Snake bone connecting structure for endoscope

Abstract

The invention discloses a snake bone connecting structure for an endoscope. The snake bone connecting structure comprises a plurality of snake bone joints, wherein a buckling structure and a limitingpart are arranged at the end of each snake bone joint, and each buckling structure comprises a first buckling structure body and a second buckling structure body; each first buckle structure and the corresponding second buckle structure extend outwards from the upper and lower peripheries of the two corresponding side surfaces of the snake bone joint, and the first buckling structure and the buckling buckle structure of the same snake bone joint form a rotation center; and each first buckling structure and the corresponding second buckling structure are asymmetrically arranged, and the adjacent snake bone joints are connected through a connecting pair of a hinge structure formed by matching the buckling structures with the limiting parts. The limiting has the beneficial effects that the snake bone joints can be connected together through cooperation of the buckling structures and the limiting parts, it is guaranteed that the whole structure of the snake bone joints is bent normally andcannot be disengaged, and the double-buckling-position structure enables the snake bone joints to be bent more stably.

Description

technical field [0001] The invention relates to the technical field of snake bone connection structures, in particular to a snake bone connection structure for an endoscope. Background technique [0002] The snake bone used on the endoscope at present is a whole formed by riveting the multi-section snake bone segments. [0003] Patent application number 201711069863.4 discloses a connection structure of snake bones, including a connection structure A and a connection structure B. The connection structure A includes a limiting groove and a connecting piece, and the limiting grooves are distributed on both sides of the connecting piece. The connecting structure B includes a connecting groove and a limiting block, the limiting blocks are distributed on both sides of the connecting groove, the connecting groove matches the connecting piece, the limiting groove matches the limiting block, and the connecting When the structure A is connected with the connection structure B, an in...
