Description
Technical field
A kind of hinge with auto-lock function is the utility model is related to, more particularly to a kind of band used on double ladder certainly
The hinge of lock function.
Background technology
Double ladder includes left ladder row and right ladder is arranged, and left ladder row and right ladder row are rotatablely connected by hinge, relative can be turned
It is dynamic to realize folding and opening.The structure of hinge also has many kinds, band auto-lock function can be substantially divided into by function and without self-locking
Two kinds of function.Without the hinge of auto-lock function, left ladder row and right ladder come and are likely to relatively rotate in any case, receive
Easily it is opened accidentally under folding state, needs someone to help surely during use, or pull bar is set again in addition to hold left ladder row and right
Ladder row, it is therefore, actually and impracticable without the hinge of auto-lock function.Hinge with auto-lock function, when left ladder row and right ladder arrange
When relatively rotating to desired angle, hinge can be prevented left ladder row and right ladder row from rotating, consolidate ladder, have very with self-locking
Good practicality.
But the existing hinge with auto-lock function using it is upper be all to occur in pairs, two hinges are separately mounted to ladder
Both sides, that is to say, that a hinge connection it is left and right ladder row top side, another hinge connection it is left and right ladder row top
Opposite side, it is necessary to be operated respectively to two hinges during manual operation unblock or self-locking, in-convenience in use.
Utility model content
The utility model provides a kind of hinge with auto-lock function, which overcomes the deficiency present in background technology.This
Technical scheme is used by utility model solves its technical problem：
A kind of hinge with auto-lock function, including two front connecting pieces and two rear connecting pieces, two front connecting pieces can turn
Dynamic is stacked together, and two rear connecting pieces are rotatably stacked together, in addition to rotating shaft, preceding latch and rear latch, this turn
Axle passes through the front connecting piece and rear connecting piece, and two front connecting pieces are located at rotating shaft front portion and can turned by axle center of the rotating shaft
It is dynamic, two rear connecting pieces be located at the rotating shaft rear portion and can using the rotating shaft as axis rotation, the rotating shaft can drive the preceding latch with
Synchronizing moving, the front connecting piece are provided with the lockhole for the preceding latch insertion, set on the rear connecting piece latch vertically afterwards
There is the lockhole for the rear latch insertion；
During self-locking, the rotating shaft is moved axially towards first direction drives the preceding latch to be inserted among two front connecting pieces, should
Latch is inserted among two rear connecting pieces afterwards；
During unblock, the rotating shaft is moved axially towards second direction drives the preceding latch to exit the lockhole of front connecting piece, after this
Latch exits the lockhole of rear connecting piece.
Compared with background technology, it has the following advantages that the technical program：
The rotating shaft strings two front connecting pieces and two rear connecting pieces, meanwhile, the rotating shaft can drive the preceding latch and rear latch
Synchronizing moving is, it is necessary to when self-locking or unblock vertically, it is only necessary in the operation rotating shaft axial movement of rotating shaft side, it is possible to synchronous control
Make preceding latch and rear latch movement and realize locking and unblock into and out of lockhole, there is the advantages of easy to operate.
