Specific embodiment
Referring to figs. 1 to Fig. 4, the utility model is a kind of hand-operated curtain system, including Limit screw 1, the Limit screw 1
One end is connected with manual backup, and the other end is connected with transmission shaft 3, and manual backup includes that case 21 and connection is drawn to draw 21 input terminal of case
Chain rope 22, the output end for drawing case 21 connect Limit screw 1, and chain rope 22 drops to curtain bottom vertically, convenient for manual operation.
Fixed swivel nut 4 is threaded on the Limit screw 1, the transmission shaft 3 is equipped at least two sections of ropes 6, the limit
Position screw rod 1 screw pitch otherwise be less than rope 6 diameter, guarantee rope 6 promoted or transfer when, rope 6 will not occur
The case where overlapping, each described 6 one end of rope is fixed by transmission shaft 3, the rotation of Limit screw 1 make transmission shaft 3 promoted or under
Put rope 6.
This hand-operated curtain system, including Limit screw 1, one end of Limit screw 1 are connected with manual backup, other end connection
Transmission shaft 3 is threaded with fixed swivel nut 4 on Limit screw 1, the rope 6 of folding and unfolding curtain is arranged on transmission shaft 3.Pass through
Driving to manual backup, Limit screw 1 rotate, and transmission shaft 3 is driven equably to promote or decline rope 6, realize rope 6
Uniform folding and unfolding, and the screw pitch of Limit screw 1 is greater than the diameter of rope 6, it is therefore prevented that and rope 6 is mentioned in promotion or decline
Drawstring 6 overlaps on transmission shaft 3, occurs stirring line situation.
As the utility model preferred embodiment, the screw pitch of Limit screw 1 is not less than the diameter of rope 6.In this way
When setting can make 6 folding and unfolding of rope, guarantee does not interfere each other, there is a situation where stirring line, makes curtain that stuck feelings occur
Condition is reduced, and curtain operation is more flexible.Further, it is more preferably selected as one kind, the screw pitch of Limit screw 1 is equal to rope 6
Diameter.
Referring to Fig. 4, as the utility model preferred embodiment, manual backup includes that case 21 and connection is drawn to draw case 21 defeated
Enter the chain rope 22 at end, the output end for drawing case 21 connects Limit screw 1.Chain rope 22 extends vertically downward to the bottom end of curtain,
