Technical Field

[0001] The utility model relates to the technical field of photoelectric turntables, in particular to a photoelectric turntable with mechanical limit buffering in a load compartment. Background Art

[0002] When designing the optoelectronic turntable, considering the safety of the equipment, it is often necessary to design three types of limiters: software limiter, electrical limiter and mechanical structure limiter. Mechanical structure limiter belongs to hard limiter, which is usually realized by contacting the limit pin installed on the rotating body with the limit groove boundary on the fixed base. During the rotation of the conventional rotating body, the limit pin moves inside the limit groove. The structure is as shown in the Chinese utility model patent (authorization announcement number: CN207490086U Name: A manual two-dimensional turntable for antenna) includes a pitch adjustment component and an azimuth adjustment component: the pitch adjustment component includes a left bracket and a left arm on the left side of the flat antenna and a right bracket and a right arm on the right side of the flat antenna. The left and right brackets are fixed to the flat antenna. The left arm is provided with a left shaft sleeve that rotates with the left bracket, and the right arm is provided with a right shaft sleeve that rotates with the right bracket. A damping disk is fixed to the right bracket, and a first locking screw that is threadedly installed on the right arm to lock with the damping disk. The left and right arms are vertically fixed above the horizontal flange plate; the azimuth adjustment component includes a base and a rotating shaft located below the flange plate and vertically fixed to the flange plate. The rotating shaft is installed on the base through a bearing seat, a bearing cover and a self-aligning bearing. A second locking screw that is threadedly installed on the flange plate to lock with the bearing seat. The utility model has a simple structure, is easy to adjust and lock the antenna angle, and is convenient to install and adjust. However, when the turntable loses control during operation, the first locking screw hits the damping disk. Due to the excessive impact force, the first locking screw may be bent or even broken, causing the turntable to lock and resulting in equipment failure. Utility Model Content
