Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a control cabinet that is easy to maintain. Background Technology

[0002] The control cabinet is the core hub of a modern industrial automation system, a complete set of equipment integrating various electrical components. Its main function is to centrally control, protect, monitor, and regulate motors, machinery, or industrial production processes.

[0003] A standard control cabinet typically contains key components such as circuit breakers, contactors, relays, frequency converters, PLCs (programmable logic controllers), switching power supplies, and terminal blocks. They work together to achieve automatic or manual switching of circuits, motor start-up and speed regulation, precise control of process parameters (such as temperature and pressure), and fault protection against overload and short circuits.

[0004] Control cabinets are widely used in almost all industrial fields, including machinery manufacturing, metallurgy, chemical industry, power, water supply, and building automation. Their advantages include improved production efficiency, ensuring safe and stable equipment operation, saving labor costs, and providing a solid foundation for intelligent and remote monitoring. Conventional control cabinets are tall and narrow, housing various electrical components. During routine maintenance, the control cabinet only has a front door, resulting in a small operating surface, and components near the corners are difficult to fully expose, indicating room for technological improvement.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, in conjunction with Appendix Figure 1 , 2 A control cabinet that is easy to maintain includes a cabinet body 1, an electrical box 2 on the cabinet body 1; the cabinet body 1 includes a base plate 3, a back plate 4, a left side plate 5, a right side plate 6, and a cabinet door 7.

[0025] The lower end of the back plate 3 is fixedly connected to the rear side of the base plate 3, and the upper end is fixedly connected to the rear side of the bottom surface of the electrical box 2; the back plate 4 serves to connect and support the base plate 3 and the electrical box 2, ensuring overall stability.

[0026] In addition, several heat dissipation slots 9 are arranged from top to bottom on the left side plate 5 and the right side plate 6, through which internal and external air exchange is carried out;

[0027] Combined with appendix Figure 1 , 2 3. Cabinet door 7 is hinged to right side panel 6. Cabinet door 7 is provided with a handle 8 for rotation. A door lock assembly is provided between the back of cabinet door 7 and left side panel 5, which is a conventional structure in the prior art. The rear ends of left side panel 5 and right side panel 6 are both hinged to back panel 4, thereby realizing the rotation opening and closing of left side panel 5 and right side panel 6.

[0028] Based on the above structure, baffles 14 are fixedly connected to both sides of the bottom of the electrical box 2. The baffles 14 contact the upper ends of the left side plate 5 and the right side plate 6 respectively. The baffles 14 are rotatably provided with limiting strips 15 that can limit the left side plate 5 and the right side plate 6. The baffles 14 can provide support for the left side plate 5 and the right side plate 6, and avoid deformation of the upper ends of the left side plate 5 and the right side plate 6 due to repeated opening and closing.

[0029] Based on the above structure, a connecting structure is provided between the bottom of the left side panel 5 and the right side panel 6 and the bottom plate 3. Specifically, the connecting structure includes limiting inserts 10 provided on the bottom of the opposite sides of the left side panel 5 and the right side panel 6, and limiting slots 11 on both sides of the bottom plate 3 that can accommodate the limiting inserts 10. By inserting the limiting inserts 10 into the limiting slots 11, the connection strength between the left side panel 5, the right side panel 6 and the bottom plate 3 is improved, and deformation is avoided. In the above structure, a magnetic block 12 is provided at the opposite end of the limiting inserts 10, and a magnetic block 2 13 that attracts the magnetic block 12 is provided in the limiting slots 11. By attracting the magnetic blocks 12 and 13, the left side panel 5 and the right side panel 6 are not easy to detach during daily use, providing a certain degree of limitation. Combined with the door lock assembly, the overall structure of the cabinet is stable.

[0030] Example 2, in conjunction with Appendix Figure 2 , 4The system also includes a cable tie 16, on which several cable tie rings 17 are adjustable. Each cable tie ring 17 includes a semi-circular fixing plate 18. One end of the fixing plate 18 is fixed with an elastic band 19, and the other end of the elastic band 19 is provided with a magnetic block 20. The other end of the fixing plate 18 is provided with a magnetic block 21 that attracts the magnetic block 20. When limiting the cable, the cable is placed in the corresponding semi-circular fixing plate 18, and the elastic band 19 is magnetically attracted to the other end of the fixing plate 18 to achieve the limiting.

[0031] Based on the above structure, the outer side of the fixing plate 18 is provided with a movable ring 22 that can slide on the cable tie 16; the cable tie 16 is provided with a plurality of threaded holes, and the movable ring 22 is provided with a second threaded hole corresponding to one of the threaded holes, and the second threaded hole and the threaded hole are connected by bolts; the above structure can fix the movable ring 22 and the corresponding cable tie ring 17 in the corresponding position, so that the cable tie ring 17 can be moved to the corresponding position according to the location of the cable concentration, which is highly flexible.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
