Detailed implementation manners

[0030] Please refer to Figures 1-9 , the present invention provides the following technical solutions:

[0031] Embodiment 1

[0032] In order to fully protect the multi-layer PCB circuit board body 11, reference can be made to the attached Figure 1 - attached Figure 8, including a protective plate 1. Inside the protective plate 1, multiple layers of PCB circuit board bodies 11 are installed. At one side position on the top of the multiple layers of PCB circuit board bodies 11, a connector 2 is connected. At one end of the connector 2 arranged outside the protective plate 1, several groups of pins 3 are welded; on the outer surface position of the protective plate 1, several heat dissipation openings 4 are opened. On both the left and right sides of the protective plate 1, anti-collision strips 5 are arranged. In the middle position on the side of the anti-collision strip 5 close to the protective plate 1, a moving block 6 is fixed. The moving block 6 is slidably arranged inside the protective plate 1. At one end position of the moving block 6 arranged inside the protective plate 1, a buffer mechanism is arranged. The second connecting shaft 9 included in the buffer mechanism is arranged outside the corner block 10; the corner block 10 is arranged in a "7" shape, and the inner side of the corner block 10 is installed at the corner position of the multiple layers of PCB circuit board bodies 11. A sliding groove 101 is also opened at the outer side position of the corner block 10. On the side walls of the front and rear two groups of corner blocks 10, connection plates 17 are fixed. The connection plates 17 are symmetrically distributed in two groups with respect to the horizontal center line of the multiple layers of PCB circuit board bodies 11; the buffer mechanism includes first connecting shafts 7 installed at both ends on one side of the moving block 6. On the outer side of the first connecting shaft 7, a connecting rod 8 is rotatably connected. At the other end of the connecting rod 8, it is rotatably arranged outside the second connecting shaft 9. The outer side of the second connecting shaft 9 is slidably arranged in the sliding groove 101 opened on the surface of the corner block 10; there are two groups between the second connecting shaft 9 and the inside of the sliding groove 101 through the connecting rod 8. The buffer mechanism is symmetrically distributed in two groups with respect to the vertical and horizontal center lines of the multiple layers of PCB circuit board bodies 11; the guiding mechanism includes a moving cylinder 12 arranged at the outer side position of the moving block 6. The outer side of the moving cylinder 12 is slidably arranged inside a fixed cylinder 13. Inside the fixed cylinder 13, a piston disc 14 is also fitted. The outer end of the piston disc 14 is fixed at the end of a guiding rod 15. The rear end of the guiding rod 15 is fixed inside the moving cylinder 12. The outer side of the guiding rod 15 is fixed to the outer side of the end of the fixed cylinder 13 through a return spring 16. The outer end of the fixed cylinder 13 is fixed at the surface position of the connection plate 17. On the side of the connection plate 17 close to the multiple layers of PCB circuit board bodies 11, several air jet openings 18 are opened. The outside of the air jet openings 18 corresponds to the gaps between the multiple layers of PCB circuit board bodies 11; the moving cylinder 12, the fixed cylinder 13, and the guiding rod 15 are coaxially arranged, and the guiding rod 15 forms a sliding structure through the moving cylinder 12 and the inside of the fixed cylinder 13; the outside of the fixed cylinder 13 is connected and communicated with the inside of the connection plate 17 and the air jet openings 18. A pressure nozzle is arranged inside the air jet openings 18, and a one-way intake valve is arranged at the outer side position of the fixed cylinder 13.

[0033] First, when using the multi-layer PCB circuit board body 11, electrical connection is achieved through the cooperation of the connector 2 and the pins 3 provided on the outer side of the protection board 1, and it can be used. When the anti-collision strip 5 is collided, during the movement of the anti-collision strip 5, it can drive the moving block 6 to move, so that the first connecting shaft 7 fixed at both ends of the moving block 6 moves. Since the first connecting shaft 7 is rotatably connected to the connecting rod 8, and the other end of the connecting rod 8 is rotatably arranged outside the second connecting shaft 9, the outer side of the second connecting shaft 9 can stably slide in the chute 101 opened inside the corner block 10. At this time, when the anti-collision strip 5 is impacted, the purpose of buffering can be achieved, thereby achieving the purpose of protecting the multi-layer PCB circuit board body 11; when the impact force is too large and may cause damage to the multi-layer PCB circuit board body 11, the moving block 6 will also drive the guiding mechanism to operate when moving. When the moving block 6 drives the moving cylinder 12 to move, the guiding rod 15 provided in the middle of the moving cylinder 12 can stably slide through the piston disc 14 inside the fixed cylinder 13. At this time, the gas inside the fixed cylinder 13 can be jet-treated through the setting of the connecting plate 17 and the jet port 18, and a pressure nozzle is arranged inside the jet port 18, which can perform sufficient outgassing and heat dissipation treatment between the board parts of the multi-layer PCB circuit board body 11. In addition, a one-way intake valve is arranged inside the fixed cylinder 13, which can continuously transport the gas for convenient subsequent continuous use.

[0034] Embodiment 2

[0035] In order to solve the problem that when the multi-layer PCB circuit board on the current market collides, it may cause a short circuit between the multi-layer PCB circuit boards, and the accumulation of heat may cause the PCB circuit board to catch fire. Please refer to the attached Figure 3 - Attached Figure 9; An elastic airbag 20 is also fixed at the end position of the moving block 6. An air delivery pipe 21 is connected to the outer side of the elastic airbag 20. The outer end of the air delivery pipe 21 is connected to one side of the heat exhaust mechanism. The setting of the heat exhaust mechanism can achieve rapid heat removal treatment between the multilayer PCB circuit board bodies 11; the heat exhaust mechanism includes the air delivery pipe 21 connected to one side of the elastic airbag 20. The outer side of the air delivery pipe 21 extends into the interior of the multilayer PCB circuit board body 11, and the air delivery pipe 21 is connected to the middle position of the vertical rod 22. A connecting spring 23 is arranged inside the vertical rod 22. The upper and lower ends of the connecting spring 23 are respectively connected to one end of two moving piston blocks 24. A conical fitting block 25 is installed inside one end of the two moving piston blocks 24. The end position of the conical fitting block 25 extending into the moving piston block 24 is connected to the moving piston block 24 through a matching elastic sheet 26. Top blocks 28 are also fixed on the outer sides of the upper and lower ends of the moving piston block 24. The outer sides of the top blocks 28 are attached to the outer side of the plate of the multilayer PCB circuit board body 11. A number of air outlet openings 27 are also formed at a position on the side of the moving piston block 24 close to the top block 28; the air outlet openings 27 are arranged at equal angles with respect to the center position of the moving piston block 24, and the direction of the air outlet openings 27 faces the outer side of the plate of the multilayer PCB circuit board body 11; the outer side of the conical fitting block 25 is attached to the outer side of the moving piston block 24. The elastic force of the matching elastic sheet 26 is greater than the elastic force of the connecting spring 23. The conical fitting block 25 and the interior of the moving piston block 24 form an elastic sliding structure through the matching elastic sheet 26.

[0036] When one side of the moving block 6 presses one side of the elastic airbag 20, the gas inside the elastic airbag 20 can be delivered into the interior of the air delivery pipe 21, so that the gas is delivered into the interior of the vertical rod 22, and the two moving piston blocks 24 arranged inside the vertical rod 22 move relatively through the connecting spring 23, so that the top blocks 28 arranged at the outer side position of the moving piston block 24 are attached to the outer side of the plate of the multilayer PCB circuit board body 11. Through the extrusion of the top blocks 28, the plate of the multilayer PCB circuit board body 11 is warped to a certain extent. At this time, the gap between the plates of the multilayer PCB circuit board body 11 can be ensured. In addition, when the gas inside the vertical rod 22 continues to increase, the gas can act on the outer side of the conical fitting block 25, so that the conical fitting block 25 can stably slide inside the moving piston block 24 through the matching elastic sheet 26. At this time, the gas is delivered to the outer side of the plate of the multilayer PCB circuit board body 11 through the air outlet openings 27, so that the heat inside the multilayer PCB circuit board body 11 is quickly discharged through the heat exhaust opening 19 and the heat dissipation opening 4, avoiding heat accumulation during the process of the multilayer PCB circuit board body 11 being impacted and causing a short circuit, and then causing a fire phenomenon.
