Hack lever, lower end is expanding wing cylinder base platform, upper end is that expanding wing cylinder limit is presented a theatrical performance as the last item on a programme, wing cylinder is by there is longitudinal fin on outer wall
The opposite clamping watt cylinder of two panels constitute, on set tankage of the wing jacket casing loaded on bridge cylinder rod segment stage casing.
It is set in two opposite grafting planes at the two panels watt cylinder both ends as a further improvement of the utility model,
There is a pair of of convex-concave longitudinal direction grafting keyway, also respectively have a pair of lateral convex-concave lock-bit keyway, is all provided on wing cylinder base platform and limit are presented a theatrical performance as the last item on a programme
Have radial with the mutually fixed top wire hole of sucker rod, the pier for being fixedly connected half arc is longitudinally extended in the upper surface that limit is presented a theatrical performance as the last item on a programme
Platform.
The line of increasing friction force is equipped on the inner surface of two panels watt cylinder as a further improvement of the utility model,
Reason.
It is all provided on the interface of the two panels clamping watt cylinder of the composition wing cylinder as a further improvement of the utility model,
There are longitudinal locking keyway for being mutually convex-concave, two panels clamping watt cylinder to shrink clamping into a tubular and be tightly fixed in bridge stage casing
On the hack lever of undergauge.
The periphery of the wing cylinder sets 1 or more longitudinal fin, and each wing as a further improvement of the utility model,
The outer rim of piece protrudes from the periphery of bridge and wing cylinder.
The oil pumping rod centering device of the easy disassembly of the utility model effectively increases the integral strength of centralizer, lining
Texture formula surface so that it is more firmly mounted, neither sliding will not fall off.It shrinks the structure of clamping, design structure letter
It is single, easy for installation, good centralizing function is played to sucker rod, rod and tube partial-wear can be effectively prevent, extend sucker rod uses the longevity
Life improves the reliability of rod-pumped well oil extraction system.
