Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board that is easy to store. Background Technology

[0002] A circuit board, also known as a printed circuit board or printed circuit board, makes circuits miniaturized and more intuitive. It plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. After the circuit boards are produced, they need to be stacked and stored for transportation.

[0003] Common circuit boards only include the circuit board itself, which can make the circuit miniaturized and intuitive, but lacks storage function. It cannot guarantee that the circuit boards will not be damaged by friction when stacked. When stacking circuit boards, the upper and lower circuit boards may come into contact with each other. This contact can cause friction between multiple circuit boards due to shaking during transportation, resulting in damage to the circuit board itself or the circuits on the circuit board, affecting the quality of the circuit board.

[0004] Therefore, in view of the problem that the above-mentioned circuit boards lack a stacking protection mechanism when stacked and stored, and are prone to displacement friction due to direct contact between the upper and lower boards during transportation vibration, resulting in damage to the surface or circuits and affecting the stability of product quality, there is an urgent need to design a new type of circuit board that is easy to store. Utility Model Content

[0005] To overcome the common problem that circuit boards lack a stacking protection mechanism when stacked and stored, and are prone to displacement and friction due to direct contact between the upper and lower boards during transportation vibration, resulting in surface or circuit damage and affecting product quality stability.

[0006] The technical solution of this utility model is as follows: a circuit board that is easy to store, including a PCB board; it also includes a lower guard plate, a recycling trough, a rotating shaft, a support rod, a rubber block, and a limiting frame. The bottom of the PCB board is provided with a lower guard plate, and recycling troughs are symmetrically provided on the front and rear sides of the top of the lower guard plate. A rotating shaft is provided on one side inside the recycling trough, and a support rod is provided inside the recycling trough corresponding to the position of the rotating shaft. A rubber block is provided on the other side inside the recycling trough corresponding to the position of the support rod. A limiting frame is symmetrically provided on the front and rear sides of the top of the PCB board corresponding to the position of the support rod.

[0007] Preferably, the support rod at the bottom of the first circuit board is pulled downwards from inside the recycling tank. At this time, the support rod rotates around the pivot until it is in a vertical position. Then, the bottom end of the support rod at the bottom of the first circuit board is inserted into the limiting frame at the top of the second circuit board. This not only allows for the stacking and storage of printed circuit boards, but also allows them to be disassembled when needed, preventing contact between the printed circuit boards and reducing damage caused by friction. This achieves the storage function, solving the problem that common circuit boards only contain the circuit board body, which can make the circuit miniaturized and intuitive, but lacks storage function. It cannot guarantee that the circuit boards will not be damaged by friction when stacked. When stacking circuit boards, the upper and lower circuit boards may come into contact with each other. This contact can cause friction between multiple circuit boards during transportation due to shaking, resulting in damage to the circuit board itself or the circuits on the circuit board, affecting the quality of the circuit board.

[0008] Preferably, the rotating shaft is rotatably connected to the support rod, and the inner diameter of the limiting frame is larger than the outer diameter of the support rod.

[0009] Preferably, a spring is provided at the bottom of the inner part of the limiting frame, and a push plate is provided at the top of the spring.

[0010] Preferably, two upper fixing holes are provided on the front and rear sides of the top of the PCB board, corresponding to the positions of the limiting frame.

[0011] Preferably, two lower fixing holes are provided on the front and rear sides of the top of the lower guard plate, corresponding to the positions of the upper fixing holes.

[0012] Preferably, an expansion plate is provided on the top right side of the PCB board, and two upper fixing slots are symmetrically opened through the top right and rear sides of the expansion plate.

[0013] Preferably, two lower fixing slots are provided on the right and rear sides of the top of the lower guard plate, corresponding to the positions of the upper fixing slots, and several pin slots are provided on the top of the lower guard plate, corresponding to the positions of the bottom pins of the PCB board.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device removes the support rod at the bottom of the first circuit board, rotates it around the pivot to a vertical position, and embeds the bottom end of the support rod into the limiting frame at the top of the second circuit board, forming a retractable support structure. This achieves physical isolation for stacked circuit boards and avoids direct contact between printed circuit boards through a modular disassembly and assembly mechanism. During transportation and storage, the dual function of rigid support and limiting locking eliminates the risk of friction damage, completing the integrated function of immediate installation and fast disassembly as needed.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a circuit board that is easy to store, including a PCB board 1; it also includes a lower guard plate 2, a recycling groove 3, a rotating shaft 4, a support rod 5, a rubber block 6, and a limiting frame 7. The lower guard plate 2 is provided at the bottom of the PCB board 1. Recycling grooves 3 are symmetrically provided on the front and rear sides of the top of the lower guard plate 2. A rotating shaft 4 is provided on one side inside the recycling groove 3. A support rod 5 is provided inside the recycling groove 3 at the position corresponding to the rotating shaft 4. A rubber block 6 is provided on the other side inside the recycling groove 3 at the position corresponding to the support rod 5. Limiting frames 7 are symmetrically provided on the front and rear sides of the top of the PCB board 1 at the positions corresponding to the support rod 5. When the support rod 5 at the bottom of the first circuit board is pulled out downward from inside the recycling groove 3, the support rod 5 rotates around the rotating shaft 4 until the support rod 5 is vertical. In this state, the bottom end of the first circuit board bottom support rod 5 is then inserted into the limiting frame 7 at the top of the second circuit board. This not only allows for the stacking and storage of printed circuit boards, but also enables their disassembly when needed, preventing contact between printed circuit boards and reducing damage caused by friction. This achieves the storage function, solving the problem of common circuit boards that only contain the circuit board body, which can make the circuit miniaturized and intuitive, but lacks storage function. It cannot guarantee that the circuit boards will not be damaged by friction when stacked. It is easy for the upper and lower circuit boards to come into contact with each other when stacked. This contact can cause friction between multiple circuit boards due to shaking during transportation, resulting in damage to the circuit board itself or the circuits on the circuit board, affecting the quality of the circuit board.

[0023] Please see Figures 2-4 In this embodiment, two lower fixing holes 11 are provided through the front and rear sides of the top of the lower guard plate 2, corresponding to the positions of the upper fixing holes 10. An expansion plate 12 is provided on the right side of the top of the PCB board 1. Two upper fixing slots 13 are symmetrically provided through the right and rear sides of the top of the expansion plate 12. Two lower fixing slots 14 are provided through the right and rear sides of the top of the lower guard plate 2, corresponding to the positions of the upper fixing slots 13. Several pin slots 15 are provided through the top of the lower guard plate 2, corresponding to the positions of the bottom pins of the PCB board 1. When the circuit boards are transported after being stacked and stored, the circuit boards will bounce up and down due to the bumps. When the circuit board above falls from above, it will apply a certain pressure to the circuit board below through the support rod 5. At this time, the support rod 5 will press down on the push plate 9, and the spring 8 will buffer the downward pressure of the push plate 9, thereby preventing the circuit board below from cracking or breaking due to the downward pressure.

[0024] Please see Figures 1-4 In this embodiment, the rotating shaft 4 is rotatably connected to the support rod 5. The inner diameter of the limiting frame 7 is larger than the outer diameter of the support rod 5. A spring 8 is provided at the bottom of the limiting frame 7, and a push plate 9 is provided at the top of the spring 8. Two upper fixing holes 10 are opened through the front and rear sides of the top of the PCB board 1 corresponding to the positions of the limiting frame 7. The support rod 5 at the bottom of the first circuit board is pulled out from the inside of the recycling groove 3. At this time, the support rod 5 rotates around the rotating shaft 4 until the support rod 5 is in a vertical state. Then, the bottom end of the support rod 5 at the bottom of the first circuit board is inserted into the limiting frame 7 at the top of the second circuit board. This not only allows for the stacking and storage of printed circuit boards, but also allows for their disassembly when needed, preventing contact between printed circuit boards and reducing damage caused by friction. This achieves the storage function and prevents the upper and lower circuit boards from contacting each other when stacked. Such contact can cause friction between multiple circuit boards during transportation due to shaking, resulting in damage to the circuit board itself or the circuits on the circuit board, affecting the quality of the circuit board.

[0025] During operation, the support rod 5 at the bottom of the first circuit board is pulled downwards from inside the recycling tank 3. At this time, the support rod 5 rotates around the pivot 4 until it is in a vertical position. Then, the bottom end of the support rod 5 at the bottom of the first circuit board is inserted into the limiting frame 7 at the top of the second circuit board. This not only allows for the stacking and storage of printed circuit boards, but also enables them to be disassembled when needed, preventing contact between the printed circuit boards and reducing damage caused by friction. When the circuit boards are transported after being stacked and stored, the boards may bounce up and down due to bumps. When the upper circuit board falls from above, the support rod 5 will exert a certain pressure on the lower circuit board. At this time, the support rod 5 will press down on the push plate 9, and the spring 8 will cushion the downward pressure of the push plate 9, thereby preventing the lower circuit board from cracking or breaking due to the downward pressure, thus achieving the storage function.

[0026] Through the above steps, the support rod 5 at the bottom of the first circuit board is pulled downwards from inside the recycling tank 3. At this time, the support rod 5 rotates around the pivot 4 until the support rod 5 is in a vertical state. Then, the bottom end of the support rod 5 at the bottom of the first circuit board is inserted into the limiting frame 7 at the top of the second circuit board. This not only allows for the stacking and storage of printed circuit boards, but also allows them to be disassembled when needed, preventing contact between printed circuit boards and reducing damage caused by friction. This achieves the storage function, solving the problem that common circuit boards only contain the circuit board body, which can make the circuit miniaturized and intuitive, but lacks storage function. It cannot guarantee that the circuit boards will not be damaged by friction when stacked. It is easy for the upper and lower circuit boards to come into contact with each other when stacked. This contact can cause friction between multiple circuit boards due to shaking during transportation, resulting in damage to the circuit board itself or the circuits on the circuit board, affecting the quality of the circuit board.
