Description

[Detailed Description of the Invention] The present invention relates to a cover for covering a hole in a plate body through which a tube is inserted, and its purpose is to prevent misalignment of a tube through which a tube is inserted through the hole. It is an object of the present invention to provide a blind lid that can sufficiently absorb water, and that can be easily attached to a bored hole and that allows a tube to be inserted into a tube insertion hole.
The gist of this is that there is a circular upper tongue piece that covers the surface of the hole made in the plate, and a lower tongue piece that is located on the back side of the hole and that clamps the plate around the periphery of the hole. A tongue piece and a ring-shaped connecting piece that is smaller in diameter than the drilled hole that connects and integrates the upper tongue piece and the lower tongue piece and that is eccentric to the center of the upper tongue piece are integrally formed of a highly flexible material. A tube insertion hole is formed in the connecting piece and eccentric to the center of the upper tongue piece, passing from above the upper tongue piece to below the lower tongue piece, and the lower tongue piece has a hole with a smaller diameter than the upper tongue piece. The hole has a slightly larger diameter and is eccentric to the center of the upper tongue piece. From the hole center of the hole to the closest point to the outer periphery of the upper tongue piece. A blind lid characterized in that the distance to the far end is set slightly longer than the diameter of the drilled hole, and a ring-shaped connecting piece with a tube insertion hole is formed so as to be movable within the drilled hole. be.

The present invention will be explained below with reference to the drawings.

Shown in FIGS. 1 to 4 is an embodiment of a blind lid 1 according to the present invention.

Reference numeral 1 denotes a circular hole drilled in the plate body 2, into which the tube 3 is inserted, but the limb tube 3 does not necessarily pass through the center of the hole 1 due to construction reasons on site 1. It is something that does not exist.

Reference numeral 5 denotes an upper tongue piece of the blind lid 4, which is made of a highly flexible disc-shaped plate made of silicone rubber, synthetic resin, or the like.

Reference numeral 6 denotes a lower tongue piece of the blind lid 4, which is made of a highly flexible disc-shaped plate made of silicone rubber, synthetic resin, or the like.

Reference numeral 7 designates a ring-shaped connecting piece that connects and integrates the upper tongue piece 5 and the lower tongue piece 6, and is provided with a tube insertion hole 8 located inside the connecting piece 7 and penetrating from the upper tongue piece 5 to the bottom of the lower tongue piece 6. The center of the tube insertion hole 8 is eccentric with respect to the center of the circular upper tongue piece 5, as shown in the figure.

As is clear from the figure, the lower tongue piece 6 has a smaller diameter than the upper tongue piece 5 and a slightly larger diameter than the drilled hole, and as is clear from the figure, the lower tongue piece 6 is a tube that is unevenly flooded with respect to the center of the upper tongue piece 5. The distance I3 from the hole center of the insertion hole 8 to the outer periphery of the upper tongue piece 5 is slightly longer than the outer periphery of the upper tongue piece 5, and the distance I3 from the hole center of the tube insertion hole 8 to the farthest point of the outer periphery of the upper tongue piece 5 is It is set slightly longer than the diameter 12.

Since the blind plate 4 has a structure similar to an upper plate, the upper tongue piece 5 and the lower tongue piece 6 are bent appropriately, the lower tongue piece 6 is pushed into the drilled hole 1, and the upper tongue piece 5 and the lower tongue piece 6 are removed. It can be attached to the drill hole 1 by sandwiching the periphery of the drill hole 1 and positioning a ring-shaped connecting piece 7 having a tube insertion hole 8 passing through the hole 1 vertically. Even after installation, the ring-shaped connecting piece I that is formed to surround the tube insertion hole 8 is much smaller than the perforated hole 1, so the connecting piece I will not be able to pierce the tube insertion hole 8 inside the perforated hole 1. As long as it does not hit the periphery of hole 1 (
In other words, it can be freely moved (over almost the entire area of the drilled hole 1).

Thus, even if the tube 8 is deviated from the center of the borehole 1 as shown in FIGS. 1 and 2, moving the blind cover 4 as shown in FIGS. The position can be moved to a position through which the tube 3 can be inserted.

Since the lower tongue piece 6 is slightly larger than the drilled hole 1, no matter how much power is applied, the upper tongue piece 5
At the same time, the portions of the periphery of the drilled hole 1 that are subject to any force are clamped, so that they will not easily come off.

As described above, the blind pad according to the present invention has an upper tongue piece, a lower tongue piece, and a connecting piece integrally formed of a highly flexible material, and the lower tongue piece has a smaller diameter than the upper tongue piece and is slightly larger than the drilled hole. diameter, so when attaching the blind cover to the drilled hole, you can easily pinch the periphery of the drilled hole with the upper tongue and lower tongue by retracting the lower tongue and inserting it through the hole. It is easy to install, and can be installed by simply inserting it from above and sandwiching the periphery of the hole, so it is especially suitable for drilling holes in the bottom plate of wash basins. There is no problem even in cases where it is difficult to work from below the bottom plate.

Also, the distance from the center of the tube insertion hole that is eccentric to the center of the upper tongue piece to the closest point on the outer periphery of the upper tongue piece is the distance from the drilling hole to the farthest point on the outer periphery of the upper tongue piece. is set to be slightly longer than the diameter of the tube insertion hole, so no matter where the tube insertion hole is moved within the hole depending on the position of the tube to be inserted, the entire periphery of the hole is covered by the upper tongue piece. It is possible to cover the tube so that the hole cannot be seen from above, and the size of the upper tongue piece can be shielded to the minimum necessary size, and in this case, the tube insertion hole can be No matter where it is located in the hole, at least a portion of the lower tongue should clamp the periphery of the drilled hole, and the blind cover should not come off and float up from the drilled hole. It is possible to hold the lower tongue piece with the minimum necessary size.
