Leakage-proof automatic splicing device for concrete formworks

The invention discloses a leakage-proof automatic splicing device for concrete formworks, and belongs to the technical field of concrete formworks, the surface of a first formwork and the surface of a second formwork are each provided with a first receding groove and a second receding groove, the interior of each first receding groove is rotationally connected with a hanging plate through a shaft rod, and the inner wall of each second receding groove is in contact connection with a supporting box; according to the leakage-proof automatic splicing device for the concrete formworks, through the arrangement of an electric telescopic rod, a rotating seat, a hanging ring, a hanging plate and a hanging rod, the splicing positions of the first formwork and the second formwork can be quickly and automatically spliced and fastened, the labor intensity of a user is greatly reduced, the splicing efficiency is improved, and the practicability is high. And through arrangement of a supporting box, a limiting base and a baf
