Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, in particular to a novel PCB board placement rack. Background Art

[0002] PCB (Printed Circuit Board), Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. In the production process of PCB boards, it is often necessary to place PCB boards on a placement rack. The surface of PCB boards is often treated in electroplating solution, and due to its porosity, it absorbs a certain amount of solution and water. Therefore, PCB boards cannot be directly stacked when placed. It is necessary to drain any water that may be carried during the placement process. During the transportation of PCB boards, it is necessary to ensure that the placement rack can stably load the PCB boards to prevent damage during transportation.

[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN214650448U discloses a PCB board placement rack, which can improve the stability of the PCB board. According to the different sizes of PCB boards, the adjustment component adjusts the spacing to facilitate clamping the PCB board. The connecting plate is fixedly connected to the protective plate through the fixing component. The adjustment plate can clamp PCB boards of different sizes due to the different positions of the fixing component.

[0004] However, when the device is used, the PCB board is first inserted into the first slot, and then the PCB board is pushed to move by the adjusting plate, so that the two sides of the PCB board are respectively inserted into the second slot and the third slot, thereby completing the fixation of the PCB board. However, before the position of the PCB board is adjusted by the adjusting plate, the PCB board is only fixed by the first slot, and the fixing effect is limited. In addition, it is difficult to push multiple groups of PCB boards to move at the same time by the adjusting plate. Finally, it needs to be fixed by tightening the bolts, which is cumbersome and cannot meet the use requirements well. Utility Model Content

[0026] As a further solution, the locking assembly includes a locking rod 24 that is slidably inserted into the position of the positioning slider 22 on both sides of the positioning plate 21, a locking plug block 241 is fixed to the lower end of the locking rod 24, and a plurality of locking grooves 121 are provided at the position corresponding to the locking plug block 241 at the lower end of the reinforcing rod 12. A locking end cover 244 is also fixed to the upper end of the locking rod 24, and a locking spring 243 is also mounted on the upper half of the locking rod 24, and the two ends of the locking spring 243 are respectively abutted and connected with the locking end cover 244 and the corresponding side of the reinforcing rod 12.
