As shown in FIG. 2, the handle main body 10 is mainly fixed and fixed to the frame 1 serving as one tightened body via the mounting base 2, and is fixed to the door 3 of the other tightened body mainly serving as the moving side. And a receiving device 4 to be used. The door 3 is rotated by a hinge (not shown) with a large radius of curvature. However, in the range shown, the door 3 is similar to a sliding operation in the direction of the arrow. And this door 3
May be urged in the opening direction (the direction of the arrow in FIG. 1) by the repulsive force of a not-shown compressed object such as dust. As shown in FIG. 1, this fastener lock device A normally has two sets of fastener lock devices A.
Are used by being connected by the connecting shaft 5 and the connecting shaft 7, but can be used alone as a fastener lock device.

The handle main body 10 of the fastener lock device A includes a mounting base 2 fixed to the frame 1.
A support bracket 6, on which the operation handle 11 is pivotally mounted.
A support shaft 12 penetrates through the holes of the support brackets 6, 6, and the base end of the operation handle 11 is pivotally attached to the support shaft 12. The operation handle 11
An engagement shaft 13 is attached to the receiving member 4 with an attachment shaft 14 at which the engagement portion 13a at the distal end is disengaged. Then, the operation handle 11 is
As shown in the figure, the forked portion 11a extends from the base end to the middle.
Is formed, and the engagement shaft 13 is formed between the two forked portions 11a.
Is configured to be able to freely rotate. Further, stoppers 6a, 6a are formed on the distal end side of the support brackets 6, 6 in order to regulate the rotation range of the operation handle 11, and the forked portion 11a of the operation handle 11 is provided on both sides of the support bracket 6, 6. The stoppers 6a are configured to hit the six stoppers 6a.

As shown in FIG. 1, when two sets of fastener lock devices A are used, the fastener lock devices A are arranged in parallel, and the respective operation handles 11, 11
Are connected by a connecting shaft 5, and the distal ends of the engaging shafts 13 are connected by a connecting shaft 7. The connecting shaft 5 is directly connected to the operating handle 11.
Is fixed by welding or the like to the tip of the joint shaft 7.
The mounting block 8 is attached to the tip of the engaging shaft 13 and the coupling shaft 7 is fixed to the mounting block 8 by welding or the like.

As shown in FIG. 2 (a), in the fastener lock device A thus configured, the engagement portion 13a of the engagement shaft 13 has the engagement recess 4a of the receiving member 4 in the lock position.
Is engaged. Next, as shown in FIG. 2B, when the operation handle 11 is rotated counterclockwise,
The engaging portion 13a at the distal end of the engaging shaft 13 moves horizontally to the left as it is, so that the engaging portion 13a is disengaged from the engaging recess 4a of the receiving member 4. Therefore, the operator rotates the coupling shaft 7 clockwise to completely remove the engagement portion 13a from the engagement position with the engagement concave portion 4a and release the door 3.

However, for example, when the storage object is compressed dust or the like, the door 3 has elasticity and the door 3 is always pressed from the inside. Therefore, when the operation handle 11 is turned counterclockwise, the door 3 is turned. Although it is opened, the engaging portion 13a is strongly pulled in the opening direction by the receiving member 4, so that the engagement between the receiving member 4 and the engaging portion 13a does not come off as shown in FIG. Then, since the door 3 is opened in this state, the engaging portion 13a engaged with the receiving member 4 is also pulled, and the operation handle 11 is forcibly rotated in the counterclockwise direction. Accordingly, the operation handle 11 rotates to a position where the operation handle 11 hits the stopper 6a.
Since the rotation is stopped by the stopper 6a, the door 3 is also temporarily stopped at a slightly opened position, thereby preventing sudden full opening. Therefore, as shown in FIG. 3 (a), once the worker slightly returns the door 3 in the closing direction, the engagement relationship between the receiving member 4 and the engagement portion 13a is released. The door 3 is released by pivoting in the rotation direction to completely disengage the engagement portion 13a from the engagement position with the engagement recess 4a.

Next, when the frame 1 and the door 3 are locked by the fastener lock device A, first, as shown in FIG. 3B, the connecting shaft 7 is turned counterclockwise to engage.
