[0031] The utility model will be further explained in connection with the drawings and specific embodiments.

[0032] As Figure 1 shown, a low-voltage power distribution cabinet capable of effectively improving the flatness of the bent part of the door panel of the cabinet door, comprising a cabinet body 1, a cabinet door 2 and a top plate 3.

[0033] The cabinet door 2 is arranged at the front end opening of the cabinet body 1; the top plate 3 is arranged at the top of the cabinet body 1.

[0034] As Figure 4 shown, the both side edge positions of the cabinet door 2 are inwardly bent into first square tube-shaped bent zones 4, and a plurality of long through holes 5 are arranged on the outer wall of the first square tube-shaped bent zones 4 in parallel with the door panel of the cabinet door 2 and at equal intervals along the length direction of the door panel of the cabinet door 2; in this way, when the both sides of the cabinet door 2 are bent, the long through holes 5 can increase the deformation amount, so as to avoid the rupture of the bent part of the door panel of the cabinet door.

[0035] As Figure 4 and Figure 5 shown, the both ends of the first square tube-shaped bent zones 4 are outwardly extended to form limiting flat plate zones 6 on the side in parallel with the door panel of the cabinet door 2; the both ends of the door panel of the cabinet door 2 are inwardly bent into second square tube-shaped bent zones 7, and the both ends of the side of the second square tube-shaped bent zones 7 in parallel with the door panel of the cabinet door 2 are outwardly extended to form insertion flat plate zones 8, which are inserted below the limiting flat plate zones 6 and are in close contact with the limiting flat plate zones 6.

[0036] By bending the edge positions on both sides of the door panel of the cabinet door 2 into a first square tubular bending area 4, the upper and lower ends of the door panel of the cabinet door 2 are bent into a second square tubular bending area 7, and both ends of the side of the second square tubular bending area 7 parallel to the door panel of the cabinet door 2 are extended outward to form a plug-in flat plate area 8, and the plug-in flat plate area 8 is plugged under the said limiting flat plate area 6, effectively ensuring the flatness of the bent edge and corner area, so that the door panel of the cabinet door 2 can effectively seal the opening of the cabinet body 1.

[0037] In this embodiment, a horizontal fitting area 9 is extended from the edge positions of the first square tubular bending area 4 and the second square tubular bending area 7, and the horizontal fitting area 9 is fitted with the inner wall of the door panel of the cabinet door 2, further improving the stability and strength of the first square tubular bending area 4 and the second square tubular bending area 7.

[0038] In this embodiment, glue is filled between the limiting flat plate area 6 and the plugging flat plate area 8 to further improve the sealing performance.

[0039] In this embodiment, one end of the top plate 3 is hinged to the top of the cabinet 1, and the other end of the top plate 3 is fixed to the top of the cabinet 1 by bolts, so that the top plate 3 can be opened conveniently for inspection of the upper area inside the cabinet 1.

[0040] Furthermore, in this embodiment, Figure 2 As shown, a number of long holes 10 are evenly provided on the top plate 3, and a bridge-shaped protrusion 11 is provided on the long hole 10. The two ends of the bridge-shaped protrusion 11 are fixedly connected to the two ends of the long hole 10 respectively, which on the one hand plays a role in heat dissipation, and on the other hand effectively prevents external foreign matter from entering the cabinet 1 through the long hole 10.

[0041] Furthermore, a filter screen (not shown in the figure) is provided on the inner wall of the top plate 3 , and the filter screen covers all the long holes 10 , thereby further preventing external foreign matter from entering the cabinet 1 .

[0042] In this embodiment, there is a gap between the bottom plate of the cabinet 1 and the cabinet 1; Figure 3 As shown, a plurality of circular through holes 12 are provided on the bottom plate of the cabinet 1, and a baffle 13 is provided on the circular through hole 12. Two legs 14 are symmetrically provided at the edge of the baffle 13, and the two legs 14 are connected to the circular hole 12. With such an arrangement, when it is necessary to pass a cable through the bottom of the cabinet 1, the two legs 14 of the baffle 13 on the corresponding circular through hole 12 are broken to allow the cable to pass through. The other circular through holes are blocked by the baffle, which effectively prevents external foreign matter from entering the cabinet through the circular through holes and causing damage to the electrical components in the cabinet.

[0043] In this embodiment, if Figure 6As shown, the bottom of the one side outer wall of the cabinet body 1 has a notch 15, which facilitates the copper bar to pass through when other cabinet bodies are used in combination.

[0044] The preferred embodiments of the utility model have been specifically described above, but the utility model is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the application.
