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
See also Fig. 1 and shown in Figure 2, find out that by knowing among the 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 circular-arc rubbing surface 11, and rubbing surface 11 1 sides are formed with plane locating face 12, and the axle center 13 of axostylus axostyle 1 is 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 1 ends are extended with against section 22, stretch section 23 and the section of compressing 24 continuously, and the section of compressing 24 ends are formed with short slot 25 with base portion 21 away from the other end against section 22.
By last; When the present invention, is arranged in axostylus axostyle 1 in the beam barrel 2 during structure in group, make beam barrel 2 be coated on axostylus axostyle 1 outer rim; And let 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 make stretch section 23 and the section of compressing 24 be positioned at axostylus axostyle 1 upper side for to be positioned at the opposite side of axostylus axostyle 1 away from base portion 21; 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 circular-arc, and the radian of stretch section 23 makes 11 of stretch section 23 and rubbing surfaces be separated out a resiliently deformable space 3 less than rubbing surface 11 radians of axostylus axostyle 1.
See also shown in Figure 1 again; When rotating shaft 10 during in closed state, the base portion 21 of its beam barrel 2 is right against the locating face 12 of axostylus axostyle 1, makes base portion 21 and locating face 12 form positioning states; Because the section of compressing 24 of axostylus axostyle 1 top one side can compress the rubbing surface 11 of axostylus axostyle 1; This turn direction (shown in dotted line arrow among Fig. 1) that compresses power and axostylus axostyle 1 is opposite, and can produce a downforce to axostylus axostyle 1, therefore can bestow the bigger anti-turn ability of axostylus axostyle 1; Make axostylus axostyle 1 produce stable stationkeeping ability, be kept closed with stable let axostylus axostyle 1 and beam barrel 2.
See also Fig. 2 and shown in Figure 3 again, find out by knowing among the figure, when axostylus axostyle 1 is outwarded winding (the turn direction is shown in solid arrow among Fig. 2); The rotation of axostylus axostyle 1 can make the locating face 12 and the base portion 21 of beam barrel 2 break away from positioning states, because the radius that rubbing surface 11 is arrived in the axle center 13 of axostylus axostyle 1 is greater than the radius of axle center 13 to locating face 12, therefore; When locating face 12 broke away from positioning states with base portion 21, axostylus axostyle 1 can promote the section of compressing 24 of beam barrel 2, made the section of compressing 24 produce displacement towards the direction away from base portion 21; Because the stretch section 23 of beam barrel 2 and the flexible deformation space 3 in rubbing surface 11 intervals; Therefore, when axostylus axostyle 1 promoted the section of compressing 24 displacements, the section of compressing 24 can be absorbed towards axostylus axostyle 1 displacement by stretch section 23 because of the stress that displacement produced; And because stretch section 23 is circular-arc; More can make stretch section 23 absorb the section of compressing 24 because of the stress that displacement was produced comparatively average the sharing of the stress that is absorbed, cause fracture to prevent stress from too concentrating a place to whole stretch section 23 with resiliently deformable.
Be with; The present invention is for solving the deficiency and the disappearance of existing rotating shaft technology, and its key technology is, utilizes the stretch section 23 of beam barrel 2 and 11 of the rubbing surfaces of axostylus axostyle 1 to be separated out a resiliently deformable space 3; When making axostylus axostyle 1 remove positioning states with beam barrel 2; The section of compressing 24 of beam barrel 2 causes fracture because the stress that produced can be absorbed by stretch section 23 displacements and resiliently deformable to prevent the too concentrated place of stress.
