Abstract
The invention discloses a rotation shaft structure with an elastic deformation space. The rotation shaft structure with the elastic deformation space is provided with a shaft rod and a shaft cylinder. The periphery of the shaft rod forms a friction surface. A side of the friction surface forms a positioning surface. A shaft cylinder side located at the shaft rod is provided with a base. The base is arranged over against the positioning surface and the base and the positioning surface are in a positioning state. One base end bends and extends to form a first elastic section and a pressing section. A tail end of the pressing section and the other base end far away from the first elastic section form a groove. The shaft cylinder coats the periphery of the shaft rod. The base and the pressing section press against the shaft rod. An elastic deformation space is formed between the first elastic section and the friction surface. When the shaft rod rotates so that the positioning surface and the base of the shaft cylinder are not in a positioning state, the shaft rod pushes the pressing section of the shaft cylinder to move. The elastic deformation space is formed between the first elastic section and the friction surface and thus the first elastic section can move towards the shaft rod to absorb the stress produced by pressing section displacement.

Embodiment
Refer to shown in Fig. 1 and shown in Fig. 2, find out by knowing in figure, rotating shaft 10 of the present invention is provided with axostylus axostyle 1 and beam barrel 2, wherein:
This axostylus axostyle 1 outer rim is formed with the rubbing surface 11 of arc-shaped, and rubbing surface 11 side is formed with plane locating face 12, and the axle center 13 of axostylus axostyle 1 is be greater than the radius of axle center 13 to locating face 12 to the radius of rubbing surface 11.
This beam barrel 2 is provided with flat base portion 21, and the bending of base portion 21 one end is extended with the first stretch section 22 and the section of compressing 23, and the section of compressing 23 end and base portion 21 are formed with short slot 24 away from the another end of the first stretch section 22.
By upper, when the present invention is in time organizing structure, axostylus axostyle 1 is arranged in beam barrel 2, make beam barrel 2 for being coated on axostylus axostyle 1 outer rim, and allow the base portion 21 of beam barrel 2 for being positioned at axostylus axostyle 1 lower side, and be right against the locating face 12 of axostylus axostyle 1, and the section of compressing 23 of beam barrel 2 is for being positioned at the another side of axostylus axostyle 1 away from base portion 21; Moreover the section of compressing 23 of beam barrel 2 is for being held in axostylus axostyle 1, and the first stretch section 22 is in arc-shaped, and the radian of the first stretch section 22 is rubbing surface 11 radian being less than axostylus axostyle 1, is separated out resiliently deformable space 3 in order to do making between the first stretch section 22 and rubbing surface 11.
When axostylus axostyle 1 is outwarded winding (turn direction as Fig. 2 figure in solid arrow shown in), the rotation of axostylus axostyle 1 can make locating face 12 depart from positioning states with the base portion 21 of beam barrel 2, because the axle center 13 of axostylus axostyle 1 is be greater than the radius of axle center 13 to locating face 12 to the radius of rubbing surface 11, therefore, when locating face 12 departs from positioning states with base portion 21, axostylus axostyle 1 is the section of compressing 23 that can promote beam barrel 2, the section of compressing 23 is made to produce displacement towards the direction away from base portion 21, due to the flexible deformation space 3 of the first stretch section 22 and rubbing surface 11 interval of beam barrel 2, therefore, when axostylus axostyle 1 promotes the section of compressing 23 displacement, the stress that the section of compressing 23 produces because of displacement can be absorbed towards axostylus axostyle 1 displacement by the first stretch section 22, and because the first stretch section 22 is in arc-shaped, more can comparatively average for absorb stress be shared to whole first stretch section 22, make the stress that the first stretch section 22 produces because of displacement with the resiliently deformable absorption section of compressing 23, fracture is caused to prevent stress from too concentrating a place.
Refer to shown in Fig. 3 and Fig. 4, find out by knowing in figure, rotating shaft 10 of the present invention is provided with axostylus axostyle 4 and beam barrel 5, wherein:
This axostylus axostyle 4 outer rim is formed with the rubbing surface 41 of arc-shaped, and rubbing surface 41 side is formed with plane locating face 42, and the axle center 43 of axostylus axostyle 4 is be greater than the radius of axle center 43 to locating face 42 to the radius of rubbing surface 41.
This beam barrel 5 is provided with flat base portion 51, and base portion 51 one end bends continuously and is extended with the first stretch section 52, against section 53, second stretch section 54 and the section of compressing 55, and the section of compressing 55 end and base portion 51 form short slot 56 away from the another end of the first stretch section 52.
By upper, when the present invention is in time organizing structure, axostylus axostyle 4 is arranged in beam barrel 5, make beam barrel 5 for being coated on axostylus axostyle 4 outer rim, allow the base portion 51 of beam barrel 5 and the first stretch section 52 for being positioned at axostylus axostyle 4 lower side, and base portion 51 is right against the locating face 42 of axostylus axostyle 4, and the second stretch section 54 of beam barrel 5 and the section of compressing 55 are for being positioned at the another side of axostylus axostyle 4 away from base portion 51 and the first stretch section 52, make the second stretch section 54 and the section of compressing 55 be positioned at axostylus axostyle 4 upper side; Moreover, the base portion 51 of beam barrel 5, against section 53 and the section of compressing 55 for being held in axostylus axostyle 4, and the first stretch section 52 and the second stretch section 54 are in arc-shaped, and the radian of the first stretch section 52 and the second stretch section 54 is rubbing surface 41 radian being less than axostylus axostyle 4, in order to do making the first stretch section 52 and the second stretch section 54 respectively and be separated out the first resiliently deformable space 6 and the second resiliently deformable space 7 between rubbing surface 41.
When axostylus axostyle 4 is outwarded winding (turn direction as Fig. 4 figure in solid arrow shown in), the rotation of axostylus axostyle 4 can make locating face 42 depart from positioning states with the base portion 51 of beam barrel 5, because the axle center 43 of axostylus axostyle 4 is be greater than the radius of axle center 43 to locating face 42 to the radius of rubbing surface 41, therefore, when locating face 42 departs from positioning states with base portion 51, axostylus axostyle 4 is the section of compressing 55 that can promote beam barrel 5, make the section of compressing 55 produce displacement towards the direction away from base portion 51, and the stress that the section of compressing 55 produces because of displacement can first be absorbed towards axostylus axostyle 4 displacement by the second stretch section 54; Moreover, the resist force that the section of compressing 55 produces when displacement can act on axostylus axostyle 4, axostylus axostyle 4 is pushed towards against section 53, and the second stretch section 54 is in also acting on against section 53 towards the stress produced during axostylus axostyle 4 displacement, make slightly to produce skew against section 53, and then allow the first stretch section 52 absorb against section 53 because offseting the stress produced towards axostylus axostyle 4 displacement; Again, this first stretch section 52 and the second stretch section 54 are in arc-shaped, therefore, and can by comparatively average the sharing of absorbed stress, make the first stretch section 52 and the second stretch section 54 absorb the stress because displacement produces with resiliently deformable, cause fracture to prevent stress from too concentrating.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many amendments, change or equivalence, but they all will fall within the scope of protection of the present invention in the spirit and scope of claim restriction to it.
