Connection structure of rigid pipe and flexible pipe

The invention discloses a connection structure of a rigid pipe and a flexible pipe, and relates to the technical field of connection parts. The connection structure of the rigid pipe and the flexiblepipe comprises the rigid pipe, the flexible pipe and positioning parts, wherein first grooves are formed in an outer wall of the rigid pipe; the rigid pipe is sleeved with the flexible pipe, second grooves are formed in an inner wall of the flexible pipe, and the first grooves and the second grooves are oppositely formed, and together form connection channels; and the connection channels are filled with the positioning parts so that opposite movements of the rigid pipe and the flexible pipe can be limited. No clamps need to be fixed to the outer portion of the provided connection structure ofthe rigid pipe and the flexible pipe, and the provided connection structure of the rigid pipe and the flexible pipe can be assembled even in a narrow space, and is high in stability after being assembled. 本发明公开一种刚性管与软管的连接结构，涉及
