Description
Technical Field
The utility model relates to an executor prevent mistake operating structure.
Background
At present, an actuator fine adjustment device provided in the market generally comprises an actuator output shaft, a guide shaft and an end cover, wherein the output shaft and the guide shaft are connected through a bolt, open grooves are formed in two sides of the guide shaft, a through hole aligned with the open grooves is formed in the end cover, a first gear shaft is movably arranged in the open groove on one side, a second gear shaft is movably arranged in the open groove on the other side, the upper ends of the first gear shaft and the second gear shaft extend into the through hole, a first rotating part and a second rotating part are sleeved on the guide shaft, convex blocks are arranged on the first rotating part and the second rotating part respectively, an inner gear of the first rotating part is meshed with the first gear shaft, an inner gear of the second rotating part is meshed with the second gear shaft, a third rotating part and a fourth rotating part are further sleeved on the guide shaft, an inner ring of the third rotating part is provided, an anti-rotation sleeve provided with a rubber damping ring is arranged between the first rotating piece and the second rotating piece.
Above-mentioned executor structure is complicated and rotates the third during use or the fourth rotates the piece and drives first rotation piece or the rotation of second, makes the lug top move micro-gap switch to reach the purpose of opening or closing the valve, anybody all can rotate the third rotation piece or the fourth rotates the piece, produces the maloperation easily, uses rubber damping circle easy ageing after a period in addition, and structural stability is relatively poor, and first rotation piece and second rotate the piece and produce easily and rotate, and then produce the maloperation.
Disclosure of Invention
In view of the deficiency of the background art, the technical problem to be solved by the utility model is to provide a simple structure, be difficult for producing maloperation and the longer executor of life prevent mistake operation structure.
Therefore, the utility model discloses an adopt following technical scheme to realize:
the anti-misoperation structure of executor, including executor output shaft, guiding axle and end cover, output shaft and guiding axle pass through bolted connection, the guiding axle both sides are equipped with the open slot, the cover is equipped with first rotation piece and second rotation piece on the guiding axle, the outer lane that first rotation piece and second rotated the piece all is equipped with lug, circles and is equipped with a plurality of teeth, characterized by: a first key is movably inserted into the open slot on one side, a second key is movably inserted into the open slot on the other side, a first gear capable of being meshed with teeth of the first rotating part is arranged on the first key, and a second gear capable of being meshed with teeth of the second rotating part is arranged on the second key.
Furthermore, the upper parts of the first key and the second key are both provided with through holes.
Furthermore, an anti-rotation sleeve is arranged between the first rotating piece and the second rotating piece, an annular groove is formed in the upper end and the lower end of the anti-rotation sleeve, and a waveform gasket is arranged in the annular groove.
After the technical scheme is adopted, the sealing cover is firstly opened when the valve needs to be opened and closed, then the first key or the second key is inserted into the corresponding open slot, then the first key or the second key is rotated to drive the first rotating piece and the second rotating piece, so that the convex block pushes the micro switch, the purpose of opening or closing the valve is achieved, when the valve is not used, the first key or the second key is pulled out and hung at a specific position through the through hole, the structure is simple and is not easy to generate misoperation, in addition, the wave-shaped gasket is arranged in the annular groove at the lower end of the anti-rotating sleeve, the wave-shaped gasket has good elasticity, impact resistance and other performances, the valve is not easy to age, the first rotating piece and the second rotating piece are not easy to generate rotation, the misoperation is not easy to generate, and.
