[0023] like Figures 1 to 5As shown, the AC / DC conversion control box of this embodiment includes a bottom plate 1, a mounting plate 2 is installed on one side of the upper end of the bottom plate 1, a plurality of interfaces 3 are arranged at one end of the mounting plate 2, a back plate 4 is installed on the upper end of the bottom plate 1 on one side of the mounting plate 2, an AC / DC conversion circuit is installed on the upper end of the bottom plate 1 between the mounting plate 2 and the back plate 4, a protective shell 5 is installed above the back plate 4, connecting rods 6 are installed at the front and rear parts above the mounting plate 2 and the back plate 4, and the surface of the connecting rod 6 is located inside the protective shell 5. The top end is installed with a movable block 7, and the surface of the connecting rod 6 between the movable block 7 and the back plate 4 is installed There is an elastic spring 8, and the protective shell 5 can slide on the surface of the connecting rod 6 under the action of the movable block 7. The AC-DC conversion circuit under the protective shell 5 can be exposed by sliding, which is convenient for troubleshooting the AC-DC conversion circuit, and there is no need to frequently disassemble the protective shell 5, which effectively improves the maintenance efficiency. A fixing component is installed on the upper end of the base plate 1 on one side of the mounting plate 2 under the connecting rod 6. The fixing component is used to limit the protective shell 5 to prevent the protective shell 5 from accidentally moving when protecting the AC-DC conversion circuit.

[0024] Specifically, the fixing assembly includes a mounting seat 901, a mounting tube 902, an elastic spring 903, a pull rod 904, a fixing rod 905 and a movable plate 906. The mounting seat 901 is installed on the upper end of the bottom plate 1 on one side of the mounting plate 2 below the connecting rod 6, and the mounting tube 902 is installed on the upper end. The fixing rod 905 is installed on the upper end of the mounting tube 902 through a through hole. The movable plate 906 is installed inside the mounting tube 902 below the fixing rod 905, and the movable plate 906 is installed below the mounting plate 906. An elastic spring 903 is installed inside the tube 902, and a pull rod 904 is installed at the lower end of the movable plate 906 inside the elastic spring 903. The fixed rod 905 limits the movable block 7 under the pushing action of the elastic spring 903 and the movable plate 906, so as to fix the protective shell 5. The movable plate 906 is moved by pulling the pull rod 904, and the movable plate 906 drives the fixed rod 905 to move downward. At the same time, the movable plate 906 compresses the elastic spring 903 to release the limit on the movable block 7.

[0025] Furthermore, a slope 10 is arranged near the edge above one end of the fixing rod 905 close to the back plate 4. With the setting of the slope 10, when the fixing rod 905 is used to limit the movable block 7, there is no need to pull the pull rod 904, and the movable block 7 can push the fixing rod 905.

[0026] Furthermore, a placement groove 11 is arranged at the lower end of the base plate 1 below the pull rod 904, and the lower end of the pull rod 904 extends into the placement groove 11. A rotating plate 12 is hingedly installed at the lower end of the pull rod 904, and a handle 13 is commonly installed at one end of the two rotating plates 12. The placement groove 11 is used to place the handle 13. By rotating the handle 13 and pulling the handle 13, the handle 13 can pull the two pull rods 904 at the same time, so as to control the two fixed rods 905 to move downward.

[0027] Furthermore, a vertical rod 14 is installed at the top of the placement groove 11 on one side of the handle 13, and a clamping plate 15 is slidably installed on the surface of the vertical rod 14 through a through hole. An elastic spring three 16 is installed on the surface of the vertical rod 14 between the clamping plate 15 and the placement groove 11. The elastic spring three 16 is used to push the clamping plate 15, and the clamping plate 15 is used to lock the handle 13 to prevent the handle 13 from rotating accidentally when it is stored.

[0028] Furthermore, locking bolts 17 are installed on the opposite end surfaces of the movable block 7 through screw holes, and one end of the locking bolts 17 extends to the connecting rod 6. The locking bolts 17 are used to lock the position of the movable block 7, which is convenient for fixing the position of the protective shell 5 and facilitating troubleshooting of the AC-DC conversion circuit.

[0029] The method of using this embodiment is as follows: when the AC / DC conversion control box is used normally, the protective shell 5 protects the AC / DC conversion circuit on the bottom plate 1, and the fixed rod 905 locks the movable block 7. When the AC / DC conversion circuit needs to be troubleshooted, the handle 13 is released by rotating the card plate 15, and the pull rod 904 is pulled by pulling the handle 13, and the pull rod 904 drives the movable plate 906 to move, and the movable plate 906 compresses the elastic spring 903, and at the same time, the movable plate 906 drives the fixed rod 905 to move downward, and the fixed rod 905 releases the lock on the movable block 7, and then the sliding protective shell 5 drives the movable block 7 The movable block 7 compresses the elastic spring 8. When the protective shell 5 is moved to a certain position, the locking bolt 17 is rotated to make the locking bolt 17 and the connecting rod 6 surface contact to fix the protective shell 5, and then the AC-DC conversion circuit on the bottom plate 1 is troubleshooted. After the troubleshooting is completed, the locking bolt 17 is rotated in the opposite direction, and the protective shell 5 returns to its original position under the action of the elastic spring 8. The movable block 7 pushes the fixing rod 905 under the action of the inclined surface 10, and the fixing rod 905 locks the movable block 7. Then the handle 13 is located inside the placement slot 11 to complete the troubleshooting of the AC-DC conversion circuit.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
