Power circuit control board fine adjustment type power box

Abstract

The invention relates to the technical field of power boxes, and discloses a power circuit control board fine adjustment type power box which comprises a power box shell, a supporting seat is fixedlyconnected to the interior of the power box shell, a placement seat is slidably connected to the inner side of the supporting seat, and a protection spring is movably connected to the interior of the placement seat. A bevel gear set is arranged in the supporting seat, a threaded column is rotatably connected to the side surface of the bevel gear set, a ratchet base is engaged with the outer surfaceof the threaded column, a lifting rod is movably connected to the outer surface of the ratchet base, a jacking base is movably connected to one end of the lifting rod, and a jacking spring is movablyconnected to the interior of the jacking base. The upper surface of the jacking base is movably connected with the protection spring. Under the action of the protection spring and the protection spring on the inner wall of the placement seat, the protection bag can bear pressing force with a certain buffering degree, the circuit board is prevented from being damaged, meanwhile, workers do not need to operate the protection bag, and certain workload is reduced.

Description

technical field [0001] The invention relates to the technical field of power boxes, and discloses a power circuit control board fine-tuning type power box. Background technique [0002] Power chassis are mostly used to load instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other items. Most of the materials are high-quality aluminum alloy profiles. Aluminum alloy profiles have firm structure, beautiful appearance, and good heat dissipation. It is an ideal box for high-end instruments and meters. The control board is also a kind of circuit board. Although its application range is not as wide as that of circuit boards, it is more intelligent and automatic than ordinary circuit boards. [0003] Now when installing the circuit board inside the power box, the staff usually fix it manually with bolts, which is not only troublesome to operate, but also requires a lot of work.
