Technical Field
[0001] This utility model relates to the field of metal bases, specifically to an integrated metal lower frame for industrial equipment. Background Technology
[0002] Existing industrial equipment metal lower frames are largely uniform in terms of structural adaptability and surface functionality, with little innovation. The legs generally adopt a single-direction design, i.e., vertically downward. This necessitates the addition of adjustment accessories for different installation scenarios, increasing assembly costs and resulting in poor adaptability to diverse installation requirements.
[0003] Meanwhile, the surface treatment of each plane of the frame lacks targeted treatment, and most of them are not uniformly painted, mainly serving the purpose of corrosion prevention, with a relatively simple function. Utility Model Content
[0004] The problem to be solved by this utility model is to provide an integrated metal lower frame for industrial equipment.
[0005] To solve the above problems, this utility model provides an integrated metal lower frame for industrial equipment. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: An integrated metal lower frame for industrial equipment includes: a flat base plate; legs integrally extending from the lower surface of the flat base plate, the legs including a plurality of straight legs and a plurality of angled legs; a conductive oxide layer, the upper surface of the flat base plate having a support surface, the straight legs being directly below the support surface, the bottom surfaces of the straight legs, the bottom surfaces of the angled legs, and the side surfaces of the flat base plate all having a conductive oxide layer; wherein, the plurality of straight legs are arranged in a straight line along one side of the flat base plate, and the plurality of angled legs are arranged in a straight line along the other side of the flat base plate, the length direction of the straight legs is vertical, the length direction of the angled legs forms an angle with the vertical line, and the projection of the flat base plate along a direction perpendicular to its own plane does not intersect the bottom surface of the angled legs.
[0006] As a further improvement of this utility model, the conductive oxide layer on the side of the flat bottom plate includes a first conductive oxide layer located on the same side edge of the flat bottom plate as the straight support leg, and a second conductive oxide layer located on the vertically adjacent surface of the first conductive oxide layer; the conductive oxide layers on the bottom surface of the straight support leg and the bottom surface of the inclined support leg are a third conductive oxide layer.
[0007] As a further improvement of this utility model, each straight support leg has a corresponding horizontal support surface directly above it, all support surfaces coincide on the same horizontal plane, and each support surface has a recessed internal thread blind hole.
[0008] As a further improvement of this utility model, the upper surface of the flat bottom plate has a straight groove, and the straight groove and the inclined support are both located on the same side edge of the flat bottom plate.
[0009] As a further improvement of this utility model, the side wall of the inclined support leg is provided with several weight-reducing holes.
[0010] As a further improvement of this utility model, the side wall of the straight support leg is integrally fixed with transverse ribs and longitudinal ribs, and the transverse ribs and longitudinal ribs are integrally connected to the lower surface of the flat bottom plate, and the transverse ribs and longitudinal ribs are perpendicular to each other.
[0011] As a further improvement of this utility model, the bottom of the inclined support leg has a vertical through hole.
[0012] As a further improvement of this utility model, the flat bottom plate and the support legs are coated with fluoropolyurethane matte enamel on the parts outside the conductive oxide layer.
[0013] As a further improvement of this utility model, the coating thickness of the conductive oxide layer is 5 to 15 μm, and the surface roughness Ra of the conductive oxide layer is less than 1.6 μm.
[0014] The beneficial technical effects of using the integrated metal lower frame of the industrial equipment of this application are: By combining straight and angled supports and designing them in different directions, it can adapt to various installation scenarios. The outward-extending angled supports provide stronger anti-tipping capabilities. The straight supports do not protrude from the side facade of the lower frame, which facilitates the lower frame to fit snugly against the side facade of other external components.
[0015] The flat base and legs adopt an integrated extended structure, which strengthens the overall structure, enhances the load-bearing capacity and stability of the frame, and avoids the potential loosening of spliced structures.
[0016] Conductive oxide layers are specifically applied to the bottom surfaces of straight supports, inclined supports, and the side facades of flat base plates. This not only enhances the corrosion resistance of key contact areas and facades but also imparts conductivity, solving the problem of limited surface treatment functionality in traditional frames and improving surface functionality and reliability.
[0017] The conductive oxide layer on the bottom of the support feet can ensure the equipment is connected to the grounding platform in scenarios such as electronic equipment and new energy battery assembly, quickly release static electricity to avoid component damage or fire risk, and resist corrosion from moisture, electrolyte, etc., thus extending the life of the support feet.
[0018] The conductive oxide layer on the side facade of the lower frame can discharge static electricity in the working environment, prevent dust adsorption from affecting accuracy, and also block oil stains to avoid corrosion of the side facade and ensure equipment stability.
[0019] Because the integrated metal lower frame is also made of conductive metal, it can create directional conductive channels. The conductive oxide layer on the bottom of the legs and the side facades allows static electricity and interference currents to flow through the bottom of the legs to the inside of the frame, and then to the side facades, thus being discharged in an orderly manner. This prevents random current conduction from affecting the internal components of the equipment, making it suitable for industrial scenarios requiring anti-static protection. The insulating paint on the parts outside the conductive oxide layer can isolate external stray currents and electromagnetic interference, and also protect non-critical parts of the frame from corrosion, thus balancing conductive functionality with the protection of non-conductive areas.
