Abstract
Prevent forgetful key, be a kind of key that user's door can be reminded whether to lock.Key body is divided into head and afterbody, is linked by latch structure, and realizes simple spinfunction.By the mark of key head, the purpose for reminding user's door whether to lock is reached.Key body is divided into two parts by the utility model, and the part being not inserted into lock is improved.Mainly there are spring and 4 guide grooves, according to use habit, rotate key when locking a door (to the left) to the right, then turn round and made marks on handle position in key, lock is opened by pressing naturally when locking a door each time, so that key is turned round handle portion and first rotated, be subsequently inserted into lock core partial turn, start action of locking a door, completion lock a door action when, key is unclamped, key is turned round handle ejection by spring automatically.After key is extracted, because the limitation of guide groove portion, now key is turned round handle and cylinder two parts and can not relatively rotated, and user can be according to mark on the key, and whether judge good by door lock.
Description
Technical field
The utility model be related to it is a kind of can indicate the key whether door lock locks, more particularly to a kind of cylinder key
People can be made prompting by spoon.
Background technology
At present, door lock on sale is divided into two kinds on the market, a kind of to be used cooperatively with normal key, another, is logical
Cross the electronic lock of the controls such as fingerprint, password, sound.Common key can be only done enabling and lock a door two and act, this be by
Determined in the construction of key in itself, current key is formed by mould punching, so key out is one whole
Body, does not possess any specific function.Although electronic lock eliminates the trouble with key, also more safe and reliable, but face
To its high price, average family can only also hang back.At this moment a kind of key for having a specific function is accomplished by remind
Whether people door locks, meanwhile, this key had both needed solid reliability, also to keep the cheap cost of key.
The content of the invention
Always suspect whether door lock is got well into this present situation to change current people, the utility model provides a kind of special key
Spoon, the key can not only remind whether people door locks, and simply process and improve on the key existing, and removing from makes
User changes the worry of a whole set of lockset.
Prevent that forgetful key, including cylinder turn round handle as afterbody and key and be used as this two parts of head, it is characterised in that：It is logical
Cross spring and pin links two parts, there is a plurality of guide groove on cylinder, a plurality of guide groove is uniformly distributed around cylinder；Key
Torsion handle is cavity structure, is realized with cylinder mutually nested；Key is turned round and places spring, key between the cavity structure and cylinder of handle
Spoon is turned round and multiple windows is uniformly arranged on handle, and is through to cavity, and window size should be adapted with guide groove size on cylinder；Pin
It is stuck in guide groove, is used cooperatively with guide groove by interference fit.
Further, four guide grooves are set on the cylinder,
Further, cylinder is a stepped shape, and has positioning shaft shoulder, and guide groove is arranged on thinner one of cylinder
End.
Further, the thinner one end of cylinder and key, which are turned round, is respectively provided with a circular shallow hole in handle cavity, be easy to fix spring.
Thirdly selectively, it is cavity structure that key, which turns round handle, can be realized with cylinder mutually nested.
Thirdly selectively, cylinder and key, which are turned round, sets a circular shallow hole in handle cavity, be easy to fix spring, key is turned round
Four windows are uniformly arranged on handle, and are through to cavity, window size should be adapted with guide groove size on cylinder.
On the basis of original key, secondary operation is carried out, key body is divided into two parts, to the portion being not inserted into lock
Divide and be improved.Mainly there are spring and 4 guide grooves, according to use habit, rotate key when locking a door (to the left) to the right, then in key
Spoon is turned round to make marks on handle position, opens lock by pressing naturally when locking a door each time so that key is turned round handle portion and first rotated, with
Insert lock core partial turn afterwards, start action of locking a door, completion lock a door action when, unclamp key, spring is automatically by key torsion handle top
Go out.After key is extracted, because the limitation of guide groove portion, now key, which turns round handle and cylinder two parts, can not occur phase
To rotating, user can be according to mark on the key, and whether judge good by door lock.During enabling, key is rotated (to the right) to the left
Spoon, lock is opened by pressing naturally so that key is turned round handle portion and first rotated, and is subsequently inserted into lock core partial turn, completes to open the door
During action, key is unclamped, key is turned round handle ejection by spring automatically, and now, the mark that key is turned round on handle is converted, key mark
Place shows that door is in non-lock status, and is easy to lock a door next time.
The beneficial effects of the utility model are, can be while not influenceing normal door and locking a door, by key
Improve and process, realize the purpose for reminding people door whether to lock.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Lower Fig. 1 is mechanical schematic diagram of the present utility model.
Fig. 2 is head figure of the present utility model.
Fig. 3 is spring figure of the present utility model.
Fig. 4 is afterbody figure of the present utility model.
1. cylinder in figure, 2. keys turn round handle, and 3. springs, 4. pins, 5. guide grooves, 6. shallow mouths are circular
Embodiment
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
As shown in figure 1, the utility model key includes cylinder 1 and key turns round handle 2, one end of cylinder 1 and key are turned round
Handle 2 is connected by pin 4, to complete spinning movement.
Embodiment one
As shown in Fig. 2 the part that key torsion handle 2 is combined with cylinder 1 is cavity structure, cavity bottom is provided with and spring
The equal shallow mouth circle 6 of 3 diameters, the diameter of cavity should be equal with the stepped portion minimum diameter of cylinder 1, the length of cavity with
The less length of diameter is identical on cylinder 1, and key is turned round and is uniformly provided with four through holes on handle 2, with the guiding on cylinder 1
Groove 5 cooperates.And can be when needed that guide groove 5 fills lubricating fluid by through hole,
Embodiment two
