Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is a kind of not by the pneumatic actuator of load effect, including body 1, the fixed peace in the front of body 1 referring to FIG. 1-2,
Equipped with control switch 2, the top of control switch 2 offers air inlet 3, and the left side of control switch 2 offers gas outlet 4, control
The left side of the switch 2 and top for being located at gas outlet 4 offers connection socket 5, there are two connection sockets 5, and connection socket 5 is uniform
It is distributed in the left and right sides of control switch 2, the left and right sides of body 1 is fixedly installed with side cover 6, the lateral wall of two side covers 6
Exhaust outlet 7 is offered, the diameter of exhaust outlet 7 is identical as the diameter of connection socket 5, and pacifies between exhaust outlet 7 and connection socket 5
Equipped with connecting tube, the top of body 1 is fixedly installed with beam circle 8, and the top of beam circle 8 is fixedly installed with link block 9, link block 9
The left and right sides offers wedge groove 10, and the top of link block 9 is fixedly installed with connecting screw 11, the lateral wall of connecting screw 11
It is socketed with backing plate 12, backing plate 12 is U-board, and connecting screw 11 is threadedly coupled with backing plate 12, the top movable peace of connecting screw 11
Equipped with pedestal 13, backing plate 11 and 1 junction of body are fixedly installed with stud 14, and there are two studs 14, and double end spiral shell
Bolt 14 is evenly distributed on the left and right sides of backing plate 12, and the lateral wall of stud 14 is socketed with stripped thread 15, stud 14 it is outer
Side wall and be located at stripped thread 15 top be threaded with fixture nut 16, the top of pedestal 13 is fixedly installed with controller 17, even
Screw rod 11 and 13 grafting of pedestal are connect, controller 17 is connect through pedestal 13 with connecting screw 11, by the way that backing plate 12 is arranged, when pneumatic
Actuator goes wrong, the fixture nut that first comes loose 16, releases the limitation of part on stud 14, then turns stud
14, stud 14 is extracted into body 1, is rotated further by backing plate 12, backing plate 12 is moved up with the screw thread of connecting screw 11, moved to
Certain altitude, then tool is caught in wedge groove 10, link block 9 is turned, to close transfer passage, is pneumatically held by manually adjusting
Row mechanism avoids output superfluous, causes economic loss.
In conclusion this is not by the pneumatic actuator of load effect, by the way that backing plate 12 is arranged, when pneumatic actuator is asked
Topic, the fixture nut that first comes loose 16 release the limitation of part on stud 14, stud 14 are then turned, by stud
