Abstract

The utility model provides a key. The key comprises a key handle and a key rod, wherein the key handle and the key rod are connected through a rotating shaft extending in the length direction of the key, or are connected in a rotatable and sleeved mode, the direction of the axis of the key rod is consistent with the direction of the length of the key, a blocking sheet is fixed to the key rod, a pair of limiting protrusions are fixed to the key handle, elastic bayonets are formed in the two sides of the blocking sheet respectively, the limiting protrusions can be clamped by the elastic bayonets respectively, the key is provided with a locked mark and an unlocked mark, fluorescent surfaces serve as the surface of the locked mark and the surface of the unlocked mark, and the locked mark and the unlocked mark can be seen at night. By the adoption of the key, when locking is carried out, the key handle moves relative to the key rod; after a door is locked, the position of the key rod relative to the key handle is different from the position of the key rod relative to the key handle before the door is locked; when unlocking is carried out, the key handle rotates relative to the key rod, the position of the key rod relative to the key handle is the same as the position of the key rod relative to the key handle before the door is locked; a user can learn about whether locking is accomplished or not according to the position of the key rod relative to the key handle.

Description

A kind of key

Technical field

The utility model belongs to lockset field, relates to a kind of key.

Background technology

Because people go out or close after safety cabinet leaving home, uncertain door or the safety cabinet of oneself whether having locked sometimes.To return and check lockset in order to determine whether lockset has also been locked, also must go back to check, waste people's time, also affect people's mood.Particularly, to the poor old man of some memories, usually cause puzzlement.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of key that can point out user whether to lock a door.

To achieve these goals, the technical scheme that the utility model is taked is:

Described key, comprises the shank of the key, key bar and key bit, and described key bit is located at described key bar one side, and described the shank of the key has the front and back that can distinguish, and described key bar is rotatably installed on described the shank of the key; One in described the shank of the key and described key bar is fixed with a pair of spacing preiection, and another is fixed with the catch that blocks described spacing preiection.

Described the shank of the key both sides are respectively equipped with locks mark and does not lock mark.

Described locked mark and the described mark of not locking there is face.

The front of described the shank of the key and the one side of described key bar scribble the fluorescent paint of same color, and the back side of described the shank of the key and the another side of described key bar scribble the fluorescent paint of another kind of color.

Described catch is provided with the elastic bayonet lock coordinating with described spacing preiection.

Adopt technique scheme, because the rotation direction of key bar is consistent with key length direction.In the time locking, the shank of the key rotates relative to key bar, after locking a door the position of the relative the shank of the key of key bar from lock a door before different.In the time unblanking, the shank of the key rotates relative to key bar, the position of the relative the shank of the key of key bar with lock a door before identical.Whether user can understand oneself according to the position of the relative the shank of the key of key bit and lock.

Described the shank of the key both sides are respectively equipped with locks mark and does not lock mark.As long as see key bit towards which mark just can be understood immediately and whether lock, simple in structure, easily manufactured.

Mark has face, also can identify at night clear whether locking.

Utilize the color corresponding relation on key bar and the shank of the key surface, though do not see key bit towards, also can utilize surfaces of keys color understand whether lock.

Block spacing preiection with elastic bayonet lock, can prevent that key bar from rotating relative to the shank of the key in carrying process, determine whether to lock by key more reliably.

The specific embodiment

Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.

As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of key, comprises the shank of the key 1 and key bar 2.Between key bar 2 and the shank of the key 1, adopt rotatable socket mode to connect, the rotation direction of key bar is consistent with key length direction.The shank of the key 1 has jack, in key bar 2 some insertion the shank of the key 1.The shank of the key 1 inner side is fixed with a catch 8, is fixed with a pair of spacing preiection 7 on key bar 2, the position limiting structure that catch 8 and spacing preiection 7 base composition key bars 2 rotate.The both sides of catch 8 have the elastic bayonet lock that can block spacing preiection 7, and the both sides of catch 8 are with respect to the mid-plane symmetry of catch 8.In the time being stuck in elastic bayonet lock for one in spacing preiection 7, two spacing preiections 7 are positioned at the same side of described mid-plane, and they equate to the distance of this mid-plane.After the relative the shank of the key 1 Rotate 180 degree of key bar 2, will be blocked by above-mentioned position limiting structure, and together rotate with the shank of the key 1 like this, reach the object of locking and unblanking.Elastic bayonet lock prevents in the situation that locking or unblank, and key bar 2 rotates relative to the shank of the key 1.

Key bar 2 one sides are fixed with key bit 3, and the two-sided patterned of the shank of the key 1 is not all differentiable front and back, and are respectively equipped with in its both sides and lock mark 4 and do not lock mark 5.Lock mark 4 and do not locked mark 5 surface for face, can see at night.When key bit 3 is in the time locking mark 4 side, represent to have locked.In the time unblanking, key bar 2 is inserted in keyhole and reverses key, make the relative the shank of the key 1 Rotate 180 degree of key bar 2, key bit 3 is towards not locking mark 5.And in the time locking, be to reverse key in the other direction, can make key bit 3 again towards locking mark 4 side.So just can understand and whether lock by key.

Whether rotate also and can distinguish colored green and red fluorescent paint at the front and back of the shank of the key 1 relative to the shank of the key 1 for distinguishing key bar 2.And at the simultaneously fluorescent paint of colored red of key bar 2, the fluorescent paint of another side colored green.When the identical expression of color of key bar 2 and the shank of the key 1 the same face is locked, after key bar 2 Rotate 180 degree, the different expressions of color of key bar 2 and the shank of the key 1 the same face are unlocked.Even night do not see key bit 3 towards in the situation that, also can understand easily and whether lock.

The link outside that also spacing preiection 7 and catch 8 can be fixed on to key bar 2 and the shank of the key 1 in specific embodiment, the anglec of rotation of restriction key bar 2 is 180 degree.Between key bar 2 and the shank of the key 1, also can connect by the rotating shaft of extending along key length direction.

By reference to the accompanying drawings the utility model is carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
