Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electric actuator with an electric control component protection structure. Background Art

[0002] An electric actuator is an electric actuator mechanism, which is a driving device that can provide linear or rotational motion. It uses a certain driving energy source and works under a certain control signal. It is currently mainly used in switching valves to drive the valve to a fully open or fully closed position. It can also be called an electric valve.

[0003] Existing, the electric control component is generally fixedly connected to the electric actuator body by an external installation method, which makes the electric control component body, LCD screen, mode button and operation button easily damaged by external force, and then the electric control component cannot work normally to send control signals to the electric actuator; therefore, it is necessary to carry out corresponding protection for the electric control component, but most of the existing protection structures are fixed by bolts, and the installation process is complicated. When a failure or maintenance occurs, the bolts need to be removed one by one, and then installed one by one after maintenance, which takes a lot of installation time and has low practicality. At the same time, the bolts will rust and corrode after long-term use, and then disassembly and maintenance of the electric control component is cumbersome and very inconvenient to use. In view of this, we introduce an electric actuator with an electric control component protection structure. Utility Model Content
