Detailed description of the invention
With reference to figure 1-4, a kind of memory key, comprising: open portion 1 and grip part 2, and described open portion 1 is rotationally connected with described grip part 2 by a rotation section 3; Described grip part 2 and rotation section 3 are provided with the limiting section 4 of working in coordination mutually, limit the angle that described open portion 1 is rotated relative to grip part 2.
Concrete structure is: described grip part 2 has an installing hole 21, and described rotation section 3 is installed in described installing hole 21.Described limiting section 4 comprises the stopper slot 41 being located at rotation section 3 and the limited block 42 being located at grip part 2; When rotating described rotation section 3, described limited block 42 moves to the other end by one end of stopper slot 41.
Described rotation section 3 turn to limited block 42 parallel with the bottom surface of stopper slot 41 time, the end of described limited block 42 is positioned at the half of described stopper slot 41 degree of depth.Described rotation section 3 is 90 ° relative to the angle that grip part 2 is rotated.
Described spacing 42 pieces is the first screw, and described grip part 2 is provided with the first screw hole 22, and its one end is communicated to the side of described installing hole 21.
Described limiting section 4 also comprises the first locating slot 43 and the second locating slot 44 being located at side, rotation section 3, and is located at the elastic projection 45 of grip part 2; When described limited block 42 moves to the other end by one end of described stopper slot 41, described elastic projection 45 moves to the second locating slot 44 by the first locating slot 43.
Described grip part 2 is provided with the second screw hole 23, and its one end is communicated to the side of described installing hole 21.
Described elastic projection 45 comprises interior and the outer steel ball 451 be located at successively in described second screw hole 23, spring 452 and the second screw 453.
The torsion when elastic force of described elastic projection 45 is less than key unlocking or locks.
The operating principle of above-mentioned key is:
Before user locks: open portion 1 and grip part 2 are in parastate, and steel ball 451 is arranged in the first locating slot 43, limited block 42 is spacing with one end contact of stopper slot 41.
When user locks, rotate counterclockwise key.Torsion due to key back locking is greater than the elastic force of elastic projection 45, therefore steel ball 451 extrusion spring 452, and steel ball 451 departs from from the first locating slot 43.Rotation section 3 and grip part 2 relatively rotate, and limited block 42 moves to other end contact spacing in stopper slot 41, and steel ball 451 falls into the second locating slot 44.Now open portion 1 have rotated 90 ° relative to grip part 2, and open portion and grip part are mutually vertical.
Before user unlocks: open portion 1 and grip part 2 are in plumbness, and steel ball 451 is arranged in the second locating slot 44, limited block 42 is spacing with the other end contact of stopper slot 41.
When user unlocks, rotate clockwise key, the torsion due to key unblock is greater than the elastic force of elastic projection 45, and therefore steel ball 451 extrusion spring 452, steel ball 451 departs from from the second locating slot 44.Rotation section 3 and grip part 2 relatively rotate, and limited block 42 moves to one end contact spacing in stopper slot 41, and steel ball 451 falls into the first locating slot 43.Now open portion 1 have rotated 90 ° relative to grip part 2, and open portion and grip part are parallel to each other.
Therefore, user, by observing open portion 1 and the relative position of grip part 2, can judge whether opposite house is locked, fast very convenient.Avoid occurring user because memory is unclear and repeatedly checking whether door lock locks the waste of the time and efforts brought.
In the present embodiment, open portion 1 and grip part 2 in relative rotation angle are 90 °, also can be designed as other angles, belong to the simple replacement of the present embodiment, repeat no more.
In addition, originally be the elastic force of embodiment Elastic projection 45 torsion when being less than key unlocking or locking, therefore unblank again or lock when carrying out, open portion 1 and grip part 2 will relatively rotate, the torsion when elastic force that also can be designed to elastic projection 45 is greater than key unlocking or locks, like this after unblanking or locking end, be rotated further key and also can realize the object that open portion 1 relatively rotates with grip part 2.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process according to this, the equivalence change namely done according to the scope of the claims of the present invention and description with modify, all should still belong in scope that the present invention contains.
