(2) The utility model discloses the sleeve can audio-visually see the position that the reinforcing bar was put into the sleeve in the work progress, avoided "leaking in the past construction to twist" or "surpass and twist" scheduling problem, guaranteed construction quality. Meanwhile, the problems of serious distortion and bending which possibly exist in the original construction process are avoided, and the construction quality is further ensured.

(3) The utility model discloses steel sleeve, rational in infrastructure, easy and simple to handle, the atress performance is good, and the safety and stability is good, and this telescopic theory of operation is easily understood moreover, has wide popularization market and application prospect.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a rotatable slipknot type coupling assembling, including the lower part steel sleeve and the rotatable upper portion steel sleeve that the longitudinal symmetry set up, upper portion steel sleeve and lower part steel sleeve inboard and outside all are provided with the screw thread, and upper portion steel sleeve is connected through 1 articulated of round pin axle with one side of lower part steel sleeve, and the opposite side passes through semicircle protruding buckle 9 and connects.

As shown in fig. 6, 7 and 8, the lower steel bar sleeve comprises a solid section 5, one side of the lower half part of the solid section 5 is connected with a lower threaded sleeve 8, the upper half part of the solid section 5 is provided with a step structure, a convex semicircle I6 and a convex semicircle II7 are sequentially arranged on the step structure from inside to outside, and the diameter of the convex semicircle I6 is smaller than that of the convex semicircle II 7.

As shown in fig. 3, 4 and 5, the upper reinforcing steel bar sleeve comprises a thick-wall semicircular clip 2, a thin-wall semicircular clip 3 and an upper threaded sleeve 4 which are sequentially arranged from left to right, the inner diameter of the thick-wall semicircular clip 2 is the same as the diameter of the protruding semicircle I6, and the inner diameter of the thin-wall semicircular clip 3 is the same as the diameter of the protruding semicircle II 7. The central angle of the thick-wall semicircular clip 2 and the thin-wall semicircular clip 3 is larger than 180 degrees. Teeth formed between the thick-wall semicircular card 2 and the thin-wall semicircular card 3 are meshed with grooves between the convex semicircular I6 and the convex semicircular II7, and finally a prestress system is formed through the connection of the semicircular clamping part 9, so that the structure is more stable.

The semicircular convex buckle 9 comprises a semicircular groove arranged on the outer side of the upper steel bar sleeve and a semicircular convex buckle arranged on the outer side of the lower steel bar sleeve, the semicircular groove and the semicircular convex buckle are provided with a plurality of groups, and the semicircular grooves and the semicircular convex buckles of the plurality of groups are in one-to-one correspondence arrangement.

Specifically, when the steel bar with the thread at the end to be fixed is fixed, the upper part of the rotatable threaded sleeve is opened, the thread at the end of the steel bar is directly matched with the thread inside the sleeve, and meanwhile, the thread of the steel bar at the other end is matched with the thread.

Then, the upper rotatable steel bar sleeve is closed and buckled on the steel bar, wherein the thick-wall semicircular clip 2 corresponds to the protruding semicircle II 6; the thin-wall semicircular card 3 corresponds to the convex semicircular card II 7.
