Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Spring rolling curtain device as depicted in figs. 1 and 2, including first support 1, the second support corresponding with first support 1
2, two ends are separately fixed at the spool 3 in first support and second support, are arranged on the spring rod 4 in spool, are set in spring
The outer limit spring 5 being located in spool of rod 4, the fixing spring tail plug 8 in spool with limit spring 5.Described first
It is provided with the governing mechanism of tension that the tension force to limit spring is adjusted, described limit spring passes through this tension adjustment inside frame
Mechanism is connected with first support.
In the present embodiment, described governing mechanism of tension includes:
It is arranged on the tension adjustment core 6 inside first support, this tension adjustment core 6 outer wall is provided with circumferentially disposed fourth gear card
