Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a storage for organizing and storing integrated circuit boards and the like.

(Prior Art) As shown in Utility Model Registration No. 1508285, there is a known storage cabinet that prevents a shelf board on which an integrated circuit board is placed from accidentally falling in the event of an earthquake or other disaster. ing.

(Problems to be solved by the invention) As described above, a storage cabinet is known in which a shelf board on which an integrated circuit board or the like is mounted does not drop when an earthquake or other disaster occurs. However, this kind of storage is extremely inconvenient to use because it has a drawback that, when an integrated circuit board or the like is taken out of the shelf board, it sparks due to static electricity and the worker is injured unexpectedly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional drawbacks, and an object thereof is to obtain a storage cabinet in which an integrated circuit board or the like can be taken out from a shelf board very easily without being injured.

(Means for Solving the Problem) As a means for achieving this, the present invention is to insert bolts at four corners inside the storage main body so as to straddle a top plate and a bottom plate. Tighten with nuts through nuts and fix to the top plate and bottom plate respectively, attach the ground to the upper ends of the bolts, and also to each bolt, a conductive shelf with insertion grooves for integrated circuit boards on both front and back sides. Insert the through holes provided at the four corners of the plate to allow each conductive shelf to move up and down along the bolts, and insert washers and nuts into each bolt to attach each conductive shelf to its front and back. It is tightened with nuts from both sides via washers.

(Embodiment) A specific configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. (1) is the storage body, and the storage body (1)
Bolt across the top plate (2) and bottom plate (3) at the four corners inside.
(4) (4) (4) (4) is inserted and the bolts (4) (4) (4) (4)
The upper and lower ends of the are fastened with nuts (6) through the washer (5) and fixed to the top plate (2) and the bottom plate (3), respectively. Bolt (4)
(4) Of the (4) and (4), ground (7) to the upper end of one bolt (4).
And ground the other end of the ground (7) to an appropriate place. Also, in each of the above bolts (4), (4), (4), (4), at the four corners of the conductive shelf board (9), which has insertion grooves (8) for the integrated circuit board (IC board) on both front and back surfaces. Through holes provided (10) (10) (10) (1
(0), and each conductive shelf (9) can be moved up and down along the bolts (4) (4) (4) (4), and the washers (5)
Insert nuts (6) into bolts (4) (4) (4) (4) and tighten conductive shelves (9) with nuts (6) from both front and back sides via washers (5). To fix. Although not shown, the conductive shelf board (9) is provided with conductive paint layers on both front and back surfaces of a substrate made of wood, iron or the like, and an integrated circuit board (IC substrate) is provided on the paint layer portion. You may engrave the insertion groove such as. Further, in order to facilitate the attachment and detachment of the conductive shelf board (9), a notch communicating with the through hole (10) may be provided as shown by the dotted line portion in FIG.

(Effect of the Invention) As described above, the present invention has a top plate (2) and a bottom plate of the storage body (1).
Insert the conductive shelf board (9) into the bolts (4), (4), (4) and (4) that are erected and fixed over (3), and bolt both sides of the conductive shelf board (9) to the bolt ( 4) The conductive shelves (9) do not fall due to vibration such as an earthquake because they are fastened and fixed with the washer (5) and nut (6) inserted in (4) (4) (4) (4). Also, the height of the conductive shelf board (9) can be freely adjusted. Further, according to the present invention, since the shelf board on which the integrated circuit board (IC board) is placed is the conductive shelf board (9), and the ground (7) is attached to the upper end of the bolt (4), the conductive shelf is installed. When the integrated circuit board (IC substrate) placed on the board (9) is taken out, it has an excellent effect such as being free from injury due to static electricity unlike the conventional one.

Claims (1)

[Scope of utility model registration request] 1. A bolt is inserted into the four corners of the inside of the storage cabinet, straddling a top plate and a bottom plate, and the upper and lower ends of the bolt are fastened with nuts through a washer to fix them to the top plate and the bottom plate, respectively. At the same time, ground is attached to the upper end of the bolt, and through holes provided at the four corners of the conductive shelf board having insertion grooves for integrated circuit boards on both front and back sides are inserted into each of the above-mentioned bolts. A storage cabinet that allows the shelf to move up and down along the bolts, inserts washers and nuts into each bolt, and tightens each conductive shelf from both the front and back sides of the shelf with the nuts.
