For solving the problem, the utility model provides a kind of reinforced steel bar straight thread coupling sleeve, comprising: inwall is established female body and is arranged on described body two ends, is suitable for stopping that tightening tool departs from the block piece of described body along the axis of described body.
Optionally, described block piece is hollow cylinder, and the internal diameter of described hollow cylinder is equal with the internal diameter of described body, and the external diameter of described hollow cylinder is greater than the external diameter of described body.
Optionally, described block piece is hollow regular prism, and the internal diameter of described hollow regular prism is equal with the internal diameter of described body.
Optionally, described regular prism is four-prism.
Optionally, the cross section of the outer wall of described body is regular polygon.
Optionally, the cross section of the outer wall of described body is regular hexagon.
Optionally, the outer wall of described body is provided with at least three ribs being uniformly distributed, protruding.
Compared with prior art, the utility model has the following advantages:
The reinforced steel bar straight thread coupling sleeve that the utility model provides, by the two ends at body, block piece is set, tightening tool can be enclosed within body rapidly and accurately in the process of installing straight thread joint, and tightening tool can not depart from along the axis of body when rotating, thus improve construction quality and efficiency of construction.
In possibility of the present utility model, the cross section of the outer wall of described body is regular hexagon, tightening tool can be adopted in the process of installing straight thread joint like a cork to reach the maximum of connection regulation and to screw moment, and there will not be tightening tool skid along the radial direction of body and be connected situation not in place, improve construction quality and efficiency of construction further.
In possibility of the present utility model, the outer wall of described body be provided with at least three be uniformly distributed, the rib that protrudes as the origin of force of tightening tool, prevent tightening tool from skidding along the radial direction of body, improve construction quality and efficiency of construction further.
