Referring to fig. 1-3, the utility model discloses an one-way folding hinge, include: the rotating part and the connecting

4;

the rotating part comprises a

1, an adjusting

2 and a

3;

the rotating

1 is a flat shaft, and two planes are symmetrically arranged on the basis of a round shaft;

referring to fig. 4, two special-shaped holes are symmetrically arranged in the adjusting block, each special-shaped hole comprises a waist-

21 matched with the cross section of the rotating shaft, the waist-

21 rotate to one side by taking the center as the center of the circle to form an

22 on the adjusting

2, the rotating

1 penetrates through the waist-

21, and the rotating

1 rotates in one direction towards the adjusting

22;

after the rotating

1 penetrates into the special-shaped hole, two planes of the rotating

1 are attached to two straight edges of the waist-

21, and the rotating

1 rotates to drive the adjusting

2 to rotate; the adjusting

22 are formed by cutting off straight edges of the waist-

21 according to a certain angle, the two adjusting

22 are symmetrical along the center of the waist-

21, and two planes are attached to the two edges of the adjusting

22 after the rotating

1 rotates; the special-shaped hole formed by combining the waist-

21 and the adjusting

22 in the whole adjusting

2 is equivalent to the special-shaped hole formed by rotating the whole waist-

21 around the center by a certain angle, so that the rotating

1 can only be adjusted in a single direction according to the angle. Because the adjusting

22 are symmetrically arranged in the center of the kidney-shaped

21, when the

1 rotates reversely in the kidney-shaped

21, two planes of the

1 are attached to the planes of the kidney-shaped

21 and return to the initial state, and the whole

1 cannot rotate reversely.

Referring to fig. 3, the transmission blocks 3 are sleeved on the

1, the transmission blocks 3 and the

1 rotate synchronously, and the

31 which are meshed with each other are arranged between two adjacent transmission blocks 3; one of the

1 rotates to drive the other

1 to rotate reversely through the mutually meshed transmission blocks 3.

The

3 is tightly connected with the

1, and the

1 rotates to drive the

3 to synchronously rotate; the surface of the

3 is provided with

31, and the

31 of two adjacent transmission blocks 3 are meshed to realize transmission; it should be noted here that the engaging

31 drive the two

3 to rotate in opposite directions, so that the two adjacent profiled holes in the

2 are symmetrical to each other, that is, the positions of the

22 in the two adjacent profiled holes are opposite, and the adjacent

1 are driven to rotate in opposite directions by a certain angle.

Connect through connecting

4 between a plurality of rotating parts and form the hinge, 4 covers of connecting piece are established on the

1 of two adjacent rotating parts, intermeshing between the

3 of two adjacent transmission portions.

It is conceivable that a plurality of rotating portions are connected by a connecting

4 to form a hinge structure, and two adjacent rotating portions are rotated by a driving

3. The single rotating part rotates in a single direction for a certain angle, after the transmission parts are connected into a chain, the single-direction bending of the whole hinge can be realized, and the folding and the looping of the whole hinge can be realized by changing the inclination degree of the adjusting

22.

Further, referring to fig. 5, a first connecting

5 and a second connecting

6 are respectively disposed at two ends of the hinge, and the first connecting

5 and the second connecting

6 are sleeved on the

1. The same flexible part can be connected through the first connecting

5 and the second connecting

6, and the one-way folding of the flexible part can be realized by applying pressure to the first connecting

5 or the second connecting

6.

Further, the first connecting

5 is provided with a first connecting

51, and the shape of the first connecting

51 is matched with the shape of the cross section of the

1; the second connecting

6 is provided with a

61, and the second connecting

6 is rotatably connected with the

1 through the

61.

Specifically, if the whole hinge is to perform bending rotation, the

1 at the end of the hinge must be rotated, and the first connecting

5 and the second connecting

6 are mounted at the end of the hinge. Therefore, it is necessary to ensure that the first connecting

5 and the second connecting

6 rotate synchronously with the

1, and here, the first connecting

51 in the first connecting

5 is matched with the

1 and can rotate synchronously with the

1. One end of the whole hinge rotates to drive the whole hinge to bend, and one end of the first connecting

5 is set as an end point to drive one end of the second connecting

6 to bend. Therefore, the second connecting

32 and the

1 do not need to rotate synchronously, and can be directly hinged.

Furthermore, as the preferred scheme of the utility model, the connecting

4 is clamped between the adjusting

2 and the

3, and the mounting positions of the first connecting

5 and the second connecting

6 are flush with the mounting position of the connecting

4; because first connecting

5 and second connecting

6 are at the both ends of whole hinge, install the position that can not only make both

4 vacate at the position of connecting

4 complete, set up simultaneously and can make the even atress of

1 in the centre of

1.

Furthermore, in order to ensure the synchronism of the

3 and the

1, a second connecting

32 matched with the

1 is formed in the

3, and the shape of the second connecting

32 is matched with the shape of the cross section of the

1. Preferably, the shape of the

32 may be a kidney-shaped

21, which ensures that two planes of the

1 are attached to the

32 to drive the

1 to rotate.

Further, referring to fig. 6, a

41 is formed in the connecting

4 to be engaged with the

1, wherein the connecting

4 serves to connect the rotary parts and form a whole chain structure without rotating synchronously with the

1.

Further, referring to fig. 3, in order to limit the axial movement of the adjusting

2, the

3 and the connecting

4 on the

1, a clamping table 11 is arranged at one end of the

1, a

7 is arranged at the other end of the

1, the clamping table 11 is attached to one side of the adjusting

2, and the

7 is attached to one side of the

3. The whole hinge is prevented from falling off the adjusting

2, the

3 and the connecting

4 in the rotating process.

Further, referring to fig. 7, the

7 includes a locking

71, the locking

71 is sleeved on the

1, and a

72 is arranged between the locking

71 and the

3; the side of the

1, which is matched with the locking

71, is provided with an

12.

Specifically, the locking

71 is matched with the

12 on the

1, and the adjusting

2, the

3 and the connecting

4 are clamped on the

1 by rotating the locking

71; meanwhile, in order to prevent the locking

71 from directly contacting with the transmission member during rotation, a

72 is installed between the locking

71 and the

3 to prevent damage to the surface of the transmission member.

Referring to fig. 8-9, the utility model discloses because self can only be according to certain angle unidirectional rotation, consequently can use the technical field of folding screen cell-phone, install folding cell-phone screen on first connecting

5 and second connecting

6, can realize the one-way folding of screen, prevent that the screen from receiving reverse external force and leading to the screen to damage. The watch can be applied to the field of watches, and as a watchband, the watch can only rotate in one direction and has the foolproof effect.

To sum up, the utility model discloses an one-way folding hinge and folding screen mobile terminal, through the restriction of two sets of abnormal shape

1 that set up in adjusting

2, wear to establish the

1 of abnormal shape can only be according to the certain angle of the one-way rotation of shape in abnormal shape hole,

1 rotates and drives the certain angle of

1 antiport through

3 and forms crooked, a plurality of drive blocks 3 drive a plurality of

1 and rotate the same angle, thereby make whole hinge formation crooked, whole chain rotation direction is the same with the crooked direction of the adjacent two

1 of tip, the crooked direction of whole hinge has been decided to the direction of

1. The utility model discloses can realize folding screen cell-phone one-way folding, receive opposite power and can not buckle, the protection screen does not receive the damage.
