Description

Technical Field

[0001] This utility model relates to the field of PC board production and processing technology, specifically to a lightweight PC board with honeycomb reinforcing ribs. Background Technology

[0002] PC (polycarbonate) boards are high-performance engineering plastic sheets with excellent insulation properties, as well as a certain degree of strength and hardness. They can withstand the weight of electronic components and various external forces during assembly and use, such as insertion and extraction forces and vibrations, without easily deforming or being damaged. This provides stable support for electronic components. Therefore, PC boards are commonly used as printed circuit boards in the production process. Furthermore, to enhance the strength of the circuit board itself, honeycomb-shaped reinforcing ribs are often incorporated to reduce the possibility of damage from external forces. Currently, in the production and processing of printed circuit boards, they are typically fixed to mounting bases with screws. This requires workers to perform tedious operations such as alignment and screw tightening. If the screws are not tightened properly, the circuit board may become loose or shift during use, leading to instability in electronic equipment and affecting production efficiency. Therefore, we propose a lightweight PC board with honeycomb-shaped reinforcing ribs. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight PC board with honeycomb reinforcing ribs to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a lightweight PC board with honeycomb-shaped reinforcing ribs, including a reinforced circuit board. A mounting base is provided on the lower side of the reinforced circuit board, and a fixing device is provided inside the mounting base. The fixing device is used to fix the reinforced circuit board to the mounting base. The fixing device includes a sliding plate, a locking block is fixedly connected to one side of the sliding plate, slots are formed on both sides of the fixing device, and a sliding groove is formed on one side of the slot. The sliding plate is slidably disposed inside the sliding groove. A spring located inside the sliding groove is fixedly connected to the side of the sliding plate away from the locking block. An L-shaped connecting rod is fixedly connected to the lower side of the reinforced circuit board. The crossbar of the L-shaped connecting rod is movably inserted into the slot. A locking groove is formed on the side of the crossbar near its end, and the locking block is movably engaged inside the locking groove.

[0005] As a further improvement to this technical solution, limit grooves are provided on the upper and lower sides of the sliding groove, and limit blocks are slidably arranged inside the limit grooves, with the limit blocks fixedly installed on the sliding plate.

[0006] As a further improvement to this technical solution, a telescopic rod is fixedly installed inside the sliding groove, the piston rod end of the telescopic rod is fixedly connected to the side of the sliding plate away from the locking block, and the spring is sleeved on the outside of the telescopic rod.

[0007] As a further improvement to this technical solution, a connecting block is fixedly mounted on the sliding plate between the two springs. One end of the connecting block passes through the mounting base and extends outward. A slider is provided inside the mounting base, and a hinge rod is hinged between the connecting block and the slider.

[0008] As a further improvement to this technical solution, a fixing block is fixedly installed on the inner side of the mounting base near the center. A guide groove is provided on the side of the fixing block near the slider. A guide block is slidably arranged inside the guide groove. The guide block is fixedly installed on the slider.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this lightweight PC board with honeycomb reinforcing ribs, an L-shaped connecting rod fixed to the reinforced circuit board is inserted into the bottom of the slot, and the sliding plate is pushed out by the elastic thrust of the spring. The card block fixed on the sliding plate is then locked inside the slot, thereby fixing the reinforced circuit board on the mounting base. This not only reduces the operation process for workers and improves work efficiency, but also avoids the situation where the circuit board is loose or shifted due to the screws not being tightened, which could lead to instability of electronic equipment.

[0019] Example 1

[0020] Please see Figures 1-4 As shown, this embodiment provides a lightweight PC board with honeycomb-shaped reinforcing ribs, including a reinforced circuit board 1. The lower surface of the reinforced circuit board 1 is provided with honeycomb-shaped reinforcing ribs. A mounting base 10 is provided on the lower side of the reinforced circuit board 1. A fixing device 2 is provided inside the mounting base 10 to fix the reinforced circuit board 1 onto the mounting base 10. The fixing device 2 includes a sliding plate 21. A locking block 22 is fixedly connected to one side of the sliding plate 21. Slots 3 are formed on both sides of the fixing device 2. A sliding groove 6 is formed on one side of the slots 3. The sliding plate 21 is slidably disposed inside the sliding groove 6. The side of the sliding plate 21 away from the locking block 22... A spring 23 is fixedly connected inside the sliding groove 6. An L-shaped connecting rod 4 is fixedly connected to the lower side of the reinforced circuit board 1. The crossbar of the L-shaped connecting rod 4 is movably inserted into the slot 3. A slot 5 is opened on the side of the crossbar of the L-shaped connecting rod 4 near the end. The locking block 22 is movably locked inside the slot 5. When the L-shaped connecting rod 4 fixed to the lower side of the reinforced circuit board 1 is inserted into the bottom of the slot 3, the elastic pushing force applied to the sliding plate 21 by the spring 23 pushes the sliding plate 21 out, so that the locking block 22 fixed on the sliding plate 21 is locked inside the slot 5, thereby fixing the reinforced circuit board 1 on the mounting base 10. The operation is convenient.

[0021] Please see Figure 3 and Figure 4As shown, a telescopic rod 25 is fixedly installed inside the sliding groove 6. The piston rod end of the telescopic rod 25 is fixedly connected to the side of the sliding plate 21 away from the locking block 22. A spring 23 is sleeved on the outside of the telescopic rod 25. The telescopic rod 25 supports the spring 23, preventing the spring 23 from deforming due to uneven force during repeated deformation, which would affect the movement of the sliding plate 21 and thus affect the use of the device. This protects the device and extends its service life. At the same time, limit grooves 7 are opened on the upper and lower sides of the sliding groove 6. Limit blocks 24 are slidably installed inside the limit grooves 7. The limit blocks 24 are fixedly installed on the sliding plate 21. When the sliding plate 21 slides inside the sliding groove 6, the sliding of the limit blocks 24 inside the limit grooves 7 limits the position of the sliding plate 21, preventing the sliding plate 21 from slipping out of the sliding groove 6 and causing device failure, thus making the device more stable.

[0022] Please see Figure 3 and Figure 4 As shown, a connecting block 26 is fixedly mounted on the sliding plate 21 between the two springs 23. One end of the connecting block 26 passes through the mounting base 10 and extends outward. A slider 27 is provided inside the mounting base 10. A hinge rod 28 is hinged between the connecting block 26 and the slider 27. When the slider 27 is pressed down, the two connecting blocks 26 are pulled towards each other through the hinge rod 28 and the hinge between the connecting block 26 and the slider 27. This causes the sliding plate 21 to slide away from the L-shaped connecting rod 4, causing the locking block 22 to disengage from the slot 5, thus allowing the reinforced circuit board 1 to be removed from the mounting base 10. The device is easy to disassemble and operate. A fixing block 8 is fixedly installed on the inner side of the mounting base 10 near the middle. A guide groove 9 is opened on the side of the fixing block 8 near the slider 27. A guide block 29 is slidably arranged inside the guide groove 9. The guide block 29 is fixedly installed on the slider 27. When the slider 27 is pushed to move downward, the slider 27 is guided by the sliding of the guide block 29 inside the guide groove 9. This prevents the slider 27 from tilting due to uneven force during the sliding process, which would cause only one side of the connecting block 26 to slide. This makes the device more stable when disassembling the reinforced circuit board 1.

[0023] In this embodiment, a lightweight PC board with honeycomb reinforcing ribs is used in the following way: the user inserts the L-shaped connecting rod 4, which is fixed on the reinforcing circuit board 1, into the bottom of the slot 3. The spring 23 applies an elastic pushing force to the sliding plate 21, pushing the sliding plate 21 out. This causes the locking block 22, which is fixed on the sliding plate 21, to be locked inside the slot 5, thereby fixing the reinforcing circuit board 1 on the mounting base 10. When it is necessary to remove the reinforcing circuit board 1 fixed on the mounting base 10, the user pushes the slider 27 downward to slide. The hinge rod 28 and the connecting block 26 and the slider 27 are hinged to make the two connecting blocks 26 slide towards each other, thereby pulling the two sliding plates 21 to slide, causing the locking block 22 to disengage from the slot 5, and then the reinforcing circuit board 1 can be pushed out.
