[0002] In the current use of power circuit boards, there are many problems that affect their service life. On the one hand, traditional circuit board installation methods mostly use screw fastening, soldering and other fixing methods. During installation, it is necessary to accurately position and tighten multiple screws, or fix them by soldering. The operation is cumbersome and time-consuming. Moreover, repeated disassembly and reassembly can easily damage the solder pads on the surface of the circuit board and strip the screw holes, affecting the normal use and service life of the circuit board.
[0003] The inventors believe that the following defects often exist: traditional installation methods often require complex positioning, a large number of fastening parts or special tools, the installation process is time-consuming and prone to errors, and if the installation is incorrect, it may lead to repeated disassembly, causing wear and tear on the circuit board body, reduced precision, and reduced reliability of the circuit board body; therefore, a long-life power circuit board is proposed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which often requires complex positioning, a large number of fastening parts or special tools, and the installation process is time-consuming and prone to errors. Therefore, a long-life power circuit board is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a long-life power circuit board, comprising a circuit board body, four heat dissipation fins mounted on the surface of the circuit board body, a mounting device provided on the lower surface of the circuit board body, the mounting device comprising a base plate, the base plate being slidably connected to the lower surface of the circuit board body, two fixing plates being fixedly connected to the upper surface of the base plate, a round rod being fixedly connected to one side of the fixing plate, a shaped frame being rotatably connected to one end of the round rod, a threaded rod being threaded into the shaped frame, and a fixing frame being rotatably connected to one end of the two threaded rods, the fixing frame being slidably connected to the circuit board body.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up the installation device, the circuit board body can be conveniently installed and disassembled, avoiding the traditional installation method that often requires complex positioning, a large number of fastening parts or special tools, and the installation process is time-consuming and prone to errors. If the installation is incorrect, it may lead to repeated disassembly, causing wear and tear on the circuit board body, reduced precision, and reduced reliability of the circuit board body, thus improving the practicality of the device.
[0007] Preferably, an absorbent pad is fixedly connected to one side of the irregularly shaped frame, and the size of the absorbent pad is adapted to the size of the irregularly shaped frame.
[0008] The aforementioned components achieve the following effect: they absorb the collision force between the irregular frame and the base plate, preventing damage to the irregular frame and shortening its service life if the worker rotates the irregular frame and then releases it after rotating it to a certain angle.
[0009] Preferably, a wedge is fixedly connected to one side of the fixing plate, and the surface of the wedge is slidably connected to the surface of the circuit board body.
[0010] The aforementioned components achieve the following effects: they calibrate the position of the circuit board body, reduce manual positioning deviations, ensure installation accuracy, and improve installation efficiency and the stability of the circuit board body after installation.
[0011] Preferably, an L-shaped plate is fixedly connected to the upper surface of the fixing plate, and the surface of the L-shaped plate is in contact with the irregular frame.
[0012] The effect achieved by the above-mentioned components is to limit the position of the irregular frame, so as to avoid the situation where the angle of the irregular frame needs to be constantly adjusted manually when the staff rotates the irregular frame, which would increase the workload of the staff when using the irregular frame.
[0013] Preferably, the surface of the circuit board body is provided with a cleaning device, which includes eight irregularly shaped compartments. The eight irregularly shaped compartments are all fixedly connected to the surface of the circuit board body. The eight irregularly shaped compartments are grouped in pairs. A push plate is slidably connected to the inner surface of each group of irregularly shaped compartments. A cleaning block is slidably inserted into the push plate. The surface of the cleaning block is slidably connected to the irregularly shaped compartment. A long rod is fixedly connected to the surface of the push plate. A single-hole plate is rotatably connected to the arc surface of the long rod. A bolt is threaded into the single-hole plate. The arc surface of the bolt is threadedly connected to the push plate.
[0014] The aforementioned components achieve the following effects: By setting up a cleaning device, the heat sink fins can be cleaned quickly, avoiding the need for staff to use a brush to clean the gaps between the heat sink fins bit by bit. Manual operation is prone to omissions and it is difficult to ensure that each heat sink fin is cleaned thoroughly, which affects the heat dissipation effect. Repeated brushing may also cause the brush to wear down, shed fibers, etc., contaminating the circuit board, or even damaging the heat sink fins due to improper operation, thus improving the reliability of the device.
[0015] Preferably, a spring is fixedly connected to the inner surface of the irregularly shaped compartment, and a square plate is fixedly connected to one end of the spring.
[0016] The effect achieved by the above components is to improve the stability of the push plate, avoid the push plate being affected by external forces, and prevent the push plate from sliding in the irregular chamber. The push plate drives the cleaning block to move, causing the cleaning block to stick to the heat sink fins to a certain extent, resulting in a decrease in the heat dissipation effect of the heat sink fins.
[0017] Preferably, a torsion spring is fitted onto the arc surface of the long rod, and the two ends of the torsion spring are fixedly connected to the long rod and the single-hole plate, respectively.
[0018] The aforementioned components achieve the following effect: they automatically open the single-hole plate while keeping it in the open state, facilitating further operations by the staff.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting up an installation device, the effect of convenient installation and disassembly of the circuit board body is achieved, avoiding the traditional installation method which often requires complex positioning, a large number of fastening parts or special tools, and the installation process is time-consuming and prone to errors.

[0021] 2. In this utility model, by setting up a cleaning device, the effect of quickly cleaning the heat dissipation fins is achieved. This avoids the need for workers to use a brush to clean the gaps between the heat dissipation fins bit by bit when cleaning the heat dissipation fins.

This improves the reliability of the device. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a long-life power circuit board, including a circuit board body 1, four heat dissipation fins 2 mounted on the surface of the circuit board body 1, and an installation device 3 provided on the lower surface of the circuit board body 1. By setting the installation device 3, the circuit board body 1 can be easily installed and disassembled, avoiding the need for complex positioning, a large number of fastening parts or special tools in traditional installation methods. The installation process is time-consuming and prone to errors. If the installation is incorrect, it may require repeated disassembly, causing wear and tear on the circuit board body 1, reducing its precision and reliability. This improves the practicality of the device. The surface of the circuit board body 1 is provided with a cleaning device 4, which achieves the effect of quickly cleaning the heat dissipation fins 2. This avoids the need for workers to use a brush to clean the gaps between the heat dissipation fins 2 bit by bit when cleaning the heat dissipation fins 2. Manual operation is prone to omissions and it is difficult to ensure that each heat dissipation fin 2 is cleaned properly, affecting the heat dissipation effect. Repeated brushing may also cause the brush to wear down, shed fibers, etc., contaminating the circuit board, or even damaging the heat dissipation fins 2 due to improper operation. This improves the reliability of the device.
[0029] The specific setup and function of the installation device 3 and the cleaning device 4 will be described in detail below.
[0030] Reference Figure 2As shown in this embodiment: the mounting device 3 includes a base plate 39, which is slidably connected to the lower surface of the circuit board body 1. Two fixing plates 31 are fixedly connected to the upper surface of the base plate 39. A round rod 32 is fixedly connected to one side of the fixing plate 31. A shaped frame 33 is rotatably connected to one end of the round rod 32. A threaded rod 34 is threaded into the shaped frame 33. A fixing frame 35 is rotatably connected to one end of the two threaded rods 34. The fixing frame 35 is slidably connected to the circuit board body 1. An absorbent pad 36 is fixedly connected to one side of the shaped frame 33. The size of the absorbent pad 36 is adapted to the size of the shaped frame 33. When the operator needs to disassemble the circuit board body 1, the operator first rotates the threaded rod 34 to drive the fixing frame 35 to rotate inside the shaped frame 33. The mechanism is operated until the arc surface of the fixing frame 35 separates from the circuit board body 1. At this time, the operator can rotate the irregular frame 33 at one end of the round rod 32. The irregular frame 33 drives the absorption pad 36 to move until the surface of the absorption pad 36 is in contact with the base plate 39. At this time, the collision force between the irregular frame 33 and the base plate 39 is absorbed, avoiding the situation where the operator releases the irregular frame 33 after rotating it at a certain angle, which may cause the irregular frame 33 to collide with the base plate 39, causing damage to the irregular frame 33 and shortening its service life. A wedge 37 is fixedly connected to one side of the fixing plate 31. The surface of the wedge 37 is slidably connected to the surface of the circuit board body 1. When installing the circuit board body 1, the worker first slides the circuit board body 1 on the surface of the base plate 39 until it is in contact with the surface of the inclined block 37. The worker can then continue to slide the circuit board body 1 on the surface of the inclined block 37 until its position is calibrated. After the circuit board body 1 has moved to a certain position, the worker can rotate the threaded rod 34 within the irregular frame 33. The threaded rod 34 moves the fixing frame 35 until it is inserted into the circuit board body 1. This achieves the effect of calibrating the position of the circuit board body 1, reducing manual positioning errors, ensuring installation accuracy, and improving installation efficiency and circuit board performance. To ensure the stability of the main body 1 after installation, an L-shaped plate 38 is fixedly connected to the upper surface of the fixing plate 31. The surface of the L-shaped plate 38 is in contact with the irregular frame 33. When the operator needs to install the circuit board main body 1, the operator can first move the circuit board main body 1 to a suitable position, and then rotate the irregular frame 33 at one end of the round rod 32 until the surface of the irregular frame 33 is in contact with the L-shaped plate 38. At this time, the operator can rotate the threaded rod 34 inside the irregular frame 33. This achieves the effect of limiting the position of the irregular frame 33, avoiding the situation where the operator needs to constantly adjust the angle of the irregular frame 33 when rotating it, which would increase the workload of the operator when using the irregular frame 33.
[0031] Reference Figure 3 , Figure 4 and Figure 5 As shown, specifically, the cleaning device 4 includes eight irregularly shaped compartments 41, each fixedly connected to the surface of the circuit board body 1. The eight compartments 41 are grouped in pairs. A push plate 42 is slidably connected to the inner surface of each group of compartments 41. A cleaning block 43 is slidably inserted into the push plate 42, and the surface of the cleaning block 43 is slidably connected to the irregularly shaped compartment 41. A long rod 46 is fixedly connected to the surface of the push plate 42. A single-hole plate 47 is rotatably connected to the arc surface of the long rod 46. A bolt 48 is threaded into the single-hole plate 47, and the arc surface of the bolt 48 is rotatably connected to... The push plate 42 is threadedly connected, and a spring 45 is fixedly connected to the inner surface of the irregularly shaped chamber 41. A square plate 44 is fixedly connected to one end of the spring 45. When the worker finishes using the cleaning block 43, the worker pushes the square plate 44 to slide inside the irregularly shaped chamber 41. At this time, the spring 45 is compressed until the square plate 44 no longer affects the movement of the push plate 42. Then the worker pushes the square plate 44 until it is in contact with the surface of the push plate 42. At this time, the worker releases the square plate 44, and the rebound force of the spring 45 drives the square plate 44 to move within the irregularly shaped chamber. The square plate 44 slides within the 41, causing the push plate 42 to move. The push plate 42 then moves the cleaning block 43 until the cleaning block 43 is completely separated from the surface of the heat sink 2. This improves the stability of the push plate 42 and prevents it from being affected by external forces, which could cause the push plate 42 to slide within the irregularly shaped compartment 41. The push plate 42 then moves the cleaning block 43, causing it to adhere to the heat sink 2 to some extent, resulting in a decrease in the heat dissipation effect of the heat sink 2. The arc surface of the long rod 46 is fitted with a torsion plate. Spring 49 and torsion spring 49 are fixedly connected at both ends to long rod 46 and single-hole plate 47, respectively. When the staff needs to disassemble cleaning block 43 for cleaning, the staff first rotates bolt 48 inside push plate 42 until the arc surface of bolt 48 separates from push plate 42. At this time, the torque of torsion spring 49 drives single-hole plate 47 to move until single-hole plate 47 no longer affects the movement of cleaning block 43. At this time, the effect of automatically opening single-hole plate 47 is achieved, and single-hole plate 47 is kept in the open state to facilitate further operation by the staff.
[0032] Working principle: When the operator needs to disassemble the circuit board body 1, firstly, the operator rotates the threaded rod 34 to drive the fixing bracket 35 to rotate within the irregular frame 33 until the arc surface of the fixing bracket 35 separates from the circuit board body 1. At this time, the operator can rotate the irregular frame 33 at one end of the round rod 32, causing the irregular frame 33 to move the absorbent pad 36 until the surface of the absorbent pad 36 is in contact with the base plate 39. When the operator needs to install the circuit board body 1, firstly, the operator pushes the circuit board body 1 to slide on the surface of the base plate 39 until the circuit board body 1 is in contact with the surface of the inclined block 37. At this time, the operator can continue to push the circuit board body 1, and the circuit board body 1 slides on the surface of the inclined block 37 until the circuit board body 1 is in contact with the surface of the inclined block 37. After the position of the circuit board body 1 is calibrated, the operator rotates the irregular frame 33 at one end of the round rod 32 until the surface of the irregular frame 33 is in contact with the L-shaped plate 38. Then, the operator can rotate the threaded rod 34 inside the irregular frame 33. The threaded rod 34 drives the fixing frame 35 to move until the fixing frame 35 is inserted into the circuit board body 1. This achieves the effect of convenient installation and disassembly of the circuit board body 1. Traditional installation methods often require complex positioning, a large number of fastening parts or special tools, which can lead to a time-consuming and error-prone installation process. If the installation is incorrect, it may require repeated disassembly, causing wear and tear on the circuit board body 1, a decrease in precision, and a reduction in the reliability of the circuit board body 1. This improves the practicality of the device.
[0033] When the worker finishes using the cleaning block 43, the worker pushes the square plate 44 to slide within the irregularly shaped compartment 41. At this time, the spring 45 is compressed until the square plate 44 no longer affects the movement of the push plate 42. Then, the worker pushes the square plate 44 until it is in contact with the surface of the push plate 42. At this point, the worker releases the square plate 44, and the rebound force of the spring 45 causes the square plate 44 to slide within the irregularly shaped compartment 41. The square plate 44 drives the push plate 42 to move, and the push plate 42 drives the cleaning block 43 to move until the cleaning block 43 is completely separated from the surface of the heat sink fin 2. When the worker needs to disassemble the cleaning block 43 for cleaning, the worker first rotates the bolt 48. The device rotates within the push plate 42 until the arc surface of the bolt 48 separates from the push plate 42. At this point, the torque of the torsion spring 49 drives the single-hole plate 47 to move until the single-hole plate 47 no longer affects the movement of the cleaning block 43. This achieves the effect of quickly cleaning the heat sink fins 2, avoiding the need for staff to use a brush to clean the gaps between the heat sink fins 2 bit by bit when cleaning the heat sink fins 2. Manual operation is prone to omissions and it is difficult to ensure that each heat sink fin 2 is cleaned properly, which affects the heat dissipation effect. Repeated brush operation may also cause the brush to wear down, lose fibers, etc., contaminate the circuit board, or even damage the heat sink fins 2 due to improper operation, thus improving the reliability of the device.
