[0003] When using a circuit board, it needs to be used in different scenarios, including when it needs to be used on both sides. However, we consider that traditional circuit boards are single-sided circuit structures, which greatly reduces the convenience of using the circuit board, making it inconvenient to use the circuit board flexibly, which is extremely inconvenient. Therefore, a circuit board with a folding function is urgently needed to solve the above problem. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A circuit board with a folding function comprises a first circuit board, a second circuit board is arranged on one side of the first circuit board, and the first circuit board and the second circuit board are fixedly connected via a folding belt, a connecting plate is fixedly connected to one side of the bottom of the first circuit board, and a limiting plate is fixedly connected to one side of the bottom of the second circuit board, and a limiting groove for cooperating with the connecting plate is provided at the bottom of the limiting plate, plug rods are provided on both sides of the limiting plate, and slots for cooperating with the plug rods are provided on one side of the limiting plate and one side of the connecting plate.

[0007] Preferably, the two insertion rods are sleeved with tension springs, and one end of the two insertion rods is elastically connected to one side of the limiting plate through the tension springs.

[0008] Preferably, two magnetic attraction plates are fixedly connected to one side of the bottom of the first circuit board, and a metal plate used in conjunction with the magnetic attraction plates is fixedly connected to one side of the bottom of the second circuit board.

When the circuit board needs to be used on both sides, the first circuit board and the second circuit board are folded by using a folding belt, and two insertion rods are pulled out at the same time. When the connecting plate is placed in the limiting groove, the insertion rod is released, and the elastic effect is utilized to plug into the slot on the connecting plate to limit the connection between the first circuit board and the second circuit board. Compared with the circuit boards in the prior art that are all single-sided circuit structures, the convenience of using the circuit boards is greatly reduced, and thus the problem of inconvenience in the flexible use of the circuit boards is solved. The method proposed in the utility model folds the first circuit board and the second circuit board by using a folding belt, and then plugs into the slot by using the insertion rod to limit the connection between the first circuit board and the second circuit board, thereby achieving the effect of using the circuit board on both sides.

Specifically, the first circuit board 1 and the second circuit board 10 are folded by the folding belt 2, and then the plug rod 5 is plugged into the slot 11 to limit the connection between the first circuit board 1 and the second circuit board 10, thereby achieving the effect of double-sided use of the circuit board.

[0023] This program has the following working process:

[0024] When the circuit board with a folding function of the utility model is used, the circuit board is first placed in a desired position. When the circuit board needs to be used on both sides, the first circuit board 1 and the second circuit board 10 are folded by using a folding belt 2, and the two insertion rods 5 are pulled out at the same time. When the connecting plate 3 is placed in the limiting groove 8, the insertion rods 5 are released and can be plugged into the slots 11 on the connecting plate 3 by utilizing the elastic effect, so as to limit the connection between the first circuit board 1 and the second circuit board 10.

[0025] According to the above working process, we can know that:

[0026] The first circuit board 1 and the second circuit board 10 are folded by the folding belt 2, and then the insertion rod 5 is plugged into the slot 11 to limit the connection between the first circuit board 1 and the second circuit board 10, thereby achieving the effect of double-sided use of the circuit board.

[0027] Furthermore, the two insertion rods 5 are both sleeved with a tension spring 6, and one end of the two insertion rods 5 is elastically connected to one side of the limit plate 4 through the tension spring 6. Specifically, the tension spring 6 can be used to make the insertion rod 5 have a certain extrusion force.

[0028] Furthermore, two magnetic plates 7 are fixedly connected to one side of the bottom of the first circuit board 1, and a metal plate 9 used in conjunction with the magnetic plates 7 is fixedly connected to one side of the bottom of the second circuit board 10. Specifically, the magnetic plates 7 and the metal plates 9 are used in conjunction with each other to strengthen the stability between the first circuit board 1 and the second circuit board 10.

[0029] Furthermore, the first circuit board 1 and the second circuit board 10 are symmetrically distributed along the center of the folding strip 2 .

[0030] Furthermore, the two insertion rods 5 are symmetrically distributed along the center of the limiting plate 4 .

[0031] Furthermore, the connections between the two insertion rods 5 and the limiting plate 4 are all sliding connections.

[0032] In summary: the use of the tension spring 6 can make the insertion rod 5 have a certain extrusion force, and the cooperation between the magnetic attraction plate 7 and the metal plate 9 can further strengthen the stability between the first circuit board 1 and the second circuit board 10.
