In one embodiment, when the rotation direction of the hinge coincides with the winding direction of the connection wire, the tension sheet moves in the axial direction, and the tension spring supporting the tension sheet is compressed.
In one embodiment, when the rotation direction of the hinge is opposite to the winding direction of the connection line, the tension sheet moves away from the axis, and the tension spring supporting the tension sheet expands.
In one embodiment, when the opening and closing angle of the hinge is adjusted, the tensioning piece and the fixing piece are independently rotated, the connecting wire wound on the tensioning piece is pulled out from the movable end connecting terminal, the connecting wire wound on the fixing piece is pulled out from the fixed end connecting terminal, and the lengths of the connecting wires at the two sides of the fixed end connecting lug and the movable end connecting lug are adjusted according to the opening and closing angle.
In one embodiment, the length of the connecting wire at two sides of the fixed end connecting lug and the movable end connecting lug is proportional to the opening and closing angle.
In one embodiment, the device further comprises a tensioning piece adjusting rod, wherein the tensioning piece adjusting rod is used for pushing the tensioning piece adjusting rod to enable the tensioning piece to rotate independently from the rotating shaft, and the position of the movable end connecting lug is adjusted.
In one embodiment, the tensioning sheet adjusting rod and the inside of the shell are provided with a sliding groove and a positioning groove, the sliding groove is used for supporting the connecting shaft of the tensioning sheet and the tensioning spring to slide in the sliding groove, and the positioning groove is used for limiting the position of the connecting shaft.

In one embodiment, the movable end adjustment lever has a square shaped member at an end thereof for mating with the hinge fixed end and the hinge movable end to allow the hinge fixed end and the hinge movable end to rotate synchronously.
The rotatable connection is described in one embodiment.
The fixed end adjusting rod and the movable end adjusting rod are arranged in the rotating shaft, and when the hinge is in a normal working state, the fixed end and the movable end can freely rotate and cannot pull a cable connected inside;
the hinge can carry out the regulation of angle that opens and shuts, and during the regulation mode, adjust the angle that opens and shuts of hinge through adjusting movable end regulation pole and stiff end regulation pole, but the rotatable coupling structure that this application provided can adjust as required, need not the customization. The internal concrete structure and principle are as follows:
as shown in fig. 2, the connecting wire penetrates from the fixed end, winds a certain number of turns on the fixed sheet, sequentially penetrates through the fixed end connecting lug and the movable end connecting lug, winds a certain number of turns on the tensioning sheet, finally penetrates out from the movable end, and the tensioning sheet is in a pretensioned state;
when the hinge rotates, when the rotation direction is consistent with the winding direction (for example, the movable end in the direction shown in fig. 2 rotates clockwise), the tensioning sheet approaches to the axle center, the tensioning spring supporting the tensioning sheet is compressed, otherwise, the tensioning sheet moves in the direction away from the axle center, and the spring supporting the tensioning sheet is relaxed.
Therefore, when the hinge rotates in a rotatable angle, the inner cable is always in a tensioning state, and when the hinge rotates in a winding direction, the tensioning piece is compressed, the diameter of a tensioning area is reduced, the winding number of the cable is increased, so that the cable is kept in a tensioning state and cannot be pulled; on the contrary, when the winding direction is reversely rotated, the tensioning sheet is relaxed, the diameter of the tensioning area is increased, the winding number of the cable is reduced, and the cable is kept in a tensioning state.
Fig. 3 shows a structural diagram of the inside of the rotating shaft, and in summary, the rotatable connection structure provided in the application can keep the cable in a tensioned state when the hinge rotates, and the cable cannot be torn.
The adjustable angle range of the hinge is adjusted through the ratio of the turns wound on the tensioning sheet to the turns wound on the fixing sheet, and particularly, the diameter of the reduced tensioning area is the same, and the number of turns wound on the tensioning sheet is more, so that the adjustable range is larger; conversely, the fewer turns wound on the tension sheet, the smaller the adjustable range.
The process and principle for adjusting the opening and closing angle of the hinge are as follows:
in the normal working process of the hinge, the tensioning area and the fixing area synchronously rotate, when the opening and closing angle of the hinge is adjusted, the tensioning area and the fixing area independently rotate, a cable wound on the tensioning sheet is pulled out from the movable end through control, a cable wound on the fixing sheet is pulled out from the fixed end, the lengths of the fixed end connecting lug and the two side cables of the movable end connecting lug are adjusted according to the opening and closing angle, if the opening and closing angle is needed to be larger, the length of the cable outside the movable end connecting lug is longer, otherwise, the length of the cable outside the fixed end connecting lug is shorter if the opening and closing angle is needed to be smaller, and correspondingly, the length of the cable outside the movable end connecting lug is wound with more turns on the tensioning sheet.
As shown in fig. 4, pushing the tensioning sheet adjusting rod can enable the tensioning sheet to rotate independently with the inner rotating shaft, so that the position of the movable end connecting lug can be adjusted, the tensioning sheet adjusting rod and the inner portion of the shell are provided with a sliding groove and a positioning groove, the connecting shaft and the spring for supporting the tensioning sheet slide in the sliding groove, the positioning groove can limit the position of the connecting shaft, the positioning shaft is fixedly connected with the tensioning sheet, the locking spring can keep the clamping force of the positioning groove, pushing the tensioning sheet adjusting rod enables the two portions of the positioning groove to be separated, the positioning effect is lost, at the moment, the tensioning sheet and the inner rotating shaft independently rotate, and the positioning effect is recovered after the tensioning sheet adjusting rod is reset.
As shown in fig. 5, in the normal working process of the hinge, the end part of the movable end adjusting rod is square, and the square part is matched with the fixed end and the movable end simultaneously, so that the fixed end and the movable end synchronously rotate, and the square part in the middle of the fixed end adjusting rod is matched with the round part in the fixed end, so that torque can not be transmitted.
The opening and closing angle is adjusted by the following steps:
(1) Pushing the fixed end adjusting rod, compressing the adjusting spring to enable the square section in the middle of the fixed end adjusting rod to be matched with the square hole in the fixed end, and rotating the fixed end adjusting rod can control the fixed end to rotate at the moment;
(2) Then the movable end adjusting rod is pulled back, so that the direction section of the end part of the movable end adjusting rod is separated from the fixed end, at the moment, the movable end can be independently rotated by rotating the movable end adjusting rod, and the fixed end can be independently rotated by rotating the fixed end adjusting rod;
(3) The fixed end and the movable end are rotated respectively to pull out the cable;
(4) The length of the two side cables of the fixed end connecting lug and the movable end connecting lug is adjusted according to the required opening and closing angle;
(5) The cable is rewound through the fixed end adjusting rod and the movable end adjusting rod, and the adjusting rod is reset.
