Improved hinge unlocking mechanism
The invention relates to an improved hinge unlocking mechanism which comprises a first hinge plate and a second hinge plate which can rotate relatively, the second hinge plate is provided with a limiting notch, the first hinge plate is slidably connected with a check block, and the first hinge plate is hinged to a handle shifting handle on one side of the check block through a shifting handle pivot. The handle shifting handle comprises shifting plates arranged on the upper side face and the lower side face of the first hinge plate in parallel respectively, the same sides of the two shifting plates are connected through a ridge plate, the shifting plates are provided with hinge holes matched with the shifting handle pivot and auxiliary holes used for shifting the check blocks, and the shifting plates are provided with vertical faces abutting against the surface of the first hinge plate on the inner sides of the peripheries of the auxiliary holes. The outer side faces of the shifting plates are not lower than the surfaces of the corresponding check blocks. The hinge is simple in structure, the two ends of the check block can be prevented from being exposed out of the first hinge plate, the situation that the check block slides in the unlocking direction due to the fact that falling objects hit the check block or a user steps on the check block by mistake, and consequently the hinge is unlocked accidentally is completely avoided, and the product safety is improved.
本发明涉及一种改进的铰链开锁机构，包括可相对转动的第一铰链板和第二铰链板，所述第二铰链板设有限位槽口，所述第一铰链板滑动连接有挡块，所述第一铰链板在挡块一侧通过拨把枢轴铰接有拉手拨把，所述拉手拨把包括分别平行设于第一铰链板上下两侧面的拨板，两个拨板同侧通过脊板连接，所述拨板均设有与拨把枢轴相适配的铰接孔及用于拨动挡块的工艺孔，所述拨板在工艺孔环周内侧设有抵接至第一铰链板表面的立面，所述拨板外侧面均不低于与其对应的挡块表面。本发明结构简单，可避免挡块两端暴露在第一铰链板外部，完全避免落物砸到挡块上或使用人员误踩到挡块上而造成挡块向开锁方向滑动，导致铰链意外开锁，使产品安全性得以提高。
