[0030] 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.

[0031] Reference Figures 1-3This utility model provides an embodiment of an easy-to-maintain electrical automation distribution cabinet, comprising a cabinet body 1. A support frame 2 is fixedly connected to the inner wall of the cabinet body 1, providing support for a mounting frame 4. A sliding groove 3 is provided on the outer wall of the support frame 2, with an inwardly concave T-shape for engaging a slider 5 to maintain its stable vertical movement. A slider 5 is slidably connected to the inner wall of the sliding groove 3, with the slider 5 configured as a T-shaped locking block for engaging the sliding groove 3 to maintain the stable vertical movement of the mounting frame 4. The mounting frame 4 is fixedly connected to the outer wall of the slider 5, and is existing technology used for installing and fixing electrical components. The mounting bracket 4 has a limit component on the back of its outer wall. The cabinet 1 has a door 6 hinged to its outer side. Door 6 is the side wall of the cabinet 1. It is opened by a fixing component to expand the opening angle of the cabinet 1. Door 7 is hinged to the end of the outer wall of door 6. Door 7 is the normal opening door of the cabinet 1 and is used to open the cabinet 1 in a small area. The back of the outer wall of the mounting bracket 4 is slidably connected to the outer wall of the support frame 2. The end of the outer wall of the mounting bracket 4 is slidably connected to the inner wall of door 6. The outer wall of door 6 is slidably connected to the inner wall of the cabinet 1. The outer wall of door 7 is slidably connected to the inner wall of the cabinet 1.

[0032] Reference Figures 2-4 A fixed frame 8 is fixedly connected to the bottom inner side of the outer wall of cabinet door 6. Four sets of fixed frames 8 are provided to maintain the stable up-and-down movement of the fixed block 10 and to provide a fixing point for the return spring 9. Since existing electrical automation distribution cabinets typically use a single-door opening cabinet 1, it is impossible to open the cabinet 1 at a large angle, thus providing operating space for maintenance personnel. The inner wall of the fixed frame 8 is elastically connected to the fixed block 10 via the return spring 9. The fixed block 10 is used to engage with the fixing groove 12 to fix cabinet door 6 to the inner wall of cabinet 1. A fixing rod 11 is fixedly connected to the top of the outer wall of the fixed block 10. The fixing rod 11 is used for external manual movement to release the fixed block 10 from its limit position. A [missing information - likely a design feature] is provided at the bottom of the inner wall of cabinet 1. The fixing groove 12 is used to engage the fixing block 10 to fix the cabinet door 6 and prevent it from being affected by the opening of the cabinet door 7. One end of the return spring 9 is fixedly connected to the inner wall of the fixing frame 8, and the other end of the return spring 9 is fixedly connected to the top of the outer wall of the fixing block 10. Through the opposing pressing force between the return spring 9 and the fixing frame 8, the fixing block 10 is always engaged with the inner wall of the fixing groove 12 without being affected by external force. The outer wall of the fixing block 10 is slidably connected to the inner wall of the fixing frame 8, and the bottom of the outer wall of the fixing block 10 is engaged with the inner wall of the fixing groove 12. The outer wall of the fixing rod 11 passes through and is slidably connected to the inner wall of the fixing frame 8.

[0033] Reference Figures 2-3The limiting component includes a limiting frame 13, which is used to keep the limiting block 15 moving stably and prevent it from shifting due to external forces. The back of the outer wall of the limiting frame 13 is fixedly connected to the back of the outer wall of the mounting bracket 4. The inner wall of the limiting frame 13 is elastically connected to the limiting block 15 through a limiting spring 14. The limiting block 15 is used to engage with the limiting groove 17 to fix the mounting bracket 4. A limiting switch 16 is fixedly connected to the end of the outer wall of the limiting block 15. The limiting switch 16 is used for external manual operation to release the limiting block 15, facilitating manual operation. The outer wall of the support frame 2 has limiting grooves 17, and several sets of limiting grooves 17 are provided. The limit block 15 is used to change the height of the mounting bracket 4. One end of the limit spring 14 is fixedly connected to the middle of the inner wall of the limit frame 13, and the other end of the limit spring 14 is fixedly connected to the bottom of the outer wall of the limit block 15. Through the opposing pressing force between the limit spring 14 and the limit frame 13, the limit block 15 is always locked on the inner wall of the limit groove 17 without being affected by external force. The outer wall of the limit block 15 is slidably connected to the inner wall of the limit frame 13. The outer wall of the limit switch 16 is slidably connected to the inner wall of the limit frame 13. The top of the outer wall of the limit block 15 is locked on the inner wall of the limit groove 17.

[0034] Working principle: When installing electrical components of different sizes, the limit switch 16 is manually pressed in opposite directions to drive the limit block 15 out of the limit groove 17 to release the limit. Then, the mounting bracket 4 is moved up and down to the required position, and the limit switch 16 is released. At the same time, the limit spring 14 pushes the limit block 15 back into the corresponding limit groove 17, so as to quickly adjust the height of the mounting bracket 4 to accommodate electrical components of different heights.

[0035] When electrical components need to be inspected or replaced, open cabinet door 2 7, then manually pull up the fixing rod 11 to drive the fixing block 10 out of the fixing groove 12 to release the limit, then manually open cabinet door 1 6 to drive cabinet door 2 7 to follow, so as to open cabinet body 1 at a large angle, so that maintenance personnel have enough space when operating.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
