From d1, while the first guidance part 363c of the STATEMENT OF FEDERALLY SPONSORED 363 between the driver plate 364 and the swivel plate 361
Also it is driven by the driver plate 364 toward mobile first predetermined distance d 1 in the direction of the first axle L1, described second leads
Draw portion 363d and moves one second in advance from the expansion end 3618 toward the folding end 3619 along the arcuate socket 3617 simultaneously
Set a distance d2.Specifically, first predetermined distance d 1 is to be parallel to described lead with second predetermined distance d 2
The displacement of plate portion 361c and 3614 extending direction of orbit hole, and since the first guidance part 363c is led with described second
The portion 363d of drawing is mobile by axle center of the shaft 363b, therefore it is still necessary to close for the practical amount of movement of the first guidance part 363c
And calculate the displacement moved in the oval driving hole 364c along the front-rear direction D2, the second guidance part 363d
Practical amount of movement also must the displacement that moves in the driven hole 365c of the ellipse along the front-rear direction D2 of joint account.Institute
Stating the first predetermined distance d 1 and second predetermined distance d 2 is proportionate relationship, and second predetermined distance d 2 is greater than described the
One predetermined distance d 1, therefore to drive the driven seat 365 in succession past described in the casing 11 simultaneously by the second guidance part 363d
During mobile second predetermined distance d 2 in corresponding 32 direction of the transmission shaft, the joint surface 14 can be not only overcome
It is poor with the internal-and external diameter folded between the 112a of face, it not will receive on D1 in left and right directions during bending the coverboard 12
It pulls, and interlocks the linkage 3 with the skeleton structure 5 by the casing 11 and in the process of the casing 11 rotation
In keep identical distance between the coverboard 12, with can perseverance be supported in the coverboard 12.
Refering to Fig. 3 to Fig. 5 and Figure 26 to Figure 29, when the casing 11 turns to the folding position, the joint surface 14
Part positioned at the first casing 11a and the part positioned at the loading plate 13 are in back-to-back appearance, and the coverboard 12 is curved
It is converted into curved, and the permanent center that is supported and can be fixedly supported bendable screen by the skeleton structure 5.The connection unit
35 along the tube socket 31 361 surface curvature of the connecting plate portion 311 and the swivel plate, the synchronous piece 33 is far from the tube socket
31, it is separated out between the first outer side edges 3613 of the swivel plate 361 of each linkage unit 36 and the second outer side edges 364b of driver plate 364
First predetermined distance d 1 ', the link rod part 363a of the STATEMENT OF FEDERALLY SPONSORED 363 be posted by the fan groove 3615 wherein the other half
Diameter side 3615b and the second guidance part 363d are located at the folding end 3619 of the arcuate socket 3617.
Referring again to Fig. 6 and Fig. 7, due to the loading plate 13 by the bendable screen and the first casing 11a,
The coverboard 12 is connected and relatively fixed, and the first casing 11a, the coverboard 12 pass through institute with the second casing 11b again
State that linkage 3 is relatively fixed, therefore in the normal rotational of the casing 11, the loading plate 13 and second machine
Shell 11b is will not to generate relative movement, and the buffer stopper 21 is maintained at the normality end 1141 of the dashpot 114d.No
It crosses, when the linkage 3 is because of manufacturing tolerance, artificial assembly error or other flaws, may result in 11 turns of the casing
Amount of movement is insufficient and can not be successfully mobile second predetermined distance d 2 in dynamic process (see Figure 25).Due to described bendable glimmering
Curtain one end is permanently connected the first casing 11a, and it is insufficient to occur amount of movement during the casing 11 rotation, it is described can
Can the in succession loading plate 13, the buffer stopper 21, the linked block 22 and the second casing 11b of the formula screen other end is scratched to produce
Raw relative movement, avoids the bendable screen from being combined by the casing 11 and pulls damage.During relative movement, institute
It states buffer stopper 21 to relatively move from the normality end 1141 toward the direction of the buffering end 1142, the linked block 22 is toward far
Direction relative movement from the limit hole 114f.The elastic component 23 can pass through simultaneously the reaction force of the elastic dilatation power
So that the second casing 11b is moved to second predetermined distance d 2, the buffer stopper 21 is made to be moved back to the normality end
1141, the linked block 22 is moved back to the limit hole 114f, restores the normal position to the casing 11 at the folding position
It sets.In the state sample implementation of variation, the second casing 11b and the screen protective module 2 are also not necessarily limited to be mounted on this implementation
The outer folding screen apparatus 100 of example can also mutually assemble collocation with the hinge, turning gear and shell of other aspects and use.
In conclusion the outer folding screen apparatus 100 of the utility model on the transmission shaft 32 by designing synchronous bar portion
322 match with the synchronous piece 33, and making the transmission shaft 32 is to rotate synchronously when rotating, and increase when linkage 3 rotates
Stability pivot two casings 11 can not with different angle, avoids pullling screen and causes to damage;In addition, the casing 11 from
Position is shakeout toward during the rotation of folding position, since swivel plate 361 is that axle center rotates with corresponding transmission shaft 32, and is passed
Movable plate 364 is to be rotated using the first axle L1 for being located at 32 top of transmission shaft as axle center, makes both driver plate 364 and swivel plate 361
It is poor to generate internal-and external diameter, that is, driver plate 364 can be relative to mobile one first predetermined distance d 1 of swivel plate 361, and passes through sector
The design of slot 3615 and driving member enables the second guidance part 363d of driving member to move one and is greater than first predetermined distance d 1
Second predetermined distance d 2 drives toward the movement of corresponding 32 direction of transmission shaft described in casing 11, and compensation internal-and external diameter difference may cause
The risk of screen damage, therefore the purpose of the utility model can be reached really.
As described above, only the embodiments of the present invention, when the utility model implementation cannot be limited with this
Range, i.e., it is all according to simple equivalent changes and modifications made by the utility model claims book and description, all still belong to
The scope of the utility model.
