The invention relates to an arc-shaped corner structure applied to household products. The arc-shaped corner structure is characterized by comprising an arc-shaped corner component and a composite supporting leg component, wherein the arc-shaped corner component further comprises a plurality of sector-shaped pure log assembling blocks, a screw and nuts, through holes allowing the screw to penetrate through are formed in all the sector-shaped assembling blocks, the sector-shaped assembling blocks are stacked, glued and pressed together, the screw penetrates through the through holes in the sector-shaped assembling blocks, and the nuts are screwed up at two ends of the screw, so that all the sector-shaped assembling blocks are firmly locked to form an arc-shaped corner component body adopting an integral structure; the composite supporting leg component comprises a main supporting leg assembly and an auxiliary supporting leg assembly which are fixedly connected with each other. The corner structure is low in machining difficulty, high in utilization rate of raw wood materials, low in production cost, capable of effectively avoiding adverse factors such as cracking, deformation and the like due to expansion caused by heat and contraction caused by cold, good in quality and long in service life, and wood with large diameters and large tree ages is not required.
