Abstract
The utility model discloses a laser early warning alarm device, which belongs to technical field of the laser alarm equipment manufacturing. The alarm device comprises two support columns, wherein the two support columns are arranged side by side, and a plurality of flat mirrors arranged on the opposite side faces of the support columns; the top end of one support column is provided with a small-sized laser, and the top end of the other support column is provided with an optical detection meter which is in electric connection with a buzzer; the flat mirrors are symmetrically arranged on the support columns, and a lightening hole of the small-sized laser corresponds to the surface of the flat mirror on the topmost part of the other column; the small flat mirrors of the support columns of the alarm device can be flexibly adjusted, so that the alarm device can be used for the protection early warning alarm in precious article exhibitions; when a person gets across the warning line, the alarm device alarms to remind people of paying more attention to safety; moreover, the alarm device also has the advantages of simple structure, convenient, safety and effectiveness and the like.
Description
Technical field
The utility model discloses a kind of laser pre-warning warning device, belongs to laser warning equipment class manufacturing technology field.
Background technology
Current, various exhibition exhibitions are a lot, on show during some precious things, for safety, mainly be warning line to be set or article are placed in the cloche, so not only be not easy to the visitor and closely watch, and floor area is bigger, influences the attractive in appearance of show ground.In the risky operation zone of millwork, often use on the transparent or opaque cover cover on the other hand, be unfavorable for observing the real work situation of machine like this.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of efficient laser early warning and alarming device simple in structure, easy to use, safe.
The utility model is achieved through the following technical solutions:
The utility model comprises two pillars, wherein: described two pillars discharge side by side, and relative side is provided with a plurality of level crossings on the pillar, and there is miniature laser on a pillar top therein, another pillar top has light to detect meter, and this light detects meter and electrically connects with hummer.
Being installed on the pillar of described level crossing symmetry, and the lightening hole correspondence of miniature laser the plane minute surface of topmost on another pillar.
The facet mirror of the utility model pillar can be transferred flexibly, can be used for the protection early warning and alarming effect of precious article display, and after the people crossed warning line, device can be reported to the police, and reminds people is taken care.Also can be owing to the protection early warning and alarming effect in machine risky operation place, when the people crosses danger line because of carelessness, the hummer warning of will ringing, reminds people trouble free service, protection people's the security of the lives and property.The utlity model has advantage such as effectively simple in structure, easy to use, safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 miniature laser, 2 light detect meter 3 level crossings 4, pillar I 5 pillar II 6 buzzers.
Embodiment
Embodiment: structure as shown in the figure, the utility model comprises pillar I4 and pillar II5, wherein: described two pillars discharge side by side, relative side is provided with a plurality of level crossings 3 on the pillar, there is miniature laser 1 on a pillar top therein, another pillar top has light to detect meter 2, and this light detects meter and electrically connects with hummer 6.Being installed on the pillar of described level crossing 3 symmetries, and the lightening hole correspondence of miniature laser the plane minute surface of topmost on another pillar.
During use, adjust the angle of each facet mirror 3, can with by the light of laser instrument 1 emission through repeatedly reflecting into into photosensitive detection meter 2, so just between two pillars 4,5, formed an intensive reticule, enter between two pillars as object, will obstruct the light enters photosensitive detection meter 2, and at this moment hummer 6 will be rung.
