Abstract
The invention discloses a hand-pulling unlocking mechanism of a base and an automobile hook. The hand-pulling unlocking mechanism of the base and the automobile hook comprises a base upper cover, a base lower cover, a base fixing support, a hand-pulling hook, a linkage mechanism and at least one locking hook. A locking hook locking resetting mechanism is arranged corresponding to each locking hook, and a first notch is formed in the rear end of the base fixing support. The locking hook locking resetting mechanism can drive the locking hooks to rotate by a set angle so as to enable the locking hooks and the first groove opening to form an annular buckle used for buckling the hook in an enclosing mode at the initial position. The hand-pulling hook can drive the locking hook locking resetting mechanisms through the linkage mechanism under the action of external force, so that the locking hook locking resetting mechanisms drive the locking hooks to rotate by a set angle in the opposite direction, and the annular buckle is separated from the hook. After the external force is relieved, the locking hook locking resetting mechanisms can drive the locking hooks to reset to the initial position, and drive the hand-pulling hook to reset through the linkage mechanism. The hand-pulling unlocking mechanism of the base and the automobile hook can achieve assembly and unlocking of the base and an automobile conveniently, is simple and convenient to operate, full of humanization design, reliable in locking and high in safety.
Description
Technical field
