Bearing 21, upper plane bearing 22, to make on the link block 16 and helical rotation part 23 on the top of cylinder on power transmission pin shaft 13
Prismatic through-hole 24 cooperates；16 upper surface of link block is provided with threaded hole, when the prismatic on link block 16 and helical rotation part 23 is logical
After hole 24 cooperates, setting fixing bolt 29 is threadedly coupled with threaded hole, and the diameter of the nut portion of fixing bolt 29 is greater than prismatic
Through-hole 24, so that link block 16 be made to be fixedly connected with helical rotation part 23；
As shown in figure 3, the lateral wall of helical rotation part 23 is cylinder, helical rotation part 23 can be in upper 3 inner circumferential of through-hole
Rotation；Arc panel there are two being upwardly extended in the upper end of helical rotation part 23, the shape of arc panel and 11 lower end of spiral sliding part
Adaptation, i.e., arc panel is similarly provided with arc, and seen from above in the figure, the extending direction of the curved surface of arc is counterclockwise
Direction；Semi-circular recesses 25 are provided with below 11 arc lower plate of spiral sliding part；Helical rotation part 23 arc panel it is upper
Side position corresponding with 11 upper half circular groove 25 of spiral sliding part is provided with semi-cylindrical hill 26, the shape of semi-cylindrical hill 26
With the shape adaptation of semi-circular recesses 25；
The present invention in actual use, rotates one of hinge, such as hinge bottom sheet 2 because power transmission pin shaft 13 with
Lower through-hole 4 is interference fitted, and will be will drive power transmission pin shaft 13 during rotation and be rotated, and the link block 16 on power transmission pin shaft 13 rotates
To drive helical rotation part 23 to rotate, (original state of the invention, helical rotation part 23 and spiral sliding part 11 are in cooperation
State, i.e. the arc of the two is in mated condition), because of four protrusions 12 and upper 3 inner wall of through-hole on spiral sliding part 11
The reason of upper locating slot 5 is adapted to, helical rotation part 23 can only push 11 upward sliding of spiral sliding part in the case where rotating, without
It is the drive rotation of spiral sliding part 11, so that the spring 10 of 11 pairs of tops of spiral sliding part is squeezed, the top of spring 10
It offsets with gasket 7, and gasket 7 is then limited by the adjusting screw of more top 9 and decoration king bolt 6, then spring 10 is extruded place
In energy storage state；When hinge bottom sheet 2 is no longer rotated, that is, in the case where not stressing, the spiral sliding part 11 of 10 pairs of lower sections of spring
It squeezes, makes spiral sliding part 11 and helical rotation part 23 that there is the trend for restoring mated condition, it is same because of spiral sliding part
The reason of four protrusions 12 on 11 are adapted to locating slot 5 on upper 3 inner wall of through-hole, spiral sliding part 11 is not able to rotate, Zhi Nengxiang
Lower movement drives helical rotation part 23 to rotate, reverse to drive 13 turns of power transmission pin shaft in the case where helical rotation part 23 rotates
Dynamic, power transmission pin shaft 13 drives hinge bottom sheet 2 to reset；If hinge is mounted on a door, the specific effect that product generates is exactly when making
After user pushes the door open, door can automatically reset；And the semi-circular recesses 25 and helical rotation being arranged on spiral sliding part 11
The effect for the semi-cylindrical hill 26 being arranged on part 23 is then to play position-limiting action, after the certain angle of hinge rotating opening, such as
After 90 degree, semi-circular recesses 25 and semi-cylindrical hill 26 cooperate, and the hinge made is in the case where no longer rotating, spiral sliding part 11
And the trend of the recovery mated condition of helical rotation part 23 is locked；If hinge is mounted on a door, product is generated specific
Effect is exactly after door is pushed open certain angle or pushed open completely by user, and the auto-reset function of door is limited, such as
Fruit user wants to close the door, it is also necessary to apply other power again, door could be shut；The adjusting screw 9 decorated in king bolt 6 can
With relative position of the adjusting gasket 7 in upper through-hole 3, because 10 both ends of spring are in the state of limit (by gasket 7 and spiral shell
Revolve sliding shoe limit), when the position change of gasket 7,10 confined state of spring can also change, when hinge is resetted, such as
The deformation quantity that fruit spring 10 is generated by the compression of gasket 7 is bigger, then hinge is resetted (i.e. spiral sliding part 11 and helical rotation
Part 23 restore mated condition) speed it is faster, the effect of adjusting screw 9 just with by adjusting adjusting screw 9 in upper through-hole 3
Position, thus adjustable hinge reset speed, it can change the reset speed of door.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to restrict the invention, all in design structure of the invention
Within think of, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
