Fig. 2 is a cross-sectional view of the present invention.
Detailed Description
As shown in fig. 1-2, an oil pipe hanger upper end locknut extracting tool comprises a lantern ring 1, a plurality of grooves 14 are uniformly formed in the circumference of the outer side of the lantern ring 1, a rotating rod 2 is rotatably arranged in each groove 14, the end portion of the rotating rod 2 in each groove 14 is arc-shaped, an arc-shaped convex block 3 is fixed at the end portion of the rotating rod 2 in each groove 14, a stop lever 4 is arranged on the lantern ring 1 on the inner side of each groove 14 in a sliding mode, the length direction of each stop lever 4 is parallel to the radial direction of the lantern ring 1, the section of each stop lever 4 is rectangular, each stop lever 4 is made of hard alloy materials, a sliding block 12 is fixed at the lower end of each stop lever 4, each sliding block 12 is arranged in a sliding groove 11 in the lantern ring 1 in a sliding mode, a second spring 13 is installed between each sliding block 12 and.
All seted up passageway 17 on the relative both sides wall of recess 14, passageway 17 includes the straight portion of the vertical portion of top and below, and the round pin axle 16 all is fixed with to the rotary rod 2 both sides in the recess 14, and round pin axle 16 rotates the setting in recess 14 through the straight portion back that the vertical portion of passageway 17 entered into passageway 17.
When the utility model is used, the lantern ring 1 is sleeved on the upper-end locknut, then the stop lever 4 is corresponding to the key groove of the upper-end locknut, then the rotary rod 2 is rotated, the rotary rod 2 is parallel to the horizontal plane, when the rotary rod 2 is rotated, the stop lever 4 moves towards the center direction of the lantern ring 1 under the action of the arc-shaped lug 3, the end part of the stop lever 4 enters into the key groove of the upper-end locknut, after the butt end of the stop lever 4 enters into the notch 15 on the arc-shaped lug 3, under the elastic action of the second spring 13, the rotary rod 2 is stabilized, at the moment, the lantern ring 1 can be rotated by the rotary rod 2, so that the upper-end locknut is disassembled by the stop lever 4, when the upper-end locknut is loosened and rotated, the rotary rod 2 on the lantern ring 1 can partially rotate and is vertical to the ground, thereby preventing other devices from blocking the rotary rod 2, thereby increasing, the disassembly efficiency is improved.
