The invention discloses an annular rotating device, including a fixing frame, a rotating annular body, a first and second lamp arm connecting parts and rotating torsion assemblies. The fixing frame comprises a fixing annular body and a flange annular, and the rotating torsion assemblies comprise shaft centers, upper and lower friction pieces, support columns, a plurality of disc shaped spring pieces and lock nuts, by arranging arc-shaped slide rails on a rotating annular body, the arc-shaped slide rails are used for guiding the shaft centers, then the shaft centers are fixed on the fixing annular body, the relative rotation function between the rotating annular body and the fixing annular body is realized, through the lock nuts, the disc shaped spring pieces and the friction pieces are locked on the top face of the rotating annular body, the upper and lower friction pieces are in contact with the rotating annular body in a friction mode, and rotating torsion between the rotating annular body and the fixing annular body is provided. According to the annular rotating device, the annular space structure is provided, an annular lamp can be supported, the rotating torsion can be adjusted in real time, reliability is ensured, and at the same time, a hand feeling of a user is taken into account.
Description
technical field [0001] The invention relates to a rotating device, in particular to an annular rotating device used for products such as desk lamp brackets that require relative rotation. Background technique [0002] Desk lamp is a kind of lighting appliance commonly used in daily life, mainly placed on desk, desk. Desk lamps usually include a base, a bracket and a lamp holder. One end of the bracket is installed on the base, and the other end of the bracket is connected with the lamp holder. The range is relatively small and focused, and can only provide illumination for a small area. For this reason, desk lamp needs to have rotating joint, and like this, support usually comprises upper support and lower support, and lower support is installed on the base, and upper support is installed on the lamp cap, is connected by rotating device between upper support and lower support, to realize upper support. The rotation function of the bracket relative to the lower bracket can ...
