Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a holder for holding and fixing a floatless switch that controls the start and stop of water supply to a water tank used as a water tank.

<Prior Art> Conventionally, the retainer A of this type of floatless switch 11 has a cylindrical shape that fits into a mounting hole 14 perpendicularly drilled in the roof 7 of the aquarium, as shown in FIGS. 5 to 7. The container 1a and the seat 1b to which the floatless switch 11 is screwed are formed separately, and the seat 1b is integrally provided at the upper end opening of the container 1a with adhesive. 1 is formed, the container body 1 is inserted through the mounting hole 14 of the roof 7 of the aquarium, the FRP lining 15 is applied across the outer peripheral surface of the container body 1 and the roof 7, and the container body 1 is attached. , the cap 9 is formed into a box shape with a lower opening larger than the outer circumferential diameter of the seat 1b, and has a mounting hole 1.
After adhering and attaching the L-shaped mounting members 19 to the roof 7 where the two sides of the opening edge of the cap 9 around the opening 4 are located, the two mounting members 19, 19
After fitting the two sides of the opening edge of the cap 9 into the cap, the opening edge was fixed to the mounting member 19 with screws 20 and attached.

Therefore, in this conventional method, it is possible to deal with cases where the roof on which the retainer A is attached is a tapered roof as shown in FIGS. 5 and 6, and cases where it is a flat roof as shown in FIG. Cap 9 and mounting member 1
I had to prepare two types of 9 each.

In addition, the vessel body 1 has a seat portion 1 at the upper end opening of the vessel body 1a.
Since it had to be formed by adhering b, the workability was extremely poor and it was time-consuming. Therefore, it is desirable to integrally mold both of them from a synthetic resin material, but since the seat portion 1b has to be thick because the floatless switch 11 is screwed onto it, both of them are made of a synthetic resin material. If molded integrally, the difference in thickness between the barrel 1a and the seat 1b causes deformation and sink marks on the seat 1b, resulting in drawbacks such as the inability to install the floatless switch 11 accurately. It was something that was happening.

<Problem to be solved by the invention> The problem to be solved by the invention is that whether the roof of the aquarium is tapered or flat, it is possible to use a cage of exactly the same shape. Moreover, it is an object of the present invention to provide a floatless switch holder which prevents deformation or sink marks from occurring in the seat part even if the barrel and seat part are integrally molded from a synthetic resin material, and which is easy to install.

<Means for solving the problem> The technical means taken by the present invention to solve the problem is to attach a flange-shaped seat to the barrel that is inserted into the mounting hole drilled vertically in the roof of the aquarium. Consisting of a container body formed by integrally providing the container body, and a cap that covers a floatless switch that is screwed onto the upper surface of the seat portion by fitting around the outer periphery of the seat portion of the container body, The container body is formed by integrally molding a flange-shaped seat part on the container barrel and its upper end opening from synthetic resin, and the seat part has a screw hole for mounting a floatless switch in the center part. A first annular groove and a second annular groove are formed on the outer periphery of the mounting screw hole to be concentric with the container body, and the first annular groove is formed in a seat directly above the connecting portion with the container barrel. The second annular groove is recessed in the outer periphery of the first annular groove, and the lower opening is made of a synthetic resin material. A cap formed in a truncated conical shape corresponding to the outer periphery of the seat is fitted onto the outer periphery of the seat, and a cord hole is bored at approximately the center of the circumference, and the second
It is characterized in that an appropriate number of through holes communicating with the outside are bored in the bottom and sides of the annular groove.

<Function> The present invention consists of a body made of synthetic resin, in which the seat for screwing the floatless switch and a cylindrical vessel are integrally molded, into a mounting hole drilled vertically in the roof of the aquarium. Attach the cap by inserting it through the seat, and also by fitting the opening of the cap into the outer periphery of the seat and hooking it.

If the roof of the aquarium to which the retainer is attached is tapered, the through hole bored at the bottom of the second annular groove recessed in the seat will drain rainwater etc. that has entered the cap from the cord hole to the outside. If the roof of the aquarium is flat, it also functions as a bolt insertion hole when fixing the seat to the top surface of the roof with bolts, and drains rainwater etc. that has entered the cap through the cord hole. is discharged to the outside through a through hole bored in the side of the second annular groove.

In addition, by making the bottom thickness of the first annular groove approximately the same as the thickness of the container barrel, the hardening that acts on the bottom of the first annular groove when the container barrel and seat are integrally molded from synthetic resin can be made. The shrinkage rate is set to be approximately the same as the shrinkage rate that acts on the part of the barrel connected to the seat.

<Example> An example of the present invention will be described based on FIGS. 1 to 4. In the figures, A is a floatless switch holder, 7 is the roof of the water tank, and the holder A is a cylindrical container. A container body 1 having a flange-like seat portion 1b integrally attached to a cylinder 1a, and a seat portion 1 that is fitted onto the outer periphery of the seat portion 1b.
b, and a cap 9 that covers the floatless switch 11.

The vessel body 1 is made of synthetic resin and has both upper and lower ends open, and its outer circumference has a mounting hole 1 bored perpendicularly to the roof 7 of the aquarium.
A flange-shaped seat portion 1b is integrally formed at the upper end opening of a cylindrical container 1a having approximately the same diameter as the container 4.

The seat part 1b is for screwing and installing the floatless switch 11, and is formed to have a thick wall and a tapered shape with its outer peripheral surface expanding downward. At the same time, a locking step 3 is formed that projects outwardly, and a screw hole 18 for mounting the floatless switch 11 is formed in the center, and a screw is carved into the inner circumferential surface of the screw hole 18.

Further, two annular grooves, a first annular groove 4 and a second annular groove 5, which are concentric with the axis of the vessel body 1, are provided on the upper surface of the seat portion 1b.

The first annular groove 4 is recessed from the upper surface of the seat portion 1b immediately above the connecting portion between the container barrel 1a and the seat portion 1b, so that the thickness of its bottom portion is approximately the same as the thickness of the container barrel 1a. I'll make it like that.

Further, an appropriate number of through holes 6, 17 communicating with the outside are bored in the second annular groove 5 on the outside.

The holes 6 were drilled so as to pass vertically from the bottom surface of the second annular groove 5 toward the lower surface (thickness direction) of the seat portion 1b, and were provided at equal intervals in the groove direction. On the other hand, the through holes 17 are formed so as to penetrate horizontally from the lower part of the inner circumferential surface of the second annular groove 5 toward the outer circumferential surface of the seat part 1b, and are provided at equal intervals in the groove direction. do.

The cap 9 is used to protect the floatless switch 11, which is screwed onto the upper surface of the seat 1b of the device body 1, from being exposed to wind and rain. It is formed into a truncated conical shape with a blind upper surface corresponding to the truncated cone shape, and a cord hole 10 for pulling the cord is bored in the approximate center of the circumferential surface, and a seat portion is formed at the lower circumferential surface of the lower surface opening. A hole is provided at a location corresponding to the through hole 17 of 1b to connect the through hole 17 to the outside.

Thus, the floatless switch holder A is installed by inserting the barrel 1a of the container 1 through the mounting hole 14 drilled in the roof 7 of the aquarium, and then inserting the barrel 1a of the container 1 into the mounting hole 14 drilled in the roof 7 of the aquarium. The floatless switch 11 is screwed into the hole 18, and the electrode 12 of the floatless switch 11 is inserted through the vessel body 1 to hang down inside the aquarium, and the floatless switch 11 is connected through the cord pulled in from the cord hole 10. Contact power supply.

Note that the first annular groove 4 of the seat portion 1b is closed by the flange portion 13 of the floatless switch 11.

When installing the floatless switch holder A on the roof 7 of the aquarium, if the roof 7 is tapered, the floatless switch holder A should be installed in a mounting hole 14 perpendicular to the roof 7 as shown in FIG. The container 1a of the body 1 is inserted through the container 1a, and the container 1a is inserted between the outer peripheral surface of the container 1a and the roof 7.
FRP lining 15 is applied to the seat part 1b and the roof 7
Then, the cap 9 is fitted and inserted into the outer periphery of the seat part 1b, and the lower edge of the opening is brought into contact with and latched to the latching step 3 of the seat part 1b.

In addition, when the roof 7 is flat, as shown in FIG.
4 to make the bottom surface of the seat part 1b come into contact with the top surface of the roof 7, and then insert the bolt 8 into the through hole 6 in the bottom surface of the second annular groove 5 provided in the seat part 2 to penetrate the roof 7. , tighten the nuts 16 to fix it to the roof 7.

In this case, rainwater or the like that has entered the cap 9 through the cord hole 10 is discharged to the outside through a through hole 17 bored in the side of the second annular groove 5.

Therefore, the present invention is designed so that whether the roof 7 of the aquarium is tapered or flat, the holder A having the same shape can be used for both cases. The first annular groove 4 and the second annular groove 5 can effectively prevent deformation and sink marks of the seat part 1b when the seat part 1a and the seat part 1b are integrally molded from a synthetic resin material. It is.

<Effects of the invention> Since the present invention is constructed as described above, it has the following advantages.

1 A container body made of synthetic resin material, which is integrally molded with a cylindrical container and a flange-shaped seat at its upper end opening, and a truncated conical container whose bottom opening corresponds to the outer periphery of the seat of this container. It consists of a cap of
The second annular groove recessed in the seat is provided with an appropriate number of through holes at its bottom that function as drainage holes as well as bolt insertion holes, and a permanent drainage hole at its side. Since we have drilled an appropriate number of functioning holes, whether the roof of the aquarium to which the retainer is attached is tapered or flat, the same shaped retainer can be used for both. There is no need to prepare different types of caps and their mounting members, and moreover, rainwater etc. that have entered through the cord hole can be discharged to the outside through the through hole.

2. The second annular groove, which is recessed in the upper surface of the seat directly above the joint between the container barrel and the seat, is provided so that its bottom thickness is approximately the same as the thickness of the container barrel, so it can be integrally molded with synthetic resin. The first annular groove can prevent deformation of the seat, sink marks, etc. that sometimes occur due to the difference in wall thickness between the barrel and the seat, and the bottom can be formed with high dimensional accuracy. Therefore, the floatless switch can be accurately screwed and mounted, and the cap can be fitted onto the outer periphery of the floatless switch with high precision to ensure reliable mounting.

3. The holder consists of a container body that is integrally equipped with a cylindrical container and a flange-shaped seat at its upper opening, and a cap whose bottom opening corresponds to the outer periphery of the seat of the container. This eliminates the need for the conventional troublesome work of gluing the seat to the top opening of the vessel or attaching a mounting member for attaching the cap to the roof of the aquarium.
The retainer can be easily attached to the roof of the aquarium.

Thus, the intended purpose can be achieved.
