring 12c of the sealing portion 12a is inserted into the insertion opening 11 of the rectification mechanism 5, the O-ring 12c
It is inserted in a watertight state in close contact with the opening 11 of
No worries about water leakage.

【The invention's effect】

(1) According to the present invention, even if the water outlet is circular or non-circular, the insertion member having a net portion such as a rectifying net and a strainer near the tip thereof is inserted into the opening of the water passage, so that attachment and detachment is easy. become. Also, the insertion position is
Since it is not limited to the vicinity of the tip, the degree of freedom in design also increases.

(2) In contrast to the conventional method in which a flat rectifying net is inserted and the lid is screwed to the ceiling via packing, the insertion member having the net is sealed at the water outlet of the water passage. Since the members are held by the frictional force, attachment and detachment become easy.

(3) When the cross-sectional shape of the water passage of the water discharge pipe is flat, the insertion member of the present invention is inserted into the water passage before the water flow straightening line even if the flow straightening network is fixed immediately before the water discharge port. By providing, it is possible to easily drain water and remove dust.

(4) An insertion member having a net-like portion can be freely and detachably inserted into the opening of the water passage of the water discharge pipe in a watertight state.

Further, since the thickness of the holding portion is small, the water discharge pipe can be made as thin and flat as possible.
