[0028] Referring to Figures 1 to 5 .

[0029] The steel sleeve assembly for reinforcing steel bar connection is suitable for the mutual connection of the to-be-connected reinforcing steel bar one 1 and the to-be-connected reinforcing steel bar two 2, and comprises:

[0030] The steel sleeve body 3 is used for inserting the to-be-connected reinforcing steel bar one 1 and the to-be-connected reinforcing steel bar two 2 from both ends, and a first external thread 301 is formed on the outer wall of both ends of the steel sleeve body 3;

[0031] Two locking sleeves 4 are used for being sleeved on both ends of the steel sleeve body 3, and an internal thread is formed on the inner wall of the two locking sleeves 4, a second external thread 122 is formed on the to-be-connected reinforcing steel bar one 1 and the to-be-connected reinforcing steel bar two 2, and the locking sleeve 4 is threadedly connected with the steel sleeve body 3 and the to-be-connected reinforcing steel bar one 1 or the to-be-connected reinforcing steel bar two 2.

[0032] In use, the to-be-connected reinforcing steel bar one and the to-be-connected reinforcing steel bar two are inserted into both ends of the steel sleeve body through the corresponding locking sleeves, then the locking sleeves are screwed, the locking sleeves are threadedly connected between the first external thread and the second external thread, the stable fixation of the steel sleeve assembly, the to-be-connected reinforcing steel bar one and the to-be-connected reinforcing steel bar two can be realized, and the loosening between the components is reduced.

[0033] In an embodiment, a supporting boss 121 is arranged on the to-be-connected reinforcing steel bar one 1 and the to-be-connected reinforcing steel bar two 2, and the second external thread 122 is formed on the outer circumferential surface of the supporting boss 121. In this way, when connected, the supporting boss can abut against the steel sleeve body, so that the thread connection is more firm.

[0034] In an embodiment, a limiting boss 302 is arranged on the inner wall of the middle part of the steel sleeve body 3. The limiting boss is used for limiting the to-be-connected reinforcing steel bar one and the to-be-connected reinforcing steel bar two, so that the connection lengths of the two reinforcing steels are balanced.

[0035] In an embodiment, a self-locking structure 5 for locking the to-be-connected reinforcing steel bar one 1 or the to-be-connected reinforcing steel bar two 2 is arranged on both sides of the limiting boss 302 in the steel sleeve body 3. The self-locking structure is used for further strengthening the connection of the reinforcing steel.

[0036] In an embodiment, the self-locking structure 5 comprises a plurality of self-locking clamping plates 501 arranged in a ring array along the circumference of the steel sleeve body 3, the outer end of the self-locking clamping plate 501 is hinged on the steel sleeve body 3, and the inner end of the self-locking clamping plate 501 is provided with anti-disengagement clamping teeth 502 facing the first steel bar 1 or the second steel bar 2 to be connected.
