Detailed Description
This section is an embodiment of the present invention for explaining and explaining the technical solution of the present invention.
A microswitch guide structure comprises a microswitch and a guide rod; the microswitch comprises a switch, a sheet body and a roller, wherein one end of the sheet body is connected with the roller, and the other end of the sheet body is contacted with the switch; the guide rod is a cylindrical rod body capable of moving axially, and is in line contact with a roller of the microswitch; the guide rods have different diameters in the axial direction.
The axial direction of the guide rod is provided with two diameters, one diameter is a guide large diameter 1, the other diameter is a guide small diameter 3, and the radius difference between the guide large diameter 1 and the guide small diameter 3 is equal to the overtravel of the microswitch. The guide rod has guide large diameter 1 and guide small diameter 3, and the guide rod is over the guide conic surface 2, and the guide conic surface 2 has angle in the range of 20-25 deg. The microswitch is arranged above the guide rod.
For better explanation of the present invention, the following detailed description is provided with reference to the accompanying drawings.
Please refer to fig. 1-2, which are schematic structural diagrams and structural embodiments of the present invention.
Initially, the micro switch 5 and the guide mechanism are both arranged on the mounting body 4, the contact of the micro switch 5 is contacted with the guide small diameter 3, and the micro switch 5 is positioned in a pre-stroke section and outputs an electric signal; when the mechanism moves, the contact of the micro switch 5 slides through the guide conical surface 2 to be contacted with the guide large diameter 1, the contact of the micro switch 5 is compressed, the micro switch 5 is positioned in an overtravel section, and another electric signal is output.
