The technical matters that the utility model solves realizes by the following technical solutions:
A kind of front fork folding device of double-lock structure, in the middle part of the front fork being arranged on bicycle, in order to connect two sections, the front and back of described front fork, comprise front body, rear body and rotating shaft, described front body and rear body are linked together by rotating shaft twisting, and form the folding main body that can overturn flexibly;
Described front body is provided with the eccentric locking mechanism that can freely overturn;
Body is fixed with the second latching device in the rear, described second latching device is made up of mother's pipe, spring, locking post and groove, described spring housing is arranged in described female pipe after being located at locking post, the top of described locking post protrudes from female pipe, and is connected with the groove fit be arranged on described front body.
As preferred technical scheme, the top of described locking post is spherical structure.
As preferred technical scheme, the middle part of described front body is provided with two root posts, between two described columns, be provided with S. A., and described eccentric locking mechanism is arranged on described S. A. by pull bar.
As preferred technical scheme, described groove is arranged on the sidewall of described column, to realize the steady closure of described front body and rear body.
Conveniently unlocking operation, the end of described locking post protrudes from described mother's pipe, and is provided with handle, so that unlocking operation.
As preferred technical scheme, the top of described column is provided with inclined-plane, so that described front body and rear body closed procedure.
As preferred technical scheme, the middle part of described rear body is provided with the protrusion district coordinated with described eccentric locking mechanism, to realize Camlock.
The beneficial effect that the utility model has is: by the setting of the front and back body that mutually twists and link and eccentric locking mechanism and the second latching device, ensure that the use safety of folding device, simultaneously easy to operate, is suitable for applying.
