Description

Technical Field

[0001] This utility model relates to the technical field of power cabinet frames, specifically a structurally stable power cabinet frame. Background Technology

[0002] Electrical cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), metering cabinets (boxes), etc. They are the final-level equipment in the power distribution system, and contain a variety of devices such as switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment. With the increasing integration of electrical cabinets, higher requirements are placed on the strength of the electrical cabinet frame (skeleton) and modular assembly.

[0003] Chinese Patent Publication No. CN217507933U discloses a reinforced power cabinet frame and power cabinet, comprising: two opposing side frames and a set of side beams connected between the side frames. Each side frame includes two opposing main columns and main beams connected to both ends of the main columns. The main columns are made of a first C-shaped profile, and the main beams are made of a second C-shaped profile. The first C-shaped profile includes a first outer surface and two inner surfaces formed by bending the two sides of the first outer surface inward twice. The second C-shaped profile includes a second outer surface and two third outer surfaces formed by bending the two sides of the second outer surface outward twice. The two ends of the second outer surface are bent once to form a first insertion part. The first insertion part is inserted into the inner side of the first outer surface of the first C-shaped profile and fixed by bolts. The two ends of the third outer surface abut against the inner surface of the first C-shaped profile.

[0004] In the above scheme, after the main crossbeam is fixed to the main column by the plug-in part at the end of the main crossbeam through the screw connection, its third outer side and the second outer side of the main column can support each other, so that the structure is more stable and reliable. However, it has the following disadvantages: In this power cabinet frame, the internal and external walls of the C-shaped material are not provided with support structures, which makes the middle of the C-shaped material prone to bending or deformation when under stress, thereby reducing the overall load-bearing capacity and stability of the power cabinet frame. Utility Model Content

[0005] The purpose of this utility model is to provide a structurally stable power cabinet frame to solve the problem that the C-shaped profile in the power cabinet frame does not have a supporting structure on its internal and external walls, which makes the middle part of the C-shaped profile prone to bending or deformation when under stress, thereby reducing the overall load-bearing capacity and stability of the power cabinet frame.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a structurally stable power cabinet frame, including a fixed base, the fixed base being fixed to the bottom surface of several C-shaped profiles, two first connecting brackets being threadedly connected between two adjacent C-shaped profiles, two second connecting brackets being threadedly connected to the two first connecting brackets, an mounting bracket being threadedly connected between the two second connecting brackets, and a support assembly, the support assembly being disposed above the fixed base for supporting the C-shaped profiles.

[0007] Preferably, the support assembly includes two X-shaped frames, which are respectively fixed between several C-shaped profiles. The bottom surface of the X-shaped frame is fixed to the top surface of the fixed base. Several reinforcing ribs are fixed to the top surface of the fixed base, and the reinforcing ribs correspond to the C-shaped profiles. Limiting strips are fixed to the inner wall of the C-shaped profiles. A connecting plate is snapped onto the inner wall of the C-shaped profiles. Several limiting holes are opened on the top surface of the connecting plate. The reinforcing ribs are slidably connected to the limiting holes. The connecting plate is threadedly connected to the inner wall of the C-shaped profiles. Several supporting blocks are threadedly connected to the top surface of the fixed base, and the supporting blocks are threadedly connected to the C-shaped profiles.

[0008] Preferably, the top surface of the fixed base has two mounting slots, and a counterweight is placed on the inner wall of the mounting slot.

[0009] Preferably, the top and bottom surfaces of the mounting bracket are provided with sliding grooves, the inner wall of the sliding grooves is provided with a plurality of positioning grooves, the inner wall of the sliding grooves is slidably connected to the mounting block, the top surface of the mounting block is provided with positioning holes, the positioning holes correspond to the positioning grooves, the inner wall of the positioning holes is slidably inserted with positioning posts, the positioning posts extend into the positioning grooves, the outer wall of the positioning posts is wound with springs, the bottom end of the springs is fixed to the inner wall of the positioning holes, and the top end of the springs is fixed to the outer wall of the positioning posts.

[0010] Preferably, a shock-absorbing pad is fixed to one side of the C-shaped profile.

[0011] Preferably, the C-shaped profile, the first connecting frame, and the second connecting frame are made of cold-rolled steel plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] First, reinforcing ribs increase the rigidity of the C-profiles, making them more stable under stress and effectively preventing bending or deformation. Combined with the X-frame, two C-profiles are connected to form a stable triangular structure, effectively preventing deformation or damage caused by excessive local stress on the frame, thus enhancing the overall stability of the frame. Second, counterweights increase the weight of the fixed base and the bottom of the frame, lowering the overall center of gravity of the power cabinet and improving its anti-tipping ability. This effectively prevents the power cabinet from tipping over under external forces (such as wind or collisions), thereby improving the stability of the frame.

[0014] Second, the combination of the positioning column and spring allows operators to easily adjust the position of the mounting block by pulling the positioning column. This enables flexible adjustment of the mounting block's position according to the equipment's installation requirements, reducing the time cost of post-installation position adjustments and thus improving the flexibility of the frame. The shock-absorbing pads absorb external impact forces from the power cabinet, reducing the impact of vibration on the internal equipment and effectively preventing loosening or damage to internal wiring. This extends the service life of the electrical equipment and ensures stable operation. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, a structurally stable power cabinet frame includes a fixed base 1, which is fixed to the bottom surface of several C-shaped profiles 2. Two first connecting brackets 3 are threaded between adjacent C-shaped profiles 2, and two second connecting brackets 4 are threaded onto the two first connecting brackets 3. A mounting bracket 5 is threaded between the two second connecting brackets 4. A support assembly is provided above the fixed base 1 to support the C-shaped profiles 2. The support assembly includes two X-shaped brackets 6, which are respectively fixed between the several C-shaped profiles 2. The bottom surface of the X-shaped brackets 6 is flush with the top surface of the fixed base 1. The top surface of the fixed base 1 is fixed with several reinforcing ribs 7, which correspond to the C-shaped profile 2. The inner wall of the C-shaped profile 2 is fixed with a limit strip 8. The inner wall of the C-shaped profile 2 is snapped with a connecting plate 9. The top surface of the connecting plate 9 is provided with several limit holes 10. The reinforcing ribs 7 are slidably connected to the limit holes 10. The connecting plate 9 is threadedly connected to the inner wall of the C-shaped profile 2. The top surface of the fixed base 1 is threadedly connected with several support blocks 11, which are threadedly connected to the C-shaped profile 2. The top surface of the fixed base 1 is provided with two mounting grooves 12, and the inner wall of the mounting grooves 12 is provided with counterweights 13.

[0022] During use, the stiffener 7 increases the rigidity of the C-profile 2, making it more stable under stress and effectively preventing bending or deformation. With the cooperation of the X-frame 6, the two C-profiles 2 are connected together to form a stable triangular structure, effectively preventing deformation or damage caused by excessive local stress on the frame, thus enhancing the overall stability of the frame. The counterweight 13 increases the weight of the fixed base 1 and the bottom of the frame, lowering the overall center of gravity of the power cabinet and improving its anti-tipping ability. This effectively prevents the power cabinet from tipping over under external forces (such as wind or collisions), thereby improving the stability of the frame.

[0023] like Figures 1-4 As shown, the top and bottom surfaces of the mounting bracket 5 are provided with sliding grooves 14. The inner wall of the sliding groove 14 is provided with several positioning grooves 15. The inner wall of the sliding groove 14 is slidably connected to the mounting block 16. The top surface of the mounting block 16 is provided with a positioning hole 17, which corresponds to the positioning groove 15. The inner wall of the positioning hole 17 is slidably inserted with a positioning post 18, which extends into the positioning groove 15. The outer wall of the positioning post 18 is wrapped with a spring 19. The bottom end of the spring 19 is fixed to the inner wall of the positioning hole 17, and the top end of the spring 19 is fixed to the outer wall of the positioning post 18. A shock-absorbing pad 20 is fixed to one side of the C-shaped profile 2. The C-shaped profile 2, the first connecting bracket 3, and the second connecting bracket 4 are made of cold-rolled steel plate.

[0024] During use, the positioning column 18 and spring 19 work together to allow operators to easily adjust the position of the mounting block 16 by pulling the positioning column 18. This allows operators to flexibly adjust the position of the mounting block 16 according to the installation requirements of the equipment, reducing the time cost of post-installation position adjustments and thus improving the flexibility of the frame. The shock-absorbing pad 20 absorbs external impact forces from the power cabinet, reducing the impact of vibration on the internal equipment and effectively preventing loosening or damage to the internal wiring, thereby extending the service life of the electrical equipment and ensuring stable operation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
