[0036] The mounting assembly 7 includes a sleeve 71 arranged at the bottom end of the box cover 2. The bottom end of the sleeve 71 is connected to a connecting block 73 through a second spring 72. A pressure block 74 is provided at the upper end of the connecting block 73. A slider 76 is provided on the outer wall of the pressure block 74. A rotating rod 75 is provided on the upper end of the pressure block 74. A first straight groove 77 is provided on the inner wall of the sleeve 71. An annular groove 78 is provided at the lower end of the sleeve 71 located at the first straight groove 77. A second straight groove 79 is provided at one end of the sleeve 71 located at the annular groove 78.

[0037] The connecting block 73 is movably inserted into the inner wall of the sleeve 71, the upper end of the connecting block 73 overlaps the lower end of the pressing block 74, the pressing block 74 is movably inserted into the inner wall of the sleeve 71, and the outer wall of the rotating rod 75 is rotatably connected to the upper end of the electrical box 1.

[0038] The inner wall of the sleeve 71 is vertically provided with a first straight groove 77 from top to bottom, and the outer wall of the slider 76 can slide up and down along the first straight groove 77. The sleeve 71 is located at the lower end of the first straight groove 77 and an annular groove 78 is formed in an annular manner. The first straight groove 77 and the annular groove 78 are connected, and the slider 76 can slide along the inner wall of the annular groove 78. The sleeve 71 is located at the upper side of the end of the annular groove 78 and a second straight groove 79 is formed. The lower end of the second straight groove 79 is connected to the annular groove 78, and the slider 76 can slide up and down along the inner wall of the second straight groove 79

[0039] The four corners of the lower end of the box cover 2 are fixed with reinforcing ribs 8, and the reinforcing ribs 8 are in contact with the four corners of the inner wall of the electrical box 1.

[0040] When the electrical appliance to be placed is placed in the electrical appliance box, the reinforcing ribs 8 at the four corners of the lower end of the box cover 2 are aligned with the four corners of the electrical appliance box 1, and the box cover 2 is set to the upper end of the electrical appliance box 1.

[0042] Reference Figure 1-7 , which is the second embodiment of the present utility model, and this embodiment differs from the first embodiment in that: the moisture absorbing component 3 includes a heat dissipation plate 31 fixedly inserted in the middle end of the box cover 2, and a plurality of heat dissipation holes 32 are evenly opened at the upper and lower ends of the heat dissipation plate 31;

[0043] The moisture absorption component 3 also includes a fixed plate 33 arranged at the lower end of the heat dissipation plate 31. The outer wall of the four ends of the fixed plate 33 is evenly opened with a plurality of through holes 34. The lower end of the through hole 34 is movably inserted with a baffle 35, and the baffle 35 is in contact with the inner wall of the through hole 34. A limiting rod 36 is movably inserted into the outer wall of one side of the fixed plate 33. The outer wall of the limiting rod 36 is movably sleeved with a first spring 37. The two ends of the first spring 37 are respectively fixedly connected to the fixed plate 33 and the limiting rod 36. One end of the limiting rod 36 passes through the outer wall of the fixed plate 33 and overlaps the lower end of the baffle 35. The upper end of the baffle 35 is provided with a plurality of drying balls 38.

[0044] Most electrical boxes and box covers are sealed by bolts, which results in poor heat dissipation performance during the operation of the internal electrical appliances. The device is provided with a heat sink 31, which can be made of heat-absorbing material. Through the heat sink 31, the heat inside the electrical box 1 is gathered to the inside of the heat sink 31 through the through holes 34, and the heat is accelerated through the heat dissipation holes 32 to circulate with the outside air to accelerate the heat dissipation. Since the heat dissipation holes 32 are connected to the outside air, the humid air from the outside enters the fixed plate 33 through the heat dissipation holes 32. The drying ball 38 in the fixed plate 33 can dry the humid air from the outside to prevent the humid air from entering the electrical box 1 and causing the internal electrical short circuit. When the drying ball 38 needs to be replaced, the limit rod 36 can be pulled outward, and the limit rod 36 stretches the first spring 37. After the limit rod 36 leaves the baffle 35, the baffle 35 is removed from the lower end of the fixed plate 33, and the drying ball 38 inside the fixed plate 33 is replaced.
