Abstract

The invention provides a speed-variable fixing column device for a PCB. The speed-variable fixing column device is used for connecting with a frame body (1) fixedly so as to fix a PCB (2) on the frame body (1). The fixing column device comprises a fixing body (8) of which the bottom is fixedly connected with the frame body (1); the fixing body (8) comprises a bottom shoulder part and a vertical column part (9), wherein the bottom shoulder part is provided with a shoulder face (81) used for carrying the back of the PCB, and the vertical column part (9) is of a one-piece type and vertical to the shoulder face (81); the vertical column part (9) comprises a cylindrical root part (92), a cylindrical top part (91) and a middle connecting part, wherein the cylindrical root part (92) is arranged at the bottom, is connected with the shoulder face (81) into a whole and is used for connecting with a fixing hole formed in the PCB, the cylindrical top part (91) is arranged at the tail end of the top, and the middle connecting part is cylindrical generally and arranged between the cylindrical root part (92) and the cylindrical top part (91).

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a speed-adjustable fixing 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 ...
