Abstract
The utility model discloses a multilayer constant torque torsional spring device which is used for outputting constant torque so as to unfold a hinge. The multilayer constant torque torsional spring device is characterized by comprising a fixed plate and a winding wheel, wherein a left hole and a right hole are respectively formed in the two sides of the fixed plate, a cylindrical pin is inserted into the left hole, a cylindrical pin arranged in the center of the winding wheel is inserted into the right hole, the front surface of the winding wheel is in the shape of a large semicircle, a loop bar is fixed on the cylindrical pin of the winding wheel, one side of the multilayer constant torque torsional spring is rolled into a circular ring shape and is hollowly sleeved on the cylindrical pin, the other side of the multilayer constant torque torsional spring surrounds the winding wheel, and the top of the multilayer constant torque torsional spring is fixed on the top of the winding wheel. According to the multilayer constant torque torsional spring device, the loop bar rotates in an anti-clockwise direction by applying an external force, at the moment, the multilayer constant torque torsional spring fixed on the winding wheel is wrapped on the winding wheel, and when the external force disappears, the multilayer constant torque torsional spring drives the winding wheel to rotate clockwise, and the constant torque is output through the loop bar in a rotation process.
Description
Technical field
The utility model relates to a kind of multilayer constant moment of force torsion spring device, specifically, is a kind of constant moment of force of the multilayer for hinge unwinding device torsion spring device.
Background technique
Through the literature search to prior art, find, existing hinge unwinding device is the power as expansion mostly with the non-contact plane spiral spring, and its shortcoming is that hinge means moment in the process of launching changes, and easily produces shake and impact.
The model utility content
The purpose of this utility model is to provide a kind of multilayer constant moment of force torsion spring device, and the output constant moment of force launches for hinge.
The utility model comprises fixed plate and reel, described fixed plate both sides are respectively equipped with He You hole, left 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 moment of force torsion spring one side is rolled into the circular shape empty set on straight pin, opposite side is centered around on reel, and top is fixed on the top of reel.
The utility model can pass through to increase or reduce the number of plies of torsion spring, or increases or reduce the thickness of torsion spring, regulates easily the size of multilayer constant moment of force torsion spring moment, adapts to different needs.
The utility model uses external force that loop bar is rotated in the counterclockwise direction, at this moment the multilayer constant moment of force torsion spring be fixed on reel will wrap on reel, when external force disappears, multilayer constant moment of force torsion spring will drive reel and clockwise rotate, and exports constant moment of force by loop bar in rotation process.
The accompanying drawing explanation
Fig. 1 is multilayer constant moment of force torsion spring device plan view.
Fig. 2 is multilayer constant moment of force torsion spring device plan view.
Fig. 3 is multilayer constant moment of force torsion spring device forming process schematic diagram.
1 fixed plate, 2 multilayer constant moment of force 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, embodiment of the present utility model is further described.
The utility model is comprised of fixed plate 1, multilayer constant moment of force 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 moment of force torsion spring of the present utility model 2 empty sets are on straight pin 5, one end of multilayer constant moment of force torsion spring 2 is fixed on reel 3 with torsion spring screw 4, straight pin 5 is arranged on fixed plate 1, reel 3 is arranged on fixed plate 1, and loop bar 6 use loop bar screws 7 are arranged on the other end cylinder axis 8 of reel 3.
Working principle of the present utility model: loop bar 6 is rotated in the counterclockwise direction by external force, at this moment the multilayer constant moment of force torsion spring 2 be fixed on reel 3 will wrap on reel 3, when external force disappears, multilayer constant moment of force torsion spring 2 will drive reel 3 and clockwise rotate, and exports constant moment of force by loop bar in rotation process.
