Axis hole is offered on motion block；The positioning seat includes positioning plate and the link block for being symmetrically disposed on the positioning plate two sides；It is described
Rotating block is placed between the link block of the positioning plate two sides, is offered on the link block of two sides coaxial with the axis hole
The location hole of setting；The bolt includes body and the bolt cap for being placed in described body one end, and the body is described through two sides
The axis hole on location hole and the rotating block on link block, the bolt cap are placed on the link block of the positioning plate side, institute
The other end for stating body is anchored on the link block of the positioning plate other side；Torsion bullet is equipped in the axis hole of the rotating block
Spring, the body pass through torsionspring, and the end of the torsionspring is fixed on the link block of the positioning plate side, described
Rotating block side on rotation seat is symmetrically arranged with convex block, and the side link block on the positioning seat is equipped with matches with the convex block gap
The groove of conjunction.
Above-mentioned overload protection type hinge is equipped between the torsion spring end and the link block of the positioning plate side
Spring washer.
The other end of above-mentioned overload protection type hinge, the body is anchored on the positioning plate other side by nut
On link block.
Above-mentioned overload protection type hinge, the bolt are interior six point cylindrical head bolts.
Above-mentioned overload protection type hinge, the nut are turret head locking nuts.
The advantages of the utility model overload protection type hinge, is:
1, the utility model overload protection type hinge protects torsionspring not by the damage of overload torsion, improves torsionspring
Service life, improve the reliability of torsionspring；The hinge is safe and reliable, convenient for rotation, has good practical value.
2, the utility model overload protection type hinge, rotation seat and positioning seat are opened and closed by torsionspring and pass through rotation
The limit of hinge opening and closing is realized in convex block and the groove gap cooperation being arranged on seat and positioning seat, and torsionspring, which is fixed by bolts to, to be turned
On dynamic seat and positioning seat；When positioning seat is fixed, rotation seat rotates under the action of certain torsion, and rotating distance is hinge two
Corner between convex block.When rotation seat is by torsionspring acrotorque value is greater than, the convex block of rotation seat rotates to positioning seat
Blocked after groove by the groove of positioning seat and no longer rotate, torsionspring is no longer influenced by the twisting force of overload, torsionspring by
It will not be damaged to protection.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Embodiment 1, a kind of as shown in Figure 1,2,3, 4, overload protection type hinge, including rotation seat 1, positioning seat 2, bolt 3；
The rotation seat 1 includes rotor plate 12 and the rotating block 13 being set on the rotor plate 12, offers on the rotating block 13
Axis hole 14；The positioning seat 2 includes positioning plate 21 and the link block 22 for being symmetrically disposed on 21 two sides of positioning plate；The rotation
Block 13 is placed between the link block 22 of 21 two sides of positioning plate, is offered on the link block 22 of two sides and the axis hole
The location hole 23 of 14 coaxial arrangements；The bolt 3 includes body 31 and the bolt cap 32 for being placed in described 31 one end of body, the body
31 axis hole 14 on the location hole 23 and the rotating block 13 on the link block 22 of two sides, the bolt cap 32 are placed in institute
