[0029] 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.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-4 As shown, this utility model is a multilayer circuit board that is easy to install, comprising:

[0032] The main component includes the shelf body 11;

[0033] Multiple layered board bodies 11 are assembled by splicing to form a multi-layered circuit board;

[0034] The assembly components include a side seat 21, a mounting block 22, a limiting hole 23, a locking block 24, a tension spring 25, and a mounting groove 27.

[0035] The side seat 21 is fixedly connected to the side end of the bottom shelf body 11. The mounting groove 27 is opened inside the side seat 21. The limiting hole 23 is connected to the side of the mounting groove 27. The locking block 24 is embedded in the limiting hole 23. The tension spring 25 is fixedly connected between the side seat 21 and the locking block 24. The mounting block 22 is fixedly connected to the side end of the upper shelf body 11.

[0036] The side seat 21 is used to limit the installation of the upper shelf body 11. The mounting groove 27, together with the mounting block 22, allows the shelf bodies 11 to be stacked. The limiting hole 23 is used to limit the installation of the locking block 24. The locking block 24 is used to intercept the limiting installation block 22 to ensure that the shelf body 11 is firmly installed and positioned. The tension spring 25 has a pulling effect to ensure that the locking block 24 is stably limited and intercepted.

[0037] The mounting block 22 and the mounting groove 27 are connected by a sliding joint structure, and the side end of the mounting block 22 is in contact with the surface of the locking block 24.

[0038] The sliding connection structure facilitates the disassembly, inspection, and replacement of multi-layer circuit boards, making the assembly of the device simpler and more convenient.

[0039] The side seat 21 has a groove 26 corresponding to the tension spring 25 on its surface, the side end of the locking block 24 has a beveled structure, and the mounting block 22 is tangent to the locking block 24;

[0040] The groove 26 is used to accommodate the tension spring 25 to shorten the distance between the locking block 24 and the side seat 21 and reduce the overall space. The inclined structure allows the mounting block 22 to be inserted into the mounting groove 27 and contact the cut surface of the locking block 24, which can be pushed open directly, making installation simpler and more convenient.

[0041] The side end of the mounting block 22 is connected to a receiving groove 281, and a spring 28 is provided inside the receiving groove 281;

[0042] After the latch 24 is removed from the side of the mounting block 22, the spring 28 in the receiving groove 281 returns to its original state, which can pop out the shelf body 11 for easy disassembly.

[0043] Working principle: Multiple layer boards 11 can be stacked and connected to form a multi-layer circuit board;

[0044] The mounting block 22 slides into the side seat 21 through the mounting groove 27. The mounting block 22 is inserted into the mounting groove 27 and contacts the cut surface of the locking block 24, which can directly push it open. Then, under the pulling force of the tension spring 25 in the groove 26, the locking block 24 moves and resets within the limiting hole 23. The locking block 24 forms an interception at the side end of the mounting block 22, and the multi-layer plate body 11 can be stacked and fixed. Under the elastic force of the spring 28 inside the receiving groove 281, the mounting block 22 can drive the upper layer plate body 11 to pop out directly.

[0045] This step facilitates the disassembly and assembly of circuit board layers, making maintenance easier and improving the device's performance.

[0046] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes a mounting component;

[0047] The mounting components include a fixed base 31, a through groove 32, a second spring 33, a control block 34, a fixing block 35, a bolt seat 36, a fixing hole 37, and a slide 38;

[0048] The fixed seat 31 is fixedly connected to the surface of the side seat 21, the slide groove 38 is opened inside the fixed seat 31, the bolt seat 36 is embedded inside the slide groove 38, the fixing hole 37 is opened inside the bolt seat 36, the through groove 32 is connected to the side end of the slide groove 38, the fixing block 35 is embedded inside the through groove 32, the second spring 33 is fixedly connected to the surface of the fixing block 35, and the control block 34 is fixedly connected to the top of the fixing block 35.

[0049] The mounting base 31 is used to install the mounting base 31. The sliding groove 38, in conjunction with the bolt seat 36, allows for free adjustment of the position of the fixing hole 37. The through groove 32 is used to accommodate the fixing block 35. The fixing block 35 is used to engage the fixing bolt seat 36. The second spring 33 is used to press the fixing block 35. The control block 34 is used to control the position movement of the fixing block 35.

[0050] Both the bolt seat 36 and the slide 38 have a cross-shaped structure, and the surface of the bolt seat 36 is in close contact with the inner wall of the slide 38.

[0051] The cross-shaped structure ensures a stable and tight connection between the bolt seat 36 and the slide groove 38, making the installation and positioning of the bolt seat 36 driving the device more secure.

[0052] The side of the fixing block 35 and the side of the bolt seat 36 are both toothed, and the fixing block 35 and the bolt seat 36 mesh with each other. The control block 34 has an n-shaped structure.

[0053] The toothed structure allows the fixing block 35 and the bolt seat 36 to mesh tightly, making it easy to adjust the position of the bolt seat 36; the n-shaped structure makes it easy to control the movement of the fixing block 35.

[0054] Working principle: The moving control block 34 drives the fixed block 35 to move within the through groove 32. After the fixed block 35 separates from the bolt seat 36, the position of the bolt seat 36 can be adjusted according to the actual installation point under the sliding connection between the bolt seat 36 and the slide groove 38. When the control block 34 is released, the fixed block 35 resets and engages with the bolt seat 36 under the elastic force of the second spring 33 to complete the positioning. The bolt passes through the fixing hole 37 and engages with the fixing point to complete the installation and fixing of the multilayer circuit board.

[0055] This step allows for adjustable bolt fixing points, simplifies operation, and improves the installation adaptability of the device.
