Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drainage device useful for various devices that require drainage, such as a cooling container for keeping fresh food and the like cool.

(Prior Art) FIGS. 4 and 5 show a conventional example of a drainage device for a cooling container.

In the figure, 1 is a drainage hole 3a provided in a floor 3 near a wall 2.
Is a drain plug that opens and closes from above and is made of a material having a sealing property such as rubber.

Reference numeral 4 denotes an opening / closing rod that opens and closes the drain plug 1, and extends in the up-down direction (opening / closing direction). It is curved.

Reference numeral 5 denotes a support tool for supporting the opening / closing rod 4, which is fixed to the wall 2 with a substantially U-shaped cross section, and fixed to one side surface of the fixing part 6 with the opening / closing rod 4 slidably in the vertical direction. It is composed of a supporting portion 7 that supports the movable portion.

A is a cooling device for the cooling container, which is installed near the drainage device.

When condensed water or the like of the cooler A accumulates on the floor 2, the opening / closing rod 4
Is lifted up to open the drainage hole 3a for draining.

(Problems to be solved by the invention) By the way, since the rubber drain plug 1 is prone to deterioration during long-term use, it needs to be replaced regularly. Further, the drain plug 1 is usually replaced by removing the opening / closing rod 4 from the support 5.

However, since obstacles such as the cooler A are arranged on the floor 3, it is extremely difficult to remove the opening / closing rod 4 arranged in the slight gap between the cooler A and the wall 2. For this reason, there has been a problem that the opening / closing rod 4 has to be detached considerably hard and the cooler A has to be detached in some cases, which requires a great deal of labor to replace the drain plug 1.

The present invention has been made in view of the above problems, and an object thereof is to easily remove the opening / closing rod even if it is arranged in a slight gap between the obstacle and the wall. It is to provide a drainage device that can be easily replaced.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a drain plug for opening and closing a drain hole provided on a floor near a wall, and a drain plug attached to one end of the drain plug. A drainage device comprising an opening / closing rod extending in the opening / closing direction of a stopper and a support member fixed to a wall and slidably supporting the opening / closing rod, the drainage device being disposed in a gap between the wall and an obstacle near the wall, The support tool is composed of a support portion that releasably supports the opening and closing rod and a release blocking portion that blocks the release, and one of the support portion and the release blocking portion is detachable at least in a direction in which no obstacle exists. There is.

(Operation) According to the drainage device of the present invention, since the opening / closing rod is released by attaching / detaching the support portion or the release prevention portion of the detachable support in the direction in which the obstacle does not exist, an obstacle is generated in the vicinity. Even if it is arranged, it does not interfere with the removal of the opening / closing rod.

(Embodiment) FIGS. 1 to 3 show an embodiment of the present invention, in which the same components as in the conventional example are designated by the same reference numerals. That is, 1 is a drain plug, 2 is a wall, 3 is a floor, 3a is a drain hole, 4 is an opening / closing rod, and A is a cooler.

In the figure, 10 is a support tool for slidably supporting the opening / closing rod 4, a support portion 11 for releasably supporting the opening / closing rod 4, a detachable release blocking portion 12 for blocking the release, and a release blocking portion. It comprises a locking portion 13 for locking 12 to the wall 2.

The support portion 11 is formed of a flat plate extending orthogonally to the wall 2, one end of which is fixed to the wall 2, and the other end of which is wound around the substantially central portion of the opening / closing rod 4 by a half turn and extends slightly toward the wall 2 side. Further, a gap is formed between the winding start portion and the opening / closing rod 4 so as to be inserted therethrough.

The release blocking portion 12 is formed by bending a flat plate and has a central portion 12
a extends perpendicularly to the wall 2, one end of which extends along the wall 2 to the opposite side of the support portion 11 and is locked to the locking portion 13.
The other end extends toward the support portion 11 side, and the support portion 1
The gap is closed by engaging with the gap portion of No. 1. Further, the release blocking portion 12 is provided at the central portion of the release blocking portion 12.
A hole 12a for inserting a finger or the like is provided so that the can be easily attached and detached.

The locking portion 13 is composed of a flat plate fixed to the wall 2, and a part of the locking portion 13 forms a cut-and-raised portion 13a with a small clearance from the wall 2, and the cut-and-raised portion 13a and the wall 2 are separated from each other. Release blocking unit 12
The end of is inserted slidably. Also, the cut-and-raised part 1
An insertion restricting portion 13b is formed below 3a, leaving a slight portion that is not cut and raised.
By locking the insertion end of the release blocker 12 to b, the release blocker 12 is prevented from falling downward.

When draining water in the drainage device configured as described above, the opening / closing rod 4 is lifted to drain the drainage hole 3a as in the conventional example.
To release. Further, when replacing the drain plug 1, first, the release blocking portion 12 is pulled out upward and removed to release the closing of the gap of the support portion 11. Subsequently, the openable and closable rod 4 which is releasable from the support portion 11 is removed, and the drain plug 1 is replaced at a place where the work is easy.

As described above, according to the drainage device of the present embodiment, the opening / closing rod 4 can be easily released by pulling out and removing the detachable release blocking portion 12 upward. Therefore, even if the drainage device is a cooler A or the like. Even if it is arranged in a slight gap between the obstacle and the wall 2, the removal work of the opening / closing rod 4 is not hindered, and thus the drain plug 1 can be replaced very easily. It is possible to significantly improve the maintainability.

In addition, although the drainage device provided in the cooling container is shown in the above embodiment, if the drainage device is arranged in a narrow place,
It goes without saying that the present invention is also effective for various devices or structures that require draining, for example, drainage devices such as freezers / refrigerators and water tanks. In addition, the support may be, of course, one in which the support part is detachably configured instead of the release blocking part, or one in which the attachment / detachment direction, the release direction of the opening / closing rod 4 and the like are appropriately changed.

(Effects of the Invention) As described above, the drainage device of the present invention may hinder the work of removing the opening / closing rod even if it is arranged in the gap between the wall and the obstacle near the wall. Since it is not provided, the drain plug can be replaced very easily, and the maintainability can be remarkably improved.
