Abstract
The utility model discloses a snake-bone structure capable of freely rotating, which comprises a snake-bone front connection loop and a snake-bone rear connection loop.A plurality of mutually connected connection units are arranged between the snake-bone front connection loop and the snake-bone rear connection loop.A weaving net protective tube is installed outside the connection units.The connection units comprises one-way joint loops, a snake-bone A loop and a snake-bone B loop.The inner wall of the one-way joint loop is equipped with a wire rope location hole and the outer wall thereof is equipped with an extending hinged lug linked to the snake-bone A loop and the snake-bone B loop.The plurality of one-way joint loops are linked to the snake-bone A loop and the snake-bone B loop at intervals.The wire rope location holes at the inner walls of the one-way joint loops are successively penetrated by a wire rope.The snake-bone structure of the utility model is simple in structure, easy in usage and installation, low in cost and simple in process, wherein the 360-degree bending and swing is realized and the production benefit and economical and practical performances are improved.
Description
Technical field
This utility model relates generally to a kind of all-metal framing structure that can rotate freely, and relates in particular to a kind of snake bone structure that can rotate freely.
Background technology
Existing endoscope will realize the head-bent break-in, all adopt a built-in strip metal snake bone joint, the method of the control wire that is attached thereto by tractive makes its bending, and this strip metal snake bone is to save connecting axle by the pass of each joint to interconnect, axial rotation is come work again, equidirectional axle can only have the bending of positive and negative two directions, want the multi-direction connecting axle in certain several joint that then must make to be on the different positions, existing metal snake bone can only accomplish to have the structure of the bending of four direction all around, can not accomplish 360 omnidirectional bending of degree and swings, and its price height, the processing technique complexity has influenced productivity effect and economical and practical performance.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of snake bone structure that can rotate freely is provided, solve existing metal snake bone and can only accomplish to have the structure of the bending of four direction all around, can not accomplish 360 omnidirectional bending of degree and swings, and its price height, the processing technique complexity influences problems such as productivity effect and economical and practical performance.
This utility model is achieved through the following technical solutions:
A kind of snake bone structure that can rotate freely; include before the snake bone adapter ring behind the adapter ring and snake bone; be provided with the link unit that several are connected mutually between the adapter ring behind adapter ring and the snake bone before the described snake bone; it is characterized in that: described link unit is equipped with the knitmesh protecting tube outward; described link unit includes unidirectional pitch circle; Serpentis joint bone A; the B circle; described unidirectional pitch circle inwall is provided with the steel wire rope locating hole; the outer wall of described unidirectional pitch circle is provided with the hinged ear that stretches out; and with Serpentis joint bone A; B encloses link; described Serpentis joint bone A; the B coil structures is symmetrical and to being combined into one; described several unidirectional pitch circles and Serpentis joint bone A; the space link of B circle, the steel wire rope locating hole on the unidirectional pitch circle inwall is successively by steel wire penetrating.
Described a kind of snake bone structure that can rotate freely is characterized in that: the hinged ear of described unidirectional pitch circle is corresponding with the installing hole of Serpentis joint bone A, B circle, and is connected by rivet is installed.
This utility model because of being separate articulated structure, can carry out the rotation of different directions by interconnecting that metal several unidirectional pitch circles and Serpentis joint bone A, B enclose, thereby realizes the crooked and swing of 360 degree.
The utility model has the advantages that:
This utility model is simple in structure, easy to install, realized the crooked and swing of 360 degree, and its price is low, and processing technique is simple, has improved productivity effect and economical and practical performance.
