蓋体ロツク装置。 It is a lid locking device that locks the lid of a groove cover or manhole cover to a lid holder frame so that it cannot be removed by an unscrupulous person, and is made of a non-magnetic lid that allows magnetic force to pass through but does not become magnetized. a locking cap fitted into the cap fitting hole so as to be rotatable by engagement of a magnetic opening/closing handle;
a rotary locking means for locking the lid, which is provided below the center of the locking cap so as to rotate together with the cap, to a receiving frame lid locking portion;
The cap has a locking engagement portion that removably engages with the rotation locking fitting portion at the bottom of the cap fitting hole, and is installed in an internal position where dirt, etc. of the cap does not enter so that it can move up and down but cannot rotate. The movable lock body is equipped with a movable lock body that can be attracted by a magnet, and this movable lock body disables rotation of the cap in the normal lowering lock state in which the rotation engagement part engages with the rotation engagement part, and the cap is opened and closed with a magnet. When the handle is engaged with the cap and the cap is removed, the rotation engaging part is pulled up to the unlocked state in which the rotation engaging part is disengaged from the rotation engaging part by the attraction action of the handle magnet, and the cap can be rotated. A lid locking device characterized in that it is configured as a magnet-responsive body for an opening/closing handle with a magnet.
