Preferably, the inner end of the swinging rod is connected with the central shaft through an adapter plate.

Preferably, a spacer bush is arranged between the adapter plates. The spacer bush is of a two-section structure formed by a spacer bush and a sleeve, the spacer bush is of a flat outer diameter and is used for separating the upper adapter plate and the lower adapter plate, the sleeve outer diameter is smaller, the adapter plate is sleeved on the sleeve, and the spacer bush is beneficial to smooth rotation of the adapter plate.

Preferably, the spacer material is tin bronze.

Preferably, a fixing cap is arranged at the lower end of the central shaft. The fixing cap can be used for decoration and also used for mounting and dismounting the adapter plate and the spacer bush.

Preferably, the section of the annular track is a C-shaped steel bend circle which is downwards opened and inwards bent, and the running change gear comprises 4 pulleys.

Preferably, the annular ring beam side wall is provided with an annular shading cornice. There is the clearance between flexible projection curtain outer lane and the annular ring roof beam lateral wall, and the shading eaves corridor can cover the clearance and avoid external influence.

The utility model has the advantages that: the folding curtain disclosed by the utility model is simple in integral structure and convenient to install, can be automatically controlled to realize horizontal folding and unfolding, meets the needs of a performance, and improves the experience of audience and the performance applicability of a dome building place.
