Detailed Description

Example 1:

referring to fig. 1-4, an anti-rotation switch includes a cover 1, a base 2, and a button 3.

The cover plate 1 is made of a metal plate material, and in the embodiment, the cover plate 1 is preferably of a sheet structure, and the shape of the cover plate is consistent with that of the base 2, namely, the two fixed side walls are arranged in a coplanar manner. The central position of the cover plate 1 is provided with a first through hole 11 for the button 3 to pass through the first through hole 11 and extend out of the cover plate 1. The cover plate 1 is further provided with four riveting holes 12 distributed in an array mode, and the cover plate 1 and the base 2 achieve the effect of riveting and fixing through the riveting holes 12.

The base 2 is provided with a containing cavity 21, a first pin 4, a second pin 5 and a spring sheet 6.

The accommodating chamber 21 is only provided with an upper opening, and two sides of the accommodating chamber 21 are respectively provided with a limiting notch 211. The central position of the accommodating chamber 21 is preferably cylindrical, the limiting notches 211 are located on two sides of the cylindrical shape and are communicated with the central position, the cross section of each limiting notch 211 in the embodiment is preferably rectangular, the depth of each limiting notch 211 is consistent with that of the central position, and the size of each limiting notch 211 can be adjusted according to actual requirements. The two limit notches 211 are symmetrically arranged.

The first pins 4, the second pins 5 and the base 2 are integrally injection-molded, so that the first pins 4 partially extend into the accommodating cavity 21, the rest of the first pins extend out of the base 2, the second pins 5 also partially extend into the accommodating cavity 21, the rest of the second pins extend out of the base 2, and the parts of the first pins 4 and the second pins 5 extending out of the base 2 can be of a plug-in structure or a patch structure.

The first pin 4 is provided with two first connecting portions 41, the two first connecting portions 41 are both located in the accommodating chamber 21, and the two first connecting portions 41 are symmetrically arranged. Be equipped with first boss 42 on first connecting portion 41, first boss 42 includes first plane 421, first cambered surface 422 and second cambered surface 423, and first plane 421 is located first boss 42's top surface, and first cambered surface 422 one end is connected with first plane 421, and the other end extends downwards towards the outside, and second cambered surface 423 one end is close to center one side with first plane 421 and is connected, and the other end extends downwards towards center one side. Under the normal condition, the limit wall and the first plane 421 of shell fragment 6 offset to realize the normal fixed effect of shell fragment 6, shell fragment 6 is pressing the in-process, and deformation takes place for shell fragment 6, and the center of shell fragment 6 moves towards second connecting portion 51, and the limit wall of shell fragment 6 then slides on first cambered surface 422, and when applying the pressing force message on shell fragment 6, shell fragment 6 resumes deformation again, and this kind of structure setting, the motion of shell fragment 6 can not interfered to first boss 42.

The second pin 5 is provided with a second connection portion 51, and the second connection portion 51 is located between the two first connection portions 41, in this embodiment, the second connection portion 51 is preferably located at the center of the accommodating chamber 21. The second connecting portion 51 is provided with a second boss 52, and the second boss 52 is provided with a groove 521. The arrangement of the groove 521 forms a certain buffering effect, and prevents the elastic sheet 6 from completely adhering to the second boss 52. The recess 521 is preferably a cross recess here. The second boss 52 is located on the movement track of the elastic sheet 6, and in a normal state, the second boss 52 is not communicated with the elastic sheet 6.

The push button 3 is provided with a pressing portion 31, a fixing portion 32 and a driving column 33, the pressing portion 31 is located above the fixing portion 32 and connected to the fixing portion 32, the pressing portion 31 passes through the first through hole 11, so that the pressing portion 31 partially passes through the cover plate 1 and extends out of the cover plate 1. The fixing portion 32 reciprocates vertically up and down in the accommodating chamber 21, and is implemented by the elastic sheet 6. The two ends of the fixing portion 32 are provided with the limiting protrusions 321, so that the number of the limiting protrusions 321 is two, and the limiting protrusions 321 can vertically reciprocate in the limiting notches 211, in this embodiment, the limiting notches 211 limit the limiting protrusions 321 to rotate in the horizontal direction, that is, the side walls of the limiting notches 211 are located on the motion track of the limiting protrusions 321. Further, it should be noted here that, because the limiting protrusion 321 needs to perform vertical up-and-down reciprocating motion, a certain gap exists between the side wall of the limiting protrusion 321 and the limiting notch 211, and a slight rotation occurs in time during the pressing process, and when the limiting protrusion 321 abuts against the side wall of the limiting notch 211, the rotation effect cannot be achieved.

The driving column 33 is located below the fixing portion 32, one end of the driving column 33 is connected to the fixing portion 32, and the other end of the driving column 33 abuts against the spring 6. Through the setting of drive post 33, reduced the holistic raw and other materials of button 3, can realize the effect of drive shell fragment 6 through drive post 33. Meanwhile, in a normal state, the top surface of the fixing portion 32 is fixed against the bottom surface of the cover plate 1.

Further, in the present embodiment, the push button 3 is preferably formed by injection molding.

By adopting the structure, in the normal pressing use process, the button 3 is prevented from rotating due to the matching of the limiting protrusion 321 and the limiting notch 211, so that the sheath sleeved on the button can not rotate, and the direction of the sheath is ensured.
