[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 As shown, a corrosion-resistant circuit board includes a circuit board body 1. The circuit board body 1 is provided with a mounting structure 2. The mounting structure 2 includes a mounting post 201 mounted on the circuit board body 1. A rubber pad 202 is slidably connected to the mounting post 201. A slider 203 is fixedly connected to the rubber pad 202. A drive plate 208 is slidably connected inside the mounting post 201. The drive plate 208 and the slider 203 are slidably engaged. A sliding plate 204 is slidably connected inside the mounting post 201. A lead screw 205 is rotatably connected inside the mounting post 201. The sliding plate 204 and the lead screw 205 are threadedly connected.

[0022] As a technical optimization of this utility model, a guide rod 207 is fixedly connected inside the mounting post 201, the slide plate 204 is slidably connected to the guide rod 207, a guide plate 206 is fixedly connected to the slider 203, and a drive plate 208 is slidably connected to the guide plate 206. When the circuit board body 1 needs to be installed on the device, the mounting post 201 is inserted into the mounting hole of the device, and then the lead screw 205 is inserted through the hexagonal sleeve. Rotating the lead screw 205 will cause the slide plate 204 to slide towards the slider 203. When the slide plate 204 slides, it drives the drive plate 208 to slide and will interact with the guide rod 207. The sliding engagement of the guide rod 207 makes the sliding plate 204 slide more smoothly. At the same time, the drive plate 208 drives the two sliders 203 to slide in opposite directions. The drive plate 208 will slide in engagement with the guide plate 206. The guide plate 206 makes the sliding plate 208 slide more smoothly. The sliders 203 drive the rubber pad 202 to slide, so that the rubber pad 202 is pressed against the inner wall of the equipment mounting hole, thus completing the fixation. By driving the rubber pad 202 to press against the inner wall of the mounting hole through the sliding plate 204, the problem of stripping of threads, which is common in traditional bolt installation, is avoided. This improves the installation stability of the circuit board body 1 and ensures the normal use of the equipment.

[0023] As a technical optimization of this utility model, a replacement structure 3 is provided between the circuit board body 1 and the mounting post 201. The replacement structure 3 includes four mounting rings 301 fixedly connected to the circuit board body 1. The mounting post 201 is slidably connected to the mounting rings 301. A connecting block 302 is fixedly connected to the mounting post 201, and the connecting block 302 is slidably connected to the mounting ring 301. A threaded ring 304 is threadedly connected to the mounting ring 301. A ball bearing 303 is rollingly connected to the connecting block 302, and the threaded ring 304 and the ball bearing 303 are in rolling engagement. When it is necessary to replace the mounting post 201 of different lengths, rotate the threaded ring 304 so that it is no longer threadedly connected to the mounting ring 301. Slide the mounting post 201 and the connecting block 302 along the mounting ring 301 to install the mounting post 201 of different lengths onto the mounting ring 301. After installation, thread the threaded ring 304 into the mounting ring 301 to complete the installation. The ball bearing 303 reduces the friction between it and the threaded ring 304. Replacing the mounting post 201 of different lengths can adapt to installation requirements when a specific distance from the equipment is required, thus improving the versatility of the circuit board body 1.

[0024] As a technical optimization of this utility model, the circuit board body 1 is provided with a heat dissipation structure 4. The heat dissipation structure 4 includes a guide rail 401 fixedly connected to the circuit board body 1, two mounting blocks 402 slidably connected to the guide rail 401, two vertical rods 403 fixedly connected to the mounting blocks 402, a fan 404 installed between the two vertical rods 403, a heat sink 405 fixedly connected to the circuit board body 1, a limit rod 406 slidably connected to the mounting blocks 402, multiple limit holes 407 provided on the guide rail 401, the limit rod 406 engaging with one of the limit holes 407, a guide block 408 fixedly connected to the limit rod 406, the guide block 408 slidably connected to the mounting block 402, the cross-section of the limit rod 406 is L-shaped, and a spring 408 is fixedly connected between the guide block 408 and the mounting block 402. 9. When heat dissipation is required for the circuit board body 1, the heat of the circuit board body 1 is conducted to the heat sink 405, and the fan 404 is activated. The fan 404 removes the heat from the heat sink 405 and the circuit board body 1, thus achieving the heat dissipation function, reducing the temperature of the circuit board body 1, and preventing the performance of electronic components from deteriorating or being damaged due to overheating. This improves the heat dissipation performance and working stability of the circuit board body 1. When it is necessary to remove the fan 404, pull the limit rod 406. The limit rod 406 slides, causing the guide block 408 to slide. The sliding of the guide block 408 causes the spring 409 to retract, and the limit rod 406 is no longer engaged with the limit hole 407. The mounting block 402 can then be removed from the guide rail 401, completing the removal of the fan 404. The engagement of the limit rod 406 with the guide rail 401 facilitates the quick installation of the fan 404 on the guide rail 401, improving installation efficiency and making it convenient to inspect or replace the fan 404.

[0025] In use, when the circuit board body 1 needs to be installed on the equipment, the mounting post 201 is inserted into the mounting hole of the equipment. Then, the lead screw 205 is inserted through the hexagonal sleeve. Rotating the lead screw 205 will cause the slide plate 204 to slide towards the slider 203. When the slide plate 204 slides, it drives the drive plate 208 to slide and will slide in cooperation with the guide rod 207. The guide rod 207 makes the slide plate 204 slide more smoothly. At the same time, the drive plate 208 drives the two sliders 203 to slide in opposite directions. The drive plate 208 will slide in cooperation with the guide plate 206. The guide plate 206 makes the drive plate 203 slide more smoothly. 08. Sliding is smoother. The slider 203 drives the rubber pad 202 to slide, making the rubber pad 202 abut against the inner wall of the equipment mounting hole, thus completing the fixation. The method of driving the rubber pad 202 to abut against the inner wall of the mounting hole by the sliding plate 204 avoids the stripping and other problems that are prone to occur in traditional bolt installation, improving the installation stability of the circuit board body 1 and ensuring the normal use of the equipment. When it is necessary to replace the mounting post 201 of different lengths, rotate the threaded ring 304 so that it is no longer threadedly connected to the mounting ring 301, and slide the mounting post 201 and the connecting block 302 out along the mounting ring 301, so that the mounting post 201 of different lengths can be installed. The installation is completed by attaching the mounting ring 301 and then threading the threaded ring 304 onto the mounting ring 301. The ball bearing 303 reduces the friction between itself and the threaded ring 304. By replacing the mounting post 201 with different lengths, it can adapt to installation requirements when a specific distance from the equipment is needed, thus improving the versatility of the circuit board body 1. When heat dissipation is required for the circuit board body 1, the heat is conducted to the heat sink 405, and the fan 404 is activated. The fan 404 removes the heat from the heat sink 405 and the circuit board body 1, achieving the heat dissipation function and reducing the temperature of the circuit board body 1. To prevent overheating from causing performance degradation or damage to electronic components, the heat dissipation performance and operational stability of the circuit board body 1 are improved. When it is necessary to disassemble the fan 404, pull the limiting rod 406. The limiting rod 406 slides, causing the guide block 408 to slide. The sliding of the guide block 408 causes the spring 409 to retract, and the limiting rod 406 is no longer engaged with the limiting hole 407. The mounting block 402 can then be removed from the guide rail 401, completing the disassembly of the fan 404. The engagement of the limiting rod 406 with the guide rail 401 facilitates the quick installation of the fan 404 on the guide rail 401, improving installation efficiency and making it convenient to inspect or replace the fan 404.
