Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening buckle device used for holding a lid tightly against a box body in a long box having a long joint between a box body and a lid.

[0002]

2. Description of the Related Art A fixed bearing portion parallel to the joint of a box body and a lid is provided on the box body side, and the fixed bearing portion supports a tip shaft portion of an operation lever, and pushes down and rotates the operation lever with respect to the box body. Or, it is mounted so that it can be flipped up and rotated, and a movable bearing portion is provided in the middle of the operation lever in parallel with the fixed bearing portion. The movable bearing portion supports the base shaft portion of the latch ring, and the latch ring is moved with respect to the operation lever. The end of the latch ring is engaged with the locking groove of the receiving part provided on the lid side, and the movable bearing part moves straight through the locking groove and the fixed bearing part. A fastening buckle is known in which the operating lever is pushed down to a position beyond a certain angle and rotated to hold the lid in a sealed state with respect to the box body by the elastic force of the latch ring.

[0003] Since the range of the tightening force of the tightening buckle is limited by itself, for example, a long box having a long joint between the box body and the lid, such as a box for storing a signal converter of an optical communication system. Then, in order to ensure the same sealed state over the entire length of the joint, it is necessary to equip a plurality of tightening buckles at regular intervals along the joint. However, when a plurality of tightening buckles are installed, the operation of engaging and disengaging the latch ring and the receiving part by pushing down or rotating the operating lever must be performed many times. The opening operation is complicated and time-consuming.

Further, with such a fastening buckle, when a large vibration shock or a foreign object comes into contact with the operation lever, the operation lever jumps up and moves in the rotating direction, and the sealed state of the lid is unintentionally released. There is a risk. To completely eliminate this danger, a lock unit that locks the operation lever to the box body in a position where the lid is sealed with respect to the box body may be provided on the operation lever. However, equipping all of the tightening buckles with a lock unit not only unnecessarily increases the overall manufacturing cost, but also locks and unlocks the lock unit when closing and opening the lid. Are added, so that these operations are further complicated.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a substantially equal sealed state along a joint between a box body and a lid, and to appropriately prevent unintentional release of the sealed state. It is an object of the present invention to provide a fastening buckle device for a long box, in which a sealing operation and an opening operation can be performed relatively easily.
