The axial distance between the two first notches 1-2 is 3 cm, so that two connection points of the first connector 1 and the second connector 2 are prevented from being too close, and the connection effect of the first connector 1 and the second connector 2 is further improved.
And a fastening threaded hole 2-4 matched and connected with a fastening screw is arranged at the axial second end of the second connecting body 2 along the radial direction, and the fastening threaded hole 2-4 is arranged between the two second notches 2-2. After the steel bar connecting sleeve completes the connection of the two steel bars, the first connecting body 1 and the second connecting body 2 can be fixedly connected through the fastening screw and the fastening threaded hole 2-4, so that the structural stability of the steel bar connecting sleeve is further improved, and the connecting effect of the steel bars is good.
The sum of the depths of the first notch 1-2 and the second notch 2-2 is equal to the diameter of the ball 3, and the widths of the first notch 1-2 and the second notch 2-2 are equal to the diameter of the ball 3. The utility model discloses in the first notch 1-2 of this structure, second notch 2-2 and ball 3 make the periphery wall of the axial second end of first connector 1 be connected with the pore wall laminating of the pilot hole of second connector 2 on the one hand to make first connector 1 and second connector 2 can not take place radial shift, on the other hand makes first connector 1 and second connector 2 can not take place axial shift, thereby make first connector 1 and second connector 2's rotatory effect better.
An oil guide groove 2-5 communicated with the second notch 2-2 is axially formed in the hole wall of the assembling hole, and a small amount of lubricating oil can be put into the first notch 1-2 and the second notch 2-2 through the oil guide groove 2-5 before the steel bar connecting sleeve is used, so that the rotating smoothness of the first connecting body 1 and the second connecting body 2 is better, and the using effect of the steel bar connecting sleeve is further improved.
The axial length of first screw hole 1-1 equals the axial length of second screw hole 2-1 for every reinforcing bar equals with bar connection sleeve's connection length, and then has improved once more the utility model discloses bar connection sleeve and the connection effect of reinforcing bar.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
