[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board which is easy to assemble and disassemble. Background Art

[0002] Circuit boards, also known as printed circuit boards, are an integral component of electronic devices. They are substrates used to support and connect electronic components. They typically consist of a non-conductive base material and a conductive copper layer. Through specific processes, conductive lines and connection points are formed on the substrate to achieve circuit connections and signal transmission.

[0003] Existing circuit boards are generally fixed by bolts during installation. During installation and removal, multiple bolts need to be removed step by step, which makes the installation and removal process more complicated. Utility Model Content

[0005] Therefore, one purpose of the present invention is to provide a circuit board that is easy to disassemble and assemble, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides a circuit board that is easy to disassemble and assemble, including a circuit board body and a mounting base, wherein both sides of the circuit board body are fixedly connected with mounting ear plates, and the top of the mounting base is fixedly connected with two limit plates, and the interior of the mounting base and the limit plates are provided with grooves, and four moving blocks and two moving plates are slidably connected inside the grooves, and one side of the moving block is fixedly connected with a positioning rod, and one side of the mounting ear plate is provided with a positioning hole adapted to the positioning rod, and the interior of the groove is rotatably connected with a bidirectional screw screw threadedly connected to the two moving plates, and transmission rods are provided on both sides of the moving plate to drive the moving block to move. The technical effect achieved by adopting the above-mentioned scheme is: by placing the circuit board body between the two limit plates, and then rotating the bidirectional screw screw, the rotation of the bidirectional screw screw drives the moving plate threadedly connected thereto to move, and then the movement of the moving plate drives the moving block to move through the rotation of the transmission rod, so that the positioning rod is inserted into the interior of the positioning hole, thereby fixing the circuit board body on the mounting base, making installation and disassembly easier and simpler.

[0007] Preferably, one side of the limiting plate is tangent to one side of the mounting ear plate, and a hole of the same size as the positioning hole is provided on the surface of the limiting plate. The technical effect achieved by adopting the above scheme is that by placing the circuit board body between the two limiting plates, both sides of the circuit board body can be limited, thereby facilitating the subsequent insertion of the positioning rod into the interior of the positioning hole to fix the position of the circuit board body, making the operation easier and more convenient.

[0010] Preferably, from any of the above schemes, the transmission rod includes a rod body, both ends of the rod body are rotatably connected to a hinge seat, and the two hinge seats are respectively fixedly mounted on one side of the moving block and the moving plate. The technical effect achieved by adopting the above scheme is: through the cooperation between the rod body and the hinge seat, the moving plate can push the moving block to perform corresponding moving operations through the rotation of the rod body when moving, thereby enabling the circuit board body to be positioned and separated, and the operation is simple and convenient.

[0011] Preferably, any of the above schemes is provided with a through hole on one side of the mounting base, and bearings are fixedly mounted on the inner wall of the through hole and one side of the groove, and a bidirectional screw rod is interference fit in the middle of the bearing. The technical effect achieved by adopting the above scheme is that the position of the bidirectional screw rod can be positioned by the bearing, and friction can be reduced when it rotates, thereby making the rotation of the bidirectional screw rod easier and more convenient.

[0012] Preferably, one side of the through hole is provided with a receiving groove, one end of the bidirectional screw is fixedly mounted on a plate body, one side of the plate body is fixedly connected to an adjustment block, and the plate body is located inside the receiving groove.
