[0002] The motor in the electric actuator is the core component for achieving energy conversion.

[0003] Common motor types include DC motors, AC motors, and stepper motors. These motors play a vital role in electric actuators, receiving electrical energy and converting it into mechanical energy to drive the actuator's movement. The motor's performance, efficiency, reliability, and precision significantly impact the overall performance of the electric actuator. Conventional electric actuators require the use of a wrench for manual and electric conversion, which is cumbersome and prone to damage. Therefore, an electric conversion structure for an electric actuator has been proposed to address these issues. Utility Model Content

A cylindrical through hole is formed within the housing, which is larger than the outer diameter of the connector. The cylindrical through hole extends through the end of the housing.

[0009] The limiting assembly includes a push rod and a limiting plate. Small through holes are opened at the top and bottom of the cylindrical through hole near the middle in the box body. Two push rods are provided, which are respectively engaged with the small through holes. Two limiting plates are provided. The two push rods are fixedly connected to the two limiting plates at one end facing the inside of the box body.

[0010] As an optimal technical solution of the present invention, a rotating rod is inserted into the cylindrical through hole, a clamping convex ring is fixedly connected to the outside of the rotating rod near the middle of the box body, and a sealing ring is fixedly connected to the outside of the rotating rod near the end of the box body.

[0011] As a preferred technical solution of the present invention, the snap-fitting protrusion is fitted with the limiting plate toward the connector side, and the horizontal width of the snap-fitting protrusion is equal to the distance between the end of the rotating rod and the internal groove of the connector.

[0012] As an optimal technical solution of the present invention, the rotating rod is located on the outside of the box and is fixedly connected to a rotating part at one end. The external bending parts of the rotating part are all designed as arcs, and occasional friction stripes are provided on the outside. The horizontal distance between the rotating part and the box is greater than the width of the clamping convex ring in the horizontal direction.

[0013] As a preferred technical solution of the present invention, the top of the push rod is fixedly connected to a pressing portion on the outside of the box after passing through the small through hole, and a spring is provided between the bottom of the pressing portion and the box and on the outside of the push rod.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides an electric conversion structure for an electric actuator, which has the following beneficial effects:

[0017] The electric conversion structure of the electric actuator can accurately limit and locate the position of the rotating rod through the design of the push rod and the limit plate. This structure helps to ensure the stability and accuracy of the manual operation of the electric actuator. When manual operation is required, it is only necessary to press the pressing part to drive the steel rope to move, and then drive the limit plate to move, thereby releasing the restriction on the clamping convex ring. The handheld rotating part pushes the rotating rod to plug into the connector. By designing the horizontal width of the clamping convex ring to be equal to the distance between the rotating rod and the connector groove, when the rotating rod is plugged into the connector, the pressing part is released, and the steel rope and the limit plate are driven to move back to their original position under the action of the spring. At this time, the limit plate can resist the other end of the clamping convex ring to prevent the rotating rod from moving in the horizontal direction when the handheld rotating part is rotated.
