Abstract
The invention discloses a four-way snake bone and an assembling method thereof, 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 invention 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.

Described each middle joint is provided with two projections and two groove II.
Described projection and groove II interval are arranged, 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.
Position corresponding with face IA projection on described face IIB is groove I.
Described groove I is semi-circular recesses.
Described prosthomere and deutomerite are cylindrical structure.
The assemble method of four-way snake bone: comprise the following steps: 1, the projection of prosthomere is put in the groove II of first joint; 2, the projection of joint in first is put in the groove II of second joint; 3, repeat step 1 and step 2, the projection saved is put in the groove II of deutomerite in last, with tinsel successively through the pilot hole of prosthomere, middle joint, deutomerite.
Described tinsel has 4.
Adopt the structure of the present invention of technique scheme simple, be convenient to assembling, assemble effective, impact briquetting, avoid the yielding problem of expanding with heat and contract with cold adopting powder metallurgical technique to cause.
