Description

[Detailed description of the invention] (Field of industrial application) This invention is a fixing means for attaching and removing faucets of sanitary equipment, especially vertical mixer faucets, to the top plate of a washbasin or sink. It is related to.

(Prior Art) An example of a conventional vertical mixing faucet mounted on the top plate of a washbasin or the like is shown in FIG. 1 of Japanese Utility Model Publication No. 60-20691 (FIG. 2 of the drawings of the present application). To briefly explain FIG. 2 above, a pair of insertion holes 41, 41a are drilled in the top plate 40 of the washstand, and the insertion holes 41, 41a are the same as the insertion holes 41, 41a.
Bolts 44, 44 have a pair of arms 39, 39 and grooved bars 38, 38.
After attaching to the top plate 40 via
0, its cover 45 and the arm 3
9 and 39 are connected by screws 46 and 46.

The above items have a large number of parts,
Each component must be individually assembled and attached to the top plate, which requires a lot of work during construction, and the large number of components also complicates the management of the distribution process.

(Problem to be solved by the invention) The problem to be solved by the invention is to make it possible to easily attach the body of the vertical mixing faucet to the top plate of the washbasin or sink, and to improve the assembly process and construction. The purpose is to make it easy to eliminate a malfunction or replace it with a different model of mixing faucet.

(Means for Solving the Problems) The technical means taken by the present invention to solve the above problems is to provide a pair of mounting holes at a required interval on the washbasin or the top plate of the sink, and separately A connecting pipe to which the main body of the vertical mixing faucet is attached is provided separately from the main body, and this connecting pipe has a flow path that penetrates the inside in a straight line, and a valve seat with a check valve in the middle of this flow path. Around this valve seat, a blind nut thread is provided at the fluid outlet and the end of the flow path, and a fitting cylinder is provided on the upper part of the outer periphery to be fitted with the fitting openings at both ends of the main body of the vertical mixing faucet. This connecting pipe is equipped with a flange part for positioning, and a long male thread part.After this connecting pipe is attached to the top plate in advance and fixed via the flange part and nuts, the fitting openings on both sides of the main body are attached to the connecting pipe. The main body is fitted into the fitting cylindrical portion and a blind nut is attached to each screw hole of the connecting tube, so that the main body can be easily attached to and removed from the top plate via the connecting tube.

(Function) In the present invention, a connecting pipe is installed in advance on the top plate of a washbasin or sink, and the fitting openings provided at both ends of the vertical mixer faucet are fitted into the fitting cylinder of the connecting pipe. After fitting, the vertical mixing faucet can be easily installed and removed by screwing a blind nut into the threaded opening on the end surface of the connecting pipe.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

The connecting pipe 1 according to the embodiment of this invention has a long cylindrical shape as shown in FIG. A plurality of fluid outlets 31 are opened around the valve seat 30, and the upper part of the flow path 3 (in the figure)
has a threaded opening 7 for attaching a blind nut 14 to connect the main body 8 of the vertical mixing faucet B to the connecting pipe 1, and the connecting pipe 1 has fitting openings (described later) on the upper and lower sides of the outer peripheral surface thereof. A fitting cylinder part 15 is provided to be fitted with 12,
It has an annular flange portion 2 and a long male threaded portion 6 connected to the fitting cylinder portion 15. It has an outer diameter that can be inserted into a pair of mounting holes 17a drilled at intervals, and is smaller in diameter than the flange portion 2, and is secured by a washer 4 and a nut 5 screwed onto the flange portion 2 and the male threaded portion 6. It is attached to the top plate 17, and one of the male threaded parts 6 is connected to a pipe leading to a water heater, and the other male threaded part 6 is connected to a water pipe (both not shown). The main body part 8 of the vertical mixing faucet B is of a single lever type, and has a discharge pipe 9 and an operation part 10 for adjusting the temperature and flow rate at the upper part, and mixing chambers 11 on the hot water side at both ends of the main body part 8.
and the connecting pipe 1 in the water side mixing chamber (not shown).
A fitting opening portion 12 for fitting the fitting cylinder portion 15 of
The mixing chamber 11 on the hot water side and the water side and the connecting pipe 1 can be connected in a watertight manner by means of a seal ring 13. Said blind nut 14
has a male threaded portion 6a corresponding to the threaded opening 7 of the connecting pipe 1 on its lower outer circumferential surface, and is connected to the connecting pipe 1 in a watertight manner by a seal ring 13a.

Note that the symbol "16" shown in FIG. 1 indicates the valve stem.

Now, to explain the case where the main body part 8 of the vertical mixing faucet is fixed to the top plate 17 of the washstand or sink A, the connecting pipe 1 shown in FIG. 1 is inserted into the mounting hole 17a of the top plate 17 from above. Then, the male threaded portion 6 is exposed to the lower side of the top plate 17. Next, after passing the washer 4 through the male threaded part 6 of the connecting pipe 1 from the bottom of the top plate 17,
The pair of connecting pipes 1 are fixed to the top plate 17 by screwing and tightening the nuts 5 into the male threaded portions 6. Next, the fitting cylinder part 15 of the connecting pipe 1 is inserted into the fitting openings 12 provided at both ends of the main body part 8 of the vertical mixing faucet B.
At this time, a seal ring 13 is provided between the mixing chamber 11 on the hot water side of the main body 8 and between the mixing chamber on the water side and the connecting pipe 1, so that watertightness is maintained. Subsequently, the body portion 8 can be stably fixed to the top plate 17 by screwing a separately provided blind nut 14 into the threaded opening 7 of the connecting pipe 1.

(Effects of the invention) Since the present invention has the above configuration, it has the following advantages.

(1) Make a pair of mounting holes in the top plate of the washbasin or sink, attach a connecting pipe, and fit the fitting openings at both ends of the main body of the vertical mixing faucet into the fitting cylinder of the connecting pipe. In addition, since they are joined using blind nuts, the number of parts can be reduced, and the assembly process can be simplified.
Productivity and construction efficiency can be greatly improved by quickly performing installation and removal work during installation and troubleshooting.

(2) Also, even if you need to replace the vertical mixing faucet with a different model, there is no need to replace it as the connecting pipe is fixed to the top plate. Since all you have to do is attach the stopper, anyone can easily replace the model.

(3) If you forget to drain water at night in water supply equipment in a cold region, and the main body of the mixing faucet freezes, remove the blind nut from the top of the top plate. It can be easily duplicated by removing the main body from the connecting pipe and freezing it, and the effect is great that anyone can easily do this.
