Snake bone structure convenient to assemble and maintain

Abstract

The invention discloses a snake bone structure convenient to assemble and maintain, and relates to the technical field of snake bone structure devices. The snake bone structure comprises a plurality of ball joint units, a front ball joint, a rear ball joint and four pull ropes, wherein the plurality of ball joint units, the front ball joint and the rear ball joint are provided with connecting cylinders respectively; the two ends of the plurality of connecting cylinders are fixedly provided with incomplete spherical blocks and hemispherical blocks respectively; a plurality of connecting blocksare uniformly fixedly mounted at one side of each of the plurality of hemispherical blocks; and one end of each of the plurality of connecting blocks is fixedly connected with a triangular clamping piece. The snake bone structure is reasonable in structure and simple to operate, the plurality of ball joint units are sequentially connected with one another, so that the hemispherical blocks can rotate at any angle within a certain range along with the plurality of triangular clamping pieces along the incomplete spherical blocks, bending deformation at more angles is realized, the application range is enlarged, multi-angle free rotation is realized, and the snake bone structure has the advantages of being convenient to disassemble and assemble, good in anti-falling effect and the like.

Description

technical field [0001] The invention relates to the technical field of snake-bone structure devices, in particular to a snake-bone structure that is convenient for assembly and maintenance. Background technique [0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has image sensors, optical lenses, light source lighting, and mechanical devices. Medical endoscopes can pass through the mouth. Entering the stomach or entering the body through other natural channels, the endoscope can be used to see the lesions that cannot be displayed by X-rays, and the industrial endoscope can bend into some internal spaces that cannot be directly seen to check the internal structure, and there are many snake bone structures The application of endoscope pipeline components. [0003] In the prior art, the snake bone structure usually adopts a rotating shaft and a bayonet socket on a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the snake bone structure usually adopts a rotating shaft and a bayonet socket on a circular tubular connecting unit, and multiple connecting units are connected to each other and rotate on the bayonet socket through the rotating shaft to realize a flexible connection in which multiple connecting units can rotate at a certain angle. However, this connection method can only make the connection unit rotate in a certain direction, and cannot realize multi-angle free rotation, which limits the scope of application of related equipment

[0004] In the prior art, in order to achieve multi-angle free rotation and reliable detachment between multiple connecting units at the same time, it often leads to increased difficulty in disassembly and assembly of the structure, and increased difficulty in manufacturing and maintenance.
