When the modular PCB circuit board structure is disassembled and repaired, the supporting bodies 157 are firstly pinched to move up and down to align with the corresponding PCB circuit board 20, and if one of the supporting bodies 157 is not needed, the corresponding one of the supporting bodies 157 is moved to align between two adjacent PCB circuit boards 20. The operating shaft 153 is held between and transversely applies force to drive the frame body 151 to rotate outwards by a certain angle, so that the elastic pressing block 154 is separated from the PCB 20, then the two cross bars 155 drive the two vertical bars 156 to move, the two vertical bars 156 drive the supporting bodies 157 thereon to support the corresponding PCB 20 to separate from the corresponding clamping strips 131, so that the PCB 20 is released, and then the PCB 20 can be taken out, and the PCB 20 which is not supported by the supporting bodies 157 can be pulled out by hands subsequently. Therefore, the modular PCB circuit board structure is convenient to disassemble and maintain through the operation.

Because the supporting body 157 is lifted up by a certain amount when the frame body 151 is deflected outward by a certain angle during disassembly, the length of the supporting body 157 is greater than the thickness of the PCB 20, so that the lifting is not affected much, and the supporting body 157 can still support the corresponding PCB 20. When moving the alignment of the PCB 20, the supporting body 157 may be operated so that the middle portion thereof is lower than the corresponding PCB 20. The surface of the abutting portion of the abutting body 157 is flush with the end surface of the clamping strip 131, so that the clamping strip 131 does not interfere with the abutting body 157, and the width of the PCB 20 is large, so that the abutting body 157 can abut against the side portion of the PCB 20.

For example, in order to conveniently clamp a plurality of PCB 20, L-shaped mounting beams 41 are convexly disposed at the center of the top of the clamping plate 13, the L-shaped mounting beams 41 extend toward the frame body 151, and the end of the L-shaped mounting beams 41 is provided with the strong magnetic block 42. the modular PCB structure further includes two clamping frames 40, the two clamping frames 40 are respectively mounted at opposite sides of the bottom plate 11. each clamping frame 40 includes a mounting shaft 43, an arched post 44, a torsion spring (not shown) and a penetrating post 45. the mounting shafts 43 of the two clamping frames 40 are rotatably connected to the bottom plate 11, the two mounting shafts 43 are respectively adjacent to opposite ends of one side edge of the mounting plate 135 away from the clamping plate 13, the penetrating posts 45 of the two clamping frames 40 are respectively inserted into the two bar-shaped slots 25 of the PCB 20. one end of the arched post 44 is rotatably connected to the top end of the mounting shaft 43, the torsion spring is sleeved on the arched post 44, the opposite ends of the torsion spring are respectively connected to the mounting shafts 43 and the arched posts 44, the bottom ends of the penetrating posts 45 are fixed to the bottom plate 11, the top ends of the penetrating posts 45 are aligned to the arched post 44, and the PCB 20 can be inserted into the plurality of the PCB 20.

For example, it is particularly important that, in order to facilitate the blocking of the PCB 20 during the installation and to push and pull the PCB from the locking bar 131 during the disassembly, the frame body 151 is provided with a plurality of blocking bars 1518, the blocking bars 1518 are parallel to each other, the blocking bars 1518 are respectively blocked at one end of the PCB 20 away from the locking plate 13, the thickness of each blocking bar 1518 is smaller than that of the PCB 20, and the distance between two adjacent blocking bars 1518 is 5-8 times the thickness of the PCB 20. The end walls of the plurality of PCB circuit boards 20 are stopped by the plurality of stopper bars 1518 at the time of mounting, so that the plurality of PCB circuit boards 20 are securely mounted on the plurality of chucking bars 131.

The two arched columns 44 are used for overcoming the acting force of the torsion spring to rotate under the action of external force, so that the bottom ends of the two short rod portions 443 are magnetically adsorbed on the strong magnetic block 42 to be positioned, so that the PCB 20 is separated from the clamping strip 131 towards one side of the rack body 151 (the strip-shaped groove 25 allows the PCB 20 to move towards the direction), and the PCB is rotated under the action of external force to be separated from the space between the short rod portions 443 and the penetrating columns 45, as shown in fig. 5, and then the multiple PCB 20 can be sequentially detached. When the clamping frame 40 needs to be closed, after the two arched columns 44 are pushed forcefully to separate from the strong magnet, the magnetic adsorption force disappears due to too far distance, and at the moment, the two arched columns 44 can automatically return to abut against the bottom ends of the two penetrating columns 45 under the action of the torsion spring.

For example, in order to prevent the rotation of the two clamping frames 40 when the frame body 151 is not deflected, an L-shaped rod portion 159 is protruded from one end of the cross bar 155 away from the frame body 151, an inserting post 1595 is protruded from the L-shaped rod portion 159, an inserting hole is opened on a bottom side wall of the long rod portion 442, and the inserting post 1595 is inserted into the inserting hole to stop the rotation of the long rod portion 442.
