Conjunction portion matches with snap fit portion；
Upper limit ring and lower limit ring are additionally provided with described support bar, the position of upper limit ring causes sliding block to push up upwards
During upper limit ring, the lower surface to curtain hanging hook is pushed up in the top end face of curtain storage bucket just；The position of lower limit ring to slide
When lower limit ring is arrived on the downward top of block, the curtain being fully deployed can be articulated on hanging groove just by hanging wire.
Described holding section and snap fit portion is symmetrically arranged with two, and no matter curtain stores bucket clockwise or counterclockwise
Rotation, curtain storage bucket can be engaged on curtain hanging hook.
The application method of spacing projection screen storage device up and down, including a storage step and an expansion use step
Suddenly：
（1）Storage step includes following sub-step：
S11：Lifting hanging wire upwards, makes hanging wire depart from hanging groove, and curtain collapses into curtain storage bucket automatically；
S12：Unscrew clamping screw, lifting sliding block is tightened clamping screw and consolidated until sliding block top untill upper limit ring upwards
It is fixed；
S13：Around holding section of the connecting shaft rotating curtain storage bucket to its end on curtain hanging hook；
S14：The end of curtain storage bucket is firmly pressed, holding section is sticked into snap fit portion；
S15：Pack up leg and complete storage；
（2）Expansion includes following sub-step using step：
S21：Leg is opened, support is integrally placed on smooth ground；
S22：End and the curtain hanging hook of curtain storage bucket are firmly separated, holding section is deviate from from snap fit portion；
S23：It is horizontal to it that bucket is stored around connecting shaft rotating curtain；
S24：Unscrew clamping screw, the position of curtain storage bucket is adjusted downwards by sliding block, up to sliding block top to lower limit
Untill ring, tighten clamping screw and fix；
S25：Hanging wire is lifted, curtain is drawn to from curtain storage bucket and is fully deployed, hanging wire is suspended to curtain hanging hook

The beneficial effects of the invention are as follows：
（1）Storage bucket is arranged on support bar by rotary shaft, storage can be achieved in vertical place of storage bucket rotation, receives
Curtain is pulled out after bucket of receiving rotation is horizontal to come into operation, curtain and support can whole Transporting, storage, convenient transportation, storage center
Take up space small.
（2）During storage, storage bucket can be achieved in the snap fit portion that the holding section on curtain hanging hook sticks into storage bucket end
Fixation, be not easy to swing, good fixing effect, curtain hanging hook here is provided simultaneously with two effects, and one is fixed in storage
Bucket is stored, another effect is to hang curtain when in use, ingenious in design, eliminates individually storage bucket fixed mechanism, structure
Simply.
（3）During storage, sliding block slide into upwards upper limit ring position represent holding section on curtain hanging hook with storage
The snap fit portion alignment of bucket end, firmly matches somebody with somebody holding section press-in engaging when rotation storage bucket to its end is close to curtain hanging hook
Storage can be achieved in conjunction portion, storage is more convenient；Expansion is in use, sliding block represents receipts to the position for slipping down to lower limit ring
Bucket of receiving has arrived correct position, then down hanging wire just can't reach groove, up can not be fully deployed curtain, lower limit ring again
Design make it that the use of curtain is more convenient.
（4）Holding section and snap fit portion are symmetrically arranged with two, and no matter curtain storage bucket revolves clockwise or counterclockwise
Turn, can realize that engaging is stored, use is more flexible.
