Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 and 2, the bottom plate of the distribution box of the present invention has a double-layer structure, the bottom plate lower layer 1 is a rectangular metal frame 11, and a pair of fixing ear fasteners 12 are oppositely arranged on two sides of the frame; the upper layer 2 of the bottom plate is a grid metal mesh 23 externally provided with a rectangular fixing frame, two sides of the grid metal mesh 23 are oppositely provided with a pair of T-shaped connecting seats 22, and the structures of the T-shaped connecting seats 22 are matched with the fixing ear buckles 12; the side wall of the lower layer 1 of the bottom plate is also provided with a pair of wedge-shaped protrusions 13 to form a combined groove for fixing the rectangular fixing frame of the upper layer 2 of the bottom plate.
The bottom plate lower layer 1 is a rectangular structure formed by two semi-open metal frame bodies in a butt joint mode, and fixing lugs 12 at the connection position of the bottom plate lower layer are fixed together through flanges. A plurality of through holes are uniformly formed in the upper portion of the frame body of the lower layer 1 of the bottom plate, and fixing columns 14 which are the same in number as the through holes and provided with external threads are uniformly arranged on the inner side of the lower portion of the corresponding frame body.
On the basis of the structure, the distribution box bottom plate further comprises a plurality of fixing rods 3, the outer diameters of the fixing rods 3 correspond to the inner diameters of the through holes, counter bores are formed in the bottoms of the fixing rods, and internal threads matched with external threads of the fixing columns are formed in the side walls of the counter bores. Namely, the fixing rod 3 is fixed on the rectangular metal frame body 11 through the through hole limitation and the thread matching of the fixing column.
In order to facilitate the installation and the disassembly, the upper plane of the T-shaped connecting seat 22 is higher than the upper plane of the fixing ear clip.
Besides, the rectangular fixing frame of the upper layer 2 of the bottom plate consists of an upper part and a lower part, and the grid metal mesh 23 is fixed on the lower part rectangular fixing frame 21; preferably, the length of the upper part frame body 4 of the rectangular fixing frame on the upper layer of the bottom plate accounts for 1/5-1/3 of the length of the whole frame body; the upper part and the lower part are connected in an interference fit mode.
