[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 The utility model provides an embodiment: a printed circuit board with a dustproof structure, comprising a shell 1, an outer wall of the shell 1 is provided with a dust cover 2, a slider 3 is slidably connected to the inside of the shell 1, a limit rod 7 is slidably connected to the inside of the slider 3, an outer wall of the limit rod 7 is fixedly connected to the outer wall of the shell 1, a spring 2 8 is sleeved on the outer wall of the limit rod 7, one end of the spring 2 8 is fixedly connected to the outer wall of the slider 3, the other end of the limit rod 7 is fixedly connected to the inner wall of the shell 1, a block 5 is provided on the inner wall of the slider 3, and the block 5 A connecting rod 4 is fixedly connected to the interior thereof, the outer wall of the connecting rod 4 is slidably connected to the inner wall of the outer shell 1, the inner wall of the slider 13 is slidably connected to the slider 29, the outer wall of the slider 29 is fixedly connected to the connecting block 10, the outer wall of the connecting block 10 is slidably connected to the outer wall of the slider 3, a spring 16 is arranged inside the outer shell 1, the top end of the spring 16 is fixedly connected to the outer wall of the connecting rod 4, the bottom end of the spring 16 is fixedly connected to the inner wall of the outer shell 1, the outer wall of the connecting rod 4 is fixedly connected to the dust cover 2, and the inner wall of the dust cover 2 is arranged with an adjusting component;

[0025] Specifically, the circuit board 12 is installed inside the shell 1. This step is to protect the electronic components and prevent dust and other impurities from entering the interior of the device. After the circuit board 12 is installed, the connecting block 10 is pushed onto the slider 3. This step is to prepare to start the disassembly device. Then, the slider 3 is pressed. In the process of pressing the slider 3, the connecting block 10 will push the spring 2 8 to contract. The contraction of the spring 2 8 provides power for the subsequent disassembly process. At the same time, the limit rod 7 limits the spring 2 8 and the slider 3 to prevent the slider 3 from deviating during movement, thereby ensuring the stability of the disassembly process. Next, the restriction on the card block 5 is relaxed by the moving slider 3. Under the push of the spring 6, the card block 5 can be smoothly separated from the shell 1, thereby achieving the purpose of removing the dust cover 2 from the top of the shell 1. In this way, the disassembly process of the dust cover 2 becomes very convenient. Through this design, the installation, disassembly and cleaning of the dust cover 2 can be easily achieved.

[0026] Reference Figure 4-5The adjustment component includes a sliding cover 11, the outer wall of the sliding cover 11 is slidably connected to the inner wall of the dust cover 2, and a circuit board 12 is arranged inside the housing 1; a fixing block 13 is fixedly connected to the outer wall of the sliding cover 11, and the outer wall of the fixing block 13 is slidably connected to the inner wall of the dust cover 2; a button 15 is slidably connected to the inner wall of the fixing block 13, and the outer wall of the button 15 is fixedly connected to the connecting plate 14; a push spring 16 is arranged inside the fixing block 13, and one end of the push spring 16 is fixedly connected to the inner wall of the fixing block 13. The other end of the push spring 16 is fixedly connected to the outer wall of the connecting plate 14; the interior of the fixed block 13 is provided with a push spring 2 17, one end of the push spring 2 17 is fixedly connected to the inner wall of the fixed block 13, and the other end of the push spring 2 17 is fixedly connected to a sliding ball 18; the outer wall of the sliding ball 18 is fixedly connected to the outer wall of the connecting plate 14, and the outer wall of the sliding ball 18 is fixedly connected to a card bead 19; the outer wall of the card bead 19 is slidably connected to the inner wall of the fixed block 13, and the outer wall of the card bead 19 is arranged inside the dust cover 2;

[0027] Specifically, the button 15 plays a vital role as the starting device of the entire mechanical system. It triggers the expansion and contraction of the push spring 16 by driving the movement of the connecting plate 14. This process seems simple, but it actually contains precise mechanical principles. The connecting plate 14 acts as an intermediary to transmit the movement of the button 15 to the push spring 2 17 and the sliding ball 18. In this process, the design of the connecting plate 14 must take into account stability and flexibility to ensure smooth transmission of force without loss of kinetic energy. The operation of the push spring 2 17 and the sliding ball 18 adds more possibilities to the entire mechanical system. The sliding ball 18 is driven by the push spring 2 17. Under the movement, long-distance movement can be achieved, thereby driving the card bead 19 to move downward. This design makes the movement of the mechanical system smoother and reduces wear. The movement of the card bead 19 directly affects the release of the dust cover 2. When the card bead 19 moves downward, the dust cover 2 is released, thereby achieving effective protection for the mechanical equipment. Finally, the push of the fixed block 13 causes the sliding cover 11 inside the dust cover 2 to slide. This design allows the size of the vent hole of the dust cover 2 to be adjusted, which not only ensures the ventilation inside the equipment, but also avoids dust from entering, further improving the operating efficiency and service life of the mechanical equipment.

[0028] Working principle: When it is necessary to use a printed circuit board with a dustproof structure, install the circuit board 12 inside the housing 1, push the connecting block 10 onto the slider 3, and then press the slider 3 to squeeze the spring 28 through the slider 3 to shrink the spring 28. At the same time, the spring 28 and the slider 3 are limited by the limiting rod 7 to prevent the slider 3 from deviating during movement. Then, the restriction on the card block 5 is relaxed by the moving slider 3, so that the card block 5 can be separated from the housing 1 under the push of the spring 6, so that the dust cover 2 can be removed from the top of the housing 1, thereby facilitating the removal of the dust cover 2. The dust cover 2 is disassembled to facilitate installation, disassembly and cleaning. After the circuit board 12 is installed on the housing 1, the dust cover 2 is installed on the housing 1, and the button 15 is pressed to drive the connecting plate 14 and the push spring 1 16 to move through the button 15, thereby driving the push spring 2 17 and the sliding ball 18 to operate through the connecting plate 14, and driving the card bead 19 to move downward through the sliding ball 18, thereby releasing the dust cover 2, and then pushing the fixing block 13, thereby driving the sliding cover 11 inside the dust cover 2 to slide through the fixing block 13, thereby achieving the effect of adjusting the size of the vent hole of the dust cover 2.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
