Synchronous homologous primary frequency modulation accurate control device

Abstract

The utility model discloses a synchronous homologous primary frequency modulation accurate control device, which belongs to the technical field of primary frequency modulators, and comprises a primary frequency modulator main body, a control panel is arranged on the side surface of the primary frequency modulator main body, and two protective covers are movably arranged on the side surface of the primary frequency modulator main body at positions opposite to the control panel. The two protective covers are used in cooperation, a plate frame is fixedly installed on the side face of one protective cover, a clamping hole is formed in the side face of the plate frame, and an insertion plate is fixedly installed on the side face of the other protective cover and inserted into the plate frame. By arranging the two protective covers, the control panel can be isolated and protected when the control panel is not used, the two protective covers are locked after being closed through the plate frame, the inserting plate and the clamping plate, the protective effect is good, the protective covers can be driven to be rapidly opened through the elastic force of the first spring after the two protective covers are unlocked, operation is convenient, the structure is simple, and practicability is high. And the problem that the control panel is damaged due to mistaken touch when the control panel is not used can be effectively avoided.
