Description

Technical Field

[0001] This utility model relates to the field of control circuit board technology, and in particular to a high-strength control circuit board. Background Technology

[0002] With the rapid development of electronic technology, control circuit boards are increasingly widely used in various electronic devices, and their performance directly affects the overall operational stability of the equipment. In actual production and use, in order to meet functional requirements, electronic components of various sizes and shapes are often densely arranged on the surface of the circuit board.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: when the circuit board needs to be placed on the mounting base for operation, due to the different sizes of the components on the circuit board, it cannot fit the upper surface of the mounting base during the placement process, resulting in a certain horizontal tilt after placement. The tilted circuit board makes it difficult for the operator to accurately control the angle and position of operation, greatly increasing the difficulty of operation and reducing assembly efficiency and quality; therefore, a high-strength control circuit board is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, when a circuit board needs to be placed on a mounting base for operation, the different sizes of the components on the circuit board make it impossible to fit the upper surface of the mounting base during placement, resulting in a certain horizontal tilt after placement. The tilted circuit board makes it difficult for the operator to accurately control the angle and position of operation, greatly increasing the difficulty of operation and reducing assembly efficiency and quality. Therefore, a high-strength control circuit board is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength control circuit board, including a mounting base, a first positioning frame fixedly connected to the upper surface of the mounting base, two sliding grooves formed on the upper surface of the mounting base, a sliding rod fixedly connected to the inner wall of each of the two sliding grooves, a slider slidably connected to the arc surface of the sliding rod, a spring sleeved on the arc surface of the sliding rod, the two ends of the spring being fixedly connected to the slider and the sliding groove respectively, a second positioning frame fixedly connected to the upper surface of the two sliders, the second positioning frame being slidably connected to the upper surface of the mounting base, and a circuit board body slidably connected to the inner wall of the first positioning frame and the second positioning frame.

[0006] The effect achieved by the above components is as follows: the circuit board body is initially positioned by the first positioning frame, and then, with the synergistic action of the second positioning frame, slider and spring, it can be flexibly adjusted according to the specific size of the circuit board body, so that the circuit board is suspended above the mounting base surface for positioning. This effectively avoids the gaps that may occur when the circuit board is placed on the mounting base surface due to the large number of components on the circuit board surface, which may lead to tilting. This significantly enhances the stability and reliability of the circuit board body after placement, and facilitates the operation of subsequent operators.

[0007] Preferably, an L-shaped block is fixedly connected to one side of the second positioning frame. The L-shaped block fixedly connected to one side of the second positioning frame provides a convenient point of leverage for the operator.

[0008] The effect achieved by the above components is that the operator can easily pull the second positioning frame backward by holding the L-shaped block, which makes it easy to flexibly adjust its position according to the size of the circuit board, thus improving the convenience and efficiency of operation.

[0009] Preferably, a first square groove is provided on one side of the mounting base, a threaded rod is rotatably connected inside the mounting base, the threaded rod passes through the first square groove, a round shaft is fixedly connected to one end of the threaded rod, a push bracket is threadedly connected to the arc surface of the threaded rod, a second square groove is provided on the side of the mounting base away from the threaded rod, a long rod is fixedly connected to the inner wall of the second square groove, the push bracket is slidably connected to the arc surface of the long rod, a clamping plate is fixedly connected to the surface of the push bracket, and the clamping plate abuts against the surface of the circuit board body.

[0010] The effect achieved by the above components is as follows: by opening a first square groove and setting a threaded rod on one side of the mounting base, the pusher can be driven to slide along the long rod in conjunction with the rotation of the round shaft. The guiding effect of the long rod ensures the stability of the pusher's movement trajectory and avoids deviation or shaking. Subsequently, the pusher can drive the clamping plate to make tight contact with the surface of the circuit board body, which can effectively suppress the problem of vibration and displacement of the circuit board body during operation and improve the stability of the circuit board body during operations such as soldering.

[0011] Preferably, the circular arc surface of the circular shaft is provided with a plurality of strip grooves, and the plurality of strip grooves are arranged in a circumferential array.

[0012] The effect achieved by the above-mentioned components is that the groove increases the friction between the operator's fingers and the round shaft, making it more effortless and convenient to use the round shaft.

[0013] Preferably, a clamping pad is fixedly connected to the inner wall of the clamping plate, and the clamping pad is made of silicone rubber.

[0014] The aforementioned components achieve the following effects: the silicone rubber pads, with their excellent elasticity and flexibility, can tightly adhere to the surface of the circuit board, filling the tiny gaps between the clamps and the circuit board, thus enhancing clamping stability. Simultaneously, the soft texture of silicone rubber prevents direct contact between the clamps and the circuit board, avoiding surface scratches and component damage, thus providing cushioning and protection.

[0015] Preferably, the lower surface of the pusher is fixedly connected to two ball bearings, which are slidably connected to the bottom surfaces of the inner walls of the first and second square grooves, respectively.

[0016] The effect achieved by the above components is that the ball bearings convert the sliding friction between the pusher and the bottom surface of the square groove of the mounting base into rolling friction, which greatly reduces the resistance of the pusher during movement, making it easier and smoother for the operator to rotate the round shaft to adjust the position of the clamp.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, the circuit board body is initially positioned by the first positioning frame, and then, with the synergistic action of the second positioning frame, slider and spring, it can be flexibly adjusted according to the specific size of the circuit board body, so that the circuit board is suspended above the mounting base surface for positioning. This effectively avoids the situation where gaps may occur when the circuit board is placed on the mounting base surface due to the large number of components on the circuit board surface, which may lead to tilting. This significantly enhances the stability and reliability of the circuit board body after placement, and facilitates the operation of subsequent operators. Attached Figure Description

Detailed Implementation

[0025] Reference Figures 1-5As shown, this utility model provides a technical solution: a high-strength control circuit board, including a mounting base 1. A first positioning frame 3 is fixedly connected to the upper surface of the mounting base 1. Two sliding grooves 4 are formed on the upper surface of the mounting base 1. Sliding rods 5 are fixedly connected to the inner walls of the two sliding grooves 4. Sliding blocks 6 are slidably connected to the arc surface of the sliding rods 5. Springs 7 are sleeved on the arc surface of the sliding rods 5. The two ends of the springs 7 are fixedly connected to the sliding blocks 6 and the sliding grooves 4, respectively. A second positioning frame 8 is fixedly connected to the upper surface of the two sliding blocks 6. The second positioning frame 8 is slidably connected to the upper surface of the mounting base 1. The circuit board body 2 is slidably connected to the inner wall of the second positioning frame 8. The circuit board body 2 is initially positioned by the first positioning frame 3. Then, with the synergistic action of the second positioning frame 8, the slider 6 and the spring 7, it can be flexibly adjusted according to the specific size of the circuit board body 2, so that the circuit board is suspended above the surface of the mounting base 1 for positioning. This effectively avoids the gap that may occur when the circuit board is placed on the surface of the mounting base 1 due to the large number of components on the surface of the circuit board, which may lead to tilting. This significantly enhances the stability and reliability of the circuit board body 2 after placement, and facilitates the operation of subsequent operators. An L-shaped block 9 is fixedly connected to one side of the second positioning frame 8.The L-shaped block 9 fixedly connected to one side of the second positioning frame 8 provides a convenient point of leverage for the operator. The operator can easily pull the second positioning frame 8 backward by holding the L-shaped block 9, which facilitates flexible adjustment of its position according to the size of the circuit board, improving the convenience and efficiency of operation. A first square groove 10 is opened on one side of the mounting base 1. A threaded rod 11 is rotatably connected inside the mounting base 1. The threaded rod 11 passes through the first square groove 10. A round shaft 12 is fixedly connected to one end of the threaded rod 11. A pusher 15 is threadedly connected to the arc surface of the threaded rod 11. A second square groove 13 is opened on the side of the mounting base 1 away from the threaded rod 11. A long rod 14 is fixedly connected to the inner wall of the second square groove 13. The pusher 15 is slidably connected to the arc surface of the long rod 14. A clamping plate 18 is fixedly connected to the surface of the pusher 15. The clamping plate 18 abuts against the surface of the circuit board body 2. By opening a first square groove 10 on one side of the mounting base 1, the operation is more convenient and efficient. A threaded rod 11 is provided, which, in conjunction with the rotation of the round shaft 12, drives the pusher 15 to slide along the long rod 14. The guiding effect of the long rod 14 ensures the stability of the movement trajectory of the pusher 15, avoiding deviation or shaking. Subsequently, the pusher 15 can drive the clamping plate 18 to make tight contact with the surface of the circuit board body 2, which can effectively suppress the problem of vibration and displacement of the circuit board body 2 during operation, and improve the stability of the circuit board body 2 during operations such as soldering. The round shaft 12 has several strip grooves 16 on its arc surface, which are arranged in a circumferential array. The strip grooves 16 increase the friction between the operator's fingers and the round shaft 12, making it more labor-saving and convenient to use the round shaft 12. A clamping pad 19 is fixedly connected to the inner wall of the clamping plate 18. The clamping pad 19 is made of silicone rubber. With its good elasticity and flexibility, the silicone rubber clamping pad 19 can fit tightly against the surface of the circuit board body 2, fill the tiny gaps between the clamping plate 18 and the circuit board, and enhance the clamping stability. Meanwhile, the soft texture of silicone rubber can prevent the clamping plate 18 from directly contacting the circuit board, which could cause surface scratches or component damage, thus providing a buffering and protective function. Two balls 17 are fixedly connected to the lower surface of the pusher 15. The two balls 17 are slidably connected to the bottom surface of the inner wall of the first square groove 10 and the second square groove 13, respectively. The balls 17 convert the sliding friction between the pusher 15 and the bottom surface of the inner wall of the square groove of the mounting base 1 into rolling friction, which greatly reduces the resistance of the pusher 15 during movement, making it easier and smoother for the operator to rotate the round shaft 12 to adjust the position of the clamping plate 18.

[0026] The working principle is as follows: In the initial positioning stage, the first positioning frame 3 serves as the starting support point for the installation of the circuit board body 2, providing preliminary positioning for one side of the circuit board body 2 and determining the basic installation position of the circuit board body 2. When placing the circuit board body 2, according to its specific dimensions, the L-shaped block on one side of the second positioning frame 8 can be pulled by external force to make the second positioning frame 8 slide on the upper surface of the mounting base 1. During this process, the slider 6 slides along the slide bar 5 in the slide groove 4, while compressing or stretching the spring 7. The elastic force generated by the spring 7 makes the second positioning frame 8 fit tightly against the circuit board body 2, allowing the circuit board body 2 to suspend above the surface of the mounting base 1. This positioning method effectively avoids the problem of gaps between the components and the mounting base 1 when the circuit board body 2 is placed on the surface of the mounting base 1 due to the large number of components on its surface, which could cause the circuit board body 2 to tilt, thus significantly improving the stability of the circuit board body 2 after installation. During the fixing phase, rotating the circular shaft 12 causes the threaded rod 11 to rotate accordingly. The circular grooves 16 arranged in a circumferential array on the arc surface of the circular shaft 12 increase the friction between the operator's fingers and the circular shaft 12, making it easier and less strenuous to rotate. The rotational motion of the threaded rod 11 is converted into the linear motion of the pusher 15 along the long rod 14. The long rod 14 is fixed to the inner wall of the second square groove 13, providing guidance for the movement of the pusher 15 and ensuring the stability of the pusher 15's movement trajectory. As the pusher 15 slides, the clamping plate 18 fixed on its surface gradually approaches the circuit board body 2 until it comes into close contact with the surface of the circuit board body 2, thereby achieving a stable clamping of the circuit board body 2. In addition, the silicone rubber pad 19 fixed to the inner wall of the clamping plate 18 further enhances the fixing effect and protective performance. The silicone rubber clamping pad 19, with its excellent elasticity and flexibility, can closely adhere to the surface of the circuit board body 2, filling the tiny gaps between the clamping plate 18 and the circuit board body 2. This enhances clamping stability while preventing direct contact between the clamping plate 18 and the circuit board body 2, thus avoiding surface scratches and component damage, and providing cushioning and protection. Meanwhile, the ball bearings 17 fixedly connected to the lower surface of the pusher 15 convert the sliding friction between the pusher 15 and the bottom surface of the square groove in the mounting base 1 into rolling friction, significantly reducing the resistance of the pusher 15 during movement. This makes it easier and smoother for the operator to adjust the position of the clamping plate 18 by rotating the round shaft 12, effectively improving the convenience and efficiency of the entire installation process.
