Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a discharge mechanism for a tank that stores liquid.

[Conventional technology]

The conventional liquid discharge mechanism is to create a through hole at the bottom of the tank that stores the liquid, pass a pipe, etc. through this through hole, connect a valve, etc. to the pipe, etc. that comes out of the tank, and open it. liquid was being discharged (for example, Japanese Patent Application Laid-Open No. 108952/1983,
No. 158968, No. 153427, No. 153427, No. 153427, No. 153427, No. 153427.
No. 147377, Utility Model Publication No. 58-94954).

In addition, a socket was provided in the through hole, and a blind plug was inserted into this socket from inside the tank to prevent liquid from flowing out, and when liquid leaked out, the blind plug was pulled out from inside the tank by some means. (For example, Utility Model No. 51-38214, Utility Model No. 56-40942,
No. 51-36424, Utility Model No. 51-92958).

[Problems to be solved by the invention] As mentioned above, in the case of a conventional discharge mechanism equipped with a valve, etc., the opening/closing mechanism of the valve etc. is complicated, so the number of parts is large, the cost is high, and the valve mechanism is Since the device itself takes up a lot of space, there is a problem that it is not suitable for installation in a narrow space. In addition, since valves and other opening/closing valves are visible from the outside, there is a possibility that they may be operated by mistake or mischief (for example, Utility Model Publication No. 158968/1983), and countermeasures must be taken to prevent this.

On the other hand, in the case of a discharge mechanism that plugs a blind plug from the inside of a liquid storage tank, you may have to look into the tank or grope to find the blind plug and pull it out, which can cause injury to your hands, and there is a certain amount of space above the tank. Since this is necessary, installation locations are limited, and if the tank is installed at a high position, there are problems such as difficulty in draining the tank.

Therefore, the present invention solves the above-mentioned conventional problems.By simplifying the discharge mechanism, the area occupied by the discharge mechanism is reduced, and costs are reduced by reducing the number of parts. To provide a discharge mechanism that allows easy liquid discharge work and is difficult to operate by mistake or mischief.

[Means for solving problems]

As a means for solving the above problems, the present invention, as shown in FIG. An inner stopper 15 that can enter and exit the tank 12 through the inner stopper 15;
The structure is characterized in that a rod-like object 16 is connected to the tank 12 from the outside to allow the inner stopper 15 to be taken in and taken out, and can be detached from the inner stopper 15 at times other than when the inner stopper 15 is being taken in and out.

[Effect]

In the discharge mechanism of the present invention, a cylindrical socket part 13 is provided below the tank 12 that stores the liquid 11, and an inner stopper 15 that can go in and out of the tank 12 is provided in the cylinder of the socket part 13. The existence of the ejection mechanism is not noticeable, and the mechanism can be made difficult to be operated by mistake or mischief. The mechanism itself can be simplified because the liquid is discharged by inserting and removing the inner stopper from inside the tank. Furthermore, by providing a rod-shaped object 16 that is connected to the inner stopper 15 from the outside of the tank 12 to allow the inner stopper 15 to be taken in and taken out, and that can be detached from the inner stopper except when the inner stopper is being taken in and out.
The discharge mechanism only occupies an area as large as a socket except when discharging liquid, and since the liquid cannot be discharged without using a special rod-shaped object 16, it is possible to prevent operations by mistake or mischief.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing an ejection mechanism according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram of the mounting position of the ejection mechanism according to the embodiment. In the figure, 11 is the liquid, 12 is the tank, 13 is the socket, 14 is the seal member, 15
1 is an inner stopper, and 16 is a rod-shaped object.

This example was implemented as a discharge mechanism for a water storage tank.

As shown in FIG. 1, a socket 13 is located at the bottom of a tank 12 that stores liquid (water in this case) 11.
Open a hole large enough to insert the socket part 13.
is inserted from the inside of the tank 12 (see the illustration of the mounting position of the ejection mechanism in FIG. 2). In order to prevent water from leaking between the socket part 13 and the tank 12, a ring-shaped rubber gasket 17 is inserted between the socket part 13 and the tank 12. Then, insert the nut 18 into the socket part 13 from the outside of the tank 12.
Tighten the tank 12 by using the screws to securely fix the socket part 13 to the tank 12.

Next, a sealing member 14 made of rubber called a bushing is inserted into the cylinder of the socket portion 13 from the inside of the tank 12. Then, an inner stopper 15 molded from resin that can go in and out of the tank 12 is inserted through this seal member 14 to serve as a water stopper. As shown in FIG. 1, the inner plug 15 has a hollow structure, and a female thread 20 is cut inside the hollow portion 19. This female screw 20 corresponds to the male screw 22 of the tip 21 of the rod-like object 16 that connects the inner stopper 15 to the tank 12 from outside.

When draining the water in the tank using the discharge mechanism with such a configuration, after inserting the male screw 22 of the rod-shaped object 16 into the female screw 20 of the inner stopper 15 in the direction of arrow A,
Turn it in the direction of arrow B to securely attach it, and then attach the rod-shaped object 1 again.
6 in the direction of arrow A, the inner stopper 15
into the tank 12. As a result, the water in the tank 12 is discharged from the socket portion 13.

After draining the water, if you want to close the stopper again and store water in the tank 12, perform the procedure in reverse order. That is, after pulling the rod-shaped object 16 in the direction opposite to arrow A and storing the inner stopper 15 in its original position, the rod-shaped object 16 is pulled in the direction opposite to arrow A.
Loosen the screw by turning it in the opposite direction and remove it to finish the work.

In addition, the inner plug 15 and the bush of the sealing member 14 may be integrated to be inserted and removed.
Alternatively, the bush may be fixed to the socket portion 13 so that only the inner stopper 15 can go in and out.

By making the length ₂ of the rod-shaped object 16 sufficiently longer than the length ₁ of the socket portion 13, the inner plug 1
5 becomes easier to push up. and socket part 1
By making the length ₁ of 3 longer, the inserted finger will not reach the inner stopper 15, thereby preventing mischief.

In this embodiment, a simple and reliable screw means is used as a means for fixing and detaching the inner stopper 15 and the rod-shaped object 16, but other fixing and detaching means may be used.

[Effect of idea]

As explained above, by simplifying the discharge mechanism of the tank that stores liquid of the present invention, it is possible to reduce the area occupied by the discharge mechanism, reduce the number of parts, and reduce costs. As a result, the liquid can be discharged easily from outside the tank, and the discharge mechanism is difficult to manipulate by mistake or mischief.
