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.

[0030] See also Figures 1 to 6 , the utility model provides a technical solution:

[0032] The dustproof heat dissipation protection mechanism 3 includes a mounting frame 31, a heat dissipation fan group 32, a slot 33, a dust filter 34, a locking slot 35 and a locking plate 36. The mounting frame 31 is fixedly connected to the side wall of the protection box 1, the heat dissipation fan group 32 is bolted to the side wall of the mounting frame 31, the slot 33 is opened at the top of the mounting frame 31, the dust filter 34 is movably arranged inside the slot 33, the locking slot 35 is opened on the side wall of the mounting frame 31, and the locking plate 36 is movably arranged inside the locking slot 35. The side wall of the locking plate 36 contacts the dust filter 34.

[0033] Specifically, Figure 3 and Figure 6 As shown, the maintenance mechanism 5 includes an inspection cover 51, a limiting groove 52 and a limiting strip 53. The inspection cover 51 is arranged on the top of the protection box 1, two limiting grooves 52 are opened on the side wall of the protection box 1, and two limiting strips 53 are arranged at both ends of the inspection cover 51. The limiting strips 53 are movably connected with the limiting grooves 52.

[0034] Specifically, Figure 6As shown, a plurality of ventilation grooves 6 are provided on both side walls of the protection box 1 , and a positioning groove 7 is provided on both side walls of the protection box 1 , and a filter screen plate 8 is bolted inside the positioning groove 7 .

[0035] Specifically, Figure 5 As shown, a blocking plate 9 is bolted to one end of the opening of the protection box 1 , and the blocking plate 9 is movably connected to the power source body 2 .

[0036] Specifically, Figure 3 As shown, an observation port 13 is provided in the middle of the inspection cover 51 , and a transparent glass 14 is inlaid in the middle of the observation port 13 .

[0037] When in use, first, the cooling fan group 32 is connected to the internal air supply of the power box protection box 1, which can speed up the gas circulation inside the protection box 1 and realize the rapid heat dissipation of the power supply body 2. In this process, the dust filter 34 can filter the gas entering the protection box 1 to prevent external dust from entering the protection box 1 and adhering to the power supply body 2. When the power supply body 2 is in normal operation, the natural heat dissipation of the power supply body 2 can be realized through the ventilation groove 6. The ventilation groove 6 can be dust-proofed by the filter plate 8. When the dust filter 34 is replaced and maintained, the locking plate 36 can be pulled out of the locking groove 35 to release the limit protection of the dust filter 34. The sliding connection between the limit strip 53 and the limit groove 52 facilitates the disassembly and assembly of the inspection cover 51. At the same time, the observation port 13 and the transparent glass 14 facilitate the operation of the power supply body 2 inside the protective box 1. In this way, dust filtering protection can be performed between the heat dissipation fan group 32 and the protective box 1, and external dust can be prevented from entering the interior of the protective box 1 through the heat dissipation fan group 32. At the same time, the airflow entering the protective box 1 can be dust-filtered, and the dust filter 34 can be quickly replaced, which can speed up the air circulation inside the protective box 1 and quickly dissipate the heat of the power supply body 2 inside the protective box 1, thereby improving the protection effect of the power supply body 2.

[0038] Specifically, Figure 5 and Figure 6 As shown, the connecting wire clamping protection mechanism 4 includes a bottom plate 41, a through slot 42, a pressure plate 43, a groove 44, a positioning screw 45 and an adjustment slot 46. One side of the protection box 1 is opened, the bottom plate 41 is fixedly connected to the inner wall of the protection box 1, the through slot 42 is opened on the side wall of the protection box 1, the pressure plate 43 is movably arranged inside the through slot 42 and is movably connected to the bottom plate 41, a plurality of grooves 44 are respectively opened on the side walls of the bottom plate 41 and the pressure plate 43, the positioning screw 45 is threadedly connected to the side wall of the protection box 1, the adjustment slot 46 is opened on the side wall of the pressure plate 43, and the positioning screw 45 is movably connected to the adjustment slot 46.

[0039] Specifically, Figure 5As shown, an anti-skid pad 10 is bolted to the side wall of the groove 44, and the anti-skid pad 10 is arranged in an arc shape.

[0040] Specifically, Figure 5 As shown, two connection blocks 11 are fixedly connected to the top of the pressing plate 43 , and a pull rod 12 is fixedly connected to the middle of the two connection blocks 11 .

[0041] During use, after the connecting wire is connected to the power supply body 2, the pressure plate 43 is pushed downward to move. At this time, the connecting wire can be compressed and protected by the groove 44, and the pressure plate 43 can be positioned by the positioning screw 45. The clamping force of the pressure plate 43 on the connecting wire can be adjusted by the setting of the adjustment groove 46. In this way, the connecting wire connected to the power supply body 2 can be compressed and positioned to prevent the connecting wire from being broken and falling off from the power supply body 2 due to external force pulling on the connecting wire, and at the same time, the clamping force on the connecting wire can be adjusted.

[0042] By adopting the above technical solution, the problem of the existing switching power supply protection device that external dust can easily enter the interior of the protection device through the cooling fan, the problem that the airflow entering the interior of the protection device cannot be dust-proof filtered when the switching power supply is dissipating heat, and the problem that the connecting wires of the switching power supply cannot be compressed and protected is solved. The existing switching power supply is easily pulled by external force when in use, causing the connecting wires to break.

[0043] Working principle: When the present application is in use, first, after the connecting wire is connected to the power source body 2, the pressing plate 43 is pushed downward to move. At this time, the connecting wire can be pressed and protected by the groove 44, and the pressing plate 43 can be positioned by the positioning screw 45. The pressing force of the pressing plate 43 on the connecting wire can be adjusted by setting the adjustment groove 46. The cooling fan group 32 is connected to the internal air supply of the power source box protection box 1, which can speed up the gas circulation inside the protection box 1 and realize the rapid heat dissipation of the power source body 2. In this process, the dust filter 34 can filter the gas entering the protection box 1. The invention can prevent external dust from entering the protection box 1 and adhering to the power supply body 2. The power supply body 2 can achieve natural heat dissipation through the ventilation groove 6 when operating normally. The ventilation groove 6 can be protected from dust through the filter plate 8. When the dust filter 34 is replaced and maintained, the locking plate 36 can be pulled out of the locking groove 35 to release the limit protection of the dust filter 34. The limit bar 53 is slidably connected with the limit groove 52 to facilitate the disassembly and assembly of the maintenance cover 51. At the same time, the operation of the power supply body 2 inside the protection box 1 can be easily observed through the observation port 13 and the transparent glass 14.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
