Figure 1-3A distribution box guard plate structure, comprising a distribution box 1, a protection assembly 2 is installed in the distribution box 1, the protection assembly 2 comprises a plurality of guard plates 201, two adjacent guard plates 201 are hinged with the same connecting ear 202, both ends of the guard plates 201 in the distribution box 1 are installed with mounting frames 3, the mounting frames 3 comprise two guide plates 301 installed in the distribution box 1, a side upper end of a guide plate 301 is installed with a hanging ear 302 used in conjunction with the guard plate 201, the uppermost guard plate 201 can be hung by the hanging ear 302 to prevent the guard plate 201 from falling, a plurality of guard plates 201 are slidably installed on the inner side of the guide plate 301, a locking assembly 4 is installed on the guide plate 301, the locking assembly 4 comprises a positioning pressure plate 401, two locking members 402 are hinged on the positioning pressure plate 401, the ends of the locking members 402 pass through the guide plate 301 and are coupled and connected with the guide plate 301;

[0022] By adopting the above-mentioned technical solution, the locking piece 402 is turned to adjust the position of the positioning pressure plate 401, so as to realize the locking and loosening of the positioning pressure plate 401 and the guard plate 201. The protective component 2 can be folded or unfolded. After folding and unfolding, the locking piece 402 is turned to lock the position of the guard plate 201. During the folding and unfolding process, the uppermost guard plate 201 is always stuck in the hanging ear 302, which can ensure the complete grounding of the protective component 2. There is no need to shut down the power, and the operation is convenient.

[0023] Reference Figure 1 A box door 5 is hinged on the outside of the distribution box 1, wherein the distribution box 1, the protection component 2, the mounting frame 3, and the box door 5 are all made of metal materials, and the distribution box 1 and the mounting frame 3 provide complete grounding protection for the protection component 2.

[0024] Reference Figure 3 The guard plate 201 includes a baffle 2011 located on the inner side of the mounting frames 3 on both sides, and connecting columns 2012 are fixedly installed at both ends of the baffle 2011. The connecting columns 2012 are slidably installed on the inner sides of the corresponding two guide plates 301, and the uppermost connecting column 2012 is snap-connected with the hanging ear 302. Connecting shafts 2013 are installed on the upper and lower sides of the connecting column 2012 on the baffle 2011. Two hinge holes are provided on the connecting ear 202, and the two hinge holes are slidably connected with the corresponding connecting shafts 2013 respectively. Through the connecting ear 202, multi-section hinges between two adjacent guard plates 201 can be realized, which facilitates the folding of the guard plates 201. The end of the connecting shaft 2013 is threadedly connected with a locking cap 203. Through the detachable design between the locking cap 203 and the connecting shaft 2013, the baffle 2011 and the connecting ear 202 can be separately disassembled and replaced, and an observation port and an operation port can be provided on the baffle 2011 as needed.

[0025] Reference Figure 2A rotating slot is provided on the guide plate 301, and the locking member 402 includes a rotating shaft 4021 slidably installed in the rotating slot. A stopper 4022 adapted to the rotating slot is installed at the lower end of the rotating shaft 4021, so as to adjust the position of the slider 4023 and realize the squeezing and separation of the guard plate 201 by the positioning pressure plate 401. A slider 4023 is rotatably sleeved on the bottom of the rotating shaft 4021, and a guide shaft 4024 is sleeved on the slider 4023.

[0026] Reference Figure 2 A guide groove is provided on the positioning pressure plate 401, and a slider 4023 is slidably installed in the guide groove. A slide groove is provided at the lower end of the guide groove. A guide shaft 4024 is hinged to the guide groove, and a guide shaft 4024 is slidably installed in the slide groove. Through the coordinated use of the guide shaft 4024 and the positioning pressure plate 401, the inclination and parallelism of the positioning pressure plate 401 can be adjusted, the extrusion and separation of the guard plate 201 can be achieved, and the folding and unfolding operations can be completed.

[0027] The implementation principle of the distribution box guard plate structure in an embodiment of the present application is as follows: when the guard plate 201 needs to be locked, the upper and lower locking pieces 402 are both screwed and locked, so that the stop block 4022 is coupled and engaged with the guide plate 301, and the guard plate 201 is squeezed onto the guide plate 301 to form a lock. When folding and unfolding are required, only the lower rotating shaft 4021 needs to be loosened to tilt the positioning pressure plate 401, and the upper end of the positioning pressure plate 401 is used to abut the connecting column 2012 against the hanging ear 302, and the lower end contacts and squeezes the guard plate 201, so that the guard plate 201 can be folded and unfolded as needed. When complete disassembly is required, all the rotating shafts 4021 are loosened at the same time to release the locking of the positioning pressure plate 401 on the guard plate 201, so that the guard plate 201 is separated from the hanging ear 302, and then the guard plate 201 is folded and tilted to be taken out, which is relatively convenient to operate.
