[0002] Rebar is the common name for hot-rolled ribbed steel bars. Rebar is an essential steel material for medium-sized and larger building components. There are two common classification methods for rebar: one is based on geometric shape, which is classified or typed according to the cross-sectional shape of the transverse ribs and the different spacing between the ribs, and rebar is divided into three grades; the other is based on comprehensive performance, which is divided into five types, usually with two longitudinal ribs and transverse ribs evenly distributed along the length.

DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example: A threaded steel joint sleeve, such as Figures 1-4 As shown, it includes a connecting sleeve body 1, a mounting cylinder 4, a rotating round block 5, an extrusion block 6, a limit frame 7 and a sliding rod 8. The inner wall of the connecting sleeve body 1 is provided with a thread groove adapted to the thread of the outer wall of the threaded steel bar. The head and tail ends of the connecting sleeve body 1 can be detachably connected with the mounting cylinder 4. The ends of the head and tail ends of the connecting sleeve body 1 are provided with round holes. The side where the mounting cylinder 4 is connected to the end of the connecting sleeve body 1 is provided with a vertical rod adapted to the round hole. The vertical rod and the round hole are interference fit. The mounting cylinder 4 is divided into two inner and outer circles. The inner ring of the mounting cylinder 4 is evenly spaced with through grooves 41. The inner ring of the mounting cylinder 4 is slidably provided with a sliding rod 8 near the through groove 41. The sliding rod 8 is connected to the limit frame 7. One end of the sliding rod 8 is fixedly connected to the limit frame 7, and the other end slides into the inner cavity of the inner ring of the mounting cylinder 4. The limit frame 7 is connected to the threaded steel bar. The cam 71 is provided with a stopper 71 at one end against which the outer wall of the steel is abutted, and the end of the stopper 71 away from the limit is a serrated structure, which is conducive to increasing the friction and stability between the stopper 71 and the outer wall of the threaded steel, thereby achieving the effect of effective abutment between the stopper 71 and the threaded steel. The top of the mounting cylinder 4 is rotatably provided with a rotating round block 5, and the bottom end of the rotating round block 5 is evenly spaced along its circumference with extrusion blocks 6. The number of extrusion blocks 6, limit frames 7 and through slots 41 is the same, and the extrusion block 6 slides along the annular groove between the inner and outer rings of the mounting cylinder 4 and is extruded and matched with the limit frame 7. The limit frame 7 is connected to the abutment block 71 on one side for a bevel setting. This setting facilitates the extrusion block 6 to move along the bevel to extrude the limit frame 7. The extrusion block 6 squeezes the limit frame 7 so that the limit frame 7 passes through the through slot 41 and abuts against the outer wall of the threaded steel connected to the connecting sleeve.

[0025] like Figure 4 As shown, the end of the sliding rod 8 away from the limit frame 7 is connected to an elastic member 9, and the end of the elastic member 9 away from the sliding rod 8 is fixedly connected to the inner cavity of the inner ring of the mounting tube 4. The function of the elastic member 9 is to reset the limit frame 7 when the extrusion block 6 no longer squeezes the limit frame 7, so that the extrusion block 6 is separated from the outer wall of the threaded steel bar. The elastic member 9 is a spring or a rubber member with elastic properties. As a preferred embodiment, the elastic member 9 in this embodiment is a spring. In its initial state, the limit frame 7 is in contact with the outer ring of the mounting tube 4.

[0026] like Figure 2As shown, nuts 2 for driving the connecting sleeve body 1 to rotate are symmetrically fixed on the connecting sleeve body 1. The nuts 2 are set as hexagonal nuts, and this setting matches the corresponding wrench. A rotating cylinder 3 for driving the connecting sleeve body 1 to rotate is fixed on the outer wall of the connecting sleeve body 1. The rotating cylinder 3 is set between the two symmetrical nuts 2.

[0027] During use, the mounting tube 4 is installed at the head and tail ends of the connecting sleeve body 1, and then, the nut 2 or the rotating tube 3 is driven by a tool to rotate to drive the connecting sleeve body 1 to rotate, so that the internal thread groove of the connecting sleeve body 1 cooperates with the external thread of the threaded steel to realize the effective connection between the connecting sleeve body 1 and the threaded steel; then, by rotating the rotating round block 5, the extrusion block 6 slides along the annular groove between the inner and outer circles of the mounting tube 4 and squeezes the limit frame 7, so that the limit frame 7 passes through the through groove 41 and abuts against the outer wall of the threaded steel connected to the connecting sleeve, thereby enhancing the stability of the connection between the connecting sleeve body 1 and the threaded steel.

[0028] like Figure 1 、 Figure 5 and Figure 6 As shown, a shielding tube 11 is sleeved on the outer wall of the connecting sleeve body 1, and the shielding tube 11 is arranged on the outside of the rotating cylinder 3. Four L-shaped limiting plates 1001 are evenly spaced along the circumference of the lower end of the shielding tube 11. A fixed cylinder 10 is provided on the outer wall of the connecting sleeve body 1. A positioning block 12 is fixedly connected to the fixed cylinder 10. A rectangular notch is provided on the positioning block 12 for the L-shaped limiting plate 1001 to be inserted to limit the L-shaped limiting plate 1001. After the positioning block 12 passes through the notch, the shielding tube 11 is rotated counterclockwise, and the shielding tube 11 drives the lower part of the positioning block 12 to be inserted into the L-shaped limiting plate 1 001 bottom, thereby realizing the function of installing the shielding tube 11 on the fixed tube 10, rotating the shielding tube 11 clockwise, the shielding tube 11 drives the blocking block 12 to rotate, and when the lower part of the blocking block 12 is away from the L-shaped limit plate 1001, the shielding tube 11 is pulled upward to lift the blocking block 12 out of the fixed tube 10, thereby realizing the separation of the shielding tube 11 and the fixed tube 10; a rubber ring 13 is provided on the inner wall of one end of the shielding tube 11 away from the L-shaped limit plate 1001, and the rubber ring 13 is used to close the gap between the shielding tube 11 and the connecting sleeve body 1, thereby further enhancing the sealing effect.

[0029] When the shielding tube 11 needs to be installed, the shielding tube 11 is sleeved on the outside of the connecting sleeve body 1, the positioning block 12 is inserted downward into the notch of the L-shaped limiting plate 1001, and then the shielding tube 11 is rotated counterclockwise, so that the lower part of the positioning block 12 is inserted into the bottom of the L-shaped limiting plate 1001, thereby effectively fixing the shielding tube 11 on the fixing tube 10, thereby providing anti-damage protection for the connecting sleeve body 1, thereby extending the service life of the connecting sleeve body 1.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
