[0041] The dust baffle is controlled by the driving assembly through the limiting rod to block or open the mounting hole.

[0042] As can be seen from the above description, the beneficial effects of the present utility model are as follows: By providing a plurality of limiting rods and a plurality of limiting springs at the upper end of the driving plate, and cooperating with the limiting grooves at the bottom ends of the plurality of dust baffles, the up-and-down driving of the dust baffles can be realized, enabling the operator to quickly open the plurality of wiring holes on the electrical box of the electrical equipment, facilitating the access of wires and limiting their positions. The wiring holes without connected wires can also be closed by the dust baffles, effectively blocking the path of external dust or impurities from entering the interior of the electrical box, greatly improving the operating stability and service life of the electrical equipment, and making the practicality of the electrical box of the electrical equipment better.

[0043] Further, the driving assembly includes a driving plate and a threaded rod, and the limiting rod is connected to the top end of the driving plate;

[0044] The threaded rod passes through the through hole at the bottom of the junction box from the outside and is rotatably connected to the bottom of the driving plate.

[0045] As can be seen from the above description, by rotating the threaded rod, the driving plate can be driven to move up and down. The movement of the driving plate will drive the plurality of limiting rods to move, and the limiting rods will drive the plurality of dust baffles to move through the limiting springs, thereby realizing the operation of opening or closing the wiring holes and preventing external dust or impurities from entering the main body of the electrical box, improving the practicality of the electrical box.

[0046] Further, a plurality of clamping plates are provided on both sides of the dust baffle, and clamping grooves corresponding to the clamping plates are provided in the accommodating space.

[0047] As can be seen from the above description, through the cooperation of the plurality of clamping plates on both sides of the dust baffle and the plurality of clamping grooves on both sides of the rectangular groove, the moving positions of the plurality of dust baffles can be restricted, preventing their positions from shifting during movement.

[0055] Further, a fixing plate is provided at the bottom end of the locking rod, and a positioning spring is sleeved outside the locking rod;

[0056] The fixing plate is connected to the fixing ring through the positioning spring.

[0057] As described above, by connecting the fixing plate and the fixing ring through the positioning spring, it is prevented that the fixing plate and the locking rod fall off from the fixing ring, and when the positioning spring contracts, the position of the locking rod can be limited, so that the locking rod always passes through the fixing ring. When the fixing ring coincides with the locking ring, the fixing rod can always pass through the fixing ring and the locking ring, thereby limiting the position of the mounting cover.

[0058] Further, positioning plates are provided on both sides of the bottom of the mounting cover, and positioning grooves corresponding to the positioning plates are provided on both sides of the top of the box body;

[0059] The positioning plate is slidably connected to the positioning groove.

[0060] As described above, through the positioning plates on both sides of the bottom end of the mounting cover, cooperating with the positioning grooves on both sides of the upper end of the box body, the installation position of the mounting cover can be restricted, facilitating the assembly between the mounting cover and the box body; at the same time, the sealing performance of the electrical box body can be ensured, avoiding adverse effects of the external environment on the internal electrical equipment.

[0061] Further, a handle is provided on the top of the mounting cover.

[0062] As described above, through the handle, the movement of the mounting cover can be facilitated, facilitating the opening or closing of the electrical box body.

[0063] Further, openings are provided on both sides of the electrical box body, and filter nets are provided at the openings.

[0064] As described above, openings are provided on both sides of the electrical box body to facilitate the heat dissipation of the electrical equipment. At the same time, filter nets are installed at the openings to avoid dust or impurities in the external environment from entering the inside of the electrical box body and having an adverse effect on the electrical equipment.

[0065] A dust-proof electrical box according to this embodiment is used for centrally placing, connecting, and protecting electrical components, and is applicable to various devices and systems, such as electronic instruments, communication systems, automatic control systems, machine tools, generators, etc. It can not only protect electrical equipment from the influence of the external environment on internal electrical components, such as moisture, dust, corrosion, etc., but also ensure the safe operation of the circuit through insulating materials and isolation devices, prevent current short-circuits and electric leakage, thereby protecting the safety of personnel and equipment.
