SUMMERY OF THE UTILITY MODEL
The utility model discloses the aforesaid to prior art exists is not enough, provides a rational in infrastructure's sucker rod toper coupling becomes spiral-lock and puts.
The utility model aims at realizing through the following technical scheme:
a conical coupling buckle changing device of a sucker rod comprises a conical coupling buckle, a first fixed connecting lug, a first auxiliary connecting rod, a first fastening connecting sleeve, a first fastening screw rod, a second fixed connecting lug, a second auxiliary connecting rod and a second fastening connecting sleeve, wherein a first internal thread is arranged inside the conical coupling buckle, a coupling diameter changing hole is arranged at the lower part of the first internal thread, the coupling diameter changing hole is a conical hole, a second internal thread is arranged at the lower part of the coupling diameter changing hole, two pipe wrench fixing grooves are formed in the outer side of the conical coupling buckle, the pipe wrench fixing grooves are symmetrically arranged, an identification dimension surface is arranged at the bottom of the conical coupling buckle, two first fixed connecting lugs are arranged at the upper part of the conical coupling buckle, the first fixed connecting lugs are symmetrically arranged, the first auxiliary connecting rod is connected inside the first fixed connecting lugs through a rotating shaft, and the first auxiliary connecting rod rotates on the rotating shaft, the upper part of the first auxiliary connecting rod is provided with a first fastening connecting sleeve, and the first fastening connecting sleeve is connected with a corresponding first fastening connecting sleeve through a first fastening screw rod.
The conical coupling becomes to detain the lower part and has two No. two fixed connection ears, No. two fixed connection ears symmetry sets up, and No. two auxiliary connecting rods are connected through the pivot in No. two fixed connection ears are inside.
The second auxiliary connecting rod rotates on the rotating shaft, a second fastening connecting sleeve is arranged at the lower part of the second auxiliary connecting rod, and the second fastening connecting sleeve is connected with the corresponding second fastening connecting sleeve through a second fastening screw rod.
Has the advantages that:
when the conical coupling is buckled to change the diameter of the down-hole sucker rod string, the contact area between the conical coupling buckle change and the down-hole sucker rod string is increased under the combined action of the first auxiliary connecting rod and the second auxiliary connecting rod when the conical coupling buckle change is connected with the down-hole sucker rod string, so that the conical coupling buckle change is more stable in connection with the down-hole sucker rod string, the integral structure is more reasonable, the internal and external threads are not required to be frequently used for alternative connection, the material cost is reduced, meanwhile, the problem that the sucker rod string is tripped due to the fact that manual tightening torque is uneven due to frequent use of excessive reducing in the prior construction is solved, the labor intensity of workers is greatly reduced, the integral structure is more reasonable, the single-well rework rate is greatly reduced, and the material cost can be better saved due to lower manufacturing cost.
