Embodiment Construction
[0013] An electric actuator box that prevents paint from falling off, including a box body 1, a number of screw countersunk holes 2 are arranged around the connection of the lower end of the box body 1, and the step surface of the screw counterbore 2 is Several protrusions 3 are provided, and the plurality of protrusions 3 are evenly distributed around the counterbore hole 2 of the screw.
[0014] Further, the shape of the protrusions 3 is semi-spherical, and the number of the protrusions 3 is 6-12.
[0015] Further, a drainage groove 4 is provided on the side wall of the screw counterbore 2, and the opening direction of the drainage groove 4 faces outward.

The invention relates to an electric actuator casing preventing paint from falling. The electric actuator casing comprises a casing body, a connection position of the lower end of the casing body is circumferentially provided with a plurality of screw counter sinks, the step surfaces of the screw counter sinks are provided with a plurality of projections, and the plurality of projections are uniformly distributed around the screw counter sinks. The structure is simple, through additional arrangement of the plurality of projections on the step surfaces of the screw counter sinks in the casing, the contact area between screws and the casing is reduced, additional arrangement of elastic pads during assembling is unnecessary, and the projections can realize an anti-loosening effect. When the screws need to be dismounted after the paint is sprayed to the surface of the casing, since the screws are not completely in contact with the casing, the screws do not drive surrounding paint, the possibility of paint falling is reduced, and the overall appearance effect is guaranteed.
Description
technical field [0001] The invention relates to a paint-off-proof electric actuator box. Background technique [0002] At present, many devices have strict requirements on appearance. Due to the advantages of high connection strength and bright color of stainless steel screws, many devices are connected by stainless steel screws. After the processing is completed, the equipment needs to be painted after assembly. During the painting process, the screws will also be sprayed with paint. When the maintenance needs to be disassembled, when the stainless steel screws are unscrewed, a small area of paint around the stainless steel screws will be driven. peeling off, which affects the appearance of the entire device. Contents of the invention [0003] In view of the above-mentioned defects, the purpose of the present invention is to provide a simple structure, reduce the possibility of paint peeling off when the screw is disassembled, and ensure the overall appearance of an e...
