[0016] (1) By setting a positioning frame, positioning pressure plate, cavity, positioning pin, support plate, positioning slot, movable block, ejection spring, fixing pin and positioning hole, the positioning frame is first placed on the top of the support plate during assembly, and the fixing pin on the top of the support plate is inserted into the positioning hole. Then the positioning pressure plate is inserted into the mounting frame. The ejection spring inside the cavity can eject the positioning pin through the movable block and insert it into the positioning slot. Thus, the positioning pressure plate is positioned by the positioning pin.

Positioning slots 16 are opened at both ends of the top of both sides of the mounting frame 1.

[0029] The positioning pin 8 passes through one side of the positioning plate 6 and extends into the positioning slot 16, and the positioning pin 8 is movably connected to the positioning slot 16.

[0030] The support plate 9 is movably connected to the positioning frame 2, and the fixing pin 20 is movably connected to the positioning hole 21;

[0031] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, during assembly, the positioning frame 2 is first placed on the top of the support plate 9, and the fixing pin 20 on the top of the support plate 9 is inserted into the positioning hole 21. Then, the positioning pressure plate 6 is inserted into the mounting frame 1. The ejection spring 19 inside the cavity 7 can push out the positioning pin 8 through the movable block 17 and insert it into the positioning slot 16, thereby positioning the positioning pressure plate 6 through the positioning pin 8. The positioning pressure plate 6 presses on the top of the positioning frame 2 and can cooperate with the support plate 9 to fix the positioning frame 2 and the circuit board body 3, thus making assembly convenient.

[0032] A heat-conducting plate 4 is fixedly connected to the top of the positioning frame 2, and a heat dissipation fin 5 is fixedly connected to the bottom of the heat-conducting plate 4. Ventilation openings 13 are provided at both ends of the mounting frame 1.

[0033] Ventilation 13 is connected to the interior of mounting frame 1, and heat conduction plate 4 is movably connected to circuit board body 3;

[0034] Specifically, such as Figure 1 and Figure 5As shown, after the structure is assembled, the heat-conducting plate 4 inside the positioning frame 2 is attached to the bottom of the circuit board body 3 and can absorb the heat generated by the circuit board body 3 during operation. After absorbing the heat, the heat is transferred to the heat dissipation fins 5 at the bottom. The ventilation openings 13 at both ends of the mounting frame 1 can form a through air channel. When the external air flows through the ventilation openings 13 and passes through the interior of the mounting frame 1, it can exchange heat with the heat dissipation fins 5, thereby quickly dissipating heat and cooling the circuit board body 3 through the heat-conducting plate 4, thus effectively dissipating heat for the circuit board body 3.

[0035] The bottom of the mounting frame 1 has bottom grooves 22 on both sides. The bottom grooves 22 are movably connected to the interior of the bottom grooves 22. The top of the movable mounting plate 10 has a mounting hole 18 on one side. The bottom of both ends of the mounting frame 1 has sliding grooves 11 on both sides.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, before installing the structure, after rotating the positioning nut 14 to disengage it from one end of the mounting frame 1, the movable mounting plate 10 can be pulled to adjust the position of the two movable mounting plates 10. According to the reserved mounting through hole spacing, the two sets of mounting holes 18 are adjusted to a suitable spacing.

The limiting slider 12 fits inside the slide groove 11 to limit the movable mounting plate 10 and prevent the movable mounting plate 10 from shaking, thus realizing the ability to adapt to different installation structures.

[0039] Working principle: Before installing this structure, rotate the positioning nut 14 to disengage it from one end of the mounting frame 1. Then, pull the movable mounting plate 10 to adjust the position of both sides of the movable mounting plate 10. Adjust the two sets of mounting holes 18 to a suitable distance according to the reserved mounting through hole spacing. After the distance is appropriate, rotate the positioning nut 14 to tighten it, thereby positioning the movable mounting plate 10 through the threaded rod 15. The limiting slider 12 fits inside the slide groove 11 to limit the movable mounting plate 10 and prevent it from shaking. During assembly, first place the positioning frame 2 on the top of the support plate 9 and insert the fixing pin 20 on the top of the support plate 9 into the positioning hole 21.

The positioning plate 6 presses on the top of the positioning frame 2 and can cooperate with the support plate 9 to fix the positioning frame 2 and the circuit board body 3. After the structure is assembled, the heat-conducting plate 4 inside the positioning frame 2 is attached to the bottom of the circuit board body 3 and can absorb the heat generated by the circuit board body 3 during operation. After absorbing the heat, the heat is transferred to the heat dissipation fins 5 at the bottom. The ventilation openings 13 at both ends of the mounting frame 1 can form a through air channel. When the external air flows through the ventilation openings 13 and passes through the interior of the mounting frame 1, it can exchange heat with the heat dissipation fins 5, thereby quickly dissipating heat and cooling the circuit board body 3 through the heat-conducting plate 4.
