[0019] like Figure 1-5As shown, the power distribution box involved in the utility model comprises a distribution box bottom plate 1, a distribution box beam 2 and a distribution box cabinet door 3, wherein the distribution box beam 2 comprises an outer portion 12 mounted on the beam, and the front end of the outer portion 12 mounted on the beam is vertically bent inward to form an outer portion 11 mounted in front of the beam, an outer portion 10 mounted under the beam, and a bottom portion 11 mounted on the beam. The lower beam receiving outer portion 10 is bent inwardly 180 degrees to form a lower beam receiving inner portion 9 that fits with the lower beam receiving outer portion 10. The lower beam receiving inner portion 9 is vertically bent to sequentially form a front beam mounting inner portion 8 that fits with the front beam mounting outer portion 11, a beam middle joint 7, a beam inner stopper 6, and a beam mounting inner portion 5 that fits with the bottom of the upper beam mounting outer portion 12. The rear end of the upper beam mounting outer portion 12 is bent inwardly 180 degrees to wrap the upper beam mounting inner portion 5. A beam main through hole is formed between the upper beam mounting outer portion 12, the front beam mounting outer portion 11, the beam inner stopper 6 and the beam middle joint 7. The front beam mounting inner portion 8 is provided with a front and rear A wire inlet and outlet 15 is penetrated and spaced apart, the lower beam receiving inner part 9 is provided with internal threaded winding posts 16 spaced apart between the middle beam joint 7 and the lower beam receiving inner part 9, and external threaded winding posts 17 spaced apart, the upper part of the front beam mounting outer part 11 is at the main beam through hole, and the front part of the upper beam mounting outer part 12 is at the main beam through hole.
