Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples, but not as any limitation of the invention.
Fig. 1 is the structural front view of the present invention, and Fig. 2 is the structure top view of the present invention, referring to the drawings as can be seen that this hair
Bright fast opening blind is mainly made of high neck 1 and cover board 2, is welded on cover board 2 and is beaten round-meshed cover board boss 11.High neck 1
On be fixed with upper support frame component 3 and lower bracing frame component 4.Right end and upper support frame component 3 in 5 one end of rocker arm assembly, that is, Fig. 1
It is connected with lower bracing frame component 4 by mandrel 6, left upper part is using adjusting screw rod 10 and thrust force aligning rolling in the other end, that is, Fig. 1
Sub- bearing is connected with upper rotating assembly 7, and lower part is connected using cylinder roller bearing with lower rotary shaft component 8, and upper rotating assembly 7 is under
Rotating assembly 8 is bolted respectively with the cover board lug 9 on cover board 2 using bearing is simultaneous.Adjusting screw rod 10 is furnished with adjusting nut 12.
Rocker arm assembly 5 drives cover board 2 that can both have been rotated together around mandrel 6 during implementation, also can around self-aligning thrust roller bearing and
It is rotated at cylinder roller bearing and the high and low position of cover board 2 can be adjusted by adjusting screw rod 10.So make cover board 2 open freely and
It can be with 1 accurate fit of high neck.
The lock ring that cover board 2 and high neck 1 are locked or are unclamped can be welded by being provided on cover board 2 and the circumferential periphery of high neck 1
Part 13,4 guide lugs of circumference uniform distribution on cover board 2 when lock ring weldment 13 unclamps, and cover board 2 is opened, pass through guide lugs card
Firmly lock ring weldment 13 so that lock ring weldment 13 will not drop out, and can smoothly return original when cover board 2 is closed.Ensure opening square
Just it is, laborsaving.
In the notch of lock ring weldment 13 insert block groupware knot is used equipped with release mechanism component 14, release mechanism component 14
Structure, release mechanism component 14 are fixed on using safe stud 15 on cover board 2.Safe stud 15 both can release, when the safe spiral shell of turn
During column 15, its sealing between cover board 2 starts to loosen, and overbottom pressure is discharged along gas vent.Also can ensure in release mechanism component 14
Insert block groupware will not pop up due to stress.Lock ring weldment 13 is connected with cover board 2 using linkage 16.In linkage 16
