Abstract

The invention discloses a fixing column device used for a PCB circuit board and transmitted by a gear, which is used for fixedly connecting to a rack body (1) so as to fix a PCB circuit board on the rack body (1); the fixing column device comprises a base part and a fixing body (8) which is fixedly connected to the rack body (1); the fixing body (8) comprises a ledge part on the bottom of a ledge surface (81) for bearing the back side of the PCB circuit board and an integrated vertical column part (9) which is perpendicular to the ledge surface (81); the vertical column part (9) comprises a column-shaped root part (92) which is integratedly connected to the ledge surface (81) and connected to the fixing hole on the PCB circuit board, a cylinder-shaped top portion (91) on the rear part of the top and a middle connection part which is between the cylinder-shaped root (92) and the cylinder-shaped top (91) and is of a general cylinder shape.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a gear-driven fixed column device for PCB circuit boards. Background technique [0002] Generally speaking, the installation of the PCB circuit board in the bracket of the equipment needs to be stable and reliable. The commonly used method or method is to punch holes on the control box, first install the pad nails for fixing the circuit board, and then pad the insulating gasket to fix the circuit board on it with screws, which can also be fixed with glue. [0003] However, this installation method requires manual screw tightening, and in some occasions where space is limited or operation time is limited, this fixing method is limited. [0004] Some existing fixed installation methods also include the use of plastic fixing nails with elastic hooks. In this way, the step of manually tightening the screws can be eliminated, and the circuit board can also be fixed....
