Description
Technical field
This utility model relates to a kind of Fan shape cylinder, belongs to pneumatic element field.
Background technology
Automatic control in the working environment that the operation such as chemical industry, oil refining is higher to safety requirements, to the valve such as butterfly valve, ball valve
System typically will use pneumatic actuator.At present, existing pneumatic actuator mainly has columnar cylinder body, piston, gear and tooth bar
Deng constituting, during work, by piston driving tooth bar, then by rack wheel, become linear motion into rotating.Although it is above-mentioned pneumatic
Executor has the advantages such as thrust is big, effect is steady, but remains structure complexity, production cost height, and gear, tooth bar hold
Flimsy problem.
Utility model content
This utility model, for the needs of current pneumatic cylinder, devises a kind of Fan shape cylinder.
The technical scheme in the invention for solving the technical problem is:
This one Fan shape cylinder, its structure includes: rotating shaft, O, fixing ring, the first cylinder barrel, screw, the second cylinder
Cylinder, piston, nut, stud, packing ring, straight pin；Rotating shaft is circumferentially with the cannelure accommodating O, and rotating shaft is symmetrically distributed in different
The RunddichtringO left and right sides, is coated with the first cylinder barrel outside described fixing ring, the described first cylinder barrel left and right sides is provided with appearance
Receiving the through hole of rotating shaft, described through-hole wall is provided with the cannelure accommodating O, the first cylinder barrel be the laminating of symmetrical two parts and
Becoming, two parts the first cylinder barrel in left and right realizes being connected by screw, and piston is positioned in fixing ring inner chamber.
Described first cylinder barrel lateral surface is coated with the second cylinder barrel, and described second cylinder barrel is realized and the first cylinder barrel by straight pin
It is connected, described first cylinder barrel lateral surface, it is provided with the pin-and-hole coordinated with straight pin.
Described second cylinder barrel one side is provided with the screwed hole accommodating stud, and described stud outer end and nut screw connection, nut leans on
Nearly second cylinder barrel end face coordinates with packing ring.
Described second cylinder barrel lateral surface is provided with the radial reinforcement of casting.
Compared with prior art, the beneficial effects of the utility model are:
1. this utility model simple in construction, unlatching resistance is little, it is tight to seal, and its rotating shaft is directly driven by piston, therefore event
Barrier rate is low, motive force big, reduces component wear, improves the service life of cylinder.
Accompanying drawing explanation
Fig. 1 is the inner mounting structure figure that this utility model is overall；
Fig. 2 is the side view that this utility model is overall.
In Fig. 1 and Fig. 2: rotating shaft 1, O 2, fixing ring the 3, first cylinder barrel 4, screw the 5, second cylinder barrel 6, piston 7,

Detailed description of the invention
As depicted in figs. 1 and 2: a kind of Fan shape cylinder, its structure includes: rotating shaft 1, O 2, fixing ring 3, first
Cylinder barrel 4, screw the 5, second cylinder barrel 6, piston 7, nut 8, stud 9, packing ring 10, straight pin 11；Rotating shaft 1 is circumferentially with receiving O type
The cannelure of circle 2, rotating shaft 1 is symmetrically distributed in fixing ring 3 left and right sides, is coated with first outside described fixing ring 3
Cylinder barrel 4, described first cylinder barrel 4 left and right sides is provided with the through hole accommodating rotating shaft 1, and described through-hole wall is provided with the ring accommodating O 2
Shape groove, the first cylinder barrel 4 forms for the laminating of symmetrical two parts, and left and right two parts the first cylinder barrel 4 realizes being connected by screw 5,
Piston 7 is positioned in fixing ring 3 inner chamber；Described first cylinder barrel 4 lateral surface is coated with the second cylinder barrel 6, and described second cylinder barrel 6 leads to
Cross straight pin 11 to realize being connected with the first cylinder barrel 4, described first cylinder barrel 4 lateral surface, be provided with the pin-and-hole coordinated with straight pin 11；Institute
Stating the second cylinder barrel 6 one side and be provided with the screwed hole accommodating stud 9, described stud 9 outer end coordinates with nut 8, and nut 8 is near second
Cylinder barrel 6 end face coordinates with packing ring 10；Described second cylinder barrel 6 lateral surface is provided with the radial reinforcement of casting.
A kind of Fan shape cylinder described by the present embodiment, simple in construction, unlatching resistance is little, it is tight to seal, and its rotating shaft 1 is direct
Being driven by piston 7, therefore failure rate is low, motive force greatly, reduce component wear, improve the service life of cylinder
The above, detailed description of the invention the most of the present utility model, those of ordinary skill in the art are new in this practicality
In the range of type discloses, the change that can readily occur in, all should contain within the protection domain of utility model.
