Description

technical field

Background technique

The joystick is a common operating mechanism used to control industrial equipment such as robots, medical equipment, optical instruments, photographic lamp equipment, mobile machinery, etc. It generally returns automatically through its own elastic mechanism.

However, in actual use, if the joystick needs to be shaken to a certain position for a long time to maintain a certain movement of the controlled machine, it is necessary for the person to hold the stick body with his hand and keep it still, which brings great inconvenience to the operator. Physical exertion, but even so, it is difficult to ensure that the signal output by the joystick is always constant, because holding it for a long time will inevitably shake a little.

The quick-release locking clip 13 can open/lock the end of the second connecting rod 12 away from the second rotating shaft 16. When in use, loosen and release the locking clip 13. At this time, the second connecting rod 12 is opened, and the first connecting rod 11 and The second connecting rod 12 is movable. After the joystick base is snapped into the base, the second connecting rod 12 is locked with the quick release locking clip 13, and the joystick base is locked in the joystick base locking mechanism.

In the joystick traction mechanism 2 shown in Figure 3, the transmission guide rod 20 is L-shaped and can move in a direction parallel to the first axis 37 on the base 10. The specific fixing method can be through a direction parallel to the first axis 37. 2-4 axles are fixed on the base 10. One end of the rocking arm 21 is hinged on one side of the transmission guide rod 20 through the fourth rotating shaft 23 , and the other end is hinged with the joystick holder 24 through the third rotating shaft 22 . The joystick holder 24 can clamp the joystick. When in use, open the thumb screw 241, buckle the first fixed arm 240 of the joystick into the body of the joystick, then wrap the body of the joystick with the second fixed arm 243 of the joystick, and manually Twist the screw 241 tightly, and the joystick is fixed.
