 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate fixing device for fixing flat plates such as printed circuit boards which are arranged in parallel with each other with a space.

[0002]

[Prior art]

 A conventional parallel plate fixing device has a structure shown in FIGS. In these figures, 1 is a flat plate such as a printed circuit board which is arranged in parallel at a distance, 2 is a through hole formed in the flat plate 1, and 3 is interposed between both flat plates 1 and Cylindrical spacers that maintain the space between 4 and 4 are through holes of the spacer 3, 5 are screw holes formed at both ends of the through hole 4, and 6 are inserted into the through holes 2 of both flat plates 1 through washers 7. The set screw is screwed into the screw hole 5, and the spacer 3 maintains the distance between the flat plates 1.

[0003]

[Problems to be solved by the device]

 In the case of the above-mentioned conventional device, since the setscrews 6 are used to fix both flat plates 1, it is necessary to tighten the screws with a special tool such as a driver, and skill such as tightening torque is required, and the screw tightening work is required. There is a problem that it takes a lot of time. The present invention has been made in view of the above points, and an object of the present invention is to provide a parallel plate fixing device for easily and quickly fixing two flat plates with a space between them without requiring a special tool or skill. .

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the parallel plate fixing device of the present invention comprises flat plates arranged in parallel at intervals, spacers interposed between the flat plates, and insertion holes formed at both ends of the spacer. And locking holes formed on both sides of both ends communicating with the insertion holes, locking rods inserted into the through holes and insertion holes of the flat plate, and abutting against the flat plate formed at the base of the locking rod. The collar, the fitting hole formed on the tip side from the base of the locking rod, the cut groove that divides the tip of the locking rod into two locking pieces, and the fitting hole that fits into the fitting hole. It is provided with a fitting rod in which the outer side portion of the stop piece is locked in the locking hole.

[0005]

[Action]

 In the parallel plate fixing device of the present invention configured as described above, the spacers are interposed between the flat plates that are arranged in parallel at a distance, and the insertion holes are formed at both ends of the spacer, so that both ends of the spacer are formed. Form a locking hole on both sides of the locking hole so that it communicates with the insertion hole, insert the locking rod into the through hole and insertion hole of the flat plate, and form the collar part that abuts against the flat plate at the base of the locking rod. A fitting hole is formed from the base of the stop rod to the tip side, and a cut groove is formed at the tip of the locking rod to divide the tip into two locking pieces, and the fitting rod was fitted into the fitting hole. Simply insert the stop rod into the through hole of the flat plate and the insertion hole of the spacer, and then insert the insertion rod into the insertion hole of the locking rod.The outer part of the locking piece of the locking rod engages with the locking hole of the spacer. The two flat plates can be fixed easily and in a short time without stopping and without using special tools and skills, thus improving work efficiency.

[0006]

【Example】

 One embodiment will be described with reference to FIGS. 1 to 4. In these drawings, 8 is a spacer, 9 is an insertion hole formed at both ends of the spacer 8, 10 is a locking hole formed at both sides of the spacer 8 so as to communicate with the insertion hole 9, and 11 is The locking rod inserted into the through hole 2 and the insertion hole 9 of the flat plate 1, 12 is formed on the base portion of the locking rod 11, and the collar portion abuts on the flat plate 1, 13 is the tip side from the base portion of the locking rod 11. Fitting hole formed through the hole, 14 is a cut groove that divides the tip end of the locking rod 11 into two locking pieces 15, and 16 is a fitting rod of a nylon rivet. The thick tip of 15 spreads outward, the outer side of both locking pieces 15 locks in the locking hole 10, and unless a special jig is used, the fitting rod 16 and the locking rod 11 are There is no way out. The flat plate 1 is not limited to the pudding substrate and may be a metal plate.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the parallel plate fixing device of the present invention, a spacer 8 is interposed between flat plates 1 arranged in parallel at a distance, and insertion holes 9 are formed at both ends of the spacer 8 so that both ends of the spacer 8 are A locking hole 10 is formed on the surface so as to communicate with the insertion hole 9, a locking rod 11 is inserted into the through hole 2 and the insertion hole 9 of the flat plate 1, and a collar that abuts the flat plate 1 at the base of the locking rod 11. The portion 12 is formed, a fitting hole 13 is formed from the base of the locking rod 11 to the tip side, and a cut groove 14 for dividing the tip into two locking pieces 15 is formed at the tip of the locking rod 11. Since it was formed and the fitting rod 16 was fitted into the fitting hole 13, the locking rod 11 was inserted into the through hole 2 of the flat plate 1 and the insertion hole 9 of the spacer 8, and the fitting rod 16 was fitted into the fitting hole 13 of the locking rod 11. The outer side of the locking piece 15 of the locking rod 11 is locked in the locking hole 10 of the spacer 8 without any special tool or skill. To and can be fixed two flat plates 1 a short time, it is possible to improve work efficiency.
