Detailed Description

As shown in fig. 1-3, a dual-indication electric control box includes a box body 1, where the box body 1 at least includes an upper cover 2, a lower cover 3, an electric contact 4, and indication members 5 arranged in pairs, and the indication members 5 are push type structures, in this embodiment, control boxes of left and right direction keys. The upper cover 2 is internally provided with linkage pieces 6 fixedly connected with the electric contact pieces 4 and mounting grooves 7 for accommodating the linkage pieces 6, the linkage pieces 6 and the indicating pieces 5 are in one-to-one corresponding linkage assembly, and one linkage piece 6 corresponds to one indicating piece 5 and synchronously performs pressing action so as to trigger other mechanism reactions.

The linkage piece 6 is spacing face 8 towards 3 one end terminal surfaces of lower cover, and the linkage piece 6 has screens 9 on the 8 relative both sides of spacing face, be equipped with mounting hole 10 on screens 9, be equipped with spring and top pearl in the mounting hole 10, 7 inslots of mounting groove still are equipped with screens portion 11, be equipped with butt inclined plane 12 on screens portion 11, the top pearl passes through spring and 12 elasticity butts on the butt inclined plane, and linkage piece 6 keeps off through upper cover 2 and lower cover 3 and connects spacing restriction top pearl and break away from. The mounting hole 10 runs through the linkage 6, and both ends of the spring are provided with a top bead and a clamping part 11 which are in butt fit. The top beads are arranged in pairs and distributed on two sides of the spring, so that the top beads are axially propped against the abutting inclined surface 12 by elastic force, and the relative longitudinal movement of the linkage piece 6 is limited to a certain extent. Since the inclined abutting surface 12 is inclined, the spring is continuously stretched, and the top ball moves on the surface until the linkage piece 6 is stopped and limited, namely the linkage piece 6 reaches a specified position, the contacts of the electric contact pieces 4 are perfectly contacted, and the state is always kept to limit deviation, so that the stable and reliable use is ensured.

The butt inclined plane 12 is provided with a plurality of uniformly arranged fine teeth 13, which play a role similar to separation, and prevent the top bead from separating from the current position, so as to be beneficial to improving the stability of the top bead and the linkage piece 6.

The lower cover 3 is provided with a limiting seat 14, the limiting seat 14 is further provided with a through groove 15, a limiting part 16 connected in a hinged mode is arranged in the through groove 15, two ends of the limiting part 16 rotate relative to a hinged point of the through groove 15, and when the linkage part 6 is in butt joint linkage with one end of the limiting part 16, the other end of the other linkage part 6, which is inclined to the limiting part 16, is in butt joint limiting. The limiting member 16 can swing relatively, when one end falls, the other end tilts, so that the misoperation of simultaneously pressing the two indicating members 5 is limited, and only one of the two indicating members can be selected for operation.

The limiting member 16 is movably assembled with the groove wall of the through groove 15 through a connecting shaft 17, which is a common hinge mode and is not illustrated or limited herein. The limiting member 16 has a connecting portion 18 in the middle, the limiting member 16 has abutting portions 19 at two ends, the width of the limiting member 16 decreases from the connecting portion 18 to the abutting portions 19, and the abutting portions 19 are provided with protrusions 20 facing the linkage member 6. The relative area of the connecting part 18 is large, so that the structural strength of the connecting part is improved, and the protrusion 20 arranged on the abutting part 19 is beneficial to reducing loss, improving the response sensitivity and prolonging the service life. The linkage piece 6 is provided with a limit groove 21 for the limit piece 16 to extend into on the limit surface 8, so that the space occupation is reduced, and the layout is optimized.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, are not to be considered as limiting the present invention, and that the fundamental principles, the main features, and the advantages of the present invention are shown and described above, as would be understood by those skilled in the art.
