Description

A kind of memory key of recordable door interlock switch state

Technical field

The utility model is related to a kind of key technical field, more particularly to a kind of memory key of recordable door interlock switch state Spoon.

Background technology

During people's go off daily, door lock ＆ key is generally all be unable to do without, but as the species of lock is more and more, people Be sometimes difficult to judge whether door lock is locked really, cause unnecessary operation, or even the damage for causing lockset or key It is bad.

At the same time, as rhythm of life is more and more faster, various pressure are increasing, need to process many things daily, Go out daily it is too worried it is very possible door is forgotten into lock, oneself has been closed clearly sometimes, but not steady and sure at heart, is looked back at Number of times is not within minority.But at present without other method, waste substantial amounts of time for no reason in addition to going to check in person.

In order to overcome drawbacks described above, people have invented many key of memory function, such as Patent No. 201320414225.2nd, entitled ball bead type memory key and Patent No. 201420372343.6, entitled one kind are recordable The Chinese patent of the memory key of door interlock switch state is exactly the key with memory function, and simple structure records the switch of door State, is the on off state that can be appreciated that door by peep hole, using simple.It is convenient for people to from key external observation door lock State is locked, forgets whether door lock is locked when people go out in preferably solving the problems, such as to live.

But the defect of above-mentioned several memory keys is：The position of the shank of the key of portion of the handle and the key core of unlocking part Relative change is sea level changes, namely from the position of display switch to the position of display locking mobile route for one it is straight Line, centre causes the locking of this relative position and unreliable without displacement and change, causes the distortion of memory function.

Utility model content

The purpose of this utility model is to provide a kind of memory key of recordable door interlock switch state, and recordable door lock is opened Off status, the lock-out state of the memory key is relatively good, it is to avoid distortion, people can be helped to judge door interlock switch state, preferably Solve the problems, such as life in people forget whether door lock is locked when going out, to careless, rhythm of life is fast, memory Difference, the crowd for having obsession etc. bring conveniently.

To achieve these goals, the utility model technology is realized in such a way：

A kind of memory key of recordable door interlock switch state, including hand-held key handle, for inserting gate locked groove To open the key core at gate；The key core has a rotating shaft end that can rotate and be drilled with pin hole, the rotating shaft End is provided with one and passes through pin hole and the pin for having an end head to expose from the periphery of rotating shaft；One end of the shank of the key sets The sleeve that a rotating shaft end for making key core is inserted and rotated is equipped with, the circumference of the sleeve offers man type chute, when described Key core is inserted into when in sleeve, and the part exposed of the pin is snapped onto in man type chute；The rotating shaft end of the key core End face and sleeve bottom end face between be provided with back-moving spring.

As the improvement to above-mentioned technical proposal, the pin and pin hole with being combined into interference fit.In this way, pin is tight It is close to be inserted into the pin hole of rotating shaft, can prevent pin from being come off with the loosening of rotating shaft.

Used as the improvement to above-mentioned technical proposal, the pin coordinates with man type chute gap.So, it is ensured that rotating shaft The flexibility of relative motion between sleeve.

As the improvement to above-mentioned technical proposal, the wall thickness of the height less than sleeve of the pin exposed portion.In this way, pin Nail will not be higher by sleeve, it is to avoid hanging and pulling other articles such as clothes etc..

Used as the improvement to above-mentioned technical proposal, two bottom positions of the man type chute are provided with switch sign.

Compared with prior art, the good effect that the technical solution of the utility model is produced is as follows：

The memory key of the recordable door interlock switch state of the utility model, one in two bottoms of man type chute is to open Lock position, can be denoted as lockset position of coupler, and one is upper lock position, can be denoted as upper lock position, and the top of man type chute is Turning point；When a key inserts locked groove, before rotation is locked a door, the pin of key core is in the position unlocked.When rotation key When, relative rotation is had between key core and sleeve pipe, during key turns or when being turning fully to, pin goes to " locking " Position, after unlocking again, small projection goes to another side again.

Memory key of the present utility model, pin is from the position locked to the position unlocked, it is necessary to via turning point position, In the change procedure of position, except have it is circumferentially displaced in addition to, also key core relative to key handle axial displacement so that key Spoon core becomes more difficult from lockset position of coupler to the movement of the position locked, and when not having external force, this displacement almost turns into can not Can, it is to avoid user is not intended to the movement of pin during touching.So as to avoid distortion, the lock-out state of the memory key is relatively good, energy Enough help people to judge door interlock switch state, preferably solve people in living and forget that what whether door lock locked asks when going out Topic, to careless, rhythm of life is fast, poor memory, the crowd that has obsession etc. bring conveniently.

Brief description of the drawings

In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid Put, other accompanying drawings can also be obtained according to these accompanying drawings.
