Description

Damping locking structure Technical Field The utility model relates to the technical field of stage lamps, in particular to a damping locking structure. Background In the technical field of stage lamps, many connection structures require rotation and specific resistance, and a common method for realizing the rotation structure with resistance is realized by a screw locking mode. If the screw is adopted, the single screw plays the role of a bearing shaft and provides axial locking force for the contact surface, but when the rotating direction of the rotating arm is opposite to the locking direction of the locking screw, the screw is reversely driven to reversely rotate so as to loosen the screw, the axial locking force is not provided, and the structure is invalid. For example, the screw is realized by a plurality of screws (two screws or more), and the problem of single screw can be solved, but the structure is complex, the miniaturization is difficult, and the screw cannot be used particularly when the structure is compact. Disclosure of utility model In view of the above, the present utility model provides a damping locking structure, which mainly solves the problems in the background art. The utility model provides a damping locking structure which comprises a knob, a fixed seat, a damping sheet, a rotating seat and a connecting piece, wherein the connecting piece is respectively matched with the rotating seat, the damping sheet, the fixed seat and the knob, the connecting piece comprises a limiting section, a rotating section, a square shaft section and a screw section which are of an integrated structure, the sectional area of the limiting section is larger than that of a through hole of the rotating seat, the rotating section is positioned in the through hole of the rotating seat, the rotating section or the square shaft section is positioned in a through hole of the damping sheet, the square shaft section is also positioned in a square hole of the fixed seat, the fixed seat also comprises a round hole communicated with the square hole, the screw section is in threaded fit with the knob after penetrating through the round hole, one side of the rotating seat facing the damping sheet is provided with a first tooth surface, and one side of the fixed seat facing the damping sheet is provided with a second tooth surface. The rotary seat is characterized in that the first spline surface comprises a plurality of first tooth sections, the plurality of first tooth sections are distributed from the edge close to the through hole to the periphery of the rotary seat, the second spline surface comprises a plurality of second tooth sections, and the plurality of second tooth sections are distributed from the edge close to the square hole to the periphery of the fixed seat. The further improvement is that the section shape of the tooth segment is trapezoid. The knob is further improved in that the periphery of the side wall of the knob is provided with patterns, and the patterns are bar-shaped or arc-shaped. The further improvement is that the fixing seat is arranged on one side of the fixing arm and is of an integrated structure. The further improvement is that the rotating seat is arranged at one side of the rotating arm and is of an integrated structure. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the first spline surface of the rotary seat is extruded to the damping fin by pulling the knob, the damping fin is extruded to the second spline surface of the fixed seat, then the damping fin generates friction force with the first spline surface and the second spline surface respectively, the knob is screwed with the thread section, and the loosening of the rotary seat in the opposite screwing direction relative to the knob and the thread section is reduced by utilizing the cooperation of the square shaft section and the square shaft hole, so that the rotary seat is simple in structure and can be applied to stage lamps with compact structures.
