[0002] As is well known, the steel bar connecting sleeve is an indispensable connecting piece in construction engineering. The steel bar connecting sleeve belongs to the mechanical connection in the steel bar connection method and is suitable for the connection between large-diameter steel bars. It has the characteristics of energy saving and being not restricted by the composition and type of steel bars.

[0003] During the construction process, the laying angles of steel bars are various. Especially when the steel bars are vertically connected, the current sleeve is first screwed onto the steel bar, and then the threaded part of the extended steel bar is aligned with the sleeve and screwed in to realize the connection of the two steel bars. Due to the large weight and long length of the steel bar, it is difficult for the construction workers to accurately control the direction of the extended steel bar vertically. As a result, during the process of screwing the extended steel bar into the sleeve, the construction workers need to rotate the extended steel bar multiple times to complete the installation, which affects the construction speed.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, for the present utility model, a steel bar connecting sleeve that is convenient for disassembly and assembly, includes a threaded barrel 1. Both ends of the threaded barrel 1 are provided with openings, and through the internal threads in the threaded barrel 1, the threaded parts of steel bars can be connected to both ends. One end of the threaded barrel 1 is fixedly connected to a stabilizing tube 2. The inner diameter of the threaded barrel 1 is smaller than the inner diameter of the stabilizing tube 2, so that the threaded part of the extended steel bar can enter the stabilizing tube 2.

[0024] Two corresponding supporting pieces 3 are arranged in the stabilizing tube 2. On the sides of the two supporting pieces 3 that are far away from each other, sliding rods 4 that are slidably connected to the stabilizing tube 2 are connected. The outer wall of the sliding rod 4 is provided with multiple equal surfaces, so that when the sliding rod 4 slides on the stabilizing tube 2, the sliding rod 4 can be prevented from rotating. One end of each sliding rod 4 is vertically connected to a connecting plate 5. On the corresponding sides of the two connecting plates 5, threaded tubes 6 are connected. The same rotating assembly is installed on the two threaded tubes 6.

[0025] The rotating assembly includes a rotating block 7. Threaded rods 8 with opposite thread directions are fixedly connected to both sides of the rotating block 7. The threaded rods 8 are threadedly connected to the threaded tubes 6. By driving the rotation of the rotating block 7, the threaded rods 8 drive the threaded tubes 6 to move away from or close to each other. At the same time, the connecting plates 5 drive the sliding rods 4 to slide on the stabilizing tube 2, so that the two supporting pieces 3 move close to or away from each other.

[0026] When the two supporting pieces 3 are in contact, they can form a circular tube shape, and its inner diameter is equal to the outer diameter of the threaded part of the steel bar, so that the extended steel bar can slide stably between the two supporting pieces 3 and prevent angle deviation.

[0027] The outer wall of the end of the threaded barrel 1 far away from the stabilizing tube 2 is provided with a first anti-slip part 9. The outer wall of the end of the stabilizing tube 2 far away from the threaded barrel 1 is provided with a second anti-slip part 10. The first anti-slip part and the second anti-slip part are respectively a plurality of equal surfaces arranged around the outer walls of the threaded barrel and the stabilizing tube, so as to facilitate the operation tool to clamp the threaded barrel or the stabilizing tube.

[0028] In summary, when using this steel bar connecting sleeve that is convenient for disassembly and assembly, first screw the end of the threaded barrel 1 close to the first anti-slip part 9 onto the threaded part of the fixed steel bar, and then clamp the second anti-slip part 10 with an operation tool and rotate the stabilizing tube 2 to make the threaded part of the fixed steel bar enter the threaded barrel 1 for a certain distance;

[0029] Place the threaded part of the extended steel bar into the stabilizing pipe 2, and the construction worker holds the extended steel bar. The operating tool clamps the first anti-slip part 9 to keep the threaded cylinder 1 stationary. Use another operating tool to clamp the rotating block 7 and rotate it, which will drive the threaded rod 8 to drive the threaded pipe 6 closer. During this process, the sliding rod 4 pushes the supporting piece 3 to move. After rotating the rotating block 7 multiple times, the two supporting pieces 3 come into contact with each other to form a circular tube shape, hold the extended steel bar between the two supporting pieces 3, and align the threaded part of the extended steel bar with the threaded part of the threaded cylinder 1. Use the operating tool to clamp the extended steel bar and rotate it again, and screw the threaded part of the extended steel bar into the threaded cylinder 1 to complete the installation of the extended steel bar.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
