Abstract

The invention discloses a gas transmission system and cushion block-including fixed leg device for PCB circuit boards. The fixed leg device is fixedly connected with a frame body (1) to fix a PCB circuit board (2) on the frame body (1); the fixed leg device comprises a fixed body (8), the bottom of which is fixedly connected with the frame body (1); the fixed body (8) comprises a bottom ledge part which comprises a ledge surface (81) for bearing the back surface of the PCB circuit board and an integrally formed vertical column (9) which is vertical to the ledge surface (81); the vertical column part (9) comprises a cylindrical root part (92) which is arranged at the bottom and integrally connected with the ledge surface (81) and is used for jointing a fixed hole on the PCB circuit board, a cylindrical top part (91) which is located at the tail end of the top, and a middle connection part which is located between the cylindrical root part (92) and the cylindrical top part (91) and is cylindrical as a whole.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a fixed column device with an air conveying system and shock absorbing pads 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...
