[0027] Specifically, if Figure 1As shown, when the current of the power supply body 2 is too high, the current sensor 3 will immediately sense it, and then disconnect the power supply body 2 through the processing module 11 and the switch module 12 to prevent the power supply body 2 from burning due to the input current being too high, thereby preventing safety problems. When the current of the power supply body 2 is overloaded, the information sending module inside the power supply body 2 will cause the alarm 10 to sound an alarm, thereby promptly reminding the user that the power supply body 2 is overloaded. Reminding the user of the power supply body 2 in time can facilitate the user to promptly repair the components inside the power supply body 2.

[0028] Embodiment 2: The two sides of the bottom end of the top plate 5 are fixedly connected with the fixed plate 4, and the side of the fixed plate 4 close to the outside is provided with a movable plate 13, a spring 14 is fixedly connected between the fixed plate 4 and the movable plate 13, and a damper 19 is provided inside the spring 14. The side of the movable plate 13 close to the outside is fixedly connected with a limit card rod 18, and the top ends of the two sides of the interior of the shell 1 are provided with a limit card groove 17. The top end of the movable plate 13 is fixedly connected with a pull rod 15, and reserved grooves 16 are provided on both sides of the interior of the top plate 5. The limit card rod 18 is embedded in the inside of the limit card groove 17. The top plate 5 is fixed by the limit card groove 17 and the limit card rod 18. The pull rod 15 is provided inside the reserved groove 16, and the pull rod 15 slides inside the reserved groove 16.

[0029] Specifically, if Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, when the top plate 5 needs to be installed, the pull rod 15 is pulled, and the pull rod 15 drives the movable plate 13 to squeeze the spring 14, and then the top plate 5 is placed on the top of the shell 1. The spring 14 will use its own elasticity to make the movable plate 13 drive the limiting card rod 18 to be embedded in the inside of the limiting card slot 17, so that the top plate 5 can be fixed to prevent the top plate 5 from accidentally detaching from the top of the shell 1. When the top plate 5 needs to be disassembled to repair the components inside the shell 1, the pull rod 15 is pulled, and the pull rod 15 drives the limiting card rod 18 to detach from the inside of the limiting card slot 17 through the movable plate 13.

[0030] Example 3: The interior of the support frame 6 is fixedly connected to a mounting plate 7, fans 8 are installed on both sides of the bottom end of the mounting plate 7, a movable plate 13 is provided at the top end of the interior of the support frame 6, a connecting plate 9 is fixedly connected to the front end of the movable plate 13, the top ends of both sides of the interior of the support frame 6 are fixedly connected to the right support block, the movable plate 13 is provided at the top end of the movable plate 13 support block, the connecting plate 9 is provided at the front end of the support frame 6, two groups of fans 8 are provided, and the fans 8 are symmetrically distributed about the vertical center line of the mounting plate 7;

[0031] Specifically, if Figure 1 、 Figure 2 and Figure 3As shown, the fan 8 is started, and the fan 8 blows air to the interior of the shell 1 to cool down the interior of the shell 1, thereby preventing the temperature inside the shell 1 from being too high and causing damage to the components inside the shell 1. When the fan 8 is working, the movable plate 13 can absorb moisture in the air to prevent moisture from entering the interior of the shell 1 and affecting the components inside the shell 1. When the movable plate 13 needs to be replaced, the connecting plate 9 is pulled, and the connecting plate 9 drives the movable plate 13 to separate from the interior of the support frame 6, thereby facilitating the replacement of the movable plate 13.

[0032] Working principle: When the utility model is in use, it is necessary to pull the pull rod 15 when installing the top plate 5. The pull rod 15 drives the movable plate 13 to squeeze the spring 14, and then the top plate 5 is placed on the top of the shell 1. The spring 14 will use its own elasticity to make the movable plate 13 drive the limit card rod 18 to be embedded in the inside of the limit card slot 17, so that the top plate 5 can be fixed to prevent the top plate 5 from accidentally detaching from the top of the shell 1. When the current of the power supply body 2 is too high, the current sensor 3 will immediately sense it, and then the power supply body 2 will be disconnected through the processing module 11 and the switch module 12 to prevent the power supply body 2 from burning due to excessive input current and causing safety problems. When the current of the power supply body 2 is overloaded, the information sending module inside the power supply body 2 will cause the alarm 10 to sound an alarm, so that the user can promptly remind the power supply. When the main body 2 is overloaded, the fan 8 is started when the power supply main body 2 is working. The fan 8 blows air to the inside of the shell 1 to cool down the inside of the shell 1, thereby preventing the temperature inside the shell 1 from being too high and causing damage to the components inside the shell 1. When the fan 8 is working, the movable plate 13 can absorb moisture in the air to prevent moisture from entering the inside of the shell 1 and affecting the components inside the shell 1. When the movable plate 13 needs to be replaced, the connecting plate 9 is pulled, and the connecting plate 9 drives the movable plate 13 to disengage from the inside of the support frame 6, thereby facilitating the replacement of the movable plate 13. When the top plate 5 needs to be removed to repair the components inside the shell 1, the pull rod 15 is pulled, and the pull rod 15 drives the limit card rod 18 to disengage from the inside of the limit card slot 17 through the movable plate 13, thereby making the top plate 5 lose its fixation. If the top plate 5 loses its fixation, the top plate 5 can be removed.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
