Detailed Embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment

[0024] Please refer to Figures 1 to 6 , which is an embodiment of the present utility model. This embodiment provides a technical solution: an anti-misoperation device for an electric actuator, including

[0025] a transparent cover 1 sleeved and installed on the surface of the electric actuator box 3, an operation notch 11 opened on the front surface of the transparent cover 1 and corresponding to the operation knob 31 in position, and a movable protection plate 2 slidably installed inside the transparent cover 1 and corresponding to the operation notch 11. Both the transparent cover 1 and the movable protection plate 2 are made of transparent acrylic material. Subsequently, the movable protection plate 2 can be slid down to block the operation notch 11, thereby effectively wrapping and protecting the operation knob 31, preventing non-professionals and irrelevant personnel from accidentally touching the operation knob 31, avoiding the problem of misoperation and malfunction, and ensuring the safety of the transparent cover 1;

[0026] and an upper limit structure and a lower limit structure.

[0027] Among them, slide rails 12 are adhesively fixed to the inner walls on both the left and right sides of the transparent cover 1, and the side of the movable protection plate 2 slides between the slide rails 12 and the inner wall of the transparent cover 1, enabling the movable protection plate 2 to slide up and down smoothly.

[0028] Among them, a strip 21 is adhesively fixed to the front surface of the bottom end of the movable protection plate 2, and the front end of the strip 21 extends out of the transparent cover 1 through the operation notch 11, facilitating subsequent operators to pinch the strip 21 to push the movable protection plate 2 up and down.

[0029] Among them, the upper limit structure includes an inner groove 51 opened inside the transparent cover 1, a spring 52 and a semi-circular telescopic latch 53 installed in the inner groove 51, and a limit card slot 54 opened on the top surface of the movable protection plate 2. The semi-circular telescopic latch 53 is movably installed in the inner groove 51 through the spring 52, and the end of the semi-circular telescopic latch 53 pops out into the limit card slot 54 to realize the clamping limit after the movable protection plate 2 slides upward, which is convenient for the operator to reach into the inner side of the transparent cover 1 through the operation notch 11 to perform corresponding adjustment operations on the operation knob 31. Subsequently, if the movable protection plate 2 needs to be slid downward, only need to pull down the movable protection plate 2 forcefully. When pulling down, the end of the semi-circular telescopic latch 53 will be squeezed and gradually pushed into the inner groove 51, and the movable protection plate 2 can be smoothly slid downward.

[0030] Among them, one end of the spring 52 is fixed to the inner wall of the inner groove 51, and the other end of the spring 52 is fixed to the semi-circular telescopic latch 53.

[0031] Among them, the lower limit structure includes a rubber bottom strip 22 adhesively fixed to the bottom surface of the movable protection plate 2, a rubber insertion strip 23 arranged on the bottom surface of the rubber bottom strip 22, and a strip-shaped slot 13 opened on the inner wall of the bottom end of the transparent cover 1 and corresponding to the rubber insertion strip 23. The rear surface of the rubber insertion strip 23 is provided with an integrated triangular latch 24. Both are made of rubber material and will undergo elastic deformation when squeezed. A side card slot 14 corresponding to the triangular latch 24 is opened on one inner wall of the strip-shaped slot 13. Subsequently, when the operator slides the movable protection plate 2 downward and closes the operation notch 11, the rubber insertion strip 23 will be inserted into the strip-shaped slot 13, and the triangular latch 24 will be squeezed into the side card slot 14, so as to realize the stable limit after the movable protection plate 2 slides downward. Subsequently, if the movable protection plate 2 needs to be slid upward again, only need to pinch the dial strip 21 and push the movable protection plate 2 upward forcefully. When pushing upward, the triangular latch 24 will be squeezed and elastically deformed and extruded from the side card slot 14, and the movable protection plate 2 can be smoothly slid upward.

[0032] Among them, bolt holes are opened on the top surface of the transparent cover 1, and the transparent cover 1 is fixed to the electric actuator box 3 by bolts.

[0033] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
