The utility model has the beneficial effects that: the circuit board mounting structure in the prior art does not set the circuit board on the side wall and does not set the circuit board close to the side wall, because the side of the circuit board close to the side wall is inconvenient to be connected through screws.
Compared with the prior art, in the case structure convenient for disassembling and assembling the circuit boards, the first circuit board 1 is arranged on the side wall, so that the situation that the circuit boards are arranged on the bottom plate 31 and devices in the body 3 are too crowded is avoided.
The second circuit board 2 is arranged close to the side wall plate 32, so that more available space is left on the bottom plate 31;
the boss 321 and the first screw 4 are provided such that the first screw 4 penetrates the bottom plate 31 from outside the body 3 to abut the second circuit board 2 on the boss 321, and fixing the second circuit board 2 in this manner avoids the side wall plate 32 or the device on the side wall plate 32 blocking the path for a worker to screw the first screw 4 using a screwdriver.
The first circuit board 1 is arranged on the side wall plate 32 and the second circuit board 2 is close to the side wall plate 32 and is arranged in a space which is reserved on the bottom plate 31, so that a worker can normally use the second screw 5 to fix one end of the second circuit board 2 away from the side wall plate 32, which can not cause too crowding of devices, and the problem that the screwdriver is inconvenient to contact with the second screw 5.
Therefore, the chassis structure convenient for disassembling and assembling the circuit boards, provided by the utility model, avoids overcrowding devices in the chassis structure convenient for disassembling and assembling the circuit boards caused by the arrangement of a plurality of circuit boards, and solves the problem that a screwdriver is inconvenient to contact with a screw for fixing the circuit boards when the circuit boards are disassembled and assembled.
