[0026] A convenient disassembly and assembly mechanism is provided, and the convenient disassembly and assembly mechanism includes fixed connection components arranged on the outer surfaces of circuit board 1 101, circuit board 2 102 and circuit board 3 103.

[0027] In order to facilitate the fixed installation of the PCB circuit board main body 100 after being engaged through the fixed connection component, in this embodiment, preferably, the fixed connection component includes a mounting plate 1011 arranged on the outer surfaces of circuit board 1 101, circuit board 2 102 and circuit board 3 103, and fixing plates 1012 are integrally formed at both ends of the mounting plate 1011.

Circuit board 1 101, circuit board 2 102 and circuit board 3 103 can be stacked and placed and fixedly installed in the interior of the mounting plate 1011 through the card slots 1014, and the heat dissipation of the lower surface is processed by the heat dissipation groove 1013 when used after installation.

[0028] In order to facilitate the clamping of circuit board 1 101, circuit board 2 102 and circuit board 3 103 in the interior of the card slot 1014 and then reinforce the installation through the elastic locking assembly, in this embodiment, preferably, the elastic locking assembly includes three limit slots 1016 opened on both sides of the end of the installation plate 1011, and the internal limit of the limit slot 1016 is limited by a clamping head 1018, and an elastic block 1017 is provided at the connection between the end of the clamping head 1018 and the interior of the limit slot 1016. The deformation of the elastic block 1017 causes the clamping head 1018 to be elastically connected to the interior of the limit slot 1016, which facilitates elastic clamping installation. Clamping holes 1019 are opened on both sides of the ends of circuit board 101, circuit board 2 102 and circuit board 3 103, and the end of the clamping head 1018 is clamped with the interior of the clamping hole 1019 until the clamping head 1018 is elastically clamped in the interior of the clamping hole 1019 for reinforced installation.

[0029] In order to facilitate the opening or closing of the clamping head 1018 by toggling the adjustment component and facilitate the disassembly and adjustment operations, in this embodiment, preferably, the toggling adjustment component includes three threaded levers 1015 sliding on the sides of the two ends of the mounting plate 1011, and the ends of the threaded levers 1015 are rotationally connected to the sides of the clamping head 1018 through a threaded structure, so that the clamping head 1018 can be adjusted by holding the threaded lever 1015 during the disassembly and assembly operations, and the threaded lever 1015 can be rotated to reinforce the installation of the clamping head 1018 after the clamping installation.

[0030] The protective mechanism includes a protective component arranged on the upper surface of the circuit board 3 103. Buffer connection components are provided at the connection points between the two ends of the protective component and the end of the fixed connection component. When the PCB circuit board body 100 is fixedly installed and used, the protective mechanism can provide buffer protection for the upper surface of the PCB circuit board body 100, making it less likely to be damaged when impacted, thereby improving the buffer protection effect of the PCB circuit board body 100 during installation and use.

[0031] In order to facilitate buffering and protecting the upper surface of the PCB circuit board body 100 through the protective component and not easily cause damage when it is hit, in this embodiment, preferably, the protective component includes a protective mesh plate 1031 arranged on the upper surface of the circuit board three 103 and located inside the mounting plate 1011, and the protective mesh plate 1031 is a rectangular structure.

[0032] In order to facilitate buffering and protecting the protective mesh 1031 when it is hit by a buffer connection assembly, in this embodiment, preferably, the buffer connection assembly includes five slide grooves 1033 opened on the inner sides of both ends of the mounting plate 1011, and a slider 1032 is provided at the inner top of the slide groove 1033. The end of the slider 1032 is fixed to the end of the protective mesh 1031 by screws, and a buffer spring 1034 is provided at the connection between the bottom end of the slider 1032 and the inner bottom end of the slide groove 1033. When the protective mesh 1031 is hit, the buffer spring 1034 can be deformed to drive the slider 1032 to buffer inside the slide groove 1033, thereby driving the protective mesh 1031 to buffer, which is convenient for buffering and protecting the protective mesh 1031 and reducing the impact.

[0033] The working principle and use process of the present invention are as follows: when installing the multi-layer gold-plated PCB circuit board, the threaded lever 1015 can be held to move the card hole 1019 to embed it into the inner part of the limit groove 1016, and the circuit board 1 101, the circuit board 2 102 and the circuit board 3 103 are stacked and placed, and the circuit board 1 101, the circuit board 2 102 and the circuit board 3 103 are clamped into the inner part of the installation plate 1011 through the card slot 1014. After the clamping and installation, the threaded lever 1015 is loosened, and the elastic block 1017 is deformed to drive the clamp head 1018 to elastically clamp into the inner part of the card hole 1019, and the threaded lever 1015 is rotated to reinforce the clamp head 1018, thereby fixing the circuit board 101, the circuit board 2 102 and the circuit board 3 101. 3 is fixed inside the mounting plate 1011. After fixed installation, the mounting plate 1011 is closed at the installation position inside the electronic product, and the screws are inserted into the interior of the fixing plate 1012 to fix the mounting plate 1011. Thus, the PCB circuit board body 100 is fixed and installed through the mounting plate 1011. The fixed installation is convenient. When in use, heat is dissipated through the heat dissipation groove 1013 at the bottom, which is not easy to cause installation extrusion damage. When the PCB circuit board body 100 is damaged after long-term use, the opposite operation can be directly removed from the inside of the mounting plate 1011 by removing the circuit board 1 101, the circuit board 2 102 and the circuit board 3 103. The disassembly and assembly operation is convenient, which improves the convenience of disassembly and assembly of the PCB circuit board body 100 in the fixed installation and use.

[0034] Finally, when the PCB circuit board body 100 is fixedly installed inside the electronic product for use, when the electronic product is carried and touched and the surface of the PCB circuit board body 100 is touched, it directly touches the surface of the protective mesh plate 1031. When the protective mesh plate 1031 is touched and subjected to force, the buffer spring 1034 is driven to deform under the force. The deformation of the buffer spring 1034 drives the slider 1032 to slide inside the slide groove 1033, thereby driving the slider 1032 to buffer through the slider 1032, so that the protective mesh plate 1031 can provide surface buffering protection for the circuit board 103, so that the PCB circuit board body 100 can be easily buffered and protected after installation, and it is not easy to be damaged when the electronic product is carried and hit after installation, thereby improving the buffering and protection effect of the PCB circuit board body 100 during installation and use.
