Description

A kind of luminous door lock

Technical field

The utility model relates to door lock, relate in particular to a kind of can be under dark surrounds self luminous door lock.

Background technology

When opening the door night, if near do not have illuminating lamp, under the situation that perhaps illuminating lamp damages; Because the keyhole of door lock is very little, make people make when turning the key in the lock, be difficult to find the tram of keyhole; Even find the position of keyhole, for some circular keyholes, the direction of not looking for the slotting key of correct; Also can't correctly unblank, this makes troubles to people.

The utility model content

The purpose of the utility model provides a kind of luminous door lock, can self-luminous, under dark surrounds, also can clearly discern the position and the direction of keyhole.

To achieve these goals, the utility model embodiment provides a kind of luminous door lock, comprising:

Lock tube;

Lock core is installed in rotation in the said lock tube;

Keyhole is arranged on the said lock core;

First luminescent layer by phosphor material forms covers on the external surface that is arranged at said keyhole lock core all around.

Above-mentioned luminous door lock also comprises:

By second luminescent layer that phosphor material forms, covering is arranged on the external surface of said lock tube.

The luminous door lock of the utility model has following beneficial effect:

When 1, this door lock perhaps has light-illuminating by day; Luminescent layer of coating can absorb energy on it, and changes the energy that absorbs into visible light, when do not have sunshine or light-illuminating night; It still can continue luminous, clearly discerns the position and the direction of keyhole to make things convenient for the user.

2, the luminescent layer that on lock tube, is coated with is luminous at night, makes that luminous door lock is more eye-catching.

3, because the initial briliancy of luminescent layer is every square metre of 7400cd, therefore can guarantee door lock at any time all be in luminous state more than 80 hours visual persistence.

Description of drawings

Fig. 1 is the structural representation of the luminous door lock of the utility model.

The specific embodiment

The luminous door lock of the utility model embodiment; Around keyhole, be coated with first luminescent layer that one deck is formed by phosphor material; When receiving light source irradiation, this luminescent layer absorbs energy; And change the energy that absorbs into visible light, and can continue after stopping luminously exciting, therefore can clearly discern the position and the direction of keyhole.

Be illustrated in figure 1 as the structural representation of the luminous door lock of the utility model, this luminous door lock comprises:

Lock tube 101;

Lock core 102 is installed in rotation in the said lock tube 101;

Keyhole 103 is arranged on the said lock core 102;

By first luminescent layer (scheming not shown) that phosphor material forms, cover on the external surface that is arranged at said keyhole 103 said lock core 102 all around.

Certainly; Foregoing first luminescent layer covers on the external surface of said keyhole 103 said lock core 102 all around, and it can remind the user to find the position and the direction of keyhole 103 fast; In order to make said luminous door lock more eye-catching, this luminous door lock also comprises:

One second luminescent layer that formed by phosphor material covers on the external surface of said lock tube 101.

Like this, whole door lock can both emit beam at night, and not only luminosity, luminous volume all can increase, and had strengthened the function of reminding greatly.

In the specific embodiment of the utility model; In order to guarantee that luminous door lock can both emit beam at any time; Phosphor material can adopt artificial synthetic long Persistence and high brightness fluorescent materials to process; This long Persistence and high brightness fluorescent materials is a matrix with the alkali earth metal aluminate of boracic, and more than one RE element is an activator, and its chemical molecular formula is: MO _n[(Al _1-aB _a) _2-b/3O _3-b(OH) _b]: cRE, wherein:

M representes to be selected from least a alkaline-earth metal in magnesium, calcium, strontium or the barium;

RE representes to be selected from lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, at least a rare earth element in the lutetium;

N is smaller or equal to 10, more than or equal to 0.5;

A is smaller or equal to 0.5, more than or equal to 0.0001;

B is smaller or equal to 2, more than or equal to 0.0001;

C is smaller or equal to 0.6, more than or equal to 0.0001;

Part is by OH displacement at least for oxygen atom in the crystal structure that burns till body that above chemical molecular formula is represented, and it is to carry out wet grinding through the material solution with one or more, makes each composition in the raw material be ground to particle diameter and prepares for the 50-10000 nanometer.

And the synthetic long Persistence and high brightness fluorescent materials of above-mentioned manual work can prepare through following method:

At first, take by weighing raw material, and it is ground to particle diameter is the 50-10000 nanometer by proportioning;

Secondly, the raw material after grinding is inserted crucible, and this crucible is put into the pressure electric furnace, under reducing atmosphere, calcining is 2-5 hour under the 600-1200 degree celsius temperature;

Once more, will burn till body and from electric furnace, take out cool to room temperature;

At last, the cooled body that burns till is ground to form powder.

The initial briliancy of the luminescent powder of preparation is every square metre of 7400cd as stated above, and visual persistence is more than 80 hours.

Certainly; Should be understood that above-mentioned phosphor material also can other phosphor material, like disclosed phosphor material in No. 95109878.0 patents; And for example disclosed phosphor material etc. in 97100694.6,99100285.7, No. 98123460.7 patents is not described at this one by one.

The luminous door lock of the utility model has following beneficial effect:

By second luminescent layer that phosphor material forms, covering is arranged on the external surface of said lock tube.

The luminous door lock of the utility model has following beneficial effect:

When 1, this door lock perhaps has light-illuminating by day; Luminescent layer of coating can absorb energy on it, and changes the energy that absorbs into visible light, when do not have sunshine or light-illuminating night; It still can continue luminous, clearly discerns the position and the direction of keyhole to make things convenient for the user.

2, the luminescent layer that on lock tube, is coated with is luminous at night, makes that luminous door lock is more eye-catching.

3, because the initial briliancy of luminescent layer is every square metre of 7400cd, therefore can guarantee door lock at any time all be in luminous state more than 80 hours visual persistence.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
