Extend along the length direction of bottom plate 25 and corresponding to the upper guide groove 23 of upper mounted plate 21, lower fixed hole 28 corresponds to upper solid
The upper fixing hole 24 of fixed board 21.
First drive 30 has that 2 first transmission fluted discs 31 and one are connected between the 2 first transmissions fluted disc 31
One power axle 32, assembling when by the first power axle 32 be sheathed on fixed seat 20 wherein two upper and lower fixed columns 22,
26, after assembly is completed, 2 first drive 30 first transmission fluted disc 31 can each other bridle joint together, make this 2 first
Drive 30 can synchronous axial system.
The two ends of wind spring 40 connect the first power axle 32 of the first drive 30 respectively so that wind spring 40 can by this 2
The rotation of one drive 30 and the first power axle 32 for being wound in one of them the first drive 30.
Second drive 50 has that 2 second transmission fluted discs 51 and one are connected between the 2 second transmissions fluted disc 51
Two power axles 52, assembling when by the second power axle 52 be sheathed on fixed seat 20 other two upper and lower fixed columns 22,
26, after assembly is completed, the second transmission fluted disc 51 meeting bridle joint of the second drive 50 is in the first transmission of the first drive 30
Fluted disc 31 so that first, second drive 30,50 being capable of synchronous axial system.
The second power axle 52 of the second drive 50 is fixed in one end of transmission rope 60, and the other end of transmission rope 60 is passed
Curtain 16 and it is fixed on underbeam 14.
Resistance unit 70 has two movable axis 71, two tension springs 72, two stop parts 73, and two resistance wheels 74, such as Fig. 2
Shown in Fig. 4.Top, the bottom two ends of movable axis 71 have a guide block 75 respectively, and movable axis 71 is embedded at fixed seat 20 by guide block 75
Upper and lower guide groove 23,27 in, because the length of guide block 75 is less than the length of upper and lower guide groove 23,27 so that movable axis 71 can edge
The upper and lower guide groove 23,27 for fixed seat 20 is moved；Two tension spring 72 connect respectively two movable axis 71 guide block 75 it
Between, movable axis 71 to be pulled toward the direction of the second drive 50；Stop part 73 by taking the body of rod as an example, in assembling, is kept off herein
Top, the bottom two ends of stop member 73 are plugged respectively to be fixed in the upper and lower fixing hole 24,28 of fixed seat 20, after assembly is completed, gear
Stop member 73 can be located between the second drive 50 and movable axis 71；Resistance wheel 74 have two resistance fluted discs 76 and one be connected to this two
Resistance wheel shaft 77 between resistance fluted disc 76, resistance wheel 74 is sheathed on movable axis 71 by resistance wheel shaft 77 in assembling and is transmitted
Rope 60 surround a circle so that on the one hand resistance wheel 74 can make resistance fluted disc 76 depart from stop part by the pulling force of transmission rope 60
73, on the other hand resistance fluted disc 76 can be made to be connected in stop part the elastic-restoring force of movable axis 71 by tension spring 72 again
73。
When curtain 16 to be deployed, as shown in figure 5, exerting a force the pulled down of underbeam 14 first, make each transmission rope 60 by under
Beam 14 is stretched, and the second drive 50 can be driven to rotate during transmission rope 60 is stretched, then the meeting of the second drive 50
Drive the first drive 30 to rotate again, wind spring 40 is furled from one of them first drive 30 to another the first drive
30 and the elastic-restoring force of accumulation itself, on the other hand, during transmission rope 60 is stretched can while pull resistance wheel 74,
Resistance wheel 74 is set to drive movable axis 71 to be moved toward the direction away from the second drive 50, once the guide block 75 of movable axis 71 is resisted against
During the outer end of the upper and lower guide groove 23,27 of fixed seat 20, as shown in figure 3, resistance wheel 74 resistance fluted disc 76 can and stop part 73 it
Between it is disconnected from each other, resistance wheel 74 is transmitted rope and 60 pull and rotated around movable axis 71, while tension spring 72 also can
Stretched and the elastic-restoring force of accumulation itself by the guide block 75 of movable axis 71, after curtain 16 is expanded into a precalculated position
The pulling force of underbeam 14 is bestowed in release, and now tension spring 72 can pull movable axis 71 by the elastic-restoring force of itself, make resistance wheel
74 move with movable axis 71 towards the direction of the second drive 50, once the guide block 75 of movable axis 71 is resisted against fixed seat 20
During the inner of upper and lower guide groove 23,27, as shown in figure 4, the resistance fluted disc 76 of resistance wheel 74 can be connected in stop part 73, such one
Come, resistance wheel 74 can stop operating, transmission rope 60 at this time can utilize produced frictional resistance between resistance wheel 74
And the state of standing balance is presented between the elastic-restoring force of wind spring 40, curtain 16 is stably held in deployed condition.
When curtain 16 to be folded, underbeam 14 is up promoted as shown in fig. 6, exerting a force first, transmission rope 60 is become pine
The state of relaxation is to reduce the frictional resistance between resistance wheel 74, and the elastic-restoring force of wind spring 40 at this time can be with user
Thrust force 2 first drive 30 simultaneously to rotate backward, can band again during the first drive 30 is rotated backward
Dynamic second drive 50 is rotated, and makes the second drive 50 start to furl transmission rope 60, the mistake furled in transmission rope 60
Cheng Zhong, by resistance wheel 74 can be by the mutual clamping between stop part 73 to pulling force that movable axis 71 is bestowed of tension spring 72
Together, that is, resistance wheel 74 can be maintained at the state stopped operating.Discharged again after curtain 16 is being folded completely under bestowing
The thrust of beam 14, makes transmission rope 60 again tightly around in resistance wheel 74, now the elastic-restoring force of wind spring 40 is with transmission rope 60 and resistance
The state of standing balance will be presented between frictional resistance between wheels 74 once again, is stably held in curtain 16 and folds shape
State.
In summary, curtain detent mechanism 18 of the invention in structure mainly by for furling the of transmission rope 60
First, the second drive 30,50 and for controlling the resistance wheel 74 of the start of transmission rope 60 to combine, compared with known technology it
Under can effectively simplify structure and reduction assembling degree of difficulty, be in addition to utilize institute between transmission rope 60 and resistance wheel 74 in operation
Clamping relation between the frictional resistance and resistance wheel 74 and stop part 73 of generation and good locating effect is provided curtain 16,
Increase ease of use is reached effectively to solve the problems, such as the rise of curtain 16 after deployment and the sagging problem when folding
Purpose.
