[0017] Reference Figures 1-4 Example 1: A power distribution box with a protective mechanism includes a box body 1. A cabinet door 2 is hinged to one outer wall of the box body 1, and adjacent fixed blocks are welded to one outer wall of the box body 1. A connecting shaft 3 is welded between two fixed blocks, and a retaining strip 4 is rotatably connected to the outer wall of the connecting shaft 3. A spring 5 is fixedly connected between the retaining strip 4 and the fixed block. A positioning plate 6 is welded to one outer wall of the cabinet door 2, and one end of the retaining strip 4 is located inside the positioning plate 6. The spring 5 is located outside the connecting shaft 3.

[0018] The cabinet door 2 of the cabinet body 1 is connected by a hinge, and the fixing block is welded and fixed to the connecting shaft 3. The retaining strip 4 can rotate around the shaft and is reset by the spring 5. When the cabinet door 2 is closed, the retaining strip 4 is embedded in the positioning plate 6, and the spring 5 provides clamping force to ensure that the cabinet door 2 is securely closed.

[0019] In this embodiment, the coordinated design of the locking strip 4, spring 5 and positioning plate 6 enables the cabinet door 2 to lock quickly and reset automatically, enhancing the closing stability and preventing the cabinet door 2 from remaining open if the door is forgotten to be locked, thus improving safety.

[0020] In the second embodiment, reflective stickers 7 are glued to both sides of the outer wall of the box body 1 on one side of the cabinet door 2, and corner protectors 8 are glued to both corners of the bottom outer wall of the box body 1.

[0021] Reflective stickers 7 are affixed to both sides of cabinet door 2 and are made of highly reflective material. Corner pads 8 are made of rubber and are fixed to the bottom corner of cabinet 1 by adhesive. Both improve nighttime visibility and impact resistance, respectively.

[0022] In this embodiment, the reflective sticker 7 can improve visibility at night or in low light conditions, and the corner protector 8 reduces corner damage during handling or installation, further ensuring the integrity of the box 1.

[0023] In embodiment three, the bottom of the inner walls on both sides of the box 1 is provided with a first ventilation groove 9, and a dust cover 10 is welded to one side of the outer walls on both sides of the box 1 located at the first ventilation groove 9.
