Description

Technical Field

[0001] This utility model relates to the field of cabinet structure, and in particular to a detachable modular cabinet assembly structure for power and weak current electrical cabinets. Background Technology

[0002] Box-type enclosures are mainly used to house electrical cables and components. Multiple enclosures are combined to form an integrated cabinet, which is now widely used in the field of power and low voltage electrical cabinet equipment.

[0003] Currently, traditional complex box-type enclosures are manufactured and welded together from five parts (left shell, right shell, upper shell, lower shell, and rear shell). The production process is complex, involves many steps, has a long production cycle, low efficiency, wastes materials, equipment, and labor costs. Furthermore, because each panel is welded and assembled, it cannot be disassembled, making it unsuitable for various mounting and fixing cabinets. In addition, when expansion is needed, the bottom and top frames cannot be freely disassembled and reassembled.

[0004] In view of this, this technical solution proposes a detachable modular enclosure assembly structure for strong and weak current motor cabinets. It adopts a detachable frame structure with detachable frame plates assembled on both sides of an integrated "U" shape, realizing a detachable frame with an opening on one side and enclosed top and bottom surfaces. The production process is simple, the cycle is short, and the adaptability is strong. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related technologies. Therefore, the main objective of this invention is to provide a detachable modular enclosure assembly structure for power and weak current motor cabinets, aiming to solve the problems of complex manufacturing processes, long production cycles, and poor assembly adaptability of existing box-type enclosures.

[0006] To achieve the above objectives, this utility model provides a detachable modular enclosure assembly structure for power and communication equipment cabinets, comprising a U-shaped frame formed by integral bending, and a cabinet body jointly enclosed by a top plate and a bottom plate. The U-shaped frame has inner frame borders on both sides of the opening near the top plate, and inner frame borders have inner frame border holes. The top plate has outer frame borders on both sides corresponding to the inner frame borders, and outer frame borders have through holes corresponding to the inner frame border holes. After assembly, the interior of the outer frame borders is tightly attached to the exterior of the inner frame borders. The bottom plate is located on the opposite side of the top plate, and the bottom plate has inner frame borders on both sides. The U-shaped frame has corresponding fixing holes on both sides of the opening near the bottom plate and on both sides of the inner frame borders. After assembly, the bottom plate is aligned with both ends of the U-shaped frame.

[0007] As a further embodiment of this utility model, one end of the inner frame is provided with an ear piece that extends vertically into the U-shaped frame.

[0008] As a further improvement of this utility model, the ear piece is provided with a spare hole.

[0009] As a further embodiment of this utility model, the U-shaped frame extends vertically outward on both sides of the opening after being assembled with the top plate and the bottom plate to form a folded edge with holes.

[0010] As a further improvement of this utility model, the number of through holes and inner edge holes arranged vertically in sequence is at least four.

[0011] As a further embodiment of this utility model, both the top plate and the bottom plate are integral sheet metal bending and drilling structures identical to the U-shaped frame.

[0012] The beneficial effects of this utility model are as follows: This solution uses a U-shaped frame, top plate, and bottom plate formed by one-piece bending to create a detachable box body, which improves the production process and assembly efficiency.

[0013] Specifically, the U-shaped frame, molded as a single piece, combined with standardized sheet metal bending and perforation of the top and bottom plates, replaces traditional welding processes, shortening the production cycle. During assembly, the outer frame of the top plate is tightly fitted against the outer edge of the inner frame of the U-shaped frame, and fixed by at least four vertical through holes aligned with the inner frame holes, forming a stable structure with multi-point distributed stress, avoiding the risk of single-point deformation. The raised design of the top plate facilitates internal wiring and door installation. The bottom plate is assembled flush with the fixing holes of the inner frame and U-shaped frame, ensuring load-bearing stability. Additional lugs and spare holes support tool-less quick adaptation of different top plate models, while pre-drilled holes at the opening of the U-shaped frame allow for immediate door installation. The overall structure gives the enclosure high compatibility and strong load capacity, perfectly adapting to scenarios with high-voltage loads and frequent expansion of low-voltage systems, completely solving the problems of complex traditional processes, poor adaptability, and difficulty in expansion.

[0021] 1 Box body 11 roof 10 U-shaped frame 110 outer frame 100 Inner border 111 Through hole 101 Inner edge hole 12 base plate 102 ear 120 Inner frame 103 spare hole 121 Fixing hole 104 Folded edge Detailed Implementation

[0022] as follows: Please see the appendix Figure 1-6 , The main structure of this design includes an integrally bent U-shaped frame 10, and a box body 1 formed by a top plate 11 and a bottom plate 12. In terms of structural assembly, the U-shaped frame 10 has inner frame borders 100 on both sides of the opening near the top plate 11, with inner frame border holes 101 on the inner frame borders 100. The top plate 11 has corresponding outer frame borders 110 on both sides, with through holes 111 corresponding to the inner frame border holes 101 on the outer frame borders 110. During assembly, the inner side of the outer frame borders 110 of the top plate 11 is tightly fitted against the outer side of the inner frame borders 100 of the U-shaped frame 10, and is aligned and fixed by the through holes 111 and the inner frame border holes 101. This causes the top plate 11 to bulge upwards after assembly, facilitating the later installation of doors or internal wiring. The base plate 12 is located on the opposite side of the top plate 11. Inner frames 120 are provided on both sides of the base plate 12. The inner edges of the U-shaped frame 10 near the opening of the base plate 12 and the inner frames 120 are provided with corresponding fixing holes 121. After assembly, the base plate 12 and the U-shaped frame 10 are aligned at both ends, and the inner frames 120 are fitted inside the U-shaped frame 10 and fixed by the fixing holes 121, ensuring the base plate 12 is stably placed. The entire assembly process of this structure is completed through simple hole alignment and fitting, without welding or other complex processes. Ultimately, only one opening facing the operator is retained, facilitating use and maintenance.

[0023] This technical solution simplifies the enclosure production process. Since the U-shaped frame 10 is integrally bent, the number of parts and welding requirements are reduced, shortening the production cycle and lowering costs. During assembly, the outer frame 110 of the top plate 11 fits tightly with the inner frame 100, and the inner frame 120 of the bottom plate 12 aligns with the fixing holes 121, making the enclosure easy to disassemble and reassemble, improving adaptability, and allowing flexible application to various power and weak current motor cabinet scenarios. After assembly, the upward protrusion of the top plate 11 facilitates equipment wiring and door installation, while the flush structure of the bottom plate 12 enhances overall stability and durability, solving the problems of complex, inefficient, and difficult-to-expand traditional processes.

[0024] Referring to Figure 2, a preferred embodiment of this utility model is as follows: Preferably, this solution adds an ear piece 102 extending vertically into the U-shaped frame 10 at one end of the inner frame 100. When it is necessary to adapt to top plates 11 (outer frame 110) of different models or sizes, if the original inner frame hole 101 cannot be aligned with the through hole 111 of the top plate 11, holes can be drilled on-site in the spare area of ​​the ear piece 102 to form a new fixing point.

[0025] In practical operation, for example, operators only need to drill holes after positioning the ear piece 102 against the outer frame 110 of the top plate 11. This allows the newly added holes to form a double fixation with the inner edge hole 101, retaining the original fixing function of the inner edge hole 101 while enabling cross-size adaptation through the new holes on the ear piece 102, thus improving the compatibility of the enclosure with top plates 11 of different specifications. There is no need to prefabricate multiple specifications of components; the problem of model differences is solved through a single standardized ear piece 102 structure, significantly reducing production complexity and warehousing costs.

[0026] Reference Appendix Figure 2 In a preferred embodiment of this utility model, an additional spare hole 103 is provided on the ear piece 102, which further enhances the adaptability.

[0027] Specifically, when different models of top plates 11 need to be installed, if the original inner edge hole 101 is misaligned with the through hole 111 of the top plate 11, the operator can directly use the spare hole 103 on the ear piece 102 as a prefabricated fixing point, and directly lock the outer frame 110 of the top plate 11 to the spare hole 103 with bolts. There is no need for on-site drilling. By using the prefabricated spare hole 103, the steps of temporary positioning and drilling are eliminated, thus improving assembly efficiency.

[0028] It should be understood that the spare hole 103 can be a standard hole diameter design that can be matched with universal fasteners to ensure that the connection strength is consistent with the original structure.

[0029] Reference Appendix Figure 2In a preferred embodiment of this utility model, preferably, after the U-shaped frame 10 is assembled with the top plate 11 and the bottom plate 12, outwardly extending vertically folded edges 104 are added on both sides of the opening, and the folded edges 104 have holes, mainly for possible door assembly later.

[0030] Specifically, since the folded edge 104 is directly extended from the main body of the U-shaped frame 10, no additional welding bracket is required. Its holes can be used as prefabricated installation positions for door hinges or locks. Operators only need to directly align and fix the door structure with the holes of the folded edge 104 to quickly complete the door assembly on the opening side of the box.

[0031] It should be understood that the outward extension of the folded edge 104 avoids occupying internal space of the box, ensuring the internal design. The layout remains undisturbed, and standardized holes allow for the immediate installation and use of universal door accessories, reducing the cost of customized modifications. This is especially suitable for electrical and weak current applications that require frequent adjustments to door configurations.

[0032] Reference Appendix Figure 2 In a preferred embodiment of this utility model, the through hole 111 and the inner edge hole 101 can be set to at least four, mainly to significantly improve the connection strength between the top plate 11 and the U-shaped frame 10 by increasing the density of fixing points. These holes are evenly distributed in the vertical direction, so that the contact surface between the outer frame 110 of the top plate 11 and the inner edge 100 of the U-shaped frame 10 forms a force. When the box is under load or vibrated, the pressure is distributed to at least four bolt fixing points to avoid deformation.

[0033] Reference Appendix Figure 1 , 2 In a preferred embodiment of this utility model, the top plate 11 and bottom plate 12 of this solution adopt the same integrated sheet metal bending and drilling process as the U-shaped frame 10, which improves production efficiency and component compatibility. Since all three are formed by bending a single sheet metal piece and pre-drilling holes, the time-consuming process and deformation risk of traditional multi-part welding are eliminated. This ensures that the through holes 111 of the outer frame 110 of the top plate 11, the fixing holes 121 of the inner frame 120 of the bottom plate 12, and the inner edge holes 101 and folded edge holes 104 of the U-shaped frame 10 maintain completely consistent processing precision. During assembly, all holes automatically align without manual adjustment, shortening the production cycle of individual components. This makes the top plate 11, bottom plate 12, and U-shaped frame 10 completely interchangeable. That is, when the enclosure needs expansion or repair, any damaged component can be directly replaced by a standardized product from the same batch, significantly reducing maintenance costs. The integrated molding structure avoids the problem of weakened metal strength caused by welding, improving the overall load-bearing capacity and vibration resistance of the enclosure.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the present utility model's technical concept and the contents of the present utility model's technical solution specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
