Problems solved by technology

There is no up and down movement when reciprocating in the horizontal direction, causing the surface of the roller 8 and the switch 11 to fail to reach a full contact state during the test process. If the position adjustment is not accurate, it will easily cause the switch action error

Abstract

The invention relates to a joystick for testing the service life of a switch. A main body is a reciprocating motion device, a reciprocating motion rod is extended from one side of the reciprocating motion device, and the head part of the reciprocating motion rod is connected with the joystick. The joystick for testing the service life of the switch is characterized by comprising a base, a screw, a roller and a pin shaft, wherein one side of the base is fork-shaped and is divided into two supporting plates; U-shaped through holes are formed in the middle of the supporting plates; a sliding block is arranged in the through holes, and a reciprocating mechanism is arranged above the sliding block; the screw is arranged on the other side of the base; the roller is arranged inside the fork-shaped supporting plate on one side of the base; and the pin shaft is used for stringing the sliding block and the roller which are arranged in the supporting plates. When the joystick with the structure is set to test the service life of the switch, the switch actuates to ensure that the joystick performs reciprocating motion along the horizontal direction, the roller is supported by a pressure spring and can move up and down, and the full contact between the roller and the surface of the switch is always kept, so the accuracy of the test is improved.

Description

technical field [0001] The invention relates to a device for testing the service life of a switch, in particular to a joystick for improving testing accuracy. Background technique [0002] At present, the main body of the equipment used to test the service life of rocker type power switches is a reciprocating device, and a joystick is installed on the head of the moving rod on one side of the reciprocating device, such as Figure 7 As shown, the existing joystick is mainly composed of a roller 8, a pin 9 and a connecting rod 10, and the roller 8 is directly fixed on one end of the connecting rod 10 through the pin 9, and this device is connected to directly fix the roller 8 on the horizontal direction. scrolling, while testing, such as Figure 8 As shown, the connecting rod 10 moves back and forth in the horizontal direction, and from the three actions of the same switch, one is to disconnect, at this time, the joystick is on the left, and when the joystick moves to the righ...
