Abstract
The utility model discloses a four-way snake bone, 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. The utility model aims to solve the technical problem in the prior art that, existing metallic snake bones are complex in structure, difficult to assemble, poor in assembling effect, high in price and complicated in machining process. 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 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 4 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, is specifically related to a kind of four-way snake bone that can rotate freely.
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.
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, and processing technology complexity provides a kind of simple in structure, assembles effective four-way snake bone.
For achieving the above object, the utility model adopts following technical proposals: a kind of four-way snake bone, 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; Described prosthomere 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 4 and groove II, be equipped with pilot hole.
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.
