Abstract
The utility model discloses a four-way snake bone with a camera tube, and particularly relates to a four-way snake bone and an assembling method thereof, wherein the four-way snake bone is capable of rotating freely and is provided with a camera tube. The utility model aims to solve the technical problem in the prior art that, existing snake bones are complex in structure, difficult to assemble, poor in assembling effect, high in price, complicated in machining process, large in size and inflexible to use. The four-way snake bone comprises a front section and a rear section. At least one middle section is arranged between the front section and the rear section. The middle section is composed of a surface IA and a surface IIB. The surface IA is provided with a bump, and the surface IIB is provided with a groove II. The front end of the front section is provided with a camera tube, and the rear end of the front section is provided with a bump matched with the groove II of the surface IB. The rear section is provided with a groove II matched with the bump of the surface IA. The bump and the groove II are respectively provided with a positioning hole. Due to the adoption of the structure, the four-way snake bone is convenient to assemble and good in assembling effect and is manufactured through the punching molding process. Meanwhile, the problems of thermal expansion/contraction and easy deformation during the powder metallurgy process are solved.
Description
Technical field
The utility model relates to a kind of snake bone, be specifically related to a kind of can rotate freely and with camera pipe four-way snake bone.
Background technology
Existing endoscope will be realized head-bent break-in, all adopt a built-in strip metal snake bone joint, the method of the control wire being attached thereto by tractive makes its bending, and this strip metal snake bone is to save coupling shaft by the pass of each joint to interconnect, axial rotation is carried out work again, equidirectional axle can only have the bending of forward and reverse direction, want the multi-direction coupling shaft that must make certain several joint to be on different positions, although existing metal snake-bone also can be accomplished the omnidirectional bending of 360 degree and swing, but its complex structure, assembling difficulty, assembling weak effect, and its price is high, processing technology complexity, adopt powder metallurgical technique, flexible type, productivity effect and economical and practical performance are affected, and when being connected with camera, camera need to be put in camera pipe in snake bone, volume is large, use dumb.
Utility model content
The technical problems to be solved in the utility model is existing metal snake-bone complex structure, assembling difficulty, and assembling weak effect, price is high, processing technology complexity, volume is large, uses dumb, provide a kind of simple in structure, assemble effective, the directly four-way snake bone with camera pipe of built-in camera.
For achieving the above object, the utility model adopts following technical proposals: a kind of four-way snake bone with camera pipe, comprises prosthomere and deutomerite, between prosthomere and deutomerite, be provided with at least one middle joint, described middle joint comprises face IA and face IIB, and face IA is provided with projection, and face IIB is provided with groove II; The front end of described prosthomere is provided with camera pipe, and rear end is provided with the projection matching with face IIB groove II, and deutomerite is provided with the groove II matching with face IA projection; On described projection and groove II, be equipped with pilot hole.
The radius of described camera pipe is greater than the radius of prosthomere.
Described each middle joint is provided with two projections and two groove II.
Described projection and groove II interval arrange, and two protruding connecting lines are vertical with the connecting line of two groove II.
Described projection is semi-cylindrical hill, and described groove II is semi-circular recesses.
The upper position corresponding with face IA projection of described face IIB is groove I.
Described groove I is semi-circular recesses.
Described prosthomere and deutomerite are cylindrical structure.
Adopt the utility model of technique scheme simple in structure, be convenient to assembling, assemble effectively, impact briquetting, avoids the yielding problem of expanding with heat and contract with cold that adopts powder metallurgical technique to cause.

Embodiment
As shown in Figures 1 to 8, a kind of four-way snake bone, comprises prosthomere 1 and deutomerite 2, is provided with at least one middle joint 3 between prosthomere 1 and deutomerite 2, and described middle joint 3 comprises face IA and face IIB, and face IA is provided with projection 4, and face IIB is provided with groove II6; The front end of described prosthomere 1 is provided with camera pipe 11, and rear end is provided with the projection 4 matching with face IIB groove II6, and deutomerite 2 is provided with the groove II6 matching with face IA projection 4; On described projection 4 and groove II6, be equipped with pilot hole 7.
The radius of described camera pipe 11 is greater than the radius of prosthomere 1.Camera pipe 11 is as a part for prosthomere, and camera can be directly installed in camera pipe, makes the smaller volume after camera and snake bone are installed, and length shortens, and uses more flexible.
Described each middle joint 3 is provided with two projections 4 and two groove II6.
Described projection 4 and groove II6 interval arrange, and the connecting line of two projections 4 is vertical with the connecting line of two groove II6.
Described projection 4 is semi-cylindrical hill, and described groove II6 is semi-circular recesses.Semicircular protruding 4 and semicircular groove II6 the two is smoothly joined, movable flexibly.
The upper position corresponding with face IA projection 4 of described face IIB is groove I5.
Described groove I5 is semi-circular recesses.
Described prosthomere 1 and deutomerite 2 are cylindrical structure.
The assemble method of four-way snake bone: comprise the following steps: 1, the projection of prosthomere 14 is put into first and saved in 3 groove II6; 2, the projection 4 that saves 2 in first being put into second saves in 3 groove II6; 3, repeating step 1 and step 2, puts into the projection saving in last 4 in the groove II6 of deutomerite 2, passes successively the pilot hole 7 of prosthomere 1, middle joint 3, deutomerite 2 with tinsel.Described tinsel has 4.Under the pulling of four one metal wires, drive the gib head of snake bone to rotate.
