Description

Technical Field

[0001] The utility model relates to the technical field of travel switches, and particularly relates to a travel switch ejector rod structure. Background Technique

[0002] A travel switch, a kind of position switch (also known as a limit switch), is a commonly used small-current master electrical appliance. A micro switch element similar to a button is contained in various travel switches. When in use, when the travel of the working machine reaches a certain specified distance, the striker of the travel switch is pressed down, the micro switch is pressed, and its contacts will perform opening (or closing) actions.

[0003] When the forming switch is in use, it needs to trigger the switch action through the ejector rod. However, the common ejector rod generally cannot adjust the angle, resulting in the inability to adjust the trigger point after the position of the entire forming switch is safely completed, and there are certain limitations in use. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a travel switch ejector rod structure, which solves the problems mentioned in the above background.

[0006] It is characterized in that it further includes:

[0007] A connecting support plate, fixedly arranged on the outer wall of the switch connecting shaft;

[0008] A trigger plate, installed on the connecting support plate, and the bottom of the trigger plate is connected to the connecting support plate through a rotating shaft;

[0009] An adjusting mechanism, arranged in the cavity of the connecting support plate, the adjusting mechanism is used to adjust the inclination angle of the trigger plate, and a connecting horizontal shaft is installed on one side of the top of the trigger plate.

[0010] Further, the adjusting mechanism includes a driving screw, a meshing sleeve and a synchronous connecting rod. A groove is opened at the top of the connecting support plate, the driving screw is arranged in the groove, the meshing sleeve is meshed and sleeved outside the driving screw, and one end of the synchronous connecting rod is connected to the surface of the meshing sleeve.

[0011] Further, the end of the synchronous connecting rod away from the meshing sleeve is connected to the trigger plate through a rotating shaft.

[0012] Further, the driving screw extends outwards through the connecting support plate to set a handle, a limiting chute is opened at the bottom of the cavity of the driving screw, and a convex block extending into the limiting chute is arranged at the bottom of the meshing sleeve.

[0013] Furthermore, jacks are provided on the surface of the trigger plate, a connecting cross shaft is rotatably installed at the center of the trigger turntable, and a threaded portion is provided at the end of the connecting cross shaft.

[0014] Furthermore, spacing-distributed card slots are provided on the annular outer wall of the trigger turntable, and wear-resistant rubber strips are filled in the card slots.

[0015] Furthermore, a screw hole is provided on the end face of the trigger turntable facing away from the connecting cross shaft, a cover plate screw is spirally installed in the screw hole, a closing cover plate is fixedly provided on the outer wall of the cover plate screw, and a cover plate convex rod is fixedly provided at the center of the closing cover plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In this application, the adjustment mechanism can be used to complete the adjustment of the angle of the trigger plate. Since the trigger plate and the trigger turntable are connected by a connecting cross shaft, therefore, by changing the inclination angle of the trigger plate, the use position of the trigger turntable can be changed, so that the trigger turntable can be adjusted horizontally in front of the travel switch body, and thus the adjustment of the trigger point can be completed, improving the scope of use.
