[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 7 The utility model provides a technical solution: a photovoltaic grid-connected distribution box, comprising a box body 1, an upper box door 2 and a lower box door 3 respectively arranged on the front of the box body 1, an electric meter 14 installed inside the box body 1, and a wire entry hole 4 arranged on one side of the box body 1, a glass window 8 is provided on the upper box door 2, and an LED light strip 13 is installed on the inner side of the upper box door 2. The LED light strip 13 is used for lighting, so that the staff can read the electric meter 14 at night. Since the position of the glass window 8 generally corresponds to the position of the electric meter 14, the LED light strip 13 is distributed around the glass window 8, so as to achieve a good lighting effect and fully illuminate the electric meter 14. A bracket 5 is also fixedly connected to the inner side of the upper box door 2, and a touch switch 6 is provided on the bracket 5. The touch switch 6 is used to control the opening or closing of the LED light strip 13, and an operating mechanism 9 for pressing the touch switch 6 is provided on the upper box door 2;

[0024] The operating mechanism 9 includes a sleeve 91 that is arranged on the upper box door 2. A sliding sleeve 92 is movably installed inside the sleeve 91. When the LED light strip 13 needs to be temporarily turned on, the sliding sleeve 92 is pushed inward, and the sliding sleeve 92 drives the push rod 96 to move. The push rod 96 presses the touch switch 6 to turn on the LED light strip 13 for lighting. At this time, if the sliding sleeve 92 is released, the sliding sleeve 92 will reset under the action of the spring 97, and the push rod 96 will no longer press the touch switch 6, and the LED light strip 13 will be turned off immediately. If the LED light strip 13 needs to be turned on for a long time, after pushing the sliding sleeve 92, the sliding sleeve 92 is rotated in the direction indicated by the twist mark 11. The sliding sleeve 92 drives the protruding rod 94 to rotate, and the protruding rod 94 is stuck in the short side of the L-shaped groove 95. At this time, the sliding sleeve 92 cannot be reset, and the push rod 96 continues to be connected. When the touch switch 6 is touched, the LED light strip 13 is continuously turned on. A horizontal block 93 is provided at one end of the sliding sleeve 92. The horizontal block 93 facilitates the staff to rotate the sliding sleeve 92. The other end of the sliding sleeve 92 is provided with a push rod 96 that is slidably connected to the sleeve 91. The outer sleeve of the push rod 96 is provided with a spring 97. The spring 97 is used to apply thrust to the sliding sleeve 92 so that the sliding sleeve 92 can automatically reset. A convex rod 94 is provided on the outer side of the sliding sleeve 92, and an L-shaped groove 95 is provided on the sleeve 91. The convex rod 94 can slide in the L-shaped groove 95. A sealing ring 98 is provided between the sleeve 91 and the sliding sleeve 92. The sealing ring 98 is used to seal the sliding sleeve 92 and the sleeve 91 to prevent external moisture from entering the box body 1 along the gap between the sliding sleeve 92 and the sleeve 91, affecting the normal operation of the electrical equipment in the box body 1.

[0025] The touch switch 6 is electrically connected to the LED light strip 13 , so that the touch switch 6 can control the LED light strip 13 .

[0026] Among them, a light mark 12 and a twist mark 11 are respectively provided on the outside of the box body 1. The light mark 12 is used to remind people that the lighting can be turned on here, and the twist mark 11 is used to remind people to lock the direction of rotation.

[0027] Among them, an anti-electric shock sign 10 is provided on the outer side of the lower box door 3. The anti-electric shock sign 10 indicates the dangerous voltage and current areas that may exist around, reminding people to stay away from these dangerous areas, thereby effectively avoiding the occurrence of electric shock accidents.

[0028] Among them, a sealing strip 7 is provided between the glass window 8 and the upper door 2. The sealing strip 7 is used to improve the seal between the glass window 8 and the upper door 2 to prevent rainwater from entering the box body 1 through the gap between the glass window 8 and the upper door 2.

[0029] Specifically, when the LED light strip 13 needs to be temporarily turned on for reading at night, the sliding sleeve 92 is pushed inward, the sliding sleeve 92 will compress the spring 97, the sliding sleeve 92 drives the push rod 96 to move, the push rod 96 presses the touch switch 6, and the touch switch 6 turns on the LED light strip 13 for lighting. At this time, if the sliding sleeve 92 is released, the sliding sleeve 92 will be reset under the action of the spring 97, the push rod 96 will no longer press the touch switch 6, and the LED light strip 13 will be turned off immediately, achieving the effect of temporarily turning on the LED light strip 13. If the LED light strip 13 needs to be turned on for a long time, after pushing the sleeve 92, when the protruding rod 94 moves to the end of the long side of the L-shaped groove 95 and is blocked by the sleeve 91 and cannot move, the sleeve 92 is rotated by the cross block 93 in the direction indicated by the torsion mark 11. The sleeve 92 drives the protruding rod 94 to rotate, and the protruding rod 94 is stuck in the short side of the L-shaped groove 95. Even if the sleeve 92 is released, the sleeve 92 cannot be reset, the push rod 96 continues to contact the touch switch 6, and the LED light strip 13 continues to be turned on.
