DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage printed circuit board, a liquid crystal panel, a solar panel, a stained glass, etc., which are stored and supported between opposing movable side plates and fixed side plates. The present invention also relates to a rack for accommodating plate-like bodies such as printed circuit boards, which integrally handle a plurality of plate-like bodies such as printed circuit boards from insertion / ejection into a machine and storage to transportation.

[0002]

2. Description of the Related Art Conventionally, a printed circuit board storage rack, for example, has left and right side plates fixed to a support frame between a top plate and a bottom plate attached to a plurality of aluminum columns, and one side plate is a top plate. The other side plate is fixed to the plate and the bottom plate, and the other side plate is movable along an elongated hole provided in the left and right directions on the top plate and the bottom plate. Are provided in multiple stages, a plurality of printed circuit boards are supported between left and right side plates, and metal lock pins are provided between a top plate and a bottom plate on the front and back surfaces of the rack body.

[0003] The upper and lower ends of the movable support frame are fixed to the outside of the elongated hole with fastening members such as bolts and screws. When the support frame is slid, the fastening member is loosened and the support frame is moved along the elongated hole. After adjusting the storage width, the fastening member is tightened to position the movable side plate. Further, the one-touch locking mechanism uses gears, so that the gears are easily damaged, and the entire locking mechanism needs to be replaced frequently.

In such a configuration, when the support frame is slid, workability of fastening members such as bolts and screws is poor.
In particular, the work at the lower end could not be performed without reversing the rack.

A metal lock pin is provided between the top plate and the bottom plate on the front and rear sides of the rack main body to prevent the supported printed circuit board from falling off. A small diameter projection is provided at the lower end, and this projection is fitted and fixed in holes provided in the top plate and the bottom plate,
There is a disadvantage that the lock pin has no elasticity and is difficult to be detached.

[0006] The side plate is formed of a single plate,
If it is partially damaged, the entire side plate must be replaced.If the side plate is composed of multiple single units, only the damaged plate may be replaced, but the top plate and support frame are disassembled for replacement and replaced again. They have to be assembled and require a lot of work.

[0007]

SUMMARY OF THE INVENTION From the above points, the present invention provides:
Adjustment of the storage width of the side plate can be adjusted with one touch,
An object of the present invention is to provide a rack for storing a plate-like body such as a printed circuit board in which only a damaged side plate can be replaced or repaired when a side plate is damaged, and a lock pin can be detached with a single touch.

[0008]

In order to solve the above-mentioned problems, the present invention comprises left and right side plates fixed to a support frame between a top plate and a bottom plate attached to a plurality of columns. The side plate is fixed to the top plate and the bottom plate, and the side plate on the other side is movable along a long hole provided in the left and right direction on the top plate and the bottom plate. In a rack for accommodating a plate-like body such as a printed circuit board in which engagement grooves are provided in multiple stages and a plurality of plate-like bodies such as a printed board are supported between left and right side plates, a plurality of fixed-side and movable-side side plates are provided. , And each side plate is detachably attached to the support frame.

Further, the present invention provides a stopper in which a cap provided with a bulging portion on the side is fixed to an upper end and a lower end of a movable supporting frame, and a flange portion is formed at a base end of the bulging portion of the cap. The cam portion of the cam lever that engages with the lower surface of the bulging portion of the cap is rotatably mounted on the rod portion that penetrates from the outside of the elongated hole and that protrudes from the bulging portion. When the cam portion of the cam lever engages the lower surface of the bulging portion of the cap, the flange of the stopper presses against the edge of the long hole from the outside, and the movable support frame is fixed between the top plate and the bottom plate. It is characterized by the following.

Further, the present invention is characterized in that a lock pin made of synthetic resin is detachably provided between the top plate and the bottom plate.

According to the first aspect of the present invention, the fixed and movable side plates of the rack body are divided into a plurality of parts and are detachably attached to the support frame. Only the damaged side plate can be removed from the support frame and replaced with a new side plate.

According to a second aspect of the present invention, the cam lever is rotated, and the cam portion is engaged with the lower surface of the bulging portion of the cap fixed to the end of the support frame, whereby the stopper is attached to the shaft of the stopper. Is pulled toward the distal end of the rod portion of the stopper, and the flange portion of the stopper is pressed against the edge of the elongated hole, so that the movable-side support frame is fixed. When the support frame is slid to adjust the storage width, the cam lever is rotated, and the engagement between the cam portion and the bulge portion of the cap is released, so that the pressure contact of the flange portion of the stopper is loosened and the movable side is supported. The frame becomes slidable.

Further, in the case of the third aspect, since the lock pin is made of a synthetic resin and bends, the lock pin is easily attached and detached.
