Description

Technical Field

[0001] This invention relates to the field of rebar connection, and more specifically to a rebar connector. Background Technology

[0002] Ordinary straight thread sleeve connections for reinforcing bars require one end of the rebar to be screwed into the sleeve, which is not suitable for integral connections of upper and lower reinforcing cages. Existing technologies use a threaded sleeve connection process, where the rebars at both ends are respectively fitted into the intermediate nuts, and then connected by an outer sleeve. Since the sleeve and the intermediate nuts, as well as the intermediate nuts and the rebars, are all rigidly connected, the phase of the intermediate nuts must be consistent (the thread trajectory must be consistent) to ensure that the sleeve and the threads of the intermediate nuts on both sides engage. Alternatively, a split sleeve can be used, where the sleeve is cut in half along the axis and joined at the straight thread of the rebar, with both ends fixed by an outer nut. However, the problem of ensuring the phase of the straight threads of the rebars at both ends remains.

[0003] Accordingly, the present invention proposes a rebar connector to solve the above-mentioned problems. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a rebar connector, which, by setting a sliding sleeve that can rotate freely relative to one end, can adapt to any starting angle of the thread on the other end, ensuring effective engagement of the connecting threads.

An internal hexagonal groove is provided on the outer surface of the end head.

[0009] Furthermore, the second external thread passes through the first internal thread cavity and the first insertion channel from one side in sequence and is threadedly connected to the threaded sleeve, with the end abutting against the abutting step for limiting.

[0010] Furthermore, one end of the second reinforcing bar is thickened to form a connecting end, and the connecting end is provided with a third external thread.
