Abstract
The utility model provides an outer shell type weighted lever that outer shell type weighted lever specifically is the weighted lever with elasticity dop chucking cable, and this kind of weighted lever is by the hollow bar, and the elasticity dop is pressed the cap to constitute one and is leaned on elasticity dop chucking.
Description
Technical field
The utility model patent relates to oil field Cut-and-thread fishing field of operation, specifically a kind of jacket-type cable weighted lever, and it is through on logging cable, to the use that cable increases the weight of, makes snap joint quickly through drilling tool water hole, can improve the speed of Cut-and-thread fishing operation.
Background technology
At present, existing weighted lever axially opens groove at metal bar, and cable is placed in groove, then with lateral pin, cable pushed down, and one of shortcoming is that pin is easily lost, two be weighted lever on cable fixing loosely, easily vibration up and down.
Summary of the invention
This patent, in order to overcome the deficiency of above-mentioned weighted lever, provides a kind of jacket-type weighted lever, and specifically with the weighted lever of elastic chuck clamping cable, this weighted lever is by hollow stem, and elastic chuck, pressure cap forms a jacket-type weighted lever by elastic chuck clamping.
This patent for the technical scheme realizing its technical problem and adopt is: in hollow stem, have cable via hole, round taper hole is had in one end of hollow stem, there is box thread the end of round taper hole, there is taper seat the end of elastic chuck, taper seat is consistent with the tapering of round taper hole, pressure cap promotes elastic chuck and moves axially, and by the interaction of round taper hole and taper seat, achieves the clamping of the utility model jacket-type weighted lever on cable and fixes.
The object of the utility model patent is: in the Cut-and-thread fishing operation process of oil field, provides more rational, practical, instrument equipment safe and reliable easily.
The beneficial effect of the utility model patent is: make Cut-and-thread fishing operation more convenient, safe and reliable, reduces risk.
