[0002] A circuit board, also known as a printed circuit board, is a provider of electrical connections for electronic components. It is generally based on an insulating board, cut into a certain size, and has at least one conductive pattern on it. It is mainly used to replace the chassis on which electronic components were previously installed and to achieve interconnection between electronic components.

[0003] At present, in the existing circuit board production line, the circuit boards need to go through multiple processes. Due to the limitation of the production workshop space, the circuit boards often need to be manually transferred to the next process after being processed in the previous process. After being transported to the next process, the circuit boards often need to be manually placed one by one on the conveying device of the circuit board production line. The transfer vehicle usually adopts the method of stacking circuit boards. In this method, during the movement of the trolley, the circuit boards rub against each other, which can easily cause wear of the circuit board coating. At the same time, the stacked trolley is unstable and easy to tip over, causing the circuit boards to collide with the side wall during transportation, which can easily cause the side wall of the circuit board to collapse. Therefore, a fixing device for the circuit board transfer vehicle is introduced. Summary of the Invention

[0029] Working principle:

[0030] When the device is in use, the user places the circuit board 106 on the inclined slide 102 and the bottom plate 103 along the guide groove 305 and presses it. At this time, the piston 308 at the bottom of the guide groove 305 where the circuit board 106 is placed is pressed into the sliding cavity 307. At this time, the gas in the sliding cavity 307 flows into the branch grooves 401 on both sides through the main gas groove 309 and is introduced into the limiting tapes 306 that are connected to each other through the branch grooves 401. At this time, the supporting air bags 402 in the limiting tapes 306 are inflated and straightened, that is, the limiting tapes 306 on both sides are unfolded, fit with the two sides of the circuit board 106, support the circuit board 106, and prevent the circuit board 106 from tipping to the sides. After the circuit board 106 is installed, The push-pull rod 105 is pressed downward to make it slide down along the card slot plate 104. At this time, the fixed block 209 fixedly connected to the push-pull rod 105 pulls the traction rope 208, that is, the extension column 205 moves right along the slide. At this time, the extension column 205 pulls the slide bar 202 to move right along the first slide groove 201. At this time, the limit plate 204 fixedly connected to the rotating shaft 203 and rotatably connected is automatically unfolded under the action of its corresponding convex action. When the push-pull rod 105 moves down to the maximum distance, the limit plate 204 is unfolded to a right angle. At this time, the limit plate 204 and the circuit board 106 contact each other. At this time, the movable limit column 304 is inserted along the positioning block 303 and the first limit hole 301, and the push-pull rod 105 can be fixed at this time.

[0031] When the user needs to access the circuit board 106, the user pulls out the movable limit column 304, pulls up the push-pull rod 105, and uses the movable limit column 304 to fix the positioning block 303 and the second limit hole 302. At this time, the fixed block 209 loses the pulling force on the traction rope 208. At this time, the slide bar 202 moves to the left under the action of the spring 206. At this time, the limit plate 204 rotating on the rotating shaft 203 is reset as the slide bar 202 moves to the right under the action of the torsion spring. At this time, the user can directly pull out the circuit board 106.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
