In order to solve the problems, the rotating shaft of the electric actuator is specially manufactured, which has more accurate control, firmer positioning shaft and no damage to the positioning switch.
In order to achieve the above object, the present invention provides the following solutions: the electric actuator rotating shaft comprises a plug shaft and a switch control shaft, the plug shaft is sleeved on an electric actuator shell, a slot used for being connected with a control valve is arranged in the middle of the plug shaft, the switch control shaft is arranged in the electric actuator shell, and a control structure used for controlling the on-off of a rotary switch of the electric actuator is arranged on the switch control shaft.
Furthermore, the control structure comprises a convex structure and a concave structure, and the distance between the convex structure and the axle center of the switch control shaft is larger than the distance between the concave structure and the axle center of the switch control shaft.
Further, the recessed structure includes a plurality of longitudinal grooves disposed along the surface of the switch control shaft.
Further, the number of the longitudinal grooves is two, and an included angle formed between the longitudinal grooves and the longitudinal grooves is 180 degrees.
Furthermore, the concave structure is a concave surface which longitudinally penetrates through two sides of the switch control shaft.
Further, the concave structure is a concave arc groove which is arranged in the middle of the surface of the switch control shaft.
The utility model discloses an useful part lies in:
the utility model provides an electric actuator pivot, its control structure and pivot body structure as an organic whole, through setting up recessed structure at the switch control axle, when micro-gap switch is in recessed structure, micro-gap switch is released, along with electric actuator rotates, micro-gap switch leaves recessed structure, then micro-gap switch is pushed down again, through setting up different recessed structure, can realize different micro-gap switch control function.

Reference numerals: the switch comprises a switch control shaft 1, a plug shaft 2, a slot 3, a longitudinal groove 4, a lower concave surface 5, a lower concave arc groove 6, a circuit board 101, a microswitch 102 and a connecting line 103.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 5 of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Electric actuator pivot, including connecing inserting shaft 2 and on-off control axle 1, connect and insert 2 covers of shaft and establish on the electric actuator casing, connect and insert and be equipped with the slot 3 that is used for being connected with the control valve in the middle of shaft 2, on-off control axle 1 sets up in the electric actuator casing, is equipped with the control structure who is used for controlling electric actuator rotary switch break-make on-off control axle 1. The control structure comprises a convex structure and a concave structure, and the distance between the convex structure and the axis of the switch control shaft 1 is larger than the distance between the concave structure and the axis of the switch control shaft 1.
The first embodiment is as follows:
the concave structure comprises a plurality of longitudinal grooves 4, and the longitudinal grooves 4 are arranged along the surface of the switch control shaft 1. According to the setting condition of the micro switch 102, the setting quantity and distribution of the longitudinal grooves 4 can be adjusted correspondingly, and the switch control shaft 1 adopting the structure of the longitudinal grooves 4 is more suitable for the micro switch 102 controlled by an electric motor due to narrow groove width.
Example two:
the concave structure is a concave surface 5, and the concave surface 5 longitudinally penetrates through two sides of the switch control shaft 1. The lower concave surface 5 is a continuous concave cambered surface, and longitudinally penetrates through the concave surface, and is controlled in a non-inching mode, the micro switch 102 is in a convex structure or a concave structure, the micro switch 102 and the switch control shaft 1 have larger contact area, and when the micro switch 102 is transited from the lower concave surface 5 to the convex surface, the transition surface is also a cambered surface, the structure can adapt to the arrangement of the micro switch 102 with different longitudinal heights, and meanwhile, the service life of the micro switch 102 and the service life of the rotating shaft can be prolonged.
Example three:
the concave structure is a concave arc groove 6, and the concave arc groove 6 is arranged in the middle of the surface of the switch control shaft 1. The configuration may be adapted when the longitudinal height of the microswitch 102 is substantially fixed. In addition, according to the arrangement number and the arrangement positions of the micro switches 102, a plurality of concave arc grooves 6 with different heights can be arranged, and a plurality of micro switches 102 can be controlled simultaneously.
It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
