[0021] Example 1: Please refer to Figures 1-2 A high-strength explosion-proof enclosure structure for a switch cabinet includes a cabinet body 1, a door panel 2, a bracket assembly 3, a housing assembly 4, and a heat dissipation assembly 5. The door panel 2 is fixedly installed on one end of the cabinet body 1, the bracket assembly 3 is installed inside the cabinet body 1, the housing assembly 4 is installed outside the bracket assembly 3, and the heat dissipation assembly 5 is installed on the housing assembly 4.
[0022] In the bracket assembly 3, the horizontal member 301 is fixedly mounted on the vertical member 302. A snap-fit protrusion 303 is fixedly mounted on one end of the horizontal member 301, and a second snap-fit protrusion 304 is fixedly mounted on the other end of the horizontal member 301. Protrusions 305 are provided on both ends of the snap-fit protrusion 303.
[0023] In use, the vertical rods 302 in the bracket assembly 3 provide vertical support for the entire structure, and the horizontal rods 301 are fixed on them to form an internal support frame. The snap-fit protrusions 303 and 304 at the ends of the horizontal rods 301 prepare for the subsequent connection and positioning with the housing assembly 4. The protrusions 305 on both sides of the snap-fit protrusions 303 can enhance the stability of the connection and ensure that the bracket assembly 3 can stably support the electrical components and other equipment inside the cabinet 1 during equipment operation.
[0024] Example 2: Based on Example 1, please refer to... Figures 2-3 The outer shell 401 in the housing assembly 4 has a snap-fit groove 402 on its inner side. The snap-fit groove 402 is adapted to the second snap-fit protrusion 304 and is slidably snapped. The outer shell 401 and the transverse rod 301 are fixedly connected by bolts.
[0025] The buffer housing 403 in the housing assembly 4 is fixedly mounted on the inner housing 404. The outer side of the inner housing 404 is provided with a second snap-fit groove 405. The two sides of the end of the buffer housing 403 are provided with snap-fit grooves 407. The snap-fit grooves 407 are adapted to the protrusions 305 and are slidably snapped together.
[0026] In use, based on Embodiment 1, the outer shell 401 is installed onto the bracket assembly 3. The snap-fit groove 402 on the inner side of the outer shell 401 is aligned with the second snap-fit protrusion 304 and slidably snap-fitted. Then, the outer shell 401 is fastened to the transverse rod 301 with bolts, so that the outer shell 401 and the bracket assembly 3 are tightly combined to form an external protective structure. At the same time, the buffer shell 403 is fixed on the inner shell 404, and the second snap-fit groove 405 on the outer side of the inner shell 404 is also ready to be connected to the bracket assembly 3, further improving the construction of the protective system.
[0027] Example 3: Based on Example 2, please refer to... Figures 3-4 The second snap-fit groove 405 in the housing assembly 4 is adapted to the snap-fit protrusion 303 and slides to snap-fit. The inner housing 404 and the transverse rod 301 are fixedly connected by bolts. The buffer housing 403 is uniformly provided with honeycomb buffer plates 406 inside.
[0028] The first heat dissipation strip 501 in the heat dissipation assembly 5 is evenly arranged on the outer shell 401, and the second heat dissipation strip 502 in the heat dissipation assembly 5 is evenly arranged on the inner shell 404.
[0029] In use, based on Embodiment 2, the inner shell 404 is installed on the bracket assembly 3, so that the second snap-fit groove 405 and the snap-fit protrusion 303 are slidably snapped together, and the inner shell 404 is fixed to the transverse rod 301 with bolts. At this time, the honeycomb buffer plate 406 uniformly arranged inside the buffer shell 403 plays a role in explosion protection and shock absorption. When the switch cabinet encounters vibration, collision or possible internal explosion impact, the honeycomb buffer plate 406 can absorb energy and protect the internal electrical components. At the same time, the heat dissipation assembly 5 begins to play its role. The first heat dissipation strip 501 uniformly arranged on the outer shell 401 and the second heat dissipation strip 502 on the inner shell 404 increase the heat dissipation area and dissipate the heat generated by the operation of the switch cabinet in a timely manner, ensuring that the equipment operates stably at a suitable temperature.
