[0027] Reference Figure 1-6An easy-to-install distribution box housing includes a base 1, a top cover box 4, and a connecting box 3. The base 1, top cover box 4, and connecting box 3 are assembled to form the distribution box housing. The connecting box 3 has a "U"-shaped structure. "U"-shaped inserts 12 are fixedly installed on the top of the connecting box 3 and the top of the base 1. "U"-shaped slots 16 are provided on the bottom of the top cover box 4 and the bottom of the connecting box 3. The interior of the top cover box 4 is equipped with a shielding mechanism for covering the distribution box housing. This distribution box housing is composed of a base 1, a connecting box 3, and a top cover box 4, with the connecting box 3 positioned between the base 1 and the top cover box 4. The number of connecting boxes 3 can be increased according to actual usage requirements. The connection between the connecting boxes 3 can be achieved by inserting the insert plate 12 of the bottom connecting box 3 into the slot 16 of the top connecting box 3. The connection between the connecting box 3 and the base 1 can be achieved by inserting the insert plate 12 on the surface of the base 1 into the slot 16 of the connecting box 3. The connection between the connecting box 3 and the top cover box 4 can be achieved by inserting the insert plate 12 on the top of the connecting box 3 into the slot 16 at the bottom of the top cover box 4. This allows for the splicing of the electrical box shell. The appropriate number of connecting boxes 3 can be selected according to actual usage requirements to change the electrical box shell to different volumes, which is convenient for operation and use. The front of the spliced ​​electrical box shell is open, and the set shielding mechanism can shield the opening.

[0028] Furthermore, through holes for bolts are provided on the surface of the connecting box 3 relative to the slot 16, the surface of the insert plate 12, and the side wall of the base 1. By providing through holes, bolts can be used to fasten the insert plate 12 and the slot 16 after they are inserted, thereby further strengthening the robustness of the electrical box shell after assembly.

[0029] Furthermore, the shielding mechanism includes a winding shaft 9, which is rotatably inserted inside the top cover box 4. A shielding cloth 5 is wound around the surface of the winding shaft 9, and a crank handle 10 is fixedly installed at the end of the winding shaft 9. A support roller 11 is rotatably connected inside the top cover box 4. Slide grooves 13 are provided on both sides of the inner wall of the connecting box 3. In use, the shielding mechanism can be used by simply pulling down the shielding cloth 5 to loosen it on the winding shaft 9, thus shielding the outer shell of the electrical box. When it needs to be opened, the crank handle 10 can be manually turned to wind the winding shaft 9 around the shielding cloth 5. Through the support roller 11, the shielding cloth 5 on the winding shaft 9 can be kept inside the slide groove 13 after passing the support roller 11, regardless of how much it is wound or unwound, thus improving ease of use. The rotation between the winding shaft 9 and the top cover box 4 has a certain frictional resistance, so it will not easily rotate without pulling the shielding cloth 5.

[0030] Furthermore, the shielding cloth 5 has a double-layer structure and support rods 8 are evenly fixedly installed inside. A counterweight rod 6 is fixedly installed at the bottom of the shielding cloth 5. A first fixing ring 2 is fixedly installed on the surface of the base 1, and a second fixing ring 7 is fixedly installed on the surface of the counterweight rod 6. The support rods 8 inside the shielding cloth 5 can restrict the support rods 8 by the sliding groove 13 after the shielding plate is unrolled and shielded, so that the shielding cloth 5 and the electrical box shell will not be directly opened due to air flow. The support rods 8 are arranged horizontally, that is, parallel to the winding shaft 9, so that they can be rolled up with the shielding cloth 5 during winding, so that they will not cause any impact in actual use. The counterweight rod 6 can make the entire shielding cloth 5 subject to gravity, making it easier to operate. The first fixing ring 2 and the second fixing ring 7 can be locked with a lock when the shielding cloth 5 is completely shielded, so that the shielding cloth 5 cannot be easily opened.

[0031] Furthermore, partitions 14 are fixedly installed inside the connection box 3 near the inner walls on both sides. The partitions 14 can be used to place partitions on them, which facilitates the fixing of electrical components inside the electrical box.

[0032] Furthermore, the side wall of the connecting box 3 is provided with ventilation holes and a filter screen 15 is fixedly installed inside the ventilation holes. The ventilation holes can dissipate heat from the inside of the electrical box, and the filter screen 15 can filter dust.

[0033] In summary, the electrical box casing consists of a base 1, a connecting box 3, and a top cover box 4. The connecting box 3 is located between the base 1 and the top cover box 4, and the number of connecting boxes 3 can be increased according to actual usage requirements. The connection between connecting boxes 3 can be achieved by inserting the insert plate 12 of the bottom connecting box 3 into the slot 16 of the top connecting box 3. The connection between connecting box 3 and base 1 can be achieved by inserting the insert plate 12 on the surface of base 1 into the slot 16 of connecting box 3. The connection between connecting box 3 and top cover box 4 can be achieved by inserting the insert plate 12 on the top of connecting box 3 into the slot 16 on the bottom of top cover box 4. This allows for the splicing of the electrical box casing, and the appropriate number of three connecting boxes can be selected according to actual usage needs to change the electrical box casing to different volumes, facilitating operation and use. The front of the spliced ​​electrical box casing is open, and the set shielding mechanism can cover the opening. Through holes are set so that the plug plate 12 and the slot 16 can be inserted and then fastened with bolts through the through holes, further strengthening the firmness of the electrical box casing after splicing. In use, the shielding mechanism can be used by simply pulling down the shielding cloth 5 to loosen it on the winding shaft 9, thus covering the electrical box casing. When it needs to be opened, it can be opened by pulling down the shielding cloth 5. When needed, simply turn the crank handle 10 manually to wind the winding shaft 9 around the shielding cloth 5. The support roller 11 ensures that the shielding cloth 5, regardless of how much is wound or unwound, remains within the groove 13 after passing the support roller 11, improving ease of use. A support rod 8 inside the shielding cloth 5 restricts its movement within the groove 13 after unwinding, preventing the shielding cloth 5 from being directly opened by airflow. The support rod 8 is horizontally positioned, parallel to the winding shaft 9, and moves with the shielding cloth during winding. The cloth 5 is rolled up, so it will not affect actual use. The counterweight rod 6 can make the entire covering cloth 5 subject to gravity, making it easier to operate. The first fixing ring 2 and the second fixing ring 7 can be locked with a lock when the covering cloth 5 is completely covered, so that the covering cloth 5 cannot be easily opened. The partition 14 can be used to place a partition on it, which makes it convenient to fix electrical components inside the electrical box. The ventilation hole can dissipate heat from the inside of the electrical box. The filter 15 can filter dust.
