Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a discharge device installed at the tip of the discharge pipe of various faucets.

[Conventional technology]

BACKGROUND ART Conventionally, a discharge device equipped with a foam cap, a heat insulating cap, etc. has been attached to the tip of the discharge pipe of faucets such as single faucets and mixed faucets for hot and cold water to accommodate various conditions.

As an example of this dispensing device,
There is something described in the No.

This is a water mixing faucet equipped with a heat insulating cap and a rectifying network on the water discharge pipe.As shown in Fig. 4, a female screw hole 51 is provided on the lower surface of the distal end side of the water flow pipe 50, and a heat insulating cap 52 is attached to the water discharge pipe. 50 and is inserted through a hole 53 opened at the lower part of the guide tube 54 to be screwed and connected to this female threaded hole 51. Further, a nut 55 is screwed to the lower end of this guide tube 54 to form a rectifying net 56. It is fixed.

In this way, in the conventional water faucet, the heat insulating cap 52 is first positioned and fixed with respect to the water discharge pipe 50 by the guide tube 54, and then the rectifying net 5 is fixed by the nut 55.
6 is fixed to the guide tube 54 and integrated into the heat insulating cap 52.

[Problem that the invention attempts to solve]

However, since it is necessary to increase the wall thickness of the threaded portion of the water discharge pipe 50 in order to provide the female screw hole 51, the types of the water discharge pipe 50 are limited, and there is a lack of versatility.

Further, since the guide tube 54 requires threading on both ends thereof, there are also problems such as an increase in manufacturing man-hours and an increase in cost.

The purpose of the present invention is to enable a water discharging device to be fixed to a water discharging pipe to be manufactured with a simple structure and at low cost.

[Means and actions for solving problems]

The present invention is a discharge device equipped with a water discharge pipe and a cap that is fitted with a gasket placed on the outer periphery of the distal end of the water discharge pipe. A cylindrical part with a thread formed thereon is formed downward, and a guide cylinder whose upper end passes through a hole in the water discharge pipe is inserted into the cylindrical part, and a stepped part engages with the inner wall of the cylindrical part on the circumferential surface of the guide cylinder in the insertion direction. and a nut that presses the guide cylinder in the direction of the water discharge pipe is connected to a male screw of the cylinder part, and by screwing the nut into the cylinder part of the cap, the cap can be fixed to the water discharge pipe. This is what I did.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a side view of a hot water mixing faucet equipped with a water discharging device according to the present invention, and FIG. 2 is an enlarged sectional view of the main parts of the discharging device.

In the figure, reference numeral 1 is the faucet body, in which two ceramic valve plates are placed one over the other, one of which is moved by a lever handle 2 to open and close the flow path, and mix hot water and water. It is a single lever type that allows you to change the ratio.

3 is a water discharge pipe that is rotatably attached to the bottom of the faucet body 1. In this example, it is a thin-walled brass pipe that is bent and has a plated surface, and a bushing 4 is attached to the tip.
A hole 5 is formed on the lower surface of the tip end, and an annular groove 6 formed by drawing is further provided.

Reference numeral 7 denotes a cap that is inserted into the tip of the water discharge pipe 3, and is made of ABS resin and is insulating so that the water discharge pipe 3 can be rotated by touching the cap 7 even when water is being discharged at a high temperature.

This cap 7 has a cylindrical portion 9 extending downward coaxially with a communication hole 8 with the inside, and a male screw 1 attached to the outer periphery of the lower end of the cylindrical portion 9.
0 is provided and formed, and a cap 7 is placed inside this cylindrical portion 9.
A guide tube 11 is inserted for positioning and fixing the water to the water discharge pipe 3.

As shown in the perspective view of FIG. 3, the guide tube 11 is a cylindrical body with different outer diameters on the circumferential surface, and has an annular step 12 formed in the middle and four protrusions in the axial direction at the bottom. Article 13 has been established. This guide tube 11 is inserted through the communication hole 8 of the cap 7 and the hole 5 of the water discharge pipe 3 to position and fix the cap 7 to the water discharge pipe 3. still,
The protrusion 13 is provided so that when the guide tube 11 is inserted into the tube section 9, its side surface presses against the inner circumferential surface of the tube section 9. It is possible to prevent it from falling off.

Furthermore, 14 is a nut that is screwed into the male screw 10 of the cylindrical portion 9, which tightens the guide tube 11 in the three directions of the water discharge pipe together with the packing 15 and the three straightening nets 16, and tightens the guide tube 11 in the three directions of the water discharge pipe. The cap 7 can be pressed and fixed in the direction of the water discharge pipe 3 by the force of engagement with the inner wall 9a.

In addition, when installing the cap 7, the water discharge pipe 3
Place the gasket 17 in the groove 6 of the cap 7.
Prevent water leakage from the ends.

In the above structure, the cap 7 can be easily attached by fitting it into the water discharge pipe 3, and after positioning it using the guide tube 11, screwing the nut 14 into the tube portion 9.

Further, compared to the conventional one, only the male screw 10 of the cap 7 requires screw processing, so that the number of manufacturing steps can be reduced.

Furthermore, since the spout pipe 3 does not require thread cutting, the cap 7 can be attached to a thin-walled pipe or one made of cast metal, and the shape of the cap 7 can be changed to the shape of the spout pipe 3.
The cap 7 can be connected without regard to the shape of the water discharge pipe 3 as long as it is manufactured according to the requirements.

In the above embodiments, the discharge pipe of a hot water mixing faucet has been described, but the discharge device of the present invention can also be applied to other faucets.

[Effect of idea]

This invention has the effect of reducing the cost of faucets by reducing the man-hours required to manufacture the parts of the discharge device and simplifying the assembly work, and also improves versatility since it can be applied to various types of water discharge pipes. play.
