For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0024] See also Figure 1-Figure 5 The utility model discloses an outdoor photovoltaic energy-saving combiner box, comprising a combiner box body 1, on which a high-performance door panel structure for outdoor use is provided;

[0025] Specifically, the high-performance door panel structure for outdoor use includes a door panel 2 hingedly connected to the opening of the junction box body 1, the inner side surface of the door panel 2 is rotatably connected to the gear 3, the outer side of the door panel 1 is rotatably connected to the shaft 4, the shaft 4 is fixedly connected to the gear 3, and a rotating handle 5 is plugged into the shaft 4, and the plug-in connection makes it more convenient for the rotating handle 5 to rotate; a control rod 6 is rotatably connected to the rotating handle 5, and a screw 7 is fixedly installed on the control rod 6, and a threaded hole 8 is provided on the door panel 1 corresponding to the screw 7, and the screw 7 is threadedly connected to the threaded hole 8, and a protective frame 9 is fixedly installed around the gear 3 on the side of the door panel 1, and a latch 10 is plugged into the protective frame 9 in sequence, and the latch 10 is plugged into the junction box body 1, and a gear row 11, a gear row 2 12 and a gear row 3 13 are fixedly installed on the latch 10 in sequence, and the gear row 11, the gear row 2 12 and the gear row 3 are meshed with the gear 3.

[0026] The staff rotates the control handle 5 to rotate the gear 3, driving the gear row 1 11, the gear row 2 12 and the gear row 3 13 to slide, driving the connected pin 10 to move, and completing the fixation of the door panel 2 to the junction box body 1. The door panel 2 can be easily opened to carry out related work on the junction box body 1. After completion, the door panel 2 is closed, and the control handle 5 is rotated in the opposite direction to insert the pin 10 into the junction box body 1 to fix the door panel 2. The position of the control handle 5 is fixed by rotating the screw 7 and the threaded hole 8 to prevent the shaft 4 from rotating and causing the door panel 2 to loosen.

[0027] Furthermore, a limit plate 16 is fixedly installed on the inner side of the door panel 2 corresponding to the tooth row 1 11, the tooth row 2 12 and the tooth row 3 13, and a slide bar 17 is fixedly installed on the limit plate 16, and the slide bar 17 is plug-connected with the corresponding tooth row 1 11, the tooth row 2 12 and the tooth row 3 13. Through the arrangement of the limit plate 16 and the slide bar 17, the stability of the tooth row 1 11, the tooth row 2 12 and the tooth row 3 13 is higher when moving, and the overall service life is longer.

[0028] Furthermore, a bracket 14 is fixedly mounted on the lower side of the combiner box body 1, and a plurality of support rods 15 are evenly fixedly mounted on the bracket 14, and the support rods 15 are fixedly connected to the combiner box body 1. The bracket 14 can support the combiner box body 1, and when used outdoors, it can reduce the impact of ground water and moisture on the combiner box body 1, and also improve the corresponding stability.

[0029] Further, a rain shield 18 is fixedly installed on the door panel 2 corresponding to the threaded hole 8 and the rotating shaft 4, and the rain shield 18 is arc-shaped. The rain shield 18 can block a certain amount of rainwater and reduce the probability of rust of the rotating shaft 4 and the threaded hole 8.

[0030] Furthermore, a rain shelter 26 is fixedly installed on the upper side of the combiner box body 1. The rain shelter 26 can provide rain protection for the entire combiner box body 1 and the door panel 2, further reducing the probability of being corroded by rain water.

The ventilation holes 19 enable the air inside and outside of the combiner box body 1 to circulate, which helps to dissipate the heat of the electronic components inside the combiner box body 1, and the filter screens 20 prevent mosquitoes from entering the combiner box body 1 and affecting the operation of the internal electrical appliances.

[0032] Further, a knob 21 is fixedly mounted on the upper end of the control rod 6, and a limit ring 22 is fixedly mounted on the control rod 6. The knob 21 can better facilitate workers to rotate the control rod 6, and the limit ring 22 can prevent the control rod 6 from being separated from the control handle 5.

[0033] In addition, the utility model is provided with an observation window 23 and a handle 24 on the outer side of the door panel 2, and a rotation mark line 25 is provided on the door panel 2 corresponding to the rotation handle 5. The observation window 23 can facilitate workers to directly view the inside of the combiner box body 1, and the handle 24 is convenient for workers to control the door panel 2. The worker can clearly know the direction of opening and closing of the door panel 2 corresponding to the rotation direction through the rotation mark line 25.

[0034] When in use, the staff first loosens the connection between the threaded hole 8 and the screw 7, and rotates the control handle 5 to rotate the gear 3, driving the gear row 1 11, the gear row 2 12 and the gear row 3 13 to slide, driving the connected pin 10 to move, and completing the fixation of the junction box body 1. The door panel 2 can be easily opened through the handle 24 to carry out related work on the junction box body 1. After completion, it is necessary to close the door panel 2, rotate the control handle 5 in the opposite direction, so that the pin 10 is inserted into the junction box body 1, and the door panel 2 is fixed. Then, the position of the control handle 5 is fixed by rotating the screw 7 and the threaded hole 8 to prevent the rotating shaft 4 from rotating and causing the door panel 2 to loosen.

[0035] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
