Abstract

The invention relates to a rotation shaft structure, which comprises a first body, a second body, a central shaft and an adjustment unit, wherein the first body comprises a first connection part, thesecond body comprises a second connection part, the central shaft is rotatably arranged on the first connection part and the second connection part, the adjustment unit is arranged on the central shaft and comprises an adjustment ring and a first gasket, the adjustment ring is sleeved on the central shaft, and the first gasket is sleeved on the central shaft and applies force on the second body orthe first body, such that the action force on the second body or the first body by the first gasket can be adjusted by adjusting the axial position of the adjustment ring on the central shaft so as to adjust the second body or the first body to achieve the rotatable or fixed state relative to the central shaft.

Description

technical field [0001] The present invention relates to a rotating shaft structure, in particular to a rotating shaft structure capable of setting a fixed rotating torque. Background technique [0002] Generally, a device with a rotating shaft structure (such as binoculars or binocular rangefinder, etc.) can be used as the center of rotation to operate the left (or right) lens barrel to rotate relative to the right (or left) lens barrel to adjust The distance between the eyes, however, the general device with the structure of the rotating shaft lacks the function of adjusting the torque value of the device during rotation, which causes inconvenience to the user in operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotating shaft structure to increase or decrease the torque value in the structure by pressing or loosening the adjustment ring in view of the defect that the torque value of the device in the...
