5. A method for using a high and low voltage distribution cabinet with a protective function, characterized in that: The specific steps include: S1. Before use, when installing the power distribution cabinet body (101), first insert the two conical cylinders (111) into the ground and fix them, and then go to step S2; S2. When the protective door panel (201) needs to be opened during use, first hold the anti-static wristband (220) with your hand and pull the second cable (217). While holding the anti-static wristband (220), use the connection of the second cable (217), the blocking plate (213), the latch guide rod (212) and the plug (113) to guide the static electricity of the body into the ground through the conical tube (111), thereby eliminating the static electricity on the surface of the body and improving the protection. Then continue to pull the second cable (217). When the second cable (217) continues to be pulled up, it will pull the latch guide rod (212) and the lifting plate (214) at the same time under the guidance of the curved guide tube (216). The sliding plate (211) is lifted up by the limit of the slider sleeve (223), and the curved pressure plate (221) is lifted up. After the sliding plate (211) is lifted up, it will separate from the curved plate (210). At this time, the curved pressure plate (221) loses the hooking limit of the curved plate (210). After the lifting is completed, the electrostatic wristband (220) is hung on the bottom of the hook plate (209) for fixing. Then, the handle frame (208) is held by hand and the two protective door panels (201) are pulled to flip open to both sides. When the protective door panels (201) are flipped, the first cable (109) is pulled. After the first cable (109) is pulled, it is guided by the first guide wheel (117), the second guide wheel (118), the inner groove ball (108) and the guide ring (107), and the counterweight seat (105) is pulled up in the limit of the vertical guide rod (104). At the same time, the rise of the counterweight seat (105) compresses the first spring (106) to store force. When the protective door panel (201) is flipped to ninety degrees, the positioning frame (203) is docked with the L-shaped pressure plate (114), and then Then, the user stands on the top of the pedal (116) with his feet and presses the pedal (116) downward. When the pedal (116) descends, the plug (113) and the L-shaped pressure plate (114) are driven to descend. When the L-shaped pressure plate (114) descends, it is inserted into the inner side of the positioning frame (203) to fix the protective door plate (201). When the protective door plate (201) is flipped open, the arc pressure block (225) is no longer squeezed by the inner wall of the distribution cabinet body (101). At this time, the fifth spring (224) uses elastic force to drive the arc pressure plate (221) to move to both sides and separate from the curved plate (210). Then, the equipment inside the distribution cabinet body (101) is operated. S3. When the work is completed or the user needs to temporarily leave the distribution cabinet body (101), if the user leaves from the top of the pedal (116), the second spring (115) pushes the pedal (116) and the L-shaped pressure plate (114) to rise, and the L-shaped pressure plate (114) no longer limits the positioning frame (203) after rising. At this time, the first spring (106) pushes the counterweight seat (105) to descend along the vertical guide rod (104). At this time, due to the interference fit between the counterweight seat (105) and the vertical guide rod (104), there is friction, so the counterweight seat (105) can only be moved by the first spring (106). The spring (106) pushes the counterweight seat (105) to slowly descend. At this time, after the counterweight seat (105) descends, the first cable (109) is used to pull the protective door plate (201) under the guidance of the guide ring (107), the inner groove ball (108) and the first guide wheel (117) to slowly turn over and reclose with the power distribution cabinet body (101). When the protective door plate (201) turns over and resets, the arc pressure block (225) is squeezed by the side wall of the inner cavity of the power distribution cabinet body (101). At this time, the arc pressure plates (221) on both sides will move toward each other under the thrust of the arc pressure block (225). The arc pressure plates (221) 1) will squeeze the curved plate (210) to drive the handle frame (208) and the hook plate (209) to move backward under the guidance of the transverse rod (204). Since the hook plate (209) is retracted into the retraction opening (202), the electrostatic wristband (220) is squeezed and separated from the surface of the hook plate (209). Then, the electrostatic wristband (220) rises under the elastic force of the fourth spring (218) and re-connects with the curved guide tube (216). At the same time, the pin guide rod (212) and the lifting plate (214) also fall under the elastic force of the fourth spring (218). The pin guide rod (212) and the lifting plate (214) are also lowered under the elastic force of the fourth spring (218). 2) Reinsert the positioning slot (207) and the insert plug (113), and the lifting arc block (215) is lowered to contact the arc pressure plate (221) and then flipped over without hard contact with the arc pressure plate (221), and then the lifting arc block (215) is relocated to the bottom of the arc pressure plate (221). At the same time, the arc end of the arc pressure plate (221) squeezes the curved plate (210) and separates from the curved plate (210) and completes the clamping. At this time, the handle frame (208) is re-extended from the retraction opening (202) under the elastic force of the third spring (206) to facilitate the next use.
