Problems solved by technology

However, during maintenance, it is often necessary to process PCB boards of different sizes, and the aperture sizes of the positioning holes on the board body of PCB boards of different sizes are different, so it is difficult for the plunger to adapt to PCB boards with various aperture sizes. As a result, the device cannot effectively locate the positioning holes of different apertures, which affects the maintenance of the PCB board and has poor practical performance

Abstract

The invention relates to the technical field of a PCB fixing device, and discloses a fixing device for PCB maintenance. The fixing device comprises a table board, wherein a fixing shaft is arranged onthe table board, the fixing shaft comprises two parallel vertical rods and a width adjusting mechanism positioned between the two vertical rods, and the width adjusting mechanism comprises a plurality of sets of rhombic frames which are sequentially arranged from top to bottom; each set of rhombic frame comprises four connecting rods which are sequentially hinged to one another in an end-to-end mode, moreover, each rhombic frame comprises two sliding corners which are opposite to each other and two connecting corners which are opposite to each other, the two sliding corners are slidably connected to the two vertical rods respectively, the two proximate connecting corners between the adjacent rhombus frames are hinged to each other, the uppermost connecting corner is hinged to one of the vertical rods, a supporting rod is hinged to the bottommost connecting corner, and the supporting rod is connected with a pulling mechanism. According to the fixing device, a PCB with positioning holeswith different sizes can be positioned and fixed, so that the maintenance of the PCB is facilitated.

Description

technical field [0001] The invention relates to the technical field of fixing devices for PCB boards, in particular to a fixing device for PCB board maintenance. Background technique [0002] PCB board, that is, printed circuit board, is based on an insulating board, cut to a certain size, with at least one conductive pattern attached to it, and a board with holes, which is used to replace the chassis of the previous electronic components. And realize the interconnection between electronic components. Since such boards are made using electronic printing, they are called "printed" circuit boards. [0003] In the process of overhauling the PCB board, the PCB board needs to be fixed. The existing fixing device of the PCB usually uses the insert rod to be inserted into the positioning hole on the PCB to limit and fix the board body. However, during maintenance, it is often necessary to process PCB boards of different sizes, and the aperture sizes of the positioning holes on t...
