[ background of the invention ]

The PCB is also called a printed circuit board, and is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. It is called a "printed" circuit board because it is made using electronic printing. PCB boards have evolved from single-layer to double-sided, multi-layer, and flexible, and still maintain their respective trends. Due to the continuous development towards high precision, high density and high reliability, the volume is continuously reduced, the cost is reduced, and the performance is improved, so that the printed board still keeps strong vitality in the development engineering of future electronic equipment. In the process of processing the PCB, the PCB needs to go through a plurality of processes such as printing, etching, drilling and the like, and the PCB needs to be stored on the fixed support in the process of transferring the next process in one process.

In the prior art, most of PCB placing racks are fixed in size. However, in the production operation, multiple batches of PCBs with different sizes are often involved, and the PCB placement rack with a fixed size cannot meet the requirement of storing different batches of PCBs with different sizes.

The utility model discloses can realize through following technical scheme:

the utility model discloses a PCB board fixed bolster, including bottom plate and bolt, be equipped with the spout on the bottom plate, the bottom plate top is equipped with two risers, the riser both sides are equipped with integrated into one piece's fixed block, be equipped with the through-hole that the bolt passed on the fixed block, the bolt passes the slider thread tightening of aforementioned through-hole and aforementioned spout below, two all be equipped with fixed slot I on the riser looks, the bottom plate up end all is fixed with the lead screw all around, the bottom plate top still is equipped with the clamp plate, be equipped with the through-hole that the lead screw passed with the corresponding position of lead screw on the aforementioned bottom plate on the clamp plate, be equipped with the nut on the lead screw of clamp plate top, be equipped with fixed slot III on the terminal surface under the clamp plate, be equipped with fixed slot II with the fixed. And (3) placing the PCB into a fixing groove II of the bottom plate, adjusting the positions of the two vertical plates, fixing the left side and the right side of the PCB, sliding the pressing plate downwards along the screw rod to be in contact with the upper end surface of the PCB, and screwing the nut to fix the pressing plate. The relative distance of the vertical plates and the height of the pressing plate are adjusted, and the fixing requirements of the PCB boards with different sizes can be met.

Preferably, the nut is a wing nut.

Preferably, the bolt is a butterfly bolt.

Preferably, a gasket is fixed on the outer periphery of the bolt above the fixing block.

Preferably, a limiting groove is formed in the bottom plate below the sliding groove, and the sliding block slides in the limiting groove.

Preferably, the fixing grooves I, II and III are all saw-toothed. The PCB is fixed through the fixing groove I, the fixing groove II and the fixing groove III of the sawtooth shape, and the fixing requirements of the PCB with different thicknesses can be met.

Compared with the prior art, the utility model has the advantages that:

1. the relative distance of the vertical plates and the height of the pressing plate are adjusted, and the fixing requirements of the PCB boards with different sizes can be met.

2. The PCB is fixed through the fixing groove I, the fixing groove II and the fixing groove III of the sawtooth shape, and the fixing requirements of the PCB with different thicknesses can be met.
