Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically to an integrated control cabinet. Background Technology

[0002] Integrated control cabinets are core equipment in industrial automation, power distribution, and building intelligence. They house a large number of electrical components, including programmable logic controllers (PLCs), circuit breakers, contactors, frequency converters, and various terminal blocks. Traditional control cabinets typically employ a fixed backplane structure, where the backplane for mounting these electrical components is rigidly connected to the inside of the cabinet frame via welding or bolts. This design is simple and low-cost, and was widely used in the early days.

[0003] However, with increasing system complexity and equipment integration density, the inherent drawbacks of traditional fixed backplanes are becoming increasingly apparent. Firstly, during the assembly, wiring, and commissioning phases of the control cabinet, the backplane is deeply embedded inside the cabinet, severely limiting the operator's working space and obstructing their view. This makes component installation, cable laying and connection, and subsequent testing and maintenance extremely difficult, significantly reducing production efficiency and easily leading to wiring errors or component damage due to operational inconvenience. Secondly, when it is necessary to repair or upgrade equipment already in operation, technicians often have to spend long periods crouched in front of the cabinet door or leaning inside to work, which not only burdens the operators physically and mentally but also poses significant safety hazards.

[0004] To address the aforementioned issues, some improved solutions have emerged in existing technologies, such as using fully removable drawer-type modules. However, these solutions are typically complex in structure and expensive to manufacture, and primarily target standardized functional modules that are self-contained, making it difficult to flexibly adapt to non-standard backplanes that require overall layout and dense wiring. Therefore, the industry urgently needs a new backplane fixing solution that is relatively simple in structure, cost-controllable, and can significantly improve the convenience of installation and maintenance of equipment inside the control cabinet. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an integrated control cabinet, including a cabinet body and a back panel for installing electrical components. Horizontally distributed crossbars are fixed on the inner walls of opposite sides inside the cabinet body. The two sides of the back panel are movably connected to the crossbars on both sides through a sliding connection mechanism. The sliding connection mechanism includes a slider that slides with the crossbars and a bracket that connects the slider to the side of the back panel.

[0006] Furthermore, the crossbar is provided with a slide rail extending along its length, and the slider is slidably disposed within the slide rail.

[0007] Furthermore, the slide is a long groove, and the shape of the slider is adapted to the long groove and accommodated therein.

[0008] Furthermore, the sliding connection mechanism also includes a positioning component for fixing the back plate at a certain position on the crossbar.

[0009] Furthermore, the positioning component includes an elastic element and a limiting element. The crossbar has a plurality of positioning holes spaced apart along its length. The limiting element selectively engages with the positioning holes under the drive of the elastic element.

[0010] Furthermore, the elastic element is a spring, and the limiting element is a limiting pin.

[0011] Furthermore, the card holder is fixedly connected to the side of the back plate by fasteners.

[0012] Furthermore, the crossbar and the back plate are arranged perpendicular to each other.

[0013] Furthermore, this utility model has the following beneficial effects: (1) With this invention, the operator can easily pull the entire back panel outwards, bringing it closer to or even partially moving it out of the cabinet door area. This allows the operator to work on all electrical components on both sides of the back panel in a comfortable posture in an open and bright environment.

[0014] (2) The back panel of this utility model can slide continuously on the crossbar through the connector. The limiting pins cooperate with different round holes under the action of the spring, providing a clear "gear feel", and can accurately fix the back panel in multiple preset positions according to the size, quantity and heat dissipation requirements of the internal components, thus realizing the customization of the cabinet space layout.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Before describing the specific embodiments of this utility model in detail, it is necessary to explain the existing integrated control cabinet structure. Currently, in mainstream integrated control cabinets on the market, the back panel used for installing electrical components is usually fixed and immovable. The traditional approach is to rigidly connect the back panel directly to the inside of the cabinet frame by welding or multiple bolts. Although this fixed structure is simple to manufacture, it exposes significant drawbacks in actual use: when technicians need to install, wire, or maintain components on the back panel, the operating space is extremely narrow due to the back panel being deeply embedded inside the cabinet, obstructing the view and resulting in low work efficiency. Furthermore, the inconvenience of operation can easily lead to wiring errors or personal safety hazards. Although there are some extractable sub-module solutions, their structures are complex, costly, and difficult to apply to non-standard back panel scenarios that require overall layout and dense wiring.

[0020] To address the aforementioned problems, this utility model provides an integrated control cabinet with a sliding back panel. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] See Figures 1 to 8 The integrated control cabinet in this embodiment mainly includes a cabinet body 1, a cabinet door 2, a crossbar 3, a back panel 4, and a sliding connection mechanism 5.

[0022] The cabinet 1 forms the main frame of the control cabinet. At least two horizontal and parallel crossbars 3 are fixedly installed on the inner walls of opposite sides of the cabinet 1, for example, by welding or bolting. In this embodiment, one crossbar 3 is provided on each side, both vertically, and the length direction of the crossbar 3 is consistent with the depth direction of the cabinet 1, and is approximately perpendicular to the plane of the back panel 4.

[0023] The back panel 4 is used to install various electrical components, such as PLCs, circuit breakers, and terminal blocks. The back panel 4 is movably connected to the crossbars 3 on both sides through sliding connection mechanisms 5 provided on both sides, so that the back panel 4 can move back and forth relative to the cabinet 1.

[0024] Specifically, the sliding connection mechanism 5 is the core component for realizing the sliding function of the back plate 4. It mainly consists of a slider 501 and a holder 502. The slider 501 is slidably mounted on the crossbar 3. In a preferred embodiment, a long groove extending along its length can be formed on the crossbar 3, and the shape of the slider 501 is adapted to the long groove and accommodated within the long groove, thereby achieving smooth and stable sliding guidance.

[0025] The holder 502 is fixedly connected to the slider 501 and is used to connect the back plate 4. The holder 502 can be designed as L-shaped, U-shaped, or other structures that can clamp or conform to the side of the back plate 4. The side of the back plate 4 is fixedly connected to the holder 502 by fasteners, such as screws. Thus, when the slider 501 slides on the crossbar 3, it can drive the entire back plate 4 to move together.

[0026] To fix the back plate 4 in the desired position, the sliding connection mechanism 5 may also include a positioning assembly. One specific implementation of this positioning assembly is as follows: Multiple circular holes 301 are spaced apart along the length of the crossbar 3 as positioning holes. A deep groove 507 is formed inside the slider 501 and / or the holder 502. A limiting pin 503 and a spring 506 are disposed within the deep groove 507. The spring 506 applies a spring force to the limiting pin 503, causing its end to tend to extend out of the groove 507. When the back plate 4 moves to a specific position, the end of the limiting pin 503, under the action of the spring force, engages in the corresponding circular hole 301, achieving initial positioning of the back plate 4.

[0027] To further enhance the reliability of the fixation, especially in vibration environments, an additional locking mechanism can be provided. For example, a protrusion 504 with a groove 505 can be provided on the limit pin 503, and a square groove communicating with a deep groove 507 can be opened on the side wall of the retainer 502. When complete locking is required, the end of a U-shaped bracket can be inserted into the square groove from the outside and locked into the groove 505, thereby restricting the retraction movement of the limit pin 503 and achieving mechanical hard locking.

[0028] Brief description of the work process: When installing or maintaining electrical components, the operator can pull the back panel 4 outward, allowing it to slide along the crossbar 3 via the sliding connection mechanism 5 to a convenient operating position near the cabinet door 2. During this process, the ends of the limit pins 503 slide on the surface of the crossbar 3 and, under the action of the spring 506, sequentially engage with different round holes 301, providing a step-by-step positioning feel. After completing the work, the back panel 4 is pushed inward back into the cabinet 1 and can be finally locked using the U-shaped bracket to ensure its stability during operation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
