Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, and in particular relates to a switch cabinet. Background Technology

[0002] Switchgear is a core electrical device in power distribution systems used for power distribution, circuit control, and fault protection. It is widely used in industrial production, building power distribution, substations, and other scenarios. Internally, it integrates various electrical components such as circuit breakers, fuses, and metering instruments to achieve on / off control, overload protection, and power metering functions for the power supply circuit. As the main load-bearing structure of the switchgear, the structural strength and assembly stability of the cabinet directly determine the installation accuracy of the internal electrical components and the reliability of equipment operation. In existing technologies, most switchgear cabinets are assembled from a profile frame combined with side panels, back panels, and cabinet doors. The side panels are typically single-layer thin-plate structures, detachably installed to the side of the profile frame using fasteners. In practical applications, when the cabinet is large and the side panels are wide, the deformation resistance of a single side panel is limited. Under external impact, internal equipment load, or long-term stress, the side panels are prone to deformation problems such as surface dents and edge warping. This not only affects the sealing performance and appearance consistency of the cabinet, but may also cause the internal electrical mounting brackets to shift, interfering with the normal assembly and operation of electrical components. To improve the strength of the side panels, some existing solutions increase the thickness of the side panel material to enhance deformation resistance, but this significantly increases the overall weight of the cabinet and material costs. Other solutions use reinforcing ribs welded to the inside of the side panels, but the welding process is cumbersome, positioning is difficult when multiple ribs are spliced ​​together, and assembly production efficiency is low. Utility Model Content

[0003] The purpose of this utility model is to provide a switch cabinet to solve the aforementioned technical problems.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0013] Example 1:

[0014] This embodiment provides a switch cabinet, including a profile frame 1, a back panel, two side panels 2, and a cabinet door. The back panel and the two side panels 2 are detachably mounted on the profile frame 1, and the cabinet door is rotatably mounted on the profile frame 1. The side panels 2 are further provided with a reinforcing component 3, which includes: A plurality of first ribs 31 are connected to the side plate 2 and arranged along the X direction, and the plurality of first ribs 31 are arranged at equal intervals along the Z direction; The second rib plate 32 has a plurality of second slots 321 arranged equidistantly along the Z-direction. A plurality of connectors 33, wherein each connector 33 includes a first connecting part 331 and a second connecting part 332 of an integral structure, the first connecting part 331 is disposed along the X direction and connected to the first rib 31, and the second connecting part 332 is disposed along the Z direction and connected to the second rib 32. Among them, several first ribs 31 are respectively inserted into several second slots 321 on the second ribs 32.

[0015] In this technical solution, this embodiment provides a switch cabinet, with a profile frame 1 as the overall load-bearing skeleton of the cabinet. The back panel and two side panels 2 are respectively installed on the rear and left and right sides of the profile frame 1 by bolted detachable structures. The cabinet door is assembled to the front edge of the profile frame 1 through a hinge shaft, and can rotate relative to the profile frame 1 around the hinge shaft to realize the opening and closing of the front opening of the cabinet. In order to improve the structural rigidity of the side panels 2 and prevent the side panels 2 from deforming under the action of external forces or internal loads, a reinforcing component 3 is provided on the side of each side panel 2 facing the inside of the cabinet. The reinforcing component 3 forms a multi-point support and stress dispersion for the side panel 2 through a structure of cross splicing of transverse and longitudinal ribs.

[0016] The first rib 31 is a long, flat plate. The first rib 31 is welded and fixed to the side plate 2. Its function is to provide lateral support to the side plate 2 along the X direction of the cabinet, disperse the lateral stress on the side plate 2, and improve the bending resistance of the side plate 2. The length of the first rib 31 extends along the X direction of the cabinet, and multiple first ribs 31 are arranged parallel to each other and at equal intervals along the Z direction of the cabinet. The second rib 32 is a long, straight strip. Its function is to provide longitudinal support to the side panel 2 along the Z-direction of the cabinet, and simultaneously intersect with the first rib 31 perpendicularly to form a grid-like support system, dispersing the external force on the side panel 2 both laterally and longitudinally to avoid stress concentration. The length of the second rib 32 extends along the Z-direction of the cabinet, and several second slots 321 are equally spaced along the height direction on the second rib 32, allowing the first rib 31 to be embedded into the corresponding second slots 321. Furthermore, there are several second ribs 32 arranged equally at intervals along the X-direction, with multiple second ribs 32 arranged parallel and equally spaced along the front-rear direction of the cabinet to form a grid support structure.

[0017] Furthermore, the first rib 31 is also provided with a plurality of first slots 311, which are used for insertion and engagement with the second slots 321. The first slots 311 are used to form an insertion and engagement with the second rib 32 and the connector 33. The first slots 311 and the second slots 321 are interlocked and fitted together. The inner sidewalls of the slots abut against and fit against the groove walls of the corresponding ribs, thereby achieving vertical insertion and positioning between the second rib 32 and the first rib 31. The cross splicing of the two effectively improves the structural tightness after splicing and enhances the connection stability.

[0018] The connector 33 is a plate-shaped component formed by stamping, including a first connecting part 331 and a second connecting part 332. The two connecting parts are arranged at a mutually perpendicular angle, and the overall cross section is L-shaped. Its function is to connect the intersection of the first rib 31 and the second rib 32, strengthen the structural stability of the insertion part, limit the relative displacement between the two ribs, and prevent the intersection from being misaligned or loosened when under stress.

[0019] In actual operation, when the side panel 2 of the switchgear is subjected to external impact or load from internal equipment, the external force is first transmitted from the side panel 2 body to the first ribs 31 fixedly connected to it. The first ribs 31, arranged horizontally, disperse the external force in the front-to-back direction, preventing excessive local stress and deformation of the side panel 2. The second ribs 32, which are perpendicularly fitted to the first ribs 31, further disperse the stress transmitted laterally in the height direction, so that the external force is evenly transmitted in the cross-grid support structure, greatly improving the overall deformation resistance of the side panel 2. The connectors 33 set at each intersection node form a locking reinforcement for the plug-in structure, restricting the relative movement between the first ribs 31 and the second ribs 32, preventing the ribs from disengaging or misaligning under repeated stress or large external forces, ensuring that the grid support structure maintains a stable support state for a long time, and continuously reinforcing the side panel 2.

[0020] Example 2:

[0021] This embodiment provides a switch cabinet, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] Furthermore, the connector 33 is also provided with a connecting groove 333, which is used to engage with the first slot 311. By providing a connecting groove 333 at the included angle of the connector 33, and the connecting groove 333 extending along the thickness direction of the connector 33, the connector 33 is assembled at each intersection of the first rib 31 and the second rib 32. The connecting groove 333 is embedded in the first slot 311 on the first rib 31 to form a locking, thereby positioning the connector 33 at the intersection. This provides a positioning function for the installation and fixation of the connector 33, facilitating assembly. It also limits the offset between the first rib 31 and the second rib 32, locking the intersection into a more stable overall structure.

[0023] Furthermore, the length of the first slot 311 along the X direction is 'a', the width of the second connecting part 332 along the X direction is 'b', and the width of the second rib 32 along the X direction is 'c', where a = b + c. This structural design ensures that at the intersection of the first rib 31 and the second rib 32, the first rib 31, the second rib 32, and the connecting member 33 remain tightly fitted, preventing relative movement during assembly and making the positioning of the assembly connection more accurate. This effectively ensures the structural integrity and stress stability of the reinforced component 3 after assembly. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many other forms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
