Parallel, interval is oppositely arranged；The inner hinge component is put together by two pieces of inner hinge pieces, and its head is provided with inner disk；Two institutes
The both sides that outer disc is clamped in the inner disk are stated, and are hinged by central shaft；
Wherein, the outer hinge component also includes an internal partition and a straight pin；The internal partition fitting is arranged at two
Between the outer hinge plate, for supporting two outer hinge plates；The straight pin is horizontally positioned between the two outer hinge plates, right
The outer rim of the inner disk is answered to set, also, the straight pin is located in the tangential direction of inner disk, and composition works as the inner hinge
Component and the outer hinge component do Unscrew along the central shaft, and when to open subtended angle be 180 °, the straight pin will support
It is against in the outer rim of the inner disk, and then prevents inner hinge component from continuing to open with outer hinge component.
Relevant content in above-mentioned technical proposal is explained as follows：
1. in such scheme, the outer hinge component also includes two external partitions, two external partitions are pasted and are positioned at respectively
The outside of the two outer hinge plates；The straight pin is arranged in the two outer hinge plates and the internal partition, and the two of straight pin
End is respectively positioned in two external partitions.
Utility model works principle and advantage are as follows：
A kind of double ladder hinge locating mechanism of the utility model, including outer hinge component, inner hinge component；Outer hinge component
By two pieces of outer hinge plates it is parallel, interval be put together；Inner hinge component is put together by two pieces of inner hinge pieces；Outer hinge component
Two outer discs are clamped in the both sides of inner hinge component inner disk, and are hinged by central shaft；Outer hinge component also includes internal partition
And straight pin；Internal partition is located between two outer hinge plates, and straight pin is positioned between two outer hinge plates, and the outer rim of corresponding inner disk is set
Put, and straight pin is located at the tangential direction of inner disk, form when inner hinge component and outer hinge component along central shaft open to
At 180 °, straight pin prevents inner hinge component from continuing to open with outer hinge component by against the outer rim of inner disk.Compared to existing skill
For art, designed by innovation structure of the present utility model, operator's double ladder easy to operation can be assisted to be opened into yi shaped ladder
When, the hinged place both sides locking mechanism of left half ladder and right half ladder is in working condition, and then the structure of yi shaped ladder is protected
Shield, while the personal safety of user is ensure that, and there is simple in construction, lower-cost advantage.
