Safety hook structure of engine hood lock
The invention discloses a safety hook structure of an engine hood lock, which comprises a base, a hook body, a first elastic piece and a second elastic piece, and is characterized in that the base is used for being detachably fixed on a vehicle body; the hook body comprises a mounting part, a limiting part, a handle part and a hooking part, the lower end of the mounting part is rotationally mounted on the base, the limiting part is fixed to one end of the mounting part, the handle part is fixed to the other end of the mounting part, and the hooking part is arranged between the limiting part and the handle part and is close to the limiting part; the lower end of the hooking part is rotationally mounted on the mounting part; the two ends of the first elastic piece are fixedly connected with the base and the installation part respectively. The safety hook has the beneficial effects that after a primary lock is unlocked, on the premise that the arrangement space of the safety hook is not increased, the engine hood is allowed to be lifted by a larger height, and therefore the requirement that the hand of an operator stretches into an operation handle part is met.
本发明公开了一种发动机罩锁的安全钩结构，其包括底座、钩体、第一弹性件及第二弹性件，所述底座用以可拆卸固定于车体上；所述钩体包括安装部、限位部、手柄部及钩取部，所述安装部的下端转动安装于所述底座上，所述限位部固定于所述安装部的一端，所述手柄部固定于所述安装部的另一端，所述钩取部设置于所述限位部和所述手柄部之间，并靠近所述限位部，所述钩取部的下端转动安装于所述安装部上；所述第一弹性件的两端分别与所述底座和所述安装部固定连接。本发明的有益效果是：在一级锁解锁后，本安全钩在不增大其布置空间的前提下，允许发动机罩抬起更大高度，从而满足操作人员手伸入操作手柄部的需求。
