[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a PLC control cabinet that is easy to maintain, including a control cabinet body 1, a rain shelter 2 and a mounting plate 3.

[0023] exist Figure 1 In the control cabinet body 1, a rain shelter 2 is provided at the top, an installation plate 3 is provided inside the control cabinet body 1, a limit mechanism 4 is provided at the end of the control cabinet body 1 near the rain shelter 2, the limit mechanism 4 includes protective doors 401 provided on both sides of the control cabinet body 1, a fixed frame 402 is provided at the end of the control cabinet body 1 near the rain shelter 2, and a motor 403 is installed at the top of the fixed frame 402.

[0024] This easy-to-maintain PLC control cabinet is protected from rain by a rain shelter 2.

[0025] exist Figure 4 In the middle: the output end of the motor 403 is connected to a worm 404 extending into the fixed frame 402 via a coupling. A rotating rod 405 is provided at one end of the fixed frame 402 near the worm 404. A worm wheel 406 is provided on the surface of the rotating rod 405. One end of the worm wheel 406 is meshed with the worm 404.

[0026] This easy-to-maintain PLC control cabinet can drive the worm gear 404 to rotate by starting the motor 403, which in turn drives the worm wheel 406 to rotate.

[0027] exist Figure 4 In the middle: both sides of the rotating rod 405 extend to the outside of the fixed frame 402, and both sides of the rotating rod 405 are connected to the limiting plate 407.

[0028] This easy-to-maintain PLC control cabinet uses a worm gear 406 to rotate a rotating rod 405, which in turn rotates a limiting plate 407.

[0029] See Figures 1-4By starting the motor 403, the output end of the motor 403 can drive the worm gear 404 to rotate. When the worm gear 404 rotates, it can drive the worm wheel 406, which is meshed with it, to rotate. At the same time, when the worm wheel 406 rotates, it can drive the rotating rod 405 to rotate. When the rotating rod 405 rotates, it can drive the limiting plates 407 connected on both sides to rotate. Thus, the limiting plates 407 can be moved away from the surface of the protective door 401, and the protective door 401 can be opened. This makes it more convenient for staff to maintain the internal electronic components and avoids the inconvenience caused by the narrow space.

[0030] See Figures 1-3 and Figure 5 It can be seen that,

[0031] exist Figure 5 In the control cabinet body 1, auxiliary lighting mechanisms 5 are provided at both ends near the mounting plate 3. The auxiliary lighting mechanism 5 includes mounting bases 501 that are symmetrically distributed inside the control cabinet body 1. One end of the mounting base 501 is provided with a rotating wheel 502. One end of the rotating wheel 502 is provided with a rotating rod 503 that extends into the mounting base 501. A threaded rod 504 is provided at the end of the mounting base 501 near the rotating rod 503.

[0032] This easy-to-maintain PLC control cabinet can drive the rotating rod 503 to rotate by rotating the rotating wheel 502.

[0033] exist Figure 5 In the middle: a bevel gear set 505 is connected between the threaded rod 504 and the rotating rod 503, and a displacement block 506 is provided on the surface of the threaded rod 504.

[0034] This easy-to-maintain PLC control cabinet can drive the bevel gear set 505 to rotate by rotating the rotating rod 503, so that the rotation of the bevel gear set 505 can drive the threaded rod 504 to rotate.

[0035] exist Figure 5 In the middle: One end of the displacement block 506 is provided with a connecting rod 507 extending to the outside of the mounting base 501, and the bottom end of the connecting rod 507 is provided with a lighting lamp 508.

[0036] This easy-to-maintain PLC control cabinet can move the displacement block 506, connecting rod 507 and lighting lamp 508 by rotating the threaded rod 504.

[0037] See Figures 1-3 and Figure 5It can be seen that by rotating the wheel 502, the wheel 502 can drive the rotating rod 503 to rotate, which in turn drives the bevel gear set 505 to rotate. Simultaneously, the bevel gear set 505 can drive the threaded rod 504 to rotate, which in turn drives the displacement block 506 to move. The displacement block 506 can then drive the connecting rod 507 to move, and the connecting rod 507 can then drive the lighting lamp 508 to move. This allows the lighting lamp 508 to provide better illumination for the interior of the control cabinet 1 when maintenance is performed, making maintenance of the PLC control cabinet more convenient at night.

[0038] In summary, the output of motor 403 drives worm gear 404 to rotate, which in turn drives worm wheel 406, which is meshed with worm gear 406, to rotate. Simultaneously, worm wheel 406 drives rotating rod 405, which in turn drives limiting plate 407 to rotate. This allows limiting plate 407 to be moved away from the surface of protective door 401, enabling the protective door 401 to be opened. This makes it easier for staff to maintain the internal electronic components, avoiding the inconvenience caused by confined space. Content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
