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.

[0022] Refer to the instruction manual Figure 1-5, a foldable power distribution cabinet according to one embodiment of the present invention includes a folding plate 1, the top of the folding plate 1 is fixedly connected with a connecting rib 2, the outer wall of the connecting rib 2 is fixedly connected with a connecting plate 3, a slot 4 is provided at the bottom of the folding plate 1, and the folding plate 1 as a whole is a separate frame support bracket, a connecting rib 2 and a connecting plate 3 are provided at the top of the folding plate 1, and the connecting rib 2 and the connecting plate 3 are hexagonally arranged at the top of the folding plate 1, wherein a slot 4 with the same depth as the connecting rib 2 and the connecting plate 3 is provided at the bottom of the folding plate 1, and the connecting rib 2 and the connecting plate 3 are plugged into the slot 4 by multiple folding plates 1, so that a complete support member is formed between the multiple folding plates 1;

[0023] The inner wall of the folding plate 1 is fixedly connected with a support member 5. The support member 5 made of low-alloy steel generally has higher strength than ordinary steel. In the distribution cabinet, this means that the interlayer can better withstand external pressure and impact force, and protect the internal electrical components from physical damage. For example, in some environments where vibration or collision may exist, the distribution cabinet with the support member 5 made of low-alloy steel can work more stably, reducing the risk of cabinet deformation and component damage caused by external forces. After proper treatment, the support member 5 often has better corrosion resistance. Compared with ordinary distribution cabinets, the support member 5 can better resist the influence of corrosion factors such as moisture and chemicals. In some harsh working environments, such as humid basements, chemical workshops, etc., this corrosion resistance can extend the service life of the distribution cabinet and reduce maintenance costs. The support member 5 is rotatably arranged on the inner wall of the folding plate 1 in a V shape, and the support member 5 is made of low-alloy steel;

[0024] The inner wall of the folding plate 1 is fitted with a buffer plate 6, and the outer wall of the buffer plate 6 is provided with a pressure rib 7 and a pressure plate 8, and the pressure rib 7 and the pressure plate 8 are fitted between the folding plate 1 and the buffer plate 6, and the outer wall of the buffer plate 6 is fixedly connected with a buffer sheet 9, and one end of the buffer sheet 9 is fixedly connected to the outer wall of the support 5, and the outer wall of the folding plate 1 is clamped with a wrapping cover 10, and the outer wall of the wrapping cover 10 is fixedly connected with a connecting rail 11, and the interior of the connecting rail 11 is clamped with a connecting plate 12, and a buffer plate 6 is provided on the inner wall of the folding plate 1, and a pressure rib 7 and a pressure plate 8 are provided between the folding plate 1 and the buffer plate 6 to press between the folding plate 1 and the buffer plate 6, so that the connection point position of the folding plate 1 transmits the external force received to the buffer plate 6 through the pressure rib 7 and the pressure plate 8, and a buffer sheet 9 is provided between the support 5 and the buffer plate 6, through the buffer sheet 9 The external force on the folding plate 1 is transmitted to the support member 5 to disperse the impact force. Secondly, the folding plate 1, the wrapping cover 10 and the connecting plate 12 are separate frames. In the early stage of assembly, the entire equipment is folded and transported separately through the folding plate 1, the wrapping cover 10 and the connecting plate 12, which is convenient for transportation of the entire equipment frame. The connecting rail 11 and the wrapping cover 10 are mutually clamped, so that the equipment frame can be quickly assembled. In the conventional folding distribution cabinet, the supporting top beam and the supporting beam plate are connected by a hinge and can be quickly assembled. However, due to the influence of the hinge connection, when the supporting beam plate is impacted by an external force, the supporting beam plate is easily deformed, and the connected hinge is easily deformed and separated, causing damage to the supporting beam plate. The frame of this equipment is formed into a hexagonal state by folding the folding plate 1 as a whole, which can be used as the supporting beam or top beam of the cabinet after folding;

[0025] A matching groove 13 is provided inside the connecting rail 11, and a card ball 14 is provided inside the matching groove 13. The outer wall of the card ball 14 is fixedly connected to a card plate 15, and one end of the card plate 15 is fixedly connected to the inner wall of the matching groove 13. A matching groove 2 16 is provided inside the connecting plate 12, and the matching groove 2 16 and the matching groove 13 are arranged on the same horizontal line. A positioning ring 17 is fixedly connected to the inner wall of the matching groove 2 16, and a pressure ring 18 is fixedly connected to the inner wall of the positioning ring 17. A limiting ring 19 is provided inside the matching groove 2 16, and a connecting strip 20 is wound between the limiting ring 19 and the pressure ring 18. A connecting column 21 is provided inside the limiting ring 19, and the connecting column 2 1 is provided with a positioning column 22 on one side, and one end of the positioning column 22 is clamped between the card ball 14 and the card plate 15. A connecting positioning column 23 is provided inside the connecting column 21, and one end of the connecting positioning column 23 extends to the inside of the positioning column 22. The outer wall of the connecting positioning column 23 is wound with a spring 24. The connecting plate 12 is inserted from bottom to top into the interior of the connecting rail 11. When the connecting plate 12 is inserted upward, the positioning ring 17 inside the matching groove 16 presses the connecting strip 20, so that the limiting ring 19 as a whole extends outward inside the positioning ring 17. When the limiting ring 19 extends outward, the limiting ring 19 drives the connecting column 21 inside the limiting ring 19 to move outward;

[0026] The spring 24 on the outer wall of the connecting positioning post 23 presses the positioning post 22, so that one end of the positioning post 22 slides on the inner wall of the connecting rail 11. When sliding to the matching groove 13 inside the connecting rail 11, the connecting positioning post 23 presses the spring 24, so that one end of the positioning post 22 is engaged with the card ball 14 and the card plate 15. When the connecting plate 12 is pushed as a whole again, the positioning post 22 is affected by the pressure of the spring 24, and one end of the positioning post 22 slides along the outer wall of the card ball 14, disengages from the matching groove 13, and continues to slide on the inner wall of the connecting rail 11 until the connecting rail 11 and the connecting plate 12 are flush as a whole, and multiple positioning posts 22 are engaged with the card ball 14 and the card plate 15.

[0027] Working principle: When the equipment is in use, the folding plate 1 as a whole is a separate frame support bracket, and a connecting rib 2 and a connecting plate 3 are set on the top of the folding plate 1. The connecting rib 2 and the connecting plate 3 are hexagonally arranged on the top of the folding plate 1, wherein a slot 4 with the same depth as the connecting rib 2 and the connecting plate 3 is set at the bottom of the folding plate 1. The connecting rib 2 and the connecting plate 3 and the slot 4 are plugged together through multiple folding plates 1, so that a complete support is formed between the multiple folding plates 1. In order to ensure the overall rigidity and impact resistance of the folding plate 1, a support 5 made of low alloy steel is set inside the folding plate 1. The support 5 made of low alloy steel usually has higher strength than ordinary steel. In the distribution cabinet, this means that the interlayer can better withstand external pressure and impact, protecting the internal electrical components from physical damage. For example, in some environments where vibration or collision may exist, the distribution cabinet with the support 5 made of low-alloy steel can work more stably, reducing the risk of cabinet deformation and component damage caused by external forces. After proper treatment, the support 5 often has better corrosion resistance. Compared with ordinary distribution cabinets, the support 5 can better resist the influence of corrosive factors such as moisture and chemicals. In some harsh working environments, such as humid basements and chemical workshops, this corrosion resistance can extend the service life of the distribution cabinet and reduce maintenance costs.

[0028] The thermal expansion coefficient of the support 5 is relatively low, which enables the support and interlayer of the distribution cabinet to maintain good dimensional stability when the temperature changes. This is especially important for some electrical equipment with high precision requirements. Stable dimensions can ensure the installation accuracy and connection reliability of electrical components, and reduce poor contact or failures caused by dimensional changes. Secondly, low-alloy steel has certain electromagnetic shielding properties. In the distribution cabinet, this can effectively reduce the impact of external electromagnetic interference on internal electrical components and improve the reliability and stability of the equipment, especially in some equipment that is sensitive to electromagnetic interference. In occasions such as communication equipment rooms and medical equipment rooms, the power distribution cabinet with low alloy steel interlayer can better protect the internal equipment from electromagnetic interference. A buffer plate 6 is provided on the inner wall of the folding plate 1, and a pressure rib 7 and a pressure plate 8 are provided between the folding plate 1 and the buffer plate 6 to press between the folding plate 1 and the buffer plate 6, so that the connection point of the folding plate 1 transmits the external force received to the buffer plate 6 through the pressure rib 7 and the pressure plate 8. A buffer sheet 9 is provided between the support member 5 and the buffer plate 6, and the external force received by the folding plate 1 is transmitted to the support member 5 through the buffer sheet 9 to disperse the impact force.

[0029] Secondly, the folding plate 1, the wrapping cover 10 and the connecting plate 12 are separate frames. In the early stage of assembly, the entire device is folded and transported separately through the folding plate 1, the wrapping cover 10 and the connecting plate 12, which is convenient for transportation of the entire device frame. The connecting rail 11 and the wrapping cover 10 are mutually clamped, so that the device frame can be quickly assembled. In the usual folding distribution cabinet, the supporting top beam and the supporting beam plate are connected by a hinge and can be quickly assembled. However, due to the influence of the hinge connection, when the supporting beam plate is impacted by external force, the supporting beam plate is easily deformed, and the connected hinge is easily deformed and separated, causing damage to the supporting beam plate. The equipment frame is formed into a hexagonal state as a whole by folding the folding plate 1. After folding, it can be used as a supporting beam or top beam of the cabinet. Secondly, the outer wall of the folding plate 1 is provided with a connecting rail 11. The user engages one end of the connecting plate 12 with the wrapping cover 10 on the outer wall of the folding plate 1, so that the folding plate 1 and the connecting plate 12 form one side of the cabinet as a whole. A matching groove 13 is provided inside the connecting rail 11, and a card ball 14 and a card plate 15 are provided inside the matching groove 13. The card plate 15 is fixed to the outer wall of the matching groove 13, so that a notch that can be engaged with accessories is formed between the matching groove 13 and the card ball 14.

[0030] A matching groove 2 16 is provided inside the connecting plate 12, and the matching groove 2 16 and the matching groove 1 13 are on the same horizontal line. When the folding plate 1 and the connecting plate 12 are assembled, the connecting plate 12 is inserted into the interior of the connecting rail 11 from bottom to top as a whole. When the connecting plate 12 is inserted upward, the positioning ring 17 inside the matching groove 2 16 presses the connecting strip 20, so that the limiting ring 19 as a whole extends outward inside the positioning ring 17. When the limiting ring 19 extends outward, the limiting ring 19 drives the connecting column 21 inside the limiting ring 19 to move outward. A connecting positioning column 23 is provided inside the connecting column 21, and a positioning card column 22 is provided on one side of the connecting positioning column 23. The spring 24 on the outer wall of the connecting positioning column 23 presses the positioning card column 22, so that one end of the positioning card column 22 slides on the inner wall of the connecting rail 11. When it slides into the connecting rail 11 When the matching groove 13 of the part is reached, the positioning column 23 is connected to the spring 24 to make one end of the positioning column 22 engage with the card ball 14 and the card plate 15. When the connecting plate 12 is pushed as a whole again, the positioning column 22 is affected by the pressure of the spring 24, and one end of the positioning column 22 slides along the outer wall of the card ball 14, disengages from the matching groove 13, and continues to slide on the inner wall of the connecting rail 11 until the connecting rail 11 and the connecting plate 12 are flush with each other. At this time, multiple positioning columns 22 are engaged with the card ball 14 and the card plate 15, and the connecting rail 11 and the connecting plate 12 are connected as a whole. By engaging multiple positioning columns 22 with the components inside the matching groove 13, the connecting rail 11 and the connecting plate 12 are assembled and connected as a whole, ensuring that the folding plate 1 and the connecting plate 12 are stable as a whole, which is convenient for the user's subsequent operation.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
