Abstract

Conventional rotary lock/release mechanisms typically take the form of friction discs or single-jaw designs, which suffer from several problems: large volume, difficult to install in many automated devices; the friction disc type mechanism can bear low torque and cannot be used under the working condition of large torque; the single-tooth-embedded mechanism has tooth clearance and return difference, and cannot be used in a scene needing high-precision positioning and locking. The main effect of this patent is fixed and guarantees not have gapped device, applies to the locking structure of two parallel surfaces that need angle of adjustment. Its advantages are high bearing torque, no return difference and high precision. The angle can be adjusted as desired.

Description

FIG. 2 is a schematic view of the structure of the present invention.

Detailed Description

The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

As shown in fig. 1, the locking device of the present invention includes an upper toothed disc 1, an outer ring toothed disc 2, a lower inner ring toothed disc 3, a fixed plate 4, a slewing bearing 5, and a fixed plate 6, wherein outer rings of the outer ring toothed disc 2, the fixed plate 4, and the slewing bearing 5 are fixed together by bolts, inner rings of the lower inner ring toothed disc 3, the fixed plate 6, and the slewing bearing 5 are fixed together by bolts, the fixed plate 4 and the fixed plate 6 are rotatable relative to each other, and the upper toothed disc 1 simultaneously fixes the outer ring toothed disc 2 and the lower inner ring toothed disc 3.

The upper fluted disc 1 is used for simultaneously fixing the outer ring fluted disc 2 and the lower inner ring fluted disc 3, so that the outer ring fluted disc 2 and the lower inner ring fluted disc 3 cannot rotate. Thereby achieving fixation between the fixed plate 4 and the fixed plate 6.

Conventional rotary lock/release mechanisms typically take the form of friction discs or single-jaw designs, which suffer from several problems: large volume, difficult to install in many automated devices; the friction disc type mechanism can bear low torque and cannot be used under the working condition of large torque; the single-tooth-embedded mechanism has tooth clearance and return difference, and cannot be used in a scene needing high-precision positioning and locking. This patent is used for fixing and guarantees not have gapped device, applies to the locking structure of two parallel surfaces that need angle of adjustment. Its advantages are high bearing torque, no return difference and high precision. The angle can be adjusted as desired.

The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the utility model. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
