0 is fitted with the loosening prevention spacer 1 in the square hole 3, and the loosening prevention spacer 1 and the locking metal plate 6 are tightened and fixed to the locking shaft 9 by the bolt 4 screwed into the screw hole 11 of the square shaft portion 10, The bent upright piece 2 provided on the loosening prevention spacer 1 is brought into contact with the side surface of the head 5 of the bolt 4.

Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-loosening spacer used for a bolt for tightening and fixing a stopper plate to a locking shaft of a lock handle device.

[0002]

2. Description of the Related Art In a conventional lock handle device, a stopper plate fitted on a locking shaft is fastened and fixed to the locking shaft with a bolt, but the bolt gradually loosens during long-term use, and the bolt is locked to the locking shaft. Sometimes, the stopper plate slipped out of the screw hole and slipped against the lock shaft.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a loosening prevention spacer that can accurately prevent loosening of a fastening plate fixing bolt.

[0004]

Means for Solving the Problems In the present invention, reference will be made to the reference numerals in the accompanying drawings. The loosening prevention spacer 1 and the locking metal plate 6 are fastened and fixed to the locking shaft 9 by the bolts 4 fitted in the holes 3 and screwed into the screw holes 11 of the square shaft portion 10, and the loosening prevention spacer 1 The bent upright piece 2 provided on the above is brought into contact with the side surface of the head 5 of the bolt 4.

The loosening prevention spacer 1 is fitted into the square shaft portion 10 of the locking shaft 9 in the square hole 3 to prevent rotation of the loosening prevention spacer 1 with respect to the locking shaft 9, while the loosening prevention spacer is provided. When the bent upright piece 2 of No. 1 abuts on the side surface of the head 5 of the bolt 4, the rotation of the bolt 4 with respect to the anti-loosening spacer 1 is blocked, so that the slack of the bolt 4 is blocked. .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, the bearing tubular portion 16 of the fixed main body 15 of the lock handle device 7 is inserted into the mounting hole 13 of the door 12 and fitted into the outer peripheral thread portion of the bearing tubular portion 16. The fixed body 15 is fixed to the door 12 by the nut 14. The square shaft portion 10 at the rear end of the locking shaft 9 fitted into the bearing cylinder portion 16 is projected from the bearing cylinder portion 16, and the stopper plate 6 cannot rotate relative to the square shaft portion 10 through the square hole 17. The anti-loosening spacer 1 is fitted into the square shaft portion 10 in the square hole 3 so as not to rotate relative to the square shaft portion 10.

The hexagonal bolt 4 is screwed into the screw hole 11 of the square shaft portion 10, whereby the loosening prevention spacer 1 and the locking metal plate 6 are fastened and fixed to the locking shaft 9. The hexagonal bolts 4 are prevented from rotating and loosening with respect to the locking shaft 9 by bending the bent upright pieces 2 provided on the left and right of the loosening prevention spacer 1 and contacting the flat side surfaces of the heads 5 of the bolts 4. To be done.

[0008]

As described above, in the present invention, the anti-loosening spacer 1 is fitted into the square shaft portion 10 of the locking shaft 9 in the square hole 3 so as not to rotate relative to each other, and the bent standing piece 2 of the anti-loosening spacer 1 is fitted. Since the bolt 4 is brought into contact with the side surface of the head portion 5 of the bolt 4, the bolt 4 does not rotate in the slacking direction and the stopper plate 6 does not fall off the locking shaft 9 due to vibration or the like.
