[0002] Circuit boards are an indispensable basic component in electronic devices, used to connect electronic components and realize the function of circuits. Circuit boards are usually composed of three parts: substrate, copper foil and solder mask. Circuit boards are tools used to install corresponding electronic devices and linearly conduct between multiple electronic devices. Flexural strength is a parameter that describes the material's ability to withstand complex stress.

[0003] Currently, circuit boards do not have high flexural strength and are prone to deformation or damage under pressure, affecting their normal use and causing inconvenience to users. Therefore, there is a need for a convenient circuit board with high flexural strength to solve the problem of circuit boards being easily damaged due to their low flexural strength in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a convenient high flexural strength circuit board, which solves the problem that existing circuit boards are prone to damage due to their low flexural strength during use.

[0005] To achieve the above objectives, a convenient high flexural strength circuit board is provided, including a flexural frame, an installation groove inside the flexural frame, a circuit board body correspondingly installed inside the installation groove, limit blocks fixedly connected to both sides of the lower end of the circuit board body, and limit slots extending through both ends of the bottom of the installation groove, with the limit blocks corresponding to the limit slots.

[0006] A slot is formed through the middle of the bottom side of the mounting groove. A bidirectional screw is rotatably connected to the middle of the slot. A handle is fixedly connected to the outer end of the bidirectional screw. Two connecting brackets are threaded onto the bidirectional screw.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a convenient high flexural strength circuit board, including a flexural frame 1, an installation groove 10 is provided inside the flexural frame 1, a circuit board body 6 is installed inside the installation groove 10, and limit blocks 19 are fixedly connected to both sides of the lower end of the circuit board body 6. Limit grooves 11 are provided through the bottom ends of the installation groove 10, and the limit blocks 19 correspond to the limit grooves 11. The quick correspondence between the limit blocks 19 and the limit grooves 11 can ensure that the staff can quickly install the circuit board body 6 inside the flexural frame 1.

[0024] A slot 9 is formed through the center of the bottom side of the mounting groove 10. A bidirectional screw 14 is rotatably connected to the center of the slot 9. A handle 13 is fixedly connected to the outer end of the bidirectional screw 14. Two connecting brackets 17 are threaded onto the bidirectional screw 14. A connecting rod 12 is rotatably connected to both ends of the connecting bracket 17. A rotating component 15 is rotatably connected to the other end of the connecting rod 12. A positioning block 16 is fixedly connected to the other end of the rotating component 15. The positioning block 16 is movably connected inside the limiting groove 11. A positioning groove 20 is formed through the inside of the limiting block 11. The positioning block 16 corresponds to the positioning groove 20. The slot 9 is close to the rotating component 11. The two ends of the moving part 15 are fixedly connected to the limiting frame 18. Rotating the outer handle 13 drives the bidirectional screw 14 to rotate. Under the action of the threaded connection, the two connecting frames 17 can be brought closer to each other. At this time, through the transmission between the connecting rods 12, the rotating plate 16 and the positioning block 16 can be driven to move gradually into the interior of the limiting groove 11, ensuring that the positioning block 16 can enter the interior of the positioning groove 20 to fix the circuit board body 6. The limiting frame 18 can limit the movement stroke of the rotating part 15 to prevent the rotating part 15 from leaving the interior of the groove, so as to ensure the smooth operation of the entire positioning assembly.

[0025] The outer four ends of the anti-flexure frame 1 are fixedly connected to the fixing blocks 4. The inside of the fixing blocks 4 is slidably connected to the slide rod 7. The lower end of the slide rod 7 is fixedly connected to the base plate 3. The upper end of the slide rod 7 is fixedly connected to the limit plate 5. A spring 8 is sleeved on the slide rod 7. The upper end of the spring 8 is fixedly connected to the fixing blocks 4, and the lower end is fixedly connected to the base plate 3. When longitudinal pressure appears on the top of the circuit board body 6, the circuit board body can move down along the slide rod 7 with the fixing blocks 4 to squeeze the spring 8, providing a certain buffer space for the circuit board body 6. After the pressure disappears, the spring 8 can help the circuit board body 6 to reset, improving the flexural strength of the entire circuit board body 6.

[0026] Two sets of positioning parts 2 are fixedly connected to one end of the base plate 3 near the slide bar 7. The positioning parts 2 can fix the entire anti-flexure frame 1.

[0027] Working principle: In use, the limiting blocks 19 at both ends of the circuit board body 6 are aligned with the limiting grooves 11 inside the mounting groove 10, thereby quickly installing the circuit board body 6 inside the anti-flex frame 1. Then, the outer handle 13 is rotated to drive the bidirectional screw 14 to rotate. Under the action of the threaded connection, the two connecting frames 17 can be brought closer to each other. At this time, through the transmission between the connecting rods 12, the rotating plate 16 and the positioning block 16 can be driven to move gradually into the limiting groove 11, ensuring that the positioning block 16 can enter the positioning groove 20 to fix the circuit board body 6. The anti-flex frame 1 can effectively improve the flexural strength of the circuit board body 6. At the same time, when longitudinal pressure appears on the top of the circuit board body 6, the circuit board body can move down along the slide rod 7 with the fixing block 4 to squeeze the spring 8, providing a certain buffer space for the circuit board body 6. After the pressure is removed, the spring 8 can help the circuit board body 6 to reset.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
