[0008] Furthermore, the support frame includes: an inner ring and an outer ring, with a connecting plate provided below the inner ring;

[0009] The inner ring and the outer ring are connected by a connecting frame.

[0010] Furthermore, the inner support frame includes: a long arm beam and a short arm beam, and both ends of the long arm beam are respectively connected between the outer ring and the connecting frame;

[0011] The short arm beam is arranged between the long arm beams, and a triangle structure is formed between the short arm beam and the long arm beam.

[0012] Furthermore, the connecting frame includes: an outer frame, wherein a cross arm and a longitudinal beam are provided inside the outer frame;

[0013] Both ends of the long arm beam are connected to the outer frame and the outer ring.

[0014] Furthermore, a first pulley is provided on one side of the outer frame close to the outer ring.

[0015] Furthermore, a second pulley is provided on a side of the inner support frame close to the outer ring.

[0016] Furthermore, the first pulley and the second pulley are rollingly connected to the outer frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The support frame, inner support frame and connecting frame cooperate to form a stable frame structure, which provides reliable support for the retractable revolving door, and also strengthens the overall structural strength of the retractable revolving door, ensuring the reliable operation of the retractable revolving door.
