[0057] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0058] As Figures 1 to 10 shown, this embodiment proposes a bend-resistant PCB circuit board, including: circuit board body 1, connecting block 3, connecting frame, reset bottom plate 4, reset rod 5 and positioning component. A plurality of fastening holes 2 are opened on the circuit board body 1. Two connecting blocks 3 are detachably installed at the bottom of the circuit board body 1. The connecting frame is slidably installed between the two connecting blocks 3. The reset bottom plate 4 is located below the circuit board body 1. Both sides of the connecting frame are rotatably installed with a plurality of reset rods 5 through a plurality of connecting components, and the plurality of reset rods 5 are respectively slidably matched with the reset bottom plate 4 through a plurality of connecting components. The positioning component is slidably arranged between the two connecting blocks 3, and the positioning component is used to align two of the fastening holes 2 with bolts. For the installation of the connecting block 3, holes can be opened on the circuit board body 1, and the connecting block 3 can be fixed to the lower side of the circuit board body 1 by threaded connection.

[0059] Specifically, the connecting frame includes: fixed plate 6, support tube 7 and support block 8. Two fixed plates 6 are slidably arranged between the two connecting blocks 3. A support tube 7 is fixedly installed between the two fixed plates 6. A plurality of support blocks 8 are fixedly sleeved on the support tube 7. Among them, the fixed plate 6 can be fixed between the two connecting blocks 3 by a plug pin 14.

[0060] Correspondingly, the connecting component includes: rotating base one 9 and rotating base two 10. Rotating base one 9 is fixedly installed on the support block 8. One end of the reset rod 5 is rotatably matched with rotating base one 9. Rotating base two 10 is slidably arranged on the reset bottom plate 4 through a reset component. The other end of the reset rod 5 is rotatably matched with rotating base two 10. Among them, the reset rod 5 is in an inclined state between rotating base one 9 and rotating base two 10.

[0061] When the circuit board body 1 is subjected to a downward pressing force, the support tube 7 will also be subjected to a downward pressing force, thereby pressing the reset rod 5, causing the reset rod 5 and the first slider 11 to slide on the opening 12. When the first slider 11 slides in the opening 12, both ends of the reset rod 5 rotate on the first rotating base 9 and the second rotating base 10 respectively, and the reset spring 13 is pushed by the first slider 11. The elastic force of the reset spring 13 greatly offsets the downward pressing force on the circuit board body 1. And after the installation of the circuit board body 1 is completed, the first slider 11 is pushed back by the reset spring 13. As the first slider 11 is reset, it will push the reset rod 5 to move upward. Because the reset rod 5 is in an inclined state, the reset rod 5 will push the concave part of the circuit board body 1 upward through the support tube 7 and the connecting block 3, to prevent the circuit board body 1 from being deformed due to the pressure to the greatest extent.

[0062] Specifically, the reset component includes: the first slider 11 and the reset spring 13. The first slider 11 is slidably arranged on the reset base plate 4. An opening 12 for the first slider 11 to slide is formed on the reset base plate 4. One end of the reset spring 13 is fixedly installed in the opening 12, and the other end of the reset spring 13 is fixedly connected to the first slider 11.

[0063] By loading and unloading the connecting block 3, the reset rod 5, the connecting component and the reset base plate 4 are loaded and unloaded. When installing the circuit board body 1, it provides support, and after the installation is completed, it can be disassembled, greatly saving the installation space of the circuit board body 1.

[0064] Correspondingly, the preferred positioning component includes: a sliding base 15, a second slider 16, a pushing component, a driving component and a positioning component. The sliding base 15 is slidably arranged between the two connecting blocks 3. The second slider 16 is slidably arranged on the sliding base 15. A sliding groove 17 for the second slider 16 to slide is formed on the sliding base 15. The pushing component is arranged on the second slider 16. The driving component is arranged at one end of the pushing component. A set of positioning components are arranged on both sides of the driving component. Among them, the pushing component drives the driving component and the positioning component to slide on the sliding base 15, and the driving component drives the two sets of positioning components to clamp the bolt.

[0065] Specifically, the pushing component includes: a push rod 18, a housing 19 and a retaining ring 20. The push rod 18 is rotatably and slidably installed inside the support tube 7. The housing 19 is located on one side of the sliding base 15. The push rod 18 passes through the support tube 7, the second slider 16 and the housing 19 and extends into the interior of the housing 19. Four retaining rings 20 are fixedly installed on the push rod 18. The four retaining rings 20 are divided into two groups, which are respectively located on both sides of the second slider 16 and on both sides of the place where the housing 19 is penetrated by the push rod 18.

[0066] Among them, the driving component includes: a gear 21 and a toothed plate 22. One end of a push rod 18 passing through a housing 19 is fixedly installed with the gear 21. Two toothed plates 22 are slidably installed on the housing 19, and both of the two toothed plates 22 are in meshing engagement with the gear 21.

[0067] Specifically, each set of positioning components includes: a positioning arc plate 23 and a connecting bent rod 24. There are two positioning arc plates 23. The two positioning arc plates 23 are located on one side of the two toothed plates 22. The two positioning arc plates 23 are fixedly connected to the two toothed plates 22 respectively through two connecting bent rods 24. Among them, the push rod 18 drives the second slider 16 to move in the chute 17. When the second slider 16 slides to one end close to the support tube 7 in the chute 17, the two positioning arc plates 23 are aligned with the center points of the corresponding fastening holes 2. When the second slider 16 moves in the direction away from the support tube 7 and the second slider 16 slides to the other end of the chute 17, the positioning arc plate 23 will extend beyond the circuit board body 1, facilitating the alignment of the positioning arc plate 23 and the bolt.

[0068] The circuit board body 1 can be quickly installed on the bolt. By adjusting the two sets of positioning arc plates 23, the bolt can be quickly sleeved, thereby realizing the rapid positioning of the circuit board body 1. And after the circuit board body 1 is installed, the positioning arc plate 23 is adjusted again to make the positioning arc plate 23 away from the bolt, so as to realize the rapid disassembly of the sliding base 15 and the positioning arc plate 23.

[0069] In this embodiment, the anti-bending principle of the anti-bending PCB circuit board is as follows: Fix two connecting blocks 3 at the bottom of the circuit board body 1, then slide the sliding base 15 and the fixing plate 6 onto the connecting blocks 3 in sequence, so that the reset rod 5 and the reset base plate 4 move below the circuit board body 1. Then move the circuit board body 1 and the reset base plate 4 into the installation area, mostly between four bolts. Then push the push rod 18, and through the push rod 18, push the second slider 16, the housing 19, and the positioning arc plate 23 to move away from the circuit board body 1. Then rotate the push rod 18, and the push rod 18 drives the gear 21 to rotate, so that the two toothed plates 22 slide in the housing 19 in opposite directions, so that the four positioning arc plates 23 move away from each other. When the two groups of positioning arc plates 23 sleeve the two bolts, reverse the push rod 18, so that the four positioning arc plates 23 are driven by the toothed plates 22 to move closer to each other, that is, the four positioning arc plates 23 are in two groups, and the positioning arc plates 23 in each group move closer to and away from each other, so that the two groups of positioning arc plates 23 can clamp the bolts. Then push the circuit board body 1 to align the center points of the two groups of positioning arc plates 23 with the centers of the corresponding two fastening holes 2. Then fix the circuit board body 1 by screwing the nut onto the bolt. When the circuit board body 1 is subjected to a downward pressure, the support tube 7 and the sliding base 15 move downward. As the support tube 7, the sliding base 15, and the circuit board body 1 move downward, the reset rod 5 rotates on the first rotating base 9 and the second rotating base 10. At the same time, because the reset rod 5 is in an inclined state, when the circuit board body 1 is pushed downward or the middle position of the circuit board body 1 is bent downward, the reset rod 5 will push the first slider 11 to slide in the opening 12, and the downward pressure on the circuit board body 1 will be offset to the greatest extent by the reset spring 13. At the same time, when the circuit board body 1 is no longer subjected to a downward pressure, the reset spring 13 will drive the first slider 11 to reset, and at the same time, through the sliding of the first slider 11, the reset rod 5 will push the support tube 7 and the circuit board body 1 to reset. After the circuit board body 1 is installed, rotate the push rod 18 to drive the gear 21 to rotate by the push rod 18, so that the toothed plate 22 drives the positioning arc plate 23 to move away from the bolt, and then remove the connecting block 3 and pull out the connecting block 3 and the reset base plate 4.

[0070] It should be noted that when disassembling the reset base plate 4 and the sliding base 15, first pull out the pin 14, pull out the fixing plate 6 and the reset base plate 4, and finally, after pulling out the sliding base 15, remove the connecting block 3 from the circuit board body 1.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
