Description

Technical Field

[0001] The utility model belongs to the technical field of micro switch control devices, and in particular relates to a micro switch control device. Background Art

[0002] A micro switch is a switch with a tiny contact interval and a snap-action mechanism, a contact mechanism that performs a switching action with a specified stroke and a specified force, covered with a shell, and having a driving rod on the outside. Currently, the commonly used micro switch control device uses a method of vertically pressing the active contact of the micro switch to trigger the micro switch to switch the circuit state.

[0003] The "micro switch operating device" with patent number "CN201821937164.7" disclosed on May 7, 2019, includes a bracket and a swing plate, a micro switch is fixed at the left end of the bracket, a rotatable lever is arranged at the lower part of the micro switch, and a roller is installed at the end of the lever; the swing plate is composed of a pressure plate and a rotating plate, the pressure plate and the rotating plate are arranged at an angle of 130°-170°, the swing plate and the bracket are supported by a compression spring, the top of the compression spring is positioned at the connection between the pressure plate and the rotating plate by a first screw, and the bottom of the compression spring is positioned at the bottom end of the bracket by a second screw; the rotating plate extends to the bottom of the roller, the rotating plate is hinged to the bracket through a core shaft, and a limit screw is threadedly connected to the rotating plate, and the limit screw is used to adjust the starting angle of the micro switch on and off;

[0004] In the above technical solution, the pendulum plate is installed on the bracket through the core shaft. When the right end of the pendulum plate is pressed by hand, the left end of the pendulum plate rises and pushes the roller on the switch to rotate upward. The upward rotating roller presses the micro switch so that its two contacts are in contact, and the circuit is connected. The whole operation is simple and labor-saving, and the initial angle of the pendulum plate can be adjusted by the positioning nut to meet the needs of different micro switches.

[0005] However, the above-mentioned operating device still has defects. For example, the operating force required for opening and closing the micro switch is relatively large, and there is no angle limit when the rotating plate rotates. If the rotating plate rotates too much, the micro switch will be damaged. Utility Model Content

[0006] In order to overcome the deficiencies in the prior art, the utility model provides a control device for a micro switch which is simple to operate, labor-saving and has low loss.

[0013] It is further configured as follows: a limiting groove is provided on one end of the fixing plate facing the coupling plate, and a limiting column is fixedly connected to one end of the coupling plate facing the limiting groove.

[0014] It is further configured as follows: one end of the limiting column extends into the limiting groove, thereby limiting the coupling plate.

[0015] It is further configured as follows: the handle is in a semicircular arc shape.

[0016] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to operate; the overlap shaft is rotatably connected to the box body and the fixed plate through the first bearing and the second bearing, so that the overlap shaft is rotated to drive the coupling plate to rotate to open and close the micro switch; springs are installed on the first hanging spring pin and the second hanging spring pin, and the elastic force of the spring facilitates the rotation of the coupling plate, which saves effort when the micro switch is opened and closed; the coupling plate is limited by the limit groove and the limit column to prevent the coupling plate from damaging the micro switch due to the large rotation angle, and at the same time, the elastic force of the spring cooperates with the limit groove and the limit column to limit the coupling plate, which can prevent the coupling plate from accidentally touching the micro switch.
