CONCRETE IMPLEMENTATION

[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments.

[0021] With reference to Figures 1-4 A frame type power distribution cabinet structure, including bottom frame 1, top frame 4, the top of bottom frame 1 and the bottom of top frame 4 are respectively fixedly connected with four lower supports 2 and four upper supports 5 at four corners, which jointly constitute the main load-bearing frame of the power distribution cabinet, the connection between bottom frame 1, top frame 4 and multiple lower supports 2 and multiple upper supports 5 is additionally supported by two support plates 15 to enhance the structural strength and stability of the key connection nodes, the upper sides of the left and right sides of bottom frame 1 are each provided with a first fixed plate 3 fixedly connected with the corresponding lower support 2, used for auxiliary installation of cabinet body or internal components, the lower sides of the left and right sides of top frame 4 are each provided with a second fixed plate 16 fixedly connected with the corresponding upper support 5, also used for auxiliary fixing of side plate or bearing part of load.

[0022] A plurality of limiting holes 8 are sequentially formed in each upper support 5, these limiting holes 8 provide multiple fixed position options for the expansion adjustment of upper support 5, and the size and spacing of each limiting hole 8 are the same, ensuring that the height adjustment can be carried out at fixed intervals to realize equidistance adjustment, the top of each lower support 2 is fixedly connected with a fixed sleeve 6 through a bolt, the fixed sleeve 6 serves as a guide and fixed base for upper support 5, the top of each fixed sleeve 6 is provided with a plug-in slot 7 for accommodating and guiding upper support 5, the bottom of each upper support 5 is respectively plugged into the corresponding plug-in slot 7, so that upper support 5 can be expanded and contracted relative to fixed sleeve 6 to adjust the overall frame height, a support frame 9 is fixedly connected to one side of each fixed sleeve 6, and an adjusting mechanism for adjusting the height of upper support 5 is arranged in each support frame 9, through which the relative position of upper support 5 and fixed sleeve 6 can be controlled and locked.

[0023] The adjusting mechanism comprises a moving plate 14 arranged in the support frame 9, the moving plate 14 is movable in a specific direction inside the support frame 9, one side of the moving plate 14 is fixedly connected with a spring 12, the other end of the spring 12 is elastically connected with the inner wall of the support frame 9, the elastic force of the spring 12 continuously acts on the moving plate 14, so that the moving plate 14 has a tendency to move in one direction, a connecting column 11 is sleeved in the spring 12, the connecting column 11 plays a guiding role and prevents the spring 12 from bending when being compressed or stretched, one end of the connecting column 11 is fixedly connected with the moving plate 14, and the other end of the connecting column 11 penetrates outwardly from the support frame 9 and is connected with a pull ring 13, the pull ring 13 is pulled outwardly, so that the elastic force of the spring 12 is overcome and the moving plate 14 is driven to move as a whole, the other side of the moving plate 14 is fixedly connected with a limiting column 10, one end of the limiting column 10 penetrates through one side of the fixed sleeve 6 and is inserted into a corresponding limiting hole 8, when the limiting column 10 is inserted into a certain limiting hole 8 of the upper support frame 5 under the pushing of the spring 12, the axial limiting of the upper support frame 5 is realized, and the upper support frame 5 is prevented from being accidentally stretched or retracted, when it is necessary to adjust the height, the pull ring 13 is pulled to make the limiting column 10 exit from the current limiting hole 8, and the locking is released.

[0024] When the utility model is used, first, the overall height of the frame required is determined according to the installation layout of internal components of the power distribution cabinet or external space requirements. When the operating personnel need to adjust the height, the operating personnel should act on the multiple adjusting mechanisms on both sides of the power distribution cabinet at the same time to ensure that the top frame 4 always remains in a horizontal state.

[0025] Specific operation is that the pull ring 13 is faced, and force is applied outwardly to pull. The movement of the pull ring 13 is transmitted to the moving plate 14 through the connecting column 11, so that the moving plate 14 is forced to compress the spring 12 and displace in the support frame 9. The displacement of the moving plate 14 drives the limiting column 10 fixed thereto to move synchronously, so that the end of the limiting column 10 completely exits from the current limiting hole 8 engaged, and the locking state between the upper support frame 5 and the fixed sleeve 6 is released. At this time, in the state of releasing the locking, the operating personnel can lift upwardly or press downwardly the top frame 4, drive the upper support frame 5 to smoothly slide in the insertion slot 7 of the fixed sleeve 6, and thus change the structural height of the entire cabinet. When it is observed that the upper support frame 5 moves to a target position, that is, another limiting hole 8 on the upper support frame 5 is aligned with the limiting column 10, the pulling force on the pull ring 13 is slowly released. The restoring force of the spring 12 pushes the moving plate 14 and the limiting column 10 to reset until the end of the limiting column 10 is inserted into the target limiting hole 8, the reliable locking of the upper support frame 5 and the fixed sleeve 6 is re-implemented, and the height adjustment is completed. After the adjustment is completed, whether the limiting columns 10 of all the adjusting mechanisms are inserted in place should be checked to ensure the stability of the frame structure. The first fixed plate 3 and the second fixed plate 16 are used for the installation of subsequent side plates or functional modules, and the support plate 15 continuously strengthens the connecting nodes of the main frame, and guarantees the overall rigidity of the structure.

[0026] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
