Specific embodiment

The utility model is further elaborated in the following with reference to the drawings and specific embodiments.

As shown in Figures 1 to 6, a kind of photovoltaic header box, including front housing 1, main body 2, rear shell 3, partition 4, fixing groove 5, Sliding rail 6, lockset 7, lock 8, penetration pipe 9, the front housing 1 and rear shell 3 are respectively hinged at the left and right ends position on 2 right side of main body, Partition 4 is welded on inside main body 2, and the inner space of main body 2 is divided into equal two parts, and be arranged on partition 4 etc. Equidistant fixing groove 5, fixing groove 5 are the through slot through partition 4, and the sliding rail 6 is bolted in fixing groove 5, lockset 7 Be fixed on the left side middle position of main body 2 by nut, the lock 8 altogether there are two, be respectively welded at front housing 1 and rear shell 3 Inner left wall middle position, the movable plate for driving lockset 7 can be caught in lock 8, and the penetration pipe 9 is equidistantly fixed on main body 2 bottom, and penetration pipe 9 is equally fixed in the same axial location of the partition other end.

The two sides of the partition 4 can install the sliding rail 6 of fixed different length size according to actual needs, to install not Same electrical equipment.

The sliding rail 6 is the T-shaped piece of engineering plastics production, and 6 top of sliding rail is equipped with through the logical of 6 upper and lower ends of sliding rail Slot, through slot can be fabricated to different length size for installing bolt use, sliding rail 6 according to actual needs.
