Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in a structure for attaching a water discharge cap provided at a tip of a water discharge pipe in a water tap.

[Prior Art] Conventionally, as a mounting structure of a water discharge cap provided at the tip of a water discharge pipe in a water tap, firstly, as shown in FIG. 7, a water discharge pipe 101 is formed of a thick casting, and the water discharge pipe 101 is formed. An opening 103 for water discharge having a female screw 102 is provided on the peripheral side surface of the end of the water discharge pipe 101, and an opening 104 is provided on the outer periphery of the end of the water discharge pipe 101 so as to be in communication with the opening 103 of the water discharge pipe 101. Fitting the water discharge cap 105, the water discharge cap 105
The guide pipe 106 is screwed to the female screw 102 of the water discharge pipe 101 through the opening 104 of the water discharge pipe 101 and the water discharge cap 105 is attached to the water discharge pipe 101 (Shokai 59-188566). Secondly, as shown in FIG. The water discharge pipe 101 is formed of a thin walled body, a water discharge opening 103 is provided on the peripheral side surface on the end side of the water discharge pipe 101, and the opening 103 of the water discharge pipe 101 is provided at the outer periphery of the end of the water discharge pipe 101.
By fitting a bottomed water discharge cap 105 having an opening 104 that is in communication with and is fitted and passing the rectifying member 107 through the respective openings 103, 104 of the water discharge pipe 101 and the water discharge cap 105 and fixing with a lock nut 108 It is known that the water discharge cap 105 is attached to the water discharge pipe 101 (Shokai 63-100755).

[Problems to be Solved by the Invention] In the above-mentioned first prior art, it is necessary to form the female screw 102 in the opening 103 and the wall thickness of the water discharge pipe 101 must be increased considerably.
There is a problem that it becomes very expensive and heavy and difficult to handle.

Further, in the second conventional technology, since the water discharge pipe 101 can be made thin, there is no problem as in the first conventional technology, but the water discharge cap 105 is removed from the water discharge pipe 101 only by the engagement of the rectifying member 107. Since it is designed not to come off, if the lock nut 108 is removed for the purpose of cleaning the filter 109 of the water discharge cap 105, the rectifying member 107 also loses its support and comes off together, and water is discharged as it is. There was a risk that the water discharge cap 105 would come off. Further, since the cut end of the opening 103 provided in the water discharge pipe 101 is exposed to the flow path, it is likely to be corroded by water, and eventually the water discharge cap 105 may be detached from the corroded portion.

[Means for Solving the Problems] The present invention has been made to solve all of the above-mentioned problems, and an opening for water discharge is provided on the peripheral side surface on the end side of the water discharge pipe in the water tap, and the inside of the water discharge pipe end is provided. A bush having an opening provided to communicate with the opening of the water discharge pipe is inserted in the circumference, and a water discharge port provided to communicate with the opening of the water discharge pipe is provided on the outer periphery of the end of the water discharge pipe. Provided is a water discharge cap mounting structure, in which a water discharge cap having a shape like a shape is fitted, and the bush and the water discharge cap are connected and integrated with each other by an engaging convex ring that passes through an opening of a water discharge pipe.

[Operation] By connecting the bush inserted into the inner circumference of the water discharge pipe and the water discharge cap fitted to the outer circumference of the water discharge pipe by the engaging convex ring that passes through the water discharge opening of the water discharge pipe, the water discharge cap is formed. Fixed at the tip. This connection between the bush and the water discharge cap is maintained without being related to other components, and even if the other components are removed for the purpose of cleaning or the like, the fact that the water discharge cap comes off with it Absent.

Further, since the opening of the water discharge pipe is substantially sealed by the engaging convex ring, it is not exposed to the flow path, and corrosion due to water can be prevented.

[Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings.

The water discharge pipe 1 extending substantially horizontally from the water tap A is a thin-walled metal pipe having an elliptical cross-section and has an open tip, and a water discharge pipe 1 is formed on a lower surface of a peripheral side surface on the end side of the water discharge pipe 1. Opening 2
Is provided. A bottomed bush 3 having an elliptic cylinder shape that can be in close contact with the inner circumference of the water discharge pipe 1 is inserted into the open end of the water discharge pipe 1. The bush 3 is provided with an opening 4 which is in communication with the opening 2 of the water discharge pipe 1 when inserted into the water discharge pipe 1, and is formed with a female screw 5 in the opening 4.

On the other hand, a bottomed water discharge cap 7 provided with a water discharge port 6 that is in communication with the opening 2 of the water discharge pipe 1 is fitted on the outer periphery of the end of the water discharge pipe 1. The water discharge cap 7 is kept watertight by an O-ring 7a provided on the outer circumference of the water discharge pipe 1.

Then, the bush 3 and the water discharge cap 7 are integrated by screwing the engaging convex ring 8 to the female screw 5 of the bush 3 from the water discharge cap 7 side. The engagement convex ring 8 is a cylinder having a water passage hole 9 therein, one end of which has a diameter larger than that of the water discharge port 6 of the water discharge cap 7, and a female screw 10 is formed on the large diameter portion while the other end is formed. A male screw 11 is also formed on the side, and the male screw 11 is screwed into the female screw 5 of the bush 3 through the water discharge port 6 of the water discharge cap 7 and the opening 2 of the water discharge pipe 1 to form the water discharge cap 7, the water discharge pipe 1, and the bush 3. Tighten the people together to join them. An O-ring 12 is interposed between the engaging convex ring 8 and the water discharge cap 7 to be watertight.

A straightening cap 13 is screwed onto the male screw 10 of the large diameter portion of the engaging convex ring 8, and the straightening nets 14 and 14 are attached between the straightening cap 13 and the engaging convex ring 8.

[Embodiment 2] FIGS. 4 to 6 show another embodiment, in which the same reference numerals as those in Embodiment 1 indicate the same members.

The second embodiment is characterized in that the engaging convex ring 8 of the first embodiment is integrally formed with the bush 3.

That is, the bush 3 is formed into a thin-walled cylindrical shape having a single score line 15 in the axial direction so as to have an expanding elasticity as a whole, and further the meat of the discharge pipe 1 is formed on the lower surface of the peripheral edge of the opening 4. A cylindrical engaging convex ring 8 is provided so as to have a height higher than the thickness.

Then, first, the bush 3 is inserted from the opening of the water discharge pipe 1 while slightly deforming the engagement convex ring 8 and the opening 2 of the water discharge pipe 1.
Then, as shown in FIG. 6, the water discharge cap 7 is fitted on the end portion of the water discharge pipe 1 and slid. At this time, the engaging convex ring 8 of the bush 3 projects from the opening 2 of the water discharge pipe 1 to the lower surface, but while the water discharge cap 7 is slid, it is deformed by its elasticity and pressed against the inner peripheral surface of the water discharge cap 7. Abutting. Then, when the opening 2 of the water discharge pipe 1 and the water discharge port 6 of the water discharge cap 7 match at the position where the water discharge cap 7 is completely fitted, the engaging convex ring 8 projects into the water discharge port 6 by its expanding elasticity and engages. Then, the water discharge cap 7 is fixed to the water discharge pipe 1.
