The blind via bottom is flush end, and it is positive and negative against being positioned at the flush end of blind via bottom that butterfly spring is divided into group；It is described
The cylindrical of butterfly spring leaves space between the inwall of blind hole, meets the amount extended laterally in butterfly spring telescopic process.
Fastening screw thread is equipped with the outside of the blind hole and on the outside of round nut, two fastenings are formed with screw thread matches mutually
Screw thread pair so that contiguous block is fastened to each other with round nut.
The inner side of the round nut bottom is provided with sphere, and center is provided with circular inner hole, and edge, which is additionally provided with, tightens hole.
The buffer stopper is made up of the first cylinder, step and the second cylinder；The inner circle gap of first cylinder and butterfly spring
Coordinate；The circular inner hole of second cylinder and round nut is slidably connected, end and the caging bolt Intermittent Contact of the second cylinder.
Described step one end is the first sphere B, and the other end is the second sphere C, and centre is face of cylinder A, the first sphere B and butterfly
The inner circular balling-up contact of shape spring, the second sphere C contact with the spheric balling-up of round nut bottom.
Beneficial effects of the present invention：Angle stroke cylinder protecting against shock buffer gear of the present invention uses butterfly spring group conduct
Kinetic energy absorption and releasing member, protecting against shock and buffering positive effect, and cushion stroke is small, disclosure satisfy that quick acting requirement.Should
Protecting against shock buffer gear is simple in construction, and required installing space is small, non-maintaining, and is easily changed.Design and manufacture cost is relatively low,
The operating life of valve and cylinder can be greatly improved.

Embodiment
As Figure 1-5：A kind of angle stroke cylinder protecting against shock buffer gear, including cylinder 1 and casing 2, it is provided with casing 2
The piston rod 8 being connected with cylinder 1, one end of piston rod 8 are connected with contiguous block 3；The contiguous block 3 slides on guide rod 9；
The end of casing 2 is additionally provided with caging bolt 7；
The contiguous block 3 is provided with blind hole 10, several butterfly springs 4 is provided with blind hole 10, in the inner circle of butterfly spring 4
In be provided with buffer stopper 5, round nut 6 is additionally provided with blind hole 10, buffer stopper 5 can move axially in round nut 6.
The bottom of blind hole 10 is flush end, and butterfly spring 4 is divided into the positive opposition of group according to different pretightning forces and the needs of stroke
And be positioned at the flush end of the bottom of blind hole 10；Space is left between the inwall of the cylindrical and blind hole 10 of the butterfly spring 4, is met
The amount extended laterally in the telescopic process of butterfly spring 4.
The outside of blind hole 10 and the outside of round nut 6 are equipped with fastening screw thread, and screw thread matches mutually is used in two fastenings
Form screw thread pair so that contiguous block 3 and round nut 6 are fastened to each other.
The inner side of the bottom of round nut 6 is provided with sphere 6-1, and center is provided with circular inner hole 6-2.Also set on round nut 6
Hole 6-3 is tightened, round nut 6 is fixed on contiguous block 3 by tightening hole 6-3.
The buffer stopper 5 is made up of the first cylinder 5-1, step 5-2 and the second cylinder 5-3；First cylinder 5-1 and butterfly bullet
The inner circle gap of spring 4 coordinates；Second cylinder 5-3 and round nut 6 circular inner hole 6-2 are slidably connected, and play the axle of buffer stopper
To positioning action；Second cylinder 5-3 end and the Intermittent Contact of caging bolt 7.
Described step 5-2 one end is the first sphere B, and the other end is the second sphere C, and centre is face of cylinder A, the first sphere B
Contacted with the inner circular balling-up of butterfly spring 4, positioning action is played to butterfly spring 4；Second sphere C and the bottom of round nut 6
Sphere 6-1 forms ball contact.
The present invention operation principle be：During the action of angle stroke cylinder, contiguous block 3 is run to stroke end, and the of buffer stopper 5
Two cylinder 5-3 end face contacts with caging bolt 7；Buffer stopper 5 compresses butterfly spring 4 toward transporting inside contiguous block 3 after being hit
It is dynamic, because reaction force be present in butterfly spring 4 so that the process of dynamic pressure contracting butterfly spring 4 needs to consume the work of angle stroke cylinder
Firmly, after butterfly spring 4 is by compression S1 strokes, to the stroke end of butterfly spring 4.This process is to slow down angle stroke gas
Cylinder makees process, has both realized protecting against shock pooling feature.Conversely, when angle stroke cylinder counteragent, due to needing to discharge butterfly bullet
The compressed action of spring 4, need also exist for consuming the active force of angle stroke cylinder, you can realize protecting against shock buffering effect when valve is opened
Fruit.
