Description

[Detailed description of the invention] The present invention is a water lock in which a seal plug attached to the lower end of an operating rod is removably fitted between a water inlet and a drain port formed on both sides of the lower part of the water lock, especially the water lock. The invention relates to the improvement of a seal plug, that is, a number of ridges running vertically are continuously formed on the circumferential wall surface of the seal plug to form uneven stripes in the circumferential direction, and the ridges are formed on the upper end of the circumferential wall surface of the seal plug. The purpose of this is to form a partition wall having the same height as the sealing part, and to improve the ease of attaching and detaching the seal plug and its watertightness.

This type of water stopper generally has a smooth surface, so it requires a relatively large amount of force to attach and detach, and this is done through a long operating rod, making the operation extremely complicated. It became.

The present invention has been devised in view of the above, and an embodiment of the present invention shown in the drawings will be described below. In the figure, 1 is a cylindrical water lock body, and 2 and 3 are the water lock body
A cylindrical water inlet and a drain are formed on both sides of the lower part of the water lock, 4 is an operating rod provided substantially in the direction of the solid axis of the lock body 1, and 5 is a seal plug attached to the lower end of the operating rod 4. It is used for blocking the water inlet 2 and the drain port 4, and 6 and 7 are peaks and valleys that run vertically connected to the peripheral wall surface of the seal plug 5, The seal plug 5 is formed so that the circumferential direction is uneven, and the seal plug 5 has an uneven shape.
is a partition wall formed in the valley part 7 at the upper end of the seal plug 5 so as to have the same height as the peak part 6, and it is preferable to use a fin-shaped partition wall.

In addition, the seal plug 5 is preferably of a bullet-like structure for better fitability, and in this case, the bottom of the water lock body 1 also fits into the seal plug 5.
A spherical recess is formed to fit into the recess.

Further, the height from the bottom of the valley 7 to the top of the peak 6 is preferably about 3 to 6rIrIIt, and the angle of the peak 6 and peak 7 is preferably about 60 degrees.

As is clear from the above, the water lock having the above structure has a water inlet 2 and a drain port 3 formed on both sides of the lower part of the water lock main body 1.
In between, a seal plug 5 attached to the lower end of the operating rod 4 is removably fitted. The partition wall 8 is formed to have an uneven circumferential direction, and a partition wall 8 having the same height as the peak portion 6 is formed in the valley portion 7 at the upper end.
When fitting the seal plug 5 between the water inlet 2 and the drain port 3, the contact area between the two becomes extremely small, so frictional resistance is significantly reduced, and the seal plug is operated via a relatively longer operating rod 5. 5 is easy to attach and detach, and furthermore, since the partition wall 8 is formed in the trough 7 at the upper end of the seal plug 5, watertightness can be maintained without causing an extreme increase in frictional resistance.

As described above, the water lock of the present invention can improve the ease of attaching and removing the seal and the watertightness, and has an extremely large practical effect.
