Abstract
The invention discloses a multilayer constant-torque torsion spring device. An output constant torque is used for unfolding a hinge. The multilayer constant-torque torsion spring device comprises a fixing plate and a winding wheel, wherein a left hole and a right hole are respectively formed in the two sides of the fixing plate; a cylinder pin is inserted into the left hole; a cylinder shaft arranged at the center of the winding wheel is inserted into the right hole; the front side of the winding wheel is a large semicircle; a sleeve rod is fixed on the cylinder shaft of the winding wheel; and one side of a multilayer constant-torque torsion spring is rolled into a circular ring and is sleeved on the cylinder pin while the other side is wound on the winding wheel and the top end is fixed at the top of the winding wheel. When the multilayer constant-torque torsion spring device utilizes an external force to cause the sleeve rod to rotate along a counter-clockwise direction, the multilayer constant-torque torsion spring fixed on the winding wheel can be wrapped on the winding wheel. When the external force disappears, the winding wheel is rotated along a clockwise direction under the driving of the multilayer constant-torque torsion spring and the constant torque is outputted through the sleeve rod during the rotating process.
Description
Technical field
What the present invention relates to is a kind of multilayer constant force square torsion spring device, specifically, is a kind of multilayer constant force square torsion spring device for the hinge unwinding device.
Background technique
Through the literature search discovery to prior art, existing hinge unwinding device is with the power of non-contact plane spiral spring as expansion mostly, and its shortcoming is that hinge means moment in the process of launching changes, and is easy to generate shake and impact.
Summary of the invention
The object of the present invention is to provide a kind of multilayer constant force square torsion spring device, output constant force square is used for hinge to launch.
The present invention includes fixed plate and reel, described fixed plate both sides are respectively equipped with left hole and right hole, straight pin inserts left hole, the cylinder axis that is located at the reel center inserts right hole, the reel front is large semi-circular, and loop bar is fixed on the cylinder axis of reel, and multilayer constant force square torsion spring one side is rolled into the circular shape sky and is enclosed within on the straight pin, opposite side is centered around on the reel, and the top is fixed on the top of reel.
The present invention can perhaps increase or reduce the thickness of torsion spring by increasing or reduce the number of plies of torsion spring, regulates the size of multilayer constant force square torsion spring moment easily, adapts to different needs.
The present invention uses external force that loop bar is rotated in the counterclockwise direction, at this moment the multilayer constant force square torsion spring that is fixed on the reel will wrap on the reel, when external force disappeared, multilayer constant force square torsion spring will drive reel and clockwise rotate, and exported the constant force square by loop bar in rotation process.

Fig. 3 isMultilayer constant force square torsion spring device forming process schematic representation.
1 fixed plate, 2 multilayer constant force square torsion springs, 3 reels, 4 torsion spring screws, 5 straight pins, 6 loop bars, 7 loop bar screws, 8 cylinder axis.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described.
The present invention is made up of fixed plate 1, multilayer constant force square torsion spring 2, reel 3, torsion spring screw 4, straight pin 5, loop bar 6, loop bar screw 7 etc.Be provided with cylinder axis at reel 3 centers.
Multilayer constant force square torsion spring 2 skies of the present invention are enclosed within on the straight pin 5, one end of multilayer constant force square torsion spring 2 is fixed on the reel 3 with torsion spring screw 4, straight pin 5 is installed on the fixed plate 1, reel 3 is installed on the fixed plate 1, and loop bar 6 usefulness loop bar screws 7 are installed on the other end cylinder axis 8 of reel 3.
Working principle of the present invention: loop bar 6 is rotated in the counterclockwise direction with external force, at this moment the multilayer constant force square torsion spring 2 that is fixed on the reel 3 will wrap on the reel 3, when external force disappears, multilayer constant force square torsion spring 2 will drive reel 3 and clockwise rotate, and exports the constant force square by loop bar in rotation process.
