Abstract
The invention relates to a rotating shaft structure with a stress absorbing performance. The rotating shaft structure is provided with a shaft lever and a shaft sleeve. A friction surface is formed on the edge of the shaft lever. A positioning surface is formed on one side of the friction surface. The shaft sleeve is provided with a base on one side of the shaft lever. The base faces is right opposite to the positioning surface. A resisting section, an elastic section and a pressing section extend from one end of the base. Notches are formed at the end of the pressing section and one end of the base far away from the resisting section, so as to enable the shaft sleeve cover the outer edge of the shaft lever. The base, the resisting section and the pressing section resist against the shaft lever and an elastic deformation space is formed between the elastic section and the friction surface. When the shaft lever rotates to enable the positioning surface and the base of the shaft sleeve to be in a non-positioned state, the shaft lever pushes the pressing section of the shaft sleeve to move, so as to enable the elastic section to move towards the shaft lever to absorb stress produced by the pressing section because of movement.

Embodiment
Refer to shown in Fig. 1 and 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 base portion 21 one end is extended with continuously against section 22, stretch section 23 and the section of compressing 24, and the section of compressing 24 end and base portion 21 are formed with short slot 25 away from the other end against section 22.
By upper, when the present invention is when organizing structure, axostylus axostyle 1 is arranged in beam barrel 2, beam barrel 2 is made to be coated on axostylus axostyle 1 outer rim, and allow the base portion 21 of beam barrel 2 be positioned at axostylus axostyle 1 lower side, and be right against the locating face 12 of axostylus axostyle 1, and the stretch section 23 of beam barrel 2 and the section of compressing 24 are for being positioned at the opposite side of axostylus axostyle 1 away from base portion 21, make stretch section 23 and the section of compressing 24 be positioned at axostylus axostyle 1 upper side; Moreover, the base portion 21 of beam barrel 2, against section 22 and the section of compressing 24 for being held in axostylus axostyle 1, and stretch section 23 is in arc-shaped, and the radian of stretch section 23 is less than rubbing surface 11 radian of axostylus axostyle 1, makes to be separated out a resiliently deformable space 3 between stretch section 23 and rubbing surface 11.
Refer to again shown in Fig. 1, when rotating shaft 10 is in closed state, the base portion 21 of its beam barrel 2 is right against the locating face 12 of axostylus axostyle 1, base portion 21 and locating face 12 is made to form positioning states, because the section of compressing 24 at the upper side of axostylus axostyle 1 can compress the rubbing surface 11 of axostylus axostyle 1, it is contrary with the turn direction (as shown in dotted line arrow in Fig. 1) of axostylus axostyle 1 that this compresses power, and a downforce can be produced to axostylus axostyle 1, therefore the anti-turn ability that axostylus axostyle 1 is larger can be bestowed, make axostylus axostyle 1 produce stable stationkeeping ability, be kept closed with stable allow axostylus axostyle 1 and beam barrel 2.
Refer to again shown in Fig. 2 and Fig. 3, find out by knowing in figure, when axostylus axostyle 1 is outwarded winding (turn direction as Fig. 2 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 can promote the section of compressing 24 of beam barrel 2, the section of compressing 24 is made to produce displacement towards the direction away from base portion 21, due to the flexible deformation space 3 of stretch section 23 and rubbing surface 11 interval of beam barrel 2, therefore, when axostylus axostyle 1 promotes the section of compressing 24 displacement, the stress that the section of compressing 24 produces because of displacement can be absorbed towards axostylus axostyle 1 displacement by stretch section 23, and because stretch section 23 is in arc-shaped, more can comparatively average for absorb stress be shared to whole stretch section 23, make the stress that stretch section 23 produces because of displacement with the resiliently deformable absorption section of compressing 24, fracture is caused to prevent stress from too concentrating a place.
Be with, the present invention is deficiency and the disappearance that can solve existing rotating shaft technology, its key technology is, utilize between the stretch section 23 of beam barrel 2 and the rubbing surface 11 of axostylus axostyle 1 and be separated out a resiliently deformable space 3, when making axostylus axostyle 1 and beam barrel 2 remove positioning states, the section of compressing 24 of beam barrel 2, because the stress produced, can be absorbed by stretch section 23 displacement and resiliently deformable, causes fracture to prevent stress from too concentrating a place.
