Description

Technical Field

[0001] The utility model relates to the technical field of storage, in particular to a storage rack for printed circuit boards. Background Art

[0002] Printed circuit boards (PCBs) are essential core components of modern electronic devices. They support electronic components and serve as the means for their electrical interconnection. They are found in virtually every electronic device, including electronic watches, calculators, computers, communications equipment, and military weapon systems. Any electronic component like integrated circuits requires a PCB for electrical interconnection. PCB storage requires racks.

[0003] Prior art, such as the utility model storage rack for printed circuit boards, with authorization publication number CN220945330U, utilizes a hinged plate to hold the circuit board in place. When a storage cavity is empty of circuit boards, the clamping portion of the hinged plate is positioned away from the cavity. The arc-shaped groove and the limiting rod prevent the support portion from moving away from the cavity. Once a circuit board is inserted into the cavity, the gravity of the circuit board presses down on the support portion, causing the hinged plate to rotate. The clamping portion of the hinged plate secures the circuit board, preventing the circuit board from tilting due to the cavity being wider than the circuit board, thereby preventing friction between circuit boards in adjacent storage cavities.

[0004] Currently, there is a lack of a storage rack that can facilitate the placement and removal of circuit boards when there are a large number of circuit boards, and can heat and dry the circuit boards when the air is humid. Utility Model Content

[0028] Each of the mounting strips 16 is fixedly connected to a guide rod 7, each of the guide rods 7 passes through a slider 8, and each of the sliders 8 is disposed in a corresponding vertical slot 12. By disposing the slider 8 in the vertical slot 12 and allowing the guide rod 7 to pass through the slider 8, the guide rod 7 is able to move in the height direction and the front-rear direction.

[0029] A guide rod 13 is disposed within one of the vertical slots 12 and fixedly connected to the mounting U-plate 11. A screw 14 is disposed within the other vertical slot 12 and connected to the mounting U-plate 11. The screw 14 is threadedly connected to the uppermost slider 8. The screw 14 and the guide rod 13 each pass through the corresponding slider 8. The screw 14 is used to achieve movement of the storage frame 17.

[0030] The mounting U plate 11 is fixedly connected to the reinforcing plate 3, and the reinforcing plate 3 is fixedly connected to the motor 1 through the motor bracket 2.
