Detailed implementation mode

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figure 1 , Figure 2 shown, a PCB circuit board includes a circuit board body 1, a pair of mounting seats 2, a support bar 3, a clamping block 4 and a hook 5.

[0029] As Figure 1 shown, the circuit board body 1 is arranged in a horizontal plate shape, and a plurality of heat dissipation fins 11 are arranged on the upper end surface of the circuit board body 1. The plurality of heat dissipation fins 11 are surrounded in a ring shape. A fan 12 is arranged on the upper end surface of the circuit board body 1 and located inside the heat dissipation fins 11. The fan 12 blows air out from the side wall.

[0030] Therefore, during the operation of the circuit board body 1, the heat dissipation of the circuit board body 1 can be realized through the heat radiation principle of the heat dissipation fins 11. At the same time, the fan 12 can directly blow the heat dissipation fins 11 to accelerate the dissipation of the heat on the heat dissipation fins 11. At the same time, it can also blow each component to improve the heat dissipation effect of the circuit board body 1.

[0031] As Figure 1 , Figure 3 shown, a pair of mounting seats 2 are horizontally arranged below the two ends of the circuit board body 1. A shock pad 6 is arranged on the lower end surface of the mounting seat 2 to increase the shock absorption effect. An adhesive layer 7 is arranged on the lower end surface of the shock pad 6 to quickly and firmly install and fix the mounting seat 2.

[0032] As Figure 1 , Figure 3 shown, the support bar 3 is vertically arranged on the mounting seat 2 and is used to support the circuit board body 1. The clamping block 4 is rotatably connected to one of the support bars 3 and is used to clamp one end of the circuit board body 1. The hook 5 is vertically arranged on the other support bar 3 and is used to penetrate and hook the other end of the circuit board body 1.

[0033] Therefore, when installing the circuit board body 1, the control clamping block 4 is turned upwards, and then one end of the circuit board body 1 is inserted into the clamping block 4. Subsequently, the circuit board body 1 is controlled to drive the clamping block 4 to rotate synchronously, so that the circuit board body 1 rotates to a horizontal state. At the same time, the hook 5 on the other support bar 3 penetrates through the circuit board body 1 to realize the clamping and fixing of the circuit board body 1. Then, the mounting seat 2 is bonded and fixed by using the adhesive layer 7 below the mounting seat 2, and the installation and use of the entire PCB circuit board can be realized.

[0034] When the circuit board body 1 needs to be disassembled and repaired, the hook 5 is pressed to disengage from the circuit board body 1, and then the circuit board body 1 can be controlled to drive the clamping block 4 to turn to a vertical state, and the circuit board body 1 can be disassembled and repaired. After the repair is completed, the circuit board body 1 is inserted into the clamping block 4 again, and then the circuit board body 1 is controlled to turn so that the hook 5 penetrates through the circuit board body 1, and the installation and fixation of the circuit board body 1 can be realized.

[0035] Therefore, by setting the circuit board body 1 with one end clamped and the other end clamped and fixed, the quick installation and fixation and disassembly and repair of the circuit board body 1 can be realized. No tools are required during the disassembly and assembly process, so it is convenient to install and disassemble and repair the PCB circuit board in a narrow space, improving the convenience during installation and repair.

[0036] Such as Figure 2 、 Figure 3 As shown, both inner walls of the clamping block 4 are arranged in a stepped surface shape, and a plurality of grooves 41 for the circuit board body 1 to be embedded are formed. A spring 51 is sleeved on the hook 5.

[0037] Therefore, by setting the grooves 41 on the clamping block 4 that can adapt to circuit board bodies 1 of different thicknesses, and setting the spring 51 on the hook 5 that can support the circuit board body 1, the clamping strip and the hook 5 can clamp and fix circuit board bodies 1 of different thicknesses, improving the practicability.

[0038] Such as Figure 3 、 Figure 4 As shown, a clamping strip 13 is arranged at one end of the circuit board body 1 close to the clamping block 4, and a clamping groove 42 for the clamping strip 13 to be embedded is arranged on the inner wall of the groove 41, so as to increase the stability between the circuit board body 1 and the clamping block 4 and ensure the structural strength of the connection position.

[0039] Such as Figure 3 、 Figure 4 As shown, a slide rail 31 is arranged on the lower end surface of the support bar 3, a sliding groove 21 for the slide rail 31 to slide is arranged on the mounting seat 2, and racks 8 that are mutually clamped are arranged on the lower end surface of the slide rail 31 and the bottom wall of the sliding groove 21.

[0040] Therefore, when installing and fixing the circuit board body 1, the support bar 3 can be pushed to drive the slide rail 31 to slide in the chute 21 of the mounting base 2, so as to realize the position adjustment of the circuit board body 1, meet different installation requirements. At the same time, when adjusting the position, the rack 8 which cooperate with each other can be used to realize clamping and fixing, so as to increase the stability of the circuit board body 1 after the position adjustment.

[0041] The specific embodiments are only explanations of the present invention, and they are not limitations to the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
