Referring to fig. 1 to 6, fig. 1 is a partial sectional view of a preferred embodiment of a rotating shaft of the present invention, fig. 2 is a side sectional view of the preferred embodiment, fig. 3 is a perspective view of a rotating shaft rocker arm of the preferred embodiment, and fig. 4 to 6 are perspective views of different angles of the preferred embodiment; meanwhile, the moving direction of the corresponding part is indicated by a dotted arrow in fig. 1 and 2. The rotating shaft of the preferred embodiment mainly comprises a rotating shaft base body 1, a rotating shaft connecting rod 2, a rotating shaft rocker arm 3, a movable elastic arm 4, a limiting screw 5, a spring 6, a first connecting shaft 7 and a second connecting shaft 8. The rotating shaft base body 1 of the preferred embodiment can be detachably fixed on the frame of the machine needing the rotating shaft of the utility model, and the rotating shaft base body 1 can be designed to be integrally formed with the machine or the frame of the machine. The rotating shaft rocker arm 3 can be used for connecting parts needing to rotate on a machine; the swing arm 3 of the rotary shaft of the preferred embodiment can be detachably fixed to the part to be rotated on the machine to which the rotary shaft is to be applied, or can be integrally formed with the part to be rotated on the machine to which the rotary shaft is to be applied.

One end of the rotating shaft connecting rod 2 is pivoted between the two opposite side walls of the rotating shaft base body 1, and the other end is pivoted in the middle of the rotating shaft rocker arm 3. One end of the rotating shaft connecting rod 2 is movably connected with the rotating shaft base body 1 through a first connecting shaft 7, so that the rotating shaft connecting rod 2 can do rotating motion relative to the rotating shaft base body 1 by taking the first connecting shaft 7 as an axis. The middle part of the rotating shaft rocker arm 3 is movably connected with the other end of the rotating shaft connecting rod 2 through a second connecting shaft 8, so that the rotating shaft rocker arm 3 can do rotary motion relative to the rotating shaft connecting rod 2 by taking the second connecting shaft 8 as an axis. In the preferred embodiment, the first connecting shaft 7 and the second connecting shaft 8 are riveting shafts, that is, the two ends of the connecting shaft are fixed by riveting, so that the shafts can be prevented from sliding out, and the two parts connected by the riveting shafts can rotate relatively; other suitable pivoting structures may be used by those skilled in the art to design the first connecting shaft 7 and the second connecting shaft 8.

The movable elastic arm 4 is arranged between two opposite side walls of the rotating shaft base body 1, one end of the movable elastic arm 4 at the lower position is lapped at a preset circular arc fulcrum 9 on the rotating shaft base body 1, and therefore the other end of the movable elastic arm 4 can rotate relative to the rotating shaft base body 1 by taking the circular arc fulcrum 9 as an axis.

The spring 6 is installed between the other end of the movable elastic arm 4 at the high position and the rotating shaft base body 1, and the limiting screw 5 penetrates through the other end of the movable elastic arm 4 at the high position and is locked on the rotating shaft base body 1 together with the spring 6, so that the position of the spring 6 and the movable height of the movable elastic arm 4 are limited, and the spring 6 is in a prepressing state. The pre-pressing tension of the spring 6 causes the movable elastic arm 4 to generate certain elastic force.

The inner arc tracks 13 of the two opposite side walls of the rotating shaft base body 1 and the upper surface of the movable elastic arm 4 are combined to form the arc clamping groove 10, in the preferred embodiment, the arc tracks 13 on the side walls are the sliding tracks of the first mechanism 31 of the rotating shaft rocker arm 3, and determine the rotating arc path of the rotating shaft rocker arm 3.

The upper edge surfaces of two opposite side walls of the rotating shaft base body 1 form parallel and straight translation positions 11. The rotating shaft rocker arm 3 is provided with a first mechanism 31 corresponding to the arc clamping groove 10 and a second mechanism 32 corresponding to the translation position 11. During operation, the first mechanism 31 of the rotating shaft rocker arm 3 can slide along the arc clamping groove 10 formed by the rotating shaft base body 1 and the upper surface of the movable elastic arm 4 in an irregular arc manner, a certain damping force is formed at the contact point of the movable elastic arm 4 and the rotating shaft rocker arm 3, the damping force is the rotating torque force of the rotating shaft rocker arm 3, and meanwhile, the second mechanism 32 of the rotating shaft rocker arm 3 can slide horizontally along the translation position 11 of the rotating shaft base body 1. Therefore, the utility model realizes that the rotating shaft rocker arm 3 can rotate along an irregular radian and move horizontally at the same time, and forms the rotating shaft with a variable axis and an irregular radian rotating path.

In the preferred embodiment, the arc-shaped clamping groove 10 is specially provided with a limit clamping point structure to limit the rotation limit of a certain angle during the rotation of the rotating shaft rocker arm 3. In this embodiment, the arc line of the arc track 13 on the side wall at the position 12 is not consistent with the arc line at the corresponding position of the upper surface of the movable elastic arm 4 combined to form the arc clamping groove 10, so that the formed concave point structure is matched with the convex point 14 on the rotating shaft rocker arm 3 to form a limit clamping point of the rotating shaft rocker arm 3 at the angle, and the rotation angle of the limit rotating shaft rocker arm 3 can be adjusted and limited by selecting the position of the limit clamping point structure. If the rotation angle of the rotating shaft rocker arm 3 is not required to be limited, the upper arc line and the lower arc line of the arc clamping groove 10 can be designed to be consistent, namely, the arc line at the position 12 is consistent with the arc line at the corresponding position of the upper surface of the movable elastic arm 4. For the limit-stuck-point structure, a person skilled in the art may adopt other suitable structures instead of limiting the rotation angle of the rotating shaft rocker arm 3.

As described above, it will be apparent to those skilled in the art that various other changes and modifications can be made based on the technical solution and the technical idea of the present invention, and all such changes and modifications should fall within the protective scope of the appended claims.
