Side is provided with the outer guide ramp being inclined outwardly from the bottom to top, is provided in the lower end of lower outward flange 7 and coordinates with outer guide ramp
Interior guide ramp 11；The upper inward flange 12 for being sleeved on 1 outside of ontology is provided on the inside of bushing upper end, under upper inward flange 12
It is provided with lower inward flange 13 on the inside of the bushing of side, lower inward flange 13 is interior check device, circulation port 5 and sets the sheet between assembly
1 outside of body is provided with crown interior latch 15 directed downwardly, and the outer latch 14 coordinated with interior latch 15 is arranged in 13 inside of lower inward flange,
Outer latch 14 is engaged with interior latch 15.
The setting of upper outward flange 6, upper inward flange 12, lower outward flange 7 and lower inward flange 13 makes outward flange 6 and lower evagination
Between edge 7, there are gaps between 7 bushing below of lower outward flange and suspension assembly, and make inward flange 12 and lower inward flange 13
Between, there are gaps, the setting in the gap to be cut in shear pin 3 between 13 ontology 1 below of lower inward flange and bushing
It has no progeny, after the resistance of bushing downlink reduces, and shear pin 3 is cut, during bushing downlink, the outer end of stopper 8 and diameter
The spacing being arranged to the outer end of through-hole 9, can be when lower outward flange 7 crosses stopper 8, and stopper 8 is headed into radial through-hole 9
Interior, after outward flange 7 crosses stopper 8 instantly, since wellbore is horizontal well or inclined shaft, stopper 8 can be fallen out of radial through-hole 9
To between bushing and suspension assembly, then stopper 8 is stuck between bushing and suspension assembly, meanwhile, bushing is in downlink process
In, lower inward flange 13 is moved down along interior latch 15, after setting assembly and fully expanding, pressure fluid pressure is reduced, at this point, due to interior
Downward, the engagement of interior latch 15 and outer latch 14 makes lower inward flange 13 be stuck locking to 15 crown of latch, with outward flange 7 at present
It is blocked the blocking of block 8, keeps bushing locked, it can not uplink（As shown in Fig. 6）；Thereby guarantee that the utility model suspension assembly is outstanding
The stability of extension and set the stability that assembly sets packing.
The setting of outer guide ramp and interior guide ramp 11 can cross stopper 8 convenient for lower outward flange 7.

Lower outward flange 7 and lower inward flange 13 are separately positioned on the outside and inside of rib 10.
The practicality of rib type bushing 18 can be further convenient for reducing the resistance of bushing downlink.
The outer end of radial through-hole 9 in outer narrow inner width it is trapezoidal when, can prevent stopper 8 from dropping out outside this hanger.
Meanwhile when downhole temperature increases, down-hole pressure increases, and makes the utility model by upward thrust, due to rib
The material of item 10 is spring steel, and Light deformation can occur for rib 10, can increase between bushing and suspension assembly, bushing with set
Extruding force between assembly keeps this practicality new to reinforce the suspension stability of suspension assembly and set assembly to set stability
Type can be suitable for high temperature hostile operating mode.
