A snake-bone structure for easy assembly and maintenance

Abstract

The invention discloses a snake bone structure that is convenient for assembly and maintenance, relates to the technical field of snake bone structure devices, and includes a plurality of ball joint units, a front ball joint, a rear ball joint and four pull ropes, a plurality of said The ball joint unit, one of the front ball joints and one of the rear ball joints are all equipped with connecting cylinders, and the two ends of the multiple connecting cylinders are respectively fixed with incomplete spherical blocks and hemispherical blocks. One side of each of the hemispherical blocks is uniformly fixed with a plurality of connection blocks, and one end of the plurality of connection blocks is fixedly connected with a triangular clip. The present invention has reasonable structure and simple operation. Multiple ball joint units are sequentially connected to each other, so that the hemispherical block can be rotated at any angle within a certain range along with multiple triangular clips along the incomplete ball block, so as to realize bending deformation of more angles. , increase the scope of application, and it not only realizes multi-angle free rotation, but also has the advantages of convenient disassembly and assembly, and good anti-off effect.

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 an image sensor, optical lens, light source lighting, mechanical devices, etc. Enter the stomach or enter the body through other natural orifices. The endoscope can be used to see the lesions that cannot be displayed by X-rays. The industrial endoscope can be bent into some internal spaces that cannot be seen directly, and the internal structure can be viewed. There are many snake bone structures. application on endoscope tube parts. [0003] In the prior art, the serpentine structure usually adopts a circular tubular connecting unit to set a rotating shaft and a bayonet, and a plurality of connecti...

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.
