JPH07279494A - Locking spacer of bolt for fixing clamp plate - Google Patents

Abstract

PURPOSE:To obtain a locking spacer accurately locking a bolt for fixing a clamp plate. CONSTITUTION:A locking spacer 1 is fitted to the square shaft section 10 of a locking shaft 9, to which a clamp plate 6 is fitted, in a square hole 3, and the locking spacer 1 and the clamp plate 6 are clamped and fastened to the locking shaft 9 by a bolt 4 screwed to the tapped hole 11 of the square shaft section 10. A bent upstanding piece 2 formed to the locking spacer 1 is abutted against the side face of the head section 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 a slack preventive 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 by a bolt. However, the bolt gradually loosens during long-term use and the bolt is locked against the locking shaft. The stopper plate sometimes slipped out of the screw hole and slipped against the locking shaft.

[0003]

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

[0004]

The present invention will be described below with reference to the reference numerals in the accompanying drawings. In the present invention, the locking spacer 1 is angularly connected to the angular shaft portion 10 of the locking shaft 9 fitted with the locking metal plate 6. The loosening prevention spacer 1 and the stopper 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.
The bent upright piece 2 provided in the above is brought into contact with the side surface of the head 5 of the bolt 4.

[0005]

The lock spacer 1 is fitted into the square shaft portion 10 of the lock shaft 9 in the square hole 3 to prevent the lock spacer 1 from rotating with respect to the lock shaft 9, while preventing the lock spacer 1 from rotating. Bending rising piece 2 is bolt 4
Since the bolt 4 is prevented from rotating with respect to the loosening prevention spacer 1 by abutting against the side surface of the head portion 5, the loosening of the bolt 4 is prevented.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a bearing cylinder portion 16 of a fixed main body 15 of a lock handle device 7 is inserted into a mounting hole 13 of a door 12 and a nut 1 fitted in an outer peripheral thread portion of the bearing cylinder portion 16.
The fixed main body 15 is fixed to the door 12 by 4.
Angular shaft portion 1 at the rear end of the locking shaft 9 fitted into the bearing tube portion 16
0 is projected from the bearing tubular portion 16, the stopper plate 6 is fitted into the angular shaft portion 10 in the angular hole 17 so as not to rotate relative to it, and the anti-loosening spacer 1 is opposed to the angular shaft portion 10 in the angular hole 3. It is fitted so that it cannot rotate.

The hexagonal bolt 4 is screwed into the screw hole 11 of the square shaft portion 10, whereby the locking spacer 1 and the stopper plate 6 are fixedly fastened to the locking shaft 9. By bending the bent upright pieces 2 provided on the left and right of the slack prevention spacer 1 and bringing them into contact with the flat side surface of the head 5 of the bolt 4, rotation and slack of the hexagon bolt 4 with respect to the locking shaft 9 are prevented.

[0008]

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